Accounting Policies [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements: Basis of Presentation These interim statements and related management’s discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the related notes and management’s discussion and analysis of results of operations, liquidity and capital resources included in our 2016 Annual Report on Form 10-K (“ 2016 Form 10-K”). These interim statements are unaudited. The year-end balance sheet data included in this Form 10-Q was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America. We have historically operated and continue to operate on a 52/53 week fiscal year ending on the Friday closest to the last day of the quarter. For ease of presentation, September 30 and December 31 are used consistently throughout this Form 10-Q and these interim financial statements and related notes to represent the period-end dates. For the 2017 and 2016 quarters, the actual closing dates were September 29, and September 30, respectively. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. When used herein, the terms “IFF,” the “Company,” “we,” “us” and “our” mean International Flavors & Fragrances Inc. and its consolidated subsidiaries. Reclassifications and Revisions Certain prior year amounts have been reclassified and revised to conform with current year presentation. The Consolidated Statement of Comprehensive Income has been revised to properly reflect Gain on sales of fixed assets within Operating profit for the three and nine months ending September 30, 2016. These amounts were previously included in Other (income) expense, net. In addition, approximately $5.4 million of expense was recorded during the first quarter of 2017 for a tax assessment relating to prior periods. The Consolidated Statement of Cash Flows has been revised to properly reclassify $5.4 million from Net cash used in financing activities to Net cash provided by operating activities for the nine months ended September 30, 2016. These adjustments were not material to the current and previously-issued financial statements. Recent Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued amendments to the Derivatives and Hedging guidance which eliminates the requirement to separately measure and present hedge ineffectiveness and aligns the presentation of hedge gains and losses with the underlying hedge item. This guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The amended presentation and disclosure requirements should be applied prospectively while the amendments to cash flow and net investment hedge relationships should be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In May 2017, the FASB issued amendments to the Compensation - Stock Compensation guidance which clarifies changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect this guidance to have an impact on its Consolidated Financial Statements as it is not the Company's practice to modify the terms or conditions of a share-based payment award after it has been granted. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires employers that present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and postretirement costs in operating expenses. This guidance is effective, and should be applied retrospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The Company expects the impact that this guidance will have on its Consolidated Statement of Comprehensive Income will be an increase in operating expenses of approximately $15 million and $30 million for the fiscal years 2016 and 2017, respectively. There will be no impact to Net income in either period. In January 2017, the FASB issued amendments to the Business Combination guidance which clarifies the definition of a business in order to assist companies when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance will be effective prospectively for annual and interim periods beginning after December 15, 2017. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and on accounting for future acquisitions. In January 2017, the FASB issued an amendment to the Goodwill Impairment guidance which eliminates Step 2 from the goodwill impairment test. This guidance will be effective for fiscal years beginning after December 15, 2019. Early adoption is permitted and the Company has elected to early adopt this guidance and will apply it to its existing annual impairment review policy for fiscal year 2017. The Company does not expect this adoption to have an impact on its consolidated financial statements. In October 2016, the FASB issued authoritative guidance which allows for the immediate recognition of current and deferred income tax impact on intra-entity asset transfers, excluding inventory. This guidance will be effective for fiscal years beginning after December 15, 2017. The Company adopted this guidance in the first quarter of fiscal year 2017 and accordingly, recorded a cumulative-effect adjustment to Retained earnings that reduced Other assets and adjusted Deferred income taxes by a net amount of approximately $33 million . In August 2016, the FASB issued authoritative guidance which requires changes to the classification of certain activities within the statement of cash flows. This guidance will be effective for annual and interim periods beginning after December 15, 2017. Early adoption will be permitted for all entities. The Company does not expect this adoption to have a significant impact on its Consolidated Statement of Cash Flows. In March 2016, the FASB issued authoritative guidance which requires changes to several aspects of the accounting for share-based payment transactions, including the treatment of income tax consequences, classification of awards as either equity or liabilities, and classification of certain items on the statement of cash flows. This guidance was effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The standard requires that employee taxes paid when an employer withholds shares be presented in the Consolidated Statement of Cash Flows as a financing activity instead of an operating activity. The Company adopted this change retrospectively. The adoption resulted in a $11.5 million and $13.3 million reclassification from Net cash provided by operating activities to Net cash provided by financing activities on the Consolidated Statement of Cash Flows as of September 30, 2017 and 2016, respectively. In addition, the standard requires that excess tax benefits presented in the Consolidated Statement of Cash Flows be classified as an operating activity instead of a financing activity. The Company adopted this change retrospectively. The adoption resulted in a $3.2 million and $4.5 million reclassification from Net cash provided by financing activities to Net cash provided by operating activities on the Consolidated Statement of Cash Flows as of September 