Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and New Accounting Pronouncements	Basis of Presentation and New Accounting Pronouncements Basis of Presentation The unaudited condensed consolidated financial statements and notes thereto of Rayonier Advanced Materials Inc. (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, these financial statements and notes reflect all adjustments (all of which are normal recurring adjustments) necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. These statements and notes should be read in conjunction with the financial statements and supplementary data included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , as filed with the SEC on March 1, 2019. Recently Adopted Accounting Pronouncements Leases The Company adopted Accounting Standards Update 2016-02, Leases , as amended, as of January 1, 2019. The standard requires the recognition of right of use (“ROU”) assets and lease liabilities to be reported on the balance sheet, but did not change the manner in which expenses are recorded in the income statement. The Company has adopted the lease guidance using the cumulative effect adjustment approach, which requires prospective application at the adoption date and elected certain practical expedients permitted under the transition guidance. The practical expedients allow for the carry forward of the historical lease classification of existing leases and eliminates the need to reassess any lease classification of expired leases and initial direct costs. The Company also elected the short-term lease practical expedient. The Company does not record ROU assets or lease liabilities for short-term leases. In addition, the Company utilized the portfolio approach to group leases with similar characteristics and did not use hindsight to determine the lease term. For leases that include other costs, such as maintenance and other services, in addition to lease cost, the Company is separating lease and non-lease components when determining the ROU assets and lease liabilities. Adoption of the new standard resulted in the recording of a ROU lease assets and lease liability of $10 million and $11 million , respectively, and the reversal of deferred rent liability balances. See Note 4 — Leases for additional information. Subsequent Events Events and transactions subsequent to the balance sheet date have been evaluated for potential recognition and disclosure through May 9, 2019 , the date these financial statements were available to be issued. The following subsequent events warranting disclosure were identified. On April 12, 2019, the Company’s Board of Directors declared a second quarter cash dividend of $2.00 per share of mandatory convertible preferred stock. The preferred stock dividend will be paid on May 15, 2019 to mandatory convertible preferred stockholders of record as of May 1, 2019.

Environmental Remediation Obligations [Abstract]
Liabilities for Disposed Operations	Liabilities for Disposed Operations An analysis of the liabilities for disposed operations for the three months ended March 30, 2019 is as follows: Balance, December 31, 2018 $ 160,654 Increase in liabilities 271 Payments (423 ) Foreign currency adjustments 343 Balance, March 30, 2019 160,845 Less: Current portion (11,368 ) Long-term liabilities for disposed operations $ 149,477 In addition to the estimated liabilities, the Company is subject to the risk of reasonably possible additional liabilities in excess of the established reserves due to potential changes in circumstances and future events, including, without limitation, changes to current laws and regulations; changes in governmental agency personnel, direction, philosophy and/or enforcement policies; developments in remediation technologies; increases in the cost of remediation, operation, maintenance and monitoring of its disposed operations sites; changes in the volume, nature or extent of contamination to be remediated or monitoring to be undertaken; the outcome of negotiations with governmental agencies and non-governmental parties; and changes in accounting rules or interpretations. Based on information available as of March 30, 2019 , the Company estimates this exposure could range up to approximately $69 million , although no assurances can be given that this amount will not be exceeded given the factors described above. These potential additional costs are attributable to several sites and other applicable liabilities. Further, this estimate excludes reasonably possible liabilities which are not currently estimable primarily due to the factors discussed above. Subject to the previous paragraph, the Company believes established liabilities are sufficient for probable costs expected to be incurred over the next 20 years with respect to its disposed operations. However, no assurances are given they will be sufficient for the reasons described above, and additional liabilities could have a material adverse effect on the Company’s financial position, results of operations and cash flows.

