SUMMARY OF SIGNIFICANT ACCOUNTI

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Merger and Separation On April 1, 2019, DowDuPont Inc. (“DowDuPont” and effective June 3, 2019, n/k/a DuPont de Nemours, Inc. or "DuPont") completed the separation of its materials science business and Dow Inc. became the direct parent company of The Dow Chemical Company and its consolidated subsidiaries (“TDCC” and together with Dow Inc., “Dow” or the “Company”). The separation was contemplated by the merger of equals transaction effective August 31, 2017, under the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 (the "Merger Agreement"). TDCC and E. I. du Pont de Nemours and Company and its consolidated subsidiaries (“Historical DuPont”) each merged with subsidiaries of DowDuPont and, as a result, TDCC and Historical DuPont became subsidiaries of DowDuPont (the “Merger”). Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. See Note 3 for additional information. Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements of Dow Inc. and TDCC were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which Dow exercises control and, when applicable, entities for which Dow has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies or less than 20 percent owned companies over which significant influence is exercised) are primarily accounted for using the equity method. Effective April 1, 2019, Dow Inc. owns all of the outstanding common shares of TDCC. TDCC is deemed the predecessor to Dow Inc. and the historical results of TDCC are deemed the historical results of Dow Inc. for periods prior to and including March 31, 2019. As a result of the parent/subsidiary relationship between Dow Inc. and TDCC, and considering that the financial statements and disclosures of each company are substantially similar, the companies are filing a combined report for this Annual Report on Form 10-K. The information reflected in the report is equally applicable to both Dow Inc. and TDCC, except where otherwise noted. As of the effective date and time of the distribution, DowDuPont no longer beneficially owned any equity interest in Dow and no longer consolidated Dow and its consolidated subsidiaries into its financial results. The consolidated financial results of Dow for the applicable periods presented reflect the distribution of TDCC’s agricultural sciences business (“AgCo”) and specialty products business (“SpecCo”) as discontinued operations, as well as the receipt of Historical DuPont’s ethylene and ethylene copolymers businesses (other than its ethylene acrylic elastomers business) (“ECP”) as a common control transaction from the closing of the Merger on August 31, 2017 ("Merger Date"). See Note 3 for additional information. The Company conducts its worldwide operations through six global businesses which are organized into the following operating segments: Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure and Performance Materials & Coatings. Corporate contains the reconciliation between the totals for the operating segments and the Company's totals. See Note 26 for additional information. From the Merger Date through the separation, transactions between DowDuPont, TDCC and Historical DuPont and their affiliates were treated as related party transactions. Transactions between TDCC and Historical DuPont primarily consisted of the sale and procurement of certain raw materials that were consumed in each company's manufacturing process. Transactions between TDCC and Dow Inc. are treated as related party transactions for TDCC. See Note 25 for additional information. Throughout this Annual Report on Form 10-K, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. Except as otherwise indicated by the context, the term "Union Carbide" means Union Carbide Corporation and the term "Dow Silicones" means Dow Silicones Corporation, both wholly owned subsidiaries of the Company. Certain reclassifications of prior period amounts have been made to conform with the current year presentation. Use of Estimates in Financial Statement Preparation The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates. Significant Accounting Policies Asbestos-Related Matters Accruals for asbestos-related matters, including defense and processing costs, are recorded based on an analysis of claim and resolution activity, defense spending, and pending and future claims. These accruals are assessed at each balance sheet date to determine if the asbestos-related liability remains appropriate. Accruals for asbestos-related matters are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent.” See Note 16 for additional information. Legal Costs The Company expenses legal costs as incurred, with the exception of defense and processing costs associated with asbestos-related matters. Foreign Currency Translation The local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in "Accumulated other comprehensive loss" ("AOCL"). For certain subsidiaries, the U.S. dollar is used as the functional currency. This occurs when the subsidiary operates in an economic environment where the products produced and sold are tied to U.S. dollar-denominated markets, or when the foreign subsidiary operates in a hyper-inflationary environment. Where the U.S. dollar is used as the functional currency, foreign currency translation gains and losses are reflected in income. Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Other noncurrent obligations” at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets in “Accounts and notes receivable - Other” or "Noncurrent receivables." Environmental costs are capitalized if the costs extend the life of the property, increase its capacity and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable. Cash and Cash Equivalents Cash and cash equivalents include time deposits and investments with maturities of three months or less at the time of purchase. Financial Instruments The Company calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows. The Company utilizes derivatives to manage exposures to foreign currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair values of these instruments are reported in income or AOCL, depending on the use of the derivative and whether the Company has elected hedge accounting treatment. Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCL until the underlying transactions are recognized in income. Gains and losses on derivative and non-derivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCL as part of the cumulative translation adjustment. Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income. Inventories Inventories are stated at the lower of cost or net realizable value. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year. At December 31, 2021, approximately 27 percent, 65 percent and 8 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively. At December 31, 2020, approximately 30 percent, 58 percent and 12 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively. The Company routinely exchanges and swaps raw materials and finished goods with other companies to reduce delivery time, freight and other transportation costs. These transactions are treated as non-monetary exchanges and are valued at cost. Property Land, buildings and equipment are carried at cost less accumulated depreciation or amortization. Property under finance lease agreements is carried at the present value of lease payments over the lease term less accumulated amortization. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income. Impairment and Disposal of Long-Lived Assets The Company evaluates long-lived assets (property, finite-lived intangible assets and right-of-use assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation/amortization is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value, and depreciation/amortization is recognized over the remaining useful life of the assets. Goodwill and Other Intangible Assets The Company records goodwill when the purchase price of a business combination exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually in the fourth quarter, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. When testing goodwill for impairment, the Company may first assess qualitative factors. If an initial qualitative assessment identifies that it is more likely than not that the fair value of a reporting unit is less than its carrying value, additional quantitative testing is performed. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, an impairment charge is recognized based on the difference between the reporting unit's carrying value and its fair value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units. Finite-lived intangible assets such as developed technology, customer-related, trademarks, tradenames and software, are amortized over their estimated useful lives, generally on a straight-line basis for periods ranging primarily from 3 to 20 years. Asset Retirement Obligations The Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less. Investments Investments in debt securities, primarily held by the Company's insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCL. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by FIFO or specific identification. Investments in equity securities with a readily determinable fair value are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Equity securities without a readily determinable fair value are accounted for at cost, adjusted for impairments and observable price changes in orderly transactions. The Company routinely reviews its investments for declines in fair value below the cost basis. When events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down, establishing a new cost basis. Leases The Company determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating lease right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses the incremental borrowing rate in determining the present value of lease payments, unless the implicit rate is readily determinable. If lease terms include options to extend or terminate the lease, the ROU asset and lease liability are measured based on the reasonably certain decision. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for nearly all classes of leased assets for which the Company is the lessee. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the consolidated statements of income, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. Some leasing arrangements require variable payments that are dependent upon usage or output, or may vary for other reasons, such as insurance or tax payments. Variable lease payments are recognized as incurred and are not presented as part of the ROU asset or lease liability. See Note 17 for additional information. Revenue The Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 for additional information. Revenue related to the Company's insurance operations includes third-party insurance premiums, which are earned over the terms of the related insurance policies and reinsurance contracts. Severance Costs The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic regions. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under the Company’s ongoing benefit arrangements. These severance costs are accrued once management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated. Integration and Separation Costs The Company classifies expenses related to the Merger and separation as "Integration and separation costs" in the consolidated statements of income. Merger and separation related costs include: post-Merger integration expenses, costs incurred for the separation of AgCo and SpecCo and costs related to the integration of ECP. Integration and separation costs primarily consist of financial adviser, information technology, legal, accounting, consulting and other professional advisory fees associated with preparation and execution of these activities. Integration and separation costs related to the Merger and separation were completed as of December 31, 2020. Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The Company uses the portfolio approach for releasing income tax effects from AOCL. The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in “Income taxes payable” and the long-term portion is included in “Other noncurrent obligations” in the consolidated balance sheets. Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested. Earnings per Common Share The calculation of earnings per common share is based on the weighted-average number of the Company's common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive. Adoption of Accounting Standards Effective January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, “Leases (Topic 842),” and the associated ASUs (collectively, "Topic 842") and added the accounting policy on leases discussed in the section above. Adoption of the new standard resulted in the recording of operating lease ROU assets and lease liabilities of $2.3 billion at January 1, 2019. The net impact to “Retained earnings” was an increase of $32 million and was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction. The impact is reflected in the "Adoption of accounting standards" line in the consolidated statements of equity of both Dow Inc. and TDCC. See Note 17 for additional information. In addition, the consolidated financial statements reflect the impact of the adoption of ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," and the associated ASUs (collectively, "Topic 606") at January 1, 2019 by certain nonconsolidated affiliates of the Company, which were subsequently distributed as part of the separation from DowDuPont. The net impact was reflected in assets and liabilities of discontinued operations with a corresponding reduction to "Retained earnings" of $183 million in the consolidated balance sheets at January 1, 2019. The impact is reflected in the "Adoption of accounting standards" line in the consolidated statements of equity of both Dow Inc. and TDCC. TDCC Dividends

SEPARATION FROM DOWDUPONT SEPAR

SEPARATION FROM DOWDUPONT SEPARATION FROM DOWDUPONT (Notes)	12 Months Ended

Discontinued Operations and Disposal Groups [Abstract]
Separation from DowDuPont [Text Block]	SEPARATION FROM DOWDUPONT Effective August 31, 2017, TDCC and Historical DuPont completed the merger of equals transaction contemplated by the Merger Agreement, by and among TDCC, Historical DuPont, DowDuPont, Diamond Merger Sub, Inc. and Orion Merger Sub, Inc. Pursuant to the Merger Agreement, (i) Diamond Merger Sub, Inc. was merged with and into TDCC, with TDCC surviving the merger as a subsidiary of DowDuPont (the "Diamond Merger") and (ii) Orion Merger Sub, Inc. was merged with and into Historical DuPont, with Historical DuPont surviving the merger as a subsidiary of DowDuPont (the "Orion Merger" and, together with the Diamond Merger, the "Mergers"). Following the consummation of the Mergers, each of TDCC and Historical DuPont became subsidiaries of DowDuPont. Subsequent to the Merger, TDCC and Historical DuPont engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products. Dow Inc. was formed as a wholly owned subsidiary of DowDuPont to serve as the holding company for the materials science business. On April 1, 2019, DowDuPont completed the previously announced separation of its materials science business. The separation was effected by way of a pro rata distribution of all of the then-issued and outstanding shares of Dow Inc. common stock to DowDuPont stockholders of record as of the close of business, Eastern Time, on March 21, 2019 (the “Record Date”). The shareholders of record of DowDuPont received one share of Dow Inc. common stock, par value $0.01 per share, for every three shares of DowDuPont common stock, par value $0.01 per share, held as of the Record Date. No fractional shares of Dow Inc. common stock were issued. Instead, cash in lieu of any fractional shares was paid to DowDuPont registered shareholders. The number of shares of Dow Inc. common stock issued on April 1, 2019 was 748.8 million shares. Dow Inc. is now an independent, publicly traded company and Dow Inc. common stock is listed on the NYSE under the symbol “DOW.” Dow Inc. common stock began regular-way trading on April 2, 2019, the first day following the distribution. Effective April 1, 2019, TDCC became a wholly owned subsidiary of Dow Inc. As of the effective date and time of the distribution, DowDuPont did not beneficially own any equity interest in Dow and no longer consolidated Dow and its consolidated subsidiaries into its financial results. Beginning in the second quarter of 2019, Dow’s consolidated financial results reflect the results of Dow Inc. and its consolidated subsidiaries - that is, TDCC after giving effect to the distribution of AgCo and SpecCo and the receipt of ECP. The consolidated financial results of Dow for periods prior to April 1, 2019, reflect the distribution of AgCo and SpecCo as discontinued operations for each period presented as well as reflect the receipt of ECP as a common control transaction from the closing of the Merger on August 31, 2017. On April 1, 2019, Dow Inc. received a cash contribution of $2,024 million from DowDuPont as part of the internal reorganization and business realignment steps between Dow Inc., TDCC and DowDuPont. Dow Inc. recognized a reduction to "Retained earnings" of $14,806 million in 2019 as a result of the cash contribution, the distribution of AgCo and SpecCo, and other separation related adjustments. TDCC recognized a reduction to "Retained earnings" of $16,009 million in 2019 as a result of the distribution of AgCo and SpecCo. Receipt of ECP As the receipt of ECP was accounted for as a transfer between entities under common control, the consolidated financial statements have been retrospectively adjusted to reflect the receipt of ECP from the closing of the Merger on August 31, 2017. All intercompany transactions have been eliminated in consolidation. Distribution of AgCo and SpecCo Upon distribution, the Company retrospectively adjusted the previously issued consolidated financial statements and presented AgCo and SpecCo as discontinued operations based on the guidance in ASC 205-20 “Discontinued Operations” (“ASC 205-20”). The results of operations of AgCo and SpecCo are presented as discontinued operations in the consolidated statements of income and are summarized in the following table: Results of Operations of AgCo and SpecCo 2019 1 In millions Net sales $ 2,953 Cost of sales 1,804 Research and development expenses 175 Selling, general and administrative expenses 262 Amortization of intangibles 61 Restructuring and asset related charges - net 78 Equity in earnings of nonconsolidated affiliates 28 Sundry income (expense) - net (18) Interest income 3 Interest expense and amortization of debt discount 7 Income from discontinued operations before income taxes $ 579 Provision for income taxes 134 Income from discontinued operations, net of tax $ 445 1. Results through March 31, 2019. Agreements Related to the Separation and Distribution In connection with the separation, Dow Inc. entered into certain agreements with DuPont and/or Corteva, Inc. ("Corteva"), including the following: Separation and Distribution Agreement, Tax Matters Agreement and Employee Matters Agreement (collectively, the "Agreements"). In addition to establishing the terms of the separation, the Agreements provide a framework for Dow’s interaction with DuPont and Corteva after the separation and also provide for the allocation among Dow, DuPont and Corteva of assets, liabilities and obligations attributable to periods prior to, at and after the completion of the separation. The Agreements also contain certain indemnity and/or cross-indemnity provisions that are intended to set forth each party’s respective rights, responsibilities and obligations for matters subject to indemnification. Except in certain instances, the parties’ indemnification obligations are uncapped. Certain indemnification obligations will be subject to reduction by insurance proceeds or other third-party proceeds of the indemnified party that reduces the amount of the loss. In addition, indemnifiable losses will be subject to, in certain cases, “de minimis” threshold amounts and, in certain cases, deductible amounts. The impacts of indemnifications and other post-separation matters relating to the Agreements are primarily reflected in the consolidated financial statements of Dow Inc. In 2019, the Company recorded pretax charges related to the Agreements of $69 million in "Sundry income (expense) - net" and $24 million in "Integration and separation costs" in the consolidated statements of income of Dow Inc., related to Corporate. At December 31, 2021, the Company had no assets ($77 million at December 31, 2020) included in "Other current assets" and $20 million ($33 million at December 31, 2020) included in "Noncurrent receivables" and liabilities of $148 million ($412 million at December 31, 2020) included in "Accrued and other current liabilities" and $39 million ($46 million at December 31, 2020) included in "Other noncurrent obligations" in the consolidated balance sheets of Dow Inc. Any adjustments to these assets and liabilities in subsequent periods will be recorded in Dow Inc.'s results of operations. In addition, the Company deferred approximately $400 million of the cash distribution received from DowDuPont at separation and recorded an associated liability with an offset to "Retained earnings" in the consolidated balance sheets of Dow Inc. At December 31, 2021, $15 million ($103 million at December 31, 2020) of this liability was recorded in "Accrued and other current liabilities" and $96 million ($96 million at December 31, 2020) was recorded in "Other noncurrent obligations" in the consolidated balance sheets of Dow Inc. In the fourth quarter of 2021, due to changes in certain underlying exposures, Dow Inc. reversed $46 million of the liability. Based on notices received in the fourth quarter of 2020, Dow Inc. reversed $177 million of the liability. The impact of the reversals are reflected in the "Common control transaction" line in the consolidated statements of equity of Dow Inc. The final resolution of the remaining liability is uncertain and any subsequent adjustments to the carrying value of this liability will be reflected in equity of Dow Inc. In 2021, Dow Inc. made net cash payments of $60 million ($18 million in 2020 and $215 million in 2019) related to the Agreements, recorded in "Cash flows from operating activities - discontinued operations" in the Dow Inc. consolidated statements of cash flows. The Company also received $144 million in 2021 (insignificant in 2020 and $98 million in 2019) related to the Agreements, recorded in "Other assets and liabilities, net" within "Cash flows from operating activities - continuing operations" in the Dow Inc. consolidated statements of cash flows. Continuing Involvement The Company has certain product and service agreements with DuPont and Corteva that were considered intercompany transactions prior to the separation, but are trade transactions subsequent to the separation. These transactions have been retrospectively reclassified as trade transactions in the consolidated financial statements. Based on the Company’s assessment of the specific factors identified in ASC Topic 205, “Presentation of Financial Statements,” the Company concluded that these agreements do not constitute significant continuing involvement in AgCo or SpecCo. Integration and Separation Costs Integration and separation costs, which reflect costs related to post-Merger integration and business separation activities, were $239 million in 2020 and $1,063 million and $1,039 million for Dow Inc. and TDCC, respectively, in 2019. Integration and separation costs related to post-Merger integration and business separation activities were completed as of December 31, 2020.

