Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES
	Financial Statement Presentation
	The consolidated financial statements of Eastman and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments.  Future actual results could differ from such current estimates.  The 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 in minority-owned companies 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 Consolidated Financial Statements and accompanying footnotes to conform to current period presentation.
	Information related to the Commonwealth Laminating and Coating, Inc., ("Commonwealth") acquisition completed on December 11, 2014, the Taminco Corporation ("Taminco") acquisition completed on December 5, 2014, the Knowlton Technologies, LLC ("Knowlton") acquisition completed on August 6, 2014, the BP plc Global Aviation Turbine Engine Oil Business ("aviation turbine oil business") acquisition completed on June 2, 2014, and the Solutia, Inc. ("Solutia") acquisition completed on July 2, 2012 is in Note 2, "Acquisitions".  As of the date of acquisition, results of the acquired businesses are included in Eastman results.
	Cash and Cash Equivalents
	Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less.
	Fair Value Measurements
	The Company records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  These fair value principles prioritize valuation inputs across three broad levels.  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.  Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.  Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value.  An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments.  The allowances are based on the number of days an individual receivable is delinquent and management's regular assessment of the financial condition of the Company's customers.  The Company considers a receivable delinquent if it is unpaid after the terms of the related invoice have expired.  The Company evaluates the allowance based on a monthly assessment of the aged receivables.  Write-offs are recorded at the time a customer receivable is deemed uncollectible.  Allowance for doubtful accounts was $10 million and $12 million at December 31, 2014 and 2013, respectively.  The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business.
	The Company assumed the rights and obligations under non-recourse factoring facilities as part of the acquisition of Taminco. The non-recourse factoring facilities have a combined limit of $192 million (the U.S. Dollar equivalent of the €158 million commitment amount as of December 31, 2014) 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 eligible receivables sold and derecognized since the acquisition of Taminco on December 5, 2014 through December 31, 2014 was $61 million. The amounts outstanding under the non-recourse factoring facilities were $105 million at December 31, 2014. As part of the program, the Company continues to service the receivables at market rates with no servicing assets or liabilities recorded. 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 up to 5 percent on sold receivables.
	Inventories
	Inventories are valued at the lower of cost or market.  The Company determines the cost of most raw materials, work in process, and finished goods inventories in the United States by the last-in, first-out ("LIFO") method.  The cost of all other inventories, including inventories outside the United States, is determined by the average cost method, which approximates the first-in, first-out ("FIFO") method.  The Company writes-down its inventories for estimated obsolescence or unmarketable inventory equal to the difference between the carrying value of inventory and the estimated market value based upon assumptions about future demand and market conditions.
	Properties
	The Company records properties at cost.  Maintenance and repairs are charged to earnings; replacements and betterments are capitalized.  When Eastman retires or otherwise disposes of assets, it removes the cost of such assets and related accumulated depreciation from the accounts.  The Company records any profit or loss on retirement or other disposition into earnings.  Asset impairments are reflected as increases in accumulated depreciation for properties that have been placed in service.  In instances when an asset has not been placed in service and is impaired, the associated costs are removed from the appropriate property accounts.
	Depreciation and Amortization
	Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method.  Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in Cost of Sales.
	Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset.
	For additional information, see Note 5, "Goodwill and Other Intangible Assets".
	Computer Software Costs
	Capitalized software costs are amortized primarily on a straight-line basis over three years, the expected useful life of such assets, beginning when the software project is substantially complete and placed in service.  Capitalized software in 2014, 2013, and 2012 was approximately $3 million, $5 million, and $5 million, respectively, and consisted of costs to internally develop computer software used by the Company.  During each of those same periods, approximately $7 million of previously capitalized costs were amortized.  At December 31, 2014 and 2013, unamortized capitalized software costs were $11 million and $14 million, respectively.  Capitalized software costs are reflected in other noncurrent assets.
	Impairment of Long-Lived Assets
	Definite-lived Assets
	Properties and equipment and definite-lived intangible assets to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  The review of these long-lived assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered.  An impairment is recorded for the excess of the carrying amount of the asset over the fair value. Fair value is either salvage value determined through market analysis or alternative future use.
	As the Company's assumptions related to long-lived assets are subject to change, write-downs may be required in the future. If estimates of fair value less costs to sell are revised, the carrying amount of the related asset is adjusted, resulting in a charge to earnings.
	Goodwill
	The Company conducts testing of goodwill annually in third quarter of each year or when impairment indicators arise, whichever comes first. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as one level below an operating segment, and in order to be a reporting unit, the component must 1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, member, or participants); 2) have discrete financial information available; and 3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. During 2014 testing, the Company did not evaluate the components acquired from Solutia in 2012 for aggregation, instead testing each component as a separate reporting unit. However, management will continue to review further aggregation during the next annual testing process as those components have now been integrated into Eastman.
	The Company uses an income approach and applies a fair value methodology based on discounted cash flows in testing the carrying value of goodwill for each reporting unit. The key assumptions and estimates used in the Company's 2014 goodwill impairment testing included a long-term projection of revenues, expenses, and cash flows, the estimated discount rate, and the estimated tax rate. The Company believes these assumptions are consistent with those a hypothetical market participant would use given circumstances that were present at the time the estimates were made. However, actual results and amounts may be significantly different from the Company's estimates. In addition, the use of different estimates or assumptions could result in materially different determinations. If the estimated fair value of a reporting unit is determined to be less than the carrying value of the net assets of the reporting unit including goodwill, additional steps, including an allocation of the estimated fair value to the assets and liabilities of the reporting unit, would be necessary to determine the amount, if any, of goodwill impairment.
	Indefinite-lived Intangible Assets
	The Company conducts testing of indefinite-lived intangible assets annually in third quarter of each year or when impairment indicators arise, whichever comes first. The carrying value of indefinite-lived intangible assets is considered to be impaired when the fair value, as established by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying values.
	Indefinite-lived intangible assets, consisting of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company uses an income approach, specifically the relief from royalty method, to test indefinite-lived intangible assets. The estimated fair value of the tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant weighted average cost of capital plus a one percent risk premium. The carrying value of indefinite-lived intangible assets is considered to be impaired when the estimated fair value is less than the carrying value of the trademarks.
	Investments
	The consolidated financial statements include the accounts of the Company and all its subsidiaries and entities/joint ventures in which a controlling interest is maintained.
	Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis.  Under the equity method of accounting, these investments are included in other noncurrent assets.  The Company includes its share of earnings and losses of such investments in other (income) charges, net, and its share of other comprehensive income (loss) in the appropriate component of accumulated other comprehensive income (loss) in stockholders' equity.
	Pension and Other Postretirement Benefits
	The Company maintains defined benefit pension plans that provide eligible employees with retirement benefits.  Additionally, Eastman provides a subsidy toward life insurance, health care, and dental benefits for eligible retirees and a subsidy toward health care and dental benefits for retirees' eligible survivors.  The costs and obligations related to these benefits reflect the Company's assumptions related to general economic conditions (particularly interest rates), expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends.  The cost of providing plan benefits depends on demographic assumptions including retirements, mortality, turnover, and plan participation.
	Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized as an MTM adjustment in the quarter in which such remeasurement event occurs.
	For additional information, see Note 11, "Retirement Plans".
	Environmental Costs
	The Company accrues environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated.  When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount.  This undiscounted accrued amount reflects liabilities expected to be paid out within 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties.  Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs.
	The Company also establishes reserves for closure/postclosure costs associated with the environmental and other assets it maintains.  Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments.  When these types of assets are constructed or installed, a reserve is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets and the applicable regulatory closure requirements.  These expenses are charged into earnings over the estimated useful life of the assets.  Currently, the Company estimates the useful life of each individual asset up to 50 years.  If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, the expenses charged into earnings could increase or decrease.  The Company also monitors conditional obligations and recognizes contingent liabilities associated with them when and to the extent that more detailed information becomes available concerning applicable retirement costs.
	The current portion of accruals for environmental liabilities is included in payables and other current liabilities with the long-term portion included in other long-term liabilities. These accruals exclude claims for recoveries from insurance companies or other third parties.  Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination.  The cost of operating and maintaining environmental control facilities is charged to expense.
	For additional information see Note 13, "Environmental Matters and Asset Retirement Obligations".
	Derivative Financial Instruments
	Derivative financial instruments are used by the Company when appropriate to manage its exposures to fluctuations in foreign currency exchange rates, certain contract sales prices, raw material and energy costs, and interest rates.  These instruments are used to mitigate the risk that changes in exchange rates, sales prices, raw material and energy costs, or interest rates will adversely affect the eventual dollar cash flows resulting from the hedged transactions.
	From time to time, the Company enters into currency option and forward contracts to hedge anticipated, but not yet committed, export sales and purchase transactions expected within no more than five years and denominated in foreign currencies (principally the euro and the Japanese yen); and forward exchange contracts to hedge certain firm commitments denominated in foreign currencies.  To mitigate fluctuations in the market prices of commodities and their effects on the cash costs of the underlying transactions expected over the next five years for propane, ethane, natural gas, paraxylene, and benzene (certain raw material and energy used in the manufacturing process) and selling prices for ethylene, the Company may enter into option and forward contracts.  From time to time, the Company also utilizes interest rate derivative instruments, primarily forward starting interest rate swaps and Treasury locks, to hedge the Company's exposure to movements in interest rates.
	The Company's qualifying option and forward contracts are accounted for as hedges because the derivative instruments are designated and demonstrated to be effective as hedges of the underlying risks.  Gains and losses resulting from effective hedges of existing liabilities, firm commitments, or anticipated transactions are deferred and recognized when the offsetting gains and losses are recognized on the related hedged items and are reported as a component of operating earnings.  Derivative assets and liabilities are recorded at fair value.
	The gains or losses on nonqualifying derivatives or derivatives that are not designated as hedges are marked to market and immediately recorded into earnings from continuing operations.
	Deferred option premiums are included in the fair market value of the hedges.  The related obligation for payment is generally included in other liabilities and is paid in the period in which the options are exercised or expire.
	For additional information see Note 10, "Derivatives".
	Litigation and Contingent Liabilities
	The Company and its operations from time to time are, and in the future may be, parties to or targets of lawsuits, claims, investigations, and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business.  The Company accrues a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated.  When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount.  The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred.
	Revenue Recognition and Customer Incentives
	The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the customer is fixed or determinable, and collectability is reasonably assured.  Revenue for products is recognized when title and risk of loss transfer to the customer.
	The Company records estimated obligations for customer programs and incentive offerings, which consist primarily of revenue or volume-based amounts that a customer must achieve over a specified period of time, as a reduction of revenue from each underlying revenue transaction as the customer progresses toward goals specified in incentive agreements.  These estimates are based on a combination of forecasts of customer sales and actual sales volume and revenues against established goals, the customer's current level of purchases, Eastman's knowledge of customer purchasing habits, and industry pricing practice.  The incentive payment rate may be variable, based upon the customer reaching higher sales volume or revenue levels over a specified period of time in order to receive an agreed upon incentive payment.
	Shipping and Handling Fees and Costs
	Shipping and handling fees related to sales transactions are billed to customers and are recorded as sales revenue.  Shipping and handling costs incurred are recorded in cost of sales.
	Restructuring of Operations
	The Company records restructuring charges incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months.  These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, obsolete inventory, or other costs directly related to the restructuring.  The Company records severance charges for employee separations when the separation is probable and reasonably estimable.  In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees.
	Share-based Compensation
	The Company recognizes compensation expense in the financial statements for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period.
	For additional information, see Note 18, "Share-Based Compensation Plans and Awards".
	Research and Development
	All costs identified as research and development ("R&D") costs are charged to expense when incurred with the exception of third-party reimbursed and government-funded R&D.  Expenses for third-party reimbursed and government-funded R&D are deferred until reimbursement is received to ensure appropriate matching of revenue and expense, provided specific criteria are met.
Income Taxes
The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes.  Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid.  The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year.  Deferred taxes result from differences between the financial and tax bases of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.  Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.  Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested.
The Company recognizes income tax positions that meet the more likely than not threshold and accrues interest related to unrecognized income tax positions which is recorded as a component of the income tax provision.
Accounting Standard ASU 2013-11, Income Taxes (Topic 740), effective for reporting periods beginning after December 15, 2013, requires unrecognized tax benefits to be offset against a deferred tax asset for a net operating loss carryforward or similar tax loss or tax credit carryforward.  As of December 31, 2014, the prospective adoption of this standard resulted in a reduction in noncurrent deferred income tax assets of $93 million in other noncurrent assets and a corresponding decrease in other long-term liabilities.
Purchase Accounting
In general, the acquisition method of accounting requires recognition of assets acquired and liabilities assumed at their respective fair values at the date of acquisition. For assets and liabilities other than intangible assets and property, plant, and equipment, the Company estimates fair value using the exit price approach which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly market. An exit price is determined from the viewpoint of unrelated market participants as a whole, in the principal or most advantageous market, and may result in the Company valuing assets or liabilities at a fair value that is not reflective of the Company's intended use of the assets or liabilities. Any amount of the purchase price paid that is in excess of the estimated fair values of net assets acquired or liabilities assumed is recorded in the line item goodwill on the Company's consolidated balance sheets.
For intangible assets, the Company uses the income, market, or cost approach (or a combination thereof) for the valuation as appropriate, and uses valuation inputs in these models and analyses that are based on market participant assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data which includes consideration of obsolescence. See Note 2, "Acquisitions". Management's judgment is used to determine the estimated fair values assigned to assets acquired and liabilities assumed, as well as asset lives for property, plant and equipment and amortization periods for intangible assets, and can materially affect the Company's results of operations.