30, 2017 and 2016, respectively. The standard also requires all excess tax benefits/deficiencies be recognized as income tax expense/benefit in the Consolidated Statement of Comprehensive Income. This guidance has been applied prospectively. This change resulted in a $3.2 million benefit to income tax expense for the period ended September 30, 2017 . The 2016 period included a $1.2 million benefit to equity, which has not been retrospectively adjusted. The full year 2016 benefit to equity was $5.3 million . Additionally, the standard allows the Company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to be forfeited or account for forfeitures as they occur. The Company has elected to continue to account for forfeitures using an estimate of awards expected to be forfeited. In February 2016, the FASB issued authoritative guidance which requires changes to the accounting for leases. The new guidance establishes a new lease accounting model, that requires entities to record assets and liabilities related to leases on the balance sheet for certain types of leases. The guidance will be effective for annual and interim periods beginning after December 15, 2018. Early adoption will be permitted for all entities. The Company expects the adoption of this guidance will result in significant increases to assets and liabilities on its Consolidated Balance Sheet and is still evaluating the impact on its Consolidated Statement of Comprehensive Income. In May 2014, the FASB issued authoritative guidance that provides for a comprehensive model to be used in accounting for revenue arising from contracts with customers. Under this standard, revenue will be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. This guidance is applicable to all entities and is effective for annual and interim periods beginning after December 15, 2017. Companies have the option to apply the new guidance under a retrospective approach to each prior reporting period presented or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Balance Sheet. The Company has determined that it will adopt this guidance using the modified retrospective approach. The Company is evaluating the impact of the new standard, including updates to the standard that were issued by the FASB. In particular, the Company has reviewed the nature of its larger customer relationships and is in the process of reviewing the nature of potential regional variations in all aspects of its customer base regardless of size. Based on the work performed to date, the Company expects to conduct further review and analysis of certain areas that may lead to changes in the manner in which the Company recognizes revenue, including the customized nature of the product, consignment arrangements, rebates, upfront costs, shipping terms and documentation other than formal contracts. As a result, the financial statement impact has not yet been determined. The Company continues to evaluate the potential impact of this standard on its consolidated financial statements and related disclosures. Accounts Receivable The Company sells certain accounts receivable on a non-recourse basis to unrelated financial institutions under “factoring” agreements that are sponsored, solely and individually, by certain customers. The Company accounts for these transactions as sales of receivables, removes the receivables sold from its financial statements, and records cash proceeds when received by the Company. The beneficial impact on cash provided by operations from participating in these programs increased approximately $12.1 million for the nine months ended September 30, 2017 compared to an increase of approximately $25.8 million for the nine months ended September 30, 2016 . The cost of participating in these programs was immaterial to our results in all periods. Currency Translation Adjustment Reclassification During the first quarter of 2017, the Company recorded income of approximately $12.2 million related to a foreign currency exchange gain from the release of a currency translation adjustment upon the liquidation of a foreign entity in 2017. This amount was recorded to Other (income) expense, net.

Earnings Per Share [Abstract]
Net Income Per Share	Net Income Per Share: Net income per share is based on the weighted average number of shares outstanding. A reconciliation of the shares used in the computation of basic and diluted net income per share is as follows: Three Months Ended September 30, Nine Months Ended September 30, (SHARES IN THOUSANDS) 2017 2016 2017 2016 Basic 79,063 79,580 79,072 79,727 Assumed dilution under stock plans 299 355 281 340 Diluted 79,362 79,935 79,353 80,067 There were no stock options or stock-settled appreciation rights (“SSARs”) excluded from the computation of diluted net income per share for the three and nine months ended September 30, 2017 . An immaterial amount of SSARs were excluded from the 2016 period. The Company has issued shares of purchased restricted common stock and purchased restricted common stock units (collectively “PRSUs”) which contain rights to nonforfeitable dividends while these shares are outstanding and thus are considered participating securities. Such securities are required to be included in the computation of basic and diluted earnings per share pursuant to the two-class method. The Company did not present the two-class method since the difference between basic and diluted net income per share for both unrestricted common shareholders and PRSU shareholders was less than $0.01 per share for each period presented, and the number of PRSUs outstanding as of September 30, 2017 and 2016 was immaterial. Net income allocated to such PRSUs was $0.2 million for both the three months ended September 30, 2017 and 2016 and was $0.7 million and $0.8 million for the nine months ended September 30, 2017 and 2016 , respectively.

Business Combinations [Abstract]
