Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation
	GENERAL
	Clearwater Paper manufactures quality consumer tissue, away-from-home tissue, parent roll tissue, bleached paperboard and pulp at manufacturing facilities across the nation. The company is a premier supplier of private label tissue to major retailers and wholesale distributors, including grocery, drug, mass merchants and discount stores. In addition, the company produces bleached paperboard used by quality-conscious printers and packaging converters.
	On December 30, 2014, we sold our specialty business and mills to a private buyer for $108 million in cash, net of sale related expenses and adjustments. The specialty business and mills' production consisted predominantly of machine-glazed tissue and also included parent rolls and other specialty tissue products such as absorbent materials and dark-hued napkins. The sale included five of our former subsidiaries with facilities located at East Hartford, Connecticut; Menominee, Michigan; Gouverneur, New York; St. Catharines, Ontario; and Wiggins, Mississippi.
	On February 17, 2014, we announced the permanent and immediate closure of our Long Island, New York, tissue converting and distribution facility. As of March 31, 2015, we have incurred $19.4 million of costs associated with the closure, of which $0.6 million was incurred during the first quarter of 2015.
	FINANCIAL STATEMENT PREPARATION AND PRESENTATION
	The accompanying Consolidated Balance Sheets at March 31, 2015 and December 31, 2014, the related Consolidated Statements of Operations and Comprehensive Income for the three months ended March 31, 2015 and 2014, and the Consolidated Statements of Cash Flows for the three months ended March 31, 2015 and 2014, have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP. We believe that all adjustments necessary for a fair statement of the results of the interim periods presented have been included. The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the full year.
	This Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the Securities and Exchange Commission, or SEC, on February 26, 2015.
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	SIGNIFICANT ESTIMATES
	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, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Significant areas requiring the use of estimates and measurement of uncertainty include determination of net realizable value for deferred tax assets, uncertain tax positions, assessment of impairment of long-lived assets, goodwill and intangibles, assessment of environmental matters, equity-based compensation and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions.
	SHORT-TERM INVESTMENTS AND RESTRICTED CASH
	Our short-term investments are invested primarily in demand deposits, which have very short maturity periods, and therefore earn an interest rate commensurate with low-risk instruments. We do not attempt to hedge our exposure to interest rate risk for our short-term investments. Our restricted cash in which the underlying instrument has a term of greater than twelve months from the balance sheet date is classified as non-current and is included in “Other assets, net” on our Consolidated Balance Sheet. As of both March 31, 2015 and December 31, 2014, we had $1.5 million of restricted cash classified as current and $2.3 million of restricted cash classified as non-current and included in "Other assets, net" on our Consolidated Balance Sheets.
	TRADE ACCOUNTS RECEIVABLE
	Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. The allowance for doubtful accounts is our best estimate of the losses we expect will result from the inability of our customers to make required payments. We generally determine the allowance based on a combination of actual historical write-off experience and an analysis of specific customer accounts. As of March 31, 2015 and December 31, 2014, we had allowances for doubtful accounts of $1.4 million.
	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment are stated at cost, including any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Assets we acquire through business combinations have estimated lives that are typically shorter than the assets we construct or buy new. Accumulated depreciation totaled $1,469.8 million and $1,450.1 million at March 31, 2015 and December 31, 2014, respectively.
	Consistent with authoritative guidance, we assess the carrying amount of long-lived assets with definite lives that are held-for-use and evaluate them for recoverability whenever events or changes in circumstances indicate that we may be unable to recover the carrying amount of the assets. During the first quarter of 2014, we permanently closed our Long Island tissue converting and distribution facility. As a result of this closure, we considered an outside third party's appraisal in assessing the recoverability of the facility's long-lived plant and equipment based on available market data for comparable assets sold through private party transactions. Based on this assessment, we determined the carrying amounts of certain long-lived plant and equipment related to the Long Island facility exceeded their fair value. As a result, we recorded a $3.0 million non-cash impairment charge to our accompanying Consolidated Statement of Operations for the three months ended March 31, 2014. There were no other such events or changes in circumstances that impacted our remaining long-lived assets.
	STOCKHOLDERS’ EQUITY
	On December 15, 2014, we announced that our Board of Directors had approved a new stock repurchase program authorizing the repurchase of up to $100 million of our common stock. The repurchase program authorizes purchases of our common stock from time to time through open market purchases, negotiated transactions or other means, including accelerated stock repurchases and 10b5-1 trading plans in accordance with applicable securities laws and other restrictions. We have no obligation to repurchase stock under this program and may suspend or terminate the program at any time. During the first quarter of 2015, we repurchased 599,495 shares of our outstanding common stock at an average price of $61.97 per share. As of March 31, 2015, we had up to $62.9 million of authorization remaining pursuant to this stock repurchase program.
	On February 5, 2014, we announced that our Board of Directors had approved a stock repurchase program authorizing the repurchase of up to $100 million of our common stock. We completed that program during the third quarter of 2014. In total, we repurchased 1,574,748 shares of our outstanding common stock at an average price of $63.50 per share under that program.
	DERIVATIVES
	We had no activity during the three months ended March 31, 2015 and 2014 that required hedge or derivative accounting treatment. However, to help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas requirements for our manufacturing facilities. As of March 31, 2015, these contracts covered approximately 53% of our expected average monthly natural gas requirements for the remainder of 2015. Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.
	EMPLOYEES
	Unions represent hourly employees at six of our manufacturing sites. There are no collective bargaining agreements due to expire in 2015. The hourly union labor contracts that had expired as set forth on page 6 of our Annual Report on Form 10-K for the year ended December 31, 2014 were ratified during the first quarter of 2015.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted and New Accounting Standards	Recently Adopted and New Accounting Standards
	In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, 2014-09, Revenue from Contracts with Customers. The core principle of the new standard is for companies to recognize revenue in a manner that depicts the transfer of goods or services to customers in amounts that reflect the consideration, or payment, to which the company expects to be entitled in exchange for those goods or services. The standard will also result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, such as service revenue and contract modifications, and clarify guidance for multiple-element arrangements. This standard is effective for fiscal years and interim periods within those years beginning after December 15, 2016, with early adoption prohibited. On April 1, 2015, the FASB proposed deferring the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date. The FASB also proposed permitting early adoption of the standard, but not before the original effective date of December 15, 2016. The standard may be applied under either a retrospective or cumulative effect adoption method. We are currently evaluating the impact this guidance will have on our consolidated financial statements.
	In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred asset. It is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. The adoption of this guidance is not expected to have a significant effect on our consolidated financial statements.
	We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.

