Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
GENERAL | GENERAL Nature of Operations As used in this Report, the terms “Ciner Resources LP,” “the “Partnership,” “CINR,” “we,” “us,” or “our” may refer to Ciner Resources LP, formerly OCI Resources LP, a publicly traded Delaware limited partnership formed in April 2013 by Ciner Wyoming Holding Co. (“Ciner Holdings” or ), formerly OCI Wyoming Holding Co. Ciner Holdings, a wholly-owned subsidiary of Ciner Resources Corporation (“Ciner Corp”), formerly OCI Chemical Corporation, wholly-owned Ciner Resource Partners LLC (our “general partner” or “Ciner GP”), formerly OCI Resource Partners LLC. Ciner Corp is a direct wholly-owned subsidiary of Ciner Enterprises Inc. (“Ciner Enterprises”), which is directly wholly-owned by WE Soda Ltd. (“WE Soda”), which is directly wholly-owned by KEW Soda Ltd. (“KEW Soda”), which is directly wholly-owned by Akkan Enerji ve Madencilik Anonim Şirketi (“Akkan”), which in turn is directly wholly-owned by Turgay Ciner, the Chairman of the Ciner Group, a Turkish conglomerate of companies engaged in energy and mining (including soda ash mining), media and shipping markets. Ciner Wyoming LLC (“Ciner Wyoming”), formerly OCI Wyoming LLC, is in the business of mining trona ore to produce soda ash, and a majority-owned subsidiary of the Partnership. The Partnership’s operations consist solely of its investment in Ciner Wyoming. The Partnership owns a controlling interest comprised of 51.0% membership interest in Ciner Wyoming. All our soda ash processed is sold to various domestic and European customers, and to Ciner Ic ve Dis Ticaret Anonim Sirketi (“CIDT”) and American Natural Soda Ash Corporation (“ANSAC”) which are affiliates for export sales. All mining and processing activities take place in one facility located in the Green River Basin of Wyoming. NRP Trona LLC, a wholly owned subsidiary of Natural Resource Partners LP (“NRP”), currently owns a 49.0% membership interest in Ciner Wyoming. On February 22, 2018, Akkan transferred its direct 100% ownership in Ciner Enterprises to KEW Soda, a UK company, which transferred such ownership to WE Soda, a UK company. WE Soda is 100% owned by KEW Soda, and KEW Soda is wholly owned by Akkan. This reorganization is a part of Ciner Group’s strategy to combine the global soda ash business under a common structure in the UK. Completed Sale Transaction On October 23, 2015 , Ciner Enterprises acquired 100% of OCI Chemical Corporation in a stock purchase transaction from OCI Enterprises Inc. (“OCI Enterprises”) (the “Transaction”). OCI Chemical Corporation was subsequently renamed Ciner Resources Corporation. Ciner Corp owns indirectly the Partnership, through Ciner Holdings’, approximately 73% limited partner interest, and approximately 2% general partner interest and 100% of the related incentive distribution rights currently held by our general partner. As a result of the closing of the Transaction, OCI Enterprises no longer has any direct or indirect ownership interest in the Partnership or our general partner. In connection with the closing of the Transaction, Ciner Enterprises (as borrower), and Ciner Holdings and Ciner Corp (as guarantors), entered into a credit agreement (as amended and restated or otherwise modified, the “Ciner Enterprises Credit Agreement”), which expires on October 23, 2025 and is secured by certain assets, including the common units of the Partnership owned by Ciner Holdings. On November 5, 2015 , in connection with the closing of the Transaction, the Partnership changed its name from OCI Resources LP to Ciner Resources LP. |

Accounting Policies [Abstract] | |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Significant Accounting Policies The accompanying consolidated financial statements of the Partnership and its subsidiary have been prepared in conformity with U.S. generally accepted accounting principles and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All significant intercompany transactions, balances, revenue and expenses have been eliminated in consolidation and unless otherwise noted, the financial information for the Partnership is presented before non-controlling interest. Reclassifications To conform to the presentation as of December 31, 2017, we made a reclassification in the consolidated balance sheet as of December 31, 2016 to include $46.5 million of “Accounts receivable - ANSAC”, $9.0 million of “Accounts receivable - other affiliate” and $6.1 million of “Due from affiliates, net” within “Accounts receivable -affiliates”. This reclassification had no effect on “Total current assets” as of December 31, 2016. We also made a corresponding reclassification in the statements of cash flows for the years ended December 31, 2016 and 2015 to include changes within “Accounts receivable -affiliates” to include $5.7 million and $18.2 million of “Accounts receivable - ANSAC”, $9.0 million of “Accounts receivable - other affiliate” and $5.7 million and $7.7 million of “Due from affiliates, net” within “Accounts receivable -affiliates” among the changes in operating assets and liabilities. These reclassifications had no effect on net cash provided by operating activities for any period. Non-Controlling Interests In connection with the conversion of Ciner Wyoming from a Delaware limited partnership (“LP”) to a Delaware limited liability company (“LLC”), in June 2014, NRP’s general partner interest and limited partnership interest were converted into a single-class of membership interests in Ciner Wyoming, which currently consists of 49.0% membership interest in Ciner Wyoming. Prior to the conversion of Ciner Wyoming from a Delaware LP to a Delaware LLC, non-controlling interests in the consolidated financial statements of the Partnership consisted of 39.37% general partner interest and 9.63% limited partner interest in Ciner Wyoming owned by NRP. Use of Estimates The preparation of consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition For the year ended December 31, 2017 , we recognize revenue when the earnings process is complete, which is generally upon transfer of title. This transfer typically occurs upon shipment to the customer, which is normally free on board (“FOB”) terms or upon receipt by the customer. In all cases, we apply the