REVENUE (Notes)

REVENUE (Notes)	12 Months Ended
	Dec. 31, 2021
Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE The majority of the Company's revenue is derived from product sales. In 2021, 99 percent of the Company's revenue related to product sales (99 percent in 2020 and 98 percent in 2019). The remaining sales were primarily related to the Company's insurance operations and licensing of patents and technologies. Product Sales Product sales consist of sales of the Company's products to manufacturers and distributors. The Company considers order confirmations or purchase orders, which in some cases are governed by master supply agreements, to be contracts with a customer. Product sale contracts are generally short-term contracts where the time between order confirmation and satisfaction of all performance obligations is less than one year. However, the Company has some long-term contracts which can span multiple years. Revenues from product sales are recognized when the customer obtains control of the product, which occurs at a point in time, usually upon shipment, with payment terms typically in the range of 30 to 60 days after invoicing, depending on business and geographic region. When the Company performs shipping and handling activities after the transfer of control to the customer (e.g., when control transfers prior to shipment), these are considered fulfillment activities, and accordingly, the costs are accrued when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. The Company elected to use the practical expedient to expense cash and non-cash sales incentives, as the amortization period for the costs to obtain the contract would have been one year or less. Certain long-term contracts include a series of distinct goods that are delivered continuously to the customer through a pipeline (e.g., feedstocks). For these types of product sales, the Company invoices the customer in an amount that directly corresponds with the value to the customer of the Company’s performance to date. As a result, the Company recognizes revenue based on the amount billable to the customer in accordance with the right to invoice practical expedient. The transaction price includes estimates for reductions in revenue from customer rebates and right of returns on product sales. These amounts are estimated based upon the most likely amount of consideration to which the customer will be entitled. All estimates are based on historical experience, anticipated performance and the Company’s best judgment at the time to the extent it is probable that a significant reversal of revenue recognized will not occur. All estimates for variable consideration are reassessed periodically. The Company elected the practical expedient to not adjust the amount of consideration for the effects of a significant financing component for all instances in which the period between payment and transfer of the goods will be one year or less. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation based on the relative standalone selling price. The standalone selling price is the observable price which depicts the price as if sold to a similar customer in similar circumstances. Patents, Trademarks and Licenses The Company enters into licensing arrangements in which it licenses certain rights of its patents and technology to customers. Revenue from the majority of the Company’s licenses for patents and technology is derived from sales-based royalties. The Company estimates the amount of sales-based royalties it expects to be entitled to based on historical sales to the customer. For the remaining revenue from licensing arrangements, payments are typically received from the Company's licensees based on billing schedules established in each contract. Revenue is recognized when the performance obligation is satisfied. Remaining Performance Obligations Remaining performance obligations represent the transaction price allocated to unsatisfied or partially unsatisfied performance obligations. At December 31, 2021, the Company had unfulfilled performance obligations of $829 million ($977 million at December 31, 2020) related to the licensing of technology and expects revenue to be recognized for the remaining performance obligations over the next six years. The remaining performance obligations are for product sales that have expected durations of one year or less, product sales of materials delivered through a pipeline for which the Company has elected the right to invoice practical expedient, or variable consideration attributable to royalties for licenses of patents and technology. The Company has received advance payments from customers related to long-term supply agreements that are deferred and recognized over the life of the contract, with remaining contract terms that range up to 19 years. The Company will have rights to future consideration for revenue recognized when product is delivered to the customer. These payments are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets. Disaggregation of Revenue Dow disaggregates its revenue from contracts with customers by operating segment and business, as the Company believes it best depicts the nature, amount, timing and uncertainty of its revenue and cash flows.

Europe, Middle East, Africa and India. Contract Assets and Liabilities The Company receives payments from customers based upon contractual billing schedules. Accounts receivable are recorded when the right to consideration becomes unconditional. Contract assets include amounts related to the Company’s contractual right to consideration for completed performance obligations not yet invoiced. Contract liabilities include payments received in advance of performance under the contract and are recognized in revenue when the performance obligations are met. "Contract liabilities - current" primarily reflects deferred revenue from prepayments from customers for product to be delivered in 12 months or less and royalty payments that are deferred and will be recognized in 12 months or less. "Contract liabilities - noncurrent" includes advance payments that the Company has received from customers related to long-term supply agreements and royalty payments that are deferred and recognized over the life of the contract. Revenue recognized in 2021 from amounts included in contract liabilities at the beginning of the period was approximately $295 million (approximately $145 million in 2020 and 2019). In 2021, the amount of contract assets reclassified to receivables as a result of the right to the transaction consideration becoming unconditional was approximately $35 million (approximately $25 million in 2020). The Company did not recognize any asset impairment charges related to contract assets in 2021, 2020 or 2019. The following table summarizes the contract assets and liabilities at December 31, 2021 and 2020: Contract Assets and Liabilities at Dec 31 Balance Sheet Classification 2021 2020 In millions Accounts and notes receivable - trade Accounts and notes receivable - Trade $ 6,841 $ 5,090 Contract assets - current Other current assets $ 34 $ 58 Contract assets - noncurrent Deferred charges and other assets $ 26 $ 11 Contract liabilities - current 1 Accrued and other current liabilities $ 209 $ 349 Contract liabilities - noncurrent Other noncurrent obligations $ 1,925 $ 1,915 1. The decrease from December 31, 2020 to December 31, 2021 was due to recognition of deferred royalty payments.

DIVESTITURES	DIVESTITURES Divestiture of Rail Infrastructure Operations and Assets On September 30, 2020, TDCC sold its rail infrastructure operations and assets, including existing agreements to provide rail services to unrelated third parties, at six sites in the U.S. & Canada to an affiliate of Watco Companies, L.L.C. for cash proceeds of $303 million, net of costs to sell and other adjustments and subject to customary post-closing adjustments. These assets are located at TDCC’s sites in Plaquemine and St. Charles, Louisiana; Freeport and Seadrift, Texas; and Fort Saskatchewan and Prentiss, Alberta, Canada. Divested operations included property with a net book value of $68 million and goodwill of $2 million ($16 million related to Packaging & Specialty Plastics and $54 million related to Corporate). TDCC retained ownership of the sites and underlying real property where the divested operations are located. TDCC and the buyer entered into mutual long-term service agreements designed to ensure the continuation of rail services for TDCC's existing operations at each site. The rail-service agreements include variable fees that have an initial term of 25 years. TDCC recognized a pretax gain of $233 million on the sale ($48 million related to Packaging & Specialty Plastics and $185 million related to Corporate), included in "Sundry income (expense) - net" in the consolidated statements of income. The Company evaluated the divestiture of the rail infrastructure operations and assets and determined it did not represent a strategic shift that had a major effect on the Company’s operations and financial results and did not qualify as an individually significant component of the Company. As a result, the divestiture is not reported as discontinued operations. Divestiture of Marine and Terminal Operations and Assets On December 1, 2020, TDCC sold certain U.S. Gulf Coast marine and terminal operations and assets, including existing agreements to provide marine and terminal services to unrelated third parties, at three U.S. sites to an affiliate of Royal Vopak for cash proceeds of $600 million, net of costs to sell and other adjustments and subject to customary post-closing adjustments. These assets are located at TDCC's sites in Plaquemine and St. Charles, Louisiana, and Freeport, Texas. Divested operations included property with a net book value of $93 million and goodwill of $8 million ($7 million related to Packaging & Specialty Plastics, $17 million related to Industrial Intermediates & Infrastructure and $77 million related to Corporate). TDCC retained ownership of the sites and the underlying real property where the divested operations are located. TDCC and the buyer entered into mutual long-term service agreements designed to ensure the continuation of marine and terminal services for TDCC's existing operations at each site. The marine and terminal service agreements include fixed and variable fees that have initial terms of up to 25 years. In the fourth quarter of 2020, TDCC recognized a pretax gain of $499 million on the sale ($17 million related to Packaging & Specialty Plastics, $61 million related to Industrial Intermediates & Infrastructure and $421 million related to Corporate), included in "Sundry income (expense) - net" in the consolidated statements of income. The Company evaluated the divestiture of the marine and terminal operations and assets and determined it did not represent a strategic shift that had a major effect on the Company’s operations and financial results and did not qualify as an individually significant component of the Company. As a result, the divestiture is not reported as discontinued operations.

Restructuring and Related Activities [Abstract]
RESTRUCTURING, GOODWILL IMPAIRMENT AND ASSET RELATED CHARGES - NET	RESTRUCTURING, GOODWILL IMPAIRMENT AND ASSET RELATED CHARGES - NET The "Restructuring, goodwill impairment and asset related charges - net" line in the consolidated statements of income is used to record charges for restructuring programs, goodwill impairments, and other asset related charges, which includes other asset impairments. Restructuring Programs 2020 Restructuring Program On September 29, 2020, the Board of Dow Inc. approved restructuring actions to achieve the Company's structural cost improvement initiatives in response to the continued economic impact from the coronavirus disease 2019 ("COVID-19") pandemic. The restructuring program was designed to reduce structural costs and enable the Company to further enhance competitiveness while the COVID-19 economic recovery gained traction. This program included a global workforce cost reduction of approximately 6 percent and actions to rationalize the Company's manufacturing assets, which included asset write-down and write-off charges, related contract termination fees and environmental remediation costs ("2020 Restructuring Program"). Severance benefits are provided to employees primarily under Dow's ongoing benefit arrangements and are accrued against the Corporate segment once management commits to a plan of termination. The actions related to the 2020 Restructuring Program were substantially complete by the end of 2021, except for certain cash payments expected to be made in 2022. In the third quarter of 2020, the Company recorded pretax restructuring charges of $575 million, consisting of severance and related benefit costs of $297 million, asset write-downs and write-offs of $197 million and costs associated with exit and disposal activities of $81 million. In the fourth quarter of 2020, the Company recorded net favorable pretax restructuring credits of $1 million related to asset write-downs and write-offs and $1 million related to costs associated with exit and disposal activities (related to Performance Materials & Coatings and Corporate). The adjustment to costs associated with exit and disposal activities included curtailment costs associated with a defined benefit pension plan. See Note 20 for additional information. In 2021, the Company recorded pretax restructuring charges of $12 million for asset write-downs and write-offs and $10 million for costs associated with exit and disposal activities. In addition, the Company reduced pretax restructuring charges by $10 million for severance and related benefit costs.

Asset Write-downs and Write-offs The 2020 Restructuring Program included charges related to the write-down and write-off of assets totaling $196 million in 2020. Details regarding the asset write-downs and write-offs are as follows: • Packaging & Specialty Plastics recorded a charge of $11 million to rationalize its production capacity by shutting down a small-scale production unit. • Industrial Intermediates & Infrastructure recorded a charge of $22 million to rationalize its asset footprint by shutting down certain amines and solvents facilities in the United States and Europe as well as select, small-scale downstream polyurethanes manufacturing facilities. • Performance Materials & Coatings recorded a charge of $116 million to shut down manufacturing assets, primarily related to small-scale coatings reactors, and will also rationalize its upstream asset footprint in Europe and the U.S. & Canada by adjusting the supply of siloxane and silicon metal to balance to regional needs. • Corporate recorded a charge of $47 million related to the write-down of leased, non-manufacturing facilities and the write-down of miscellaneous assets. The 2020 Restructuring Program included charges related to the write-down and write-off of assets totaling $12 million in 2021, which included additional write-down and write-off of assets related to the actions listed above, impacting Industrial Intermediates & Infrastructure ($1 million) and Performance Materials & Coatings ($8 million), and the write-down of an additional non-manufacturing facility impacting Corporate ($3 million). Shut down related activities for impacted facilities were substantially complete by the end of 2021. Costs Associated with Exit and Disposal Activities The 2020 Restructuring Program included charges of $80 million for costs associated with exit and disposal activities in 2020, which included $19 million for contract termination fees related to the asset actions listed above, impacting Performance Materials & Coatings ($9 million) and Corporate ($10 million), as well as $56 million for environmental remediation, impacting Performance Materials & Coatings ($52 million) and Corporate ($4 million) and $5 million related to curtailment costs associated with a defined benefit pension plan, impacting Corporate. The 2020 Restructuring Program included charges of $10 million for costs associated with exit and disposal activities in 2021, which included contract termination fees and environmental remediation, impacting Packaging & Specialty Plastics ($8 million) and Performance Materials & Coatings ($2 million). DowDuPont Cost Synergy Program In September and November 2017, DowDuPont approved post-Merger restructuring actions under the DowDuPont Cost Synergy Program (the "Synergy Program") which was designed to integrate and optimize the organization following the Merger and in preparation for the business separations. The Company expected (prior to the impact of any discontinued operations) to record total pretax restructuring charges of approximately $1.3 billion, which included initial estimates of approximately $525 million to $575 million of severance and related benefit costs, $400 million to $440 million of asset write-downs and write-offs, and $290 million to $310 million of costs associated with exit and disposal activities. The restructuring charges below reflect charges from continuing operations. The Company recorded pretax restructuring charges of $292 million in 2019, consisting of severance and related benefit costs of $123 million, assets write-downs and write-offs of $143 million and costs associated with exit and disposal activities of $26 million. In 2020, the Company recorded pretax restructuring charges of $86 million and reduced pretax restructuring charges by $6 million in 2021, both for severance and related benefit costs. Cash expenditures related to the Synergy Program were substantially complete at December 31, 2020. At December 31, 2021, $4 million was included in "Accrued and other current liabilities" ($21 million at December 31, 2020) and $10 million ($13 million at December 31, 2020) was included in "Other noncurrent obligations" in the consolidated balance sheets. The Company recorded pretax restructuring charges of $955 million inception-to-date under the Synergy Program on a continuing operations basis, consisting of severance and related benefit costs of $647 million, asset write-downs and write-offs of $263 million and costs associated with exit and disposal activities of $45 million. Asset Write-downs and Write-offs The restructuring charges related to the write-down and write-off of assets in 2019 under the Synergy Program were as follows: • The Company recorded a charge of $143 million for other miscellaneous asset write-downs and write-offs, including the shutdown of several small manufacturing facilities and the write-off of non-manufacturing assets and certain corporate facilities. The charge related to Industrial Intermediates & Infrastructure ($2 million), Performance Materials & Coatings ($28 million) and Corporate ($113 million). These manufacturing facilities were substantially shut down by the end of 2020. There were no restructuring charges related to the write-down and write-off of assets in 2020 and 2021 under the Synergy Program. Costs Associated with Exit and Disposal Activities The restructuring charges for costs associated with exit and disposal activities, including contract cancellation penalties and environmental remediation liabilities, totaled $26 million in 2019 and zero in 2020 and 2021. The Company expects to incur additional costs in the future related to its restructuring activities. Future costs are expected to include demolition costs related to closed facilities and restructuring implementation costs. These costs will be recognized as incurred. The Company also expects to incur additional employee-related costs, including involuntary termination benefits, related to its other optimization activities. These costs cannot be reasonably estimated at this time. 2019 Goodwill Impairment Upon completion of the goodwill impairment testing in the fourth quarter of 2019, the Company determined the fair value of the Coatings & Performance Monomers reporting unit was lower than its carrying amount. As a result, the Company recorded an impairment charge of $1,039 million in the fourth quarter of 2019, related to Performance Materials & Coatings. See Note 13 for additional information. Asset Related Charges 2020 Charges In 2020, the Company recognized pretax impairment charges of $49 million, including additional pretax impairment charges for capital additions made to a bio-ethanol manufacturing facility in Santa Vitoria, Minas Gerais, Brazil ("Santa Vitoria"), which was impaired in 2017 and divested in 2020, as well as charges for miscellaneous write-offs and write-downs of non-manufacturing assets and the write-down of certain corporate leased equipment. The impairment charges related to Packaging & Specialty Plastics ($19 million), Performance Materials & Coatings ($15 million) and Corporate ($15 million). See Note 23 for additional information. 2019 Charges On August 13, 2019, the Company entered into a definitive agreement to sell its acetone derivatives business to ALTIVIA Ketones & Additives, LLC. The transaction closed on November 1, 2019 and included the Company's acetone derivatives related inventory and production assets, located in Institute, West Virginia, in addition to the site infrastructure, land, utilities and certain railcars. The Company remains at the Institute site as a tenant. As a result of the planned transaction, the Company recognized a pretax impairment charge of $75 million in the third quarter of 2019, related to Packaging & Specialty Plastics ($24 million) and Corporate ($51 million). See Note 23 for additional information. In the fourth quarter of 2019, upon completion of an evaluation of its equity method investment in Sadara Chemical Company ("Sadara") for other-than-temporary impairment, the Company determined that its investment in Sadara was other-than-temporarily impaired and it was written down to zero. Additionally, as part of Dow's evaluation of Sadara, the Company reserved certain of its notes and accounts receivable with Sadara due to uncertainty on the timing of collection. As a result, the Company recorded a $1,755 million charge, related to Packaging & Specialty Plastics ($370 million), Industrial Intermediates & Infrastructure ($1,168 million) and Corporate ($217 million). See Notes 12 and 23 for additional information.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The financial statements for Dow Inc. and TDCC are substantially similar, including the reporting of current and deferred tax expense (benefit), provision for income taxes on continuing operations, and deferred tax asset and liability balances. As a result, the following income tax discussion pertains to Dow Inc. only. Geographic Allocation of Income and Provision for Income Taxes on Continuing Operations In millions 2021 2020 2019 Income (loss) from continuing operations before income taxes Domestic 1 $ 1,523 $ (681) $ (1,196) Foreign 2 6,622 2,752 (51) Income (loss) from continuing operations before income taxes $ 8,145 $ 2,071 $ (1,247) Current tax expense (benefit) Federal $ (46) $ (176) $ (287) State and local 48 4 25 Foreign 1,460 691 960 Total current tax expense $ 1,462 $ 519 $ 698 Deferred tax expense (benefit) Federal $ 130 $ 184 $ 52 State and local 26 19 19 Foreign 122 55 (299) Total deferred tax expense (benefit) $ 278 $ 258 $ (228) Provision for income taxes on continuing operations $ 1,740 $ 777 $ 470 Income (loss) from continuing operations, net of tax $ 6,405 $ 1,294 $ (1,717) 1. The 2019 amount includes approximately $1.4 billion of expense related to goodwill impairment and environmental matters. See Notes 13 and 16 for additional information. 2. The 2019 amount includes approximately $1.8 billion of expense for Sadara related charges. See Note 12 for additional information.

See Note 6 for additional information. 3. Includes the impact of tax reform in Switzerland and the United States. 4. The 2021 impact represents a capital loss incurred on an internal restructuring fully offset by a valuation allowance reported in "Changes in valuation allowances" line item. The 2019 impact primarily relates to the favorable impact of the restoration of tax basis in assets, driven by a court judgment that did not involve the Company. 5. See Note 12 for additional information. 6. See Note 13 for additional information. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted on March 27, 2020 in the United States. While the CARES Act had no significant impact on the Company's provision for income taxes on continuing operations in 2020, the Company filed a tax loss carryback claim for $291 million in accordance with the provisions of the CARES Act in 2020. This resulted in an increase in "Accounts and notes receivable - other" and a decrease in "Deferred income tax assets" in the consolidated balance sheets. In 2021, the Company received $247 million of the tax loss carryback claim with the residual balance expected to be received in 2022. In the fourth quarter of 2020, a valuation allowance of $260 million was recorded in the United States, primarily due to filing of the final combined Dow and DuPont tax return and related unutilized foreign tax credits. In 2021, the Company's strong earnings and revised projections resulted in a reversal of the valuation allowance.

