SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES (Notes)	9 Months Ended

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 2019 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 the items noted below. The December 31, 2019 financial position data included herein was derived from the consolidated financial statements included in the 2019 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 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, sales revenue, and expenses of all majority-owned subsidiaries and joint ventures in which a controlling interest is maintained. 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. Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2016-13 Financial Instruments - Credit Losses: On January 1, 2020, Eastman adopted this standard, and related releases, under the various required transition methods. The amendments require a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of allowances for credit losses valuation account. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The adoption of this standard did not result in a material impact on the Company's financial statements and related disclosures. ASU 2018-13 Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement: On January 1, 2020, Eastman adopted this standard that is a part of the Financial Accounting Standards Board's ("FASB") disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary changes applicable to Eastman in this update are the disclosures of fair value levels, assessment thereof, and transfers between those levels. The adoption under the various required transition methods did not impact the Company's related disclosures. ASU 2018-18 Collaborative Arrangements - Clarifying the Interaction between Topic 808 (Collaborative Arrangements) and Topic 606 (Revenue from Contracts with Customers): On January 1, 2020, Eastman adopted this standard, retrospectively to the date of the initial application of Topic 606 on January 1, 2017, that provides clarification in regards to which contracts are accounted for under Topic 808 and Topic 606 as well as alignment of guidance between the two pronouncements. The adoption of this standard did not impact the Company's financial statements and related disclosures. ASU 2019-01 Leases - Codification Improvements: On January 1, 2020, Eastman adopted this standard which was applied as of the adoption date and under the same transition methodology of ASU 2016-02 Lease previously adopted on January 1, 2019. The FASB issued this update in response to stakeholder inquiries regarding the new leasing standard. The adoption of this standard did not impact the Company's financial statements and related disclosures. ASU 2020-04 Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting : Eastman adopted this standard when issued and effective on March 12, 2020. The FASB issued this update to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform (the global financial markets transition in contracts, hedging relationships, and other transactions away from referencing the London Interbank Offered Rate (LIBOR) and other interbank offered rates and toward new reference rates) on financial reporting. As reference reform has not impacted Eastman as of the issuance and effective date, the adoption of this standard did not impact the Company's financial statements and related disclosures. Accounting Standards Issued But Not Adopted as of September 30, 2020 ASU 2018-14 Retirement Benefits - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary change impacting Eastman is the addition of disclosures related to significant gains and losses related to changes in the benefit obligation for the period and weighted-average interest crediting rates for cash balance plans. This standard is effective for fiscal years ending after December 15, 2020. Upon adoption, this update is to be applied on a retrospective basis to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes : In December 2019, the FASB issued this update as part of its initiative to reduce complexity in accounting standards which removes certain exceptions and provides simplification to specific tax items. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. Management is currently evaluating the impact on the Company's financial statements and related disclosures. ASU 2020-01 Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815: In January 2020, the FASB issued a clarification that an entity should consider observable transactions that require the application or discontinuance of the equity method of accounting for the purposes of applying the measurement alternative and clarification that certain forward contracts and purchased options to purchase securities that, upon settlement, would be accounted for under the equity method of accounting. This standard is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. The update is to be applied prospectively. Management does not expect that changes required by the new standard will materially impact the Company's financial statements and related disclosures. Working Capital Management and Off Balance Sheet Arrangements Since 2019, the Company has been expanding its 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 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 in third quarter 2020 and 2019 were $336 million and $190 million, respectively, and $1.20 billion and $460 million in first nine months 2020 and 2019, respectively. The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. As part of these efforts, in 2019 the Company introduced a voluntary supply chain finance program to provide suppliers with the opportunity to 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. All of Eastman's accounts payable and associated payments are reported consistently in the Company's Unaudited Consolidated Statements of Financial Position and Unaudited Consolidated Statements of Cash Flows regardless of whether they are associated with a vendor who participates in the program.

