Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	The company follows generally accepted accounting principles in the United States of America (GAAP). The significant accounting policies described below, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.
	Preparation of Financial Statements
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Basis of Consolidation
	The Consolidated Financial Statements include the accounts of the company, subsidiaries in which a controlling interest is maintained and variable interest entities (VIEs) for which DuPont is the primary beneficiary. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has significant influence but not a controlling interest are carried on the equity method. At December 31, 2014, the assets, liabilities and operations of VIEs for which DuPont is the primary beneficiary were not material to the Consolidated Financial Statements of the company.
	The company is also involved with certain joint ventures accounted for under the equity method of accounting that are VIEs. The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2014, the maximum exposure to loss related to the unconsolidated VIEs is not considered material to the Consolidated Financial Statements of the company.
	Basis of Presentation
	Certain reclassifications of prior year's data have been made to conform to current year's presentation.
	The company’s cost structure has been impacted by the global, multi-year initiative to redesign its global organization and operating model to improve productivity and agility across all businesses and functions. Effective December 31, 2014, in order to better align to the transforming company’s organization and resulting cost structure, certain costs were reclassified from other operating charges to selling, general and administrative expenses. Prior year data has been reclassified to conform to current year presentation.
	In November 2013, DuPont entered into a definitive agreement to sell Glass Laminating Solutions/Vinyls (GLS/Vinyls), a part of the Performance Materials segment. The assets related to GLS/Vinyls at December 31, 2013 are presented as held for sale in the Consolidated Balance Sheet. In June 2014, the company sold GLS/Vinyls to Kuraray Co. Ltd. The sale of GLS/Vinyls does not meet the criteria for discontinued operations and as such, earnings are included in the company’s income from continuing operations.
	In February 2013, the company sold its Performance Coatings business (which represented a reportable segment). In accordance with GAAP, the results of Performance Coatings are presented as discontinued operations and, as such, have been excluded from continuing operations and segment results for all periods presented. The sum of the individual earnings per share amounts from continuing and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to Performance Coatings have not been segregated and are included in the Consolidated Statements of Cash Flows and Comprehensive Income, respectively, for all periods presented. Amounts related to Performance Coatings are consistently included in or excluded from the Notes to the Consolidated Financial Statements based on the financial statement line item and period of each disclosure.
	See Note 2 to the Consolidated Financial Statements for further information relating to the above matters.
	Revenue Recognition
	The company recognizes revenue when the earnings process is complete. The company's revenues are from the sale of a wide range of products to a diversified base of customers around the world. Revenue for product sales is recognized upon delivery, when title and risk of loss have been transferred, collectability is reasonably assured and pricing is fixed or determinable. A majority of product sales are sold FOB (free on board) shipping point or, with respect to non United States of America (U.S.) customers, an equivalent basis. Accruals are made for sales returns and other allowances based on the company's experience. The company accounts for cash sales incentives as a reduction in sales and noncash sales incentives as a charge to cost of goods sold or selling expense, depending on the nature of the incentive. Amounts billed to customers for shipping and handling fees are included in net sales and costs incurred by the company for the delivery of goods are classified as cost of goods sold in the Consolidated Income Statements. Taxes on revenue-producing transactions are excluded from net sales.
	The company periodically enters into prepayment contracts with customers in the Agriculture segment and receives advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue (classified as other accrued liabilities) or debt, depending on the nature of the program. Revenue associated with advance payments is recognized as shipments are made and title, ownership and risk of loss pass to the customer.
	Licensing and royalty income is recognized in accordance with agreed upon terms, when performance obligations are satisfied, the amount is fixed or determinable and collectability is reasonably assured.
	Cash and Cash Equivalents
	Cash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest. The estimated fair value of the company's cash equivalents, which approximates carrying value as of December 31, 2014 and 2013, was determined using level 1 and level 2 inputs within the fair value hierarchy, as described below. Level 1 measurements were based on observed net asset values and level 2 measurements were based on current interest rates for similar investments with comparable credit risk and time to maturity. The company held $1,436 and $5,116 of money market funds (level 1 measurements) as of December 31, 2014 and 2013, respectively.  The company held $3,293 and $2,256 of other cash equivalents (level 2 measurements) as of December 31, 2014 and 2013, respectively.
	Marketable Securities
	Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. They are classified as held-to-maturity and recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments.
	Fair Value Measurements
	Under the accounting for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
	The company uses the following valuation techniques to measure fair value for its assets and liabilities:
	Level 1	–	Quoted market prices in active markets for identical assets or liabilities;
	Level 2	–	Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs);
	Level 3	–	Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.
	Inventories
	The company's inventories are valued at the lower of cost or market. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or market, whichever is lower; cost is generally determined by the average cost method.
	As of December 31, 2014 and 2013 approximately 50 percent, 25 percent and 25 percent of the company’s inventories were accounted for under the first-in first out (FIFO), last-in first out (LIFO) and average cost methods, respectively. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as seeds, certain food-ingredients and enzymes.
	Property, Plant and Equipment
	Property, plant and equipment is carried at cost and is depreciated using the straight-line method. Property, plant and equipment placed in service prior to 1995 is depreciated under the sum-of-the-years' digits method or other substantially similar methods. Substantially all equipment and buildings are depreciated over useful lives ranging from 15 to 25 years. Capitalizable costs associated with computer software for internal use are amortized on a straight-line basis over 5 to 7 years. When assets are surrendered, retired, sold or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the accounts and included in determining gain or loss on such disposals.
	Maintenance and repairs are charged to operations; replacements and improvements are capitalized.
	Goodwill and Other Intangible Assets
	Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. The company's fair value methodology is based on prices of similar assets or other valuation methodologies including discounted cash flow techniques. During the third quarter 2014, the company changed its annual impairment testing from September 30th to July 1st. The company believes this timing is preferable as it better aligns the goodwill impairment test with its strategic business planning cycle. This change did not result in the delay, acceleration or avoidance of an impairment charge. The change was applied prospectively, as retrospective application would have been impractical because the company is unable to objectively select assumptions that would have been used in previous periods without the benefit of hindsight. The company completed its annual impairment testing in the third quarter of 2014 and determined that no adjustments to the carrying value of goodwill or indefinite lived intangible assets were necessary.
	Definite-lived intangible assets, such as purchased and licensed technology, patents and customer lists are amortized over their estimated useful lives, generally for periods ranging from 1 to 20 years or amortized based on units of production. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the Consolidated Balance Sheets.
	Impairment of Long-Lived Assets
	The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from the assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. The company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of other than by sale are classified as held for use until their disposal. Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair market value less cost to sell. Depreciation is discontinued for long-lived assets classified as held for sale.
	Research and Development
	Research and development costs are expensed as incurred. Research and development expenses include costs (primarily consisting of employee costs, materials, contract services, research agreements, and other external spend) relating to the discovery and development of new products, enhancement of existing products and regulatory approval of new and existing products.
	Environmental
	Accruals for environmental matters are recorded in operating expenses when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Accrued liabilities do not include claims against third parties and are not discounted.
	Costs related to environmental remediation and restoration are charged to expense. Other environmental costs are also charged to expense unless they increase the value of the property or reduce or prevent contamination from future operations, in which case, they are capitalized.
	Asset Retirement Obligations
	The company records asset retirement obligations at fair value at the time the liability is incurred. Accretion expense is recognized as an operating expense using the credit-adjusted risk-free interest rate in effect when the liability was recognized. The associated asset retirement obligations are capitalized as part of the carrying amount of the long-lived asset and depreciated over the estimated remaining useful life of the asset, generally for periods ranging from 1 to 25 years.
	Litigation
	The company accrues for liabilities related to litigation matters when the information available indicates that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs such as outside counsel fees and expenses are charged to expense in the period incurred.
	Insurance/Self-Insurance
	The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable.
	Income Taxes
	The provision for income taxes is 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 basis 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 invested. Investment tax credits or grants are accounted for in the period earned (the flow-through method). Interest accrued related to unrecognized tax benefits is included in miscellaneous income and expenses, net, within other income, net. Income tax related penalties are included in the provision for income taxes.
	Foreign Currency Translation
	The company's worldwide operations utilize the U.S. dollar (USD) or local currency as the functional currency, where applicable. The company identifies its separate and distinct foreign entities and groups the foreign entities into two categories: 1) extension of the parent (USD functional currency) and 2) self-contained (local functional currency). If a foreign entity does not align with either category, factors are evaluated and a judgment is made to determine the functional currency.
	For foreign entities where the USD is the functional currency, all foreign currency asset and liability amounts are remeasured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.
	For foreign entities where the local currency is the functional currency, assets and liabilities denominated in local currencies are translated into USD at end-of-period exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the local currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during the period.
	The company changes the functional currency of its separate and distinct foreign entities only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed. As a result of the separation of its Performance Chemicals segment, coupled with the company’s redesign initiative, the functional currency at certain of the company’s foreign entities is being re-evaluated and, in some cases, will result in a change in the foreign entities’ functional currency during 2015. This re-evaluation will not impact the company's results of operations.
	Venezuelan Foreign Currency
	Venezuela is considered a highly inflationary economy under GAAP and the USD is the functional currency for the company's subsidiaries in Venezuela. During the first quarter 2014, the Venezuelan government enacted certain changes to the country’s foreign exchange systems including the expansion of the use of the Complementary System of Foreign Currency Acquirement (SICAD 1) auction rate and introduction of the SICAD 2 auction process. The official exchange rate continues to be set through the National Center for Foreign Commerce (CENCOEX, previously CADIVI) at 6.3 Bolivar Fuertes (BsF) to USD. Based on its evaluation of the restrictions and limitations affecting the availability of specific exchange rate mechanisms, management has concluded that the SICAD 2 auction process would be the most likely mechanism available. As a result, effective June 30, 2014, the company changed from the official exchange rate to the SICAD 2 exchange rate of 49.98, to remeasure its BsF denominated net monetary assets which resulted in a pre-tax charge of $58. The charge is recorded within other income, net in the company's Consolidated Income Statements for the year ended December 31, 2014. The company expects it will continue to use the SICAD 2 exchange rate to remeasure its Venezuelan BsF denominated revenues, expenses and net monetary assets unless facts and circumstances change.
	Hedging and Trading Activities
	Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. For derivative instruments designated as fair value hedges, changes in the fair values of the derivative instruments will generally be offset in the income statement by changes in the fair value of the hedged items. For derivative instruments designated as cash flow hedges, the effective portion of any hedge is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. The ineffective portion of all hedges is recognized in current period earnings. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings.
	In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, gains or losses realized at termination are deferred and included in the measurement of the hedged transaction. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as a hedge of an anticipated transaction are reclassified as for trading purposes if the anticipated transaction is no longer probable.
	Cash flows from derivative instruments accounted for as either fair value hedges or cash flow hedges are reported in the same category as the cash flows from the items being hedged. Cash flows from all other derivative instruments are generally reported as investing activities in the Consolidated Statements of Cash Flows. See Note 19 for additional discussion regarding the company's objectives and strategies for derivative instruments.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) and the International Accounting Standards Board (IASB) jointly issued Accounting Standards Update (ASU) No. 2014-9, Revenue from Contracts with Customers (Topic 606), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (IFRS). The core principle of the 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. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted under GAAP and retrospective application is permitted, but not required. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
In April 2014, the FASB issued authoritative guidance amending existing requirements for reporting discontinued operations.  Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. Public entities will apply the amended guidance prospectively to all disposals occurring within annual periods beginning on or after December 15, 2014 and interim periods within those years. The company will adopt this standard on January 1, 2015. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under current standards.

