	The accompanying unaudited consolidated financial statements have been prepared by Eastman Chemical Company (the "Company" or "Eastman") in accordance and consistent with the accounting policies stated in the Company's 2014 Annual Report on Form 10-K and should be read in conjunction with the consolidated financial statements in Part II, Item 8 of the Company's 2014 Annual Report on Form 10-K. The December 31, 2014 financial position data included herein was derived from the audited consolidated financial statements included in the 2014 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States ("GAAP"). The unaudited consolidated financial statements are prepared in conformity with GAAP and of necessity include 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.
	Off Balance Sheet Financing Arrangements
	The Company assumed the rights and obligations under non-recourse factoring facilities as part of the acquisition of Taminco Corporation ("Taminco"). The non-recourse factoring facilities have a combined limit of $170 million (the U.S. Dollar equivalent of the €158 million commitment amount as of March 31, 2015) and are committed until December 2017. These arrangements include receivables in the United States, Belgium, Germany, and Finland, and are subject to various eligibility requirements. The Company sells the receivables at face value but receives funding (approximately 85 percent) net of a deposit amount until collections are received from customers for the receivables sold. The total amount of cumulative receivables sold in first quarter 2015 was $269 million. The total amount of cumulative receivables sold during the year ended December 31, 2014 since the acquisition of Taminco on December 5, 2014 was $70 million. As part of the program, the Company continues to service the sold receivables at market rates with no servicing assets or liabilities recognized. The amounts of sold receivables outstanding under the non-recourse factoring facilities were $118 million and $105 million at March 31, 2015 and December 31, 2014, respectively. The fair value of the receivables sold equals the carrying value at the time of the sale, and no gain or loss is recorded. The Company is exposed to a credit loss of up to 10 percent on sold receivables.

	Credit Facility and Commercial Paper Borrowings
	In connection with the acquisition of Taminco, Eastman entered into a $1.0 billion five-year Term Loan Agreement. As of March 31, 2015, the Term Loan Agreement balance outstanding was $1.0 billion with an interest rate of 1.43 percent. As of December 31, 2014, the Term Loan Agreement balance outstanding was $1.0 billion with an interest rate of 1.41 percent. Borrowings under the Term Loan Agreement are subject to interest at varying spreads above quoted market rates.
	The Company has access to a $1.25 billion revolving credit agreement (the "Credit Facility") expiring October 2019. 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. At March 31, 2015 and December 31, 2014, the Company had no outstanding borrowings under the Credit Facility.
	The Credit Facility provides liquidity support for commercial paper borrowings and general corporate purposes. Accordingly, any outstanding commercial paper borrowings reduce capacity for borrowings available under the Credit Facility. Given the expiration date of the Credit Facility, any commercial paper borrowings supported by the Credit Facility are classified as long-term borrowings because the Company has the ability and intent to refinance such borrowings on a long-term basis. At March 31, 2015 the Company's commercial paper borrowings were $328 million with a weighted average interest rate of 0.56 percent. At December 31, 2014 the Company's commercial paper borrowings were $235 million with a weighted average interest rate of 0.47 percent.
	The Company also has a $250 million line of credit under its accounts receivable securitization agreement (the "A/R Facility"), expiring April 2017. Borrowings under the A/R Facility are subject to interest rates based on a spread over the lender's borrowing costs, and the Company pays a fee to maintain availability of the A/R Facility. At March 31, 2015 and December 31, 2014 the Company had no outstanding borrowings under the A/R Facility. During first quarter 2014, $125 million of the available amount under the A/R Facility was borrowed and then repaid during second quarter 2014.
	The Term Loan Agreement, Credit Facility, and the A/R Facility contain a number of customary covenants and events of default, including the maintenance of certain financial ratios. The Company was in compliance with all such covenants for all periods presented. Total available borrowings under the Credit Facility and A/R Facility were $1,172 million and $1,265 million as of March 31, 2015 and December 31, 2014, respectively. The Company would not violate applicable covenants for these periods if the total available amounts of the facilities had been borrowed.
	Fair Value of Borrowings
	The Company has classified its long-term borrowings at March 31, 2015 and December 31, 2014 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 2014 Annual Report on Form 10-K. The fair value for fixed-rate debt securities is based on current market prices and is classified as Level 1. The fair value for the Company's other borrowings, which include the Term Loan Agreement, A/R Facility, commercial paper, and capital leases equals the carrying value and is classified as Level 2.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES
	Hedging Programs
	The Company is exposed to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates. To mitigate these market risk factors and their effects on the cash flows of the underlying transaction, the Company uses various 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 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 Company does not enter into derivative transactions for speculative purposes.
	For further information on hedging programs, see Note 10, "Derivatives", to the consolidated financial statements in Part II, Item 8 of the Company's 2014 Annual Report on Form 10-K.
	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. For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings. In 2014, the Company entered into interest rate swaps to hedge the interest rate risk on the 3.6% notes due 2022. As of March 31, 2015 and December 31, 2014, the total notional amount of the Company's interest rate swaps was $275 million.