Undistributed earnings are subject to certain taxes upon repatriation, primarily where foreign withholding taxes apply. It is not practicable to calculate the unrecognized deferred tax liability on undistributed earnings. Prior to the separation, TDCC and its consolidated subsidiaries were included in DowDuPont's consolidated federal income tax group and consolidated tax return. Generally, the consolidated tax liability of the DowDuPont U.S. tax group for each year was apportioned among the members of the consolidated group based on each member’s separate taxable income. TDCC and DuPont intend that, to the extent federal and/or state corporate income tax liabilities are reduced through the utilization of tax attributes of the other, settlement of any receivable and payable generated from the use of the other party’s sub-group attributes will be in accordance with a tax sharing agreement and/or tax matters agreement. At December 31, 2021, the Company had a receivable of zero related to the tax sharing agreement ($261 million at December 31, 2020), included in "Other current assets" in the consolidated balance sheets. Balances related to the tax matters agreement are further discussed in Note 3. The following table provides a reconciliation of the Company's unrecognized tax benefits: Total Gross Unrecognized Tax Benefits In millions 2021 2020 2019 Total unrecognized tax benefits at Jan 1 $ 373 $ 319 $ 314 Decreases related to positions taken on items from prior years (3) (1) (1) Increases related to positions taken on items from prior years 187 52 16 Increases related to positions taken in the current year 44 18 10 Settlement of uncertain tax positions with tax authorities (18) (14) (19) Decreases due to expiration of statutes of limitations (1) (1) — Foreign exchange gain (2) — (1) Total unrecognized tax benefits at Dec 31 $ 580 $ 373 $ 319 Total unrecognized tax benefits that, if recognized, would impact the effective tax rate $ 501 $ 285 $ 234 Total amount of interest and penalties expense (benefit) recognized in "Provision for income taxes on continuing operations" $ 359 $ 84 $ (11) Total accrual for interest and penalties recognized in the consolidated balance sheets $ 502 $ 144 $ 100 The 2021 impacts primarily relate to an increase in uncertain tax positions due to controversy in multiple jurisdictions related to various prior year cross-border matters. The Company files tax returns in the multiple jurisdictions. These returns are subject to examination and possible challenge by the tax authorities. Open tax years are indicated in the table below. Tax Years Subject to Examination by Major Tax Jurisdiction at Dec 31, 2021 Earliest Open Year Jurisdiction Argentina 2014 Brazil 2015 Canada 2012 China 2011 Germany 2014 Italy 2016 The Netherlands 2019 Switzerland 2016 United States: Federal income tax 2007 State and local income tax 2004 Open years contain matters that could be subject to differing interpretations of applicable tax laws and regulations as they relate to the amount, character, timing or inclusion of revenue and expenses or the sustainability of income tax credits for a given audit cycle. The ultimate resolution of such uncertainties is not expected to have a material impact on the Company's results of operations.

Restricted stock units are considered participating securities due to the Company's practice of paying dividend equivalents on unvested shares. 2. The year ended December 31, 2019 reflected a loss from continuing operations, and as such, the basic share count was used for purposes of calculating earnings per share on a diluted basis. 3. These outstanding options to purchase shares of common stock and restricted stock units were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive.

Except for AFSI, the nonconsolidated affiliates in which the Company has investments are privately held companies; therefore, quoted market prices are not available. Sadara In 2011, the Company and Saudi Arabian Oil Company formed Sadara - a joint venture between the two companies that subsequently constructed and now operates a world-scale, fully integrated chemicals complex in Jubail Industrial City, Kingdom of Saudi Arabia. The Company has a 35 percent equity interest in this joint venture and has been, and continues to be, responsible for marketing the majority of Sadara’s products through the Company’s established sales channels. In 2021, Dow and the Saudi Arabian Oil Company agreed to and began transitioning the marketing rights and responsibilities for Sadara’s finished products to levels more consistent with each partner’s equity ownership. The Company’s investment in Sadara was $1,541 million less than Dow’s proportionate share of the carrying value of the underlying net assets held by Sadara at December 31, 2021 ($1,618 million less at December 31, 2020). This basis difference is primarily attributed to the long-lived assets of Sadara and is being amortized over the remaining useful lives of the assets. At December 31, 2021, the Company had an investment balance in Sadara of $416 million included in “Investment in nonconsolidated affiliates” (negative $22 million at December 31, 2020 included in “Other noncurrent obligations”) in the Company’s consolidated balance sheets. See Note 16 for additional information related to guarantees. In 2019, the Company recorded impairment charges related to its investment in Sadara. The joint venture achieved full commercial operations of all its facilities in 2017. In December 2018, the joint venture successfully completed its Creditors Reliability Test, an extensive operational testing program designed to demonstrate the reliability of the joint venture’s full chemical complex by operating at high rates for an extended period of time. While Sadara had reached these operational milestones and had been generating positive EBITDA (a non-GAAP measure defined as earnings before interest, taxes, depreciation and amortization), the joint venture had yet to report positive net income. During the fourth quarter of 2019, Sadara tested its long-lived assets for impairment using long-term cash flow projections. Sadara’s U.S. GAAP impairment test utilized an undiscounted cash flow methodology, under which Sadara concluded its long-lived assets were recoverable. Due to Sadara's financial condition and its long-lived asset impairment test, Dow evaluated its equity method investment in Sadara for other-than-temporary impairment. The Company utilized a discounted cash flow methodology to measure the estimated fair value of its investment in Sadara, which was estimated to be zero (see Note 23 for additional information on the fair value measurement). The Company determined the decline in value of its investment in Sadara was other-than-temporary due to Sadara’s financial performance since becoming commercially operational in 2017 and uncertainty around prospects for recovery in Sadara’s financial condition. In addition, the Company reserved certain accounts and notes receivable and accrued interest balances associated with Sadara due to uncertainty around the timing of collection. In total, the Company recorded a $1,755 million pretax charge in the fourth quarter of 2019 related to Sadara, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income and related to Packaging & Specialty Plastics ($370 million), Industrial Intermediates & Infrastructure ($1,168 million) and Corporate ($217 million). In 2020, the Company loaned $333 million to Sadara that was accounted for as in substance common stock and classified as "Investment in nonconsolidated affiliates" in the Company's consolidated balance sheets. The Company loaned $473 million to Sadara and converted $380 million of the notes and accounts receivable into equity during 2019. At December 31, 2021 and 2020, the Company's note receivable with Sadara was zero. EQUATE At December 31, 2021, the Company had an investment balance in EQUATE of $115 million included in “Investment in nonconsolidated affiliates” (negative $147 million at December 31, 2020 included in "Other noncurrent obligations") in the consolidated balance sheets. The Company's investment in EQUATE was $458 million less than the Company's proportionate share of EQUATE's underlying net assets at December 31, 2021 ($475 million less at December 31, 2020), which represents the difference between the fair values of certain MEGlobal assets acquired by EQUATE and the Company's related valuation on a U.S. GAAP basis. A basis difference of $140 million at December 31, 2021 ($155 million at December 31, 2020) is being amortized over the remaining useful lives of the assets and the remainder is considered a permanent difference. AFSI At December 31, 2021 and 2020, the Company had an investment balance in AFSI of zero. At December 31, 2021, the Company's investment in AFSI was $96 million less than the Company's proportionate share of AFSI's underlying net assets ($108 million less at December 31, 2020). This amount primarily relates to an other-than-temporary decline in the Company's investment in AFSI. At December 31, 2021 and 2020, the Company held a 40 percent ownership interest in AFSI. Transactions with Nonconsolidated Affiliates The Company has service agreements with certain nonconsolidated affiliates, including contracts to manage the operations of manufacturing sites and the construction of new facilities; licensing and technology agreements; and marketing, sales, purchase, lease and sublease agreements. The Company sells excess ethylene glycol produced at manufacturing facilities in the United States and Europe to MEGlobal, a subsidiary of EQUATE. The Company also sells ethylene to MEGlobal as a raw material for its ethylene glycol plants in Canada. Sales of these products to MEGlobal represented 1 percent of total net sales in 2021, 2020 and 2019. Sales of ethylene to MEGlobal are reflected in the Packaging & Specialty Plastics segment and represented 2 percent of the segment's sales in 2021 (2 percent in 2020 and 1 percent in 2019). Sales of ethylene glycol to MEGlobal are reflected in the Industrial Intermediates & Infrastructure segment and represented 1 percent of the segment's sales in 2021, 2020 and 2019. The Company is responsible for marketing the majority of Sadara products outside of the Middle East zone through the Company’s established sales channels. Under this arrangement, the Company purchases and sells Sadara products for a marketing fee. In March 2021, Dow and the Saudi Arabian Oil Company agreed to transition the marketing rights and responsibilities for Sadara’s finished products to levels more consistent with each partner’s equity ownership. This transition began in July 2021 and is being implemented over the next five years. Purchases of Sadara products represented 9 percent of "Cost of sales" in 2021 (8 percent in 2020 and 2019). The Company purchases products from The SCG-Dow Group, primarily for marketing and distribution in Asia Pacific. Purchases of products from The SCG-Dow Group represented 3 percent of "Cost of sales" in 2021 (3 percent in 2020 and 2 percent in 2019). Sales to and purchases from other nonconsolidated affiliates were not material to the consolidated financial statements. Balances due to or due from nonconsolidated affiliates at December 31, 2021 and 2020 were as follows: Balances Due To or Due From Nonconsolidated Affiliates at Dec 31 2021 2020 In millions Accounts and notes receivable - Other $ 357 $ 229 Accounts payable - Other $ 1,611 $ 1,075 Principal Nonconsolidated Affiliates The Company had an ownership interest in 37 nonconsolidated affiliates at December 31, 2021 (35 at December 31, 2020).

GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS The following table shows changes in the carrying amounts of goodwill by reportable segment for the years ended December 31, 2021 and 2020: Goodwill Packaging & Specialty Plastics Industrial Intermediates & Infrastructure Performance Materials & Coatings Total In millions Balance at Jan 1, 2020 $ 5,109 $ 1,100 $ 2,587 $ 8,796 Foreign currency impact 12 4 106 122 Sale of rail infrastructure (2) — — (2) Sale of marine and terminal infrastructure (4) (4) — (8) Balance at Dec 31, 2020 $ 5,115 $ 1,100 $ 2,693 $ 8,908 Foreign currency impact (10) (4) (130) (144) Balance at Dec 31, 2021 $ 5,105 $ 1,096 $ 2,563 $ 8,764 The separation from DowDuPont did not impact the composition of the Company's six reporting units: Coatings & Performance Monomers, Consumer Solutions, Hydrocarbons & Energy, Industrial Solutions, Packaging and Specialty Plastics and Polyurethanes & Construction Chemicals. The ECP businesses received as part of the separation from DowDuPont are included in the Hydrocarbons & Energy and Packaging and Specialty Plastics reporting units. At December 31, 2021, goodwill was carried by all reporting units except Coatings & Performance Monomers (“C&PM”). Goodwill Impairments The carrying amounts of goodwill at December 31, 2021 and 2020 were net of accumulated impairments of $309 million in Industrial Intermediates & Infrastructure and $2,530 million in Performance Materials & Coatings. Goodwill Impairment Testing The Company performs an impairment test of goodwill annually in the fourth quarter. In 2021, the Company performed qualitative testing for all reporting units that carried goodwill. Based on the results of the qualitative testing, the Company did not perform quantitative testing on any reporting units (one in 2020 and two in 2019). The qualitative testing on the reporting units indicated that it was not more likely than not that fair value was less than the carrying value for the reporting units. The quantitative testing conducted in 2020 concluded that no goodwill impairments existed. Upon completion of the quantitative testing in the fourth quarter of 2019, the Company determined the C&PM reporting unit was impaired. During 2019, the C&PM reporting unit did not consistently meet expected financial performance targets, primarily due to the industry’s increased captive use of coatings products, which led to volume reductions; reduced margins for products across the portfolio due to changes in customer buying patterns and supply and demand balances; as well as a continuous trend of customer consolidation in end-markets, which reduced growth opportunities. As a result, the C&PM reporting unit lowered its future revenue and profitability projections. The fair value of the C&PM reporting unit was determined using a discounted cash flow methodology that reflected reductions in projected revenue growth rates due to lower sales volume and price assumptions, as well as reductions to future growth rates. These discounted cash flows did not support the carrying value of the C&PM reporting unit. As a result, the Company recorded a goodwill impairment charge of $1,039 million in the fourth quarter of 2019, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income and related to the Performance Materials & Coatings segment. The carrying value of the C&PM reporting unit's goodwill was zero at December 31, 2019. No other goodwill impairments were identified as a result of the 2019 testing.

While the terms and amounts of letters of credit change, the Company generally has approximately $400 million of outstanding letters of credit at any given time. Debt Covenants and Default Provisions TDCC’s outstanding long-term debt has been issued primarily under indentures which contain, among other provisions, certain customary restrictive covenants with which TDCC must comply while the underlying notes are outstanding. Failure of TDCC to comply with any of its covenants, could result in a default under the applicable indenture and allow the note holders to accelerate the due date of the outstanding principal and accrued interest on the underlying notes. TDCC's indenture covenants include obligations to not allow liens on principal U.S. manufacturing facilities, enter into sale and lease-back transactions with respect to principal U.S. manufacturing facilities, merge or consolidate with any other corporation, or sell, lease or convey, directly or indirectly, all or substantially all of TDCC’s assets. The outstanding debt also contains customary default provisions. TDCC remains in compliance with these covenants. TDCC’s primary, private credit agreements also contain certain customary restrictive covenant and default provisions in addition to the covenants set forth above with respect to TDCC’s debt. Significant other restrictive covenants and default provisions related to these agreements include: (a) the obligation to maintain the ratio of TDCC’s consolidated indebtedness to consolidated capitalization at no greater than 0.70 to 1.00 at any time the aggregate outstanding amount of loans under the Five Year Competitive Advance and Revolving Credit Facility Agreement ("Revolving Credit Agreement") dated November 23, 2021, equals or exceeds $500 million, (b) a default if TDCC or an applicable subsidiary fails to make any payment, including principal, premium or interest, under the applicable agreement on other indebtedness of, or guaranteed by, TDCC or such applicable subsidiary in an aggregate amount of $100 million or more when due, or any other default or other event under the applicable agreement with respect to such indebtedness occurs which permits or results in the acceleration of $400 million or more in the aggregate of principal, and (c) a default if TDCC or any applicable subsidiary fails to discharge or stay within 60 days after the entry of a final judgment against TDCC or such applicable subsidiary of more than $400 million. Failure of TDCC to comply with any of the covenants or default provisions could result in a default under the applicable credit agreement which would allow the lenders to not fund future loan requests and to accelerate the due date of the outstanding principal and accrued interest on any outstanding indebtedness. On April 1, 2019, DowDuPont completed the separation of its materials science business and Dow Inc. became the direct parent company of TDCC. In conjunction with the separation, Dow Inc. is obligated, substantially concurrently with the issuance of any guarantee in respect of outstanding or committed indebtedness under TDCC's Revolving Credit Agreement, to enter into a supplemental indenture with TDCC and the trustee under TDCC’s existing 2008 base indenture governing certain notes issued by TDCC. Under such supplemental indenture, Dow Inc. will guarantee all outstanding debt securities and all amounts due under such existing base indenture and will become subject to certain covenants and events of default under the existing base indenture. In addition, the Revolving Credit Agreement includes an event of default which would be triggered in the event Dow Inc. incurs or guarantees third party indebtedness for borrowed money in excess of $250 million or engages in any material activity or directly owns any material assets, in each case, subject to certain conditions and exceptions. Dow Inc. may, at its option, cure the event of default by delivering an unconditional and irrevocable guarantee to the administrative agent within thirty days of the event or events giving rise to such event of default. No such events have occurred or have been triggered at the time of the filing of this Annual Report on Form 10-K.