following criteria in recognizing revenue: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the selling price is fixed, determinable or reasonably estimated sales price has been agreed with the customer; and (4) collectability is reasonably assured. Customer rebates and discounts are accounted for as sales deductions. We record amounts billed for shipping and handling fees as revenue. Costs incurred for shipping and handling are recorded as costs of products sold. Freight Costs The Partnership includes freight costs billed to customers for shipments administered by the Partnership in gross sales. The related freight costs along with cost of products sold are deducted from gross sales to determine gross profit. Cash and Cash Equivalents The Partnership considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of money market deposit accounts. Accounts Receivable Accounts receivable are carried at the original invoice amount less an estimate for doubtful receivables. We generally do not require collateral against outstanding accounts receivable.The allowance for doubtful accounts is based on specifically identified amounts that the Partnership believes to be uncollectible. An additional allowance is recorded based on certain percentages of aged receivables, which are determined based on management’s assessment of the general financial conditions affecting the Partnership’s customer base. We determined that no allowance for doubtful accounts was required against receivables from affiliates as of December 31, 2017 and 2016. If actual collection experience changes, revisions to the allowance may be required. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received. During the years ended 2017 , 2016 and 2015 , there were no significant accounts receivable bad debt expenses, write-offs or recoveries. Inventory Inventory is carried at the lower of cost or market. Cost is determined using the first-in, first-out method for raw material and finished goods inventory and the weighted average cost method for stores inventory. Costs include raw materials, direct labor and manufacturing overhead. Market is based on current replacement cost for raw materials and net realizable value for stores inventory and finished goods. • Raw material inventory includes material, chemicals and natural resources being used in the mining and refining process. • Finished goods inventory is the finished product soda ash. • Stores inventory includes parts, materials and operating supplies which are typically consumed in the production of soda ash and currently available for future use. Inventory expected to be consumed within the year is classified as current assets and remainder is classified as non-current assets. Property, Plant, and Equipment Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of depreciable assets, using the straight-line method. The estimated useful lives applied to depreciable assets are as follows: Useful Lives Land improvements 10 years Depletable land 15-60 years Buildings and building improvements 10-30 years Internal-use computer software 3-5 years Machinery and equipment 5-20 years Furniture and fixtures 10 years The Partnership’s policy is to evaluate property, plant, and equipment for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. An indicator of potential impairment would include situations when the estimated future undiscounted cash flows are less than the carrying value. The amount of any impairment then recognized would be calculated as the difference between estimated fair value and the carrying value of the asset. Derivative Instruments and Hedging Activities The Partnership may enter into derivative contracts from time to time to manage exposure to the risk of exchange rate changes on its foreign currency transactions, the risk of changes in natural gas prices, and the risk of the variability in interest rates on borrowings. Gains and losses on derivative contracts qualifying for hedge accounting are reported as a component of the underlying transactions. The Partnership follows hedge accounting for its hedging activities. All derivative instruments are recorded on the balance sheet at their fair values. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Partnership designates its derivatives based upon criteria established for hedge accounting under generally accepted accounting principles. For a derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified into earnings when the hedged exposure affects earnings. Any significant ineffective portion of the gain or loss is reported in earnings immediately. For derivatives not designated as hedges, the gain or loss is reported in earnings in the period of change. The natural gas physical forward contracts are accounted for under the normal purchases and normal sales scope exception. Income Tax We are organized as a pass-through entity for federal income tax purposes and therefore are not subject to federal or certain state income taxes. As a result, our partners are responsible for federal income taxes based on their respective share of taxable income. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement. Technical Termination of the Partnership for U.S. Federal Income Tax Purposes In 2015, the Partnership experienced a technical termination as a result of the Transaction, which also resulted in a technical termination of Ciner Wyoming, for U.S. federal income tax purposes. The technical termination did not affect our consolidated financial statements nor did it affect our classification or Ciner Wyoming’s classification as a partnership or otherwise affect the nature or extent of our “qualifying income” for U.S. federal income tax purposes. Our 2015 taxable year for all then unitholders ended on October 23, 2015 and resulted in a deferral of depreciation deductions that were otherwise allowable in computing the taxable income of our unitholders. This deferral of depreciation deductions resulted in an increased taxable income (or reduced taxable loss) to certain of our unitholders in 2015. We did not view this deferral of depreciation deductions to have had a material adverse impact on our public common unitholders. As of December, 31, 2017 , the Partnership has not participated in any transactions or experienced a sale or exchange