ACQUISITIONS	ACQUISITIONS
	Taminco Corporation
	On December 5, 2014, the Company completed its acquisition of the Taminco Corporation ("Taminco"), a global specialty chemical company.  In the acquisition, each outstanding share of Taminco common stock was cancelled and converted automatically into the right to receive $26.00 in cash, ("Acquisition Consideration"). Additionally, each outstanding option to acquire shares of Taminco common stock issued under any of Taminco's equity incentive plans, whether or not then vested, was converted into the right to receive, in cash and for each share of Taminco common stock subject to such option, the amount by which the value of the Acquisition Consideration exceeded such option's exercise price. The fair value of total consideration transferred was $2.8 billion, consisting of cash of $1.7 billion, net of cash acquired, and repayment of Taminco's debt of $1.1 billion. The acquisition was accounted for as a business combination. Taminco's former specialty amines and crop protection businesses are now operated as part of the Additives & Functional Products ("AFP") segment and its former functional amines business are now operated as part of the Specialty Fluids & Intermediates ("SFI") segment. The businesses acquired from Taminco are expected to provide additional opportunities for growth to Eastman in agriculture, personal care, coatings, and oil and gas markets.
	The funding of the cash portion of the purchase price, repayment of Taminco's debt, and acquisition costs were provided primarily from borrowings, including the $1.96 billion net proceeds from the public offering of notes on November 20, 2014 and borrowings of $1.0 billion on December 5, 2015 under a five-year term loan agreement (the "Term Loan Agreement").  See Note 9, "Borrowings".
	The following table summarizes the preliminary purchase price allocation for the Taminco acquisition, any subsequent adjustments are not expected to have a material impact on the Company's results of operations:
	Assets acquired and liabilities assumed
	(Dollars in millions)	As of December 5, 2014
	Current assets	$	266
	Properties and equipment	658
	Intangible assets	1,002
	Other noncurrent assets	37
	Goodwill	1,509
	Current liabilities	(161		)
	Long-term liabilities	(546		)
	Total purchase price, net of cash acquired	$	2,765
	The Company used the income, market, or cost approach (or a combination thereof) for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions.  Market participants are considered to be buyers and sellers unrelated to Eastman in the principal or most advantageous market for the asset or liability. For certain items, the carrying value was determined to be a reasonable approximation of fair value based on information available to Eastman management. Current assets consist primarily of inventory, cash, and trade receivables. The fair value and gross contractual amounts trade receivables acquired from Taminco on December 5, 2014 was $94 million. Properties acquired included a number of manufacturing, sales, and distribution sites and related facilities, land and leased sites that include leasehold improvements, and machinery and equipment for use in manufacturing operations.  Management valued properties using the cost approach supported where available by observable market data which includes consideration of obsolescence.
	Acquired intangible assets are definite-lived assets and consist primarily of customer relationships, developed technologies, and contracts. Customer relationships acquired are in industries such as agriculture and personal care. The Company has preliminarily concluded that it has a favorable methanol supply contract. In addition, assets acquired include technologies related to many products protected by a number of existing patents and trade secrets. Management valued customer relationships using the excess from earnings method, contracts using the Black Scholes model, and developed technology using the relief from royalty method. All valuation methods are forms of the income approach supported by observable market data for peer chemical companies.
	Intangible Assets acquired
	(Dollars in millions)	Fair Value			Weighted-Average Amortization Period (Years)
	Amortizable intangible assets
	Customer relationships	$	601		24
	Developed technologies	205			17
	Contracts	180			5
	Other intangible assets	16			10
	Total	$	1,002
	Other noncurrent assets consist primarily of deferred tax assets and investments. In connection with the acquisition, the Company recorded goodwill, which represents the excess of the purchase price over the estimated preliminary fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to Taminco as a going concern and the fair value of expected cost synergies and revenue growth from combining the Eastman and Taminco businesses.  The going concern element represents the ability to earn a higher return on the combined assembled collection of assets and businesses of Taminco than if those assets and businesses were to be acquired and managed separately.  Other relevant elements of goodwill are the benefits of access to certain markets and work force. Goodwill from the Taminco acquisition has been preliminarily allocated to certain of the Company's reportable segments as set out in the table below. None of the goodwill is deductible for tax purposes.
	Goodwill	Goodwill by Segment
	(Dollars in millions)
	Additives & Functional Products	$	908
	Specialty Fluids & Intermediates	601
	Total	$	1,509
	Current liabilities consist primarily of trade payables, deferred tax liabilities, and accrued charges. Long-term liabilities are primarily deferred tax liabilities, pension and other postretirement welfare plan obligations, and asset retirement liabilities. Management also evaluated probable loss contingencies, including those for legal, asset retirement, and environmental matters, as prescribed under GAAP. Due to the lack of observable market inputs, assumed liabilities for asset retirement and environmental loss contingencies that were both probable and estimable were recorded based upon estimates of future cash outflows for such contingencies as of the acquisition date. See Note 13, "Environmental Matters and Asset Retirement Obligations", for more information.
	In 2014, the Company recognized $14 million in transaction costs, $1 million in integration costs, and $13 million in pre-close financing costs related to the acquisition. Transaction costs and integration costs were expensed as incurred and are included in the "Selling, general and administrative expenses" line item and pre-close financing costs are included in the "Other (income) charges, net" and "Net interest expense" line items in the Consolidated Statements of Earnings, Comprehensive Income, and Retained Earnings.  As required by purchase accounting, acquired inventories were marked to fair value. These inventories were sold in fourth quarter 2014 resulting in a $15 million increase in cost of sales.
	Beginning December 2014, the Company's consolidated results of operations included the results of the acquired Taminco businesses.  Since the date of the acquisition, sales revenue of $84 million and an operating loss of $9 million from the acquired Taminco businesses have been included in the Company's consolidated results of operations for 2014. The operating loss includes the additional costs of acquired inventories, transaction costs, integration costs, and pre-close financing costs.
	The unaudited pro forma financial results for years ended December 31, 2014 and 2013 combine the consolidated results of Eastman and Taminco giving effect to the acquisition of Taminco as if it had been completed on January 1, 2013, the beginning of the comparable annual reporting period prior to the year of acquisition.  Such unaudited pro forma financial results do not give pro forma effect to any other transaction or event. The unaudited pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition.  This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2013 or any other date.
	The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the fair value step-up and estimated useful lives of Taminco depreciable fixed assets and definite-life amortizable assets acquired in the transaction.  The unaudited pro forma results also include adjustments to net interest expense.  The provision for income taxes from continuing operations also has been adjusted for all periods, based upon the foregoing adjustments to historical results.
		For years ended December 31,
	(Unaudited, dollars in millions)	2014			2013
	Pro forma sales	$	10,819		$	10,550
	Pro forma earnings from continuing operations	834			1,101
	Unaudited pro forma earnings from continuing operations for 2013 have been adjusted to include certain items, such as pre-close financing, integration, and transaction costs historically recorded by Eastman and Taminco directly attributable to the acquisition, which will not have an ongoing impact.  These items include transaction, integration, and pre-close financing costs incurred by Eastman during 2014 as well as transaction costs incurred by Taminco prior to its acquisition by Eastman.  Additionally, the unaudited pro forma financial results for 2013 have been adjusted to reflect the additional costs of acquired inventories. Accordingly, these non-recurring costs have been eliminated from unaudited pro forma earnings from continuing operations for 2014.
	Commonwealth Laminating and Coating, Inc.
	On December 11, 2014, the Company acquired Commonwealth Laminating and Coating, Inc. ("Commonwealth") for a total cash purchase price of $438 million, prior to post-closing adjustments. The acquisition was accounted for as a business combination and is reported in the Advanced Materials ("AM") segment. The acquisition of Commonwealth strengthens the Company's window film product portfolio, adds industry leading protective film technology, and increases scale cost efficiencies.
	The following table summarizes the preliminary purchase price allocation for the Commonwealth acquisition, any subsequent adjustments are not expected to have a material impact on the Company's financial position or results of operations:
	Assets acquired and liabilities assumed
	(Dollars in millions)	As of December 11, 2014
	Current assets	$	51
	Machinery and equipment	38
	Goodwill	274
	Intangible assets	125
	Long-term liabilities	(50		)
	Total purchase price	$	438
	Current assets consist primarily of inventory acquired. Machinery and equipment acquired included a manufacturing operation in Martinsville, Virginia. Management valued machinery and equipment using the cost approach supported by published industry sources.
	Acquired intangible assets included customer relationships and developed technologies in the window film industry. Also acquired was the SunTek® brand name that is business-to-business in nature. Management valued intangible assets using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data for peer chemical companies.

	Brand name	12
	Total	$	125
	In connection with this acquisition, the Company recorded goodwill equal to the excess of the purchase price over the estimated fair value of net tangible and intangible assets acquired and liabilities assumed.  None of the goodwill is deductible for tax purposes.
	In 2014, the Company recognized $5 million and $2 million in transaction and integration costs, respectively, related to the acquisition. Transaction and integration costs were expensed as incurred and are included in the "Selling, general and administrative expenses" line item in the Consolidated Statements of Earnings, Comprehensive Income and Retained Earnings. As required by purchase accounting, acquired inventories were marked to fair value. Approximately one fifth of these inventories were sold in December 2014 resulting in a $1 million increase in cost of sales.
Beginning in December 2014, the Company's consolidated results of operations included the results of Commonwealth. Based on applicable accounting and reporting guidance, the acquisition is not material to the Company's consolidated financial statements; therefore, pro forma financial information has not been presented.
BP plc's Global Aviation Turbine Engine Oil Business
On June 2, 2014, the Company acquired BP plc's global aviation turbine engine oil business ("aviation turbine oil business") for a total cash purchase price of $283 million. The acquisition was accounted for as a business combination and is reported in the SFI segment. In combination with Eastman's Skydrol® aviation hydraulic fluids business, the acquired aviation turbine oil business enables Eastman to better supply the global aviation industry.
The purchase price allocation for the aviation turbine oil business acquisition is final as of December 31, 2014. Adjustments to the June 30, 2014 preliminary purchase price allocation of the aviation turbine oil business acquisition during 2014 are reflected in the Company's Consolidated Statements of Financial Position as of December 31, 2014 and are summarized in the table below. These adjustments are not material to the Company's financial position or results of operations for 2014. The following table summarizes the purchase price allocation for the aviation turbine oil business acquisition as of June 2, 2014, as previously reported at June 30, 2014, the net impact of adjustments during 2014, and the resulting finalized purchase price allocation for the aviation turbine oil business acquisition as of June 2, 2014 as reported at December 31, 2014.

