SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Notes)	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Interim Financial Statements The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the interim consolidated financial statements reflect all adjustments (including normal recurring accruals) which are considered necessary for the fair statement of the results for the periods presented. Results from interim periods should not be considered indicative of results for the full year. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The interim consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Basis of Presentation Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical DuPont") each merged with subsidiaries of DowDuPont and, as a result, Historical Dow and Historical DuPont became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the Merger Agreement. Historical Dow was determined to be the accounting acquirer in the Merger. Except as otherwise indicated by the context, the term "Historical Dow" includes Historical Dow and its consolidated subsidiaries, "Historical DuPont" includes Historical DuPont and its consolidated subsidiaries, "Union Carbide" means Union Carbide Corporation, a wholly owned subsidiary of Historical Dow, and "Dow Silicones" means Dow Silicones Corporation, a wholly owned subsidiary of Historical Dow. Significant Accounting Policies The Company updated its accounting policy for leases since the issuance of its Annual Report on Form 10-K for the year ended December 31, 2018 as a result of the adoption of Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" in the first quarter of 2019. See Notes 2 and 15 for additional information. See Note 1, "Summary of Significant Accounting Policies," to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 for more information on DowDuPont's other significant accounting policies. Leases The Company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. 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 are included in "Deferred charges and other assets" on the consolidated balance sheets. Operating lease liabilities are included in "Accrued and other current liabilities" and "Other noncurrent obligations" on the consolidated balance sheets. Finance lease ROU assets are included in "Property" and the corresponding lease liabilities are included in "Long-term debt due within one year" and "Long-term debt" on the consolidated balance sheets. 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 liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide the lessor's implicit rate, the Company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. 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.

RECENT ACCOUNTING GUIDANCE

RECENT ACCOUNTING GUIDANCE	3 Months Ended
	Mar. 31, 2019
Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING GUIDANCE	RECENT ACCOUNTING GUIDANCE Recently Adopted Accounting Guidance In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from legacy U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance, "Revenue from Contracts with Customers (Topic 606)," issued in 2014. The Company adopted the new standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The Company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 "Leases". In addition, the Company has elected the package of practical expedients permitted under the transition guidance within the new standard which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. As an accounting policy election, the Company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and accounts for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the consolidated balance sheet: Summary of Changes to the Consolidated Balance Sheet As Reported Dec 31, 2018 Effect of Adoption of ASU 2016-02 Updated Jan 1, 2019 In millions Assets Net property $ 35,848 $ 9 $ 35,857 Deferred income tax assets $ 1,724 $ (24 ) $ 1,700 Deferred charges and other assets $ 2,476 $ 3,386 $ 5,862 Total other assets $ 94,197 $ 3,362 $ 97,559 Total Assets $ 188,030 $ 3,371 $ 191,401 Liabilities Long-term debt due within one year $ 637 $ 1 $ 638 Accrued and other current liabilities $ 7,943 $ 721 $ 8,664 Total current liabilities $ 24,715 $ 722 $ 25,437 Long-Term Debt $ 37,662 $ 8 $ 37,670 Other noncurrent obligations $ 6,988 $ 2,569 $ 9,557 Total other noncurrent liabilities $ 29,474 $ 2,569 $ 32,043 Stockholders' Equity Retained earnings 1 $ 30,536 $ 72 $ 30,608 DowDuPont's stockholders' equity $ 94,571 $ 72 $ 94,643 Total equity $ 96,179 $ 72 $ 96,251 Total Liabilities and Equity $ 188,030 $ 3,371 $ 191,401 1. The net impact to retained earnings was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction. The adoption of the new guidance did not have a material impact on the Company's consolidated statement of income and had no impact on the consolidation statement of cash flows. Accounting Guidance Issued But Not Adopted at March 31, 2019 In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which is part of the FASB disclosure framework project to improve the effectiveness of disclosures in the notes to the financial statements. The amendments in the new guidance remove, modify and add certain disclosure requirements related to fair value measurements covered in ASC 820, "Fair Value Measurement." The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for either the entire standard or only the requirements that modify or eliminate the disclosure requirements, with certain requirements applied prospectively, and all other requirements applied retrospectively to all periods presented. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract," which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350, "Intangibles - Goodwill and Other" to determine which implementation costs to capitalize as assets or expense as incurred. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and an entity can elect to apply the new guidance on a prospective or retrospective basis. The Company is currently evaluating the impact of adopting this guidance.

INTENDED BUSINESS SEPARATIONS

INTENDED BUSINESS SEPARATIONS	3 Months Ended

Business Combinations [Abstract]
Intended Business Separations	INTENDED BUSINESS SEPARATIONS As discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, DowDuPont previously announced its intent to separate into three independent publicly traded companies - one for each of its agriculture, materials science and specialty products businesses (the “Intended Business Separations” and the transactions to accomplish the Intended Business Separations, the “separations”). DowDuPont formed two wholly owned subsidiaries: Dow Inc. ("Dow", formerly known as Dow Holdings Inc.), to serve as a holding company for its materials science business, and Corteva, Inc., to serve as a holding company for its agriculture business. Following the separations, DowDuPont will continue to hold the specialty products business and operate as "DuPont". Effective as of 5:00 p.m. on April 1, 2019, DowDuPont completed the distribution of Dow. DowDuPont expects to complete the intended separation of Corteva on June 1, 2019. See Note 24 for additional information. Integration and Separation Costs The Company incurred "Integration and separation costs," of $813 million and $457 million for the three months ended March 31, 2019 and 2018, respectively, recorded in the consolidated statements of income. These costs primarily consisted of financial advisory, information technology, legal, accounting, consulting, and other professional advisory fees associated with the preparation and execution of activities related to the Merger, post-merger integration and separation, and the ownership restructure of Dow Silicones. Integration and separation costs related to post-Merger integration and Intended Business Separation activities are expected to continue to be significant throughout 2019.