			$	45,476	$	(20,520	)	$	24,956
	As a result of the closure of our Long Island tissue converting and distribution facility, we performed an assessment of the recoverability of our intangible assets by utilizing the income approach, which discounts projected future cash flows based on management’s expectations of the current and future operating environment. It was determined that the carrying amounts of certain trade names and trademarks related to the Long Island facility were exceeding their fair value. As a result, in the first quarter of 2014 we recorded a $1.3 million non-cash impairment charge in our accompanying Consolidated Statement of Operations. There were no other such events or changes in circumstances that impacted our remaining definite-lived intangible assets.

Taxes

Income Tax Disclosure [Abstract]
Taxes	Income Taxes
	Consistent with authoritative guidance, our estimated annual effective tax rate is used to allocate our expected annual income tax provision to interim periods. The rate is the ratio of our estimated annual income tax provision to estimated pre-tax ordinary income and excludes "discrete items," which are significant, unusual or infrequent items reported separately, net of their related tax effect. The estimated annual effective tax rate is applied to the current interim period’s ordinary income to determine the income tax provision allocated to the interim period. The income tax effects of discrete items are then determined separately and recognized in the interim period in which the income or expense items arise.
	For the three months ended March 31, 2015 and 2014, the effective tax rates attributable to continuing operations were as follows:
		Three Months Ended March 31,
		2015		2014
	Statutory federal income tax rate	35	%	35	%
	State taxes, net of credits	2.3		2
	Change in valuation allowances	1		4.2
	Federal manufacturing deduction	(3.3	)	(2.0	)
	Change in uncertain tax positions	(13.4	)	—
	Interest accrued on uncertain tax positions	0.1		0.2
	Federal credits and audit adjustments	(0.4	)	(4.4	)
	State rate adjustments	—		(0.2	)
	Return to provision adjustments	1.4		0.9
	Other	0.1		0.7
	Effective tax rate	22.8	%	36.4	%
	Our estimated annual effective tax rate for the first quarter of 2015 is approximately 35%, compared with approximately 36% during the comparable interim period in 2014. The reduced rate is a result of an additional benefit from the federal manufacturing deduction and state income tax rates.
	During the quarter ended March 31, 2015, the company reduced the reserve for uncertain tax positions due to statute expirations related to certain federal tax credits of $1.0 million. Overall, the reserve for uncertain tax positions decreased from approximately $2.7 million to $1.7 million.