Acquisitions	Acquisitions: 2017 Activity PowderPure On April 7, 2017, the Company completed the acquisition of 100% of the outstanding shares of Columbia PhytoTechnology, LLC d/b/a PowderPure ("PowderPure"), a privately-held flavors company with facilities in North America. The acquisition was accounted for under the purchase method. PowderPure was acquired to expand expertise in, and product offerings of, clean label solutions within the Flavors business. The Company paid approximately $55 million including $0.3 million of cash acquired for this acquisition, which was funded from existing resources including use of its revolving credit facility. Additionally, the Company recorded an accrual of approximately $1.4 million representing the current estimate of additional contingent consideration payable to the former owners of PowderPure. (The maximum earnout payable is $10 million upon satisfaction of certain performance metrics). The purchase price exceeded the preliminary fair value of existing net assets by approximately $46.7 million . The excess was allocated principally to identifiable intangible assets including approximately $27.5 million to proprietary technology, approximately $4.5 million to trade name and approximately $0.8 million to customer relationships, and approximately $13.9 million of goodwill (which is deductible for tax purposes). Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents the value the Company expects to achieve from its increased exposure to clean label products within the Company's existing Flavors business. The intangible assets are being amortized over the following estimated useful lives: proprietary technology, 14 years, trade name, 14 years, and customer relationships, 4 years. The purchase price allocation is preliminary pending the finalization of the values of intangible assets, finalization of working capital and the finalization of estimated useful lives. The purchase price allocation is expected to be completed by the fourth quarter of 2017. No pro forma financial information for 2017 and 2016 is presented as the acquisition was not material to the consolidated financial statements. Fragrance Resources On January 17, 2017, the Company completed the acquisition of 100% of the outstanding shares of Fragrance Resources, a privately-held fragrance company with facilities in Germany, North America, France, and China. The acquisition was accounted for under the purchase method. Fragrance Resources was acquired to strengthen the North American and German Fragrances business. The Company paid approximately Euro 142.0 million (approximately $150.5 million ) including approximately Euro 13.7 million (approximately $14.5 million ) of cash acquired for this acquisition, which was funded from existing resources including use of its revolving credit facility. The purchase price exceeded the preliminary fair value of existing net assets by approximately $122.1 million . The excess was allocated principally to identifiable intangible assets including approximately $59.6 million related to customer relationships, approximately $6.1 million related to proprietary technology and trade name, and approximately $79.4 million of goodwill (which is not deductible for tax purposes) and approximately $23.0 million of net deferred tax liability. Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents synergies from the addition of Fragrance Resources to the Company's existing Fragrances business. The intangible assets are being amortized over the following estimated useful lives: trade name, 2 years, proprietary technology, 5 years and customer relationships, 12 - 16 years. The purchase price allocation is preliminary pending the finalization of the values of intangible assets, principally customer relationships, finalization of working capital calculations and the finalization of estimated useful lives. The purchase price allocation is expected to be completed by the fourth quarter of 2017. No pro forma financial information for 2017 and 2016 is presented as the acquisition was not material to the consolidated financial statements. 2016 Activity David Michael On October 7, 2016, the Company completed the acquisition of 100% of the outstanding shares of David Michael & Company, Inc. ("David Michael"). The acquisition was accounted for under the purchase method. David Michael was acquired to strengthen the North American flavors business. The Company paid approximately $242.6 million (including $5.1 million of cash acquired) for this acquisition, which was funded from existing resources. The preliminary purchase price allocation was updated during the first quarter of 2017, resulting in a reduction in allocation of value to customer relationships. The related reduction in amortization expense was not material to the Consolidated Statement of Comprehensive Income. The purchase price allocation was finalized during the second quarter of 2017. Additionally, during the second quarter of 2017, the Company finalized the working capital adjustment and paid an additional $0.6 million . The purchase price exceeded the fair value of existing net assets by approximately $168.7 million . The excess was allocated principally to identifiable intangible assets including approximately $50.0 million related to customer relationships, approximately $8.4 million related to proprietary technology and trade name, and approximately $110.2 million of goodwill (which is deductible for tax purposes). Goodwill is the excess of the purchase price over the fair value of net assets acquired and represents synergies from the addition of David Michael to the Company's existing Flavors business. The intangible assets are being amortized over the following estimated useful lives: trade name, 2 years, proprietary technology, 5 years and customer relationships, 18 - 20 years. No pro forma financial information for 2016 is presented as the impact of the acquisition was immaterial to the Consolidated Statement of Comprehensive Income.

Restructuring and Related Activities [Abstract]
Restructuring and Other Charges, Net	Restructuring and Other Charges, Net: 2017 Productivity Program On February 15, 2017, the Company announced that it was adopting a multi-year productivity program designed to improve overall financial performance, provide flexibility to invest in growth opportunities and drive long-term value creation. In connection with this program, the Company expects to optimize its global footprint and simplify its organizational structures globally. In connection with this initiative, the Company expects to incur cumulative, pre-tax cash charges of between $30 - $35 million , consisting primarily of $21 - $22 million in personnel-related costs and an estimated $9 - $13 million in facility-related costs, such as lease termination, and integration-related costs. In addition, the Company may incur up to $5 million of accelerated depreciation. The Company recorded $16.5 million of charges related to personnel-related costs and lease termination costs through the third quarter of 2017 , of which $3.2 million was recorded during the third quarter of 2017, with the remainder of the personnel-related and other costs expected to be recognized by the end of 2018. The Company made payments of $10.0 million related to severance in 2017 . The overall charges were split approximately evenly between Flavors and Fragrances. This initiative is expected to result in the reduction of approximately 370 members of the Company’s global workforce, including acquired entities, in various parts of the organization. 2015 Severance Charges During 2015, the Company established a series of initiatives intended to streamline its management structure, simplify decision-making and accountability, better leverage and align its capabilities across the organization and improve efficiency of its global manufacturing and operations network. As a result, the Company recorded charges for severance and related costs pertaining to approximately 150 positions that were affected. During 2017 , the Company made payments of $0.2 million related to severance and recorded a credit of $2.3 million related to the reversal of severance accruals that were determined to be no longer required. No further actions are expected in 2017 related to these 2015 initiatives. Changes in employee-related restructuring liabilities during the nine months ended September 30, 2017 , were as follows: (DOLLARS IN THOUSANDS) Employee-Related Costs Other Total Balance at December 31, 2016 $ 3,277 $ — $ 3,277 Additional charges (reversals), net 13,233 950 14,183 Non-cash charges — (950 ) (950 ) Payments (10,267 ) — (10,267 ) Balance at September 30, 2017 $ 6,243 $ — $ 6,243