REVENUE

REVENUE	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE Revenue Recognition The majority of the Company's revenue is derived from product sales. In the three months ended March 31, 2019 , 98 percent of the Company's sales related to product sales ( 98 percent in the three months ended March 31, 2018 ) with the remaining balance primarily related to licensing of patents and technologies and Historical Dow's insurance operations. Product sales consist of sales of the Company's products to manufacturers, distributors and farmers and considers order confirmations or purchase orders, which in some cases are governed by master supply agreements, to be contracts with a customer. The Company enters into licensing arrangements in which it licenses certain rights of its patents and technology to customers. Revenue from the Company's licenses for patents and technology is derived from sales-based royalties and licensing arrangements based on billing schedules established in each contract. Remaining Performance Obligations Remaining performance obligations represent the transaction price allocated to unsatisfied or partially unsatisfied performance obligations. At March 31, 2019 , the Company had remaining performance obligations related to material rights granted to customers for contract renewal options of $100 million ( $102 million at December 31, 2018) and unfulfilled performance obligations for the licensing of technology of $519 million ( $407 million at December 31, 2018). The Company expects revenue to be recognized for the remaining performance obligations over the next one to 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 and royalty payments that are deferred and recognized over the life of the contract, with remaining contract terms that range up to 22 years . The Company will have rights to future consideration for revenue recognized when product is delivered to the customer.

Europe, Middle East and Africa. Contract Balances 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 realized when the associated revenue is recognized under the contract. "Contract liabilities - current" primarily reflects deferred revenue from prepayments in the Agriculture segment for contracts with customers where the Company receives advance payments for product to be delivered in future periods. "Contract liabilities - noncurrent" includes advance payment for product 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. The Company classifies deferred revenue as current (12 months or less) or noncurrent based on the timing of when the Company expects to recognize revenue. Revenue recognized in the first three months of 2019 from amounts included in contract liabilities at the beginning of the period was approximately $525 million (approximately $640 million in the first three months of 2018). The increase in contract liabilities from December 31, 2018 to March 31, 2019 was primarily due to advanced payments received from customers for product supply agreements related to Agriculture and one customer related to Packaging & Specialty Plastics, partially offset by Agriculture seed deliveries to customers for the North America growing season, which were delayed due to weather conditions. In the first three months of 2019, the amount of contract assets reclassified to receivables as a result of the right to the transaction consideration becoming unconditional was insignificant (insignificant in the first three months of 2018). The Company did not recognize any asset impairment charges related to contract assets during the period.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES On December 22, 2017, the Tax Cuts and Jobs Act (“The Act”) was enacted. The Act reduces the U.S. federal corporate income tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax on earnings of foreign subsidiaries that were previously tax deferred, creates new provisions related to foreign sourced earnings, eliminates the domestic manufacturing deduction and moves towards a territorial system. At December 31, 2018, the Company had completed its accounting for the tax effects of The Act. • As a result of The Act, the Company remeasured its U.S. federal deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21 percent . In the first quarter of 2018, the Company recorded a charge of $17 million to “Provision for income taxes on continuing operations" in the consolidated statements of income to adjust the provisional amount related to the remeasurement of the Company's deferred tax balance. • In the first quarter of 2018, the Company recorded an indirect impact of The Act related to prepaid tax on the intercompany sale of inventory. The amount recorded related to the inventory was a $54 million charge to "Provision for income taxes on continuing operations." During the first and second quarters of 2019, in connection with the Intended Business Separations, the Company has and expects to continue repatriating certain funds from its foreign subsidiaries that are not needed to finance local operations or separation activities. During the three months ended March 31, 2019, the Company recorded a tax charge of $13 million associated with these repatriation activities to "Provision for income taxes on continuing operations." Beyond these expected repatriations, the Company is still asserting indefinite reinvestment related to certain investments in foreign subsidiaries. Each year the Company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the Company. As a result, there is an uncertainty in income taxes recognized in the Company’s financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. The ultimate resolution of such uncertainties is not expected to have a material impact on the Company's results of operations.

TRANSFERS OF FINANCIAL ASSETS	TRANSFERS OF FINANCIAL ASSETS Historical Dow sold trade accounts receivable of select North American entities and qualifying trade accounts receivable of select European entities on a revolving basis to certain multi-seller commercial paper conduit entities ("conduits"). The proceeds received were comprised of cash and interests in specified assets of the conduits (the receivables sold by Historical Dow) that entitled Historical Dow to the residual cash flows of such specified assets in the conduits after the commercial paper was repaid. Neither the conduits nor the investors in those entities had recourse to other assets of Historical Dow in the event of nonpayment by the debtors. In the fourth quarter of 2017, the Company suspended further sales of trade accounts receivable through these facilities and began reducing outstanding balances through collections of trade accounts receivable previously sold to such conduits. In September and October 2018, the North American and European facilities, respectively, were amended and the terms of the agreements changed from off-balance sheet arrangements to secured borrowing arrangements. See Note 13 for additional information on the secured borrowing arrangements.