Solutia Inc.
On July 2, 2012, the Company completed its acquisition of Solutia, a global leader in performance materials and specialty chemicals.  In the acquisition, each outstanding share of Solutia common stock was cancelled and converted automatically into the right to receive $22.00 in cash and 0.12 shares of Eastman common stock.  In total, 14.7 million shares of Eastman common stock were issued in the transaction.  The fair value of total consideration transferred was $4.8 billion, consisting of cash of $2.6 billion, net of cash acquired; equity in the form of Eastman stock of approximately $700 million; and the assumption and subsequent repayment of Solutia's debt at fair value of $1.5 billion.
The funding of the cash portion of the purchase price, repayment of Solutia's debt, and acquisition costs was provided primarily from borrowings, including the $2.3 billion net proceeds from the public offering of notes on June 5, 2012 and borrowings of $1.2 billion on July 2, 2012 under a five-year term loan agreement (the "Term Loan").  See Note 9, "Borrowings".
The purchase price allocation for the July 2, 2012 Solutia acquisition was finalized as of June 30, 2013. Updates to the December 31, 2012 preliminary purchase price allocation of the Solutia acquisition during second quarter 2013 for finalization of current and deferred income taxes were reflected in the Company's Consolidated Statements of Financial Position as of June 30, 2013 and are summarized in the table below. These adjustments were primarily for finalization of valuation allowances against Federal and state deferred tax assets in connection with the filing of the final Solutia consolidated federal tax return. These updates were not material to the Company's financial position or results of operations for 2012 or 2013.

The Company used the income, market, or cost approach (or a combination thereof) for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions.  Market participants are considered to be buyers and sellers unrelated to Eastman in the principal or most advantageous market for the asset or liability. For certain items, the carrying value was determined to be a reasonable approximation of fair value based on information available to Eastman management. The fair value of receivables acquired from Solutia on July 2, 2012 was $350 million, with gross contractual amounts receivable of $366 million. Acquired intangible assets were primarily customer relationships, trade names, and developed technologies.  Long-term liabilities were primarily Solutia's debt, which was repaid by Eastman at closing, deferred tax liabilities, environmental liabilities, and pension and other postretirement welfare plan obligations. The Company finalized the acquisition accounting related to the transaction during fourth quarter 2012 with the exception of income taxes which were completed during the second quarter 2013 and did not have a material impact on the Company's financial position or results of operations.
The acquisition of Solutia broadened Eastman's global presence, facilitated growth opportunities through enhanced access to markets such as the automotive and architectural industries, and expanded Eastman's portfolio of sustainable products.  In connection with the purchase, the Company recorded goodwill, equal to the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of liabilities assumed. The goodwill is attributed primarily to Solutia as a going concern and the fair value of expected cost synergies and revenues growth from combining the Eastman and Solutia businesses.  The going concern element represents the ability to earn a higher return on the combined assembled collection of assets and businesses of Solutia than if those assets and businesses were to be acquired and managed separately.  Other relevant elements of goodwill are the benefits of access to certain markets and work force. Goodwill from the Solutia acquisition has been allocated to certain of the Company's reportable segments as set forth in the table below. None of the goodwill is deductible for tax purposes.

Properties acquired included a number of manufacturing, sales, and distribution sites and related facilities, land and leased sites that include leasehold improvements, and machinery and equipment for use in manufacturing operations.  Management valued properties using the cost approach supported where available by observable market data which includes consideration of obsolescence.
Intangible assets acquired included a number of trade names and trademarks that are both business-to-business and business-to-consumer in nature, including Crystex®, Saflex®, and LLumar®.  Also acquired was technology related to products protected by a number of existing patents, patent applications, and trade secrets.  In addition to these intangible assets, the Company acquired a number of customer relationships in industries such as automotive tires and aviation. Management valued intangible assets using the relief from royalty and multi-period excess earnings methods, both forms of the income approach supported by observable market data for peer chemical companies.

Management estimated the fair market value of fixed-rate debt based on the viewpoint that the exit price approximated the entry price given the lack of observable market prices. Additionally, acquired interest rate swaps and foreign exchange contracts were terminated and settled immediately following the acquisition. Because these derivatives were recorded at fair value in the opening balance sheet, there were no gains or losses associated with these settlements.
Management also evaluated probable loss contingencies, including those for legal and environmental matters, as prescribed under GAAP. Due to the lack of observable market inputs, assumed liabilities for environmental loss contingencies that were both probable and estimable were recorded based upon estimates of future cash outflows for such contingencies as of the acquisition date. See Note 13, "Environmental Matters and Asset Retirement Obligations", for more information.
In 2013, the Company recognized $36 million in integration costs related to the acquisition. In 2012, the Company recognized $28 million in transaction costs, $16 million in integration costs, and $32 million in pre-close financing costs related to the acquisition. Transaction costs and integration costs were expensed as incurred and are included in the "Selling, general and administrative expenses" line item and pre-close financing costs are included in the "Other (income) charges, net" and "Net interest expense" line items in the Consolidated Statements of Earnings, Comprehensive Income, and Retained Earnings.  In 2012, there were $32 million in restructuring charges primarily for severance associated with the acquisition and integration of Solutia. As required by purchase accounting, acquired inventories were marked to fair value. These inventories were sold in 2012 resulting in a $79 million increase in cost of sales, net of the LIFO impact of these inventories, primarily in third quarter 2012.
Beginning third quarter 2012, the Company's consolidated results of operations included the results of the acquired Solutia businesses. Sales revenue of $969 million and an operating loss of $25 million from the acquired Solutia businesses were included in the Company's consolidated results of operations for 2012.
The unaudited pro forma financial results for the year ended December 31, 2012 combines the consolidated results of Eastman and Solutia giving effect to the acquisition of Solutia as if it had been completed on January 1, 2011, the beginning of the comparable annual reporting period prior to the year of acquisition.  Such unaudited pro forma financial results do not give pro forma effect to any other transaction or event. The unaudited pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition.  This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2011, or any other historical date.
The unaudited pro forma financial results include certain adjustments for additional depreciation and amortization expense based upon the fair value step-up and estimated useful lives of Solutia depreciable fixed assets and definite-life amortizable assets acquired in the transaction.  The unaudited pro forma results also include adjustments to net interest expense and elimination of early debt extinguishment costs historically recorded by Solutia based upon the retirement of Solutia's debt and issuance of additional debt related to the transaction.  The provision for income taxes from continuing operations has also been adjusted, based upon the foregoing adjustments to historical results, as well as the elimination of historical net changes in valuation allowances against certain deferred tax assets of Solutia.
Additionally, Solutia's historical consolidated results have been retrospectively adjusted for the change in accounting methodology for pension and other postretirement benefit plans actuarial gains and losses adopted by Eastman during first quarter 2012.
(Unaudited, dollars in millions)	2012
Pro forma sales	$	9,120
Pro forma earnings from continuing operations including noncontrolling interest	649
Non-recurring costs directly attributable to the acquisition, which did not have an ongoing impact, are excluded from unaudited pro forma earnings from continuing operations including noncontrolling interest in 2012.  These items include transaction, integration, pre-close financing, and restructuring costs incurred by Eastman during 2012, as well as transaction costs of $45 million and expenses of $19 million for the accelerated vesting of stock-based compensation awards incurred by Solutia prior to its acquisition by Eastman.  Additionally, the non-recurring costs of acquired inventories have been eliminated from unaudited pro forma earnings from continuing operations for 2012.

	The 2014 effective tax rate of 24 percent reflects continued benefit from the integration of Eastman and Solutia business operations and legal entity structures. The 2014 effective tax rate also reflects the benefit from the one-year extension of favorable U.S. Federal tax provisions in December 2014, which resulted in a net benefit of $15 million primarily related to R&D credits described below and deferral of certain earnings of foreign subsidiaries from U.S. income taxes.
	The 2013 effective tax rate of 30 percent reflected the positive impacts of integrating the Eastman and Solutia business operations and legal entity structures, a $14 million tax benefit primarily due to adjustments to the tax provision to reflect the finalization of the 2012 consolidated U.S. Federal income tax return, a $14 million benefit for the finalization of foreign tax audits, and the enactment of the American Taxpayer Relief Act of 2012 in January 2013 which resulted in a $10 million benefit primarily related to an R&D tax credit.
	The 2012 effective tax rate of 32 percent reflected a $12 million tax benefit for favorable audit settlements and the expiration of the relevant statute of limitations, a $9 million tax benefit for additional state tax credits, and a $5 million tax charge for nondeductible transaction costs.

Unremitted earnings of subsidiaries outside the United States, considered to be reinvested indefinitely, totaled approximately $1.6 billion at December 31, 2014.  It is not practicable to determine the deferred tax liability for temporary differences related to those unremitted earnings.
For certain consolidated foreign subsidiaries, income and losses directly flow through to taxable income in the United States. These entities are also subject to taxation in the foreign tax jurisdictions. Net operating loss carryforwards exist to offset future taxable income in foreign tax jurisdictions and valuation allowances are provided to reduce deferred related tax assets if it is more likely than not that this benefit will not be realized. Changes in the estimated realizable amount of deferred tax assets associated with net operating losses for these entities could result in changes in the deferred tax asset valuation allowance in the foreign tax jurisdiction. At the same time, because these entities are also subject to tax in the United States, a deferred tax liability for the expected future taxable income will be established concurrently. Therefore, the impact of any reversal of valuation allowances on consolidated income tax expense will be only to the extent that there are differences between the United States statutory tax rate and the tax rate in the foreign jurisdiction.  A valuation allowance of $26 million at December 31, 2014, has been provided against the deferred tax asset resulting from these operating loss carryforwards.
At December 31, 2014, foreign net operating loss carryforwards totaled $640 million.  Of this total, $122 million will expire in 3 to 20 years; and $518 million have no expiration date. A valuation allowance of approximately $130 million has been provided against such net operating loss carryforwards.
At December 31, 2014, federal net operating loss carryforwards of $714 million were available to offset future taxable income, which expire from 2026 to 2031. At December 31, 2014, foreign tax credit carryforwards of approximately $185 million were available to reduce possible future U.S. income taxes and which expire from 2018 to 2024.
A full valuation allowance of $50 million has been provided against the U.S. deferred tax assets for the capital loss carryforward and a partial valuation allowance of $53 million has been provided for Solutia's state net operating loss carryforwards. The valuation allowance will be retained until there is sufficient positive evidence to conclude that it is more likely than not that the deferred tax assets will be realized or the related statute expires.
As a result of the Solutia acquisition transaction, Solutia realized a change of ownership for purposes of Section 382 of the Internal Revenue Code. Management does not currently expect this change to significantly limit the Company's ability to utilize Solutia's U.S. net operating loss or foreign tax credit carryforwards estimated to be approximately $685 million and $180 million, respectively, at December 31, 2014.