At December 31, 2021, the Company had accrued obligations of $1,220 million for probable environmental remediation and restoration costs ($1,244 million at December 31, 2020), including $237 million for the remediation of Superfund sites ($248 million at December 31, 2020). This is management’s best estimate of the costs for remediation and restoration with respect to environmental matters for which the Company has accrued liabilities, although it is reasonably possible that the ultimate cost with respect to these particular matters could range up to approximately two times that amount. Consequently, it is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the Company’s results of operations, financial condition and cash flows. It is the opinion of the Company’s management, however, that the possibility is remote that costs in excess of the range disclosed will have a material impact on the Company’s results of operations, financial condition or cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration. As new or additional information becomes available and/or certain spending trends become known, management will evaluate such information in determination of the current estimate of the environmental liability. As part of the Company's 2020 Restructuring Program, in the third quarter of 2020, the Company recorded a pretax charge related to environmental remediation matters. This charge resulted from the Company's evaluation of the costs required to manage remediation activities at sites Dow will permanently shut down as part of its 2020 Restructuring Program. In addition, the Company recorded indemnification assets of $50 million related to Dow Silicones' environmental matters. The Company recognized a pretax charge, net of indemnifications, of $56 million, included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Performance Materials & Coatings ($52 million) and Corporate ($4 million). See Note 6 for additional information. In the third quarter of 2019, the Company recorded a pretax charge related to environmental remediation matters at a number of current and historical locations. The charge primarily resulted from: the culmination of long-standing negotiations and discussions with regulators and agencies, including technical studies supporting higher cost estimates for final or staged remediation plans; the Company’s evaluation of the cost required to manage remediation activities at sites affected by Dow’s separation from DowDuPont and related agreements with Corteva and DuPont; and, the Company’s review of its closure strategies and obligations to monitor ongoing operations and maintenance activities. In addition, the Company recorded indemnification assets of $48 million related to Dow Silicones’ environmental matters. The Company recognized a pretax charge, net of indemnifications, of $399 million related to these environmental matters, included in “Cost of sales” in the consolidated statements of income and related to Packaging & Specialty Plastics ($5 million), Industrial Intermediates & Infrastructure ($8 million), Performance Materials & Coatings ($50 million) and Corporate ($336 million). The following table summarizes the activity in the Company's accrued obligations for environmental matters for the years ended December 31, 2021 and 2020: Accrued Obligations for Environmental Matters 2021 2020 In millions Balance at Jan 1 $ 1,244 $ 1,155 Accrual adjustment 159 285 Payments against reserve (162) (198) Foreign currency impact (21) 2 Balance at Dec 31 $ 1,220 $ 1,244 The amounts charged to income on a pretax basis related to environmental remediation totaled $158 million in 2021, $234 million in 2020 and $588 million in 2019. Capital expenditures for environmental protection were $65 million in 2021, $80 million in 2020 and $83 million in 2019. Midland Off-Site Environmental Matters On June 12, 2003, the Michigan Department of Environmental Quality ("MDEQ") issued a Hazardous Waste Operating License (the "License") to the Company’s Midland, Michigan, manufacturing site (the “Midland Site”), which was renewed and replaced by the MDEQ on September 25, 2015, and included provisions requiring the Company to conduct an investigation to determine the nature and extent of off-site contamination in the City of Midland soils, the Tittabawassee River and Saginaw River sediment and floodplain soils, and the Saginaw Bay, and, if necessary, undertake remedial action. In 2016, final regulatory approval was received from the MDEQ for the City of Midland and the Company is continuing the long term monitoring requirements of the Remedial Action Plan. Tittabawassee and Saginaw Rivers, Saginaw Bay The Company, the U.S. Environmental Protection Agency (“EPA”) and the State of Michigan ("State") entered into an administrative order on consent (“AOC”), effective January 21, 2010, that requires the Company to conduct a remedial investigation, a feasibility study and a remedial design for the Tittabawassee River, the Saginaw River and the Saginaw Bay, and pay the oversight costs of the EPA and the State under the authority of the Comprehensive Environmental Response, Compensation, and Liability Act. These actions, to be conducted under the lead oversight of the EPA, will build upon the investigative work completed under the State Resource Conservation Recovery Act program from 2005 through 2009. The Tittabawassee River, beginning at the Midland Site and extending down to the first six miles of the Saginaw River, are designated as the first Operable Unit for purposes of conducting the remedial investigation, feasibility study and remedial design work. This work will be performed in a largely upriver to downriver sequence for eight geographic segments of the Tittabawassee and upper Saginaw Rivers. In the first quarter of 2012, the EPA requested the Company address the Tittabawassee River floodplain ("Floodplain") as an additional segment. In January 2015, the Company and the EPA entered into an order to address remediation of the Floodplain. The remedial work is expected to continue over the next two years as river levels allow. The remainder of the Saginaw River and the Saginaw Bay are designated as a second Operable Unit and the work associated with that unit may also be geographically segmented. The AOC does not obligate the Company to perform removal or remedial action; that action can only be required by a separate order. The Company and the EPA have been negotiating orders separate from the AOC that obligate the Company to perform remedial actions under the scope of work of the AOC. The Company and the EPA have entered into six separate orders to perform limited remedial actions in seven of the eight geographic segments in the first Operable Unit, including the Floodplain. Dow has received from the EPA a Notice of Completion of Work for three of these six orders and the Company continues the long-term monitoring requirements. Dow also has entered into a separate order to perform a limited remedial action for certain properties located within the second Operable Unit. Alternative Dispute Resolution Process The Company, the EPA, the U.S. Department of Justice and the natural resource damage trustees (which include the Michigan Office of the Attorney General, the Michigan Department of Environment, Great Lakes and Energy, the Michigan Department of Natural Resources, the U.S. Fish and Wildlife Service, the U.S. Bureau of Indian Affairs and the Saginaw-Chippewa Indian Tribe of Michigan) have been engaged in negotiations to seek to resolve potential governmental claims against the Company for natural resource damages related to historical off-site contamination associated with the City of Midland, the Tittabawassee and Saginaw Rivers and the Saginaw Bay. The Company and the governmental parties started meeting in the fall of 2005 and entered into a Confidentiality Agreement in December 2005. On July 20, 2020, the U.S. District Court for the Eastern District of Michigan ("District Court") entered a final consent decree in Civil Action No. 1:19-cv-13292 between the Company and federal, state and tribal trustees to resolve allegations of natural resource damages arising from the historic operations of the Company’s Midland Site. The consent decree required the Company to pay a $15 million cash settlement to be used for long-term maintenance and trustee-selected remediation projects with an additional $7 million to specified local projects managed by third parties. These funds were paid in December 2020. The consent decree further requires the Company to complete 13 additional environmental restoration projects which are valued by the trustees at approximately $77 million, to be conducted over the next several years. In 2021, the Company, working with the trustees, advanced the design plans for several of the Company required environmental restoration projects with implementation in progress for one of the projects. At December 31, 2021, the accrual for these off-site matters was $104 million (included in the total accrued obligation of $1,220 million). At December 31, 2020, the Company had an accrual for these off-site matters of $107 million (included in the total accrued obligation of $1,244 million). Environmental Matters Summary It is the opinion of the Company’s management that the possibility is remote that costs in excess of those disclosed will have a material impact on the Company’s results of operations, financial condition or cash flows. Litigation Asbestos-Related Matters of Union Carbide Corporation Introduction Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past four decades. These suits principally allege personal injury resulting from exposure to asbestos-containing products and frequently seek both actual and punitive damages. The alleged claims primarily relate to products that Union Carbide sold in the past, alleged exposure to asbestos-containing products located on Union Carbide’s premises and Union Carbide’s responsibility for asbestos suits filed against a former Union Carbide subsidiary, Amchem Products, Inc. ("Amchem"). In many cases, plaintiffs are unable to demonstrate that they have suffered any compensable loss as a result of such exposure, or that injuries incurred in fact resulted from exposure to Union Carbide’s products. Union Carbide expects more asbestos-related suits to be filed against Union Carbide and Amchem in the future, and will aggressively defend or reasonably resolve, as appropriate, both pending and future claims. Estimating the Asbestos-Related Liability Based on a study completed by Ankura Consulting Group, LLC ("Ankura") in January 2003, Union Carbide increased its December 31, 2002, asbestos-related liability for pending and future claims for a 15-year period ending in 2017 to $2.2 billion, excluding future defense and processing costs. In subsequent years, Union Carbide compared current asbestos claim and resolution activity to the results of the most recent Ankura study at each balance sheet date to determine whether the accrual continued to be appropriate. In 2016, Ankura completed a study to provide estimates for the undiscounted cost of disposing of pending and future claims against Union Carbide and Amchem through the terminal year of 2049, including a reasonable forecast of future defense and processing costs. Based on the study and Union Carbide’s internal review of asbestos claim and resolution activity, Union Carbide determined estimating the liability through the terminal year of 2049 was more appropriate due to increased knowledge and data about the costs to resolve claims and diminished volatility in filing rates. Union Carbide and the Company also determined that estimating and accruing a liability for future asbestos-related defense and processing costs was more appropriate as such costs represent expenditures related to legacy activities that do not contribute to current or future revenue generating activities of Union Carbide and the Company and is also reflective of the manner in which Union Carbide manages its asbestos-related exposure, including careful monitoring of the correlation between defense spending and resolution costs. As a result, in the fourth quarter of 2016, Union Carbide recorded a $1,113 million increase in its asbestos-related liability for pending and future claims, including future defense and processing costs. Each October, Union Carbide requests Ankura to review its historical asbestos claim and resolution activity through the third quarter of the current year, including asbestos-related defense and processing costs, to determine the appropriateness of updating the most recent study. In December 2019, Ankura stated that an update of its December 2018 study would not provide a more likely estimate of future events than the estimate reflected in the study and, therefore, the estimate in the study remained applicable. Based on Union Carbide's internal review process and Ankura's response, Union Carbide determined that no change to the accrual was required. In December 2020, Ankura completed a study of Union Carbide's historical asbestos claim and resolution activity through September 30, 2020, including asbestos-related defense and processing costs, and provided estimates for the undiscounted cost of disposing of pending and future claims against Union Carbide and Amchem through the terminal year of 2049. Based on the study and Union Carbide's internal review process, it was determined that no adjustment to the accrual was required. At December 31, 2020, the asbestos-related liability for pending and future claims against Union Carbide and Amchem, including future asbestos-related defense and processing costs, was $1,098 million, and approximately 22 percent of the recorded liability related to pending claims and approximately 78 percent related to future claims. In December 2021, Ankura stated that an update of its December 2020 study would not provide a more likely estimate of future events than the estimate reflected in the study and, therefore, the estimate in the study remained applicable. Based on Union Carbide's internal review process and Ankura's response, Union Carbide determined that no change to the accrual was required. At December 31, 2021, the asbestos-related liability for pending and future claims against Union Carbide and Amchem, including future asbestos-related defense and processing costs, was $1,016 million, and approximately 25 percent of the recorded liability related to pending claims and approximately 75 percent related to future claims. Summary The Company's management believes the amounts recorded by Union Carbide for the asbestos-related liability, including defense and processing costs, reflect reasonable and probable estimates of the liability based upon current, known facts. However, future events, such as the number of new claims to be filed and/or received each year, the average cost of defending and disposing of each such claim, as well as the numerous uncertainties surrounding asbestos litigation in the United States over a significant period of time, could cause the actual costs for Union Carbide to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability. Because of the uncertainties described above, Union Carbide cannot estimate the full range of the cost of resolving pending and future asbestos-related claims facing Union Carbide and Amchem. As a result, it is reasonably possible that an additional cost of disposing of Union Carbide's asbestos-related claims, including future defense and processing costs, could have a material impact on the Company's results of operations and cash flows for a particular period and on the consolidated financial position. Dow Silicones Chapter 11 Related Matters Introduction In 1995, Dow Silicones, then a 50:50 joint venture between the Company and Corning Incorporated ("Corning"), voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in order to resolve Dow Silicones’ breast implant liabilities and related matters (the “Chapter 11 Proceeding”). Dow Silicones emerged from the Chapter 11 Proceeding on June 1, 2004 (the “Effective Date”) and is implementing the Joint Plan of Reorganization (the “Plan”). The Plan provides funding for the resolution of breast implant and other product liability litigation covered by the Chapter 11 Proceeding. As of June 1, 2016, Dow Silicones is a wholly owned subsidiary of the Company. Breast Implant and Other Product Liability Claims Under the Plan, a product liability settlement program administered by an independent claims office (the “Settlement Facility”) was created to resolve breast implant and other product liability claims. Product liability claimants rejecting the settlement program in favor of pursuing litigation must bring suit against a litigation facility (the “Litigation Facility”). Under the Plan, total payments committed by Dow Silicones to resolving product liability claims are capped at a maximum $2,350 million net present value (“NPV”) determined as of the Effective Date using a discount rate of 7 percent (approximately $4,081 million undiscounted at December 31, 2021). Of this amount, no more than $400 million NPV determined as of the Effective Date can be used to fund the Litigation Facility. Dow Silicones had an obligation to fund the Settlement Facility and the Litigation Facility over a 16-year period, commencing at the Effective Date. At December 31, 2021, Dow Silicones and its insurers have made life-to-date payments of $1,792 million to the Settlement Facility and Dow Silicones is currently making payments to fund the Settlement Facility. In accordance with ASC Topic 450 "Accounting for Contingencies," the Company records a liability for breast implant and other product liability claims (“Implant Liability”), which reflects the estimated impact of the settlement of pending claims. The claim filing deadline passed in June 2019. All claims have been received and are being processed. Based on the claims filed at and before the deadline, Dow Silicones estimates that it will be obligated to contribute an additional $130 million to the Settlement Facility at December 31, 2021 ($160 million at December 31, 2020) which was included in “Accrued and other current liabilities” and "Other noncurrent obligations" in the consolidated balance sheets. In the third quarter of 2019, with the assistance of a third party consultant ("Consultant"), Dow Silicones updated its Implant Liability estimate, primarily reflecting a decrease in Class 16 claims, a decrease resulting from the passage of time, decreased claim filing activity and administrative costs compared with the previous estimate, and an increase in investment income resulting from insurance proceeds. Based on the Consultant's updated estimate and Dow Silicones own review of claim filing activity, Dow Silicones determined that an adjustment to the Implant Liability was required. Accordingly, in the third quarter of 2019, Dow Silicones decreased its Implant Liability $98 million and decreased its corresponding Class 16 receivable $13 million, both included in “Sundry income (expense) - net” in the consolidated statements of income and related to Corporate. The estimate was updated again in the second quarter of 2020 with the assistance of the Consultant, which primarily reflected decreased administrative costs compared with the previous estimate and an increase in investment income resulting from insurance proceeds. Dow Silicones is not aware of circumstances that would change the factors used in estimating the Implant Liability and believes the recorded liability reflects the best estimate of the remaining funding obligations under the Plan; however, the estimate relies upon a number of significant assumptions, including: future acceptance rates, disease mix, and payment values will be materially consistent with historical experience; no material negative outcomes in future controversies or disputes over Plan interpretation will occur; and the Plan will not be modified. If actual outcomes related to any of these assumptions prove to be materially different, the future liability to fund the Plan may be materially different than the amount estimated. Commercial Creditor Issues The Plan provides that each of Dow Silicones commercial creditors (the “Commercial Creditors”) would receive in cash the sum of (a) an amount equal to the principal amount of their claims and (b) interest on such claims. Upon the Plan becoming effective, Dow Silicones paid approximately $1,500 million to the Commercial Creditors, representing principal and an amount of interest that Dow Silicones considers undisputed. On August 19, 2019, Dow Silicones entered into a settlement agreement with the Commercial Creditors related to the remaining disputed portion, obligating Dow Silicones to pay $172 million, inclusive of the Commercial Creditors' legal costs. The settlement was approved by the District Court. As a result of the settlement agreement, in the third quarter of 2019, the Company recorded a pretax charge of $50 million, net of indemnifications of $37 million, included in "Sundry Income (expense) - net" in the consolidated statements of income and related to Corporate. The settlement was paid to the Commercial Creditors in the fourth quarter of 2019. The litigation is now concluded. Summary The amounts recorded by Dow Silicones for the Chapter 11 related matters described above were based upon current, known facts, which management believes reflect reasonable and probable estimates of the liability. However, future events could cause the actual costs for Dow Silicones to be higher or lower than those projected or those recorded. Any such events could result in an increase or decrease in the recorded liability. Other Litigation Matters In addition to the specific matters described above, the Company is party to a number of other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation, and other actions. Certain of these actions purport to be class actions and seek damages in very large amounts. All such claims are being contested. The Company has an active risk management program consisting of numerous insurance policies secured from many carriers at various times. These policies may provide coverage that could be utilized to minimize the financial impact, if any, of certain contingencies described above. It is the opinion of the Company’s management that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the results of operations, financial condition and cash flows of the Company. Indemnifications with Corning In connection with the June 1, 2016 ownership restructure of Dow Silicones, the Company is indemnified by Corning for at least 50 percent of future losses associated with certain pre-closing liabilities, including the Implant Liability, Commercial Creditors issues and certain environmental matters described in the preceding sections, subject to certain conditions and limits. The maximum amount of indemnified losses which may be recovered are subject to a cap that declines over time. Indemnified losses are capped at $1 billion between May 31, 2018 and May 31, 2023, and no recoveries are permitted after May 31, 2023. The Company had indemnification assets of $95 million at December 31, 2021 ($115 million at December 31, 2020), which was included in "Other current assets" and "Noncurrent receivables" in the consolidated balance sheets. Gain Contingency - Dow v. Nova Chemicals Corporation Patent Infringement Matter In December 2010, Dow filed suit in the Federal Court in Ontario, Canada ("Federal Court") alleging that Nova Chemicals Corporation ("Nova") was infringing the Company's Canadian polyethylene patent 2,106,705 (the "'705 Patent"). Nova counterclaimed on the grounds of invalidity and non-infringement. In accordance with Canadian practice, the suit was bifurcated into a merits phase, followed by a damages phase. Following trial in the merits phase, in May 2014 the Federal Court ruled that the Company's '705 Patent was valid and infringed by Nova. Nova appealed to the Canadian Federal Court of Appeal, which affirmed the Federal Court decision in August 2016. Nova then sought leave to appeal its loss to the Supreme Court of Canada ("Court"), which dismissed Nova’s petition in April 2017. As a result, Nova has exhausted all appeal rights on the merits, and it is undisputed that Nova owes the Company the profits it earned from its infringing sales as determined in the trial for the damages phase. In April 2017, the Federal Court issued a Public Judgment in the damages phase, which detailed its conclusions on how to calculate the profits to be awarded to the Company. In June 2017, the Federal Court ordered Nova to pay $645 million Canadian dollars (equivalent to $495 million U.S. dollars) to the Company, plus pre- and post-judgment interest, for which the Company received payment of $501 million from Nova in July 2017. Although Nova is appealing portions of the damages judgment, certain portions of it are indisputable and can be retained by the Company regardless of the outcome of any further appeals by Nova. As a result of these actions and in accordance with ASC Topic 450-30 "Gain Contingencies," the Company recorded a $160 million pretax gain in the second quarter of 2017. On September 15, 2020, the Canadian Federal Court of Appeal dismissed Nova's appeal of the damages judgment, thus affirming the trial court's decision in its entirety. In November 2020, Nova filed an application for leave to appeal this decision to the Court. In May 2021, the Court granted Nova's application for leave and agreed to review the damages judgment. The Court will hear oral argument on the matter in the first half of 2022 and the Company expects a decision by the end of 2022. The Company is confident of its chances to continue to defend the entire judgment, particularly the trial and appellate courts' determinations on important factual issues, which will be accorded deferential review on appeal. At December 31, 2021, the Company had $341 million ($341 million at December 31, 2020) included in "Accrued and other current liabilities" related to the disputed portion of the damages judgment. Gain Contingency - Dow v. Nova Chemicals Corporation Ethylene Asset Matter On September 18, 2019, the Court of the Queen’s Bench in Alberta, Canada, signed a judgment ordering Nova to pay the Company $1.43 billion Canadian dollars (equivalent to approximately $1.08 billion U.S. dollars) by October 11, 2019, for damages the Company incurred through 2012 related to the companies’ jointly-owned ethylene asset in Joffre, Alberta, Canada. The Court of the Queen's Bench in Alberta, Canada, which initially ruled in June 2018, found that Nova failed to operate the ethylene asset at full capacity for more than ten years, and furthermore, that Nova violated several contractual agreements related to the Company receiving its share of the asset’s ethylene production. These actions resulted in reduced productivity and sales for the Company. Nova has appealed the judgment, however, certain portions of it are not in dispute and are owed to the Company regardless of the outcome of Nova's appeal. As a result of these actions and in accordance with ASC Topic 450-30 “Gain Contingencies,” the Company recorded a $186 million pretax gain in the third quarter of 2019, of which $170 million was included in "Sundry income (expense) - net" and $16 million was included in "Selling, general and administrative expenses" in the consolidated statements of income and related to Packaging & Specialty Plastics. In October 2019, Nova paid $1.08 billion Canadian dollars (equivalent to approximately $0.8 billion U.S. dollars) directly to the Company, and remitted $347 million Canadian dollars to the Canada Revenue Agency ("CRA") for the tax account of one of the Company's subsidiaries. The Company sought a refund of the entire amount remitted to CRA. On March 31, 2020, the Company received the full refund from CRA, equivalent to $259 million U.S. dollars. In preparation for the June 2020 appellate hearing on the case, Nova provided the Court of the Queen's Bench in Alberta, Canada, an updated schedule of the financial impact of the issues on appeal, which explained that even if Nova prevails on all appeal issues, the Company would still be entitled to retain an amount in excess of the gain recognized in 2019. As a result, the Company recorded an $18 million pretax gain in the second quarter of 2020, of which $12 million was included in "Selling, general and administrative expenses" and $6 million was include d in "Sundry income (expense) - net" in the consolidated statements of income and related to Packaging & Specialty Plastics. On September 16, 2020, the Court of Appeal of Alberta issued its decision, affirming the trial court's liability finding, upholding the majority of Dow's damages and requiring the trial court to recalculate a portion of damages. In the fourth quarter of 2020, Nova chose not to petition the Court to review the appellate court decision, making additional portions of the ruling in Dow’s favor final and no longer subject to dispute. As a result, the Company recorded a $552 million pretax gain in the fourth quarter of 2020, of which $538 million was included in "Sundry income (expense) - net" and $14 million was included in "Selling, general and administrative expenses" in the consolidated statements of income and related to Packaging & Specialty Plastics. At December 31, 2021, $323 million ($323 million at December 31, 2020) was included in "Other noncurrent obligations" in the Company's consolidated balance sheets related to the disputed portion of the damages judgment. Dow continues to seek an award of additional damages for the period from 2013 through 2018. The damages hearing began in the trial court in November 2021 that would resolve the impact of the appellate ruling and quantify Dow's damages for the 2013-2018 period. Luxi Chemical Group Breach of Contract Matter In November 2017, an arbitration panel of the Stockholm Chamber of Commerce held that Luxi Chemical Group Co., Ltd. (“Luxi”), based in Shandong Province, China, violated a secrecy and non-use agreement related to the Dow and Johnson Matthey Davy Technologies Limited (“JM”) LP Oxo SM Process by using Dow and JM protected information in the design, construction, and operation of its butanol and 2-ethylhexanol plants, awarding damages, fees and costs, plus interest, to both Dow and JM. In September 2021, Luxi paid the arbitration award and interest assessment and, as a result, Dow recorded a pretax gain of $54 million included in “Sundry income (expense) – net” in the consolidated statements of income and related to Industrial Intermediates & Infrastructure. Brazilian Tax Credits In March 2017, the Federal Supreme Court of Brazil (“Brazil Supreme Court”) ruled in a leading case that a Brazilian value-added tax ("ICMS") should not be included in the base used to calculate a taxpayer's federal contribution on total revenue known as PIS/COFINS (the “2017 Decision”). Previously, three of the Company’s Brazilian subsidiaries filed lawsuits challenging the inclusion of ICMS in their calculation of PIS/COFINS, seeking recovery of excess taxes paid. In response to the 2017 Decision, the Brazilian tax authority filed an appeal seeking clarification of the amount of ICMS tax to exclude from the calculation of PIS/COFINS. In May 2021, the Brazil Supreme Court ruled in a leading case related to the amount of ICMS tax to exclude from the calculation of PIS/COFINS, which r