If applicable, updates have been included in the respective section below. 2019 Activity In the first three months of 2019, Historical Dow redeemed an aggregate principal amount of $72 million of International Notes at maturity. In March 2019, Historical DuPont fully repaid $262 million of 5.75 percent coupon bonds at maturity. DowDuPont Notes In contemplation of the separations and distributions and in preparation to achieve the intended credit profiles of Corteva, Dow and DuPont, in the fourth quarter of 2018, DowDuPont consummated a public underwritten offer of eight series of senior unsecured notes (the "DowDuPont Notes") in an aggregate principal amount of $12.7 billion . The DowDuPont Notes are a senior unsecured obligation of the Company and will rank equally with the Company's future senior unsecured debt outstanding from time to time. On November 1, 2018, the Company announced a $3.0 billion share buyback program, which expired on March 31, 2019. In the first quarter of 2019, proceeds from the DowDuPont Notes were used to purchase $1.6 billion of shares. As a result, the share buyback program was complete at March 31, 2019. Historical Dow Committed Credit Facilities On March 9, 2019, Historical Dow renewed a $100 million Bilateral Revolving Credit Facility agreement, which has a maturity date in March 2020 and provides for interest at floating rates, as defined in the agreement. Historical Dow Term Loan Facility In connection with the ownership restructure of Dow Silicones on May 31, 2016, Dow Silicones incurred $4.5 billion of indebtedness under a certain third party credit agreement ("Historical Dow Term Loan Facility"). Historical Dow subsequently guaranteed the obligations of Dow Silicones under the Historical Dow Term Loan Facility and, as a result, the covenants and events of default applicable to the Historical Dow Term Loan Facility are substantially similar to the covenants and events of default set forth in Historical Dow's Five Year Competitive Advance and Revolving Credit Facility. In the second quarter of 2018, Dow Silicones exercised the 19 month extension option making amounts borrowed under the Historical Dow Term Loan Facility repayable on December 30, 2019. In addition, Dow Silicones amended the Historical Dow Term Loan Facility to include an additional two -year extension option, at Dow Silicones' election, upon satisfaction of certain customary conditions precedent. On April 5, 2019, Dow Silicones voluntarily repaid $2.0 billion of principal, which was classified as "Long-term debt due within one year" in the consolidated balance sheets at March 31, 2019 . Dow Silicones also intends to exercise the two -year extension option on the remaining principal balance of $2.5 billion . Historical DuPont Term Loan and Revolving Credit Facilities In March 2016, Historical DuPont entered into a credit agreement that provides for a three -year, senior unsecured term loan facility in the aggregate principal amount of $4.5 billion (as may be amended, from time to time, the "Historical DuPont Term Loan Facility") under which Historical DuPont may make up to seven term loan borrowings and amounts repaid or prepaid are not available for subsequent borrowings. The proceeds from the borrowings under the Historical DuPont Term Loan Facility were used for Historical DuPont's general corporate purposes including debt repayment, working capital and funding a portion of the Company's costs and expenses. At March 31, 2019, Historical DuPont had made six term loan borrowings in an aggregate principal amount of $3.0 billion and had unused commitments of $1.5 billion under the Historical DuPont Term Loan Facility. See Note 24 for further discussion on the repayment of the Historical DuPont Term Loan Facility in May 2019. Historical DuPont Repurchase Facility In February 2019, Historical DuPont entered into a new committed receivable repurchase facility of up to $1,300 million (the "2019 Repurchase Facility") which expires in December 2019. Under the 2019 Repurchase Facility, Historical DuPont may sell a portfolio of available and eligible outstanding customer notes receivables within the Agriculture segment to participating institutions and simultaneously agree to repurchase at a future date. The 2019 Repurchase Facility is considered a secured borrowing with the customer notes receivable inclusive of those that are sold and repurchased, equal to 105 percent of the outstanding amounts borrowed utilized as collateral. Borrowings under the 2019 Repurchase Facility have an interest rate of LIBOR plus 0.75 percent. At March 31, 2019, $20 million of notes receivable, recorded in "Accounts and notes receivable - Trade," were pledged as collateral against outstanding borrowings under the 2019 Repurchase Facility of $19 million , recorded in "Notes payable" in the consolidated balance sheets. Debt Covenants and Default Provisions There were no material changes to the debt covenants and default provisions related to DowDuPont's, Historical Dow's and Historical DuPont's outstanding Notes, long-term debt and primary, private credit agreements for the three months ended March 31, 2019. See Note 24 for details of actions taken to achieve credit profiles of DuPont, Corteva and Dow.

COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES Litigation Asbestos-Related Matters of Union Carbide Corporation A summary of Asbestos-Related Matters of Union Carbide Corporation can be found in Note 16 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 . 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 Since 2003, Union Carbide has engaged Ankura Consulting Group, LLC ("Ankura"), a third party actuarial specialist, to review Union Carbide's historical asbestos-related claim and resolution activity in order to assist Union Carbide's management in estimating the asbestos-related liability. Each year, Ankura has reviewed the claim and resolution activity to determine the appropriateness of updating the most recent Ankura study. Based on the December 2018 Ankura review, and Union Carbide's own review of the data, Union Carbide's total asbestos-related liability through the terminal year of 2049, including asbestos-related defense and processing costs, was $1,260 million at December 31, 2018 , and included in “Accrued and other current liabilities” and “Asbestos-related liabilities - noncurrent” in the consolidated balance sheets. Each quarter, Union Carbide reviews claims filed, settled and dismissed, as well as average settlement and resolution costs by disease category. Union Carbide also considers additional quantitative and qualitative factors such as the nature of pending claims, trial experience of Union Carbide and other asbestos defendants, current spending for defense and processing costs, significant appellate rulings and legislative developments, trends in the tort system, and their respective effects on expected future resolution costs. Union Carbide's management considers all these factors in conjunction with the most recent Ankura study and determines whether a change in the estimate is warranted. Based on Union Carbide's review of 2019 activity, it was determined that no adjustment to the accrual was required at March 31, 2019 . Union Carbide's asbestos related liability for pending and future claims and defense and processing costs was $1,243 million at March 31, 2019 . Approximately 17 percent of the recorded liability related to pending claims and approximately 83 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 and 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 A summary of the Dow Silicones Chapter 11 Related Matters can be found in Note 16 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018. Introduction In 1995, Dow Silicones, then a 50 :50 joint venture between Historical Dow 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 and provides a process for the satisfaction of commercial creditor claims in the Chapter 11 Proceeding. As of June 1, 2016, Dow Silicones is a wholly owned subsidiary of Historical Dow. 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”). Dow Silicones has an obligation to fund the Settlement Facility and the Litigation Facility over a 16 -year period, commencing at the Effective Date. At March 31, 2019 , Dow Silicones and its insurers have made life-to-date payments of $1,762 million to the Settlement Facility and the Settlement Facility reported an unexpended balance of $110 million . Dow Silicones' liability for breast implant and other product liability claims ("Implant Liability") was $263 million at March 31, 2019 and December 31, 2018 , of which $157 million at March 31, 2019 ( $111 million at December 31, 2018 ) was included in "Accrued and other current liabilities" and $106 million at March 31, 2019 ( $152 million at December 31, 2018 ) was included in "Other noncurrent obligations" in the consolidated balance sheets. 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 claim filing levels in the Settlement Facility will be similar to those in a prior settlement program, which management uses to estimate future claim filing levels for the Settlement Facility; 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. If Dow Silicones was ultimately required to fund the full liability up to the maximum capped value, the liability would be $2,148 million at March 31, 2019 . 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. The actual amount of interest that will ultimately be paid to these Commercial Creditors is uncertain due to pending litigation between Dow Silicones and the Commercial Creditors regarding the appropriate interest rates to be applied to outstanding obligations from the 1995 bankruptcy filing date through the Effective Date, as well as the presence of any recoverable fees, costs, and expenses. 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 May 10, 2017, the U.S. District Court for the Eastern District of Michigan entered a stipulated order resolving pending discovery motions and established a discovery schedule for the Commercial Creditors matter. As a result, Dow Silicones and its third party consultants conducted further analysis of the Commercial Creditors claims and defenses. This analysis indicated the estimated remaining liability to Commercial Creditors to be within a range of $77 million to $260 million . No single amount within the range appeared to be a better estimate than any other amount within the range. Therefore, Dow Silicones recorded the minimum liability within the range. At March 31, 2019 , the liability related to Dow Silicones' potential obligation to its Commercial Creditors in the Chapter 11 Proceeding was $83 million and is included in "Accrued and other current liabilities" in the consolidated balance sheets ( $82 million at December 31, 2018 ). The actual amount of interest that will be paid to these creditors is uncertain and will ultimately be resolved through continued proceedings in the District Court. Indemnifications In connection with the June 1, 2016 ownership restructure of Dow Silicones, Historical Dow is indemnified by Corning for 50 percent of future losses associated with certain pre-closing liabilities, including the Implant Liability and Commercial Creditors matters described above, 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. Indemnification assets were insignificant at March 31, 2019 ( zero at December 31, 2018 ). 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. Separation of Historical DuPont's Performance Chemicals Segment On July 1, 2015, Historical DuPont completed the separation of its Performance Chemicals segment through the spin-off of all of the issued and outstanding stock of The Chemours Company (the "Chemours Separation"). In connection with the Chemours Separation, Historical DuPont and The Chemours Company (“Chemours”) entered into a Separation agreement (as amended, the "Chemours Separation Agreement"). Pursuant to the Chemours Separation Agreement, Chemours indemnifies Historical DuPont against certain litigation, environmental, workers' compensation and other liabilities that arose prior to the Chemours Separation. The term of this indemnification is generally indefinite and includes defense costs and expenses, as well as monetary and non-monetary settlements and judgments. In connection with the recognition of liabilities related to these matters, Historical DuPont records an indemnification asset when recovery is deemed probable. At March 31, 2019 , the indemnification assets were $84 million included in "Accounts and notes receivable - Other" and $289 million included in "Noncurrent receivables" along with the corresponding liabilities of $84 million recorded in "Accrued and other current liabilities" and $289 million included in "Other noncurrent obligations" in the consolidated balance sheets. PFOA Liabilities Historical DuPont is a party to legal proceedings relating to the use of PFOA (collectively, perfluorooctanoic acids and its salts, including the ammonium salt) by its former Performance Chemicals segment. While it is reasonably possible that Historical DuPont could incur liabilities related to PFOA, any such liabilities are not expected to be material. Pursuant to the Chemours Separation Agreement discussed above, Historical DuPont is indemnified by Chemours for the PFOA matters discussed below and has recorded a total liability of $22 million and a total indemnification asset of $22 million at March 31, 2019 , primarily related