At September 30, 2020 and December 31, 2019, Eastman had $194 million and $202 million, respectively, in unrecognized tax benefits. At September 30, 2020, it is reasonably possible that, as a result of the resolution of federal, state, and foreign examinations and appeals, and the expiration of various statutes of limitation, the total amounts of unrecognized tax benefits could decrease by $10 million to $55 million within the next 12 months.

BORROWINGS	BORROWINGS September 30, December 31, (Dollars in millions) 2020 2019 Borrowings consisted of: 4.5% notes due January 2021 (1) $ 185 $ 185 3.5% notes due December 2021 298 298 3.6% notes due August 2022 743 741 1.50% notes due May 2023 (2) 876 840 7 1/4% debentures due January 2024 198 198 7 5/8% debentures due June 2024 43 43 3.8% notes due March 2025 701 695 1.875% notes due November 2026 (2) 581 556 7.60% debentures due February 2027 195 195 4.5% notes due December 2028 493 493 4.8% notes due September 2042 493 493 4.65% notes due October 2044 874 874 Commercial paper and short-term borrowings 185 171 Total borrowings 5,865 5,782 Borrowings due within one year 370 171 Long-term borrowings $ 5,495 $ 5,611 (1) In October 2020, the Company repaid the 4.5% notes due January 2021 ($185 million principal) using available cash. (2) The carrying value of the euro-denominated 1.50% notes due May 2023 and 1.875% notes due November 2026 will fluctuate with changes in the euro exchange rate. 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. Loan Agreement, Credit Facility, and Commercial Paper Borrowings In second quarter 2020, the Company borrowed $250 million under a new 364-Day Term Loan Credit Agreement (the "Term Loan") as a precautionary measure due to increased financial market volatility, particularly in the availability and terms of commercial paper, resulting from the COVID-19 coronavirus global pandemic ("COVID-19"). In third quarter 2020, the Term Loan was repaid using available cash. The early repayment resulted in a charge of $1 million for early debt extinguishment costs which was primarily attributable to related unamortized issuance costs. The Company has access to a $1.50 billion revolving credit agreement (the "Credit Facility") expiring October 2023. 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 provides available liquidity for general corporate purposes and supports commercial paper borrowings. Commercial paper borrowings are classified as short-term. In first quarter 2020, the Company borrowed a total of $400 million under the Credit Facility. In second quarter 2020, the Company repaid a total of $400 million using available cash. At September 30, 2020 and December 31, 2019, the Company had no outstanding borrowings under the Credit Facility. At September 30, 2020, the Company's commercial paper borrowings were $185 million with a weighted average interest rate of 0.35 percent. At December 31, 2019, the Company's commercial paper borrowings were $170 million with a weighted average interest rate of 2.03 percent. The Credit Facility contains customary covenants, including requirements to maintain certain financial ratios, that determine the events of default, amounts available, and terms of borrowings. In second quarter 2020, the Company amended the Credit Facility and the Term Loan maximum debt covenants to reflect the higher cash balance to enhance liquidity due to, and the expected negative impact on operating results of, COVID-19 and added a new restrictive covenant prohibiting stock repurchases until June 30, 2021 in the event certain financial ratios are exceeded. The Company was in compliance with all applicable covenants at both September 30, 2020 and December 31, 2019. The Company did not renew the $250 million accounts receivable securitization agreement (the "A/R Facility") which expired April 2020. Eastman Chemical Financial Corporation ("ECFC"), a subsidiary of the Company, had an agreement to sell interests in trade receivables under the A/R Facility to a third party purchaser. Third party creditors of ECFC had first priority claims on the assets of ECFC before those assets would be available to satisfy the Company's general obligations. Borrowings under the A/R Facility were subject to interest rates based on a spread over the lender's borrowing costs and ECFC paid a fee to maintain availability of the A/R Facility. In first quarter 2020, the Company borrowed a total of $350 million, in two tranches, under the A/R Facility and repaid a total of $350 million using available cash. At December 31, 2019, the Company had no borrowings outstanding under the A/R Facility. Fair Value of Borrowings Eastman has classified its total borrowings at September 30, 2020 and December 31, 2019 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 2019 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, primarily under the Credit Facility and commercial paper, equals the carrying value and is classified as Level 2. At September 30, 2020 and December 31, 2019, the fair value of total borrowings was $6.529 billion and $6.275 billion, respectively. The Company had no borrowings classified as Level 3 as of September 30, 2020 and December 31, 2019.