	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 is attributable to a particular risk. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income, net of income taxes and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivatives representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

	Hedging Summary
	Monetized positions and mark-to-market gains and losses from raw materials and energy, currency, and certain interest rate hedges that were included in accumulated other comprehensive income before taxes totaled losses of $348 million at March 31, 2015 and $66 million at March 31, 2014. Losses increased in 2015 compared to 2014 as a result of a sharp decline in commodity prices, particularly propane, partially offset by increased gains resulting from a weaker Euro and Japanese Yen. If realized, $107 million net losses as of March 31, 2015 will be reclassified into earnings during the next 12 months. Ineffective portions of hedges are immediately recognized in cost of sales or other charges (income), net.
	The gains or losses on nonqualifying derivatives or derivatives that are not designated as hedges are marked to market and reported in the line item "Other (income) charges, net" of the Unaudited Consolidated Statements of Earnings, and, in all periods presented, represent foreign exchange derivatives denominated in multiple currencies and are transacted and settled in the same quarter. The Company recognized $11 million net losses during first quarter 2015 on nonqualifying derivatives. There were no net losses or gains during first quarter 2014.

The majority of the Company's derivative assets are classified as Level 2. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs which 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 the transaction's counterparty to validate the accuracy of its standard pricing models. Counterparties to these derivative contracts are highly rated financial institutions which the Company believes carry minimal risk of nonperformance.
All of 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 has elected to present the derivative contracts on a gross basis in the Unaudited Consolidated Statements of Financial Position. Had it chosen to present the derivatives contracts on a net basis, it would have a derivative in a net asset position of $222 million and a derivative in a net liability position of $466 million as of March 31, 2015. The Company does not have any cash collateral due under such agreements.

COMMITMENTS	COMMITMENTS
	Purchase Obligations and Lease Commitments
	The Company had various purchase obligations at March 31, 2015 totaling $2.0 billion over a period of approximately 30 years for materials, supplies, and energy incident to the ordinary conduct of business. The Company also had various lease commitments for property and equipment under cancelable, noncancelable, and month-to-month operating leases totaling $285 million over a period of approximately 45 years. Of the total lease commitments, approximately 50 percent relate to real property, including office space, storage facilities, and land; approximately 40 percent relate to railcars; and approximately 10 percent relate to machinery and equipment, including computer and communications equipment and production equipment.
	Guarantees
	The Company has operating leases with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease as well as other guarantees. Disclosures about each group of similar guarantees are provided below.
	Residual Value Guarantees
	The Company has operating leases with terms that require the Company to guarantee a portion of the residual value of the leased assets upon termination of the lease. These residual value guarantees at March 31, 2015 totaled $121 million and consisted primarily of leases for railcars and company aircraft and will expire beginning in 2016. Management's current expectation is that the likelihood of material residual guarantee payments is remote.
	Other Guarantees
	Guarantees and claims also arise during the ordinary course of business from relationships with customers, suppliers, joint venture partners, and other parties when the Company undertakes an obligation to guarantee the performance of others, if specified triggering events occur. Non-performance under a contract could trigger an obligation of the Company. The Company's current other guarantees include guarantees relating primarily to intellectual property, environmental matters, and other indemnifications and have arisen through the normal course of business. The ultimate effect on future financial results is not subject to reasonable estimation because considerable uncertainty exists as to the final outcome of these claims, if they were to occur. These other guarantees have terms up to 30 years with maximum potential future payments of $29 million in the aggregate, with none of these guarantees being individually significant to the Company's operating results, financial position, or liquidity. Management's current expectation is that future payment or performance related to non-performance under other guarantees is remote.