of 50% or more of the total interest in our capital and profits interests within a twelve-month period. Reclamation Costs The Partnership is obligated to return the land beneath its refinery and tailings ponds to its natural condition upon completion of operations and is required to return the land beneath its rail yard to its natural condition upon termination of the various lease agreements. The Partnership accounts for its land reclamation liability as an asset retirement obligation, which requires that obligations associated with the retirement of a tangible long-lived asset be recorded as a liability when those obligations are incurred, with the amount of the liability initially measured at fair value. Upon initially recognizing a liability for an asset retirement obligation, an entity must capitalize the cost by recognizing an increase in the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the estimated useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The estimated original liability calculated in 1996 for the refinery and tailing ponds was calculated based on the estimated useful life of the mine, which was 80 years , and on external and internal estimates as to the cost to restore the land in the future and state regulatory requirements. During 2017 , 2016 and 2015 , the remaining life was 66 , 67 and 68 years, respectively. In 2018 , the mining reserve will be amortized over a remaining life of 60 years. The decline in estimated mining reserves estimated remaining life is based on the results of a recent independent mine reserve analysis conducted as of December 31, 2017. The independent mine reserve analysis is routine and performed approximately every three years.The liability was discounted using a weighted average credit-adjusted risk-free rates of approximately 6% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold. During 2011 , the Partnership constructed a rail yard to facilitate loading and switching of rail cars. The Partnership is required to restore the land on which the rail yard is constructed to its natural conditions. The original estimated liability for restoring the rail yard to its natural condition was calculated based on the land lease life of 30 years and on external and internal estimates as to the cost to restore the land in the future. The liability is discounted using a credit-adjusted risk-free rate of 4.25% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold. Fair Value of Financial Instruments Fair value is determined using a valuation hierarchy, generally by reference to an active trading market, quoted market prices or model-derived valuations for the same or similar financial instruments. See Note 17, “Fair Value Measurements,” for more information. Equity-Based Compensation We recognize compensation expense related to equity-based awards, with service conditions, granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. Equity-based awards with market conditions are fair valued using a Monte Carlo Simulation model. See Note 12, “Equity-Based Compensation - TR Performance Unit Awards,” for additional information. Subsequent Events We have evaluated subsequent events through the filing of this Annual Report on Form 10-K. See Note 18, “Subsequent Events” for additional information. Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. The Partnership should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Partnership has completed its evaluation of the provisions of this ASU and does not expect our adoption of ASU 2014-09 to materially change the amount or timing of revenues recognized by us, nor expect it to materially affect our financial position. The majority of our revenues generated are recognized upon delivery and transfer of title to the product to our customers. The time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the product leaves our facility, thereby rendering our performance obligation fulfilled. The FASB issued various amendments to ASU 2014-09, one of which includes allowing entities to elect to account for shipping and handling activities performed after the control of a good has been transferred to the customer as a fulfillment cost versus an obligation of a promised service. The Partnership has made an accounting policy election upon adoption to account for shipping and handling activities as fulfillment costs, which is not expected to have a material impact on our financial statements. The Partnership adopted this ASU effective January 1, 2018, as permitted by the ASU, using the modified retrospective method. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining largely unchanged from current guidance. The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update is effective for interim and annual periods beginning after December 15, 2018 and must be adopted using a modified retrospective transition. The ASU No. 2016-02 provides for certain practical expedients and early adoption is permitted. The Partnership is evaluating the potential impact the adoption of ASU No. 2016-02 will have on its consolidated financial statements. In August 2017, FASB issued ASU 2017-12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities. This ASU aims to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, this ASU make certain targeted improvements to simplify the application of the existing hedge accounting guidance. This ASU is effective for us beginning in the first quarter of 2019, with early application permitted. The Partnership is evaluating the effect the standard will have on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09–Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The updated guidance is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. We do not believe the updated requirements will materially impact the Partnership’s consolidated financial statements. |

Earnings Per Share [Abstract] | |