Senior Notes - 2017 On May 18, 2017, the Company issued $500.0 million face amount of 4.375% Senior Notes ("Senior Notes - 2017") due 2047 at a discount of $ 1.8 million . The Company received proceeds related to the issuance of these Senior Notes - 2017 of $493.9 million which was net of the $1.8 million discount and $4.4 million in underwriting fees (recorded as deferred financing costs). In addition, the Company incurred $0.9 million in legal and professional costs associated with the issuance and such costs were recorded as deferred financing costs. In connection with the debt issuance, the Company entered into pre-issuance hedging transactions that were settled upon issuance of the debt and resulted in a loss of approximately $5.3 million . The discount, deferred financing costs and pre-issuance hedge loss are being amortized as interest expense over the 30 year term of the debt. The Senior Notes - 2017 bear interest at a rate of 4.375% per annum, with interest payable semi-annually on June 1 and December 1 of each year, commencing on December 1, 2017. The Senior Notes - 2017 will mature on June 1, 2047. Upon 30 days’ notice to holders of the Senior Notes - 2017, the Company may redeem the Senior Notes - 2017 for cash in whole, at any time, or in part, from time to time, prior to maturity, at redemption prices that include accrued and unpaid interest and a make-whole premium, as specified in the Indenture governing the Senior Notes - 2017. However, no make-whole premium will be paid for redemptions of the Senior Notes - 2017 on or after December 1, 2046. The Indenture provides for customary events of default and contains certain negative covenants that limit the ability of the Company and its subsidiaries to grant liens on assets, or to enter into sale-leaseback transactions. In addition, subject to certain limitations, in the event of the occurrence of both (1) a change of control of the Company and (2) a downgrade of the Senior Notes - 2017 below investment grade rating by both Moody’s Investors Services, Inc. and Standard & Poor’s Ratings Services within a specified time period, the Company will be required to make an offer to repurchase the Senior Notes - 2017 at a price equal to 101% of the principal amount of the Senior Notes - 2017, plus accrued and unpaid interest to the date of repurchase.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: Uncertain Tax Positions At September 30, 2017 , the Company had $18.9 million of unrecognized tax benefits recorded in Other liabilities and $6.9 million in Other current liabilities. If these unrecognized tax benefits were recognized, the effective tax rate would be affected. At September 30, 2017 , the Company had accrued interest and penalties of $1.7 million classified in Other liabilities and $0.7 million in Other current liabilities. As of September 30, 2017 , the Company’s aggregate provisions for uncertain tax positions, including interest and penalties, was $28.2 million associated with various tax positions asserted in various jurisdictions, none of which is individually material. The Company regularly repatriates a portion of current year earnings from select non–U.S. subsidiaries. No provision is made for additional taxes on undistributed earnings of subsidiary companies that are intended and planned to be indefinitely invested in such subsidiaries. We intend to, and have plans to, reinvest these earnings indefinitely in our foreign subsidiaries to fund local operations and/or capital projects. The Company has ongoing income tax audits and legal proceedings which are at various stages of administrative or judicial review. In addition, the Company has open tax years with various taxing jurisdictions that range primarily from 2007 to 2016 . Based on currently available information, we do not believe the ultimate outcome of any of these tax audits and other tax positions related to open tax years, when finalized, will have a material impact on our financial position. The Company also has other ongoing tax audits and legal proceedings that relate to indirect taxes, such as value-added taxes, sales and use taxes and property taxes, which are discussed in Note 13. Effective Tax Rate The effective tax rate for the three months ended September 30, 2017 was 22.0% compared with 20.8% for the three months ended September 30, 2016 . The quarter-over-quarter increase was largely due to higher repatriation costs partially offset by the impact of the global supply chain hub and mix of earnings as compared to the prior year. The effective tax rate for the nine months ended September 30, 2017 was 20.4% compared with 22.7% for the nine months ended September 30, 2016 . The period-over-period decrease was primarily due to certain non-taxable gains on foreign currency and the impact of adopting the new accounting guidance on the tax effect of stock compensation vesting, a more favorable mix of earnings and the impact of the global supply chain hub, offset by unfavorable repatriation costs as compared to the prior year.

(As discussed in Note 13, the sales value of the recalled products was reserved in the first quarter of 2017). While the Company does not believe that any of the affected raw material was included in its finished products delivered to the customer, as the delivered product included raw material of the same vendor lot that tested positive, the FDA, after being notified by the Company, initiated a recall of all consumer products including raw material from the affected vendor lot due to the potential for product contamination. Net sales are attributed to individual regions based upon the destination of product delivery. Net sales related to the U.S. for the three months ended September 30, 2017 and 2016 were $251 million and $190 million , respectively and for the nine months ended September 30, 2017 and 2016 were $731 million and $555 million , respectively.

