Significant Accounting Policies [Abstract]
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared by Eastman Chemical Company ("Eastman" or the "Company") in accordance and consistent with the accounting policies stated in the Company's 2022 Annual Report on Form 10-K , and should be read in conjunction with the consolidated financial statements in Part II, Item 8 of that report, with the exception of recently adopted accounting standards noted below. The December 31, 2022 financial position data included herein was derived from the consolidated financial statements included in the 2022 Annual Report on Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States ("GAAP"). In the opinion of management, the unaudited consolidated financial statements include all normal recurring adjustments necessary for the fair statement of the interim financial information in conformity with GAAP. These statements contain some amounts that are based upon management estimates and judgments. Future actual results could differ from such current estimates. The unaudited consolidated financial statements include assets, liabilities, revenues, and expenses of business ventures in which Eastman has a controlling interest. Eastman accounts for other joint ventures and investments where it exercises significant influence on the equity basis. Intercompany transactions and balances are eliminated in consolidation. Certain prior period data has been reclassified in the unaudited consolidated financial statements and accompanying footnotes to conform to current period presentation, including sales revenue, earnings before interest and taxes ("EBIT"), and goodwill related to the product moves announced in first quarter 2023. See Note 3, "Goodwill", and Note 14, "Segment Information", for more information. Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2021-08 Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers : On January 1, 2023, Eastman adopted prospectively this update, which requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 Revenue from Contracts with Customers , as if it had originated the contracts. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-01 Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method : On January 1, 2023, Eastman adopted this update which clarifies the guidance in Accounting Standards Codification ("ASC") 815 on fair value hedge accounting of interest rate risk for portfolios of financial assets. This ASU amends the guidance in ASU 2017-12 (released on August 28, 2017) that, among other things, established the "last-of-layer" method for making the fair value hedge accounting for these portfolios more accessible. ASU 2022-01 renames that method the "portfolio layer" method and addresses feedback from stakeholders regarding its application. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-02 Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures : On January 1, 2023, Eastman adopted this update which amends the requirements for accounting for credit losses under ASC 326, eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40, and enhances creditors' disclosure requirements related to loan refinancings and restructurings for borrowers experiencing financial difficulty. This ASU also amends the guidance on "vintage disclosures" to require disclosure of gross write-offs by year of origination. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-04 Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations : On January 1, 2023, Eastman adopted this update which requires the buyer in a supplier finance program to disclose qualitative and quantitative information about the program. Required disclosures include information about the key terms of the program, outstanding confirmed amounts as of the end of the period, a rollforward of such amounts during each annual period, and a description of where in the financial statements outstanding amounts are presented. This guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the disclosure of rollforward information, which is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The adoption did not have a significant impact on the Company's financial position, results of operations, or cash flows. The required disclosures are included as part of "Working Capital Management and Off Balance Sheet Arrangements" disclosure below. Accounting Standards Issued But Not Adopted as of March 31, 2023 ASU 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions : The Financial Accounting Standards Board ("FASB") issued this update in June 2022, which states that when measuring the fair value of an asset or a liability, a reporting entity should consider the characteristics of the asset or liability, including restrictions on the sale of the asset or liability, if a market participant also would take those characteristics into account. Key to that determination is the unit of account for the asset or liability being measured at fair value. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. Management does not expect that changes required by the new standard will have a significant impact on the Company's financial statements and related disclosures. Working Capital Management and Off Balance Sheet Arrangements The Company has an off balance sheet, uncommitted accounts receivable factoring program under which entire invoices may be sold, without recourse, to third-party financial institutions. Under these agreements, the Company sells the invoices at face value, less a transaction fee, which substantially equals the carrying value and fair value with no gain or loss recognized, and no credit loss exposure is retained. Available capacity under these agreements, which the Company uses as a routine source of working capital funding, is dependent on the level of accounts receivable eligible to be sold and the financial institutions' willingness to purchase such receivables. In addition, certain agreements also require that the Company continue to service, administer, and collect the sold accounts receivable at market rates. The total amounts sold under the program in first quarter 2023 and 2022 were $677 million and $502 million, respectively. The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. Under a supplier finance program, the Company's suppliers may voluntarily sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, regardless of whether the suppliers sell their receivables to the financial institution. The range of payment terms Eastman negotiates with suppliers are consistent, regardless of whether a supplier participates in the program. No fees are paid by Eastman for the supplier finance platform or services fees. Eastman or the financial institution may terminate the program at any time with immediate effect upon 90 days' notice. Confirmed obligations in the supplier finance program of $87 million and $100 million at March 31, 2023 and December 31, 2022, respectively, are included in "Payables and other current liabilities" on the Unaudited Consolidated Statements of Financial Position.