NET INCOME PER UNIT AND CASH DISTRIBUTION | NET INCOME PER UNIT AND CASH DISTRIBUTION Allocation of Net Income Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income attributable to Ciner Corp, after deducting the general partner’s interest and any incentive distributions, by the weighted average number of outstanding common and subordinated units. Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit. In addition to the common units, we have also identified the general partner interest and incentive distribution rights (“IDRs”) as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Anti-dilutive units outstanding were immaterial for all periods presented. The net income attributable to common and subordinated unitholders and the weighted average units for calculating basic and diluted net income per common and subordinated units were as follows: Year Ended December 31, (In millions, except per unit data) 2017 2016 2015 Net income attributable to Ciner Resources LP $ 41.6 $ 41.4 $ 51.5 Less: General partner’s interest in net income 0.8 0.8 1.0 Limited partners’ interest in net income $ 40.8 $ 40.6 $ 50.5 Weighted average limited partner units outstanding: Common - Public and Ciner Holdings (basic) 19.6 12.3 9.8 Subordinated - Ciner Holdings (basic) — 7.3 9.8 Total weighted average limited partner units outstanding (basic) 19.6 19.6 19.6 Common - Public and Ciner Holdings (diluted) 19.7 12.3 9.8 Subordinated - Ciner Holdings (diluted) — 7.3 9.8 Total weighted average limited partner units outstanding (diluted) 19.7 19.6 19.6 Net income per limited partner unit: Common - Public and Ciner Holdings (basic) $ 2.08 $ 2.06 $ 2.58 Subordinated - Ciner Holdings (basic) $ — $ 2.11 $ 2.58 Net income per limited partner units (basic) $ 2.08 $ 2.08 $ 2.58 Common - Public and Ciner Holdings (diluted) $ 2.07 $ 2.06 $ 2.58 Subordinated - Ciner Holdings (diluted) $ — $ 2.11 $ 2.58 Net income per limited partner units (diluted) $ 2.07 $ 2.08 $ 2.58 The calculation of limited partners’ interest in net income is as follows: Year Ended December 31, (In millions, except per unit data) 2017 2016 2015 Net income attributable to common unitholders: Distributions (1) $ 44.5 $ 27.9 $ 21.5 (Distributions in excess of net income)/undistributed earnings (3.7 ) (2.7 ) 3.8 Common unitholders’ interest in net income $ 40.8 $ 25.2 $ 25.3 Net income attributable to subordinated unitholders: Distributions (1) $ — $ 16.6 $ 21.4 (Distributions in excess of net income)/undistributed earnings — (1.2 ) 3.8 Subordinated unitholders’ interest in net income $ — $ 15.4 $ 25.2 (1) Distributions declared per unit for the year 2.268 2.265 2.191 Conversion of subordinated units Upon payment of the quarterly distribution for the third quarter of 2016, the conditions for conversion of the Partnership’s subordinated units were satisfied. Accordingly, effective on November 14, 2016, the Partnership’s 9,775,500 subordinated units converted into common units on a one -for-one basis. For purposes of calculating net income per common and subordinated units, the conversion of the subordinated units were deemed to have occurred on October 1, 2016. Quarterly Distribution On February 1, 2018 , the Partnership declared its fourth quarter 2017 quarterly distribution. The quarterly cash distribution of $0.5670 per unit was paid on February 27, 2018 to unitholders of record on February 12, 2018 . Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders at our current quarterly distribution level, at the minimum quarterly distribution level or at any other rate, and we have no legal obligation to do so. However, our partnership agreement does contain provisions intended to motivate our general partner to make steady, increasing and sustainable distributions over time. General Partner Interest and Incentive Distribution Rights Our partnership agreement provides that our general partner initially will be entitled to 2.0% of all distributions that we make prior to our liquidation. Our general partner has the right, but not the obligation, to contribute up to a proportionate amount of capital to us in order to maintain its 2.0% general partner interest if we issue additional units. Our general partner’s approximate 2.0% interest, and the percentage of our cash distributions to which our general partner is entitled from such approximate 2.0% interest, will be proportionately reduced if we issue additional units in the future (other than the issuance of common units upon a reset of the IDRs), and our general partner does not contribute a proportionate amount of capital to us in order to maintain its approximate 2.0% general partner interest. Our partnership agreement does not require that our general partner fund its capital contribution with cash. It may, instead, fund its capital contribution by contributing to us common units or other property. IDRs represent the right to receive increasing percentages ( 13.0% , 23.0% and 48.0% ) of quarterly distributions from operating surplus after we have achieved the minimum quarterly distribution and the target distribution levels. Our general partner currently holds the IDRs, but may transfer these rights separately from its general partner interest, subject to certain restrictions in our partnership agreement. Percentage Allocations of Distributions from Operating Surplus The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading "Marginal Percentage Interest in Distributions" are the percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column "Total Quarterly Distribution per Unit Target Amount." The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution also apply to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner (1) include a 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its incentive distribution rights and (4) assume there are no arrearages on common units. Marginal Percentage Interest in Distributions Total Quarterly Distribution per Unit Target Amount Unitholders General Partner Minimum Quarterly Distribution $0.5000 98.0 % 2.0 % First Target Distribution above $0.5000 up to $0.5750 98.0 % 2.0 % Second Target Distribution above $0.5750 up to $0.6250 85.0 % 15.0 % Third Target Distribution above $0.6250 up to $0.7500 75.0 % 25.0 % Thereafter above $0.7500 50.0 % 50.0 % |