Financial Instruments

Investments, All Other Investments [Abstract]
Financial Instruments	Financial Instruments: Fair Value Accounting guidance on fair value measurements specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1–Quoted prices for identical instruments in active markets. • Level 2–Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3–Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable . This hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. We determine the fair value of structured liabilities (where performance is linked to structured interest rates, inflation or currency risks) using the LIBOR swap curve and forward interest and exchange rates at period end. Such instruments are classified as Level 2 based on the observability of significant inputs to the model. We do not have any instruments classified as Level 1 or Level 3, other than those included in pension asset trusts as discussed in Note 14 of our 2016 Form 10-K. These valuations take into consideration our credit risk and our counterparties’ credit risk. The estimated change in the fair value of these instruments due to such changes in our own credit risk (or instrument-specific credit risk) was immaterial as of September 30, 2017 . The amounts recorded in the balance sheet (carrying amount) and the estimated fair values of financial instruments at September 30, 2017 and December 31, 2016 consisted of the following: September 30, 2017 December 31, 2016 (DOLLARS IN THOUSANDS) Carrying Fair Carrying Fair Cash and cash equivalents (1) $ 316,002 $ 316,002 $ 323,992 $ 323,992 Credit facilities and bank overdrafts (2) 9,807 9,807 13,599 13,599 Commercial paper (2) 39,957 39,957 — — Long-term debt: (3) Senior notes - 2007 249,765 297,010 499,676 556,222 Senior notes - 2013 298,594 307,675 297,986 302,376 Euro Senior notes - 2016 582,514 614,498 512,764 546,006 Senior notes - 2017 492,653 497,998 — — (1) The carrying amount of cash and cash equivalents approximates fair value due to the short maturity of those instruments. (2) The carrying amount of our credit facilities, bank overdrafts and commercial paper approximates fair value as the interest rate is reset frequently based on current market rates as well as the short maturity of those instruments. (3) The fair value of our long-term debt was calculated using discounted cash flows applying current interest rates and current credit spreads based on our own credit risk. Derivatives The Company periodically enters into foreign currency forward contracts with the objective of reducing exposure to cash flow volatility associated with our intercompany loans, foreign currency receivables and payables, and anticipated purchases of certain raw materials used in operations. These contracts generally involve the exchange of one currency for a second currency at a future date, have maturities not exceeding twelve months and are with counterparties which are major international financial institutions. During the nine months ended September 30, 2017 and the year ended December 31, 2016 , the Company entered into several forward currency contracts which qualified as net investment hedges, in order to mitigate a portion of our net European investments from foreign currency risk. The effective portions of net investment hedges are recorded in Other comprehensive income (“OCI”) as a component of Foreign currency translation adjustments in the accompanying Consolidated Statement of Comprehensive Income. Realized gains (losses) are deferred in accumulated other comprehensive income ("AOCI") where they will remain until the net investments in our European subsidiaries are divested. The outstanding forward currency contracts have remaining maturities of approximately one year . Fourteen of these forward currency contracts matured during the nine months ended September 30, 2017 . Subsequent to the issuance of the Euro Senior Notes - 2016 during the first quarter of 2016, the Company designated the debt as a hedge of a portion of its net European investments. Accordingly, the change in the value of the debt that is attributable to foreign exchange movements is recorded in OCI as a component of Foreign currency translation adjustments in the accompanying Consolidated Statement of Comprehensive Income. During the nine months ended September 30, 2017 and the year ended December 31, 2016 , the Company entered into several forward currency contracts which qualified as cash flow hedges. The objective of these hedges is to protect against the currency risk associated with forecasted U.S. dollar (USD) denominated raw material purchases made by Euro (EUR) functional currency entities which result from changes in the EUR/USD exchange rate. The effective portions of cash flow hedges are recorded in OCI as a component of gains/(losses) on derivatives qualifying as hedges in the accompanying Consolidated Statement of Comprehensive Income. Realized gains/(losses) in AOCI related to cash flow hedges of raw material purchases are recognized as a component of Cost of goods sold in the accompanying Consolidated Statement of Comprehensive Income in the same period as the related costs are recognized. The Company has entered into interest rate swap agreements that effectively converted the fixed rate on a portion of our long-term borrowings to a variable short-term rate based on the LIBOR plus an interest markup. These swaps are designated as fair value hedges. Amounts recognized in Interest expense were immaterial for the three and nine months ended September 30, 2017 . During the first quarter of 2016, the Company entered into and terminated two Euro interest rate swap agreements to hedge the anticipated issuance of fixed-rate debt. These swaps were designated as cash flow hedges. The effective portions of cash flow hedges are recorded in OCI as a component of Losses on derivatives qualifying as hedges in the accompanying Consolidated Statement of Comprehensive Income. The Company incurred a loss of Euro 2.9 million ( $3.2 million ) due to the termination of these swaps. The loss is being amortized as interest expense over the life of the Euro Senior Notes - 2016. During the fourth quarter of 2016 and the first quarter of 2017, the Company entered into interest rate swap agreements to hedge the anticipated issuance of fixed-rate debt, which are designated as cash flow hedges. The various hedge instruments were settled upon issuance of the debt on May 18, 2017 and resulted in a loss of approximately $5.3 million . As discussed in Note 6, the loss is being amortized as interest expense over the life of the Senior Notes - 2017. The effective portions of cash flow hedges are recorded in OCI as a component of Losses/gains on derivatives qualifying as hedges in the accompanying Consolidated Statement of Comprehensive Income.