Leases [Abstract]
Lessee, Operating And Finance Leases	LEASES Operating lease ROU assets are included in "Operating lease right-of-use assets" while finance lease ROU assets are included in "Net property" in the consolidated balance sheets. With respect to lease liabilities, operating lease liabilities are included in "Operating lease liabilities - current" and "Operating lease liabilities - noncurrent," and finance lease liabilities are included in "Long-term debt due within one year" and "Long-Term Debt" in the consolidated balance sheets. Dow routinely leases sales and administrative offices, power plants, production facilities, warehouses and tanks for product storage, aircraft, motor vehicles, railcars, computers, office machines and equipment. Some leases contain renewal provisions, purchase options and escalation clauses and the terms for these leased assets vary depending on the lease agreement. These leased assets have remaining lease terms of up to 54 years. See Note 1 for additional information on leases. The components of lease cost for operating and finance leases for the years ended December 31, 2021, 2020 and 2019 were as follows: Lease Cost 2021 2020 2019 In millions Operating lease cost $ 494 $ 484 $ 532 Finance lease cost Amortization of right-of-use assets - finance 76 58 39 Interest on lease liabilities - finance 27 25 25 Total finance lease cost 103 83 64 Short-term lease cost 238 213 204 Variable lease cost 381 199 198 Sublease income (6) (5) (4) Total lease cost $ 1,210 $ 974 $ 994 The following table provides supplemental cash flow and other information related to leases: Other Lease Information 2021 2020 2019 In millions Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 497 $ 482 $ 544 Operating cash flows for finance leases $ 27 $ 25 $ 25 Financing cash flows for finance leases $ 74 $ 58 $ 34 Right-of-use assets obtained in exchange for lease obligations: Operating leases 1, 2 $ (25) $ 185 $ 2,476 Finance leases 1 $ 512 $ 178 $ 89 1.

The Company recognized a pretax loss related to the lease buy-outs of $37 million included in “Sundry income (expense) - net” in the consolidated statements of income. The lease buy-outs are included in “Purchases of previously leased assets” in the consolidated statements of cash flows. Additionally, in 2021, the Company amended an agreement to extend leases of certain assets. The amendment and related remeasurement resulted in a reclassification of $73 million from “Operating lease liabilities – noncurrent” to “Long-Term Debt” and $34 million from “Operating lease liabilities - current” to “Long-term debt due within one year." In addition to the reclassifications, the amendment increased “Long-Term Debt” by $152 million and decreased “Long-term debt due within one year" by $2 million.

Stockholders' Equity Note [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Common Stock Dow Inc. Dow Inc. was incorporated in 2018 with 100 authorized and issued shares of common stock, par value $0.01 per share, owned solely by its parent company, DowDuPont. In the first quarter of 2019, in connection with the separation and distribution of DowDuPont’s materials science business, the number of authorized shares of common stock was increased to 5,000,000,000 shares, par value $0.01 per share, and Dow Inc.'s 100 shares of issued common stock were recapitalized into 748,771,240 shares of common stock. Dow Inc.'s common stock was solely owned by DowDuPont through March 31, 2019, and on April 1, 2019, Dow Inc. became an independent, publicly traded company. Dow Inc. common stock is listed on the NYSE under the symbol “DOW.” See Note 3 for additional information. The Company may issue shares of Dow Inc. common stock out of treasury stock or as new shares of common stock for options exercised and for the release of restricted stock units ("RSUs"), performance stock units ("PSUs") and the Employee Stock Purchase Plan ("ESPP") program. Common stock shares issued to employees and non-employee directors was approximately 8.2 million in 2021 (4.8 million in 2020). Subsequent to the separation from DowDuPont, the number of new Dow Inc. common stock shares issued to employees and non-employee directors was approximately 2.5 million in 2019. See Note 21 for additional information on the Company's equity awards. TDCC Effective with the Merger and through March 31, 2019, TDCC had 100 authorized and issued shares of common stock, par value $0.01 per share, owned solely by DowDuPont. Effective with the separation from DowDuPont, TDCC became a wholly owned subsidiary of Dow Inc., which now holds all 100 authorized and issued shares of common stock of TDCC. See Note 3 for additional information. Retained Earnings Dow Inc. There are no significant restrictions limiting Dow Inc.’s ability to pay dividends. Dow Inc. declared dividends of $2.80 per share in 2021 ($2.80 per share in 2020 and $2.10 per share in 2019, subsequent to the separation from DowDuPont). Undistributed earnings of nonconsolidated affiliates included in retained earnings were $1,155 million at December 31, 2021 and $716 million at December 31, 2020. TDCC Effective with the Merger, TDCC no longer had publicly traded common stock. TDCC's common shares were owned solely by DowDuPont, prior to the separation on April 1, 2019, and TDCC's Board determined whether or not there would be a dividend distribution to DowDuPont. Effective with the separation from DowDuPont on April 1, 2019, TDCC became a wholly owned subsidiary of Dow Inc. and TDCC's Board determines whether or not there will be a dividend distribution to Dow Inc. TDCC declared and paid dividends to Dow Inc. of $3,264 million in 2021, $2,233 million in 2020 and $201 million in 2019. In 2019, TDCC declared and paid dividends to DowDuPont of $535 million. Employee Stock Ownership Plan The Dow Employee Stock Ownership Plan (the “ESOP”) is an integral part of The Dow Chemical Company Employees’ Savings Plan (the “Savings Plan”). A significant majority of full-time employees in the United States are eligible to participate in the Savings Plan. The Company uses the ESOP to provide its matching contribution in the form of stock to Plan participants. Effective with the Merger, shares of TDCC Common Stock held by the ESOP were converted into shares of DowDuPont Common Stock at a ratio of 1:1. Effective with the separation from DowDuPont, the DowDuPont Common Stock held by the ESOP received a Dow Inc. Common Stock share dividend at a ratio of 3:1, resulting in the ESOP holding both DowDuPont and Dow Inc. shares. Subsequent to the separation from DowDuPont, the ESOP independent fiduciary sold the DowDuPont shares and purchased additional Dow Inc. shares with the proceeds. In connection with the acquisition of Rohm and Haas on April 1, 2009, the Rohm and Haas Employee Stock Ownership Plan (the "Rohm and Haas ESOP") was merged into the Savings Plan, and the Company assumed the $78 million balance of debt at 9.8 percent interest with final maturity in 2020 that was used to finance share purchases by the Rohm and Haas ESOP in 1990. The debt was fully repaid in 2020 which resulted in an outstanding balance of zero at December 31, 2020. Dividends on unallocated shares held by the ESOP are used by the ESOP to make debt service payments and to purchase additional shares if dividends exceed the debt service payments. Dividends on allocated shares are used by the ESOP to make debt service payments to the extent needed; otherwise, they are paid to the Savings Plan participants. Shares are released for allocation to participants based on the ratio of the current year’s debt service to the sum of the principal and interest payments over the life of the loan. The shares are allocated to Plan participants in accordance with the terms of the Savings Plan. The unallocated shares are excluded from the Company's earnings per share calculation. Compensation expense for allocated shares is recorded at the fair value of the shares on the date of allocation. Compensation expense reflected in income from continuing operations for ESOP shares was $77 million in 2021, $72 million in 2020 and $77 million in 2019. At December 31, 2021, 4.0 million shares out of a total 4.5 million shares held by the ESOP had been allocated to participants’ accounts and 0.5 million shares, at a fair value of $29 million, were considered unearned. Treasury Stock Dow Inc. On April 1, 2019, Dow Inc.'s Board ratified the share repurchase program originally approved on March 15, 2019, authorizing up to $3.0 billion to be spent on the repurchase of the Company's common stock, with no expiration date. In 2021, Dow Inc. repurchased $1.0 billion of Dow Inc. common stock ($125 million in 2020 and $500 million in 2019). At December 31, 2021, $1.4 billion of the share repurchase program authorization remained available for repurchases. The Company may issue shares of Dow Inc. common stock out of treasury stock or as new shares of common stock for options exercised and for the release of RSUs, PSUs and ESPP. The Company did not issue any treasury shares to employees and non-employee directors under its stock-based compensation programs for the years ended December 31, 2021, 2020 and 2019. See Note 21 for additional information on changes to the Company's equity awards in connection with the separation from DowDuPont. The following table provides a reconciliation of Dow Inc. common stock activity for the years ended December 31, 2021, 2020 and 2019: Shares of Dow Inc.

PENSION PLANS AND OTHER POSTRET

PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS (Notes)	12 Months Ended

Retirement Benefits [Abstract]
PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS	PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS Defined Benefit Pension Plans The Company has both funded and unfunded defined benefit pension plans that cover employees in the United States and a number of other countries. The U.S. tax-qualified plan covering the parent company is the largest plan. Benefits for employees hired before January 1, 2008, are based on length of service and the employee’s three highest consecutive years of compensation. Employees hired after January 1, 2008, earn benefits that are based on a set percentage of annual pay, plus interest. On March 4, 2021, the Company announced changes to its U.S. tax-qualified and non-qualified pension plans. Effective December 31, 2023 ("Effective Date"), the Company will freeze the pensionable compensation and credited service amounts used to calculate pension benefits for employees who participate in its U.S. tax-qualified and non-qualified retirement programs (collectively, the "U.S. Plans"). As a result, at the Effective Date and subject to any bargaining obligations required by law, active participants of the U.S. Plans will not accrue additional benefits for future service and compensation. In connection with these plan amendments, the Company remeasured its U.S. Plans effective February 28, 2021, which resulted in a pretax actuarial gain of $1,268 million, included in other comprehensive income and inclusive of a $345 million reduction in the projected benefit obligation resulting from the plan amendments, and a pretax curtailment gain of $19 million, recognized in the first quarter of 2021. The Company's funding policy is to contribute to the plans when pension laws and/or economics either require or encourage funding. On March 4, 2021, the Company elected to contribute $1 billion to its U.S. tax-qualified pension plans. Total global pension contributions were $1,219 million in 2021, which includes contributions necessary to fund benefit payments for the Company's unfunded pension plans. The Company expects to contribute approximately $180 million to its pension plans in 2022. The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for all plans are summarized in the table below: Weighted-Average Assumptions for All Pension Plans Benefit Obligations Net Periodic Benefit Costs 2021 2020 2021 2020 2019 Discount rate 2.57 % 2.20 % 2.40 % 2.81 % 3.50 % Interest crediting rate for applicable benefits 3.57 % 3.55 % 3.55 % 3.51 % 3.72 % Rate of compensation increase 3.94 % 3.91 % 3.91 % 3.92 % 3.92 % Expected return on plan assets 6.86 % 7.00 % 7.11 % The weighted-average assumptions used to determine pension plan obligations and net periodic benefit costs for U.S. plans are summarized in the table below: Weighted-Average Assumptions for U.S. Pension Plans Benefit Obligations Net Periodic Benefit Costs 2021 2020 2021 2020 2019 Discount rate 3.04 % 2.71 % 3.03 % 3.41 % 4.15 % Interest crediting rate for applicable benefits 4.50 % 4.50 % 4.50 % 4.50 % 4.50 % Rate of compensation increase 4.25 % 4.25 % 4.25 % 4.25 % 4.25 % Expected return on plan assets 7.96 % 7.95 % 7.92 % Other Postretirement Benefit Plans The Company provides certain health care and life insurance benefits to retired employees and survivors. The Company’s plans outside of the United States are not significant; therefore, this discussion relates to the U.S. plans only. The plans provide health care benefits, including hospital, physicians’ services, drug and major medical expense coverage, and life insurance benefits. In general, for employees hired before January 1, 1993, the plans provide benefits supplemental to Medicare when retirees are eligible for these benefits. The Company and the retiree share the cost of these benefits, with the Company portion increasing as the retiree has increased years of credited service, although there is a cap on the Company portion. The Company has the ability to change these benefits at any time. Employees hired after January 1, 2008, are not covered under the plans. The Company funds most of the cost of these health care and life insurance benefits as incurred. In 2021, the Company did not make any contributions to its other postretirement benefit plan trusts. The trusts did not hold assets at December 31, 2021. The Company does not expect to contribute assets to its other postretirement benefit plan trusts in 2022. The weighted-average assumptions used to determine other postretirement benefit plan obligations and net periodic benefit costs for the U.S. plans are provided below: Weighted-Average Assumptions for U.S. Other Postretirement Benefits Plans Benefit Obligations Net Periodic Benefit Costs 2021 2020 2021 2020 2019 Discount rate 2.85 % 2.38 % 2.38 % 3.19 % 4.01 % Health care cost trend rate assumed for next year 6.50 % 6.75 % 6.75 % 6.25 % 6.50 % Rate to which the cost trend rate is assumed to decline (the ultimate health care cost trend rate) 5.00 % 5.00 % 5.00 % 5.00 % 5.00 % Year that the rate reaches the ultimate health care cost trend rate 2028 2028 2028 2025 2025 Assumptions The Company determines the expected long-term rate of return on plan assets by performing a detailed analysis of key economic and market factors driving historical returns for each asset class and formulating a projected return based on factors in the current environment. Factors considered include, but are not limited to, inflation, real economic growth, interest rate yield, interest rate spreads and other valuation measures and market metrics. The expected long-term rate of return for each asset class is then weighted based on the strategic asset allocation approved by the governing body for each plan. The Company’s historical experience with the pension fund asset performance is also considered. The Company uses the spot rate approach to determine the discount rate utilized to measure the service cost and interest cost components of net periodic pension and other postretirement benefit costs for the U.S. and other selected countries. Under the spot rate approach, the Company calculates service cost and interest cost by applying individual spot rates from the Willis Towers Watson RATE:Link yield curve (based on high-quality corporate bond yields) for each selected country to the separate expected cash flow components of service cost and interest cost. Service cost and interest cost for all other plans are determined on the basis of the single equivalent discount rates derived in determining those plan obligations. The discount rates utilized to measure the pension and other postretirement obligations of the U.S. plans are based on the yield on high-quality corporate fixed income investments at the measurement date. Future expected actuarially determined cash flows for the Company’s U.S. plans are individually discounted at the spot rates under the Willis Towers Watson U.S. RATE:Link 60-90 corporate yield curve (based on 60th to 90th percentile high-quality corporate bond yields) to arrive at the plan’s obligations as of the measurement date. The Company’s mortality assumption used for the US plans is a benefit-weighted version of the Society of Actuaries’ RP-2014 base table with future rates of mortality improvement based on a modified version of the assumptions used in the Social Security Administration’s 2021 trustees report. Summarized information on the Company's pension and other postretirement benefit plans is as follows: Change in Projected Benefit Obligations, Plan Assets and Funded Status of All Significant Plans Defined Benefit Pension Plans Other Postretirement Benefit Plans In millions 2021 2020 2021 2020 Change in projected benefit obligations: Benefit obligations at beginning of year $ 35,309 $ 32,621 $ 1,464 $ 1,535 Service cost 387 399 7 7 Interest cost 594 767 23 40 Plan participants' contributions 10 12 — — Actuarial changes in assumptions and experience (820) 3,021 (98) 7 Benefits paid (1,582) (1,569) (141) (132) Plan amendments 2 8 — — Acquisitions/divestitures/other 1 8 (692) — — Effect of foreign exchange rates (545) 791 (4) 7 Termination benefits/curtailments/settlements 2 (386) (49) — — Benefit obligations at end of year $ 32,977 $ 35,309 $ 1,251 $ 1,464 Change in plan assets: Fair value of plan assets at beginning of year $ 26,406 $ 24,908 $ — $ — Actual return on plan assets 2,501 2,877 — — Employer contributions 1,219 299 — — Plan participants' contributions 10 12 — — Benefits paid (1,582) (1,569) — — Other 3 10 (681) — — Effect of foreign exchange rates (397) 571 — — Settlements — (11) — — Fair value of plan assets at end of year $ 28,167 $ 26,406 $ — $ — Funded status: U.S. plans with plan assets $ (2,585) $ (5,873) $ — $ — Non-U.S. plans with plan assets (1,467) (2,222) — — All other plans (758) (808) (1,251) (1,464) Funded status at end of year $ (4,810) $ (8,903) $ (1,251) $ (1,464) Amounts recognized in the consolidated balance sheets at Dec 31: Deferred charges and other assets $ 1,173 $ 1,007 $ — $ — Accrued and other current liabilities (58) (54) (99) (113) Pension and other postretirement benefits - noncurrent (5,925) (9,856) (1,152) (1,351) Net amount recognized $ (4,810) $ (8,903) $ (1,251) $ (1,464) Pretax amounts recognized in accumulated other comprehensive loss at Dec 31: Net loss (gain) $ 9,934 $ 12,736 $ (221) $ (129) Prior service credit (112) (154) — — Pretax balance in accumulated other comprehensive loss at end of year $ 9,822 $ 12,582 $ (221) $ (129) 1. The 2020 impact relates primarily to the transfer of benefit obligations in the U.S. through the purchase of annuity contracts from an insurance company. 2. The 2021 impact primarily relates to the freeze of pensionable compensation and credited service amounts for employees that participate in the U.S. Plans. The 2020 impact relates to pension plan curtailments of a European plan resulting from the 2020 Restructuring Program and the settlement of certain plan obligations of a U.S. non-qualified pension plan resulting from lump-sum payments. 3. The 2020 impact relates to the purchase of annuity contracts associated with the transfer of benefit obligations to an insurance company. A significant component of the overall decrease in the Company's benefit obligation for the year ended December 31, 2021 was due to the change in weighted-average discount rates, which increased from 2.20 percent at December 31, 2020 to 2.57 percent at December 31, 2021. A significant component of the overall increase in the Company's benefit obligation for the year ended December 31, 2020 was due to the change in weighted-average discount rates, which decreased from 2.81 percent at December 31, 2019 to 2.20 percent at December 31, 2020. The accumulated benefit obligation for all significant pension plans was $32.5 billion and $34.1 billion at December 31, 2021 and 2020, respectively.