The revenue bond requires the Partnership to maintain standby letters of credit totaling $11.6 million and $20.3 million at December 31, 2017 and December 31, 2016 , respectively. The letter of credit requires compliance with certain covenants, including minimum net worth, maximum debt to net worth, and interest coverage ratio. As of December 31, 2017 and December 31, 2016 , Ciner Wyoming was in compliance with these debt covenants. Ciner Wyoming Credit Facility On August 1, 2017, Ciner Wyoming entered into a Credit Agreement (“Ciner Wyoming Credit Facility”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, National Association, as administrative agent, swing line lender and a Letter of Credit (“ L/C”) issuer. The Ciner Wyoming Credit Facility replaces the former Credit Facility, dated as of July 18, 2013, by and among Ciner Wyoming, the lenders party thereto and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer, as amended (the “Former Ciner Wyoming Credit Facility”), which was terminated on August 1, 2017 upon entry into the Ciner Wyoming Credit Facility. This arrangement was accounted for as a modification of debt in accordance with Accounting Standards Codification (“ASC”) 470-50. The Ciner Wyoming Credit Facility is a $225.0 million senior unsecured revolving credit facility with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The Ciner Wyoming Credit Facility provides for revolving loans to fund working capital requirements, capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Ciner Wyoming Credit Facility has an accordion feature that allows Ciner Wyoming to increase the available revolving borrowings under the facility by up to an additional $75.0 million , subject to Ciner Wyoming receiving increased commitments from existing lenders or new commitments from new lenders and the satisfaction of certain other conditions. In addition, the Ciner Wyoming Credit Facility includes a sublimit up to $20.0 million for same-day swing line advances and a sublimit up to $40.0 million for letters of credit. Ciner Wyoming’s obligations under the Ciner Wyoming Credit Facility are unsecured. The Ciner Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain exceptions) Ciner Wyoming’s ability to: • make distributions on or redeem or repurchase units; • incur or guarantee additional debt; • make certain investments and acquisitions; • incur certain liens or permit them to exist; • enter into certain types of transactions with affiliates of Ciner Wyoming; • merge or consolidate with another company; and • transfer, sell or otherwise dispose of assets. The Ciner Wyoming Credit Facility also requires quarterly maintenance of a consolidated leverage ratio (as defined in the Ciner Wyoming Credit Facility) of not more than 3.00 to 1.00 and a consolidated interest coverage ratio (as defined in the Ciner Wyoming Credit Facility) of not less than 3.00 to 1.00. The Ciner Wyoming Credit Facility contains events of default customary for transactions of this nature, including (i) failure to make payments required under the Ciner Wyoming Credit Facility, (ii) events of default resulting from failure to comply with covenants and financial ratios in the Ciner Wyoming Credit Facility, (iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against Ciner Wyoming and (v) the occurrence of a default under any other material indebtedness Ciner Wyoming may have. Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the Ciner Wyoming Credit Facility, the administrative agent at the request of shall, or with the consent of the Required Lenders (as defined in the Ciner Wyoming Credit Facility) may terminate all outstanding commitments under the Ciner Wyoming Credit Facility and may declare any outstanding principal of the Ciner Wyoming Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable. Under the Ciner Wyoming Credit Facility, a change of control is triggered if Ciner Resources Corporation and its wholly-owned subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority of the board of directors (or similar governing body) of the General Partner (or any entity that performs the functions of the Partnership’s general partner). In addition, a change of control would be triggered if the Partnership ceases to own at least 50.1% of the economic interests in Ciner Wyoming or cease to have the ability to elect a majority of the members of Ciner Wyoming’s board of managers. Loans under the Ciner Wyoming Credit Facility bear interest at Ciner Wyoming’s option at either: • a Base Rate, which equals the highest of (i) the federal funds rate in effect on such day plus 0.50% , (ii) the administrative agent’s prime rate in effect on such day or (iii) one-month LIBOR plus 1.0% , in each case, plus an applicable margin; or • Eurodollar Rate plus an applicable margin. The unused portion of the Ciner Wyoming Credit Facility is subject to an unused line fee ranging from 0.225% to 0.300% per annum based on Ciner Wyoming’s then current consolidated leverage ratio. At December 31, 2017, Ciner Wyoming was in compliance with all financial covenants of the Ciner Wyoming Credit Facility. Revolving Credit Facility On August 1, 2017, the Partnership entered into a Credit Agreement (the “Revolving Credit Facility”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, National Association, as administrative agent, swing line lender and an L/C issuer. The Revolving Credit Facility replaces the former Credit Facility, dated as of July 18, 2013, by and among the Partnership, the lenders party thereto and Bank of America, N.A., as administrative agent, swing line lender and L/C issuer, as amended (the “Former Revolving Credit Facility”), which was terminated on August 1, 2017 upon entry into the Ciner Resources Credit Facility. The Revolving Credit Facility is a $10.0 million senior secured revolving credit facility with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The Revolving Credit Facility provides for revolving loans to be available to fund distributions on the Partnership’s units and working capital requirements and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Revolving Credit Facility includes a sublimit up to $5.0 million for same-day swing line advances and a sublimit up to $5.0 million for letters of credit. The Partnership’s obligations under the Revolving Credit Facility are guaranteed by each of the Partnership’s material domestic subsidiaries other than Ciner Wyoming LLC (“Ciner Wyoming”). In addition, the Partnership’s obligations under the Revolving Credit Facility are secured by a pledge of substantially all of the Partnership’s assets (subject to certain exceptions), including the membership interests held in Ciner Wyoming by the Partnership.