As of December 31, 2014, 2013, and 2012, $117 million, $51 million, and $65 million, respectively, of unrecognized tax benefits would, if recognized, impact the Company's effective tax rate.
Interest, net of tax, related to unrecognized tax benefits is recorded as a component of income tax expense.  As of January 1, 2014, the Company had accrued a liability of $4 million for interest, net of tax, and had $3 million for tax penalties, net of tax benefit.  During 2014, the Company recognized $1 million of expense for interest, net of tax, and no penalties associated with unrecognized tax benefits, offset by $1 million of income for interest, net of tax, associated with expiration of statute of limitations.  At December 31, 2014, the Company had accrued balances of $4 million for interest, net of tax benefit, and $3 million for penalties, net of tax benefit.
As of January 1, 2013, the Company had accrued a liability of approximately $5 million for interest, net of tax, and had $3 million for tax penalties, net of tax benefit.  During 2013, the Company recognized $1 million of expense for interest, net of tax, and no penalties associated with unrecognized tax benefits, offset by $2 million of income for interest, net of tax, associated with favorable audit settlements.  At December 31, 2013, the Company had accrued balances of $4 million for interest, net of tax benefit, and $3 million for penalties, net of tax benefit.
The Company files income tax returns in the United States and various state and foreign jurisdictions.  The Company is no longer subject to U.S. Federal income tax examinations by tax authorities for years before 2011 and 2002 for Eastman and Solutia, respectively. With few exceptions, Eastman is no longer subject to state and local income tax examinations by tax authorities for years before 2009. Solutia, Inc. and related subsidiaries are no longer subject to state and local income tax examinations for years before 2002. With few exceptions, the Company is no longer subject to foreign income tax examinations by tax authorities for tax years before 2006.
It is reasonably possible that, within the next twelve months, as a result of the resolution of federal, state, and foreign examinations and appeals, and the expiration of various statutes of limitation, unrecognized tax benefits will decrease by a range of $0 to $17 million.

Proceeds from the sale of the notes, net of original issue discounts, issuance costs, and the monetization of interest rate swaps, was $1.96 billion.
	On May 15, 2014, the Company issued public debt securities consisting of 4.65% notes due 2044 in the principal amount of $500 million. Proceeds from the sale of the notes, net of transaction costs, were $490 million.
	On June 5, 2012, the Company issued public debt securities consisting of 2.4% notes due 2017 in the principal amount of $1.0 billion, 3.6% notes due 2022 in the principal amount of $900 million, and 4.8% notes due 2042 in the principal amount of $500 million.  Proceeds from the sale of the notes, net of original issue discounts, issuance costs, and the monetization of interest rate swaps, were $2.3 billion.  Proceeds from these borrowings were used to pay, in part, the cash portion of the purchase price to complete the Solutia acquisition, repay Solutia debt, and pay acquisition costs.
	Credit Facility and Commercial Paper Borrowings
	On October 9, 2014, Eastman entered into a $1.0 billion five-year Term Loan Agreement. The Company borrowed the entire amount under the Term Loan Agreement on December 5, 2014. Borrowings under the Term Loan Agreement were used to pay a part of the purchase price for the acquisition of Taminco, which included the repayment of outstanding borrowings of Taminco, and a portion of the acquisition fees and expenses. 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.
	In addition, on October 9, 2014, Eastman entered into a $1.75 billion Senior Bridge Loan Credit Agreement (the "Bridge Loan Agreement"). The Bridge Loan Agreement remained undrawn and was terminated following receipt of proceeds from the public sale of debt securities on November 20, 2014.
	In October 2014, the Company entered into a $1.25 billion revolving credit agreement (the "Credit Facility") expiring October 2019.  The Credit Facility amends and extends, and has terms substantially similar to, the $1.0 billion revolving credit agreement entered into in October 2013.  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 December 31, 2014 and December 31, 2013, 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 December 31, 2014 the Company's commercial paper borrowings were $235 million with a weighted average interest rate of 0.47 percent. At December 31, 2013 the Company's commercial paper borrowings were $425 million with a weighted average interest rate of 0.35 percent.
	In August 2014, the Company amended a $250 million line of credit under its accounts receivable securitization agreement (the "A/R Facility"), extending the maturity to April 2017. The amended A/R Facility has terms substantially similar to the $250 million accounts receivable securitization agreement previously expiring in April 2016. 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 December 31, 2014 and December 31, 2013 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 $1,265 million and $825 million as of December 31, 2014 and December 31, 2013, 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 December 31, 2014 and December 31, 2013 under the fair value hierarchy as defined in the accounting policies in Note 1, "Significant Accounting Policies".  The fair value for fixed-rate borrowings is based on current market prices and is classified in Level 1.  The fair value for the Company's floating-rate borrowings, which relate to the Term Loan Agreement, the A/R Facility, commercial paper, and capital leases, equals the carrying value and is classified within 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.
	In 2014, the Company implemented changes to its risk management framework that included changes in the horizon over which commodity related market risks are managed. Beginning in third quarter 2014, the period over which the Company hedges commodity price risks using derivative financial instruments was increased from a maximum of three years to a maximum of five years beyond its current fiscal year. The Company weights its hedge portfolio more heavily in the first year with declining coverage over the remaining periods.
	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 December 31, 2014, the total notional amount of the Company's interest rate swaps was $275 million. As of December 31, 2013, the Company had no fair value hedges.

	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.
	Foreign Currency Exchange Rate Hedging
	The Company manufactures and sells its products in a number of countries throughout the world and, as a result, is exposed to changes in foreign currency exchange rates.  To manage the volatility relating to these exposures, the Company nets the exposures on a consolidated basis to take advantage of natural offsets.  To manage the remaining exposure, the Company enters into currency options and forwards from time to time to hedge probable anticipated, but not yet committed, export sales and purchase transactions expected within no longer than five years and denominated in foreign currencies (principally the euro and Japanese yen) and forward exchange contracts to hedge certain firm commitments denominated in foreign currencies.  These contracts are designated as cash flow hedges.  The MTM gains or losses on qualifying hedges are included in accumulated other comprehensive income (loss) to the extent effective, and reclassified into sales in the period during which the hedged transaction affects earnings.
	Commodity Hedging
	Certain raw material and energy sources used by the Company, as well as sales of certain commodity products by the Company, are subject to price volatility caused by weather, supply and demand conditions, economic variables and other unpredictable factors.  These commodity and energy costs are primarily related to propane, ethane, natural gas, paraxylene, ethylene, and benzene. From time to time to mitigate expected fluctuations in market prices, the Company enters into option and forward contracts.  These contracts are designated as cash flow hedges.  The MTM gains or losses on qualifying hedges are included in accumulated other comprehensive income (loss) to the extent effective, and reclassified into cost of sales (for commodity purchases) and sales (for commodity sales) in the period during which the hedged transaction affects earnings.
	Interest Rate Hedging
	The Company's policy is to manage interest expense using a mix of fixed and variable rate debt.  To manage this mix effectively, the Company from time to time enters into interest rate swaps in which the Company agrees to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount.  These swaps are designated as hedges of the fair value of the underlying debt obligations and the interest rate differential is reflected as an adjustment to interest expense over the life of the swaps.  As these instruments are 100 percent effective, there is no impact on earnings due to hedge ineffectiveness.
	From time to time, the Company also utilizes interest rate derivative instruments, primarily forward starting swaps and Treasury locks, to hedge the Company's exposure to movements in interest rates prior to anticipated debt offerings.  These instruments are designated as cash flow hedges and are typically 100 percent effective.  As a result, there is no current impact on earnings due to hedge ineffectiveness.
	The MTM gains or losses on these hedges are included in accumulated other comprehensive income (loss) to the extent effective, and are reclassified into interest expense over the term of the related debt instruments.

	Hedging Summary
	At December 31, 2014 and 2013, pre-tax monetized positions and MTM gains and losses from raw materials and energy, currency, and certain interest rate hedges that were included in accumulated other comprehensive income totaled approximately $432 million in losses and $62 million in losses, respectively.  Losses increased in 2014 compared to 2013 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. Included in 2014 and 2013 were losses on settlement of forward starting interest rate swaps related to the issuance of debt for the Solutia acquisition.  If realized, approximately $144 million in pre-tax losses will be reclassified into earnings during the next 12 months.  Ineffective portions of hedges are immediately recognized in cost of sales or other (income) charges, net.  In 2014, the Company recognized $6 million in pre-tax losses for ineffectiveness on the commodity hedging portfolio. There were no gains or losses related to the ineffective portion of hedges recognized in 2013.
	The gains or losses on nonqualifying derivatives or derivatives that are not designated as hedges are marked to market in the line item "Other (income) charges, net" of the 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 approximately $3 million net loss and $4 million net gain on nonqualifying derivatives during 2014 and 2013, respectively. The Company had no nonqualifying derivatives or derivatives that are not designated as hedges as of December 31, 2014 and December 31, 2013.

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.
From time to time, the Company holds Level 3 assets for commodity hedges.  The fair values of Level 3 instruments are determined using pricing data similar to that used in Level 2 financial instruments described above, and reflect adjustments for less liquid markets or longer contractual terms.  Level 3 hedges typically will mature within one year or less.  The Company determines the fair value of Level 3 ethylene derivative forward contracts using an average of unadjusted forward ethylene prices provided by industry recognized experts to value its ethylene positions.
The table below presents a rollforward of activity for these assets for the period ended December 31, 2014 and December 31, 2013:

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 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 $129 million and a derivative in a net liability position of $498 million as of December 31, 2014. The Company does not have any cash collateral due under such agreements.

Compensation and Retirement Disclosure [Abstract]
RETIREMENT PLANS	RETIREMENT PLANS
	As described in more detail below, Eastman offers various postretirement benefits to its employees.
	Defined Contribution Plans
	The Company sponsors a defined contribution employee stock ownership plan (the "ESOP"), which is a component of the Eastman Investment Plan and Employee Stock Ownership Plan ("EIP/ESOP"), a plan under Section 401(a) of the Internal Revenue Code.  Eastman made a contribution in February 2015 to the EIP/ESOP for substantially all U.S. employees equal to 5 percent of their eligible compensation for the 2014 plan year.  Employees may allocate contributions to other investment funds within the EIP from the ESOP at any time without restrictions.  Allocated shares in the ESOP totaled 2,197,740; 2,289,618; and 2,410,806 shares as of December 31, 2014, 2013, and 2012, respectively.  Dividends on shares held by the EIP/ESOP are charged to retained earnings.  All shares held by the EIP/ESOP are treated as outstanding in computing earnings per share.
	In 2006, the Company amended its EIP/ESOP to provide a Company match of 50 percent of the first 7 percent of an employee's compensation contributed to the plan for employees who are hired on or after January 1, 2007.  Employees who are hired on or after January 1, 2007, are also eligible for the contribution to the ESOP as described above.
	Charges for domestic contributions to the EIP/ESOP were $56 million, $43 million, and $40 million for 2014, 2013, and 2012, respectively.
	Defined Benefit Pension Plans and Other Postretirement Benefit Plans
	Pension Plans
	Eastman maintains defined benefit pension plans that provide eligible employees with retirement benefits.
	Effective January 1, 2000, the Company's Eastman Retirement Assistance Plan, a U.S. defined benefit pension plan, was amended.  Employees' accrued pension benefits earned prior to January 1, 2000 are calculated based on previous plan provisions using the employee's age, years of service, and final average compensation as defined in the plans.  The amended plan uses a pension equity formula to calculate an employee's retirement benefits from January 1, 2000 forward.  Benefits payable will be the combined pre-2000 and post-1999 benefits.  Employees hired on or after January 1, 2007 are not eligible to participate in Eastman's U.S. defined benefit pension plans.
	In December 2014, as part of its acquisition of Taminco, the Company assumed Taminco's non-U.S. defined benefit pension plans in Belgium and Finland.  For more information on this acquisition, see Note 2, "Acquisitions".
	In July 2012, as part of its acquisition of Solutia, the Company assumed Solutia's U.S. and non-U.S. defined benefit pension plans.  Prior to the acquisition, the U.S. plans had been closed to new participants and were no longer accruing additional benefits.  For more information on these acquisitions, see Note 2, "Acquisitions".
	Benefits are paid to employees from trust funds.  Contributions to the trust funds are made as permitted by laws and regulations.  The pension trust funds do not directly own any of the Company's common stock.
	Pension coverage for employees of Eastman's non-U.S. operations is provided, to the extent deemed appropriate, through separate plans.  The Company systematically provides for obligations under such plans by depositing funds with trustees, under insurance policies, or by book reserves.
	Other Postretirement Benefit Plans
	Under its other postretirement benefit plans, Eastman provides a subsidy for life insurance, health care, and dental benefits to eligible retirees hired prior to January 1, 2007, and a subsidy for health care and dental benefits to retirees' eligible survivors.  In general, Eastman provides those benefits to retirees eligible under the Company's U.S. plans.  Similar benefits are also made available to retirees of Holston Defense Corporation, a wholly-owned subsidiary of the Company that, prior to January 1, 1999, operated a government-owned ammunition plant.
	Employees in the U.S. hired on or after January 1, 2007 do not have access to postretirement health care benefits.  A few of the Company's non-U.S. operations have supplemental health benefit plans for certain retirees, the cost of which is not significant to the Company.
	In December 2014, as part of its acquisition of Taminco, the Company assumed Taminco's U.S. postretirement benefit plan.  For more information on this acquisition, see Note 2, "Acquisitions".
	In July 2012, as part of its acquisition of Solutia, the Company assumed Solutia's postretirement benefit plans which included a voluntary employees' beneficiary association ("VEBA") retiree trust.  For more information on this acquisition, see Note 2, "Acquisitions".
	Below is a summary balance sheet of the change in plan assets during 2014 and 2013, the funded status of the plans, amounts recognized in the Consolidated Statements of Financial Position, and a summary of amounts recognized in accumulated other comprehensive income.