	SENIOR NOTES
	On July 29, 2014, we issued $300 million aggregate principal amount of senior notes, which we refer to as the 2014 Notes. The 2014 Notes mature on February 1, 2025, have an interest rate of 5.375% and were issued at their face value.
	The 2014 Notes are guaranteed by all of our direct and indirect subsidiaries. The 2014 Notes will also be guaranteed by each of our future direct and indirect subsidiaries that do not constitute an immaterial subsidiary under the indenture governing the 2014 Notes. The 2014 Notes are equal in right of payment with all other existing and future unsecured senior indebtedness and are senior in right of payment to any future subordinated indebtedness. The 2014 Notes are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our secured revolving credit facility, which is secured by certain of our accounts receivable, inventory and cash. The terms of the 2014 Notes limit our ability and the ability of any restricted subsidiaries to incur certain liens, engage in sale and leaseback transactions and consolidate, merge with, or convey, transfer or lease substantially all of our or their assets to another person.
	On January 23, 2013, we issued $275 million aggregate principal amount of senior notes, which we refer to as the 2013 Notes. The 2013 Notes mature on February 1, 2023, have an interest rate of 4.5% and were issued at their face value.
	The 2013 Notes are guaranteed by all of our direct and indirect subsidiaries, and will also be guaranteed by each of our future direct and indirect subsidiaries that we do not designate as an unrestricted subsidiary under the indenture governing these notes. The 2013 Notes are equal in right of payment with all other existing and future unsecured senior indebtedness and are senior in right of payment to any future subordinated indebtedness. In addition, they are effectively subordinated to all of our existing and future secured indebtedness, including borrowings under our secured revolving credit facility, which is secured by certain of our accounts receivable, inventory and cash. The terms of the notes limit our ability and the ability of any restricted subsidiaries to borrow money; pay dividends; redeem or repurchase capital stock; make investments; sell assets; create restrictions on the payment of dividends or other amounts to us from any restricted subsidiaries; enter into transactions with affiliates; enter into sale and lease back transactions; create liens; and consolidate, merge or sell all or substantially all of our or their assets.
	REVOLVING CREDIT FACILITY
	On November 26, 2008, we entered into a $125 million senior secured revolving credit facility with certain financial institutions. The amount available to us under the revolving credit facility is based on the lesser of 85% of our eligible accounts receivable plus approximately 65% of our eligible inventory, or $125 million. The revolving credit facility has been subsequently amended and expires on September 30, 2016.
	As of March 31, 2015, there were no borrowings outstanding under the credit facility, but $7.2 million of the credit facility was being used to support outstanding standby letters of credit. Loans under the credit facility bear interest (i) for LIBOR loans, LIBOR plus between 1.75% and 2.25% and (ii) for base rate loans, a per annum rate equal to the greater of (a) the prime rate for such day; (b) the federal funds effective rate for such day, plus 0.50%; or (c) LIBOR for a 30-day interest period as determined on such day, plus between 1.25% and 1.75%. The percentage margin on all loans is based on our fixed charge coverage ratio for the most recent four quarters. As of March 31, 2015, we would have been permitted to draw an additional $117.8 million under the credit facility at LIBOR plus 1.75%, or base rate plus 1.25%.
	A minimum fixed charge coverage ratio is the only financial covenant requirement under our credit facility and is triggered when there are any commitments or obligations outstanding and availability falls below 12.5% or an event of default exists, at which time the minimum fixed charge coverage ratio must be at least 1.0-to-1.0. As of March 31, 2015, the fixed charge coverage ratio for the most recent four quarters was 1.1-to-1.0.
	Our obligations under the revolving credit facility are secured by certain of our accounts receivable, inventory and cash. The terms of the credit facility contain various provisions that limit our discretion in the operations of our business by restricting our ability to, among other things, pay dividends; redeem or repurchase capital stock; create, incur or guarantee certain debt; incur liens on certain properties; make capital expenditures; enter into certain affiliate transactions; enter into certain hedging arrangements; and consolidate with or merge with another entity. The revolving credit facility contains usual and customary affirmative and negative covenants and usual and customary events of default.