	Glass Laminating Solutions/Vinyls
	In June 2014, the company sold Glass Laminating Solutions/Vinyls (GLS/Vinyls), a part of the Performance Materials segment, to Kuraray Co. Ltd. The sale resulted in a pre-tax gain of $391 ($273 net of tax). The gain was recorded in other income, net in the company's Consolidated Income Statements for the year ended December 31, 2014.
	The assets classified as held for sale at December 31, 2013 related to GLS/Vinyls primarily consist of inventory and property, plant and equipment.
	Performance Chemicals
	On October 24, 2013, DuPont announced that it intends to separate its Performance Chemicals segment through a U.S. tax-free spin-off to shareholders, subject to customary closing conditions. The company expects to complete the separation about mid-2015. During the year ended December 31, 2014, the company incurred $175 of costs associated with the transaction which were reported in other operating charges in the company's Consolidated Income Statements.

Restructuring Charges [Abstract]
Employee Separation / Asset Related Charges, Net	EMPLOYEE SEPARATION/ASSET RELATED CHARGES, NET
	At December 31, 2014, total liabilities related to restructuring activities were $277, primarily related to the 2014 restructuring program.
	2014 Restructuring Program
	In June 2014, DuPont announced its global, multi-year initiative to redesign its global organization and operating model to reduce costs and improve productivity and agility across all businesses and functions. DuPont commenced a restructuring plan to realign and rebalance staff function support, enhance operational efficiency, and to reduce residual costs associated with the separation of its Performance Chemicals segment.  As a result, during the year ended December 31, 2014 a pre-tax charge of $562 was recorded, consisting of $497 in employee separation / asset related charges, net and $65 in other income, net. The charges consisted of $319 of employee separation charges, $17 of other non-personnel charges, and $226 of asset related charges, including $65 of charges associated with the restructuring actions of a joint venture within the Performance Materials segment. At December 31, 2014, total liabilities related to the 2014 restructuring program were $268. The actions associated with this charge and all related payments are expected to be substantially complete by mid-2016. The company anticipates that it will incur future charges, which it cannot reasonably estimate at this time, related to this plan as it implements additional actions.
	The 2014 restructuring program charges impacted segment earnings, as follows, for the year ended December 31, 2014: Agriculture - $134, Electronics & Communications - $84, Industrial Biosciences - $13, Nutrition & Health - $15, Performance Chemicals - $21, Performance Materials - $99, and Safety & Protection - $52, Other - $22, as well as Corporate expenses - $122.
	Account balances and activity for the 2014 restructuring program are summarized below:
		Employee Separation Costs			Asset			Other Non-Personnel Charges1			Total

	1.	Other non-personnel charges consist of contractual obligation costs.
	2012 Restructuring Program
	In 2012, the company commenced a restructuring plan to increase productivity, enhance competitiveness and accelerate growth. As a result, pre-tax charges of $234 were recorded in employee separation / asset related charges, net. The 2012 charges consisted of $157 of employee separation costs, $8 of other non-personnel charges, and $69 of asset related charges, which included $30 of asset impairments and $39 of asset shut downs.
	In addition to the programs discussed above, a charge of $19, which included $9 recorded in employee separation / asset related charges, net and $10 recorded in other income, net, was taken in the fourth quarter 2013. This charge was a result of restructuring actions including employee separation and asset related costs related to a joint venture in the Performance Materials segment.
	The actions and payments related to the 2012 restructuring program were substantially complete as of December 31, 2013.
	Asset Impairments
	In the fourth quarter 2013, as a result of strategic decisions related to the thin film photovoltaic market, and during 2012, as a result of deteriorating conditions in the thin film photovoltaic market, the company determined that impairment triggering events had occurred and that assessments of the asset group related to its thin film photovoltaic modules and systems were warranted. These assessments determined that the carrying value of the asset group exceeded its fair value. As a result of the impairment tests, $129 and $150 of pre-tax impairment charges were recorded during 2013 and 2012, respectively, within the Electronics & Communications segment.
	During 2012, as a result of strategic decisions related to deteriorating conditions within a specific industrial chemicals market, the company determined that an impairment triggering event had occurred and that an assessment of the asset group related to this industrial chemical was warranted. This assessment determined that the carrying value of the asset group exceeded its fair value. As a result of the impairment test, a $33 pre-tax impairment charge was recorded within the Performance Chemicals segment.
	During 2012, as a result of deteriorating conditions in an industrial polymer market, the company determined that an impairment triggering event had occurred and that an assessment of the asset group related to this polymer product was warranted. This assessment determined that the carrying value of the asset group exceeded its fair value. As a result of the impairment test, a $92 pre-tax impairment charge was recorded within the Performance Materials segment.
	The bases of the fair value for the charges above were calculated utilizing a discounted cash flow approach which included assumptions concerning future operating performance and economic conditions that may differ from actual cash flows. In connection with the matters discussed above, as of December 31, 2013 and 2012, the company had long-lived assets with a remaining net book value of approximately $90 and $150, respectively, accounted for at fair value on a nonrecurring basis after initial recognition. These nonrecurring fair value measurements were determined using level 3 inputs within the fair value hierarchy, as described in Note 1 to the Consolidated Financial Statements.

	1.	The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on continuing operations on the Consolidated Income Statements. Exchange gains (losses) related to earnings of affiliates was $0, $4 and $3 for 2014, 2013 and 2012, respectively. The $135 net exchange gain for the year ended December 31, 2014, includes $(58), $(46) and $(14) exchange losses, associated with the devaluation of the Venezuelan bolivar, Ukrainian hryvnia, and Argentinian peso, respectively. The $(128) net exchange loss for the year ended December 31, 2013, includes a $(33) exchange loss, associated with the devaluation of the Venezuelan bolivar.