In third quarter 2013, the Company changed life insurance benefits provided to future retirees by the Eastman other postretirement benefit plan which triggered an interim remeasurement of this other postretirement benefit plan obligation. The remeasurement resulted in a reduction in the accumulated postretirement benefit obligation of approximately $47 million which will be amortized as a prior service credit from Accumulated Other Comprehensive Income over 8 years. The remeasurement of the plan also resulted in a mark-to-market actuarial gain of $86 million in third quarter 2013. The actuarial gain was primarily due to a higher assumed discount rate of 4.72 percent in third quarter 2013 compared to 4.01 percent at December 31, 2012. The higher assumed discount rate is reflective of changes in global market conditions and interest rates on high-grade corporate bonds.
The estimated prior service credit for the U.S. pension and other postretirement benefit plans that will be amortized from Accumulated Other Comprehensive Income into net periodic cost in 2015 is $4 million and $24 million, respectively.
The assumptions used to develop the projected benefit obligation for the Company's significant U.S. and non-U.S. defined benefit pension plans and U.S. postretirement benefit plans are provided in the following tables.

A seven and one-half percent rate of increase in per capita cost of covered health care benefits is assumed for 2015.  The rate is assumed to decrease gradually to five percent in 2020 and remain at that level thereafter.  A one percent increase or decrease in health care cost trend would have had no material impact on the 2014 service and interest costs or the 2014 benefit obligation, because the Company's contributions for benefits are fixed.
The Company performed a five year experience study on assumptions for the U.S. plans in 2014 which included a review of the mortality tables. The Company uses the RP-2000 table with scale AA static improvement scale and no collar adjustment. As a result of the study, the Company will not change to the recently published RP-2014 table as the current RP-2000 table with scale AA more closely aligns with the Company's experience.
The fair value of plan assets for the U.S. pension plans at December 31, 2014 and 2013 was $2.0 billion and $1.9 billion, respectively, while the fair value of plan assets at December 31, 2014 and 2013 for non-U.S. pension plans was $699 million and $658 million, respectively.  At December 31, 2014 and 2013, the expected weighted-average long-term rate of return on U.S pension plan assets was 7.78 percent and 7.83 percent, respectively.  The expected weighted-average long-term rate of return on non-U.S. pension plans assets was 5.50 percent and 5.78 percent at December 31, 2014 and 2013, respectively.
The following charts reflect the fair value of the defined benefit pension plans assets as of December 31, 2014 and 2013.

The Company's investment strategy for its defined benefit pension plans is to maximize the long-term rate of return on plan assets within an acceptable level of risk in order to meet or exceed the plan's actuarially assumed long-term rate of return and to minimize the cost of providing pension benefits.  A periodic asset/liability study is conducted in order to assist in the determination and, if necessary, modification of the appropriate long-term investment policy for the plan.  The investment policy establishes a target allocation range for each asset class and the fund is managed within those ranges.  The plans use a number of investment approaches including investments in equity, real estate, and fixed income funds in which the underlying securities are marketable in order to achieve this target allocation.  The plans also invest in private equity and other funds.  Diversification is created through investment across various asset classes, geographies, fund managers, and individual securities.  This investment process provides for a well-diversified portfolio with no significant concentration of risk.  The investment process is monitored by an investment committee comprised of various senior executives from within Eastman.
In December 2014, as part of its acquisition of Taminco, the Company assumed Taminco's non-U.S. defined benefit pension plans in Belgium and Finland. The pension plans' assets consist of guaranteed investment contracts with an insurance company.
The Company also assumed Taminco's U.S. postretirement benefit plan which has no plan assets.
In July 2012, as part of its acquisition of Solutia, the Company assumed Solutia's defined benefit pension and other postretirement benefit plans. The Solutia defined benefit pension plans adhere to the Company's defined benefit plan investment strategy. The Solutia defined benefit pension plans also utilize a dynamic de-risking strategy to shift from growth assets to liability matching assets as the plan's funded status improves. The investment strategy with respect to Solutia's other postretirement benefits plan is to invest in an intermediate-term, well diversified, high quality investment instruments, with a primary objective of capital preservation.
The expected rate of return for all plans was determined primarily by modeling the expected long-term rates of return for the categories of investments held by the plans and the targeted allocation percentage against various potential economic scenarios.
The Company funded its U.S. defined benefit pension plans in the amount of $120 million in both 2014 and 2013. For 2015, there are no minimum required cash contributions for the U.S. defined benefit pension plans under the Employee Retirement Income Security Act of 1974, as amended, and the Internal Revenue Code of 1986, as amended.
Benefits expected to be paid from pension plans and benefits, net of participant contributions, expected to be paid for postretirement benefit obligations are as follows:

	Purchase Obligations and Lease Commitments
	The Company had various purchase obligations at December 31, 2014 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 approximately $309 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. Rental expense, net of sublease income, was $80 million, $73 million, and $61 million in 2014, 2013, and 2012, respectively.
	The obligations described above, and long-term debt repayment obligations, are summarized in the following table:

	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 December 31, 2014 totaled $121 million and consisted primarily of leases for railcars and Company aircraft and will expire beginning in 2016.  Management believes, based on current facts and circumstances, 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 joint venture partners, suppliers, customers, 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 between 1 and 30 years with maximum potential future payments of approximately $29 million in the aggregate, with none of these guarantees individually significant to the Company's operating results, financial position, or liquidity.  The Company's current expectation is that future payment or performance related to non-performance under other guarantees is considered remote.

Environmental Matters [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".  The Company's total reserve for environmental contingencies was $345 million and $368 million at December 31, 2014 and 2013, respectively.  At December 31, 2014 and 2013, this reserve included $10 million and $9 million, respectively, related to sites previously closed and impaired by Eastman, as well as sites that have been divested by Eastman but for which the Company retains the environmental liability.
	Estimated future environmental expenditures for remediation costs ranged from the minimum or best estimate of $324 million to the maximum of $548 million and from the minimum or best estimate of $341 million to the maximum of $581 million at December 31, 2014 and 2013, respectively.  The maximum estimated future costs are considered to be reasonably possible and include the amounts accrued at both December 31, 2014 and 2013.  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 expected sharing of costs, the availability of legal defenses, and the Company's preliminary assessment of actions that may be required, 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 asset retirement obligation costs were $21 million and $27 million at December 31, 2014 and 2013, respectively.
	Reserves for environmental remediation that management believes to be probable and estimable are recorded as current and long-term liabilities in the 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 (income) charges, net, and are summarized below:
	(Dollars in millions)
	Balance at December 31, 2013	$	341
	Assumed remediation reserve from acquisitions	2
	Changes in estimates recorded to earnings and other	8
	Cash reductions	(27		)
	Balance at December 31, 2014	$	324
	The Company's total environmental reserve for environmental contingencies, including remediation costs and asset retirement obligations, is recorded in the Consolidated Statements of Financial Position as follows:
		December 31,
	(Dollars in millions)	2014			2013
	Environmental contingent liabilities, current	$	35		$	40
	Environmental contingent liabilities, long-term	310			328
	Total	$	345		$	368
	Additionally, costs of certain remediation projects included in the assumed environmental reserve are subject to a cost-sharing arrangement with Monsanto Company ("Monsanto") under the provisions of the Amended and Restated Settlement Agreement effective February 28, 2008 (the "Effective Date"), into which Solutia entered with Monsanto upon its emergence from bankruptcy (the "Monsanto Settlement Agreement"). Under the provisions of the Monsanto Settlement Agreement, the Company shares responsibility with Monsanto for remediation at certain locations outside of the boundaries of plant sites in Anniston, Alabama and Sauget, Illinois (the "Shared Sites"). The Company is responsible for the funding of environmental liabilities at the Shared Sites up to a total of $325 million from the Effective Date. If remediation costs for the Shared Sites exceed this amount, such costs will thereafter be shared equally between the Company and Monsanto. Including payments by Solutia prior to its acquisition by Eastman, $64 million had been paid for costs at the Shared Sites as of December 31, 2014. As of December 31, 2014, an additional $212 million has been accrued for estimated future remediation costs at the Shared Sites, over a period of thirty years.
	Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination.  The cost of operating and maintaining environmental control facilities is charged to expense. The Company's cash expenditures related to environmental protection and improvement were $319 million, $285 million, and $262 million in 2014, 2013, and 2012, respectively.  These amounts were primarily for operating costs associated with environmental protection equipment and facilities, but also included $79 million and $53 million in expenditures for engineering and construction in 2014 and 2013, respectively.
	The Company also has contractual obligations that include 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 December 31, 2014.

	The Company is authorized to issue 400 million shares of all classes of stock, of which 50 million may be preferred stock, par value $0.01 per share, and 350 million may be common stock, par value $0.01 per share.  The Company declared dividends per share of $1.45 in 2014, $1.25 in 2013, and $1.08 in 2012.
	On July 2, 2012, as part of the Company's acquisition of Solutia, the Company issued 14.7 million shares of Eastman common stock and 4,481,250 warrants to purchase 0.12 shares of Eastman common stock and $22.00 cash per warrant upon payment of the warrant exercise price of $29.70. The warrants expired on February 27, 2013. For more information, see Note 2, "Acquisitions". There were no warrants outstanding as of December 31, 2013.
	The Company established a benefit security trust in 1997 to provide a degree of financial security for unfunded obligations under certain unfunded plans and contributed to the trust a warrant to purchase up to 6 million shares of common stock of the Company for par value.  The warrant, which remains outstanding, is exercisable by the trustee if the Company does not meet certain funding obligations, which obligations would be triggered by certain occurrences, including a change in control or potential change in control, as defined, or failure by the Company to meet its payment obligations under certain covered unfunded plans.  Such warrant is excluded from the computation of diluted earnings per share because the conditions upon which the warrant becomes exercisable have not been met.
	The additions to paid-in capital in both 2014 and 2013 are primarily for compensation expense of equity awards and employee stock option exercises. The additions in 2012 are primarily for shares issued as part of the acquisition of Solutia and employee stock option exercises and compensation expense of equity awards.