Under the Revolving Credit Facility, a change of control is triggered if Ciner Resources Corporation and its wholly-owned subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority of the board of directors (or similar governing body) of, Ciner Wyoming Holding Co. or Ciner Resource Partners LLC (or any entity that performs the functions of the Partnership’s general partner). In addition, a change of control would be triggered if the Partnership ceases to own at least 50.1% of the economic interests in Ciner Wyoming or ceases to have the ability to elect a majority of the members of Ciner Wyoming’s board of managers. Loans under the Revolving Credit Facility bear interest at our option at either: • a Base Rate, which equals the highest of (i) the federal funds rate in effect on such day plus 0.50 %, (ii) the administrative agent’s prime rate in effect on such day or (iii) one-month LIBOR plus 1.0% , in each case, plus an applicable margin; or • Eurodollar Rate plus an applicable margin. The unused portion of the Revolving Credit Facility is subject to an unused line fee ranging from 0.225% to 0.300% based on our then current consolidated leverage ratio.

Retirement Benefits [Abstract] | |
EMPLOYEE COMPENSATION | EMPLOYEE COMPENSATION The Partnership participates in various benefit plans offered and administered by Ciner Corp (administered by OCI Enterprises prior to the Transaction) and is allocated its portions of the annual costs related thereto. The specific plans are as follows: Retirement Plans - Benefits provided under the pension plan for salaried employees and pension plan for hourly employees (collectively, the “Retirement Plans”) are based upon years of service and average compensation for the highest 60 consecutive months of the employee’s last 120 months of service, as defined. Each plan covers substantially all full-time employees hired before May 1, 2001. The retirement plans had an accumulated benefit obligation of $57.4 million and $61.5 million at December 31, 2017 and 2016 , respectively. The funding policy is to contribute an amount within the range of the minimum required and the maximum tax-deductible contribution. The Partnership’s allocated portion of the Retirement Plan’s net periodic pension costs as of December 31, 2017 , 2016 and 2015 were $1.4 million , $2.0 million and $7.7 million . The decrease in pension costs during 2017 was primarily driven by improved discount rates while the decrease in 2016 was driven by lower overall pension cost at the Ciner Corp level as a result of the retirement plans being fair valued in connection with Ciner Enterprises’ acquisition of Ciner Corp. Savings Plan - The 401(k) retirement plan (the “401(k) Plan”) covers all eligible hourly and salaried employees. Eligibility is limited to all domestic residents and any foreign expatriates who are in the United States indefinitely. The plan permits employees to contribute specified percentages of their compensation, while the Partnership makes contributions based upon specified percentages of employee contributions. Participants hired on or subsequent to May 1, 2001, will receive an additional contribution from the Partnership based on a percentage of the participant’s base pay. Contributions made to the 401(k) Plan for as of December 31, 2017 , 2016 and 2015 were $3.7 million , $1.6 million and $2.6 million , respectively. The increase during 2017 was primarily due to the incremental contributions that were not made in the 2016 comparative period due the the acquisition of the Partnership’s parent company and the accelerated payouts in 2015. Postretirement Benefits - Most of the Partnership’s employees are eligible for postretirement benefits other than pensions if they reach retirement age while still employed. The postretirement benefits are accounted for on an accrual basis over an employee’s period of service. The postretirement plan, excluding pensions, are not funded, and Ciner Corp has the right to modify or terminate the plan. The post-retirement benefits had a benefits obligation of $11.5 million and $20.6 million at December 31, 2017 and December 31, 2016 , respectively. The decrease in the obligation as of December 31, 2017 as compared to December 31, 2016 is due to the Partnership amending its postretirement benefit plan to increase eligibility requirements at which participants may begin receiving benefits, implemented a subsidy rather than a premium for the benefit plan, and eliminating plan eligibility for individuals hired after December 31, 2016 . The Partnership’s allocated portion of postretirement (benefit) costs as of December 31, 2017 , 2016 and 2015 were $(2.8) million , $1.4 million and $0.5 million , respectively. The postretirement benefit for the Partnership in 2017 is due to the aforementioned changes made to the postretirement benefit plans during 2017. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
EQUITY - BASED COMPENSATION | EQUITY - BASED COMPENSATION In July 2013, our general partner established the Ciner Resource Partners LLC 2013 Long-Term Incentive Plan (the “Plan” or “LTIP”). The Plan is intended to provide incentives that will attract and retain valued employees, officers, consultants and non-employee directors by offering them a greater stake in our success and a closer identity with us, and to encourage ownership of our common units by such individuals. The Plan provides for awards in the form of common units, phantom units, distribution equivalent rights (“DERs”), cash awards and other unit-based awards. All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the Plan. As of December 31, 2017 , subject to further adjustment as provided in the Plan, a total of 0.7 million common units were available for awards under the Plan. Any common units tendered by a participant in payment of the tax liability with respect to an award, including common units withheld from any such award, will not be available for future awards under the Plan. Common units awarded under the Plan may be reserved or made available from our authorized and unissued common units or from