Derivatives Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives Instruments	Derivative Instruments The Company’s earnings and cash flows are subject to fluctuations due to changes in interest rates and foreign currency exchange rates. The Company allows for the use of derivative financial instruments to manage interest rate and foreign currency exchange rate exposure, but does not allow derivatives to be used for speculative purposes. All derivative instruments are recognized on the consolidated balance sheets at their fair value and are either designated as a hedge of a forecasted transaction or undesignated. Changes in the fair value of a derivative designated as a hedge are recorded in other comprehensive income until earnings are affected by the hedged transaction and are then reported in current earnings. Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current earnings. Interest Rate Risk The Company’s primary debt obligations utilize variable-rate LIBOR, exposing the Company to variability in interest payments due to changes in interest rates. The Company entered into interest rate swap agreements to reduce the volatility of financing costs, achieve a desired proportion of fixed-rate versus floating-rate debt and to hedge the variability in cash flows attributable to interest rate risks caused by changes in the LIBOR benchmark. The Company designated the swaps as cash flow hedges and is assessing their effectiveness using the hypothetical derivative method in conjunction with regression. Effective gains and losses, deferred to accumulated other comprehensive income (loss) (“AOCI”), are reclassified into earnings over the life of the associated hedge. Foreign Currency Exchange Rate Risk Foreign currency fluctuations affect investments in foreign subsidiaries and foreign currency cash flows related to third party purchases, product shipments, and foreign-denominated debt. The Company is also exposed to the translation of foreign currency earnings to the U.S. dollar. Management uses foreign currency forward contracts to selectively hedge its foreign currency cash flow exposure and manage risk associated with changes in currency exchange rates. The Company’s principal foreign currency exposure is to the Canadian dollar, and to a lesser extent, the euro. The notional amounts of outstanding derivative instruments as of March 30, 2019 and December 31, 2018 are presented below. March 30, 2019 December 31, 2018 Interest rate swaps (a) $ 200,000 $ 200,000 Foreign exchange forward contracts (b) $ 371,828 $ 388,930 Foreign exchange forward contracts (c) $ 94,358 $ 125,979 (a) Maturity date of December 2020 (b) Various maturity dates through March 2020 (c) Various maturity dates in 2020, 2022 and 2028 The fair values of derivative instruments included in the consolidated balance sheet as of March 30, 2019 and December 31, 2018 are provided in the below table.

Fair Value Measurements	Fair Value Measurements The following table presents the carrying amount, estimated fair values and categorization under the fair value hierarchy for financial instruments held by the Company at March 30, 2019 and December 31, 2018 , using market information and what management believes to be appropriate valuation methodologies: March 30, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Assets: Level 1 Level 2 Level 1 Level 2 Cash and cash equivalents $ 67,991 $ 67,991 $ — $ 108,966 $ 108,966 $ — Interest rate swaps (a) 1,150 — 1,150 2,131 — 2,131 Foreign currency forward contracts (a) 635 — 635 7 — 7 Liabilities (b): Foreign currency forward contracts (a) 7,375 — 7,375 19,873 — 19,873 Fixed-rate long-term debt 585,649 — 563,800 585,824 — 541,267 Variable-rate long-term debt 634,232 — 637,500 599,221 — 602,652 (a) These items represent derivative instruments. (b) Liabilities exclude finance lease obligation. The Company uses the following methods and assumptions in estimating the fair value of its financial instruments: Cash and cash equivalents — The carrying amount is equal to fair market value. Derivative instruments — The fair value is calculated based on standard valuation models using quoted prices and market observable data of similar instruments. The interest rate derivatives are based on the LIBOR swap rate, which is observable at commonly quoted intervals for the full term of the swap and therefore is considered Level 2. The foreign currency derivatives are contracts to buy foreign currency at a fixed rate on a specified future date. The foreign exchange rate is observable for the full term of the swap and is therefore considered Level 2. See Note 8 — Derivative Instruments for additional information related to the derivative instruments. Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. The variable rate debt adjusts with changes in the market rate, therefore the carrying value approximates fair value.

Net proceeds were $167 million after deducting underwriting discounts, commissions and expenses. Each share of the Preferred Stock will automatically convert into shares of common stock, subject to anti-dilution and other adjustments, on the mandatory conversion date, which is expected to be August 15, 2019. The number of shares of common stock issuable on conversion will be determined based on the volume-weighted average price of the Company’s common stock over a 20 trading day period immediately prior to the mandatory conversion date (“Applicable Market Value”). If the Applicable Market Value for our common stock is greater than $15.17 or less than $12.91 , the conversion rate per share of Preferred Stock will be 6.5923 or 7.7459 , respectively. If the Applicable Market Value is between $15.17 and $12.91 , the conversion rate per share of Preferred Stock will be between 6.5923 and 7.7459 . Subject to certain restrictions, at any time prior to August 15, 2019, holders of the Preferred Stock may elect to convert all or a portion of their shares into common stock at the minimum conversion rate of 6.5923 shares of common stock per share of Preferred Stock, subject to adjustment. Preferred Stock holders have no voting rights unless dividends on the Preferred Stock have not been declared and paid for six or more dividend periods. In those circumstances, holders will be entitled to vote for the election of a total of two additional members of the Company’s Board of Directors. Dividends on the Preferred Stock are payable on a cumulative basis if and when they are declared by our Board of Directors. If declared, dividends will be paid at an annual rate of 8.00% of the liquidation preference of $100 per share. Dividend payment dates are February 15, May 15, August 15 and November 15 of each year, through August 15, 2019. Dividends may be paid in cash or, subject to certain limitations, in shares of common stock or any combination of cash and shares of common stock. The terms of the Preferred Stock provide that, unless full cumulative dividends have been paid or set aside for payment on all outstanding Preferred Stock for all prior dividend periods, no dividends may be declared or paid on common stock. Common Stock Buyback On January 29, 2018, the Board of Directors authorized a share buyback program pursuant to which the Company may, from time to time, purchase shares of its common stock with an aggregate purchase price of up to $100 million . During the three months ended March 30, 2019 , the Company did not repurchase any common shares under this buyback program. As of March 30, 2019, there was approximately $60 million of share repurchase authorization remaining under the program.