The carrying value of these euro-denominated borrowings have been designated as non-derivative net investment hedges of a portion of the Company's net investments in euro functional-currency denominated subsidiaries to offset foreign currency fluctuations. (2) Net proceeds from the bond issuance will be used to finance or refinance existing and future eligible green investment initiatives which contribute to Eastman's environmental sustainability strategy (a green bond). In March 2023, the Company issued $500 million aggregate principal amount of 5.75% notes due March 2033 in a registered public offering (the "2023 Notes"). Net proceeds from the 2023 Notes will be allocated to eligible projects to advance Eastman's sustainability goals of mitigating climate change, mainstreaming circular economy, and caring for society. Proceeds from the sale of the notes, net of original issue discounts, and issuance costs were $496 million. Credit Facility, Term Loans, and Commercial Paper Borrowings In first quarter 2023, the Company borrowed $300 million under a delayed draw two-year term loan (the "2024 Term Loan"), which was executed in fourth quarter 2022 . As of March 31, 2023, the 2024 Term Loan balance outstanding was $300 million with a variable interest rate of 6.07%. In 2022, the Company borrowed $500 million under a five-year term loan agreement (the "2027 Term Loan"). The 2027 Term Loan balance outstanding was $499 million at both March 31, 2023 and December 31, 2022, with variable interest rates of 5.92% and 5.55%, respectively. Borrowings under the 2024 Term Loan and 2027 Term Loan are subject to interest at varying spreads above quoted market rates. The Company has access to a $1.50 billion revolving credit agreement (the "Credit Facility") expiring December 2026 that was amended in March 2023. The amendment replaced the London Interbank Offered Rate-based ("LIBOR") reference interest rate option with a reference interest rate option based upon Term Secured Overnight Financing Rate ("SOFR") (as defined in the Credit Facility). All other material terms of the Credit Facility remain unchanged. Borrowings under the Credit Facility are subject to interest at varying spreads above quoted market rates and a commitment fee is paid on the total unused commitment. The Credit Facility includes sustainability-linked pricing terms, provides available liquidity for general corporate purposes, and supports commercial paper borrowings. Commercial paper borrowings are classified as short-term. At March 31, 2023 and December 31, 2022, the Company had no outstanding borrowings under the Credit Facility. At March 31, 2023, the Company had no outstanding commercial paper borrowings. At December 31, 2022, the Company's commercial paper borrowings were $326 million with a weighted average interest rate of 4.85%. The Credit Facility, the 2024 Term Loan, and the 2027 Term Loan contain customary covenants, including requirements to maintain certain financial ratios, that determine the events of default, amounts available, and terms of borrowings. The Company was in compliance with all applicable covenants at both March 31, 2023 and December 31, 2022. Fair Value of Borrowings Eastman has classified its total borrowings at March 31, 2023 and December 31, 2022 under the fair value hierarchy as defined in the accounting policies in Note 1, "Significant Accounting Policies", to the consolidated financial statements in Part II, Item 8 of the Company's 2022 Annual Report on Form 10-K . The fair value for fixed-rate debt securities is based on quoted market prices for the same or similar debt instruments and is classified as Level 2. The fair value for the Company's other borrowings, under the Term Loans and commercial paper, equals the carrying value and is classified as Level 2. At March 31, 2023 and December 31, 2022, the fair values of total borrowings were $5.5 billion and $4.9 billion, respectively. The Company had no borrowings classified as Level 1 and Level 3 as of March 31, 2023 and December 31, 2022.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVE AND NON-DERIVATIVE FINANCIAL INSTRUMENTS Overview of Hedging Programs Eastman is exposed to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. To mitigate these market risks and their effects on the cash flows of the underlying transactions and investments in foreign subsidiaries, the Company uses various derivative and non-derivative financial instruments, when appropriate, in accordance with the Company's hedging strategy and policies. Designation is performed on a specific exposure basis to support hedge accounting. The Company does not enter into derivative transactions for speculative purposes. For further information on hedging programs, see Note 10, "Derivative and Non-Derivative Financial Instruments", to the consolidated financial statements in Part II, Item 8 of the Company's 2022 Annual Report on Form 10-K . Cash Flow Hedges Cash flow hedges are derivative instruments designated as and used to hedge the exposure to variability in expected future cash flows that are attributable to a particular risk. The derivative instruments that are designated and qualify as a cash flow hedge are reported on the balance sheet at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated cash flows of the underlying exposures being hedged. The change in the hedge instrument is reported as a component of "Accumulated other comprehensive income (loss)" ("AOCI") on the Unaudited Consolidated Statements of Financial Position and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from cash flow hedges are classified as operating activities in the Unaudited Consolidated Statements of Cash Flows. Fair Value Hedges Fair value hedges are defined as derivative or non-derivative instruments designated as and used to hedge the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk. The derivative instruments that are designated and qualify as fair value hedges are reported as "Long-term borrowings" on the Unaudited Consolidated Statements of Financial Position