to testing drinking water in and around certain Historical DuPont sites and offering treatment or an alternative supply of drinking water if tests indicate the presence of PFOA in drinking water at or greater than the national health advisory level established from time to time by the EPA. Leach Settlement and MDL Settlement Historical DuPont has residual liabilities under its 2004 settlement of a West Virginia state court class action, Leach v. DuPont, which alleged that PFOA from Historical DuPont’s former Washington Works facility had contaminated area drinking water supplies and affected the health of area residents. The settlement class has about 80,000 members. In addition to relief that was provided to class members years ago, the settlement requires Historical DuPont to continue providing PFOA water treatment to six area water districts and private well users and to fund, through an escrow account, up to $235 million for a medical monitoring program for eligible class members. At March 31, 2019 , approximately $2 million had been disbursed from the account since its establishment in 2012 and the remaining balance is approximately $1 million . The Leach settlement permits class members to pursue personal injury claims for six health conditions (and no others) that an expert panel appointed under the settlement reported in 2012 had a “probable link” (as defined in the settlement) with PFOA: pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol. After the expert panel reported its findings, approximately 3,550 personal injury lawsuits were filed in federal and state courts in Ohio and West Virginia and consolidated in multi-district litigation in the U.S. District Court for the Southern District of Ohio (“MDL”). The MDL was settled in early 2017 for $671 million in cash, with Chemours and Historical DuPont (without indemnification from Chemours) each paying half. Post-MDL Settlement PFOA Personal Injury Claims The MDL settlement did not resolve claims of plaintiffs who did not have claims in the MDL or whose claims are based on diseases first diagnosed after February 11, 2017. At March 31, 2019 , about 57 lawsuits were pending alleging personal injury, including kidney and testicular cancer, thyroid disease and ulcerative colitis, from exposure to PFOA through air or water, only three of which are not part of the MDL or were not otherwise filed on behalf of Leach class members. Other PFOA Actions Historical DuPont is a party to other PFOA lawsuits that do not involve claims for personal injury. Chemours, pursuant to the Chemours Separation Agreement, is defending and indemnifying with reservations Historical DuPont in these lawsuits. New York . Historical DuPont is a defendant in about 52 lawsuits, including a putative class action, brought by persons who live in and around Hoosick Falls, New York. These lawsuits assert claims for medical monitoring and property damage based on alleged PFOA releases from manufacturing facilities owned and operated by co-defendants in Hoosick Falls and allege that Historical DuPont and 3M supplied some of the materials used at these facilities. Historical DuPont is also one of more than ten defendants in a lawsuit brought by the Town of East Hampton, New York alleging PFOA and perfluorooctanesulfonic acid ("PFOS") contamination of the town’s well water. New Jersey . At December 31, 2018, two lawsuits were pending, one brought by a local water utility and the second a putative class action, against Historical DuPont alleging that PFOA from Historical DuPont’s former Chambers Works facility contaminated drinking water sources. The putative class action was dismissed without prejudice by the plaintiffs. In late March of 2019, the New Jersey State Attorney General (the “NJAG”) filed four lawsuits against Historical DuPont, Chemours, 3M and others alleging that former Historical DuPont operations at the Chambers Works, Pompton Lakes Works, Parlin and Repauno sites in New Jersey, caused damage to the State’s natural resources. Two of these lawsuits (those involving the Chambers Works and Parlin sites) allege contamination from per- and polyfluoroalkyl substances (“PFAS”). The lawsuit related to Parlin names an additional DowDuPont subsidiary. The Ridgewood Water District in New Jersey filed suit in the first quarter of 2019 against Historical DuPont alleging losses related to the investigation, remediation and monitoring of polyfluorinated surfactants (“PFS”), including PFOA, in water supplies. Alabama . Historical DuPont is one of more than thirty defendants in a lawsuit by a local water utility alleging contamination from perfluorinated chemicals and compounds (“PFCs”), including PFOA, used by co-defendant carpet manufacturers to make their products more stain and grease resistant. Ohio . Historical DuPont is a defendant in three lawsuits: an action by the State of Ohio based on alleged damage to natural resources, a putative nationwide class action brought on behalf of anyone who has detectable levels of perfluorinated chemicals, including PFOA, in their blood, and an action by the City of Dayton claiming losses related to the investigation, remediation and monitoring of PFAS, including PFOA, in water supplies. Other . Dozens of cases have been filed against 3M and other defendants primarily alleging property damage from contamination in connection with the use of firefighting foams that contain PFOS. At March 31, 2019, Historical DuPont was named in 4 of these cases. Historical DuPont did not make firefighting foam and has never made or supplied PFOS or products that contained PFOS. Chemours Separation Agreement Amendment Concurrent with the MDL Settlement, Historical DuPont and Chemours amended the Chemours Separation Agreement to provide for a limited sharing of potential future PFOA liabilities for a five -year period that began on July 6, 2017. During that five -year period, Chemours will annually pay the first $25 million of future PFOA liabilities and, if that amount is exceeded, Historical DuPont will pay any excess amount up to the next $25 million , with Chemours annually bearing any excess liabilities above that amount. At the end of the five -year period, this limited sharing agreement will expire, and Chemours’ indemnification obligations under the Chemours Separation Agreement will continue unchanged. As part of this amendment, Chemours also agreed that it would not contest its liability for PFOA liabilities on the basis of certain ostensible defenses it had previously raised, including defenses relating to punitive damages, and would waive any such defenses with respect to PFOA liabilities. Chemours has, however, retained defenses as to whether any particular PFOA claim is within the scope of the indemnification provisions of the Chemours Separation Agreement. There have been no charges incurred by Historical DuPont under this arrangement through March 31, 2019 . Fayetteville Works Facility, North Carolina Prior to the separation of Chemours, Historical DuPont introduced GenX as a polymerization processing aid and a replacement for PFOA at the Fayetteville Works facility in Bladen County, North Carolina. The facility is now owned and operated by Chemours, which continues to manufacture and use GenX. In 2017, the facility became and continues to be the subject of inquiries and government investigations relating to the alleged discharge of GenX and certain similar compounds into the air and Cape Fear River. In August 2017, the U.S. Attorney’s Office for the Eastern District of North Carolina served Historical DuPont with a grand jury subpoena for testimony and documents related to these discharges. Historical DuPont was served with additional subpoenas relating to the same issue and in the second quarter of 2018, received a subpoena expanding the scope to any PFCs discharged from the Fayetteville Works facility into the Cape Fear River. It is possible that these ongoing inquiries and investigations, including the grand jury subpoena, could result in penalties or sanctions, or that additional litigation will be instituted against Chemours, Historical DuPont, or both. At March 31, 2019 , several actions are pending in federal court against Chemours and Historical DuPont. One of these