	1.	Principally reflects the impact of foreign exchange losses on net monetary assets for which no corresponding tax benefit is realized. Further information about the company's foreign currency hedging program is included in Note 19 under the heading Foreign Currency Risk.
	2.	On January 2, 2013, U.S. tax law was enacted which extended through 2013 (and retroactive to 2012) several expired or expiring temporary business tax provisions. In accordance with GAAP, this extension was taken into account in the quarter in which the legislation was enacted (i.e. first quarter 2013).
	Consolidated income from continuing operations before income taxes for U.S. and international operations was as follows:
		2014			2013			2012
	U.S. (including exports)	$	2,780		$	962		$	640
	International	2,211			2,527			2,448
	Income from continuing operations before income taxes	$	4,991		$	3,489		$	3,088
	The increased proportion of income from continuing operations before income taxes in the U.S over prior years is primarily due to the results of the company’s hedging program, gains on sales of businesses primarily in the U.S., and the impact of Imprelis® charges in the U.S. in 2013 versus additional insurance recoveries recorded in the U.S. in 2014.
	In 2014 and 2013, the U.S. recorded a net exchange gain associated with the hedging program of $607 and $35, respectively. While the taxation of the amounts reflected on the chart above does not correspond precisely to the jurisdiction of taxation (due to taxation in multiple countries, exchange gains/losses, etc.), it represents a reasonable approximation of the income before income taxes split between U.S. and international jurisdictions. See Note 19 for additional information regarding the company's hedging program.
	Under the tax laws of various jurisdictions in which the company operates, deductions or credits that cannot be fully utilized for tax purposes during the current year may be carried forward or back, subject to statutory limitations, to reduce taxable income or taxes payable in future or prior years. At December 31, 2014, the tax effect of such carryforwards/backs, net of valuation allowance approximated $1,080. Of this amount, $921 has no expiration date, $1 expires after 2014 but before the end of 2019 and $158 expires after 2019.
	At December 31, 2014, unremitted earnings of subsidiaries outside the U.S. totaling $17,226 were deemed to be indefinitely reinvested. No deferred tax liability has been recognized with regard to the remittance of such earnings. It is not practicable to estimate the income tax liability that might be incurred if such earnings were remitted to the U.S.
	Each year the company files hundreds of tax returns in the various national, state and local income taxing jurisdictions in which it operates. These tax returns are subject to examination and possible challenge by the tax authorities. Positions challenged by the tax authorities may be settled or appealed by the company. As a result, there is an uncertainty in income taxes recognized in the company's financial statements in accordance with accounting for income taxes and accounting for uncertainty in income taxes. It is reasonably possible that net reductions to the company’s global unrecognized tax benefits could be in the range of $100 to $125 within the next 12 months with the majority due to the settlement of uncertain tax positions with various tax authorities.
	The company and/or its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various states and non-U.S. jurisdictions. With few exceptions, the company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2004. A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:
		2014			2013			2012

	Weighted-average number of common shares outstanding – Diluted	921,873,000			933,147,000			942,197,000
	The weighted-average number of common shares outstanding in 2014 and 2013 decreased as a result of the company's repurchase and retirement of its common stock, partially offset by the issuance of new shares from the company's equity compensation plans(see Notes 16 and 18, respectively).
	The following average number of stock options are antidilutive and therefore, are not included in the diluted earnings per share calculation:
		2014		2013		2012
	Average number of stock options	3,000		2,596,000		12,158,000
	The change in the average number of stock options that were antidilutive in 2014 and 2013 was due to changes in the company's average stock price.

That estimate is based on historical collection experience, current economic and market conditions, and review of the current status of customers' accounts.
	2.	Notes receivable – trade primarily consists of receivables within the Agriculture segment for deferred payment loan programs for the sale of seed products to customers. These loans have terms of one year or less and are primarily concentrated in North America. The company maintains a rigid pre-approval process for extending credit to customers in order to manage overall risk and exposure associated with credit losses. As of December 31, 2014 and 2013, there were no significant past due notes receivable, nor were there any significant impairments related to current loan agreements.
	3.	Other includes receivables in relation to fair value of derivative instruments, value added tax, general sales tax and other taxes.
	Accounts and notes receivable are carried at amounts that approximate fair value.

	The estimated fair value of the company's short-term borrowings, including interest rate financial instruments, was determined using level 2 inputs within the fair value hierarchy, as described in Note 1 to the Consolidated Financial Statements. Based on quoted market prices for the same or similar issues, or on current rates offered to the company for debt of the same remaining maturities, the fair value of the company's short-term borrowings was $1,424 and $1,730 at December 31, 2014 and 2013, respectively.
	Unused bank credit lines were approximately $4,900 and $4,400 at December 31, 2014 and 2013, respectively. These lines are available to support short-term liquidity needs and general corporate purposes including letters of credit and have a remaining life of up to four years. Outstanding letters of credit were $349 and $352 at December 31, 2014 and 2013, respectively. These letters of credit support commitments made in the ordinary course of business.
	The weighted-average interest rate on short-term borrowings outstanding at December 31, 2014 and 2013 was 1.7% and 3.0%, respectively. The decrease in the interest rate for 2014 was primarily due to long-term debt maturing within one year.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES
	Guarantees
	Indemnifications
	In connection with acquisitions and divestitures, the company has indemnified respective parties against certain liabilities that may arise in connection with these transactions and business activities prior to the completion of the transaction. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. In addition, the company indemnifies its duly elected or appointed directors and officers to the fullest extent permitted by Delaware law, against liabilities incurred as a result of their activities for the company, such as adverse judgments relating to litigation matters. If the indemnified party were to incur a liability or have a liability increase as a result of a successful claim, pursuant to the terms of the indemnification, the company would be required to reimburse the indemnified party. The maximum amount of potential future payments is generally unlimited.
	Obligations for Equity Affiliates & Others
	The company has directly guaranteed various debt obligations under agreements with third parties related to equity affiliates, customers and suppliers. At December 31, 2014, the company had directly guaranteed $513 of such obligations. This amount represents the maximum potential amount of future (undiscounted) payments that the company could be required to make under the guarantees. The company would be required to perform on these guarantees in the event of default by the guaranteed party.
	The company assesses the payment/performance risk by assigning default rates based on the duration of the guarantees. These default rates are assigned based on the external credit rating of the counterparty or through internal credit analysis and historical default history for counterparties that do not have published credit ratings. For counterparties without an external rating or available credit history, a cumulative average default rate is used.
	In certain cases, the company has recourse to assets held as collateral, as well as personal guarantees from customers and suppliers. Assuming liquidation, these assets are estimated to cover approximately 35 percent of the $328 of guaranteed obligations of customers and suppliers. Set forth below are the company's guaranteed obligations at December 31, 2014:
		Short-Term		Long-Term		Total
	Obligations for customers and suppliers1:
	Bank borrowings (terms up to 7 years)	$	226	$	100	$	326
	Leases on equipment and facilities (terms up to 4 years)	—		2		2
	Obligations for equity affiliates2:
	Bank borrowings (terms up to 1 year)	185		—		185
	Total	$	411	$	102	$	513
	1	Existing guarantees for customers and suppliers, as part of contractual agreements.
	2	Existing guarantees for equity affiliates' liquidity needs in normal operations.
	Operating Leases
	The company uses various leased facilities and equipment in its operations. The terms for these leased assets vary depending on the lease agreement.
	Future minimum lease payments (including residual value guarantee amounts) under non-cancelable operating leases are $303, $280, $255, $230 and $193 for the years 2015, 2016, 2017, 2018 and 2019, respectively, and $353 for subsequent years and are not reduced by non-cancelable minimum sublease rentals due in the future in the amount of $1. Net rental expense under operating leases was $324, $303 and $316 in 2014, 2013 and 2012, respectively.
	Asset Retirement Obligations
	The company has recorded asset retirement obligations primarily associated with closure, reclamation and removal costs for mining operations related to the production of titanium dioxide in Performance Chemicals. The company's asset retirement obligation liabilities were $52 and $63 at December 31, 2014 and 2013.
	Imprelis®
	The company has received claims and has been served with multiple lawsuits alleging that the use of Imprelis® herbicide caused damage to certain trees. Sales of Imprelis® were suspended in August 2011 and the product was last applied during the 2011 spring application season. The lawsuits seeking class action status were consolidated in multidistrict litigation in federal court in Philadelphia, Pennsylvania. In February 2014, the court entered the final order dismissing these lawsuits as a result of the class action settlement.
	As part of the settlement, DuPont paid about $7 in plaintiffs' attorney fees and expenses. In addition, DuPont is providing a warranty against new damage, if any, caused by the use of Imprelis® on class members' properties through May 2015. Certain class members opted out of the class action settlement and made independent claims or filed suit in various state courts, the majority of which were removed to federal court in Philadelphia. In the third quarter 2014, the company settled or reached settlements in principle for the majority of these claims and lawsuits. Approximately 40 lawsuits are pending claiming property and related damage. This represents a decrease of about 85 from the number of lawsuits pending at December 31, 2013.
	The company has established review processes to verify and evaluate damage claims. There are several variables that impact the evaluation process including the number of trees on a property, the species of tree with reported damage, the height of the tree, the extent of damage and the possibility for trees to naturally recover over time. Upon receiving claims, DuPont verifies their accuracy and validity which often requires physical review of the property.
	As of December 31, 2013, DuPont had recorded charges of $1,175, within other operating charges, which represents the company's best estimate of the loss associated with resolving these claims. At December 31, 2014, DuPont had accruals of $261 related to these claims and insurance receivables of $35. The company did not take any charges related to this matter in 2014. DuPont recorded income of $210 for insurance recoveries, within other operating charges, for the year ended December 31, 2014. The year ended December 31, 2013 included net charges of $352, consisting of a $425 charge offset by $73 of insurance recoveries. The year ended December 31, 2012 included charges of $575. In January 2015, DuPont reached an agreement to recover an additional $35 from one of its remaining insurance carriers.
	The company has an applicable insurance program with a deductible equal to the first $100 of costs and expenses. Insurance recoveries are recognized when collection of payment is considered probable. The remaining coverage under the insurance program is $300 for costs and expenses in excess of its deductible. DuPont has submitted requests for payment to its insurance carriers for costs associated with this matter. The timing and outcome remain uncertain.
	Litigation
	The company is subject to various legal proceedings arising out of the normal course of its business including product liability, intellectual property, commercial, environmental and antitrust lawsuits. It is not possible to predict the outcome of these various proceedings. Except as otherwise noted, management does not anticipate their resolution will have a materially adverse effect on the company's consolidated financial position or liquidity.  However, the ultimate liabilities could be significant to results of operations in the period recognized.
	PFOA
	DuPont used PFOA (collectively, perfluorooctanoic acids and its salts, including the ammonium salt), as a processing aid to manufacture some fluoropolymer resins at various sites around the world including its Washington Works plant in West Virginia. At December 31, 2014, DuPont has accruals of $14 related to the PFOA matters discussed below.
	The accrual includes charges related to DuPont's obligations under agreements with the U.S. Environmental Protection Agency and voluntary commitments to the New Jersey Department of Environmental Protection. These obligations and voluntary commitments include surveying, sampling and testing drinking water in and around certain company sites and offering treatment or an alternative supply of drinking water if tests indicate the presence of PFOA in drinking water at or greater than the national Provisional Health Advisory.
	Drinking Water Actions
	In August 2001, a class action, captioned Leach v DuPont, was filed in West Virginia state court alleging that residents living near the Washington Works facility had suffered, or may suffer, deleterious health effects from exposure to PFOA in drinking water.
	DuPont and attorneys for the class reached a settlement in 2004 that binds about 80,000 residents. In 2005, DuPont paid the plaintiffs’ attorneys’ fees and expenses of $23 and made a payment of $70, which class counsel designated to fund a community health project.  The company funded a series of health studies which were completed in October 2012 by an independent science panel of experts (the C8 Science Panel). The studies were conducted in communities exposed to PFOA to evaluate available scientific evidence on whether any probable link exists, as defined in the settlement agreement, between exposure to PFOA and human disease.
	The C8 Science Panel found probable links, as defined in the settlement agreement, between exposure to PFOA and pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol.
	In May 2013, a panel of three independent medical doctors released its initial recommendations for screening and diagnostic testing of eligible class members. In September 2014, the medical panel recommended follow-up screening and diagnostic testing three years after initial testing, based on individual results. The medical panel has not communicated its anticipated schedule for completion of its protocol. The company is obligated to fund up to $235 for a medical monitoring program for eligible class members and, in addition, administrative costs associated with the program, including class counsel fees. In January 2012, the company put $1 in an escrow account to fund medical monitoring as required by the settlement agreement.  The court appointed Director of Medical Monitoring has established the program to implement the medical panel's recommendations and the registration process, as well as eligibility screening, is ongoing. Diagnostic screening and testing has begun and associated payments to service providers are being disbursed from the escrow account.
	In addition, under the settlement agreement, the company must continue to provide water treatment designed to reduce the level of PFOA in water to six area water districts, including the Little Hocking Water Association (LHWA), and private well users.
	Class members may pursue personal injury claims against DuPont only for those human diseases for which the C8 Science Panel determined a probable link exists. At December 31, 2014, there were approximately 2,900 lawsuits filed in various federal and state courts in Ohio and West Virginia, an increase of about 2,800 over year end 2013. In accordance with a stipulation reached in the third quarter 2014 and other court procedures, these lawsuits have been or will be served and consolidated in multi-district litigation in Ohio federal court (“MDL”). Based on information currently available to the company the majority of the lawsuits allege personal injury claims associated with high cholesterol and thyroid disease from exposure to PFOA in drinking water.  There are 27 lawsuits alleging wrongful death. Based on comments from attorneys for the plaintiffs, DuPont expects additional lawsuits may be filed. In 2014, six plaintiffs from the MDL were selected for the individual trial. The first trial is scheduled to begin in September 2015, and the second in November 2015. DuPont denies the allegations in these lawsuits and is defending itself vigorously.
	Additional Actions
	An Ohio action brought by the LHWA is ongoing. In addition to general claims of PFOA contamination of drinking water, the action claims “imminent and substantial endangerment to health and or the environment” under the Resource Conservation and Recovery Act (RCRA). In the second quarter 2014, DuPont filed a motion for summary judgment which if granted, will be dispositive of this matter. The LHWA has moved for partial summary judgment. DuPont denies these claims and is defending itself vigorously.
	While it is probable that the company will incur costs related to funding the medical monitoring program, such costs cannot be reasonably estimated due to uncertainties surrounding the level of participation by eligible class members and the scope of testing. DuPont believes that it is reasonably possible that it could incur losses related to the other PFOA matters discussed above; however, a range of such losses, if any, cannot be reasonably estimated at this time.
	Environmental
	The company is also subject to contingencies pursuant to environmental laws and regulations that in the future may require the company to take further action to correct the effects on the environment of prior disposal practices or releases of chemical or petroleum substances by the company or other parties. The company accrues for environmental remediation activities consistent with the policy set forth in Note 1. Much of this liability results from the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, often referred to as Superfund), RCRA and similar state and global laws. These laws require the company to undertake certain investigative, remediation and restoration activities at sites where the company conducts or once conducted operations or at sites where company-generated waste was disposed. The accrual also includes estimated costs related to a number of sites identified by the company for which it is probable that environmental remediation will be required, but which are not currently the subject of enforcement activities.
	Remediation activities vary substantially in duration and cost from site to site. These activities, and their associated costs, depend on the mix of unique site characteristics, evolving remediation technologies, diverse regulatory agencies and enforcement policies, as well as the presence or absence of potentially responsible parties. At December 31, 2014, the Consolidated Balance Sheet included a liability of $478, relating to these matters and, in management's opinion, is appropriate based on existing facts and circumstances. The average time frame, over which the accrued or presently unrecognized amounts may be paid, based on past history, is estimated to be 15-20 years. Considerable uncertainty exists with respect to these costs and, under adverse changes in circumstances, the potential liability may range up to $1,100 above the amount accrued as of December 31, 2014.