	2014
	In 2014, there were net asset impairments and restructuring charges of $77 million.
	In 2014, asset impairments of $18 million and restructuring charges, including severance, of $24 million were recognized in the AFP segment for costs of the closure of a Crystex® R&D facility in France.
	As a result of the annual impairment testing of indefinite-lived intangible assets, in third quarter 2014 the Company recognized an intangible asset impairment of $22 million in the AFP segment to adjust the carrying value of the Crystex® tradename to the estimated fair value. This impairment resulted from a decrease in projected revenue since the tradename was acquired from Solutia in 2012. The estimated fair value was determined using an income approach, specifically the relief from royalty method.
	In addition, during 2014, a change in estimate of certain costs for the fourth quarter 2012 termination of the operating agreement for the São Jose dos Campos, Brazil site resulted in a restructuring charge of $5 million to previously recognized asset impairments and restructuring charges.
	During 2014, the Company recognized gains from the sales of previously impaired assets at the former Photovoltaics production facility in Germany and a former polymers production facility in China of $5 million and $2 million, respectively.
	In 2014, charges in the AM segment included $10 million of asset impairments, including intangible assets, and $2 million of restructuring charges primarily due to the closure of a production facility in Taiwan for the Flexvue® product line. 2014 also included $5 million of restructuring charges for severance associated with the integration of the acquired Solutia businesses.
	2013
	In 2013, there were $76 million in asset impairments and restructuring charges and gains, net, including $23 million of restructuring charges primarily for severance associated with the integration of Solutia. For additional information related to the acquisition of Solutia, see Note 2, "Acquisitions".
	During 2013, management decided not to continue its Perennial Wood™ growth initiative. This resulted in asset impairment charges of $16 million and restructuring charges of $14 million primarily for inventory and contract termination costs. Also during fourth quarter 2013, management decided to terminate efforts to develop a continuous resin process in Kuantan, Malaysia and Antwerp, Belgium.  This resulted in asset impairment charges of $4 million.
	During 2013, management decided to shut-down the Photovoltaics product line, including the primary production facility in Germany. This resulted in the Company recognizing asset impairments of $8 million and restructuring charges of $6 million including charges for severance.
	During 2013, management also approved and recorded severance charges of $6 million primarily for a voluntary separation plan for certain employees.
	In addition, during 2013, a change in estimate for certain costs for the fourth quarter 2012 termination of the operating agreement for the São Jose dos Campos, Brazil site resulted in a reduction of $4 million to previously recorded asset impairments and restructuring charges.
	2012
	In 2012, there were $120 million in asset impairments and restructuring charges and gains, net.
	During 2012, the Company terminated an operating agreement at the acquired Solutia facility in São Jose dos Campos, Brazil, which resulted in asset impairments and restructuring charges of $35 million. Restructuring charges for the shutdown of manufacturing activities at this site included contract termination costs for severance and other required costs under the operating agreement.  Additionally, the Company recorded asset impairments for long-lived assets at the site, based on fair value indicators.
	During 2012, management approved the closure of a production facility in China. Based on business analysis completed in fourth quarter, the Company concluded the production of the related product lines would be most efficiently performed in its Kingsport, Tennessee facility. This resulted in the Company recognizing asset impairment and restructuring charges of $6 million.
	During 2012, acquisition related restructuring charges of $32 million were recorded primarily for severance costs associated with the acquisition and integration of Solutia.
	During 2012, the Company ceased R&D activities for renewable chemicals at a site it acquired in 2011, resulting in asset impairments and restructuring charges of $4 million.
	During 2012, the Company recognized asset impairments of $17 million due to a change in approach to address recently finalized boiler air emissions regulations. The Company had incurred engineering costs associated with required modifications for its existing steam and electric generation capacity. However, based on the then current availability of natural gas and the lower cost of operation, management determined that conversion to natural gas fueled boilers was more cost efficient. The Company entered into long-term natural gas supply agreements with a third party in fourth quarter 2012, triggering the impairment of the project.
	During 2012, management decided to cease production of certain products in its Perennial Wood™ growth initiative.  As a result, a restructuring charge of $17 million was recognized for inventory costs in excess of recoverable value on these certain product lines and to accrue for losses on take-or-pay contracts with third parties.  An analysis was performed to determine what, if any, impairment may be required for the associated fixed assets.  Based on the expected life of the assets and intended uses within the Company's continuing acetylation initiatives, there was no impairment.
	The Company also recognized asset impairments related to land retained from the previously discontinued industrial gasification project. Based on fair value indicators, the carrying value of the Beaumont land was reduced by $6 million.

SHARE-BASED COMPENSATION PLANS AND AWARDS	SHARE-BASED COMPENSATION PLANS AND AWARDS
	2012 Omnibus Stock Compensation Plan
	Eastman's 2012 Omnibus Stock Compensation Plan ("2012 Omnibus Plan") was approved by stockholders at the May 3, 2012 Annual Meeting of Stockholders and shall remain in effect until its fifth anniversary.  The 2012 Omnibus Plan authorizes the Compensation and Management Development Committee of the Board of Directors to: grant awards, designate participants, determine the types and numbers of awards, determine the terms and conditions of awards and determine the form of award settlement.  Under the 2012 Omnibus Plan, the aggregate number of shares reserved and available for issuance is 10 million, which will consist of a number of shares not previously authorized for issuance under any other plan.  The number of shares covered by an award is counted against this share reserve as of the grant date of the award.  Shares covered by full value awards (e.g. performance shares and restricted stock awards) are counted against the total number of shares available for issuance or delivery under the plan as 2.5 shares for every one share covered by the award. Any stock distributed pursuant to an award may consist of, in whole or in part, authorized and unissued stock, treasury stock, or stock purchased on the open market.  Under the 2012 Omnibus Plan and previous plans, the forms of awards have included:  restricted stock and restricted stock units, stock options, stock appreciation rights ("SARs"), and performance shares.  The 2012 Omnibus Plan is flexible as to the number of specific forms of awards, but provides that stock options and SARs are to be granted at an exercise price not less than 100 percent of the per share fair market value on the date of the grant.
	Director Stock Compensation Subplan
	Eastman's 2013 Director Stock Compensation Subplan ("Directors' Subplan"), a component of the 2012 Omnibus Plan, remains in effect until terminated by the Board of Directors or the earlier termination of the 2012 Omnibus Plan.  The Directors' Subplan provides for structured awards of restricted shares to non-employee members of the Board of Directors.  Restricted shares awarded under the Directors' Subplan are subject to the same terms and conditions of the 2012 Omnibus Plan.  The Directors' Subplan does not constitute a separate source of shares for grant of equity awards and all shares awarded are part of the 10 million shares authorized under the 2012 Omnibus Plan.  Shares of restricted stock are granted on the first day of a non-employee director's initial term of service and shares of restricted stock are granted each year to each non-employee director on the date of the annual meeting of stockholders.
	General
	The Company is authorized by the Board of Directors under the 2012 Omnibus Plan to provide grants to employees and non-employee members of the Board of Directors.  It has been the Company's practice to issue new shares rather than treasury shares for equity awards that require settlement by the issuance of common stock and to withhold or accept back shares awarded to cover the related income tax obligations of employee participants.  Shares of unrestricted common stock owned by non-employee directors are not withheld or acquired to satisfy the withholding obligation related to their income taxes.  Shares of unrestricted common stock owned by specified senior management level employees are accepted by the Company to pay the exercise price of stock options in accordance with the terms and conditions of their awards.
	For 2014, 2013, and 2012, total share-based compensation expense (before tax) of approximately $28 million, $40 million, and $28 million, respectively, was recognized in selling, general and administrative expense in the Consolidated Statements of Earnings for all share-based awards of which approximately $4 million, $5 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 2014 and 2013, approximately $1 million and $3 million, respectively, of stock option compensation expense was recognized due to qualifying termination eligibility preceding the requisite vesting period.
	Stock Option Awards
	Options have been granted on an annual basis to non-employee directors under the Directors' Subplan and predecessor plans and by the Compensation and Management Development Committee of the Board of Directors under the 2012 Omnibus Plan and predecessor plans to employees.  Option awards 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 weighted average assumptions used in the determination of fair value for stock options awarded in 2014 and 2013 are provided in the table below. There were no stock options granted in 2012.
	Assumptions		2014	2013
	Expected volatility rate		25.82%	34.90%
	Expected dividend yield		1.70%	1.97%
	Average risk-free interest rate		1.44%	0.77%
	Expected forfeiture rate		0.75%	0.75%
	Expected term years		4.7	5
	The volatility rate of grants is derived from historical Company common stock price volatility over the same time period as the expected term of each stock option award.  The volatility rate is derived by mathematical formula utilizing the weekly high closing stock price data over the expected term.
	The expected dividend yield is calculated using the Company's average of the last four quarterly dividend yields.
	The average risk-free interest rate is derived from United States Department of Treasury published interest rates of daily yield curves for the same time period as the expected term.
	GAAP specifies only share-based awards expected to vest be included in share-based compensation expense.  Estimated forfeiture rates are determined using historical forfeiture experience for each type of award and are excluded from the quantity of awards included in share-based compensation expense.
	The weighted average expected term reflects the analysis of historical share-based award transactions and includes option swap and reload grants which may have much shorter remaining expected terms than new option grants.
	A summary of the activity of the Company's stock option awards for 2014, 2013, and 2012 is presented below:
		2014					2013					2012

	Available for grant at end of year	7,271,093					8,454,854					9,808,610
	The following table provides the remaining contractual term and weighted average exercise prices of stock options outstanding and exercisable at December 31, 2014:
			Options Outstanding				Options Exercisable
	Range of Exercise Prices		Number  Outstanding at	Weighted-Average Remaining Contractual Life (Years)		Weighted-Average Exercise Price	Number Exercisable at		Weighted-Average Exercise Price

			2,209,800	6		$46	1,726,800		$37
	The range of exercise prices of options outstanding at December 31, 2014 is approximately $18 to $87 per share.  The aggregate intrinsic value of total options outstanding and total options exercisable at December 31, 2014 is $69 million and $68 million, respectively.  Intrinsic value is the amount by which the closing market price of the stock at December 31, 2014 exceeds the exercise price of the option grants.
	The weighted average remaining contractual life of all exercisable options at December 31, 2014 is 5.2 years.
	The weighted average fair value of options granted during 2014 and 2013 was $17.12 and $17.92, respectively.  There were no options granted in 2012. The total intrinsic value of options exercised during the years ended December 31, 2014, 2013, and 2012, was $22 million, $21 million, and $43 million, respectively.  Cash proceeds received by the Company from option exercises and the related tax benefit totaled $13 million and $7 million, respectively, for 2014, $12 million and $6 million, respectively, for 2013, and $40 million and $14 million, respectively, for 2012.  The total fair value of shares vested during the years ended December 31, 2014, 2013, and 2012 was $4 million, $3 million, and $5 million, respectively.
	A summary of the status of the Company's nonvested options as of December 31, 2014 and changes during the year then ended is presented below:
	Nonvested Options		Number of Options	Weighted-Average Grant Date Fair Value
	Nonvested at January 1, 2014		497,100	$14.80
	Granted		272,100	17.12
	Vested		-284,100	12.49
	Forfeited		-2,100	13.94
	Nonvested options at December 31, 2014		483,000	$17.47
	For nonvested options at December 31, 2014, approximately $3 million in compensation expense will be recognized over the next three years.
	Other Share-Based Compensation Awards
	In addition to stock option awards, the Company has awarded long-term performance share awards, restricted stock awards, and SARs.  The long-term performance 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-rata over the three year performance period. The number of long-term performance award target shares granted for the 2014-2016, 2013-2015, and 2012-2014 periods were 285 thousand, 270 thousand, and 338 thousand, respectively. The target shares granted 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 granted based on the award notice. The number of restricted stock awards granted during 2014, 2013, and 2012 were 144 thousand, 146 thousand, and 84 thousand, respectively. The fair value of a restricted stock award is equal to the closing stock price of the Company's stock on the date of grant and normally vests over a period of three years.  The recognized compensation expense before tax for these other share-based awards in the years ended December 31, 2014, 2013, and 2012 was approximately $24 million, $35 million, and $26 million, respectively.  The unrecognized compensation expense before tax for these same type awards at December 31, 2014 was approximately $35 million and will be recognized primarily over a period of two years.