at fair value and the changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the anticipated fair value of the underlying exposures being hedged. The net of the change in the hedge instrument and item being hedged for qualifying fair value hedges is recognized in earnings in the same period or periods during which the hedged transaction affects earnings. Cash flows from fair value hedges are classified as operating activities in the Unaudited Consolidated Statements of Cash Flows. Net Investment Hedges Net investment hedges are defined as derivative or non-derivative instruments designated as and used to hedge the foreign currency exposure of the net investments in certain foreign operations. The net of the change in the hedge instrument and item being hedged for qualifying net investment hedges is reported as a component of the "Cumulative Translation Adjustment" ("CTA") within AOCI on the Unaudited Consolidated Statements of Financial Position. Cash flows from the CTA component are classified as operating activities in the Unaudited Consolidated Statements of Cash Flows. Recognition in earnings of amounts previously recognized in CTA is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. In the event of a complete or substantially complete liquidation of the net investment, cash flows from net investment hedges are classified as investing activities in the Unaudited Consolidated Statements of Cash Flows. For derivative cross-currency interest rate swap net investment hedges, gains and losses representing hedge components excluded from the assessment of effectiveness are recognized in CTA within AOCI and recognized in earnings through the periodic swap interest accruals. The cross-currency interest rate swaps designated as net investment hedges are included as part of "Other long-term liabilities", "Other noncurrent assets", "Payables and other current liabilities", or "Other current assets" on the Unaudited Consolidated Statements of Financial Position. Cash flows from excluded components are classified as operating activities in the Unaudited Consolidated Statements of Cash Flows. In February 2023, Eastman entered into fixed-to-fixed cross-currency swaps and designated these swaps to hedge a portion of its net investment in a euro functional currency denominated subsidiary against foreign currency fluctuations. These contracts involve the exchange of fixed U.S. dollars with fixed euro interest payments periodically over the life of the contracts and an exchange of the notional amounts at maturity. The fixed-to-fixed cross-currency swap includes €283 million ($300 million) maturing March 2033. In February 2023, the Company also entered into a fixed-to-fixed cross-currency swap and designated the swap to hedge a portion of its net investment in a Japanese yen functional currency denominated subsidiary against foreign currency fluctuations. This contract involves the exchange of fixed U.S. dollars with fixed Japanese yen interest payments over the life of the contract and an exchange of the notional amounts at maturity. The fixed-to-fixed cross-currency swaps include ¥6.7 billion ($50 million) maturing March 2025. Summary of Financial Position and Financial Performance of Hedging Ins truments The following table presents the notional amounts outstanding at March 31, 2023 and December 31, 2022 associated with Eastman's hedging programs. Notional Outstanding March 31, 2023 December 31, 2022 Derivatives designated as cash flow hedges: Foreign Exchange Forward and Option Contracts (in millions) EUR/USD (in EUR) €515 €573 Commodity Forward and Collar Contracts Energy (in million british thermal units) 8 3 Derivatives designated as fair value hedges: Fixed-for-floating interest rate swaps (in millions) $75 $75 Derivatives designated as net investment hedges: Cross-currency interest rate swaps (in millions) EUR/USD (in EUR) €870 €587 JPY/USD (in JPY) ¥6,723 — Non-derivatives designated as net investment hedges: Foreign Currency Net Investment Hedges (in millions) EUR/USD (in EUR) €1,247 €1,247 Fair Value Measurements All the Company's derivative assets and liabilities are currently classified as Level 2. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs that are derived from or corroborated by observable market data such as interest rate yield curves and currency spot and forward rates. The fair value of commodity contracts is derived using forward curves supplied by an industry recognized and unrelated third party. In addition, on an ongoing basis, the Company compares a subset of its valuations against valuations received from counterparties to validate the accuracy of its standard pricing models. The Company had no derivatives classified as Level 3 as of March 31, 2023 and December 31, 2022. Counterparties to these derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance, and the Company diversifies its positions among such counterparties to reduce its exposure to counterparty risk and credit losses. The Company monitors the creditworthiness of its counterparties on an ongoing basis. The Company did not recognize a credit loss during first quarter 2023 or 2022. All the Company's derivative contracts are subject to master netting arrangements, or similar agreements, which provide for the option to settle contracts on a net basis when they settle on the same day and in the same currency. In addition, these arrangements provide for a net settlement of all contracts with a given counterparty in the event that the arrangement is terminated due to the occurrence of default or a termination event. The Company does not have any cash collateral due under such agreements. The Company has elected to present derivative contracts on a gross basis on the Unaudited Consolidated Statements of Financial Position. The following table presents the financial assets and liabilities valued on a recurring and gross basis and includes where the financial assets and liabilities are on the Unaudited Consolidated Statements of Financial Position as of March 31, 2023 and December 31, 2022.