The 2021 impact primarily relates to the freeze of pensionable compensation and credited service amounts for employees that participate in the U.S. Plans. The 2020 impact relates to pension plan curtailments of a European plan resulting from the 2020 Restructuring Program and the settlement of certain plan obligations of a U.S. non-qualified pension plan resulting from lump-sum payments. The 2019 impact relates to plan curtailments and associated special termination benefits resulting from the reduction in plan participation due to the separation from DowDuPont. 2. The 2019 impact is the result of the Company's separation from DowDuPont. Except for plan curtailment costs related to the 2020 Restructuring Program, which are included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income, non-service cost components of net periodic benefit cost are included in "Sundry income (expense) - net" in the consolidated statements of income. See Notes 6 and 7 for additional information. Estimated Future Benefit Payments The estimated future benefit payments of continuing operations, reflecting expected future service, as appropriate, are presented in the following table: Estimated Future Benefit Payments at Dec 31, 2021 Defined Benefit Pension Plans Other Postretirement Benefit Plans In millions 2022 $ 1,705 $ 100 2023 1,548 96 2024 1,551 92 2025 1,576 89 2026 1,593 87 2027-2031 8,093 386 Total $ 16,066 $ 850 Plan Assets Plan assets consist primarily of equity and fixed income securities of U.S. and foreign issuers, and include alternative investments, such as real estate, private equity and absolute return strategies. Plan assets totaled $28.2 billion at December 31, 2021 and $26.4 billion at December 31, 2020 and included no directly held common stock of Dow Inc. The Company's investment strategy for plan assets is to manage the assets in relation to the liability in order to pay retirement benefits to plan participants over the life of the plans. This is accomplished by identifying and managing the exposure to various market risks, diversifying investments across various asset classes and earning an acceptable long-term rate of return consistent with an acceptable amount of risk, while considering the liquidity needs of the plans. The plans are permitted to use derivative instruments for investment purposes, as well as for hedging the underlying asset and liability exposure and rebalancing the asset allocation. The plans use value-at-risk, stress testing, scenario analysis and Monte Carlo simulations to monitor and manage both the risk within the portfolios and the surplus risk of the plans. Equity securities primarily include investments in large- and small-cap companies located in both developed and emerging markets around the world. Fixed income securities include investment and non-investment grade corporate bonds of companies diversified across industries, U.S. treasuries, non-U.S. developed market securities, U.S. agency mortgage-backed securities, emerging market securities and fixed income related funds. Alternative investments primarily include investments in real estate, private equity and absolute return strategies. Other significant investment types include various insurance contracts and interest rate, equity, commodity and foreign exchange derivative investments and hedges. The Company mitigates the credit risk of investments by establishing guidelines with investment managers that limit investment in any single issue or issuer to an amount that is not material to the portfolio being managed. These guidelines are monitored for compliance both by the Company and external managers. Credit risk related to derivative activity is mitigated by utilizing multiple counterparties, collateral support agreements and centralized clearing, where appropriate. A short-term investment money market fund is utilized as the sweep vehicle for the U.S. plans, which from time to time can represent a significant investment. The weighted-average target allocation for plan assets of the Company's pension plans is summarized as follows: Target Allocation for Plan Assets at Dec 31, 2021 Target Allocation Asset Category Equity securities 33 % Fixed income securities 37 Alternative investments 28 Other investments 2 Total 100 % Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. For pension plan assets classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. For pension plan assets classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources. For other pension plan assets for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. For pension plan assets classified as Level 3 measurements, total fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity for the investment. Certain pension plan assets are held in funds where fair value is based on an estimated net asset value per share (or its equivalent) as of the most recently available fund financial statements which are received on a monthly or quarterly basis. These valuations are reviewed for reasonableness based on applicable sector, benchmark and company performance. Adjustments to valuations are made where appropriate to arrive at an estimated net asset value per share at the measurement date. These funds are not classified within the fair value hierarchy. The following table summarizes the bases used to measure the Company’s pension plan assets at fair value for the years ended December 31, 2021 and 2020: Basis of Fair Value Measurements Dec 31, 2021 Dec 31, 2020 In millions Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Cash and cash equivalents $ 1,463 $ 1,353 $ 110 $ — $ 1,298 $ 1,103 $ 195 $ — Equity securities: U.S. equity securities 1 $ 4,117 $ 4,097 $ 18 $ 2 $ 3,934 $ 3,911 $ 22 $ 1 Non - U.S. equity securities 4,559 3,935 620 4 5,186 4,213 964 9 Total equity securities $ 8,676 $ 8,032 $ 638 $ 6 $ 9,120 $ 8,124 $ 986 $ 10 Fixed income securities: Debt - government-issued $ 4,838 $ 242 $ 4,596 $ — $ 4,998 $ 128 $ 4,870 $ — Debt - corporate-issued 4,949 1,095 3,854 — 3,970 553 3,416 1 Debt - asset-backed 117 — 116 1 103 — 102 1 Total fixed income securities $ 9,904 $ 1,337 $ 8,566 $ 1 $ 9,071 $ 681 $ 8,388 $ 2 Alternative investments: Private markets $ 5 $ — $ — $ 5 $ 13 $ — $ — $ 13 Real estate 67 67 — — 51 51 — — Derivatives - asset position 399 2 397 — 697 2 695 — Derivatives - liability position (324) (2) (322) — (594) (1) (593) — Total alternative investments $ 147 $ 67 $ 75 $ 5 $ 167 $ 52 $ 102 $ 13 Other investments $ 1,068 $ 7 $ 1,061 $ — $ 472 $ 22 $ 448 $ 2 Subtotal $ 21,258 $ 10,796 $ 10,450 $ 12 $ 20,128 $ 9,982 $ 10,119 $ 27 Investments measured at net asset value: Hedge funds $ 1,312 $ 1,350 Private markets 3,857 3,135 Real estate 1,793 1,886 Total investments measured at net asset value $ 6,962 $ 6,371 Items to reconcile to fair value of plan assets: Pension trust receivables 2 $ 62 $ 66 Pension trust payables 3 (115) (159) Total $ 28,167 $ 26,406 1.

STOCK-BASED COMPENSATION (Notes

STOCK-BASED COMPENSATION (Notes)	12 Months Ended

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company provides stock-based compensation in the form of the Employee Stock Purchase Plan, which grants eligible employees the right to purchase shares of the Company's common stock at a discounted price. The Company also grants stock-based compensation to employees and non-employee directors under stock incentive plans, in the form of stock options, stock appreciation rights, PSUs and RSUs. In connection with the Merger, on August 31, 2017 ("Conversion Date"), all outstanding TDCC stock options and RSU awards were converted into stock options and RSU awards with respect to DowDuPont common stock. The stock options and RSU awards had the same terms and conditions under the applicable plans and award agreements prior to the Merger. All outstanding and nonvested PSU awards were converted into RSU awards with respect to DowDuPont common stock at the greater of the applicable performance target or the actual performance as of the effective time of the Merger. Changes in the fair value of liability instruments are recognized as compensation expense each quarter. TDCC and Historical DuPont did not merge their stock-based compensation plans as a result of the Merger. TDCC and Historical DuPont stock-based compensation plans were assumed by DowDuPont and continued in place with the ability to grant and issue DowDuPont common stock until separation. In connection with the separation on April 1, 2019, outstanding stock options, RSU and PSU awards were converted to Dow Inc. denominated awards under the “Employer Method,” or DowDuPont denominated awards under the “Shareholder Method,” and adjusted to maintain the intrinsic value of those awards before and after the date of the separation. In connection with the Corteva separation transaction on June 3, 2019, the outstanding DowDuPont denominated stock options, RSU and PSU awards were converted to Corteva and DuPont denominated awards and adjusted to maintain the intrinsic value of those awards before and after the date of the Corteva separation. The awards have the same terms and conditions under the applicable plans and award agreements prior to the separation transactions. The conversions of stock awards resulted in no incremental compensation expense. Approximately 5,000 employees were impacted by the conversion on April 1, 2019 in connection with Dow Inc.'s separation from DowDuPont. Approximately 4,000 employees were impacted by the conversion on June 3, 2019 in connection with the Corteva separation transaction. The total stock-based compensation expense included in continuing operations in the consolidated statements of income was $276 million, $171 million and $158 million in 2021, 2020 and 2019, respectively. The income tax benefits related to stock-based compensation arrangements were $62 million, $39 million and $36 million in 2021, 2020 and 2019, respectively. Amounts disclosed throughout the remainder of this footnote are inclusive of activity attributable to both continuing operations and discontinued operations, as the impact of discontinued operations is not significant. Accounting for Stock-Based Compensation The Company grants stock-based compensation awards that vest over a specified period or upon employees meeting certain performance and/or retirement eligibility criteria. The fair value of equity instruments issued to employees is measured on the grant date. The fair value of liability instruments (granted to executive employees subject to stock ownership requirements, that provide the recipient the option to elect to receive a cash payment equal to the value of the stock award on the date of delivery) is measured at the end of each quarter. The fair value of equity and liability instruments is expensed over the vesting period or, in the case of retirement, from the grant date to the date on which retirement eligibility provisions have been met and additional service is no longer required. The Company estimates expected forfeitures based on historical activity. The Company uses the Black-Scholes option valuation model to estimate the fair value of stock options. The weighted-average assumptions used to calculate total stock-based compensation are included in the following table: Weighted-Average Assumptions 2021 2020 2019 Dividend yield 4.86 % 5.80 % 5.10 % Expected volatility 33.40 % 26.70 % 26.10 % Risk-free interest rate 0.68 % 1.49 % 2.43 % Expected life of stock options granted during period (years) 6.25 6.1 6.1 The dividend yield assumption was equal to the dividend yield on the grant date, which reflected the Company's quarterly dividend payments of $0.70 per share in 2021, 2020 and 2019 on Dow Inc. Common Stock. The expected volatility assumptions for the 2021, 2020 and 2019 stock options were based on an equal weighting of the historical daily volatility for the expected term of the awards and current implied volatility from exchange-traded options. The expected volatility assumption for the market portion of the 2021, 2020 and 2019 PSU awards were based on historical daily volatility for the term of the award. The risk-free interest rate was based on the U.S. Treasury strip rates over the expected life of the 2021, 2020 and 2019 options. The expected life of stock options granted was based on an analysis of historical exercise patterns. Stock Incentive Plan The Company has historically granted equity awards under various plans (the "Prior Plans"). On February 9, 2012, the Board authorized The Dow Chemical Company 2012 Stock Incentive Plan (the "2012 Plan"), which was approved by stockholders at TDCC's annual meeting on May 10, 2012 ("2012 Plan Effective Date") and became effective on that date. On February 13, 2014, the Board adopted The Dow Chemical Company Amended and Restated 2012 Stock Incentive Plan (the "2012 Restated Plan"). The 2012 Restated Plan was approved by stockholders at TDCC's annual meeting on May 15, 2014, and became effective on that date. The Prior Plans were superseded by the 2012 Plan and the 2012 Restated Plan (collectively, the "2012 Plan"). Under the 2012 Plan, the Company granted options, RSUs, PSUs, restricted stock, stock appreciation rights and stock units to employees and non-employee directors, subject to an aggregate limit and annual individual limits. The terms of the grants were fixed at the grant date. TDCC's stock-based compensation programs were assumed by DowDuPont and continued in place with the ability to grant and issue DowDuPont common stock until separation. On April 1, 2019 ("Original Effective Date"), in connection with the separation, the Company adopted the 2019 Stock Incentive Plan (the "2019 Plan"). Under the 2019 Plan, the Company may grant stock options, RSUs, PSUs, stock appreciation rights and stock units to employees and non-employee directors until the tenth anniversary of the Original Effective Date, subject to an aggregate limit and annual individual limits. The terms of the grants are fixed at the grant date. At December 31, 2021, there were approximately 59 million shares of common stock available for grant under the 2019 Plan. Stock Options The Company grants stock options to certain employees, subject to certain annual and individual limits, with terms of the grants fixed at the grant date. The exercise price of each stock option equals the market price of the common stock on the grant date. Options vest from one year to three years and have a maximum term of ten years. The following table summarizes stock option activity for 2021: Stock Options 2021 Shares in thousands Shares Exercise Price 1 Outstanding at Jan 1, 2021 20,252 $ 47.44 Granted 1,309 $ 57.67 Exercised (5,179) $ 39.97 Forfeited/Expired (102) $ 60.36 Outstanding at Dec 31, 2021 16,280 $ 50.56 Remaining contractual life in years 4.65 Aggregate intrinsic value in millions $ 141 Exercisable at Dec 31, 2021 13,106 $ 49.96 Remaining contractual life in years 3.75 Aggregate intrinsic value in millions $ 128 1.

Difference between the market price at exercise and the price paid by the employee to exercise the options. Total unrecognized compensation cost related to unvested stock option awards of $5 million at December 31, 2021, is expected to be recognized over a weighted-average period of 1.47 years. Restricted Stock Units The Company grants RSUs to certain employees and non-employee directors. The grants vest after a designated period of time, generally three years for employees and two years for non-employee directors. The following table shows changes in nonvested RSUs: RSU Awards 2021 Shares in thousands Shares Grant Date Fair Value 1 Nonvested at Jan 1, 2021 3,007 $ 53.78 Granted 1,715 $ 57.96 Vested (1,063) $ 60.86 Canceled (116) $ 54.17 Nonvested at Dec 31, 2021 3,543 $ 53.67 1.

Includes the fair value of shares vested in prior years and delivered in the reporting year. In 2021, the Company did not settle any RSU's in cash (approximately 85,000 RSUs settled in cash for $4 million in 2020 and 341,000 RSUs settled in cash for $19 million in 2019). Total unrecognized compensation cost related to RSU awards of $71 million at December 31, 2021 is expected to be recognized over a weighted-average period of 1.64 years. At December 31, 2021, approximately 1.8 million RSUs with a grant date weighted-average fair value per share of $52.92 had previously vested, but were not issued. These shares are scheduled to be issued to employees within six months to three years or to non-employee directors upon retirement. Performance Stock Units The Company grants PSUs to certain employees. The grants vest when the Company attains specified performance targets, such as return on capital, cumulative cash from operations and relative total shareholder return, over a predetermined period, generally one year to three years. Performance and payouts are determined independently for each metric. Compensation expense related to PSU awards is recognized over the lesser of the service or performance period. Changes in the fair value of liability instruments are recognized as compensation expense each quarter. The following table shows the PSU awards granted: PSU Awards Target Shares Granted 1 Grant Date Fair Value 2 Shares in thousands Year Performance Period 2021 Jan 1, 2021 – Dec 31, 2023 1,223 $ 61.48 2020 Jan 1, 2020 – Dec 31, 2022 1,426 $ 48.35 2019 Apr 1, 2019 – Dec 31, 2021 1,173 $ 57.58 1.

Employee Stock Purchase Plan The Board unanimously approved the Dow Inc. 2021 Employee Stock Purchase Plan (the "2021 ESPP"), which was approved by the Company's stockholders at the 2021 Annual Meeting of Stockholders held on April 15, 2021. Under the 2021 ESPP offering, most employees were eligible to purchase shares of common stock of Dow Inc. valued at up to 10 percent of their annual total base salary or wages. The number of shares purchased was determined using the amount contributed by the employee divided by the plan price. The plan price of the stock was equal to 85 percent of the fair market value (closing price) of the common stock at June 1, 2021 (beginning) or December 3, 2021 (ending) of the offering period, whichever was lower. In 2021, employees subscribed to the right to purchase approximately 2.3 million shares at a weighted-average price of $45.11 per share, under the 2021 ESPP. The plan price was fixed upon the close of the offering period. The shares were delivered to employees in the fourth quarter of 2021.