	In the AFP segment, the Company manufactures chemicals for products in the coatings and tire industries in transportation, building and construction, durable goods, and consumables markets. This segment also contains the recently acquired Taminco specialty amines and crop protection businesses which primarily serve the personal care and agriculture markets. The products Eastman manufactures for the coatings industry can be broadly classified as solvents, which include specialty coalescents and ketones and esters, glycol ethers, and alcohol solvents; and polymers, which include cellulose and polyester-based specialty polymers and paint additives. Products for the tires industry are classified into three main product groups: insoluble sulfur products, which are vulcanizing agents principally marketed under the Crystex® brand; antidegradants, principally marketed under the Santoflex® brand; and hydrocarbon resins. The specialty amines business includes product lines that consist of specialty intermediates, performance products, and formic acid. The crop protection business consists of alkylamine derivatives product lines. Coatings industry and other formulated products sales accounted for 66 percent, 66 percent, and 80 percent of the AFP segment's total sales for 2014, 2013, and 2012 respectively. Tires industry sales accounted for 31 percent, 34 percent and 20 percent of the AFP segment's total sales for 2014, 2013 and 2012, respectively. The recently acquired specialty amines and crop protection businesses are included in December 2014 sales revenue and account for approximately 3 percent of total sales in 2014.
	In the A&P segment, the Company manufactures adhesives resins and plasticizers which are used in the manufacture of products sold into the consumables, building and construction, health and wellness, industrial chemicals and processing, and durable goods markets. The adhesives resins product line consists of hydrocarbon resins such as Regalite™ and Eastotac™; non-hydrogenated hydrocarbons resins such as Piccotac™; and rosins such as Eastoflex™. The plasticizers product line consists of a unique set of primary non-phthalate plasticizers such as Eastman 168™, and a range of niche non-phthalate plasticizers such as Benzoflex™ and Eastman TXIB™. Adhesives resins accounted for 53 percent, 52 percent, and 55 percent of the A&P segment's total sales for 2014, 2013, and 2012, respectively. Plasticizers accounted for 47 percent, 48 percent, and 45 percent of the A&P segment's total sales for 2014, 2013, and 2012, respectively.
	In the AM segment, the Company produces and markets specialty copolyesters, cellulose esters, interlayers, and aftermarket window film products that possess differentiated performance properties for value-added end uses in transportation, consumables, building and construction, durable goods, and health and wellness products. The specialty plastics product line consists of two primary products: specialty copolyesters and cellulose esters. The interlayers product line includes specialty intermediate polyvinyl butyral ("PVB") sheet and resins. PVB is a specialty resin used in the production of laminated safety glass sheet used in automotive and architectural applications. The performance films product line primarily consists of window film products, which are aftermarket applied films to enhance the characteristics and functional performance of automotive and architectural glass. Eastman's specialty plastics product line accounted for 54 percent, 53 percent, and 69 percent of the AM segment's total sales for 2014, 2013, and 2012, respectively. The interlayers product line accounted for 34 percent, 34 percent, and 23 percent of the AM segment's total sales for 2014, 2013, and 2012, respectively. The performance films product line accounted for 12 percent, 13 percent, and 8 percent of the AM segment's total sales for 2014, 2013, and 2012, respectively. The performance films product line includes the recently acquired Commonwealth in December 2014 total sales.
	In the Fibers segment, the Company manufactures Estron™ acetate tow and Estrobond™ triacetin plasticizers for use primarily in manufacture of cigarette filters; Estron™ natural (undyed) and Chromspun™ solution-dyed acetate yarns for use in apparel, home furnishings, and industrial fabrics; and cellulose acetate flake and acetyl raw materials for other acetate fiber producers. Acetate tow accounted for 79 percent, 83 percent, and 86 percent of the Fibers segment total sales revenue in 2014, 2013, and 2012, respectively, with the remainder of sales from other product lines, including acetate yarn and acetyl chemical products.
	In the SFI segment, the Company leverages large scale and vertical integration from the acetyl and olefins streams and the recently acquired alkylamine stream and proprietary manufacturing technology for specialty fluids to manufacture diversified products that are sold externally for use in markets such as industrial chemicals and processing, building and construction, health and wellness, and agrochemical; and that are used internally by other segments of the Company. In the chemical intermediates product line, the Company produces oxo alcohols and derivatives, acetic acid and derivatives and acetic anhydride. In the other intermediate product line, the Company produces olefin, chemical intermediates, and polymer intermediates. In the specialty fluids product line, the Company produces Therminol® heat transfer fluids and Skydrol® brand aviation hydraulic fluids. The recently acquired functional amines product lines include methylamines and salts, and higher amines and solvents. Chemical intermediates accounted for 50 percent, 48 percent, and 51 percent of the SFI segment's total sales for 2014, 2013, and 2012, respectively. Sales for other intermediate products accounted for 35 percent, 39 percent, and 42 percent of the SFI segment's total sales for 2014, 2013, and 2012, respectively. Specialty fluids accounted for 14 percent, 13 percent, and 7 percent of the SFI segment's total sales for 2014, 2013, and 2012, respectively. The recently acquired functional amines business is included in December 2014 sales revenue and accounts for approximately 1 percent of total sales in 2014.
	The Company continues to explore and invest in R&D initiatives that are aligned with macro trends in sustainability, consumerism, and energy efficiency such as high performance materials, advanced cellulosics, and reduced environmental impact. An example of such an initiative is the Eastman™ microfiber technology platform which leverages the Company's core competency in polymers chemistry, spinning capability, and in-house application expertise, for use in high purity air filtration, liquid filtration, and energy storage media, with opportunities for future growth in nonwoven and textile applications. The acquisition of Knowlton Technologies is expected to accelerate the Eastman™ microfiber technology platform innovation.
	Sales revenue and expense for the Eastman™ microfiber technology platform growth initiative are shown in the tables below as "other" sales revenue and operating loss. R&D, pension and other postretirement benefits, and other expenses and income not identifiable to an operating segment are shown in the tables below as "other" operating earnings (loss).
	Included in 2014 "other" was sales revenue from the acquired Knowlton business, part of the Eastman™ microfibers technology platform. Included in 2013 and 2012 "other" sales revenue were the Perennial Wood™ growth initiative and the Photovoltaics product line acquired from Solutia in 2012. There was no sales revenue related to Perennial Wood™ included in 2014 as a result of decisions made by management in 2013 not to continue its Perennial Wood™ growth initiative.

Description Of New Accounting Pronouncements Not Yet Adopted [Abstract]
RECENTLY ISSUED ACCOUNTING STANDARDS	RECENTLY ISSUED ACCOUNTING STANDARDS
	In April 2014, the Financial Accounting Standards Board ("FASB") issued amended accounting guidance for discontinued operations. The amendments improve the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on any entity's operations and financial results. Examples of a strategic shift that has (or will have) a major effect on an entity's operations and financial results could include a disposal of a major geographical area, a major line of business, a major equity method investment, or other major parts of an entity. The amendments require an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the assets and liability sections, respectively, of the statement of financial position. In addition to enhanced disclosures for discontinued operations, disclosures are required for disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation in the financial statements. This guidance is effective prospectively for reporting periods beginning on or after December 15, 2014. Early adoption is permitted, but only for disposals that have not been reported in financial statements previously issued or available for issuance. The Company has concluded that changes in its accounting required by this new guidance will not materially impact the Company's future accounting for any discontinued operations or its financial position or results of operations.
	In May 2014, the 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 this new guidance is expected to have on the Company's financial position or results of operations and related disclosures.

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Financial Statement Presentation	Financial Statement Presentation
	The consolidated financial statements of Eastman and subsidiaries are prepared in conformity with accounting principles generally accepted ("GAAP") in the United States and of necessity include some amounts that are based upon management estimates and judgments.  Future actual results could differ from such current estimates.  The 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 in minority-owned companies 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 Consolidated Financial Statements and accompanying footnotes to conform to current period presentation.
	Information related to the Commonwealth Laminating and Coating, Inc., ("Commonwealth") acquisition completed on December 11, 2014, the Taminco Corporation ("Taminco") acquisition completed on December 5, 2014, the Knowlton Technologies, LLC ("Knowlton") acquisition completed on August 6, 2014, the BP plc Global Aviation Turbine Engine Oil Business ("aviation turbine oil business") acquisition completed on June 2, 2014, and the Solutia, Inc. ("Solutia") acquisition completed on July 2, 2012 is in Note 2, "Acquisitions".  As of the date of acquisition, results of the acquired businesses are included in Eastman results.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include cash, time deposits, and readily marketable securities with original maturities of three months or less.
Fair Value Measurements	Fair Value Measurements
	The Company records recurring and non-recurring financial assets and liabilities as well as all non-financial assets and liabilities subject to fair value measurement at the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  These fair value principles prioritize valuation inputs across three broad levels.  Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.  Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.  Level 3 inputs are unobservable inputs based on the Company's assumptions used to measure assets and liabilities at fair value.  An asset or liability's classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments.  The allowances are based on the number of days an individual receivable is delinquent and management's regular assessment of the financial condition of the Company's customers.  The Company considers a receivable delinquent if it is unpaid after the terms of the related invoice have expired.  The Company evaluates the allowance based on a monthly assessment of the aged receivables.  Write-offs are recorded at the time a customer receivable is deemed uncollectible.  Allowance for doubtful accounts was $10 million and $12 million at December 31, 2014 and 2013, respectively.  The Company does not enter into receivables of a long-term nature, also known as financing receivables, in the normal course of business.
	The Company assumed the rights and obligations under non-recourse factoring facilities as part of the acquisition of Taminco. The non-recourse factoring facilities have a combined limit of $192 million (the U.S. Dollar equivalent of the €158 million commitment amount as of December 31, 2014) 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 eligible receivables sold and derecognized since the acquisition of Taminco on December 5, 2014 through December 31, 2014 was $61 million. The amounts outstanding under the non-recourse factoring facilities were $105 million at December 31, 2014. As part of the program, the Company continues to service the receivables at market rates with no servicing assets or liabilities recorded. 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 up to 5 percent on sold receivables.
Inventories	Inventories
	Inventories are valued at the lower of cost or market.  The Company determines the cost of most raw materials, work in process, and finished goods inventories in the United States by the last-in, first-out ("LIFO") method.  The cost of all other inventories, including inventories outside the United States, is determined by the average cost method, which approximates the first-in, first-out ("FIFO") method.  The Company writes-down its inventories for estimated obsolescence or unmarketable inventory equal to the difference between the carrying value of inventory and the estimated market value based upon assumptions about future demand and market conditions.
Properties and Depreciation	Properties
	The Company records properties at cost.  Maintenance and repairs are charged to earnings; replacements and betterments are capitalized.  When Eastman retires or otherwise disposes of assets, it removes the cost of such assets and related accumulated depreciation from the accounts.  The Company records any profit or loss on retirement or other disposition into earnings.  Asset impairments are reflected as increases in accumulated depreciation for properties that have been placed in service.  In instances when an asset has not been placed in service and is impaired, the associated costs are removed from the appropriate property accounts.
Depreciation, Depletion, and Amortization	Depreciation and Amortization
	Depreciation expense is calculated based on historical cost and the estimated useful lives of the assets, generally using the straight-line method.  Estimated useful lives for buildings and building equipment generally range from 20 to 50 years. Estimated useful lives generally ranging from 3 to 33 years are applied to machinery and equipment in the following categories: computer software (3 to 5 years); office furniture and fixtures and computer equipment (5 to 10 years); vehicles, railcars, and general machinery and equipment (5 to 20 years); and manufacturing-related improvements (20 to 33 years). Accelerated depreciation is reported when the estimated useful life is shortened and continues to be reported in Cost of Sales.
	Amortization expense for definite-lived intangible assets is generally determined using a straight-line method over the estimated useful life of the asset.