common units reacquired (through open market transactions or otherwise). Any common units issued under the Plan through the assumption or substitution of outstanding grants from an acquired company will not reduce the number of common units available for awards under the Plan. If any common units subject to an award under the Plan are forfeited, any common units counted against the number of common units available for issuance pursuant to the Plan with respect to such award will again be available for awards under the Plan. Non-employee Director Awards During the twelve months ended December 31, 2017 , a total of 7,887 common units were granted and fully vested to non-employee directors, and 7,251 were grants during the twelve months ended December 31, 2016 . The grant date average fair value per unit of these awards was $28.53 and $26.24 for the twelve months ended December 31, 2017 and 2016 , respectively. The total fair value of these awards were approximately $0.2 million during the twelve months ended December 31, 2017 and 2016 , respectively. Time Restricted Unit Awards We grant restricted unit awards in the form of common units to certain employees which vest over a specified period of time, usually between one to three years, with vesting based on continued employment as of each applicable vesting date. Award recipients are entitled to distributions subject to the same restrictions as the underlying common unit. The awards are classified as equity awards, and are accounted for at fair value at grant date. The following table presents a summary of activity on the Time Restricted Unit Awards for the years ended December 31: 2017 2016 (Units in whole numbers) Number of Units Grant-Date Average Fair Value per Unit (1) Number of Units Grant-Date Average Fair Value per Unit (1) Unvested at the beginning of year 39,170 $ 22.50 — $ — Granted (1) 80,370 28.41 39,170 22.50 Vested (13,055 ) 22.50 — — Forfeited (11,694 ) 24.90 — — Unvested at the end of the year 94,791 $ 27.22 39,170 $ 22.50 (1) Determined by dividing the aggregate grate date fair value of awards by the number of awards issued. No estimated forfeiture rate was applied to the awards as of December 31, 2017 as all awards granted are expected to vest. Total Return Performance Unit Awards We grant TR Performance Unit Awards to certain employees. The TR Performance Unit Awards represent the right to receive a number of common units at a future date based on the achievement of market-based performance requirements in accordance with the TR Unit Performance Award agreement, and also include Distribution Equivalent Rights (“DERs”). DERs are the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued upon vesting. The TR Performance Unit Awards vest at the end of the performance period, usually between two to three years from the date of the grant. Performance is measured on the achievement of a specified level of total return, or TR, relative to the TR of a peer group comprised of other limited partnerships. The potential payout ranges from 0 - 200% of the grant target quantity and is adjusted based on our TR performance relative to the peer group. For purposes of the table below the number of units are included at target quantity. We utilized a Monte Carlo simulation model to estimate the grant date fair value of TR Performance Unit Awards granted to employees. These type of awards, with market conditions, require the input of highly subjective assumptions, including expected volatility and expected distribution yield. Historical and implied volatilities were used in estimating the fair value of these awards. The following table presents a summary of activity on the TR Performance Unit Awards for the years ended December 31: 2017 2016 (Units in whole numbers) Number of Units Grant-Date Average Fair Value per Unit (1) Number of Units Grant-Date Average Fair Value per Unit (1) Unvested at the beginning of year 5,787 $ 43.93 — $ — Granted 22,849 42.73 5,787 43.93 Forfeited (2,459 ) 43.47 — — Unvested at the end of the year 26,177 $ 42.93 5,787 $ 43.93 (1) Determined by dividing the aggregate grant date fair value of awards by the number of awards issued.

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Lease Commitments The Partnership leases mineral rights from the U.S. Bureau of Land Management, the state of Wyoming, Rock Springs Royalty Corp, an affiliate of Anadarko Petroleum, and other private parties. All of these leases provide for royalties based upon production volume. The remaining leases provide for minimum lease payments as detailed in the table below. The Partnership has a perpetual right of first refusal with respect to these leases and intends to continue renewing the leases as has been its practice. The Partnership entered into a 10 year rail yard switching and maintenance agreement with a third party, Watco Companies, LLC (“Watco”), on December 1, 2011. Under the agreement, Watco provides rail-switching services at the Partnership’s rail yard. The Partnership’s rail yard is constructed on land leased by Watco from Rock Springs Grazing Association and on land by which Watco holds an easement from Anadarko Land Corp; the Rock Springs Grazing Association land lease is renewable every 5 years for a total period of 30 years , while the Anadarko Land Corp. easement lease is perpetual. The Partnership has an option agreement with Watco to assign these leases to the Partnership at any time during the land lease term. An annual rental of $15 thousand is paid under the easement and an annual rental of $60 thousand is paid under the lease. The Partnership entered into two track lease agreements, collectively, not to exceed 10 years with Union Pacific for certain rail tracks used in connection with the rail yard. As of December 31, 2017 , the total minimum contractual rental commitments under the Partnership’s various operating leases, including renewal periods, are as follows: (In millions) Leased Land Track Leases Total Minimum Lease Payments 2018 0.10 0.10 0.20 2019 0.10 0.10 0.20 2020 0.10 0.10 0.20 2021 0.10 — 0.10 2022 0.10 — 0.10 Thereafter 