Incentive Stock Plans	Incentive Stock Plans The Company’s total stock based compensation cost for the three months ended March 30, 2019 and March 31, 2018 was $4 million and $2 million , respectively. The Company made new grants of restricted stock units and performance-based stock units to certain employees during the first three months of 2019 . The 2019 restricted stock unit awards vest over three years. The 2019 performance-based stock unit awards are measured against an internal return on invested capital target. Depending on performance against the target, the awards will pay out in common stock amounts between 0 and 200 percent of the performance-based stock units awarded. The total number of common stock awards granted will be adjusted up or down 25 percent , for certain participants, based on stock price performance relative to a peer group over the term of the plan, which could result in a final common stock issuance of 0 to 250 percent of the performance-based stock units awarded. In March 2019 , the performance-based share units granted in 2016 were settled at an average of 246 percent of the performance-based stock units awarded, resulting in the issuance of 923,211 shares of common stock.

Segment Information	Segment Information The Company has currently divided its operations into five reportable segments: High Purity Cellulose, Forest Products, Pulp, Paper and Corporate. The Corporate operations consist primarily of senior management, accounting, information systems, human resources, treasury, tax and legal administrative functions that provide support services to the operating business units. The Company does not currently allocate the cost of maintaining these support functions to its operating units. The Company evaluates the performance of its segments based on operating income. Intersegment sales consist primarily of wood chips sales from Forest Products to High Purity Cellulose, Pulp and Paper segments and high-yield pulp sales from Pulp to Paper. Intersegment sales prices are at rates that approximate market. Net sales, disaggregated by product-line, was comprised of the following: Three Months Ended March 30, 2019 March 31, 2018 High Purity Cellulose Cellulose Specialties $ 192,104 $ 209,127 Commodity Products 73,956 42,747 Other sales (a) 19,949 30,509 Total High Purity Cellulose 286,009 282,383 Forest Products Lumber 57,352 78,380 Other sales (b) 17,827 20,806 Total Forest Products 75,179 99,186 Pulp High-yield pulp 69,679 85,155 Paper Paperboard 47,337 47,791 Newsprint 22,636 27,516 Total Paper 69,973 75,307 Eliminations (18,060 ) (20,039 ) Total net sales $ 482,780 $ 521,992 (a) Other sales include sales of electricity, resins, lignin and other by-products to third-parties (b) Other sales include sales of logs, wood chips and other by-products to other segments and third-parties Operating income (loss) by segment was comprised of the following: Three Months Ended March 30, 2019 March 31, 2018 High Purity Cellulose $ (2,793 ) $ 21,311 Forest Products (5,248 ) 10,637 Pulp 10,422 22,711 Paper (1,765 ) 2,926 Corporate (19,085 ) (11,328 ) Total operating income (loss) $ (18,469 ) $ 46,257 Identifiable assets by segment were as follows: March 30, 2019 December 31, 2018 High Purity Cellulose $ 1,616,441 $ 1,643,092 Forest Products 199,481 166,801 Pulp 102,655 103,308 Paper 245,059 240,427 Corporate 491,775 525,458 Total identifiable assets $ 2,655,411 $ 2,679,086