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 9, "Derivative and Non-Derivative Financial Instruments", to the consolidated financial statements in Part II, Item 8 of the Company's 2019 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") located in 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. In first, second, and third quarters 2020, Eastman entered into forward-starting interest rate swaps with a notional amount of $25 million in each period to mitigate the risk of variability in interest rates for an expected long-term debt issuance by August 2022. These swaps were designated as cash flow hedges and will be settled upon debt issuance. The total outstanding forward starting swaps as of September 30, 2020 was $75 million. 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 recognized 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 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 in 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" within 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 September 2020, the Company terminated fixed-to-fixed cross-currency swaps designated to hedge a portion of its net investment in a euro functional currency denominated subsidiary against foreign currency fluctuations. The notional amount terminated was €150 million ($180 million) which was scheduled to mature in January 2021. The termination resulted in a $3 million gain recognized in CTA. The related cash flows were classified as investing activities in the Unaudited Consolidated Statements of Cash Flows. In September 2020, the Company 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 swaps include €152 million ($180 million) maturing December 2028. Summary of Financial Position and Financial Performance of Hedging Instruments The following table presents the notional amounts outstanding at September 30, 2020 and December 31, 2019 associated with Eastman's hedging programs. Notional Outstanding September 30, 2020 December 31, 2019 Derivatives designated as cash flow hedges: Foreign Exchange Forward and Option Contracts (in millions) EUR/USD (in EUR) €549 €630 Commodity Forward and Collar Contracts Feedstock (in million barrels) — 1 Energy (in million british thermal units) 22 27 Interest rate swaps for the future issuance of debt (in millions) $75 — 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) €853 €851 Non-derivatives designated as net investment hedges: Foreign Currency Net Investment Hedges (in millions) EUR/USD (in EUR) €1,244 €1,243 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 tests a subset of its valuations against valuations received from transaction counterparties to validate the accuracy of its standard pricing models. The Company had no derivatives classified as Level 3 as of September 30, 2020 and December 31, 2019. 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 third quarter and first nine months 2020 or 2019. 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 within 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 within the Unaudited Consolidated Statements of Financial Position as of September 30, 2020 and December 31, 2019.

The designated foreign currency-denominated borrowings are included as part of "Long-term borrowings" within the Unaudited Consolidated Statements of Financial Position. For additional fair value measurement information, see Note 1, "Significant Accounting Policies", and Note 9, "Derivative and Non-Derivative Financial Instruments", to the consolidated financial statements in Part II, Item 8 of the Company's 2019 Annual Report on Form 10-K .

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" of the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. As a result of these derivatives, the Company recognized a net loss of $4 million and a net gain of $5 million during third quarter 2020 and 2019, respectively, and recognized a net gain of $4 million and $1 million during first nine months 2020 and 2019, respectively. 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 losses of $117 million and $50 million at September 30, 2020 and December 31, 2019, respectively. Losses recognized between September 30, 2020 and December 31, 2019 primarily resulted from an increase in foreign currency exchange rates associated with the euro, partially offset by commodity price increases. If recognized, approximately $18 million in pre-tax losses, as of September 30, 2020, would be reclassified into earnings during the next 12 months.