The Company expects that approximately $5.4 million (net of tax) of derivative loss included in AOCI at September 30, 2017 , based on current market rates, will be reclassified into earnings within the next 12 months. The majority of this amount will vary due to fluctuations in foreign currency exchange rates.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies: Guarantees and Letters of Credit The Company has various bank guarantees and letters of credit which are available for use to support its ongoing business operations and to satisfy governmental requirements associated with pending litigation in various jurisdictions. At September 30, 2017 , we had total bank guarantees and standby letters of credit of approximately $38.1 million with various financial institutions. Included in the above aggregate amount is a total of $16.3 million in bank guarantees which the Company has posted for certain assessments in Brazil for other diverse income tax and indirect tax disputes related to fiscal years 1998-2011. There were no material amounts utilized under the standby letters of credit as of September 30, 2017 . In order to challenge the assessments in these cases in Brazil, the Company has been required to, and has separately pledged assets, principally property, plant and equipment, to cover assessments in the amount of approximately $15.6 million as of September 30, 2017 . Lines of Credit The Company has various lines of credit which are available to support its ongoing business operations. At September 30, 2017 , we had available lines of credit (in addition to the $950 million of capacity under the Credit Facility discussed in Note 9 of our 2016 Form 10-K) of approximately $75.6 million with various financial institutions. There were no significant amounts drawn down pursuant to these lines of credit as of September 30, 2017 . Litigation The Company assesses contingencies related to litigation and/or other matters to determine the degree of probability and range of possible loss. A loss contingency is accrued in the Company’s consolidated financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highly sensitive and requires judgments about future events. On at least a quarterly basis, the Company reviews contingencies related to litigation to determine the adequacy of accruals. The amount of ultimate loss may differ from these estimates and further events may require the Company to increase or decrease the amounts it has accrued on any matter. Periodically, we assess our insurance coverage for all known claims, where applicable, taking into account aggregate coverage by occurrence, limits of coverage, self-insured retentions and deductibles, historical claims experience and claims experience with our insurance carriers. The liabilities are recorded at management’s best estimate of the probable outcome of the lawsuits and claims, taking into consideration the facts and circumstances of the individual matters as well as past experience on similar matters. At each balance sheet date, the key issues that management assesses are whether it is probable that a loss as to asserted or unasserted claims has been incurred and if so, whether the amount of loss can be reasonably estimated. We record the expected liability with respect to claims in Other liabilities and expected recoveries from our insurance carriers in Other assets. We recognize a receivable when we believe that realization of the insurance receivable is probable under the terms of the insurance policies and our payment experience to date. Environmental Over the past 20 years, various federal and state authorities and private parties have claimed that we are a Potentially Responsible Party (“PRP”) as a generator of waste materials for alleged pollution at a number of waste sites operated by third parties located principally in New Jersey and have sought to recover costs incurred and to be incurred to clean up the sites. We have been identified as a PRP at eight facilities operated by third parties at which investigation and/or remediation activities may be ongoing. We analyze our potential liability on at least a quarterly basis. We accrue for environmental liabilities when they are probable and estimable. We estimate our share of the total future cost for these sites to be less than $5 million . While joint and several liability is authorized under federal and state environmental laws, we believe the amounts we have paid and anticipate paying in the future for clean-up costs and damages at all sites are not material and will not have a material adverse effect on our financial condition, results of operations or liquidity. This assessment is based upon, among other things, the involvement of other PRPs at most of the sites, the status of the proceedings, including various settlement agreements and consent decrees, and the extended time period over which payments will likely be made. There can be no assurance, however, that future events will not require us to materially increase the amounts we anticipate paying for clean-up costs and damages at these sites, and that such increased amounts will not have a material adverse effect on our financial condition, results of operations or cash flows. China Facilities Guangzhou Flavors plant During 2015, the Company was notified by Chinese authorities of compliance issues pertaining to the emission of odors from several of its plants in China. As a result, the Company's Guangzhou Flavors plant in China was temporarily idled in 2015. The Company has made additional capital improvements in odor-abatement equipment at these plants to address these issues and is in the process of building a second Flavors plant in China, which is expected to begin operating in the first quarter of 2019. During the fourth quarter of 2016, the Company was notified that certain governmental authorities have begun to evaluate a change in the zoning of the Guangzhou Flavors plant. The zoning, if changed, would prevent the Company from continuing to manufacture product at the existing plant. The ultimate outcome of any change that the governmental authorities may propose, the timing of such a change and the nature of any compensation arrangements that might be provided to the Company are uncertain. The net book value of the existing plant was approximately $68 million as of September 30, 2017 . Zhejiang Ingredients plant In the first quarter of 2016, the Company received a request from the Chinese government to relocate its Fragrance Ingredients plant in Zhejiang, China. Since then, the Company has been in discussions with the government regarding the timing of the requested relocation and the amount and nature of government compensation to be provided to the Company. The Company expects to conclude discussions with the government in the fourth quarter of 2017. The net book value of the current plant was approximately $25 million as of September 30, 2017 . Based on the current expectations regarding the compensation package, the Company estimates that between $0 - 12 million of the remaining net book value may be subject to accelerated depreciation beginning in the fourth quarter of 2017. The Company expects to relocate approximately half of the facility by the end of 2018 and the remainder of the facility by the end of 2019. Total China Operations The total carrying value of our six existing plants in China ( two of which are currently under construction) was approximately $145 million as of September 30, 2017 . If the Company is required to close a plant, or operate one at significantly reduced production levels on a permanent basis, the Company may be required to record charges that could have a material impact on its consolidated financial results of operations, financial position and cash flows in future periods. Other Contingencies The Company has contingencies involving third parties (such as labor, contract, technology or product-related claims or litigation) as well as government-related items in various jurisdictions in which we operate pertaining to such items as value-added taxes, other indirect taxes, customs and duties and sales and use taxes. It is possible that cash flows or results of operations, in any period, could be materially affected by the unfavorable resolution of one or more of these contingencies. The most significant government-related contingencies exist in Brazil. With regard to the Brazilian matters, we