	Share Repurchase Program
	In January 2014, the company's Board of Directors authorized a $5,000 share buyback plan that replaced the 2011 plan. There is no required completion date for purchases under the 2014 plan. In February and August 2014, the company entered into two separate accelerated share repurchase (ASR) agreements. The February 2014 ASR agreement was completed in the second quarter of 2014, under which the company purchased and retired 15.1 million shares for $1,000. The August 2014 ASR agreement was completed in the fourth quarter of 2014, under which the company purchased and retired 10.4 million shares for $700. In addition to the ASR agreements, for the year ended December 31, 2014, the company repurchased and retired 4.7 million shares in the open market for a total cost of $300.
	In December 2012, the company's Board of Directors authorized a $1,000 share buyback plan. In February 2013, the company entered into an ASR agreement with a financial institution under which the company used $1,000 of the proceeds from the sale of Performance Coatings for the purchase of shares of common stock. The 2012 $1,000 share buyback plan was completed in the second quarter 2013 through the ASR agreement, under which the company purchased and retired 20.4 million shares.
	During 2012, the company purchased and retired 7.8 million shares at a total cost of $400. These purchases completed the 2001 $2,000 share buyback plan and began purchases under a $2,000 share buyback plan authorized by the company's Board of Directors in April 2011. Under the completed 2001 plan, the company purchased a total of 42.0 million shares. Under the 2011 plan, the company purchased 5.5 million shares at a total cost of $284 as of December 31, 2013.
	Common stock held in treasury is recorded at cost. When retired, the excess of the cost of treasury stock over its par value is allocated between reinvested earnings and additional paid-in capital.
	Set forth below is a reconciliation of common stock share activity for the years ended December 31, 2014, 2013 and 2012:
	Shares of common stock	Issued		Held In Treasury

	Balance December 31, 2014	992,020,000		(87,041,000	)
	Noncontrolling Interest
	In May 2012, the company completed the acquisition of the remaining 28 percent interest in the Solae, LLC joint venture from Bunge Limited for $447. As the purchase of the remaining interest did not result in a change of control, the difference between the carrying value of the noncontrolling interest of $378 and the consideration paid, net of taxes of $78, was recorded as a $9 increase to additional paid-in capital.

General Discussion of Pension and Other Postretirement Benefits [Abstract]
Long Term Employee Benefits	LONG-TERM EMPLOYEE BENEFITS
	The company offers various long-term benefits to its employees. Where permitted by applicable law, the company reserves the right to change, modify or discontinue the plans.
	Defined Benefit Pensions
	The company has both funded and unfunded noncontributory defined benefit pension plans covering a majority of the U.S. employees. Most employees hired on or after January 1, 2007 are not eligible to participate in the U.S. defined benefit pension plans. The benefits under these plans are based primarily on years of service and employees' pay near retirement. The company's funding policy is consistent with the funding requirements of federal laws and regulations. Pension coverage for employees of the company's non-U.S. consolidated subsidiaries is provided, to the extent deemed appropriate, through separate plans. Obligations under such plans are funded by depositing funds with trustees, covered by insurance contracts, or remain unfunded.
	Other Long-term Employee Benefits
	The parent company and certain subsidiaries provide medical, dental and life insurance benefits to pensioners and survivors. The associated plans for retiree benefits are unfunded and the cost of the approved claims is paid from company funds. Essentially all of the cost and liabilities for these retiree benefit plans are attributable to the U.S. parent company plans. The non-Medicare eligible retiree medical plan is contributory with pensioners and survivors' contributions adjusted annually to achieve a 50/50 target sharing of cost increases between the company and pensioners and survivors. In addition, limits are applied to the company's portion of the retiree medical cost coverage. For Medicare eligible pensioners and survivors, the company provides a company-funded Health Reimbursement Arrangement (HRA). Beginning January 1, 2015, eligible employees who retire on and after that date will receive the same life insurance benefit payment, regardless of age.The majority of U.S. employees hired on or after January 1, 2007 are not eligible to participate in the post retirement medical, dental and life insurance plans.
	The company also provides disability benefits to employees. Employee disability benefit plans are insured in many countries. However, primarily in the U.S., such plans are generally self-insured. Obligations and expenses for self-insured plans are reflected in the figures below.
	Summarized information on the company's pension and other long-term employee benefit plans is as follows:

Rate of compensation increase	4.22	%	4.14	%	4.18	%	—	%	4.4	%	4.4	%
For determining U.S. pension plans' net periodic benefit costs, the discount rate, expected return on plan assets and the rate of compensation increase were 4.90 percent, 8.75 percent and 4.50 percent for 2014.
For determining U.S. pension plans' net periodic benefit costs, the discount rate, expected return on plan assets and the rate of compensation increase were 4.10 percent, 8.75 percent and 4.40 percent for 2013.
In connection with the planned sale of the Performance Coatings business (See Note 2), the company updated the discount rate and expected return on plan assets for the U.S. pension plans during 2012. For determining the U.S. pension plans' net periodic benefit costs, the weighted discount rate, weighted expected return on plan assets and the rate of compensation increase were 4.38 percent, 8.96 percent and 4.40 percent for 2012. With the continuing challenges in the global economy, the company lowered its long-term expected return on plan assets during 2012.
In the U.S., the discount rate is developed by matching the expected cash flow of the benefit plans to a yield curve constructed from a portfolio of high quality fixed-income instruments provided by the plan's actuary as of the measurement date. For non-U.S. benefit plans, the company utilizes prevailing long-term high quality corporate bond indices to determine the discount rate applicable to each country at the measurement date.
The long-term rate of return on assets in the U.S. was selected from within the reasonable range of rates determined by historical real returns (net of inflation) for the asset classes covered by the investment policy, expected performance, and projections of inflation over the long-term period during which benefits are payable to plan participants. Consistent with prior years, the long-term rate of return on plan assets in the U.S. reflects the asset allocation of the plan and the effect of the company's active management of the plans' assets. For non-U.S. plans, assumptions reflect economic assumptions applicable to each country.
In October 2014, the Society of Actuaries released final reports of new mortality tables and a mortality improvement scale for measurement of retirement program obligations in the U.S. The company has adopted these tables in measuring the 2014 long-term employee benefits.

Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	5	%	5	%

Assumed health care cost trend rates have a modest effect on the amount reported for the health care plan. A one-percentage point change in assumed health care cost trend rates would have the following effects:

Plan Assets
All pension plan assets in the U.S. are invested through a single master trust fund. The strategic asset allocation for this trust fund is approved by management. The general principles guiding U.S. pension asset investment policies are those embodied in the Employee Retirement Income Security Act of 1974 (ERISA). These principles include discharging the company's investment responsibilities for the exclusive benefit of plan participants and in accordance with the "prudent expert" standard and other ERISA rules and regulations. The company establishes strategic asset allocation percentage targets and appropriate benchmarks for significant asset classes with the aim of achieving a prudent balance between return and risk. Strategic asset allocations in other countries are selected in accordance with the laws and practices of those countries. Where appropriate, asset liability studies are utilized in this process. U.S. plan assets and a portion of non-U.S. plan assets are managed by investment professionals employed by the company. The remaining assets are managed by professional investment firms unrelated to the company. The company's pension investment professionals have discretion to manage the assets within established asset allocation ranges approved by management of the company. Additionally, pension trust funds are permitted to enter into certain contractual arrangements generally described as "derivatives". Derivatives are primarily used to reduce specific market risks, hedge currency and adjust portfolio duration and asset allocation in a cost-effective manner.
The weighted-average target allocation for plan assets of the company's U.S. and non-U.S. pension plans is summarized as follows:
Target allocation for plan assets at December 31,	2014		2013
U.S. equity securities	28	%	27	%
Non-U.S. equity securities	21		21
Fixed income securities	32		33
Hedge funds	2		2
Private market securities	9		10
Real estate	5		7
Cash and cash equivalents	3		—
Total	100	%	100	%
Global equity securities include varying market capitalization levels. U.S. equity investments are primarily large-cap companies. Global fixed income investments include corporate-issued, government-issued and asset-backed securities. Corporate debt investments include a range of credit risk and industry diversification. U.S. fixed income investments are weighted heavier than non-U.S fixed income securities. Other investments include cash and cash equivalents, hedge funds, real estate and private market securities such as interests in private equity and venture capital partnerships.
Fair value calculations may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.
The tables below presents the fair values of the company's pension assets by level within the fair value hierarchy, as described in Note 1, as of December 31, 2014 and 2013, respectively.

The company made a contribution of $500 to its principal U.S. pension plan in 2012. No contributions to its principal U.S. pension plan were made in 2013 or 2014. In 2015, contributions to the principal U.S. pension plan are expected to be less than $50. The company contributed $190, $121 and $233 to its pension plans other than the principal U.S. pension plan, its remaining plans with no plan assets and its other long-term employee benefit plans, respectively, in 2014. The company contributed $197, $116 and $207 to its pension plans other than the principal U.S. pension plan, its remaining plans with no plan assets and its other long-term employee benefit plans, respectively, in 2013. In 2015, the company expects to contribute about the same as 2014 to its pension plans other than the principal U.S. pension plan, its remaining plans with no plan assets and its other long-term employee benefit plans.

Defined Contribution Plan
The company sponsors several defined contribution plans, which cover substantially all U.S. employees. The most significant is the U.S. Retirement Savings Plan (the Plan). This Plan includes a non-leveraged Employee Stock Ownership Plan (ESOP). Employees are not required to participate in the ESOP and those who do are free to diversify out of the ESOP. The purpose of the Plan is to provide retirement savings benefits for employees and to provide employees an opportunity to become stockholders of the company. The Plan is a tax qualified contributory profit sharing plan, with cash or deferred arrangement and any eligible employee of the company may participate. Currently, the company contributes 100 percent of the first 6 percent of the employee's contribution election and also contributes 3 percent of each eligible employee's eligible compensation regardless of the employee's contribution.
The company's contributions to the Plan were $262, $208 and $212 for the years ended December 31, 2014, 2013 and 2012, respectively. The company's matching contributions vest immediately upon contribution. The 3 percent nonmatching company contribution vests for employees with at least three years of service. In addition, the company made contributions to other defined contribution plans of $66, $105 and $124 for the years ended December 31, 2014, 2013 and 2012, respectively. Included in the company's contributions are amounts related to discontinued operations of $0, $2 and $30 for the years ended December 31, 2014, 2013 and 2012, respectively. The company expects to contribute about $340 to its defined contribution plans in 2015.