	During the three months ended March 31, 2015, we made contributions of $0.1 million to our company-sponsored non-qualified pension plan, and we estimate contributions will total $0.4 million in 2015. We do not anticipate funding our OPEB plans in 2015 except to pay benefit costs as incurred during the year by plan participants.
	During the three months ended March 31, 2015, $1.8 million of net periodic pension and OPEB costs were charged to cost of sales, and $0.8 million were charged to selling, general and administrative expenses in the accompanying Consolidated Statements of Operations. During the three months ended March 31, 2014, $2.3 million of net periodic pension and OPEB costs were charged to "Cost of sales," and $0.6 million were charged to "Selling, general and administrative expenses" in the accompanying Consolidated Statements of Operations.

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share
	Basic earnings per share are based on the weighted average number of shares of common stock outstanding. Diluted earnings per share are based upon the weighted average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method.
	The following table reconciles the number of common shares used in calculating the basic and diluted net earnings per share:
		Three Months Ended March 31,

Equity-Based Compensation	Equity-Based Compensation
	We recognize equity-based compensation expense for all equity-based payment awards made to employees and directors, including restricted stock units, or RSUs, performance shares and stock options, based on estimated fair values.
	EMPLOYEE AWARDS
	Employee equity-based compensation expense was recognized as follows:
		Three Months Ended March 31,
	(In thousands)	2015			2014
	Restricted stock units	$	411		$	445
	Performance shares	879			1,081
	Stock options	349			136
	Total employee equity-based compensation	$	1,639		$	1,662
	As provided for in the Clearwater Paper Corporation 2008 Stock Incentive Plan, the performance measure used to determine the number of performance shares ultimately issued is a comparison of the percentile ranking of our total stockholder return compared to the total stockholder return of a selected peer group. The number of shares actually issued, as a percentage of the amount subject to the performance share award, could range from 0%-200%. On December 31, 2014, the service and performance period for 137,775 outstanding performance shares granted in 2012 ended. Those performance shares were settled and distributed in the first quarter of 2015. The number of shares actually settled, as a percentage of the outstanding amount, was 106.9%. After adjusting for the related minimum tax withholdings, a net 97,921 shares were issued in the first quarter of 2015. The related minimum tax withholdings payment made in the first quarter of 2015 in connection with issued shares was $3.0 million. No restricted stock units vested or were settled during the first quarter of 2015.
	The following table summarizes the number of share-based awards granted under the Clearwater Paper Corporation 2008 Stock Incentive Plan during the three months ended March 31, 2015 and the grant-date fair value of the awards:
		Three Months Ended
		31-Mar-15
		Number of		Average Fair Value of
		Shares Subject to Award		Award Per Share
	Restricted stock units	21,790		$	61.75
	Performance shares	45,627		62.05
	Stock options	136,884		20.82
	DIRECTOR AWARDS
	Annually, each outside member of our Board of Directors receives deferred equity-based awards that are measured in units of our common stock and ultimately settled in cash at the time of payment. Accordingly, the compensation expense associated with these awards is subject to fluctuations each quarter based on mark-to-market adjustments at each reporting period in line with changes in the market price of our common stock. As a result of the mark-to-market adjustment, we recorded a benefit from director equity-based compensation of $0.5 million and compensation expense of $2.8 million for the three months ended March 31, 2015 and 2014, respectively.
	As of March 31, 2015, the liability amounts associated with director equity-based compensation included in "Other long-term obligations" on the accompanying Consolidated Balance Sheet were $13.0 million. At December 31, 2014, liability amounts associated with director equity-based compensation included in "Other long-term obligations" and "Accounts payable and accrued liabilities" totaled $13.5 million and $1.4 million, respectively.

	Long-term debt (Level 1)	575,000		556,625		575,000		558,000
	Accounting guidance establishes a framework for measuring the fair value of financial instruments, providing a hierarchy 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, or “Level 1” measurements, followed by quoted prices of similar assets or observable market data, or “Level 2” measurements, and the lowest priority to unobservable inputs, or “Level 3” measurements.
	The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used should seek to maximize the use of observable inputs and minimize the use of unobservable inputs.