believe we have valid defenses for the underlying positions under dispute; however, in order to pursue these defenses, we are required to, and have provided, bank guarantees and pledged assets in the aggregate amount of $31.9 million . The Brazilian matters take an extended period of time to proceed through the judicial process and there are a limited number of rulings to date. As previously disclosed, in March 2012, ZoomEssence, Inc. filed a complaint against the Company in the U.S. District Court for the District of New Jersey alleging trade secret misappropriation, breach of contract and unjust enrichment in connection with certain spray dry technology disclosed to the Company. ZoomEssence sought an injunction and monetary damages. In November 2014, the Company filed a counterclaim against ZoomEssence alleging trade secret misappropriation, breach of contract, breach of the implied covenant of good faith and fair dealing, unjust enrichment, misappropriation of confidential and proprietary information, common law unfair competition, tortious interference with contractual relations, and conversion. During the second quarter of 2017, the Company and ZoomEssence mutually agreed to settle all claims and counterclaims. The parties agreed to dismiss their claims against one another, with prejudice and without any admission of liability or wrongful conduct, to avoid any further expense and disruption from the litigation. The complaint was dismissed, with prejudice, on July 5, 2017. Under the settlement agreement, the Company made a one-time payment to ZoomEssence of $56 million during the second quarter of 2017 and the parties exchanged full mutual releases. Accordingly, the Company recorded an additional charge of $1 million during the second quarter of 2017. The Company periodically incurs product liability claims based on product that is sold to customers that may be defective or otherwise not in accordance with the customer’s requirements. As previously disclosed, in the first quarter of 2017, the Company was made aware of a claim for product that was subject to a product recall. As of September 30, 2017 , the Company had recorded a total charge of approximately $5.3 million with respect to this claim. In addition to the charge of $1.8 million recorded in the first quarter of 2017, an additional $3.5 million was recorded during the second quarter of 2017. The second quarter charge reflects additional information on specific volumes of affected products, which information became available in the second quarter of 2017. This amount principally represents an accrual for the claim based on management's best estimate of volumes of customer products subject to the recall. Additionally, appropriate reserves have been established for all remaining inventory at the Company's manufacturing site. While it is probable that the Company will incur additional losses related to this claim, the amount of the ultimate claim that will be paid is not currently estimable as the following information is not yet available: details as to the amount of product that will ultimately be returned and the customer’s direct manufacturing and other production costs; costs related to the customer’s recall efforts; costs to dispose of defective product; and other claims that the customer may make. While it is not currently possible to estimate the amount of losses, such losses when recorded will affect income from operations in future individual quarters. The Company does not believe that the ultimate settlement of the claim will have a material impact on its financial condition. Separately, the Company expects to pursue reimbursement of all or a portion of costs, once incurred, from its insurance company and/or the supplier; however, the nature, timing and amount of any such reimbursement cannot be determined at this time. The Company determines estimates of reasonably possible losses or ranges of reasonably possible losses in excess of related accrued liabilities, if any, when it has determined that either a loss is reasonably possible or a loss in excess of accrued amounts is reasonably possible and the amount of losses or range of losses is determinable. For all third party contingencies (including labor, contract, technology, tax, product-related claims and business litigation), the Company currently estimates that the aggregate range of reasonably possible estimable losses in excess of any accrued liabilities is $0 to approximately $23 million . The estimates included in this amount are based on the Company’s analysis of currently available information and, as new information is obtained, these estimates may change. Due to the inherent subjectivity of the assessments and the unpredictability of outcomes of legal proceedings, any amounts accrued or included in this aggregate amount may not represent the ultimate loss to the Company from the matters in question. Thus, the Company’s exposure and ultimate losses may be higher or lower, and possibly significantly so, than the amounts accrued or the range disclosed above. We are also a party to other litigation arising in the ordinary course of our business. We do not expect the outcome of these cases, singly or in the aggregate, to have a material effect on our consolidated financial condition.

Consolidated Financial Statements (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These interim statements and related management’s discussion and analysis should be read in conjunction with the Consolidated Financial Statements and the related notes and management’s discussion and analysis of results of operations, liquidity and capital resources included in our 2016 Annual Report on Form 10-K (“ 2016 Form 10-K”). These interim statements are unaudited. The year-end balance sheet data included in this Form 10-Q was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles in the United States of America. We have historically operated and continue to operate on a 52/53 week fiscal year ending on the Friday closest to the last day of the quarter. For ease of presentation, September 30 and December 31 are used consistently throughout this Form 10-Q and these interim financial statements and related notes to represent the period-end dates. For the 2017 and 2016 quarters, the actual closing dates were September 29, and September 30, respectively. The unaudited interim financial statements include all adjustments (consisting only of normal recurring adjustments) and accruals necessary in the judgment of management for a fair statement of the results for the periods presented. When used herein, the terms “IFF,” the “Company,” “we,” “us” and “our” mean International Flavors & Fragrances Inc. and its consolidated subsidiaries.
Reclassifications and Revisions	Reclassifications and Revisions Certain prior year amounts have been reclassified and revised to conform with current year presentation. The Consolidated Statement of Comprehensive Income has been revised to properly reflect Gain on sales of fixed assets within Operating profit for the three and nine months ending September 30, 2016. These amounts were previously included in Other (income) expense, net. In addition, approximately $5.4 million of expense was recorded during the first quarter of 2017 for a tax assessment relating to prior periods. The Consolidated Statement of Cash Flows has been revised to properly reclassify $5.4 million from Net cash used in financing activities to Net cash provided by operating activities for the nine months ended September 30, 2016. These adjustments were not material to the current and previously-issued financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2017, the Financial Accounting Standards Board (“FASB”) issued amendments to the Derivatives and Hedging guidance which eliminates the requirement to separately measure and present hedge ineffectiveness and aligns the presentation of hedge gains and losses with the underlying hedge item. This guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The amended presentation and disclosure requirements should be applied prospectively while the amendments to cash flow and net investment hedge relationships should be applied on a modified retrospective basis . The Company is currently evaluating the impact this guidance will have on its Consolidated Financial Statements. In May 2017, the FASB issued amendments to the Compensation - Stock Compensation guidance which