These derivatives are not designated as hedges due to the short-term nature and the gains or losses on these derivatives are marked-to-market in line item "Other (income) charges, net" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. As a result of these derivatives, the Company recognized a net loss of $5 million during first quarter 2023, and did not recognize a gain or loss during first quarter 2022. Pre-tax monetized positions and mark-to-market gains and losses from raw materials and energy, currency, and certain interest rate hedges that were included in AOCI included net gains of $79 million and $134 million at March 31, 2023 and December 31, 2022, respectively. Gains in AOCI decreased between December 31, 2022 and March 31, 2023 primarily as a result of an increase in euro to U.S. dollar exchange rates. If recognized, approximately $1 million in pre-tax losses, as of March 31, 2023, would be reclassified into earnings during the next 12 months, including foreign exchange contracts prospectively dedesignated and monetized in fourth quarter 2022.

Accrual for Environmental Loss Contingencies Disclosure [Abstract]
Environmental Matters	ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS Certain Eastman manufacturing facilities generate hazardous and nonhazardous wastes, of which the treatment, storage, transportation, and disposal are regulated by various governmental agencies. In connection with the cleanup of various hazardous waste sites, the Company, along with many other entities, has been designated a potentially responsible party ("PRP") by the U.S. Environmental Protection Agency under the Comprehensive Environmental Response, Compensation and Liability Act, which potentially subjects PRPs to joint and several liability for certain cleanup costs. In addition, the Company will incur costs for environmental remediation and closure and post-closure under the federal Resource Conservation and Recovery Act. Reserves for environmental contingencies have been established in accordance with Eastman's policies described in Note 1, "Significant Accounting Policies", to the consolidated financial statements in Part II, Item 8 of the Company's 2022 Annual Report on Form 10-K . The resolution of uncertainties related to environmental matters may have a material adverse effect on the Company's consolidated results of operations in the period recognized. However, because of the availability of legal defenses, the Company's preliminary assessment of actions that may be required, and the extended period of time that the obligations are expected to be satisfied, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will have a material adverse effect on the Company's future overall financial position, results of operations, or cash flows. Environmental Remediation and Environmental Asset Retirement Obligations The Company's net environmental reserve for environmental contingencies, including remediation costs and asset retirement obligations, is included as part of "Other noncurrent assets", "Payables and other current liabilities", and "Other long-term liabilities" on the Unaudited Consolidated Statements of Financial Position as follows: (Dollars in millions) March 31, 2023 December 31, 2022 Environmental contingencies, current $ 15 $ 10 Environmental contingencies, long-term 260 264 Total $ 275 $ 274 Environmental Remediation Estimated future environmental expenditures for undiscounted remediation costs ranged from the best estimate or minimum of $243 million to the maximum of $455 million and from the best estimate or minimum of $245 million to the maximum of $457 million at March 31, 2023 and December 31, 2022, respectively. The best estimate or minimum estimated future environmental expenditures are considered to be probable and reasonably estimable. Reserves for environmental remediation include liabilities expected to be paid within approximately 30 years. The amounts charged to pre-tax earnings for environmental remediation and related charges are recognized in "Cost of sales" and "Other (income) charges, net" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Changes in the reserves for environmental remediation liabilities during first three months 2023 and full year 2022 are summarized below: (Dollars in millions) Environmental Remediation Liabilities Balance at December 31, 2021 $ 253 Changes in estimates recognized in earnings and other 6 Cash reductions (14) Balance at December 31, 2022 245 Changes in estimates recognized in earnings and other 1 Cash reductions (3) Balance at March 31, 2023 $ 243 Environmental Asset Retirement Obligations An asset retirement obligation is an obligation for the retirement of a tangible long-lived asset that is incurred upon the acquisition, construction, development, or normal operation of that long-lived asset. Environmental asset retirement obligations primarily consist of closure and post-closure costs. For sites that have environmental asset retirement obligations, the best estimate recognized to date for these environmental asset retirement obligation costs were $32 million and $29 million at March 31, 2023 and December 31, 2022, respectively. Non-Environmental Asset Retirement Obligations The Company has contractual asset retirement obligations not associated with environmental liabilities. Eastman's non-environmental asset retirement obligations are primarily associated with the future closure of leased manufacturing assets in Pace, Florida and Oulu, Finland. These non-environmental asset retirement obligations were $52 million and $51 million at March 31, 2023 and December 31, 2022, respectively, and are included in "Other long-term liabilities" on the Unaudited Consolidated Statements of Financial Position.