Compensation Plans [Abstract]
Compensation Plans	COMPENSATION PLANS
	The total stock-based compensation cost included in the Consolidated Income Statements was $151, $129 and $105 for 2014, 2013 and 2012, respectively. The income tax benefits related to stock-based compensation arrangements were $50, $43 and $35 for 2014, 2013 and 2012, respectively.
	In April 2011, the shareholders approved amendments to the DuPont Equity and Incentive Plan (EIP). The EIP provides for equity-based and cash incentive awards to certain employees, directors, and consultants. Under the amended EIP, the maximum number of shares reserved for the grant or settlement of awards is 110 million shares, provided that each share in excess of 30 million that is issued with respect to any award that is not an option or stock appreciation right will be counted against the 110 million share limit as four and one-half shares. At December 31, 2014, approximately 45 million shares were authorized for future grants under the company's EIP. The company satisfies stock option exercises and vesting of time-vested restricted stock units (RSUs) and performance-based restricted stock units (PSUs) with newly issued shares of DuPont common stock.
	The company's Compensation Committee determines the long-term incentive mix, including stock options, RSUs and PSUs and may authorize new grants annually.
	Stock Options
	The exercise price of shares subject to option is equal to the market price of the company's stock on the date of grant. Options granted prior to 2004 expire 10 years from date of grant; options granted between 2004 and 2008 serially vested over a three-year period and carry a six-year option term. Stock option awards granted between 2009 and 2014 expire seven years after the grant date. The plan allows retirement eligible employees to retain any granted awards upon retirement provided the employee has rendered at least six months of service following grant date.
	For purposes of determining the fair value of stock options awards, the company uses the Black-Scholes option pricing model and the assumptions set forth in the table below. The weighted-average grant-date fair value of options granted in 2014, 2013 and 2012 was $13.68, $10.40 and $11.81, respectively.
		2014		2013		2012
	Dividend yield	2.9	%	3.6	%	3.2	%
	Volatility	31.33	%	34.86	%	34.87	%
	Risk-free interest rate	1.7	%	1	%	0.9	%
	Expected life (years)	5.3		5.3		5.3
	The company determines the dividend yield by dividing the current annual dividend on the company's stock by the option exercise price. A historical daily measurement of volatility is determined based on the expected life of the option granted. The risk-free interest rate is determined by reference to the yield on an outstanding U.S. Treasury note with a term equal to the expected life of the option granted. Expected life is determined by reference to the company's historical experience.
	Stock option awards as of December 31, 2014, and changes during the year then ended were as follows:
		Number of		Weighted			Weighted	Aggregate
		Shares		Average			Average	Intrinsic
		(in thousands)		Exercise Price			Remaining	Value
				(per share)			Contractual	(in thousands)
							Term (years)
	Outstanding, December 31, 2013	21,571		$	41.58
	Granted	4,592		$	61.91
	Exercised	(7,035	)	$	36.26
	Forfeited	(168	)	$	55.55
	Cancelled	(65	)	$	49.47
	Outstanding, December 31, 2014	18,895		$	48.34		4.23	$	484,341
	Exercisable, December 31, 2014	9,251		$	41.46		2.96	$	300,498
	The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between the company's closing stock price on the last trading day of 2014 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options at year end. The amount changes based on the fair market value of the company's stock. Total intrinsic value of options exercised for 2014, 2013 and 2012 were $219, $230 and $147, respectively. In 2014, the company realized a tax benefit of $72 from options exercised.
	As of December 31, 2014, $34 of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 1.72 years.
	RSUs and PSUs
	The company issues RSUs that serially vest over a three-year period and, upon vesting, convert one-for-one to DuPont common stock. A retirement eligible employee retains any granted awards upon retirement provided the employee has rendered at least six months of service following the grant date. Additional RSUs are also granted periodically to key senior management employees. These RSUs generally vest over periods ranging from two to five years. The fair value of all stock-settled RSUs is based upon the market price of the underlying common stock as of the grant date.
	The company also grants PSUs to senior leadership. In 2014, there were 348,516 PSUs granted. Vesting for PSUs granted in 2014, 2013 and 2012 is equally based upon corporate revenue growth relative to peer companies and total shareholder return (TSR) relative to peer companies. Performance and payouts are determined independently for each metric. The actual award, delivered as DuPont common stock, can range from zero percent to 200 percent of the original grant. The weighted-average grant-date fair value of the PSUs granted in 2014, subject to the TSR metric, was $80.01, estimated using a Monte Carlo simulation. The weighted-average grant-date fair value of the PSUs, subject to the revenue metric, was based upon the market price of the underlying common stock as of the grant date.
	Non-vested awards of RSUs and PSUs as of December 31, 2014 and 2013 are shown below. The weighted-average grant-date fair value of RSUs and PSUs granted during 2014, 2013 and 2012 was $64.64, $48.06 and $47.17, respectively.
		Number of		Weighted
		Shares		Average
		(in thousands)		Grant Date
				Fair Value
				(per share)
	Nonvested, December 31, 2013	3,765		$	52.41
	Granted	1,623		$	64.64
	Vested	(1,475	)	$	50.68
	Forfeited	(156	)	$	59.73
	Nonvested, December 31, 2014	3,757		$	57.6
	As of December 31, 2014, there was $76 of unrecognized stock-based compensation expense related to nonvested awards. That cost is expected to be recognized over a weighted-average period of 1.88 years. The total fair value of stock units vested during 2014, 2013 and 2012 was $75, $75 and $68, respectively.
	Other Cash-based Awards
	Cash awards under the EIP plan may be granted to employees who have contributed most to the company's success, with consideration being given to the ability to succeed to more important managerial responsibility. Such awards were $38, $60 and $60 for 2014, 2013 and 2012, respectively. The amounts of the awards are dependent on company earnings and are subject to maximum limits as defined under the governing plans.
	In addition, the company has other variable compensation plans under which cash awards may be granted. These plans include the company's regional and local variable compensation plans and Pioneer's Annual Reward Program. Such awards were $151, $317 and $379 for 2014, 2013 and 2012, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Other Hedging Instruments	DERIVATIVES AND OTHER HEDGING INSTRUMENTS
	Objectives and Strategies for Holding Derivative Instruments
	In the ordinary course of business, the company enters into contractual arrangements (derivatives) to reduce its exposure to foreign currency, interest rate and commodity price risks. The company has established a variety of derivative programs to be utilized for financial risk management. These programs reflect varying levels of exposure coverage and time horizons based on an assessment of risk.
	Derivative programs have procedures and controls and are approved by the Corporate Financial Risk Management Committee, consistent with the company's financial risk management policies and guidelines. Derivative instruments used are forwards, options, futures and swaps. The company has not designated any nonderivatives as hedging instruments.
	The company's financial risk management procedures also address counterparty credit approval, limits and routine exposure monitoring and reporting. The counterparties to these contractual arrangements are major financial institutions and major commodity exchanges. The company is exposed to credit loss in the event of nonperformance by these counterparties. The company utilizes collateral support annex agreements with certain counterparties to limit its exposure to credit losses. The company's derivative assets and liabilities are reported on a gross basis in the Consolidated Balance Sheets. The company anticipates performance by counterparties to these contracts and therefore no material loss is expected. Market and counterparty credit risks associated with these instruments are regularly reported to management.
	The notional amounts of the company's derivative instruments were as follows:
	December 31,	2014			2013
	Derivatives designated as hedging instruments:
	Interest rate swaps	$	1,000		$	1,000
	Foreign currency contracts	434			1,107
	Commodity contracts	388			606
	Derivatives not designated as hedging instruments:
	Foreign currency contracts	10,586			9,553
	Commodity contracts	166			281
	Foreign Currency Risk
	The company's objective in managing exposure to foreign currency fluctuations is to reduce earnings and cash flow volatility associated with foreign currency rate changes. Accordingly, the company enters into various contracts that change in value as foreign exchange rates change to protect the value of its existing foreign currency-denominated assets, liabilities, commitments and cash flows.
	The company routinely uses forward exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities of its operations. The primary business objective of this hedging program is to maintain an approximately balanced position in foreign currencies so that exchange gains and losses resulting from exchange rate changes, net of related tax effects, are minimized. The company also uses foreign currency exchange contracts to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues. The objective of the hedge program is to reduce earnings and cash flow volatility related to changes in foreign currency exchange rates.
	Interest Rate Risk
	The company uses interest rate swaps to manage the interest rate mix of the total debt portfolio and related overall cost of borrowing.
	Interest rate swaps involve the exchange of fixed for floating rate interest payments to effectively convert fixed rate debt into floating rate debt based on USD LIBOR. Interest rate swaps allow the company to achieve a target range of floating rate debt.
	Commodity Price Risk
	Commodity price risk management programs serve to reduce exposure to price fluctuations on purchases of inventory such as copper, corn, soybeans and soybean meal. The company enters into over-the-counter and exchange-traded derivative commodity instruments to hedge the commodity price risk associated with agricultural commodity exposures.
	Fair Value Hedges
	Interest Rate Swaps
	At December 31, 2014, the company maintained a number of interest rate swaps, which were implemented at the time debt instruments were issued. All interest rate swaps qualify for the shortcut method of hedge accounting, thus there is no ineffectiveness related to these hedges.
	Cash Flow Hedges
	Foreign Currency Contracts
	The company uses foreign currency exchange instruments such as forwards and options to offset a portion of the company's exposure to certain foreign currency-denominated revenues so that gains and losses on these contracts offset changes in the USD value of the related foreign currency-denominated revenues. In addition, the company occasionally uses forward exchange contracts to offset a portion of the company’s exposure to certain foreign currency-denominated transactions such as capital expenditures.
	Commodity Contracts
	The company enters into over-the-counter and exchange-traded derivative commodity instruments, including options, futures and swaps, to hedge the commodity price risk associated with agriculture commodity exposures.
	While each risk management program has a different time maturity period, most programs currently do not extend beyond the next two-year period. Cash flow hedge results are reclassified into earnings during the same period in which the related exposure impacts earnings. Reclassifications are made sooner if it appears that a forecasted transaction will not materialize. The following table summarizes the after-tax effect of cash flow hedges on accumulated other comprehensive income (loss) for the years ended December 31, 2014 and 2013:
	December 31,	2014			2013
	Beginning balance	$	(48	)	$	3
	Additions and revaluations of derivatives designated as cash flow hedges	33			(36		)
	Clearance of hedge results to earnings	9			(15		)
	Ending balance	$	(6	)	$	(48	)
	At December 31, 2014, an after-tax net loss of $6 is expected to be reclassified from accumulated other comprehensive income (loss) into earnings over the next twelve months.
	Derivatives not Designated in Hedging Relationships
	Foreign Currency Contracts
	The company routinely uses forward exchange contracts to reduce its net exposure, by currency, related to foreign currency-denominated monetary assets and liabilities of its operations so that exchange gains and losses resulting from exchange rate changes are minimized. The netting of such exposures precludes the use of hedge accounting; however, the required revaluation of the forward contracts and the associated foreign currency-denominated monetary assets and liabilities intends to achieve a minimal earnings impact, after taxes. Additionally, the company utilized cross-currency swaps to hedge foreign currency fluctuations on long-term intercompany loans. These swaps matured during 2013.