Accrual for Environmental Loss Contingencies Disclosure [Abstract]
Environmental Matters	ENVIRONMENTAL MATTERS AND ASSET RETIREMENT OBLIGATIONS
	Certain Eastman manufacturing sites 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 such cleanup costs. In addition, the Company will be required to incur costs for environmental remediation and closure and postclosure 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 2014 Annual Report on Form 10-K. The Company's total reserve for environmental contingencies was $340 million and $345 million at March 31, 2015 and December 31, 2014, respectively. At March 31, 2015 and December 31, 2014, this reserve included $8 million and $10 million, respectively, related to sites previously closed and impaired by Eastman and sites that have been divested by Eastman but for which the Company retains the environmental liability related to these sites.
	Estimated future environmental expenditures for remediation costs ranged from the minimum or best estimate of $317 million to the maximum of $544 million and from the minimum or best estimate of $324 million to the maximum of $548 million at March 31, 2015 and December 31, 2014, respectively. The maximum estimated future costs are considered to be reasonably possible and include the amounts accrued at both March 31, 2015 and December 31, 2014. Although the resolution of uncertainties related to these environmental matters may have a material adverse effect on the Company's consolidated results of operations in the period recognized, 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 or cash flows.
	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 obligation is 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 of primarily closure and post-closure costs. For facilities that have environmental asset retirement obligations, the best estimate accrued to date over the facilities' estimated useful lives for these environmental asset retirement obligation costs was $23 million and $21 million at March 31, 2015 and December 31, 2014, respectively.
	Reserves for environmental remediation that management believe to be probable and estimable are recorded as current and long-term liabilities in the Unaudited Consolidated Statements of Financial Position. These reserves include liabilities expected to be paid out within 30 years. The amounts charged to pre-tax earnings for environmental remediation and related charges are included in cost of sales and other charges (income), net, and are summarized below:
	(Dollars in millions)	Environmental Remediation Liabilities
	Balance at December 31, 2014	$	324
	Changes in estimates recorded to earnings	2
	Cash reductions	(9		)
	Balance at March 31, 2015	$	317
	The Company's total environmental reserve for environmental contingencies, including remediation costs and asset retirement obligations, is recorded in the Unaudited Consolidated Statements of Financial Position as follows:
	(Dollars in millions)	March 31, 2015			December 31, 2014
	Environmental contingent liabilities, current	$	35		$	35
	Environmental contingent liabilities, long-term	305			310
	Total	$	340		$	345
	The Company also 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 acquired from Taminco. These accrued non-environmental asset retirement obligations were $44 million as of both March 31, 2015 and December 31, 2014.