The changes in the future minimum payments under these obligations are presented as of March 30, 2019 . The payment amounts are estimates and may vary based on changes in actual price and volumes terms. Purchase Obligations Remainder of 2019 $ 148 2020 1,557 2021 1,335 2022 1,150 2023 676 Thereafter 5,081 Total $ 9,947 Contingencies The Company is engaged in various legal and regulatory actions and proceedings, and has been named as a defendant in various lawsuits and claims arising in the ordinary course of its business. While the Company has procured reasonable and customary insurance covering risks normally occurring in connection with its businesses, the Company has in certain cases retained some risk through the operation of self-insurance, primarily in the areas of workers’ compensation, property insurance and general liability. These other lawsuits and claims, either individually or in aggregate, are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows. As of March 30, 2019 , collective bargaining agreements covering less than 25 unionized employees in Canada had expired. The Fernandina mill collective bargaining agreement expires in the second quarter of 2019 and is currently in negotiations. In all cases, the parties have continued to work under the terms of the expired contracts while negotiations continue. While there can be no assurances, the Company expects to reach agreements with its unions. However, a work stoppage could have a material adverse effect on its business, results of operations and financial condition. Guarantees and Other The Company provides financial guarantees as required by creditors, insurance programs and various governmental agencies. As of March 30, 2019 , the Company had net exposure of $37 million from various standby letters of credit, primarily for financial assurance relating to environmental remediation, credit support for natural gas and electricity purchases, and guarantees related to foreign retirement plan obligations. These standby letters of credit represent a contingent liability. The Company would only be liable upon its default on the related payment obligations. The letters of credit have various expiration dates and will be renewed as required. The Company had surety bonds of $84 million as of March 30, 2019 , primarily to comply with financial assurance requirements relating to environmental remediation and post closure care, to provide collateral for the Company’s workers’ compensation program, and to guarantee taxes and duties for products shipped internationally. These surety bonds expire at various dates and are expected to be renewed annually as required. LignoTech Florida, a venture in which the Company owns 45 percent and its venture partner Borregaard ASA owns 55 percent , entered into a construction contract to build its lignin manufacturing facility and financing agreements to fund the construction of the facility, which was completed in the second quarter of 2018. The Company is a guarantor under both the construction and financing agreements. In the event of default, the Company expects it would only be liable for its proportional share as a result of an agreement with its venture partner. The remaining guarantee related to LignoTech Florida at March 30, 2019 was $36 million . The Company has not recorded any liabilities for these financial guarantees in its consolidated balance sheets, either because the Company has recorded the underlying liability associated with the guarantee or the guarantee is dependent on the Company’s own performance and, therefore, is not subject to the measurement requirements or because the Company has calculated the estimated fair value of the guarantee and determined it to be immaterial based upon the current facts and circumstances that would trigger a payment obligation. It is not possible to determine the maximum potential amount of the liability under these potential obligations due to the unique set of facts and circumstances likely to be involved with each provision.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements and notes thereto of Rayonier Advanced Materials Inc. (the “Company”) have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, these financial statements and notes reflect all adjustments (all of which are normal recurring adjustments) necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. These statements and notes should be read in conjunction with the financial statements and supplementary data included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , as filed with the SEC on March 1, 2019.
New or Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Leases The Company adopted Accounting Standards Update 2016-02, Leases , as amended, as of January 1, 2019. The standard requires the recognition of right of use (“ROU”) assets and lease liabilities to be reported on the balance sheet, but did not change the manner in which expenses are recorded in the income statement. The Company has adopted the lease guidance using the cumulative effect adjustment approach, which requires prospective application at the adoption date and elected certain practical expedients permitted under the transition guidance. The practical expedients allow for the carry forward of the historical lease classification of existing leases and eliminates the need to reassess any lease classification of expired leases and initial direct costs. The Company also elected the short-term lease practical expedient. The Company does not record ROU assets or lease liabilities for short-term leases. In addition, the Company utilized the portfolio approach to group leases with similar characteristics and did not use hindsight to determine the lease term. For leases that include other costs, such as maintenance and other services, in addition to lease cost, the Company is separating lease and non-lease components when determining the ROU assets and lease liabilities. Adoption of the new standard resulted in the recording of a ROU lease assets and lease liability of $10 million and $11 million , respectively, and the reversal of deferred rent liability balances. See Note 4 — Leases for additional information.
Fair Value Measurements	The Company uses the following methods and assumptions in estimating the fair value of its financial instruments: Cash and cash equivalents — The carrying amount is equal to fair market value. Derivative instruments — The fair value is calculated based on standard valuation models using quoted prices and market observable data of similar instruments. The interest rate derivatives are based on the LIBOR swap rate, which is observable at commonly quoted intervals for the full term of the swap and therefore is considered Level 2. The foreign currency derivatives are contracts to buy foreign currency at a fixed rate on a specified future date. The foreign exchange rate is observable for the full term of the swap and is therefore considered Level 2. See Note 8 — Derivative Instruments for additional information related to the derivative instruments. Debt — The fair value of fixed rate debt is based upon quoted market prices for debt with similar terms and maturities. The variable rate debt adjusts with changes in the market rate, therefore the carrying value approximates fair value.