clarifies changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting. This guidance is effective, and should be applied prospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted. The Company does not expect this guidance to have an impact on its Consolidated Financial Statements as it is not the Company's practice to modify the terms or conditions of a share-based payment award after it has been granted. In March 2017, the FASB issued amendments to the Compensation - Retirement Benefits guidance which requires employers that present a measure of operating income in their statement of income to include only the service cost component of net periodic pension cost and postretirement costs in operating expenses. This guidance is effective, and should be applied retrospectively, for fiscal years beginning after December 15, 2017. Early adoption is permitted as of the beginning of an annual period. The Company expects the impact that this guidance will have on its Consolidated Statement of Comprehensive Income will be an increase in operating expenses of approximately $15 million and $30 million for the fiscal years 2016 and 2017, respectively. There will be no impact to Net income in either period. In January 2017, the FASB issued amendments to the Business Combination guidance which clarifies the definition of a business in order to assist companies when evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance will be effective prospectively for annual and interim periods beginning after December 15, 2017. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and on accounting for future acquisitions. In January 2017, the FASB issued an amendment to the Goodwill Impairment guidance which eliminates Step 2 from the goodwill impairment test. This guidance will be effective for fiscal years beginning after December 15, 2019. Early adoption is permitted and the Company has elected to early adopt this guidance and will apply it to its existing annual impairment review policy for fiscal year 2017. The Company does not expect this adoption to have an impact on its consolidated financial statements. In October 2016, the FASB issued authoritative guidance which allows for the immediate recognition of current and deferred income tax impact on intra-entity asset transfers, excluding inventory. This guidance will be effective for fiscal years beginning after December 15, 2017. The Company adopted this guidance in the first quarter of fiscal year 2017 and accordingly, recorded a cumulative-effect adjustment to Retained earnings that reduced Other assets and adjusted Deferred income taxes by a net amount of approximately $33 million . In August 2016, the FASB issued authoritative guidance which requires changes to the classification of certain activities within the statement of cash flows. This guidance will be effective for annual and interim periods beginning after December 15, 2017. Early adoption will be permitted for all entities. The Company does not expect this adoption to have a significant impact on its Consolidated Statement of Cash Flows. In March 2016, the FASB issued authoritative guidance which requires changes to several aspects of the accounting for share-based payment transactions, including the treatment of income tax consequences, classification of awards as either equity or liabilities, and classification of certain items on the statement of cash flows. This guidance was effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard during the first quarter of 2017. The standard requires that employee taxes paid when an employer withholds shares be presented in the Consolidated Statement of Cash Flows as a financing activity instead of an operating activity. The Company adopted this change retrospectively. The adoption resulted in a $11.5 million and $13.3 million reclassification from Net cash provided by operating activities to Net cash provided by financing activities on the Consolidated Statement of Cash Flows as of September 30, 2017 and 2016, respectively. In addition, the standard requires that excess tax benefits presented in the Consolidated Statement of Cash Flows be classified as an operating activity instead of a financing activity. The Company adopted this change retrospectively. The adoption resulted in a $3.2 million and $4.5 million reclassification from Net cash provided by financing activities to Net cash provided by operating activities on the Consolidated Statement of Cash Flows as of September 30, 2017 and 2016, respectively. The standard also requires all excess tax benefits/deficiencies be recognized as income tax expense/benefit in the Consolidated Statement of Comprehensive Income. This guidance has been applied prospectively. This change resulted in a $3.2 million benefit to income tax expense for the period ended September 30, 2017 . The 2016 period included a $1.2 million benefit to equity, which has not been retrospectively adjusted. The full year 2016 benefit to equity was $5.3 million . Additionally, the standard allows the Company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to be forfeited or account for forfeitures as they occur. The Company has elected to continue to account for forfeitures using an estimate of awards expected to be forfeited. In February 2016, the FASB issued authoritative guidance which requires changes to the accounting for leases. The new guidance establishes a new lease accounting model, that requires entities to record assets and liabilities related to leases on the balance sheet for certain types of leases. The guidance will be effective for annual and interim periods beginning after December 15, 2018. Early adoption will be permitted for all entities. The Company expects the adoption of this guidance will result in significant increases to assets and liabilities on its Consolidated Balance Sheet and is still evaluating the impact on its Consolidated Statement of Comprehensive Income. In May 2014, the FASB issued authoritative guidance that provides for a comprehensive model to be used in accounting for revenue arising from contracts with customers. Under this standard, revenue will be recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. This guidance is applicable to all entities and is effective for annual and interim periods beginning after December 15, 2017. Companies have the option to apply the new guidance under a retrospective approach to each prior reporting period presented or a modified retrospective approach with the cumulative effect of initially applying the new guidance recognized at the date of initial application within the Consolidated Balance Sheet. The Company has determined that it will adopt this guidance using the modified retrospective approach. The Company is evaluating the impact of the new standard, including updates to the standard that were issued by the FASB. In particular, the Company has reviewed the nature of its larger customer relationships and is in the process of reviewing the nature of potential regional variations in all aspects of its customer base regardless of size. Based on the work performed to date, the Company expects to conduct further review and analysis of certain areas that may lead to changes in the manner in which the Company recognizes revenue, including the customized nature of the product, consignment arrangements, rebates, upfront costs, shipping terms and documentation other than formal contracts. As a result, the financial statement impact has not yet been determined. The Company continues to evaluate the potential impact of this standard on its consolidated financial statements and related disclosures.
Accounts Receivable	Accounts Receivable The Company sells certain accounts receivable on a non-recourse basis to unrelated financial institutions under “factoring” agreements that are sponsored, solely and individually, by certain customers. The Company accounts for these transactions as sales of receivables, removes the receivables sold from its financial statements, and records cash proceeds when received by the Company. The beneficial impact on cash provided by operations from participating in these programs increased approximately $12.1 million for the nine months ended September 30, 2017 compared to an increase of approximately $25.8 million for the nine months ended September 30, 2016 . The cost of participating in these programs was immaterial to our results in all periods.