The Company did not repurchase shares in first quarter 2023. First quarter 2022 reflects 548,035 shares delivered as part of the accelerated share repurchase program the Company entered into in fourth quarter 2021 (the "2021 ASR").

SHARE BASED COMPENSATION AWARDS [Abstract]
Share-based Payment Arrangement [Text Block]	SHARE-BASED COMPENSATION AWARDSThe Company utilizes share-based awards under employee and non-employee director compensation programs. These share-based awards have included restricted and unrestricted stock, restricted stock units, stock options, and long-term performance shares. In first quarter 2023 and 2022, $22 million and $25 million, respectively, of compensation expense before tax were recognized in "Selling, general and administrative expenses" ("SG&A") in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings for all share-based awards of which $7 million and $8 million, respectively, was for stock options. The compensation expense is recognized over the substantive vesting period, which may be a shorter time period than the stated vesting period for qualifying termination eligible employees as defined in the award notices. For first quarter 2023 and 2022, $6 million and $7 million, respectively, of stock option compensation expense was recognized due to qualifying termination eligibility preceding the requisite service period. The impact on first quarter 2023 and 2022 net earnings of $16 million and $19 million, respectively, is net of deferred tax expense related to share-based award compensation for each period. Stock Option Grants In first quarter 2023 and 2022, the number of stock options granted under the 2021 Omnibus Stock Compensation Plan was approximately 399 thousand and 362 thousand, respectively. Options have an exercise price equal to the closing price of the Company's stock on the date of grant. The term of options is 10 years with vesting periods that vary up to three years. Vesting usually occurs ratably over the vesting period or at the end of the vesting period. The Company utilizes the Black Scholes Merton option valuation model which relies on certain assumptions to estimate an option's fair value. The assumptions used in the determination of fair value for stock options granted in first quarter 2023 and 2022 are provided in the table below: First Quarter Assumptions 2023 2022 Expected volatility rate 30.55% 28.69% Expected dividend yield 3.31% 2.46% Average risk-free interest rate 4.13% 1.93% Expected term years 6.4 6.4 The grant date exercise price and fair value of options granted during first quarter 2023 were $83.84 and $21.67, respectively, and first quarter 2022 were $120.80 and $28.07, respectively. For options unvested at March 31, 2023, $4 million in compensation expense will be recognized over the next three years. Other Share-Based Compensation Awards In addition to stock option grants, the Company has awarded long-term performance shares, restricted stock and restricted stock units, and stock appreciation rights. The long-term performance share awards are based upon actual return on capital compared to a target return on capital and total stockholder return compared to a peer group ranking by total stockholder return over a three year performance period and pay out in unrestricted shares of common stock at the end of the performance period. The awards are valued using a Monte Carlo Simulation based model and vest pro-ratably over the three year performance period. The number of long-term performance share target awards during first quarter 2023 and 2022 for the 2023-2025 and 2022-2024 periods was approximately 407 thousand and 288 thousand, respectively. The target shares awarded are assumed to vest at 100 percent of the established target. At the end of the three-year performance period, the actual number of shares awarded can range from zero to 250 percent of the target shares based on the award notice. The number of restricted stock unit awards, which pay out in unrestricted shares of common stock at the end of the vesting and performance (if any) period, during first quarter 2023 and 2022 were approximately 108 thousand and 71 thousand, respectively. The fair value of a restricted stock unit award is equal to the closing stock price of the Company's stock on the award date and normally vests over a period of three years. In first quarter 2023 and 2022, $15 million and $17 million, respectively, was recognized as compensation expense before tax for these other share-based awards and was included in the total compensation expense noted above for all share-based awards. The unrecognized compensation expense before tax for these same type awards at March 31, 2023 was approximately $117 million and will be recognized primarily over a period of three years. For additional information regarding share-based compensation plans and awards, see Note 18, "Share-Based Compensation Plans and Awards", to the consolidated financial statements in Part II, Item 8 of the Company's 2022 Annual Report on Form 10-K .