Commitments and Contingencies Disclosure [Abstract]
Commitments Disclosure [Text Block]	LEASES AND OTHER COMMITMENTS Leases There are two types of leases: finance and operating. Both types of leases have associated right-to-use assets and lease liabilities that are valued at the present value of the lease payments and recognized on the Unaudited Consolidated Statements of Financial Position. The discount rate used in the measurement of a right-to-use asset and lease liability is the rate implicit in the lease whenever that rate is readily determinable. If the rate implicit in the lease is not readily determinable, the collateralized incremental borrowing rate is used. The Company elected the accounting policy not to apply the recognition and measurement requirements to short-term leases with a term of 12 months or less and do not include a bargain purchase option. The Company has operating leases, as a lessee, with customary terms that do not include: significant variable lease payments; significant reasonably certain extensions or options required to be included in the lease term; restrictions; or other covenants for real property, rolling stock, and machinery and equipment. Real property leases primarily consist of office space and rolling stock leases primarily for railcars and fleet vehicles. At September 30, 2020 and December 31, 2019, operating right-to-use assets of $174 million and $197 million, respectively, are included as a part of "Other noncurrent assets" in the Unaudited Consolidated Statements of Financial Position and includes $8 million at both periods of assets previously classified as lease intangibles. Operating lease liabilities are included as a part of "Payables and other current liabilities" and "Other long-term liabilities" in the Unaudited Consolidated Statements of Financial Position. As of September 30, 2020, reconciliation of lease payments and operating lease liabilities is provided below: (Dollars in millions) Operating lease liabilities Remainder of 2020 $ 17 2021 56 2022 42 2023 29 2024 16 2025 and beyond 35 Total lease payments 195 Less: amounts of lease payments representing interest 18 Present value of future lease payments 177 Less: current obligations under leases 54 Long-term lease obligations $ 123 The Company has operating leases, primarily leases for railcars, with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease that will expire beginning in first quarter 2021. Residual guarantee payments that become probable and estimable are recognized as rent expense over the remaining life of the applicable lease. Management's current expectation is that the likelihood of material residual guarantee payments is remote. Lease costs during the period and other information is provided below: Third Quarter First Nine Months (Dollars in millions) 2020 2019 2020 2019 Lease costs: Operating lease costs $ 18 $ 17 $ 55 $ 49 Short-term lease costs 9 10 28 30 Sublease income (1) — (3) (1) Total $ 26 $ 27 $ 80 $ 78 Other operating lease information: Cash paid for amounts included in the measurement of lease liabilities $ 17 $ 17 $ 53 $ 52 Right-to-use assets obtained in exchange for new lease liabilities $ 10 $ 15 $ 40 $ 36 Weighted-average remaining lease term, in years 5 5 Weighted-average discount rate 3.8 % 4.1 % Debt and Other Commitments Eastman's obligations are summarized in the following table.

The Company had various purchase obligations at September 30, 2020, totaling approximately $2.5 billion over a period of approximately 30 years for materials, supplies, and energy incident to the ordinary conduct of business. Amounts in other liabilities represent the current estimated cash payments required to be made by the Company primarily for pension and other postretirement benefits, environmental matters, accrued compensation benefits, uncertain tax liabilities, and commodity and foreign exchange hedging in the periods indicated. Due to uncertainties in the timing of the effective settlement of tax positions with respect to taxing authorities, management is unable to determine the timing of payments related to uncertain tax liabilities and these amounts are included in the "2025 and beyond" line item. The amount and timing of pension and other postretirement benefit payments included in other liabilities is dependent upon interest rates, health care cost trends, actual returns on plan assets, retirement and attrition rates of employees, continuation or modification of the benefit plans, and other factors. Such factors can significantly impact the amount and timing of any future contributions by the Company. Excess contributions are periodically made by management in order to keep the plans' funded status above 80 percent under the funding provisions of the Pension Protection Act to avoid partial benefit restrictions on accelerated forms of payment. The Company's U.S. defined benefit pension plans are not currently under any benefit restrictions. See Note 7, "Retirement Plans". The resolution of uncertainties related to environmental matters included in other liabilities 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, if applicable, the expected sharing of costs, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will be material to the Company's consolidated financial position, results or operations, or cash flows.