	Commodity Contracts
	The company utilizes options, futures and swaps that are not designated as hedging instruments to reduce exposure to commodity price fluctuations on purchases of inventory such as corn, soybeans and soybean meal.
	Fair Values of Derivative Instruments
	The table below presents the fair values of the company's derivative assets and liabilities within the fair value hierarchy, as described in Note 1, as of December 31, 2014 and 2013.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION
	The company consists of 12 businesses which are aggregated into 7 reportable segments based on similar economic characteristics, the nature of the products and production processes, end-use markets, channels of distribution and regulatory environment. The company's reportable segments are Agriculture, Electronics & Communications, Industrial Biosciences, Nutrition & Health, Performance Chemicals, Performance Materials and Safety & Protection. The company includes certain embryonic businesses not included in the reportable segments, such as pre-commercial programs, and nonaligned businesses in Other.
	Major products by segment include: Agriculture (corn hybrids and soybean varieties, herbicides, fungicides and insecticides); Electronics & Communications (photopolymers and electronic materials); Industrial Biosciences (enzymes and bio-based materials); Nutrition & Health (cultures, emulsifiers, texturants, natural sweeteners and soy-based food ingredients); Performance Chemicals (fluorochemicals, fluoropolymers, specialty and industrial chemicals, and white pigments); Performance Materials (engineering polymers, packaging and industrial polymers, films and elastomers); and Safety & Protection (nonwovens, aramids and solid surfaces). The company operates globally in substantially all of its product lines.
	In general, the accounting policies of the segments are the same as those described in Note 1. Exceptions are noted as follows and are shown in the reconciliations below. Segment sales include transfers to another business segment. Products are transferred between segments on a basis intended to reflect, as nearly as practicable, the market value of the products. Segment net assets includes net working capital, net property, plant and equipment, and other noncurrent operating assets and liabilities of the segment. Affiliate net assets (pro rata share) excludes borrowing and other long-term liabilities. Depreciation and amortization includes depreciation on research and development facilities and amortization of other intangible assets, excluding write-down of assets. Prior years' data have been reclassified to reflect the current organizational structure.
	The earnings from the previous Pharmaceuticals segment are insignificant in 2014 and therefore the results are reported within Other. Viton® fluoroelastomer products (Viton®) will be included in the Performance Chemicals separation and therefore the results are reported within Performance Chemicals. Viton® was previously reported within Performance Materials. Reclassifications of prior year data have been made to conform to current year classifications.
	Segment pre-tax operating income (loss) (PTOI) is defined as income (loss) from continuing operations before income taxes excluding non-operating pension and other postretirement employee benefit costs, exchange gains (losses), corporate expenses and interest.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Preparation of Financial Statements	Preparation of Financial Statements
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Basis of Consolidation	Basis of Consolidation
	The Consolidated Financial Statements include the accounts of the company, subsidiaries in which a controlling interest is maintained and variable interest entities (VIEs) for which DuPont is the primary beneficiary. For those consolidated subsidiaries in which the company's ownership is less than 100 percent, the outside stockholders' interests are shown as noncontrolling interests. Investments in affiliates over which the company has significant influence but not a controlling interest are carried on the equity method. At December 31, 2014, the assets, liabilities and operations of VIEs for which DuPont is the primary beneficiary were not material to the Consolidated Financial Statements of the company.
	The company is also involved with certain joint ventures accounted for under the equity method of accounting that are VIEs. The company is not the primary beneficiary, as the nature of the company's involvement with the VIEs does not provide it the power to direct the VIEs significant activities. Future events may require these VIEs to be consolidated if the company becomes the primary beneficiary. At December 31, 2014, the maximum exposure to loss related to the unconsolidated VIEs is not considered material to the Consolidated Financial Statements of the company.
Basis of Presentation	Basis of Presentation
	Certain reclassifications of prior year's data have been made to conform to current year's presentation.
	The company’s cost structure has been impacted by the global, multi-year initiative to redesign its global organization and operating model to improve productivity and agility across all businesses and functions. Effective December 31, 2014, in order to better align to the transforming company’s organization and resulting cost structure, certain costs were reclassified from other operating charges to selling, general and administrative expenses. Prior year data has been reclassified to conform to current year presentation.
	In November 2013, DuPont entered into a definitive agreement to sell Glass Laminating Solutions/Vinyls (GLS/Vinyls), a part of the Performance Materials segment. The assets related to GLS/Vinyls at December 31, 2013 are presented as held for sale in the Consolidated Balance Sheet. In June 2014, the company sold GLS/Vinyls to Kuraray Co. Ltd. The sale of GLS/Vinyls does not meet the criteria for discontinued operations and as such, earnings are included in the company’s income from continuing operations.
	In February 2013, the company sold its Performance Coatings business (which represented a reportable segment). In accordance with GAAP, the results of Performance Coatings are presented as discontinued operations and, as such, have been excluded from continuing operations and segment results for all periods presented. The sum of the individual earnings per share amounts from continuing and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to Performance Coatings have not been segregated and are included in the Consolidated Statements of Cash Flows and Comprehensive Income, respectively, for all periods presented. Amounts related to Performance Coatings are consistently included in or excluded from the Notes to the Consolidated Financial Statements based on the financial statement line item and period of each disclosure.
	See Note 2 to the Consolidated Financial Statements for further information relating to the above matters.
Revenue Recognition	Revenue Recognition
	The company recognizes revenue when the earnings process is complete. The company's revenues are from the sale of a wide range of products to a diversified base of customers around the world. Revenue for product sales is recognized upon delivery, when title and risk of loss have been transferred, collectability is reasonably assured and pricing is fixed or determinable. A majority of product sales are sold FOB (free on board) shipping point or, with respect to non United States of America (U.S.) customers, an equivalent basis. Accruals are made for sales returns and other allowances based on the company's experience. The company accounts for cash sales incentives as a reduction in sales and noncash sales incentives as a charge to cost of goods sold or selling expense, depending on the nature of the incentive. Amounts billed to customers for shipping and handling fees are included in net sales and costs incurred by the company for the delivery of goods are classified as cost of goods sold in the Consolidated Income Statements. Taxes on revenue-producing transactions are excluded from net sales.
	The company periodically enters into prepayment contracts with customers in the Agriculture segment and receives advance payments for product to be delivered in future periods. These advance payments are recorded as deferred revenue (classified as other accrued liabilities) or debt, depending on the nature of the program. Revenue associated with advance payments is recognized as shipments are made and title, ownership and risk of loss pass to the customer.
	Licensing and royalty income is recognized in accordance with agreed upon terms, when performance obligations are satisfied, the amount is fixed or determinable and collectability is reasonably assured
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash equivalents represent investments with maturities of three months or less from time of purchase. They are carried at cost plus accrued interest. The estimated fair value of the company's cash equivalents, which approximates carrying value as of December 31, 2014 and 2013, was determined using level 1 and level 2 inputs within the fair value hierarchy, as described below. Level 1 measurements were based on observed net asset values and level 2 measurements were based on current interest rates for similar investments with comparable credit risk and time to maturity. The company held $1,436 and $5,116 of money market funds (level 1 measurements) as of December 31, 2014 and 2013, respectively.  The company held $3,293 and $2,256 of other cash equivalents (level 2 measurements) as of December 31, 2014 and 2013, respectively.
Marketable Securities	Marketable Securities
	Marketable securities represent investments in fixed and floating rate financial instruments with maturities greater than three months and up to twelve months at time of purchase. They are classified as held-to-maturity and recorded at amortized cost. The carrying value approximates fair value due to the short-term nature of the investments.
Fair Value Measurements	Fair Value Measurements
	Under the accounting for fair value measurements and disclosures, a fair value hierarchy was established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). A financial instrument's level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
	The company uses the following valuation techniques to measure fair value for its assets and liabilities:
	Level 1	–	Quoted market prices in active markets for identical assets or liabilities;
	Level 2	–	Significant other observable inputs (e.g. quoted prices for similar items in active markets, quoted prices for identical or similar items in markets that are not active, inputs other than quoted prices that are observable such as interest rate and yield curves, and market-corroborated inputs);
	Level 3	–	Unobservable inputs for the asset or liability, which are valued based on management's estimates of assumptions that market participants would use in pricing the asset or liability.
Inventories	Inventories
	The company's inventories are valued at the lower of cost or market. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead. Stores and supplies are valued at cost or market, whichever is lower; cost is generally determined by the average cost method.
	As of December 31, 2014 and 2013 approximately 50 percent, 25 percent and 25 percent of the company’s inventories were accounted for under the first-in first out (FIFO), last-in first out (LIFO) and average cost methods, respectively. Inventories accounted for under the FIFO method are primarily comprised of products with shorter shelf lives such as seeds, certain food-ingredients and enzymes.
Property, Plant and Equipment	Property, Plant and Equipment
	Property, plant and equipment is carried at cost and is depreciated using the straight-line method. Property, plant and equipment placed in service prior to 1995 is depreciated under the sum-of-the-years' digits method or other substantially similar methods. Substantially all equipment and buildings are depreciated over useful lives ranging from 15 to 25 years. Capitalizable costs associated with computer software for internal use are amortized on a straight-line basis over 5 to 7 years. When assets are surrendered, retired, sold or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the accounts and included in determining gain or loss on such disposals.
	Maintenance and repairs are charged to operations; replacements and improvements are capitalized.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets
	Goodwill represents the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. The company's fair value methodology is based on prices of similar assets or other valuation methodologies including discounted cash flow techniques. During the third quarter 2014, the company changed its annual impairment testing from September 30th to July 1st. The company believes this timing is preferable as it better aligns the goodwill impairment test with its strategic business planning cycle. This change did not result in the delay, acceleration or avoidance of an impairment charge. The change was applied prospectively, as retrospective application would have been impractical because the company is unable to objectively select assumptions that would have been used in previous periods without the benefit of hindsight. The company completed its annual impairment testing in the third quarter of 2014 and determined that no adjustments to the carrying value of goodwill or indefinite lived intangible assets were necessary.