Nature_of_Operations_and_Basis1

Nature of Operations and Basis of Presentation (Policies)	3 Months Ended
	Mar. 31, 2015
Accounting Policies [Abstract]
SIGNIFICANT ESTIMATES	SIGNIFICANT ESTIMATES
	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, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting periods. Significant areas requiring the use of estimates and measurement of uncertainty include determination of net realizable value for deferred tax assets, uncertain tax positions, assessment of impairment of long-lived assets, goodwill and intangibles, assessment of environmental matters, equity-based compensation and pension and postretirement obligation assumptions. Actual results could differ from those estimates and assumptions.
RESTRICTED CASH AND SHORT-TERM INVESTMENTS	SHORT-TERM INVESTMENTS AND RESTRICTED CASH
	Our short-term investments are invested primarily in demand deposits, which have very short maturity periods, and therefore earn an interest rate commensurate with low-risk instruments. We do not attempt to hedge our exposure to interest rate risk for our short-term investments. Our restricted cash in which the underlying instrument has a term of greater than twelve months from the balance sheet date is classified as non-current and is included in “Other assets, net” on our Consolidated Balance Sheet. As of both March 31, 2015 and December 31, 2014, we had $1.5 million of restricted cash classified as current and $2.3 million of restricted cash classified as non-current and included in "Other assets, net" on our Consolidated Balance Sheets.
TRADE ACCOUNTS RECEIVABLE	TRADE ACCOUNTS RECEIVABLE
	Trade accounts receivable are stated at the amount we expect to collect. Trade accounts receivable do not bear interest. The allowance for doubtful accounts is our best estimate of the losses we expect will result from the inability of our customers to make required payments. We generally determine the allowance based on a combination of actual historical write-off experience and an analysis of specific customer accounts. As of March 31, 2015 and December 31, 2014, we had allowances for doubtful accounts of $1.4 million.
PROPERTY, PLANT AND EQUIPMENT	PROPERTY, PLANT AND EQUIPMENT
	Property, plant and equipment are stated at cost, including any interest costs capitalized, less accumulated depreciation. Depreciation of buildings, equipment and other depreciable assets is determined using the straight-line method. Assets we acquire through business combinations have estimated lives that are typically shorter than the assets we construct or buy new. Accumulated depreciation totaled $1,469.8 million and $1,450.1 million at March 31, 2015 and December 31, 2014, respectively.
	Consistent with authoritative guidance, we assess the carrying amount of long-lived assets with definite lives that are held-for-use and evaluate them for recoverability whenever events or changes in circumstances indicate that we may be unable to recover the carrying amount of the assets. During the first quarter of 2014, we permanently closed our Long Island tissue converting and distribution facility. As a result of this closure, we considered an outside third party's appraisal in assessing the recoverability of the facility's long-lived plant and equipment based on available market data for comparable assets sold through private party transactions. Based on this assessment, we determined the carrying amounts of certain long-lived plant and equipment related to the Long Island facility exceeded their fair value. As a result, we recorded a $3.0 million non-cash impairment charge to our accompanying Consolidated Statement of Operations for the three months ended March 31, 2014. There were no other such events or changes in circumstances that impacted our remaining long-lived assets.
STOCKHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY
	On December 15, 2014, we announced that our Board of Directors had approved a new stock repurchase program authorizing the repurchase of up to $100 million of our common stock. The repurchase program authorizes purchases of our common stock from time to time through open market purchases, negotiated transactions or other means, including accelerated stock repurchases and 10b5-1 trading plans in accordance with applicable securities laws and other restrictions. We have no obligation to repurchase stock under this program and may suspend or terminate the program at any time. During the first quarter of 2015, we repurchased 599,495 shares of our outstanding common stock at an average price of $61.97 per share. As of March 31, 2015, we had up to $62.9 million of authorization remaining pursuant to this stock repurchase program.
	On February 5, 2014, we announced that our Board of Directors had approved a stock repurchase program authorizing the repurchase of up to $100 million of our common stock. We completed that program during the third quarter of 2014. In total, we repurchased 1,574,748 shares of our outstanding common stock at an average price of $63.50 per share under that program.
DERIVATIVES	DERIVATIVES
	We had no activity during the three months ended March 31, 2015 and 2014 that required hedge or derivative accounting treatment. However, to help mitigate our exposure to market risk for changes in utility commodity pricing, we use firm price contracts to supply a portion of the natural gas requirements for our manufacturing facilities. As of March 31, 2015, these contracts covered approximately 53% of our expected average monthly natural gas requirements for the remainder of 2015. Historically, these contracts have qualified for treatment as “normal purchases or normal sales” under authoritative guidance and thus required no mark-to-market adjustment.