ENVIRONMENTAL MATTERS AND ASSET

ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS	9 Months Ended

Accrual for Environmental Loss Contingencies Disclosure [Abstract]
Environmental Matters	ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS Certain Eastman manufacturing facilities generate hazardous and nonhazardous wastes, the treatment, storage, transportation, and disposal of which 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 2019 Annual Report on Form 10-K . The resolution of uncertainties related to environmental matters included in other liabilities 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, if applicable, the expected sharing of costs, management does not believe that the Company's liability for these environmental matters, individually or in the aggregate, will be material to the Company's consolidated financial position, results or operations, or cash flows. The Company's total reserve for environmental loss contingencies was $287 million at both September 30, 2020 and December 31, 2019. Environmental Remediation and Environmental Asset Retirement Obligations The Company's total environmental reserve that management believes to be probable and reasonably estimable for environmental contingencies, including remediation costs and asset retirement obligations, is included as part of "Payables and other current liabilities" and "Other long-term liabilities" in the Unaudited Consolidated Statements of Financial Position as follows: (Dollars in millions) September 30, 2020 December 31, 2019 Environmental contingent liabilities, current $ 15 $ 20 Environmental contingent liabilities, long-term 272 267 Total $ 287 $ 287 Environmental Remediation Estimated future environmental expenditures for undiscounted remediation costs ranged from the best estimate or minimum of $260 million to the maximum of $504 million at September 30, 2020 and from the best estimate or minimum of $260 million to the maximum of $487 million at December 31, 2019. The best estimate or minimum estimated future environmental expenditures are considered to be probable and reasonably estimable and include the amounts recognized at both September 30, 2020 and December 31, 2019. 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 included within "Cost of sales" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. Changes in the reserves for environmental remediation liabilities during first nine months 2020 and full year 2019 are summarized below: (Dollars in millions) Environmental Remediation Liabilities Balance at December 31, 2018 $ 271 Changes in estimates recognized in earnings and other 4 Cash reductions (15) Balance at December 31, 2019 260 Changes in estimates recognized in earnings and other 9 Cash reductions (9) Balance at September 30, 2020 $ 260 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. The Company recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The asset retirement obligations are discounted to expected present value and subsequently adjusted for changes in fair value. The associated estimated asset retirement costs are capitalized as part of the carrying value of the long-lived assets and depreciated over their useful life. Environmental asset retirement obligations consist primarily 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 was $27 million at both September 30, 2020 and December 31, 2019. 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 at Pace, Florida and Oulu, Finland. These recognized non-environmental asset retirement obligations were $50 million and $48 million at September 30, 2020 and December 31, 2019, respectively, and is included as part of "Other long-term liabilities" in the Unaudited Consolidated Statements of Financial Position.