actions is a consolidated putative class action that asserts claims for medical monitoring and property damage on behalf of putative classes of property owners and residents in areas near or who draw drinking water from the Cape Fear River. Another action is a consolidated action brought by various North Carolina water authorities, including the Cape Fear Public Utility Authority and Brunswick County, that seek actual and punitive damages as well as injunctive relief. In addition, an action is pending in North Carolina state court on behalf of about 100 plaintiffs who own wells and property near the Fayetteville Works facility. The plaintiffs seek damages for nuisance allegedly caused by releases of certain PFCs from the site. While it is reasonably possible that Historical DuPont could incur liabilities related to the actions described above, any such liabilities are not expected to be material. Historical DuPont has an indemnification claim against Chemours with respect to current and future inquiries and claims, including lawsuits, related to the foregoing. At March 31, 2019 , Chemours, with reservations, is defending and indemnifying Historical DuPont in the pending civil actions. Other Litigation Matters In addition to the specific matters described above, Historical Dow and Historical DuPont are parties to a number of other claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, governmental regulation, 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. Historical Dow and Historical DuPont have active risk management programs 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. Gain Contingency - Historical Dow v. Nova Chemicals Corporation Patent Infringement Matter On December 9, 2010, Historical Dow filed suit in the Federal Court in Ontario, Canada ("Federal Court") alleging that Nova Chemicals Corporation ("Nova") was infringing Historical Dow's Canadian polyethylene patent 2,106,705. Nova counterclaimed on the grounds of invalidity and non-infringement. On June 29, 2017, the Federal Court issued a Confidential Supplemental Judgment, concluding that Nova must pay $645 million Canadian dollars (equivalent to $495 million U.S. dollars) to Historical Dow, plus pre- and post-judgment interest, for which Historical Dow received payment of $501 million from Nova on July 6, 2017. Although Nova is appealing portions of the damages judgment, certain portions of it are indisputable and will be owed to Historical Dow regardless of the outcome of any further appeals by Nova. At March 31, 2019 , Historical Dow had $341 million ( $341 million at December 31, 2018 ) included in "Other noncurrent obligations" in the consolidated balance sheets related to the disputed portion of the damages judgment. Historical Dow is confident of its chances of defending the entire judgment on appeal, particularly the trial court's determinations on important factual issues, which will be accorded deferential review on appeal. See Note 16 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2018 for additional information. 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. At March 31, 2019 , the Company had accrued obligations of $1,197 million for probable environmental remediation and restoration costs, including $213 million for the remediation of Superfund sites. These obligations are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the consolidated balance sheets. This is management’s current 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 and a half 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. 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. At December 31, 2018 , the Company had accrued obligations of $1,201 million for probable environmental remediation and restoration costs, including $210 million for the remediation of Superfund sites. Pursuant to the Chemours Separation Agreement, Historical DuPont is indemnified by Chemours for certain environmental matters, included in the liability of $1,197 million , that have an estimated liability of $185 million at March 31, 2019 , and a potential exposure that ranges up to approximately $355 million above the current accrual. As such, Historical DuPont has recorded an indemnification asset of $185 million corresponding to its accrual balance related to these matters at March 31, 2019 , including $35 million related to Superfund sites. Guarantees The following table provides a summary of the final expiration, maximum future payments and recorded liability reflected in the consolidated balance sheets for each type of guarantee: Guarantees Mar 31, 2019 Dec 31, 2018 In millions Final Expiration Maximum Future Payments Recorded Liability Final Expiration Maximum Future Payments Recorded Liability Historical Dow guarantees 2023 $ 4,514 $ 15 2023 $ 4,523 $ 25 Historical DuPont guarantees 2022 239 — 2022 255 — Total guarantees $ 4,753 $ 15 $ 4,778 $ 25 Guarantees Historical Dow and Historical DuPont (the "Subsidiaries") have entered into guarantee agreements arising in the ordinary course of business from relationships with customers and nonconsolidated affiliates when the Subsidiaries undertake an obligation to guarantee the performance of others (via delivery of cash or other assets) if specified triggering events occur. With guarantees, such as commercial or financial contracts, non-performance by the guaranteed party triggers the obligation of the Subsidiaries to make payments to the beneficiary of the guarantee. The majority of these guarantees relate to debt of nonconsolidated affiliates, which have expiration dates ranging from less than one year to less than four years, and trade financing transactions in Latin America, which typically expire within one year of inception. The Subsidiaries current expectation is that future payment or performance related to the non-performance of others is considered remote. Historical Dow has entered into guarantee agreements ("Guarantees") related to project financing for Sadara Chemical Company ("Sadara"), a nonconsolidated affiliate. The total of an Islamic bond and additional project financing (collectively “Total Project Financing”) obtained by Sadara is approximately $12.5 billion . Sadara had $11.7 billion of Total Project Financing outstanding at March 31, 2019 ( $11.7 billion at December 31, 2018 ). Historical Dow's guarantee of the Total Project Financing is in proportion to Historical Dow's 35 percent ownership interest in Sadara, or up to approximately $4.2 billion when the project financing is fully drawn. Sadara successfully completed an extensive operational testing program in December 2018, however, the Guarantees will be released upon the satisfactory fulfillment of certain project completion conditions, which is expected by the middle of 2019, and must occur no later than December 2020.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	LEASES The Company has operating and finance leases for sales and administrative offices, power plants, production facilities, warehouses and tanks for product storage, airplanes, railcars, motor vehicles, certain machinery and equipment, and information technology assets. The Company’s leases have remaining lease terms of 1 year to 50 years . For purposes of calculating operating lease liabilities, lease terms may be deemed to include options to extend the lease when it is reasonably certain that the Company will exercise those options. Some leasing arrangements require variable payments that are dependent on usage, output, or may vary for other reasons, such as insurance and tax payments. The variable lease payments are not presented as part of the initial ROU asset or lease liability. The Company's lease agreements do not contain any material restrictive covenants. The components of lease cost for operating and finance leases for the three months ended March 31, 2019 were as follows: Lease Cost Three Months Ended Mar 31, 2019 (In millions) Operating lease cost $ 201 Finance lease cost Amortization of right-of-use assets $ 41 Interest on lease liabilities 7 Total finance lease cost $ 48 Short-term lease cost $ 60 Variable lease cost 89 Sublease income (9 ) Total lease cost $ 389 New leases entered into during the three months ended March 31, 2019 were not considered material.