	Capitalized software costs are amortized primarily on a straight-line basis over three years, the expected useful life of such assets, beginning when the software project is substantially complete and placed in service.  Capitalized software in 2014, 2013, and 2012 was approximately $3 million, $5 million, and $5 million, respectively, and consisted of costs to internally develop computer software used by the Company.  During each of those same periods, approximately $7 million of previously capitalized costs were amortized.  At December 31, 2014 and 2013, unamortized capitalized software costs were $11 million and $14 million, respectively.  Capitalized software costs are reflected in other noncurrent assets.
Impairment of Long Lived Assets	Impairment of Long-Lived Assets
	Definite-lived Assets
	Properties and equipment and definite-lived intangible assets to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  The review of these long-lived assets is performed at the asset group level, which is the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If the carrying amount is not considered to be recoverable, an analysis of fair value is triggered.  An impairment is recorded for the excess of the carrying amount of the asset over the fair value. Fair value is either salvage value determined through market analysis or alternative future use.
	As the Company's assumptions related to long-lived assets are subject to change, write-downs may be required in the future. If estimates of fair value less costs to sell are revised, the carrying amount of the related asset is adjusted, resulting in a charge to earnings.
Goodwill and Intangible Assets, Policy	Goodwill
	The Company conducts testing of goodwill annually in third quarter of each year or when impairment indicators arise, whichever comes first. The testing of goodwill is performed at the "reporting unit" level which the Company has determined to be its "components". Components are defined as one level below an operating segment, and in order to be a reporting unit, the component must 1) be a "business" as defined by applicable accounting standards (an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to the investors or other owners, member, or participants); 2) have discrete financial information available; and 3) be reviewed regularly by Company operating segment management. The Company aggregates certain components into reporting units based on economic similarities. During 2014 testing, the Company did not evaluate the components acquired from Solutia in 2012 for aggregation, instead testing each component as a separate reporting unit. However, management will continue to review further aggregation during the next annual testing process as those components have now been integrated into Eastman.
	The Company uses an income approach and applies a fair value methodology based on discounted cash flows in testing the carrying value of goodwill for each reporting unit. The key assumptions and estimates used in the Company's 2014 goodwill impairment testing included a long-term projection of revenues, expenses, and cash flows, the estimated discount rate, and the estimated tax rate. The Company believes these assumptions are consistent with those a hypothetical market participant would use given circumstances that were present at the time the estimates were made. However, actual results and amounts may be significantly different from the Company's estimates. In addition, the use of different estimates or assumptions could result in materially different determinations. If the estimated fair value of a reporting unit is determined to be less than the carrying value of the net assets of the reporting unit including goodwill, additional steps, including an allocation of the estimated fair value to the assets and liabilities of the reporting unit, would be necessary to determine the amount, if any, of goodwill impairment.
	Indefinite-lived Intangible Assets
	The Company conducts testing of indefinite-lived intangible assets annually in third quarter of each year or when impairment indicators arise, whichever comes first. The carrying value of indefinite-lived intangible assets is considered to be impaired when the fair value, as established by appraisal or based on discounted future cash flows of certain related products, is less than the respective carrying values.
	Indefinite-lived intangible assets, consisting of various tradenames, are tested for potential impairment by comparing the estimated fair value to the carrying amount. The Company uses an income approach, specifically the relief from royalty method, to test indefinite-lived intangible assets. The estimated fair value of the tradenames is determined based on an assumed royalty rate savings, discounted by the calculated market participant weighted average cost of capital plus a one percent risk premium. The carrying value of indefinite-lived intangible assets is considered to be impaired when the estimated fair value is less than the carrying value of the trademarks.
Investments	Investments
	The consolidated financial statements include the accounts of the Company and all its subsidiaries and entities/joint ventures in which a controlling interest is maintained.
	Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis.  Under the equity method of accounting, these investments are included in other noncurrent assets.  The Company includes its share of earnings and losses of such investments in other (income) charges, net, and its share of other comprehensive income (loss) in the appropriate component of accumulated other comprehensive income (loss) in stockholders' equity.
Pension and Other Post-employment Benefits	Pension and Other Postretirement Benefits
	The Company maintains defined benefit pension plans that provide eligible employees with retirement benefits.  Additionally, Eastman provides a subsidy toward life insurance, health care, and dental benefits for eligible retirees and a subsidy toward health care and dental benefits for retirees' eligible survivors.  The costs and obligations related to these benefits reflect the Company's assumptions related to general economic conditions (particularly interest rates), expected return on plan assets, rate of compensation increase or decrease for employees, and health care cost trends.  The cost of providing plan benefits depends on demographic assumptions including retirements, mortality, turnover, and plan participation.
	Eastman's pension and other postretirement benefit plans costs consist of two elements: 1) ongoing costs recognized quarterly, which are comprised of service and interest costs, expected returns on plan assets, and amortization of prior service credits; and 2) mark-to-market ("MTM") gains and losses recognized annually, in the fourth quarter of each year, resulting from changes in actuarial assumptions for discount rates and the differences between actual and expected returns on plan assets. Any interim remeasurements triggered by a curtailment, settlement, or significant plan changes are recognized as an MTM adjustment in the quarter in which such remeasurement event occurs.
	For additional information, see Note 11, "Retirement Plans".
Environmental Costs	Environmental Costs
	The Company accrues environmental remediation costs when it is probable that the Company has incurred a liability at a contaminated site and the amount can be reasonably estimated.  When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount.  This undiscounted accrued amount reflects liabilities expected to be paid out within 30 years and the Company's assumptions about remediation requirements at the contaminated site, the nature of the remedy, the outcome of discussions with regulatory agencies and other potentially responsible parties at multi-party sites, and the number and financial viability of other potentially responsible parties.  Changes in the estimates on which the accruals are based, unanticipated government enforcement action, or changes in health, safety, environmental, and chemical control regulations and testing requirements could result in higher or lower costs.
	The Company also establishes reserves for closure/postclosure costs associated with the environmental and other assets it maintains.  Environmental assets include but are not limited to waste management units, such as landfills, water treatment facilities, and surface impoundments.  When these types of assets are constructed or installed, a reserve is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets and the applicable regulatory closure requirements.  These expenses are charged into earnings over the estimated useful life of the assets.  Currently, the Company estimates the useful life of each individual asset up to 50 years.  If the Company changes its estimate of the environmental asset retirement obligation costs or its estimate of the useful lives of these assets, the expenses charged into earnings could increase or decrease.  The Company also monitors conditional obligations and recognizes contingent liabilities associated with them when and to the extent that more detailed information becomes available concerning applicable retirement costs.
	The current portion of accruals for environmental liabilities is included in payables and other current liabilities with the long-term portion included in other long-term liabilities. These accruals exclude claims for recoveries from insurance companies or other third parties.  Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination.  The cost of operating and maintaining environmental control facilities is charged to expense.
	For additional information see Note 13, "Environmental Matters and Asset Retirement Obligations".
Derivative Financial Instruments	Derivative Financial Instruments
	Derivative financial instruments are used by the Company when appropriate to manage its exposures to fluctuations in foreign currency exchange rates, certain contract sales prices, raw material and energy costs, and interest rates.  These instruments are used to mitigate the risk that changes in exchange rates, sales prices, raw material and energy costs, or interest rates will adversely affect the eventual dollar cash flows resulting from the hedged transactions.
	From time to time, the Company enters into currency option and forward contracts to hedge anticipated, but not yet committed, export sales and purchase transactions expected within no more than five years and denominated in foreign currencies (principally the euro and the Japanese yen); and forward exchange contracts to hedge certain firm commitments denominated in foreign currencies.  To mitigate fluctuations in the market prices of commodities and their effects on the cash costs of the underlying transactions expected over the next five years for propane, ethane, natural gas, paraxylene, and benzene (certain raw material and energy used in the manufacturing process) and selling prices for ethylene, the Company may enter into option and forward contracts.  From time to time, the Company also utilizes interest rate derivative instruments, primarily forward starting interest rate swaps and Treasury locks, to hedge the Company's exposure to movements in interest rates.
	The Company's qualifying option and forward contracts are accounted for as hedges because the derivative instruments are designated and demonstrated to be effective as hedges of the underlying risks.  Gains and losses resulting from effective hedges of existing liabilities, firm commitments, or anticipated transactions are deferred and recognized when the offsetting gains and losses are recognized on the related hedged items and are reported as a component of operating earnings.  Derivative assets and liabilities are recorded at fair value.
	The gains or losses on nonqualifying derivatives or derivatives that are not designated as hedges are marked to market and immediately recorded into earnings from continuing operations.
	Deferred option premiums are included in the fair market value of the hedges.  The related obligation for payment is generally included in other liabilities and is paid in the period in which the options are exercised or expire.
	For additional information see Note 10, "Derivatives".
Litigation and Contingent Liabilities	Litigation and Contingent Liabilities
	The Company and its operations from time to time are, and in the future may be, parties to or targets of lawsuits, claims, investigations, and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which are handled and defended in the ordinary course of business.  The Company accrues a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated.  When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount.  The Company expenses legal costs, including those expected to be incurred in connection with a loss contingency, as incurred.
Revenue Recognition and Customer Incentives	Revenue Recognition and Customer Incentives
	The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the customer is fixed or determinable, and collectability is reasonably assured.  Revenue for products is recognized when title and risk of loss transfer to the customer.
	The Company records estimated obligations for customer programs and incentive offerings, which consist primarily of revenue or volume-based amounts that a customer must achieve over a specified period of time, as a reduction of revenue from each underlying revenue transaction as the customer progresses toward goals specified in incentive agreements.  These estimates are based on a combination of forecasts of customer sales and actual sales volume and revenues against established goals, the customer's current level of purchases, Eastman's knowledge of customer purchasing habits, and industry pricing practice.  The incentive payment rate may be variable, based upon the customer reaching higher sales volume or revenue levels over a specified period of time in order to receive an agreed upon incentive payment.
Shipping and Handling Fees and Costs	Shipping and Handling Fees and Costs
	Shipping and handling fees related to sales transactions are billed to customers and are recorded as sales revenue.  Shipping and handling costs incurred are recorded in cost of sales.
Restructuring of Operations	Restructuring of Operations
	The Company records restructuring charges incurred in connection with consolidation of operations, exited business or product lines, or shutdowns of specific sites that are expected to be substantially completed within twelve months.  These restructuring charges are recorded as incurred, and are associated with site closures, legal and environmental matters, demolition, contract terminations, obsolete inventory, or other costs directly related to the restructuring.  The Company records severance charges for employee separations when the separation is probable and reasonably estimable.  In the event employees are required to perform future service, the Company records severance charges ratably over the remaining service period of those employees.
Share-based Compensation	Share-based Compensation
	The Company recognizes compensation expense in the financial statements for stock options and other share-based compensation awards based upon the grant-date fair value over the substantive vesting period.
	For additional information, see Note 18, "Share-Based Compensation Plans and Awards".
Research and Development	Research and Development
	All costs identified as research and development ("R&D") costs are charged to expense when incurred with the exception of third-party reimbursed and government-funded R&D.  Expenses for third-party reimbursed and government-funded R&D are deferred until reimbursement is received to ensure appropriate matching of revenue and expense, provided specific criteria are met.
Income Taxes	Income Taxes
	The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes.  Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid.  The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year.  Deferred taxes result from differences between the financial and tax bases of the Company's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted.  Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.  Provision has been made for income taxes on unremitted earnings of subsidiaries and affiliates, except for subsidiaries in which earnings are deemed to be indefinitely reinvested.
	The Company recognizes income tax positions that meet the more likely than not threshold and accrues interest related to unrecognized income tax positions which is recorded as a component of the income tax provision.
Purchase Accounting	Purchase Accounting
	In general, the acquisition method of accounting requires recognition of assets acquired and liabilities assumed at their respective fair values at the date of acquisition. For assets and liabilities other than intangible assets and property, plant, and equipment, the Company estimates fair value using the exit price approach which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly market. An exit price is determined from the viewpoint of unrelated market participants as a whole, in the principal or most advantageous market, and may result in the Company valuing assets or liabilities at a fair value that is not reflective of the Company's intended use of the assets or liabilities. Any amount of the purchase price paid that is in excess of the estimated fair values of net assets acquired or liabilities assumed is recorded in the line item goodwill on the Company's consolidated balance sheets.
	For intangible assets, the Company uses the income, market, or cost approach (or a combination thereof) for the valuation as appropriate, and uses valuation inputs in these models and analyses that are based on market participant assumptions. Management values property, plant and equipment using the cost approach supported where available by observable market data which includes consideration of obsolescence. See Note 2, "Acquisitions". Management's judgment is used to determine the estimated fair values assigned to assets acquired and liabilities assumed, as well as asset lives for property, plant and equipment and amortization periods for intangible assets, and can materially affect the Company's results of operations.