Basis of Presentation [Abstract]
Basis of Accounting, Policy [Policy Text Block]	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 2019 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 the items noted below. The December 31, 2019 financial position data included herein was derived from the consolidated financial statements included in the 2019 Annual Report on Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States ("GAAP").
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards Accounting Standards Update ("ASU") 2016-13 Financial Instruments - Credit Losses: On January 1, 2020, Eastman adopted this standard, and related releases, under the various required transition methods. The amendments require a financial asset (including trade receivables) to be presented at the net amount expected to be collected through the use of allowances for credit losses valuation account. The income statement will reflect the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The adoption of this standard did not result in a material impact on the Company's financial statements and related disclosures. ASU 2018-13 Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement: On January 1, 2020, Eastman adopted this standard that is a part of the Financial Accounting Standards Board's ("FASB") disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary changes applicable to Eastman in this update are the disclosures of fair value levels, assessment thereof, and transfers between those levels. The adoption under the various required transition methods did not impact the Company's related disclosures. ASU 2018-18 Collaborative Arrangements - Clarifying the Interaction between Topic 808 (Collaborative Arrangements) and Topic 606 (Revenue from Contracts with Customers): On January 1, 2020, Eastman adopted this standard, retrospectively to the date of the initial application of Topic 606 on January 1, 2017, that provides clarification in regards to which contracts are accounted for under Topic 808 and Topic 606 as well as alignment of guidance between the two pronouncements. The adoption of this standard did not impact the Company's financial statements and related disclosures. ASU 2019-01 Leases - Codification Improvements: On January 1, 2020, Eastman adopted this standard which was applied as of the adoption date and under the same transition methodology of ASU 2016-02 Lease previously adopted on January 1, 2019. The FASB issued this update in response to stakeholder inquiries regarding the new leasing standard. The adoption of this standard did not impact the Company's financial statements and related disclosures. ASU 2020-04 Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting : Eastman adopted this standard when issued and effective on March 12, 2020. The FASB issued this update to provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform (the global financial markets transition in contracts, hedging relationships, and other transactions away from referencing the London Interbank Offered Rate (LIBOR) and other interbank offered rates and toward new reference rates) on financial reporting. As reference reform has not impacted Eastman as of the issuance and effective date, the adoption of this standard did not impact the Company's financial statements and related disclosures. Accounting Standards Issued But Not Adopted as of September 30, 2020 ASU 2018-14 Retirement Benefits - Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans: In August 2018, the FASB issued this update as a part of its disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements. The primary change impacting Eastman is the addition of disclosures related to significant gains and losses related to changes in the benefit obligation for the period and weighted-average interest crediting rates for cash balance plans. This standard is effective for fiscal years ending after December 15, 2020. Upon adoption, this update is to be applied on a retrospective basis to all periods presented. Management does not expect that changes required by the new standard will materially impact the Company's related disclosures. ASU 2019-12 Income Taxes - Simplifying the Accounting for Income Taxes : In December 2019, the FASB issued this update as part of its initiative to reduce complexity in accounting standards which removes certain exceptions and provides simplification to specific tax items. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Adoption methods vary based on the specific items impacted. Management is currently evaluating the impact on the Company's financial statements and related disclosures.
Off-Balance-Sheet Credit Exposure, Policy	Working Capital Management and Off Balance Sheet Arrangements Since 2019, the Company has been expanding its 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 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 in third quarter 2020 and 2019 were $336 million and $190 million, respectively, and $1.20 billion and $460 million in first nine months 2020 and 2019, respectively. The Company works with suppliers to optimize payment terms and conditions on accounts payable to enhance timing of working capital and cash flows. As part of these efforts, in 2019 the Company introduced a voluntary supply chain finance program to provide suppliers with the opportunity to 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. All of Eastman's accounts payable and associated payments are reported consistently in the Company's Unaudited Consolidated Statements of Financial Position and Unaudited Consolidated Statements of Cash Flows regardless of whether they are associated with a vendor who participates in the program.

[6]	Fixed asset impairments and severance in the AFP segment from the closure of an animal nutrition manufacturing facility in Asia Pacific as part of ongoing site optimization.
[7]	Severance charges of $1 million and $4 million in third quarter and first nine months 2020, respectively, in the Chemical Intermediates ("CI") segment, and $1 million in both third quarter and first nine months 2020 in the AFP segment, resulting from the previously disclosed plan to discontinue production of certain products at the Singapore manufacturing site. Restructuring charges totaling up to $50 million are expected through 2020 and 2021 for this action.
[8]	Fixed asset impairments and contract termination fees resulting from management's decision to discontinue growth initiatives for polyester based microfibers, including Avra ™ performance fibers, the financial results of which were not allocated to an operating segment and reported in "Other".

[10]	Severance in the AM segment due to the closure of an advanced interlayers manufacturing facility in North America as part of ongoing site optimization. In addition, accelerated depreciation of $7 million was recognized in "Cost of sales" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings in third quarter 2020 related to the closure of this facility. Management expects total charges of up to $30 million, mostly in "Cost of sales" and in "Asset impairments and restructuring charges, net" in the Unaudited Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings, in 2020 and 2021 for the closure of this facility.