Subsequent Event [Line Items]
Subsequent Events [Text Block]	NOTE 24 - SUBSEQUENT EVENTS Dow Spin-off Effective as of 5:00 p.m. on April 1, 2019, DowDuPont completed the distribution of Dow. Additionally, Dow commenced trading “regular way” under the symbol “DOW” on the New York Stock Exchange on April 2, 2019. Prior to the commencement of trading on April 2, 2019, the stockholders of record of the Company as of the close of business on March 21, 2019 received one share of Dow Common Stock for every three shares of DowDuPont Common Stock held by such stockholders as of March 21, 2019. The Company did not issue fractional shares of Dow Common Stock in the Dow Distribution; the Company’s stockholders received cash in lieu of fractional shares. Immediately after the Dow Distribution, DowDuPont does not beneficially own any equity interest in Dow and will no longer consolidate Dow into its financial results. Beginning in the second quarter of 2019, Dow's historical financial results for periods prior to April 1, 2019 will be reflected in the Company's consolidated financial statements as discontinued operations. Dow represents approximately one-third of the Company's assets and just over half of the Company's net sales. In connection with the Distributions, the Company, Dow and Corteva (together, the “Parties” and each a “Party”) entered into certain agreements that will effect the separations, provide for the allocation of DowDuPont’s assets, employees, liabilities and obligations (including its investments, property, employee benefits and tax-related assets and liabilities) among the Company, Dow, and Corteva, and provide a framework for the Company’s relationship with Dow and Corteva following the separations and Distributions. Effective April 1, 2019, the Parties entered into the following agreements: • Separation and Distribution Agreement - The Parties entered into an agreement that sets forth, among other things, the agreements among the Parties regarding the principal transactions necessary to effect the Distributions. It also sets forth other agreements that govern certain aspects of the Parties’ ongoing relationships after the completion of the Distributions (the "Separation and Distribution Agreement"). • Tax Matters Agreement - The Parties entered into an agreement that governs their respective rights, responsibilities and obligations with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and other matters regarding taxes. • Employee Matters Agreement - The Parties entered into an agreement that identifies employees and employee-related liabilities (and attributable assets) to be allocated (either retained, transferred and accepted, or assigned and assumed, as applicable) to the Parties as part of the Distributions and describes when and how the relevant transfers and assignments will occur. • Intellectual Property Cross-License Agreements - DowDuPont entered into an Intellectual Property Cross-License Agreement with Dow (the “DowDuPont-Dow IP Cross-License Agreement”). In addition, Dow and Corteva entered into an Intellectual Property Cross-License Agreement (the “Dow-Corteva IP Cross-License Agreement”). The Intellectual Property Cross-License Agreements set forth the terms and conditions under which the applicable Parties may use in their respective businesses, following each of the Distributions, certain know-how (including trade secrets), copyrights, and software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement. In connection with the intended Corteva Distribution, the Company expects to enter into additional agreements, including an intellectual property cross-license agreement with Corteva. This agreement will set forth the terms and conditions under which the Company and Corteva may use, in their respective businesses following the Corteva Distribution, certain know-how (including trade secrets), copyrights, and software, and certain patents and standards, allocated to another Party pursuant to the Separation and Distribution Agreement. Actions to Achieve Credit Profiles of DuPont, Corteva and Dow On April 1, 2019, prior to consummating the Dow Distribution, the Company contributed $2,024 million in cash to Dow. On March 22, 2019, Historical DuPont issued notices of redemption in full of all of its outstanding notes (the “Make Whole Notes”) listed in the table below: In millions Amount 4.625% Notes due 2020 $ 474 3.625% Notes due 2021 296 4.250% Notes due 2021 163 2.800% Notes due 2023 381 6.500% Debentures due 2028 57 5.600% Senior Notes due 2036 42 4.900% Notes due 2041 48 4.150% Notes due 2043 69 Total $ 1,530 The Make Whole Notes were redeemed on April 22, 2019, at the make-whole redemption prices set forth in the respective Make Whole Notes. On and after the date of redemption, the Make Whole Notes were no longer deemed outstanding, interest on the Make Whole Notes ceased to accrue and all rights of the holders of the Make Whole Notes were terminated. On May 2, 2019, Historical DuPont terminated its Term Loan Facility and repaid the aggregate outstanding principal amount of $3 billion plus accrued and unpaid interest through and including May 1, 2019. In contemplation of the foregoing, effective May 2, 2019, the Company fully drew the two term loan facilities it entered into in the fourth quarter of 2018 (the “DWDP Term Loan Facilities” and together with the DowDuPont Notes, the “Financings”) in the aggregate principal amount of $3 billion . The Company funded the activities above with cash from operations and proceeds from the Financings.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2019
Leases [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Interim Financial Statements The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the interim consolidated financial statements reflect all adjustments (including normal recurring accruals) which are considered necessary for the fair statement of the results for the periods presented. Results from interim periods should not be considered indicative of results for the full year. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The interim consolidated financial statements include the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Basis of Presentation Effective August 31, 2017, pursuant to the merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of December 11, 2015, as amended on March 31, 2017 ("Merger Agreement"), The Dow Chemical Company ("Historical Dow") and E. I. du Pont de Nemours and Company ("Historical DuPont") each merged with subsidiaries of DowDuPont and, as a result, Historical Dow and Historical DuPont became subsidiaries of DowDuPont (the "Merger"). Prior to the Merger, DowDuPont did not conduct any business activities other than those required for its formation and matters contemplated by the Merger Agreement. Historical Dow was determined to be the accounting acquirer in the Merger. Except as otherwise indicated by the context, the term "Historical Dow" includes Historical Dow and its consolidated subsidiaries, "Historical DuPont" includes Historical DuPont and its consolidated subsidiaries, "Union Carbide" means Union Carbide Corporation, a wholly owned subsidiary of Historical Dow, and "Dow Silicones" means Dow Silicones Corporation, a wholly owned subsidiary of Historical Dow.
Lessee, Leases [Policy Text Block]	Leases The Company determines whether an arrangement is a lease at the inception of the arrangement based on the terms and conditions in the contract. 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 are included in "Deferred charges and other assets" on the consolidated balance sheets. Operating lease liabilities are included in "Accrued and other current liabilities" and "Other noncurrent obligations" on the consolidated balance sheets. Finance lease ROU assets are included in "Property" and the corresponding lease liabilities are included in "Long-term debt due within one year" and "Long-term debt" on the consolidated balance sheets. 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 liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide the lessor's implicit rate, the Company uses its incremental borrowing rate at the commencement date in determining the present value of lease payments. Lease terms include options to extend the lease when it is reasonably certain those options will be exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet, and lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component for all asset classes. 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.