Includes marketable securities with maturities of less than one year. Portfolio managers regularly review the Company’s holdings to determine if any investments in debt securities are other-than-temporarily impaired. The analysis includes reviewing the amount of the impairment, as well as the length of time it has been impaired. The credit rating of the issuer, current credit rating trends, the trends of the issuer’s overall sector, the ability of the issuer to pay expected cash flows and the length of time the security has been in a loss position are considered in determining whether unrealized losses represent an other-than-temporary impairment. The Company did not have any credit-related losses in 2021, 2020 or 2019. The following table provides the fair value and gross unrealized losses of the Company’s investments in debt securities that were deemed to be temporarily impaired at December 31, 2021 and 2020, aggregated by investment category: Temporarily Impaired Debt Securities at Less than 12 months 12 months or more Total Fair Unrealized Fair Unrealized Fair Value Unrealized Losses In millions 2021 Government debt 1 $ 295 $ (13) $ 151 $ (15) $ 446 $ (28) Corporate bonds 355 (17) 16 (3) 371 (20) Total temporarily impaired debt securities $ 650 $ (30) $ 167 $ (18) $ 817 $ (48) 2020 Government debt 1 $ 124 $ (3) $ 7 $ (7) $ 131 $ (10) Corporate bonds 55 (3) 12 (2) 67 (5) Total temporarily impaired debt securities $ 179 $ (6) $ 19 $ (9) $ 198 $ (15) 1.

The net unrealized loss recognized in earnings on equity securities totaled $13 million for the year ended December 31, 2021 ($32 million net unrealized gain for the year ended December 31, 2020). Investments in Equity Securities Dec 31, 2021 Dec 31, 2020 In millions Readily determinable fair value $ 20 $ 40 Not readily determinable fair value $ 209 $ 215 Risk Management The Company’s business operations give rise to market risk exposure due to changes in foreign exchange rates, interest rates, commodity prices and other market factors such as equity prices. To manage such risks effectively, the Company enters into hedging transactions, pursuant to established guidelines and policies that enable it to mitigate the adverse effects of financial market risk. Derivatives used for this purpose are designated as hedges per the accounting guidance related to derivatives and hedging activities, where appropriate. A secondary objective is to add value by creating additional non-specific exposure within established limits and policies; derivatives used for this purpose are not designated as hedges. The potential impact of creating such additional exposures is not material to the Company’s results. Accounting guidance requires companies to recognize all derivative instruments as either assets or liabilities at fair value. The Company’s risk management program for interest rate, foreign currency and commodity risks is based on fundamental, mathematical and technical models that take into account the implicit cost of hedging. Risks created by derivative instruments and the mark-to-market valuations of positions are strictly monitored at all times, using value-at-risk and stress tests. Counterparty credit risk arising from these contracts is not significant because the Company minimizes counterparty concentration, deals primarily with major financial institutions of solid credit quality, and the majority of its hedging transactions mature in less than three months. In addition, the Company minimizes concentrations of credit risk through its global orientation by transacting with large, internationally diversified financial counterparties. It is the Company’s policy to not have credit risk-related contingent features in its derivative instruments. No significant concentration of counterparty credit risk existed at December 31, 2021. The Company does not anticipate losses from credit risk, and the net cash requirements arising from counterparty risk associated with risk management activities are not expected to be material in 2022. The Company revises its strategies as market conditions dictate and management reviews its overall financial strategies and the impacts from using derivatives in its risk management program with the Company’s senior leadership who also reviews these strategies with the Dow Inc. Board and/or relevant committees thereof. Derivative Instruments The notional amounts of the Company's derivative instruments presented on a net basis at December 31, 2021 and 2020, were as follows: Notional Amounts - Net Dec 31, 2021 Dec 31, 2020 In millions Derivatives designated as hedging instruments Interest rate contracts $ 3,000 $ 612 Foreign currency contracts $ 5,300 $ 3,784 Derivatives not designated as hedging instruments Interest rate contracts $ 36 $ 94 Foreign currency contracts $ 8,234 $ 9,187 The notional amounts of the Company's commodity derivatives presented on a net basis at December 31, 2021 and 2020, were as follows: Commodity Notionals - Net Dec 31, 2021 Dec 31, 2020 Notional Volume Unit Derivatives designated as hedging instruments Hydrocarbon derivatives 9.7 10.9 million barrels of oil equivalent Derivatives not designated as hedging instruments Hydrocarbon derivatives 0.1 — million barrels of oil equivalent Power derivatives 3.3 — thousands of megawatt hours Maturity Dates of Derivatives Designated as Hedging Instruments Year Interest rate contracts 2023 Foreign currency contracts 2023 Commodity contracts 2023 Interest Rate Risk Management The main objective of interest rate risk management is to reduce the total funding cost to the Company and to alter the interest rate exposure to the desired risk profile. To achieve this objective, the Company hedges using interest rate swaps, “swaptions,” and exchange-traded instruments. Foreign Currency Risk Management The global nature of the Company's business requires active participation in the foreign exchange markets. The Company has assets, liabilities and cash flows in currencies other than the U.S. dollar. The primary objective of the Company's foreign currency risk management is to optimize the U.S. dollar value of net assets and cash flows. To achieve this objective, the Company hedges on a net exposure basis using foreign currency forward contracts, over-the-counter option contracts, cross-currency swaps and nonderivative instruments in foreign currencies. Exposures primarily relate to assets, liabilities and bonds denominated in foreign currencies, as well as economic exposure, which is derived from the risk that currency fluctuations could affect the dollar value of future cash flows related to operating activities. Commodity Risk Management The Company has exposure to the prices of commodities in its procurement of certain raw materials. The primary purpose of commodity hedging activities is to manage the price volatility associated with these forecasted inventory purchases. Derivatives Not Designated in Hedging Relationships Foreign Currency Contracts The Company also uses foreign exchange forward contracts, options and cross-currency swaps that are not designated as hedging instruments primarily to manage foreign currency exposure. Commodity Contracts The Company utilizes futures, options and swap instruments that are effective as economic hedges of commodity price exposures, but do not meet hedge accounting criteria for derivatives and hedging, to reduce exposure to commodity price fluctuations on purchases of raw materials and inventory. Interest Rate Contracts The Company uses swap instruments that are not designated as hedging instruments to manage interest rate exposures. The Company uses interest rate swaps, "swaptions," and exchange-traded instruments to accomplish this objective. Accounting for Derivative Instruments and Hedging Activities Cash Flow Hedges For derivatives that are designated and qualify as cash flow hedging instruments, the gain or loss on the derivative is recorded in AOCL; it is reclassified to income in the same period or periods that the hedged transaction affects income. The unrealized amounts in AOCL fluctuate based on changes in the fair value of open contracts at the end of each reporting period. The Company anticipates volatility in AOCL and net income from its cash flow hedges. The amount of volatility varies with the level of derivative activities and market conditions during any period. The portion of the mark-to-market effects of the foreign currency contracts is recorded in AOCL; it is reclassified to income in the same period or periods that the underlying item affects income. Commodity swaps, futures and option contracts with maturities of not more than 60 months are utilized and designated as cash flow hedges of forecasted commodity purchases. The designated portion of the mark-to-market effect of the cash flow hedge instrument is recorded in AOCL; it is reclassified to income in the same period or periods that the underlying commodity purchase affects income. Fair Value Hedges For interest rate instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedge item attributable to the hedged risk are recognized in current period income and reflected as “Interest expense and amortization of debt discount” in the consolidated statements of income, except for amounts excluded from the assessment of effectiveness that are recognized in earnings through an amortization approach. Net Foreign Investment Hedges The Company designates derivatives that qualify as effective net foreign investment hedges, the results of which are presented in the effect of derivative instruments table. The Company also utilizes non-derivative instruments as net foreign investment hedges. The Company had outstanding foreign-currency denominated debt designated as a hedge of net foreign investment of $174 million at December 31, 2021 ($194 million at December 31, 2020).

The Company's held-to-maturity securities primarily included treasury bills and time deposits. 2. The Company's investments in marketable securities are included in "Other current assets" in the consolidated balance sheets. 3. The Company's investments in debt securities, which are primarily available-for-sale, and equity securities are included in "Other investments" in the consolidated balance sheets. 4. U.S. Treasury obligations, U.S. agency obligations, U.S. agency mortgage-backed securities and other municipalities' obligations. 5. See Note 22 for the classification of derivatives in the consolidated balance sheets. 6. See Note 22 for information on fair value measurements of long-term debt. 7. Estimated liability for TDCC's guarantee of Sadara's debt which is included in "Other noncurrent obligations" in the consolidated balance sheets. See Note 16 for additional information. For assets and liabilities classified as Level 1 measurements (measured using quoted prices in active markets), total fair value is either the price of the most recent trade at the time of the market close or the official close price, as defined by the exchange on which the asset is most actively traded on the last trading day of the period, multiplied by the number of units held without consideration of transaction costs. For assets and liabilities classified as Level 2 measurements, where the security is frequently traded in less active markets, fair value is based on the closing price at the end of the period; where the security is less frequently traded, fair value is based on the price a dealer would pay for the security or similar securities, adjusted for any terms specific to that asset or liability, or by using observable market data points of similar, more liquid securities to imply the price. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance and quality checks. For derivative assets and liabilities, standard industry models are used to calculate the fair value of the various financial instruments based on significant observable market inputs, such as foreign exchange rates, commodity prices, swap rates, interest rates and implied volatilities obtained from various market sources. Market inputs are obtained from well-established and recognized vendors of market data and subjected to tolerance/quality checks. For all other assets and liabilities for which observable inputs are used, fair value is derived through the use of fair value models, such as a discounted cash flow model or other standard pricing models. See Note 22 for further information on the types of instruments used by the Company for risk management. There were no transfers between Levels 1 and 2 in the years ended December 31, 2021 and 2020. For liabilities classified as Level 3 measurements, the fair value is based on significant unobservable inputs including assumptions where there is little, if any, market activity. The fair value of the Company’s accrued liability related to the guarantee of Sadara's debt is in proportion to the Company's 35 percent ownership interest in Sadara. The estimated fair value of the guarantee was calculated using a "with" and "without" method. The fair value of the debt was calculated "with" the guarantee less the fair value of the debt "without" the guarantee. The "with" and "without" values were calculated using a discounted cash flow method based on contractual cash flows as well as projected prepayments made on the debt by Sadara. See Note 16 for further information on guarantees classified as Level 3 measurements. The following table summarizes the changes in fair value measurements using Level 3 inputs for the year ended December 31, 2021: Fair Value Measurements Using Level 3 Inputs for Accrued Liability of Sadara Guarantee 2021 In millions Balance at Jan 1 $ — Recognition of liability 1 (235) Gain included in earnings 2 15 Balance at Dec 31 $ (220) 1.

Fair Value Measurements on a Nonrecurring Basis The following table summarizes the bases used to measure certain assets at fair value on a nonrecurring basis in the consolidated balance sheets in 2021, 2020 and 2019: Basis of Fair Value Measurements on a Nonrecurring Basis at Dec 31 (Level 3) Total Losses In millions 2020 Assets at fair value: Long-lived assets and other assets $ 121 $ (245) 2019 Assets at fair value: Long-lived assets, other assets and equity method investments $ 162 $ (2,031) Goodwill $ — $ (1,039) 2021 Fair Value Measurements on a Nonrecurring Basis The Company's fair value measurements on a nonrecurring basis were insignificant in 2021. 2020 Fair Value Measurements on a Nonrecurring Basis As part of the 2020 Restructuring Program, the Company has or will shut down and write off several small manufacturing facilities and miscellaneous assets around the world. The assets associated with this plan were written down to zero. In addition, impairments of leased, non-manufacturing facilities, which were classified as Level 3 measurements, resulted in a write-down of right-of-use assets to a fair value of $110 million using unobservable inputs. The impairment charges related to the 2020 Restructuring Program, totaling $196 million, were included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Packaging & Specialty Plastics ($11 million), Industrial Intermediates & Infrastructure ($22 million), Performance Materials & Coatings ($116 million) and Corporate ($47 million). In 2020, the Company recognized impairment charges of $30 million related to the write-down of a non-manufacturing asset and certain corporate leased equipment and the write-off of a capital project. The assets, classified as Level 3 measurements, were valued at $11 million using unobservable inputs. The impairment charges were included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Performance Materials & Coatings ($15 million) and Corporate ($15 million). In 2020, the Company recognized an additional pretax impairment charge of $19 million related to capital additions made to a bio-ethanol manufacturing facility in Santa Vitoria, Minas Gerais, Brazil, which was impaired in 2017. The assets were written down to zero in 2020. The impairment charge was included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income and related to Packaging & Specialty Plastics. On September 29, 2020, the Company divested the bio-ethanol manufacturing facility. See Note 6 for additional information. 2019 Fair Value Measurements on a Nonrecurring Basis As part of the Synergy Program, the Company has or will shut down and write-off several small manufacturing facilities, non-manufacturing assets and certain corporate facilities around the world. In 2019, manufacturing facilities associated with this plan were written down to zero. In addition, impairments of leased, non-manufacturing facilities, which were classified as Level 3 measurements, resulted in a write-down of right-of-use assets to a fair value of $152 million using unobservable inputs. The impairment charges related to the Synergy Program, totaling $143 million, were included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Industrial Intermediates & Infrastructure ($2 million), Performance Materials & Coatings ($28 million) and Corporate ($113 million). In 2019, the Company recognized an additional pretax impairment charge of $44 million related to capital additions made to Santa Vitoria, which was impaired in 2017. The assets were written down to zero in 2019. The impairment charge was included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income and related to Packaging & Specialty Plastics. In 2019, the Company recognized impairment charges of $14 million related to non-manufacturing assets. The assets, classified as Level 3 measurements, were valued at $10 million using unobservable inputs. The impairment charges were included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Performance Materials & Coatings ($9 million) and Corporate ($5 million). In 2019, the Company recognized an impairment charge of $75 million resulting from the planned divestiture of its acetone derivatives business to ALTIVIA Ketones & Additives, LLC. The transaction closed on November 1, 2019 and included the Company's acetone derivatives related inventory and production assets, located in Institute, West Virginia, in addition to the site infrastructure, land and utilities. The assets, classified as Level 3 measurements and valued using unobservable inputs, were written down to zero in 2019, except for inventory, which was sold at the lower of cost or market. The impairment charge was included in "Restructuring, goodwill impairment and asset related charges - net" in the consolidated statements of income and related to Packaging & Specialty Plastics ($24 million) and Corporate ($51 million). In the fourth quarter of 2019, the Company performed its annual goodwill impairment testing utilizing a discounted cash flow methodology as its valuation technique. As a result, the Company determined the fair value of the C&PM reporting unit was lower than its carrying amount and recorded an impairment charge of $1,039 million, included in “Restructuring, goodwill impairment and asset related charges - net” in the consolidated statements of income and related to Performance Materials & Coatings. See Note 13 for additional information on the impairment charge. In the fourth quarter of 2019, the Company concluded that its equity method investment in Sadara, classified as a Level 3 measurement and valued using unobservable inputs, was other-than-temporarily impaired and written down to zero. Additionally, the Company reserved certain accounts and notes receivable and accrued interest balances due to uncertainty on the timing of collection. As a result, the Company recorded a $1,755 million charge related to Sadara.

VARIABLE INTEREST ENTITIES [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES Consolidated Variable Interest Entities ("VIEs") The Company holds a variable interest in the following joint ventures or entities for which it is the primary beneficiary: Asia Pacific Joint Ventures The Company has variable interests in two joint ventures that own and operate manufacturing and logistics facilities, which produce chemicals and provide services in Asia Pacific. The Company's variable interests in these joint ventures relate to arrangements between the joint ventures and the Company, involving the majority of the output on take-or-pay terms with pricing ensuring a guaranteed return to the joint ventures. The Company was a 50 percent indirect owner in a propylene oxide ("PO") manufacturing joint venture in Asia Pacific. The Company had a variable interest in this joint venture relating to arrangements between the joint venture and the Company involving the majority of the output on take-or-pay terms, with pricing ensuring a guaranteed return to the joint venture. On April 30, 2019, the Company executed an agreement to acquire full ownership in the PO manufacturing joint venture. The transaction closed on October 1, 2019, for a cash purchase price of $331 million. Approximately half of the purchase price was attributed to the Company’s proportionate equity interest in the entity that owned the PO manufacturing joint venture, which was accounted for under the equity method of accounting, and was classified as "Investments in and loans to nonconsolidated affiliates" in the consolidated statements of cash flows. The remaining $166 million was classified as "Purchases of noncontrolling interests" in the consolidated statements of cash flows. Ethylene Storage Joint Venture The Company has variable interests in a joint venture that provides ethylene storage in Alberta, Canada. The Company's variable interests relate to arrangements involving a majority of the joint venture's storage capacity on take-or-pay terms with pricing ensuring a guaranteed return to the joint venture; and favorably priced leases provided to the joint venture. The Company provides the joint venture with operation and maintenance services and utilities. Assets and Liabilities of Consolidated VIEs The Company's consolidated financial statements include the assets, liabilities and results of operations of VIEs for which the Company is the primary beneficiary. The other equity holders’ interests are reflected in "Net income attributable to noncontrolling interests" in the consolidated statements of income and "Noncontrolling interests" in the consolidated balance sheets. The following table summarizes the carrying amounts of these entities’ assets and liabilities included in the Company’s consolidated balance sheets at December 31, 2021 and 2020: Assets and Liabilities of Consolidated VIEs at Dec 31 In millions 2021 2020 Cash and cash equivalents $ 40 $ 26 Other current assets 40 44 Net property 184 232 Other noncurrent assets 15 17 Total assets 1 $ 279 $ 319 Current liabilities $ 37 $ 73 Long-term debt 3 6 Other noncurrent obligations 13 18 Total liabilities 2 $ 53 $ 97 1. All assets were restricted at December 31, 2021 and 2020. 2. All liabilities were nonrecourse at December 31, 2021 and 2020. Amounts presented in the consolidated balance sheets and the table above as restricted assets or nonrecourse obligations relating to consolidated VIEs at December 31, 2021 and 2020 are adjusted for intercompany eliminations. Nonconsolidated VIEs The Company holds a variable interest in the following entities for which the Company is not the primary beneficiary: Silicon Joint Ventures The Company holds minority voting interests in certain joint ventures that produce silicon inputs for the Company. These joint ventures operate under supply agreements that sell inventory to the equity owners using pricing mechanisms that guarantee a return, therefore shielding the joint ventures from the obligation to absorb expected losses. As a result of the pricing mechanisms of these agreements, these entities are determined to be VIEs. The Company is not the primary beneficiary, as it does not hold the power to direct the activities that most significantly impact the economic performance of these entities; therefore, the entities are accounted for under the equity method of accounting. The Company's maximum exposure to loss as a result of its involvement with these variable interest entities is determined to be the carrying value of the investment in these entities. At December 31, 2021, the Company's investment in these joint ventures was $110 million ($107 million at December 31, 2020), classified as "Investment in nonconsolidated affiliates" in the consolidated balance sheets, representing the Company's maximum exposure to loss.