	Definite-lived intangible assets, such as purchased and licensed technology, patents and customer lists are amortized over their estimated useful lives, generally for periods ranging from 1 to 20 years or amortized based on units of production. The company continually evaluates the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they are removed from the Consolidated Balance Sheets.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets
	The company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from the assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. The company's fair value methodology is an estimate of fair market value which is made based on prices of similar assets or other valuation methodologies including present value techniques. Long-lived assets to be disposed of other than by sale are classified as held for use until their disposal. Long-lived assets to be disposed of by sale are classified as held for sale and are reported at the lower of carrying amount or fair market value less cost to sell. Depreciation is discontinued for long-lived assets classified as held for sale.
Research and Development	Research and Development
	Research and development costs are expensed as incurred. Research and development expenses include costs (primarily consisting of employee costs, materials, contract services, research agreements, and other external spend) relating to the discovery and development of new products, enhancement of existing products and regulatory approval of new and existing products.
Environmental	Environmental
	Accruals for environmental matters are recorded in operating expenses when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Accrued liabilities do not include claims against third parties and are not discounted.
	Costs related to environmental remediation and restoration are charged to expense. Other environmental costs are also charged to expense unless they increase the value of the property or reduce or prevent contamination from future operations, in which case, they are capitalized.
Asset Retirement Obligations	Asset Retirement Obligations
	The company records asset retirement obligations at fair value at the time the liability is incurred. Accretion expense is recognized as an operating expense using the credit-adjusted risk-free interest rate in effect when the liability was recognized. The associated asset retirement obligations are capitalized as part of the carrying amount of the long-lived asset and depreciated over the estimated remaining useful life of the asset, generally for periods ranging from 1 to 25 years.
Litigation	Litigation
	The company accrues for liabilities related to litigation matters when the information available indicates that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs such as outside counsel fees and expenses are charged to expense in the period incurred.
Insurance/Self-Insurance	Insurance/Self-Insurance
	The company self-insures certain risks where permitted by law or regulation, including workers' compensation, vehicle liability and employee related benefits. Liabilities associated with these risks are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions. For other risks, the company uses a combination of insurance and self-insurance, reflecting comprehensive reviews of relevant risks. A receivable for an insurance recovery is generally recognized when the loss has occurred and collection is considered probable.
Income Taxes	Income Taxes
	The provision for income taxes is 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 basis 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 invested. Investment tax credits or grants are accounted for in the period earned (the flow-through method). Interest accrued related to unrecognized tax benefits is included in miscellaneous income and expenses, net, within other income, net. Income tax related penalties are included in the provision for income taxes.
Foreign Currency Translation	Foreign Currency Translation
	The company's worldwide operations utilize the U.S. dollar (USD) or local currency as the functional currency, where applicable. The company identifies its separate and distinct foreign entities and groups the foreign entities into two categories: 1) extension of the parent (USD functional currency) and 2) self-contained (local functional currency). If a foreign entity does not align with either category, factors are evaluated and a judgment is made to determine the functional currency.
	For foreign entities where the USD is the functional currency, all foreign currency asset and liability amounts are remeasured into USD at end-of-period exchange rates, except for inventories, prepaid expenses, property, plant and equipment, goodwill and other intangible assets, which are remeasured at historical rates. Foreign currency income and expenses are remeasured at average exchange rates in effect during the year, except for expenses related to balance sheet amounts remeasured at historical exchange rates. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in income in the period in which they occur.
	For foreign entities where the local currency is the functional currency, assets and liabilities denominated in local currencies are translated into USD at end-of-period exchange rates and the resultant translation adjustments are reported, net of their related tax effects, as a component of accumulated other comprehensive income (loss) in equity. Assets and liabilities denominated in other than the local currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are included in income in the period in which they occur. Income and expenses are translated into USD at average exchange rates in effect during the period.
	The company changes the functional currency of its separate and distinct foreign entities only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed. As a result of the separation of its Performance Chemicals segment, coupled with the company’s redesign initiative, the functional currency at certain of the company’s foreign entities is being re-evaluated and, in some cases, will result in a change in the foreign entities’ functional currency during 2015. This re-evaluation will not impact the company's results of operations.
	Venezuelan Foreign Currency
	Venezuela is considered a highly inflationary economy under GAAP and the USD is the functional currency for the company's subsidiaries in Venezuela. During the first quarter 2014, the Venezuelan government enacted certain changes to the country’s foreign exchange systems including the expansion of the use of the Complementary System of Foreign Currency Acquirement (SICAD 1) auction rate and introduction of the SICAD 2 auction process. The official exchange rate continues to be set through the National Center for Foreign Commerce (CENCOEX, previously CADIVI) at 6.3 Bolivar Fuertes (BsF) to USD. Based on its evaluation of the restrictions and limitations affecting the availability of specific exchange rate mechanisms, management has concluded that the SICAD 2 auction process would be the most likely mechanism available. As a result, effective June 30, 2014, the company changed from the official exchange rate to the SICAD 2 exchange rate of 49.98, to remeasure its BsF denominated net monetary assets which resulted in a pre-tax charge of $58. The charge is recorded within other income, net in the company's Consolidated Income Statements for the year ended December 31, 2014. The company expects it will continue to use the SICAD 2 exchange rate to remeasure its Venezuelan BsF denominated revenues, expenses and net monetary assets unless facts and circumstances change.
Hedging and Trading Activities	Hedging and Trading Activities
	Derivative instruments are reported in the Consolidated Balance Sheets at their fair values. For derivative instruments designated as fair value hedges, changes in the fair values of the derivative instruments will generally be offset in the income statement by changes in the fair value of the hedged items. For derivative instruments designated as cash flow hedges, the effective portion of any hedge is reported in accumulated other comprehensive income (loss) until it is cleared to earnings during the same period in which the hedged item affects earnings. The ineffective portion of all hedges is recognized in current period earnings. Changes in the fair values of derivative instruments that are not designated as hedges are recorded in current period earnings.
	In the event that a derivative designated as a hedge of a firm commitment or an anticipated transaction is terminated prior to the maturation of the hedged transaction, gains or losses realized at termination are deferred and included in the measurement of the hedged transaction. If a hedged transaction matures, or is sold, extinguished, or terminated prior to the maturity of a derivative designated as a hedge of such transaction, gains or losses associated with the derivative through the date the transaction matured are included in the measurement of the hedged transaction and the derivative is reclassified as for trading purposes. Derivatives designated as a hedge of an anticipated transaction are reclassified as for trading purposes if the anticipated transaction is no longer probable.
	Cash flows from derivative instruments accounted for as either fair value hedges or cash flow hedges are reported in the same category as the cash flows from the items being hedged. Cash flows from all other derivative instruments are generally reported as investing activities in the Consolidated Statements of Cash Flows. See Note 19 for additional discussion regarding the company's objectives and strategies for derivative instruments.
Segment Reporting Policy	In general, the accounting policies of the segments are the same as those described in Note 1. Exceptions are noted as follows and are shown in the reconciliations below. Segment sales include transfers to another business segment. Products are transferred between segments on a basis intended to reflect, as nearly as practicable, the market value of the products. Segment net assets includes net working capital, net property, plant and equipment, and other noncurrent operating assets and liabilities of the segment. Affiliate net assets (pro rata share) excludes borrowing and other long-term liabilities. Depreciation and amortization includes depreciation on research and development facilities and amortization of other intangible assets, excluding write-down of assets. Prior years' data have been reclassified to reflect the current organizational structure.
New Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) and the International Accounting Standards Board (IASB) jointly issued Accounting Standards Update (ASU) No. 2014-9, Revenue from Contracts with Customers (Topic 606), which clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP and International Financial Reporting Standards (IFRS). The core principle of the 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. The ASU is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted under GAAP and retrospective application is permitted, but not required. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations.
	In April 2014, the FASB issued authoritative guidance amending existing requirements for reporting discontinued operations.  Under the new guidance, discontinued operations reporting will be limited to disposal transactions that represent strategic shifts having a major effect on operations and financial results. The amended guidance also enhances disclosures and requires assets and liabilities of a discontinued operation to be classified as such for all periods presented in the financial statements. Public entities will apply the amended guidance prospectively to all disposals occurring within annual periods beginning on or after December 15, 2014 and interim periods within those years. The company will adopt this standard on January 1, 2015. Due to the change in requirements for reporting discontinued operations described above, presentation and disclosures of future disposal transactions after adoption may be different than under current standards.

	1.	The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains (losses) are recorded in other income, net and the related tax impact is recorded in provision for income taxes on continuing operations on the Consolidated Income Statements. Exchange gains (losses) related to earnings of affiliates was $0, $4 and $3 for 2014, 2013 and 2012, respectively. The $135 net exchange gain for the year ended December 31, 2014, includes $(58), $(46) and $(14) exchange losses, associated with the devaluation of the Venezuelan bolivar, Ukrainian hryvnia, and Argentinian peso, respectively. The $(128) net exchange loss for the year ended December 31, 2013, includes a $(33) exchange loss, associated with the devaluation of the Venezuelan bolivar.