RECENT ACCOUNTING GUIDANCE (Pol

RECENT ACCOUNTING GUIDANCE (Policies)	3 Months Ended

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Guidance In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, "Leases (Topic 842)," and associated ASUs related to Topic 842, which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance requires that a lessee recognize assets and liabilities for leases, and recognition, presentation and measurement in the financial statements will depend on its classification as a finance or operating lease. In addition, the new guidance requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting remains largely unchanged from legacy U.S. GAAP but does contain some targeted improvements to align with the new revenue recognition guidance, "Revenue from Contracts with Customers (Topic 606)," issued in 2014. The Company adopted the new standard in the first quarter of 2019, which allows for a modified retrospective transition approach, applying the new standard to all leases existing at the date of initial adoption. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statement as its date of initial application. The Company has elected to apply the transition requirements at the January 1, 2019 effective date rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods are not restated and continue to be reported in accordance with historic accounting under ASC 840 "Leases". In addition, the Company has elected the package of practical expedients permitted under the transition guidance within the new standard which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. As an accounting policy election, the Company chose to not apply the standard to certain existing land easements, excluded short-term leases (term of 12 months or less) from the balance sheet and accounts for nonlease and lease components in a contract as a single component for all asset classes. The following table summarizes the impact of adoption to the consolidated balance sheet: Summary of Changes to the Consolidated Balance Sheet As Reported Dec 31, 2018 Effect of Adoption of ASU 2016-02 Updated Jan 1, 2019 In millions Assets Net property $ 35,848 $ 9 $ 35,857 Deferred income tax assets $ 1,724 $ (24 ) $ 1,700 Deferred charges and other assets $ 2,476 $ 3,386 $ 5,862 Total other assets $ 94,197 $ 3,362 $ 97,559 Total Assets $ 188,030 $ 3,371 $ 191,401 Liabilities Long-term debt due within one year $ 637 $ 1 $ 638 Accrued and other current liabilities $ 7,943 $ 721 $ 8,664 Total current liabilities $ 24,715 $ 722 $ 25,437 Long-Term Debt $ 37,662 $ 8 $ 37,670 Other noncurrent obligations $ 6,988 $ 2,569 $ 9,557 Total other noncurrent liabilities $ 29,474 $ 2,569 $ 32,043 Stockholders' Equity Retained earnings 1 $ 30,536 $ 72 $ 30,608 DowDuPont's stockholders' equity $ 94,571 $ 72 $ 94,643 Total equity $ 96,179 $ 72 $ 96,251 Total Liabilities and Equity $ 188,030 $ 3,371 $ 191,401 1. The net impact to retained earnings was primarily a result of the recognition of a deferred gain associated with a prior sale-leaseback transaction. The adoption of the new guidance did not have a material impact on the Company's consolidated statement of income and had no impact on the consolidation statement of cash flows. Accounting Guidance Issued But Not Adopted at March 31, 2019 In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement," which is part of the FASB disclosure framework project to improve the effectiveness of disclosures in the notes to the financial statements. The amendments in the new guidance remove, modify and add certain disclosure requirements related to fair value measurements covered in ASC 820, "Fair Value Measurement." The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for either the entire standard or only the requirements that modify or eliminate the disclosure requirements, with certain requirements applied prospectively, and all other requirements applied retrospectively to all periods presented. The Company is currently evaluating the impact of adopting this guidance. In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract," which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350, "Intangibles - Goodwill and Other" to determine which implementation costs to capitalize as assets or expense as incurred. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted and an entity can elect to apply the new guidance on a prospective or retrospective basis. The Company is currently evaluating the impact of adopting this guidance.