New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2021-08 Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers : On January 1, 2023, Eastman adopted prospectively this update, which requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 Revenue from Contracts with Customers , as if it had originated the contracts. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-01 Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method : On January 1, 2023, Eastman adopted this update which clarifies the guidance in Accounting Standards Codification ("ASC") 815 on fair value hedge accounting of interest rate risk for portfolios of financial assets. This ASU amends the guidance in ASU 2017-12 (released on August 28, 2017) that, among other things, established the "last-of-layer" method for making the fair value hedge accounting for these portfolios more accessible. ASU 2022-01 renames that method the "portfolio layer" method and addresses feedback from stakeholders regarding its application. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-02 Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures : On January 1, 2023, Eastman adopted this update which amends the requirements for accounting for credit losses under ASC 326, eliminates the accounting guidance on troubled debt restructurings for creditors in ASC 310-40, and enhances creditors' disclosure requirements related to loan refinancings and restructurings for borrowers experiencing financial difficulty. This ASU also amends the guidance on "vintage disclosures" to require disclosure of gross write-offs by year of origination. The adoption did not have a significant impact on the Company's financial statements and related disclosures. ASU 2022-04 Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations : On January 1, 2023, Eastman adopted this update which requires the buyer in a supplier finance program to disclose qualitative and quantitative information about the program. Required disclosures include information about the key terms of the program, outstanding confirmed amounts as of the end of the period, a rollforward of such amounts during each annual period, and a description of where in the financial statements outstanding amounts are presented. This guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the disclosure of rollforward information, which is effective for fiscal years beginning after December 15, 2023, with early adoption permitted. The adoption did not have a significant impact on the Company's financial position, results of operations, or cash flows. The required disclosures are included as part of "Working Capital Management and Off Balance Sheet Arrangements" disclosure below. Accounting Standards Issued But Not Adopted as of March 31, 2023 ASU 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions : The Financial Accounting Standards Board ("FASB") issued this update in June 2022, which states that when measuring the fair value of an asset or a liability, a reporting entity should consider the characteristics of the asset or liability, including restrictions on the sale of the asset or liability, if a market participant also would take those characteristics into account. Key to that determination is the unit of account for the asset or liability being measured at fair value. This guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years, with early adoption permitted. Management does not expect that changes required by the new standard will have a significant impact on the Company's financial statements and related disclosures.
Off-Balance-Sheet Credit Exposure, Policy	Working Capital Management and Off Balance Sheet Arrangements The Company has an off balance sheet, uncommitted accounts receivable factoring program under which entire invoices may be sold, without recourse, to third-party financial institutions. Under these agreements, the Company sells the invoices at face value, less a transaction fee, which substantially equals the carrying value and fair value with no gain or loss recognized, and no credit loss exposure is retained. Available capacity under these agreements, which the Company uses as a routine source of working capital funding, is dependent on the level of accounts receivable eligible to be sold and the financial institutions' willingness to purchase such receivables. In addition, certain agreements also require that the Company continue to service, administer, and collect the sold accounts receivable at market rates. The total amounts sold under the program in first quarter 2023 and 2022 were $677 million and $502 million, respectively. The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. Under a supplier finance program, the Company's suppliers may voluntarily sell receivables due from Eastman to a participating financial institution. Eastman's responsibility is limited to making payments on the terms originally negotiated with suppliers, regardless of whether the suppliers sell their receivables to the financial institution. The range of payment terms Eastman negotiates with suppliers are consistent, regardless of whether a supplier participates in the program. No fees are paid by Eastman for the supplier finance platform or services fees. Eastman or the financial institution may terminate the program at any time with immediate effect upon 90 days' notice. Confirmed obligations in the supplier finance program of $87 million and $100 million at March 31, 2023 and December 31, 2022, respectively, are included in "Payables and other current liabilities" on the Unaudited Consolidated Statements of Financial Position.