Segment Reporting [Abstract]
Segments and Geographic Regions [Text Block]	SEGMENTS AND GEOGRAPHIC REGIONS Dow combines global breadth; asset integration and scale; focused innovation and materials science expertise; leading business positions; and environmental, social and governance (ESG) leadership to achieve profitable growth and deliver a sustainable future. The Company’s ambition is to become the most innovative, customer centric, inclusive and sustainable materials science company in the world. Dow’s portfolio of plastics, industrial intermediates, coatings and silicones businesses delivers a broad range of differentiated, science-based products and solutions for its customers in high-growth market segments, such as packaging, infrastructure, mobility and consumer applications. Dow operates 104 manufacturing sites in 31 countries and employs approximately 35,700 people. The Company conducts its worldwide operations through six global businesses which are organized into the following operating segments: Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure and Performance Materials & Coatings. Corporate contains the reconciliation between the totals for the operating segments and the Company's totals. The Company did not aggregate any operating segments when determining its reportable segments. The Company reports geographic information for the following regions: U.S. & Canada, Asia Pacific, Latin America and EMEAI. The Company transfers ethylene to its downstream derivative businesses at market prices. The Company also allocated costs previously assigned to AgCo and SpecCo ("stranded costs") to the operating segments. Dow’s measure of profit/loss for segment reporting purposes is Operating EBIT (for the years ended December 31, 2021 and 2020) and pro forma Operating EBIT (for the year ended December 31, 2019) as this is the manner in which the Company's chief operating decision maker ("CODM") assesses performance and allocates resources. The Company defines Operating EBIT as earnings (i.e., "Income (loss) from continuing operations before income taxes") before interest, excluding the impact of significant items. The Company defines pro forma Operating EBIT as earnings (i.e., "Income (loss) from continuing operations before income taxes") before interest, plus pro forma adjustments, excluding the impact of significant items. Operating EBIT and pro forma Operating EBIT by segment include all operating items relating to the businesses; items that principally apply to Dow as a whole are assigned to Corporate. The Company also presents pro forma net sales for the year ended December 31, 2019 in this footnote as it is included in management's measure of segment performance and is regularly reviewed by the CODM. Pro forma net sales includes the impact of various manufacturing, supply and service related agreements entered into with DuPont and Corteva in connection with the separation which provide for different pricing than the historical intercompany and intracompany pricing practices of TDCC and Historical DuPont. Corporate Profile Dow conducts its worldwide operations through global businesses which are reflected in the following reportable segments: Packaging & Specialty Plastics The Packaging & Specialty Plastics operating segment consists of two highly integrated global businesses: Hydrocarbons & Energy and Packaging and Specialty Plastics. The segment employs the industry’s broadest polyolefin product portfolio, supported by the Company’s proprietary catalyst and manufacturing process technologies. These differentiators, plus collaboration at the customer’s design table, enable the segment to deliver more reliable, durable, higher-performing solutions designed for recyclability and enhanced plastics circularity and sustainability. The segment serves customers, brand owners and ultimately consumers in key markets including food and specialty packaging; industrial and consumer packaging; health and hygiene; caps, closures and pipe applications; consumer durables; mobility and transportation; and infrastructure. This segment includes the results of The Kuwait Styrene Company K.S.C.C. and The SCG-Dow Group, as well as a portion of the results of EQUATE, The Kuwait Olefins Company K.S.C.C. ("TKOC"), Map Ta Phut and Sadara, all joint ventures of the Company. Industrial Intermediates & Infrastructure The Industrial Intermediates & Infrastructure operating segment consists of two customer-centric global businesses - Industrial Solutions and Polyurethanes & Construction Chemicals - that develop important intermediate chemicals that are essential to manufacturing processes, as well as downstream, customized materials and formulations that use advanced development technologies. These businesses primarily produce and market ethylene oxide and propylene oxide derivatives that are aligned to market segments as diverse as appliances, coatings, electronics, surfactants for cleaning and sanitization, infrastructure and oil and gas. The businesses' global scale and reach, world-class technology, research and development capabilities and materials science expertise enable the Company to be a premier solutions provider offering customers value-add sustainable solutions to enhance comfort, energy efficiency, product effectiveness and durability across a wide range of home comfort and appliance, building and construction, mobility and transportation, adhesive and lubricant applications, among others. This segment includes a portion of the Company's share of the results of EQUATE, TKOC, Map Ta Phut and Sadara. Performance Materials & Coatings The Performance Materials & Coatings operating segment includes industry-leading franchises that deliver a wide array of solutions into consumer, infrastructure and mobility end-markets. The segment consists of two global businesses: Coatings & Performance Monomers and Consumer Solutions. These businesses primarily utilize the Company's acrylics-, cellulosics- and silicone-based technology platforms to serve the needs of the architectural and industrial coatings; home care and personal care; consumer and electronics; mobility and transportation; industrial and chemical processing; and building and infrastructure end-markets. Both businesses employ materials science capabilities, global reach and unique products and technology to combine chemistry platforms to deliver differentiated, market-driven and sustainable innovations to customers. Corporate Corporate includes certain enterprise and governance activities (including insurance operations, environmental operations, etc.); non-business aligned joint ventures; non-business aligned litigation expenses; and discontinued or non-aligned businesses. Sales are attributed to geographic region based on customer location; long-lived assets are attributed to geographic region based on asset location.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements of Dow Inc. and TDCC were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the assets, liabilities, revenues and expenses of all majority-owned subsidiaries over which Dow exercises control and, when applicable, entities for which Dow has a controlling financial interest or is the primary beneficiary. Intercompany transactions and balances are eliminated in consolidation. Investments in nonconsolidated affiliates (20-50 percent owned companies or less than 20 percent owned companies over which significant influence is exercised) are primarily accounted for using the equity method. Effective April 1, 2019, Dow Inc. owns all of the outstanding common shares of TDCC. TDCC is deemed the predecessor to Dow Inc. and the historical results of TDCC are deemed the historical results of Dow Inc. for periods prior to and including March 31, 2019. As a result of the parent/subsidiary relationship between Dow Inc. and TDCC, and considering that the financial statements and disclosures of each company are substantially similar, the companies are filing a combined report for this Annual Report on Form 10-K. The information reflected in the report is equally applicable to both Dow Inc. and TDCC, except where otherwise noted. As of the effective date and time of the distribution, DowDuPont no longer beneficially owned any equity interest in Dow and no longer consolidated Dow and its consolidated subsidiaries into its financial results. The consolidated financial results of Dow for the applicable periods presented reflect the distribution of TDCC’s agricultural sciences business (“AgCo”) and specialty products business (“SpecCo”) as discontinued operations, as well as the receipt of Historical DuPont’s ethylene and ethylene copolymers businesses (other than its ethylene acrylic elastomers business) (“ECP”) as a common control transaction from the closing of the Merger on August 31, 2017 ("Merger Date"). See Note 3 for additional information. The Company conducts its worldwide operations through six global businesses which are organized into the following operating segments: Packaging & Specialty Plastics, Industrial Intermediates & Infrastructure and Performance Materials & Coatings. Corporate contains the reconciliation between the totals for the operating segments and the Company's totals. See Note 26 for additional information. From the Merger Date through the separation, transactions between DowDuPont, TDCC and Historical DuPont and their affiliates were treated as related party transactions. Transactions between TDCC and Historical DuPont primarily consisted of the sale and procurement of certain raw materials that were consumed in each company's manufacturing process. Transactions between TDCC and Dow Inc. are treated as related party transactions for TDCC. See Note 25 for additional information. Throughout this Annual Report on Form 10-K, unless otherwise indicated, amounts and activity are presented on a continuing operations basis. Except as otherwise indicated by the context, the term "Union Carbide" means Union Carbide Corporation and the term "Dow Silicones" means Dow Silicones Corporation, both wholly owned subsidiaries of the Company. Certain reclassifications of prior period amounts have been made to conform with the current year presentation.
Use of Estimates in Financial Statement Preparation	Use of Estimates in Financial Statement Preparation The preparation of financial statements in accordance with U.S. GAAP requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s consolidated financial statements include amounts that are based on management’s best estimates and judgments. Actual results could differ from those estimates.
Asbestos-Related Matters	Asbestos-Related Matters Accruals for asbestos-related matters, including defense and processing costs, are recorded based on an analysis of claim and resolution activity, defense spending, and pending and future claims. These accruals are assessed at each balance sheet date to determine if the asbestos-related liability remains appropriate. Accruals for asbestos-related matters are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent.” See Note 16 for additional information.
Legal Costs	Legal Costs
Foreign Currency Translation	Foreign Currency TranslationThe local currency has been primarily used as the functional currency throughout the world. Translation gains and losses of those operations that use local currency as the functional currency are included in the consolidated balance sheets in "Accumulated other comprehensive loss" ("AOCL"). For certain subsidiaries, the U.S. dollar is used as the functional currency. This occurs when the subsidiary operates in an economic environment where the products produced and sold are tied to U.S. dollar-denominated markets, or when the foreign subsidiary operates in a hyper-inflationary environment. Where the U.S. dollar is used as the functional currency, foreign currency translation gains and losses are reflected in income.
Environmental Matters	Environmental Matters Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. These accruals are adjusted periodically as assessment and remediation efforts progress or as additional technical or legal information becomes available. Accruals for environmental liabilities are included in the consolidated balance sheets in “Accrued and other current liabilities” and “Other noncurrent obligations” at undiscounted amounts. Accruals for related insurance or other third-party recoveries for environmental liabilities are recorded when it is probable that a recovery will be realized and are included in the consolidated balance sheets in “Accounts and notes receivable - Other” or "Noncurrent receivables." Environmental costs are capitalized if the costs extend the life of the property, increase its capacity and/or mitigate or prevent contamination from future operations. Environmental costs are also capitalized in recognition of legal asset retirement obligations resulting from the acquisition, construction and/or normal operation of a long-lived asset. Costs related to environmental contamination treatment and cleanup are charged to expense. Estimated future incremental operations, maintenance and management costs directly related to remediation are accrued when such costs are probable and reasonably estimable.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include time deposits and investments with maturities of three months or less at the time of purchase.
Financial Instruments Accounting, Policy	Financial Instruments The Company calculates the fair value of financial instruments using quoted market prices when available. When quoted market prices are not available for financial instruments, the Company uses standard pricing models with market-based inputs that take into account the present value of estimated future cash flows. The Company utilizes derivatives to manage exposures to foreign currency exchange rates, commodity prices and interest rate risk. The fair values of all derivatives are recognized as assets or liabilities at the balance sheet date. Changes in the fair values of these instruments are reported in income or AOCL, depending on the use of the derivative and whether the Company has elected hedge accounting treatment. Gains and losses on derivatives that are designated and qualify as cash flow hedging instruments are recorded in AOCL until the underlying transactions are recognized in income. Gains and losses on derivative and non-derivative instruments used as hedges of the Company’s net investment in foreign operations are recorded in AOCL as part of the cumulative translation adjustment. Gains and losses on derivatives designated and qualifying as fair value hedging instruments, as well as the offsetting losses and gains on the hedged items, are reported in income in the same accounting period. Derivatives not designated as hedging instruments are marked-to-market at the end of each accounting period with the results included in income.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value. The method of determining cost for each subsidiary varies among last-in, first-out (“LIFO”); first-in, first-out (“FIFO”); and average cost, and is used consistently from year to year. At December 31, 2021, approximately 27 percent, 65 percent and 8 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively. At December 31, 2020, approximately 30 percent, 58 percent and 12 percent of the Company's inventories were accounted for under the LIFO, FIFO and average cost methods, respectively. The Company routinely exchanges and swaps raw materials and finished goods with other companies to reduce delivery time, freight and other transportation costs. These transactions are treated as non-monetary exchanges and are valued at cost.
Property	PropertyLand, buildings and equipment are carried at cost less accumulated depreciation or amortization. Property under finance lease agreements is carried at the present value of lease payments over the lease term less accumulated amortization. Depreciation is based on the estimated service lives of depreciable assets and is calculated using the straight-line method. Fully depreciated assets are retained in property and accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts, and the net amounts, less proceeds from disposal, are included in income.
Impairment and Disposal of Long-Lived Assets	Impairment and Disposal of Long-Lived Assets The Company evaluates long-lived assets (property, finite-lived intangible assets and right-of-use assets) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When undiscounted future cash flows are not expected to be sufficient to recover an asset’s carrying amount, the asset is written down to its fair value based on bids received from third parties or a discounted cash flow analysis based on market participant assumptions. Long-lived assets to be disposed of by sale, if material, are classified as held for sale and reported at the lower of carrying amount or fair value less cost to sell, and depreciation/amortization is ceased. Long-lived assets to be disposed of other than by sale are classified as held and used until they are disposed of and reported at the lower of carrying amount or fair value, and depreciation/amortization is recognized over the remaining useful life of the assets.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets The Company records goodwill when the purchase price of a business combination exceeds the estimated fair value of net identified tangible and intangible assets acquired. Goodwill is tested for impairment at the reporting unit level annually in the fourth quarter, or more frequently when events or changes in circumstances indicate that the fair value of a reporting unit has more likely than not declined below its carrying value. When testing goodwill for impairment, the Company may first assess qualitative factors. If an initial qualitative assessment identifies that it is more likely than not that the fair value of a reporting unit is less than its carrying value, additional quantitative testing is performed. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, an impairment charge is recognized based on the difference between the reporting unit's carrying value and its fair value. The Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units.
Asset Retirement Obligations	Asset Retirement ObligationsThe Company records asset retirement obligations as incurred and reasonably estimable, including obligations for which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the Company. The fair values of obligations are recorded as liabilities on a discounted basis and are accreted over time for the change in present value. Costs associated with the liabilities are capitalized and amortized over the estimated remaining useful life of the asset, generally for periods of 10 years or less.
Investments	Investments Investments in debt securities, primarily held by the Company's insurance operations, are classified as trading, available-for-sale or held-to-maturity. Investments classified as trading are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Those classified as available-for-sale are reported at fair value with unrealized gains and losses recorded in AOCL. Those classified as held-to-maturity are recorded at amortized cost. The cost of investments sold is determined by FIFO or specific identification. Investments in equity securities with a readily determinable fair value are reported at fair value with unrealized gains and losses related to mark-to-market adjustments included in income. Equity securities without a readily determinable fair value are accounted for at cost, adjusted for impairments and observable price changes in orderly transactions. The Company routinely reviews its investments for declines in fair value below the cost basis. When events or changes in circumstances indicate the carrying value of an asset may not be recoverable, the security is written down, establishing a new cost basis.
Lessee, Leases [Policy Text Block]	Leases The Company determines whether a contract contains a lease at contract inception. A contract contains a lease if there is an identified asset and the Company has the right to control the asset. Operating lease right-of-use (“ROU”) assets represent the Company's right to use an underlying asset for the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses the incremental borrowing rate in determining the present value of lease payments, unless the implicit rate is readily determinable. If lease terms include options to extend or terminate the lease, the ROU asset and lease liability are measured based on the reasonably certain decision. Leases with a term of 12 months or less at the commencement date are not recognized on the balance sheet and are expensed as incurred. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for nearly all classes of leased assets for which the Company is the lessee. Additionally, for certain equipment leases, the portfolio approach is applied to account for the operating lease ROU assets and lease liabilities. In the consolidated statements of income, lease expense for operating lease payments is recognized on a straight-line basis over the lease term. For finance leases, interest expense is recognized on the lease liability and the ROU asset is amortized over the lease term. Some leasing arrangements require variable payments that are dependent upon usage or output, or may vary for other reasons, such as insurance or tax payments. Variable lease payments are recognized as incurred and are not presented as part of the ROU asset or lease liability. See Note 17 for additional information.
Revenue	Revenue The Company recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. See Note 4 for additional information.
Severance Costs	Severance Costs The Company routinely reviews its operations around the world in an effort to ensure competitiveness across its businesses and geographic regions. When the reviews result in a workforce reduction related to the shutdown of facilities or other optimization activities, severance benefits are provided to employees primarily under the Company’s ongoing benefit arrangements. These severance costs are accrued once management commits to a plan of termination and it becomes probable that employees will be entitled to benefits at amounts that can be reasonably estimated.
Integration and Separation Costs	Integration and Separation Costs The Company classifies expenses related to the Merger and separation as "Integration and separation costs" in the consolidated statements of income. Merger and separation related costs include: post-Merger integration expenses, costs incurred for the separation of AgCo and SpecCo and costs related to the integration of ECP. Integration and separation costs primarily consist of financial adviser, information technology, legal, accounting, consulting and other professional advisory fees associated with preparation and execution of these activities. Integration and separation costs related to the Merger and separation were completed as of December 31, 2020.
Income Taxes	Income Taxes The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities using enacted tax rates. The effect of a change in tax rates on deferred tax assets or liabilities is recognized in income in the period that includes the enactment date. The Company uses the portfolio approach for releasing income tax effects from AOCL. The Company recognizes the financial statement effects of an uncertain income tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company accrues for other tax contingencies when it is probable that a liability to a taxing authority has been incurred and the amount of the contingency can be reasonably estimated. The current portion of uncertain income tax positions is included in “Income taxes payable” and the long-term portion is included in “Other noncurrent obligations” in the consolidated balance sheets. Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.
Earnings per common share	Earnings per Common Share The calculation of earnings per common share is based on the weighted-average number of the Company's common shares outstanding for the applicable period. The calculation of diluted earnings per common share reflects the effect of all potential common shares that were outstanding during the respective periods, unless the effect of doing so is antidilutive.