	In first quarter 2015, there were net asset impairments and restructuring charges of $109 million. Net asset impairment and restructuring charges included $81 million of asset impairments and $16 million of restructuring charges, including severance, in the Fibers segment due to the closure of the Workington, UK acetate tow manufacturing facility. Additionally, in first quarter 2015, management decided not to continue a growth initiative that was reported in "Other". This resulted in the Company recognizing asset impairments of $8 million and restructuring charges of $4 million.
	In first quarter 2014, there were $13 million of net asset impairments and restructuring charges. Net asset impairments and restructuring charges consisted of $8 million of asset impairments and $2 million of restructuring charges in the Advanced Materials ("AM") segment primarily due to the closure of a production facility in Taiwan for the Flexvue® performance films product line and $3 million of restructuring charges for severance associated with the integration of Solutia.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
SHARE-BASED COMPENSATION AWARDS	SHARE-BASED COMPENSATION AWARDS
	The Company utilizes share-based awards under employee and non-employee director compensation programs. These share-based awards may include restricted and unrestricted stock, restricted stock units, stock options, and performance shares. In first quarter 2015 and 2014, $11 million and $9 million, respectively, of compensation expense before tax were recognized in selling, general and administrative expense in the Unaudited Consolidated Statements of Earnings for all share-based awards of which $3 million and $2 million, respectively, related to 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 forms of award notice. For first quarter 2015 and 2014, approximately $2 million and $1 million, respectively, of stock option compensation expense was recognized due to qualifying termination eligibility preceding the requisite vesting period. The impact on first quarter 2015 and 2014 net earnings of $7 million and $5 million, respectively, is net of deferred tax expense related to share-based award compensation for each period.
	Stock Option Grants
	In first quarter 2015 and 2014, the number of stock options granted under the 2012 Omnibus Stock Compensation Plan were approximately 500,000 and 200,000, 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 2015 and 2014 are provided in the table below:
		First Quarter
	Assumptions	2015	2014
	Expected volatility rate	24.11%	26.30%
	Expected dividend yield	1.75%	1.70%
	Average risk-free interest rate	1.45%	1.39%
	Expected forfeiture rate	0.75%	0.75%
	Expected term years	4.8	4.7
	The grant date exercise price and fair value of options granted during first quarter 2015 were $74.46 and $13.89, respectively, and during first quarter 2014 were $87.43 and $17.67, respectively.
	For options unvested at March 31, 2015, approximately $7 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 share awards, restricted stock and restricted stock unit awards, 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. 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 2015 and 2014 for the 2015-2017 and 2014-2016 periods were approximately 300,000 for each period. The target shares awarded are assumed to be 100 percent. At the end of the three-year performance period, the actual number of shares awarded can range from zero percent to 250 percent of the target shares based on the award notice. The number of restricted stock unit awards during first quarter 2015 and 2014 were approximately 200,000 and 100,000, 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 2015 and 2014, $8 million and $7 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, 2015 was approximately $64 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 2014 Annual Report on Form 10-K.

RECENTLY_ISSUED_ACCOUNTING_STA

RECENTLY ISSUED ACCOUNTING STANDARDS	3 Months Ended

Recently Issued Accounting Standards [Abstract]
Recently Issued Accounting Standards [Text Block]	RECENTLY ISSUED ACCOUNTING STANDARDS
	In May 2014, the Financial Accounting Standards Board ("FASB") and International Accounting Standards Board jointly issued new principles-based accounting guidance for revenue recognition that will supersede virtually all existing revenue guidance. The core principle of this guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. To achieve the core principle, the guidance establishes the following five steps: 1) identify the contract(s) with a customer, 2) identify the performance obligation in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also details the accounting treatment for costs to obtain or fulfill a contract. Lastly, disclosure requirements have been enhanced to provide sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is currently evaluating the impact on the Company's financial position or results of operations and related disclosures.
	In April 2015, the FASB issued new guidance for debt issuance costs as a part of the simplification and productivity initiative. Under this guidance debt issuance costs will be presented as a direct reduction from the carrying amount of the debt liability, consistent with the presentation of debt discounts. The amortization of debt issuance costs will be reported as interest expense. The recognition and measurement guidance for debt issuance costs is not affected by the amendment. The new guidance is to be applied on a retrospective basis and reported as a change in an accounting principle. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted for financial statements that have not been previously issued. The Company is currently evaluating changes in its accounting required by this new guidance and the impact to the Company's financial position, results of operations and related disclosures.
	In April 2015, the FASB issued new guidance for cloud computing arrangement fees, also as a part of the simplification and productivity initiative. The guidance establishes a new requirement to determine if cloud computing arrangements includes a software license. If an arrangement is deemed to include a software license then the customer would account for the license as any other purchased software, capitalized and depreciated over the life of the contract. If an arrangement is deemed not to include a license, the agreement would be accounted for as a service contract. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period and early adoption is permitted. The Company is currently evaluating changes in its accounting required by this new guidance and the impact to the Company's financial position, results of operations and related disclosures.

Hedging Programs [Abstract]

Objectives for Using Derivative Instruments

The Company is exposed to market risks, such as changes in foreign currency exchange rates, commodity prices, and interest rates.B To mitigate these market risk factors and their effects on the cash flows of the underlying transaction, the Company uses various derivative financial instruments when appropriate in accordance with the Company's hedging strategy and policies.B Designation is performed on a specific exposure basis to support hedge accounting.B 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.B The Company does not enter into derivative transactions for speculative purposes.