1.40 — 1.40 Total $ 1.9 $ 0.3 $ 2.2 Ciner Corp, on behalf of the Partnership, typically enters into operating lease contracts with various lessors for railcars to transport product to customer locations and warehouses. Rail car leases under these contractual commitments range for periods from 1 to 10 years. Ciner Corp's obligation related to these rail car leases are $12.1 million in 2018 , $11.1 million in 2019 , $8.5 million in 2020 , $5.9 million in 2021 , $3.8 million in 2022 and $6.2 million in 2023 and thereafter. Total lease expense was approximately $14.6 million , $14.5 million and $12.4 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Purchase Commitments We have natural gas supply contracts to mitigate volatility in the price of natural gas. As of December 31, 2017 , these contracts totaled approximately $29.6 million for the purchase of a portion of our natural gas requirements over approximately the next five years. The supply purchase agreements have specific commitments of $14.3 million in 2018 , $8.4 million in 2019 and $6.9 million in 2020 . We have a separate contract that expires in 2021, for transportation of natural gas with an average annual cost of approximately $3.8 million per year. Legal Proceedings From time to time we are party to various claims and legal proceedings related to our business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any of the legal proceedings we are involved in to have a material effect on our business, financial condition and results of operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome of existing claims and legal proceedings and whether any damages resulting from them will be covered by insurance. Off-Balance Sheet Arrangements We have a self-bond agreement with the Wyoming Department of Environmental Quality under which we commit to pay directly for reclamation costs at our Green River, Wyoming plant site. The amount of the bond was $32.9 million as of December 31, 2017 and $38.2 million as of December 31, 2016 , which is the amount we would need to pay the State of Wyoming for reclamation costs if we cease mining operations currently. The amount of this self-bond is subject to change upon periodic re-evaluation by the Land Quality Division. |

Related Party Transactions [Abstract] | |
AGREEMENTS AND TRANSACTIONS WITH AFFILIATES | AGREEMENTS AND TRANSACTIONS WITH AFFILIATES Ciner Corp is the exclusive sales agent for the Partnership and through its membership in ANSAC, Ciner Corp is responsible for promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. ANSAC operates on a cooperative service-at-cost basis to its members such that typically any annual profit or loss is passed through to the members. In the event an ANSAC member exits or the ANSAC cooperative is dissolved, the exiting members are obligated for their respective portion of the residual net assets or deficit of the cooperative. All actual sales and marketing costs incurred by Ciner Corp are charged directly to the Partnership. Selling, general and administrative expenses also include amounts charged to the Partnership by its affiliates principally consisting of salaries, benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Partnership. Prior to the closing of the Transaction on October 23, 2015, under the Omnibus Agreement the Partnership reimbursed OCI Enterprises and its affiliates for the expenses incurred by them in providing services to the Partnership, and we also reimbursed OCI Enterprises for certain direct operating expenses they paid on our behalf. Subsequent to the closing of the Transaction, on October 23, 2015 the Partnership entered into a Services Agreement (the “Services Agreement”), among the Partnership, our general partner and Ciner Corp. Pursuant to the Services Agreement, Ciner Corp has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Ciner Corp an annual management fee and reimburse Ciner Corp for certain third-party costs incurred in connection with providing such services. In addition, under the joint venture agreement governing Ciner Wyoming, Ciner Wyoming reimburses us for employees who operate our assets and for support provided to Ciner Wyoming. These transactions do not necessarily represent arm's length transactions and may not represent all costs if the Company operated on a standalone basis. In November 2016, Ciner Corp, on behalf of Ciner Wyoming, entered into a soda ash sales agreement with CIDT, an affiliate of Ciner Group, that sells soda ash to markets not served by ANSAC. The terms of our sales agreement with CIDT are generally similar to our agreements with other international customers. The receivables associated with these sales are recorded in accounts receivable - affiliates line item on the balance sheet and interest earned is recorded in the interest income line item in the Statement of Operations and Comprehensive Income. CIDT is ultimately owned and controlled by the Ciner Group. As a result of the closing of the Transaction discussed in Note 2 - “Summary of Significant Accounting Policies,” Ciner Enterprises owns indirectly and controls the Partnership, therefore, OCI Enterprises and subsidiaries, including OCI Alabama LLC, are no longer related parties of the Partnership as of the Transaction date. The following table includes transactions with OCI Enterprises and subsidiaries prior to the Transaction date. The total costs charged to the Partnership by affiliates were as follows: Years Ended December 31, (In millions) 2017 2016 2015 OCI Enterprises $ — $ — $ 6.1 Ciner Corp 14.5 14.9 5.8 ANSAC (1) 2.4 3.8 3.8 Total selling, general and administrative expenses - Affiliates $ 16.9 $ 18.7 $ 15.7 (1) ANSAC allocates its expenses to its members using a pro rata calculation based on sales. Cost of products sold includes logistics services charged by ANSAC. For the years ended December 31, 2017 , 2016 and 2015 these costs were $19.8 million , $3.3 million and $8.2 million , respectively. The increase in freight costs charged by ANSAC was largely due to an increase in non-ANSAC international sales, primarily sales to CIDT, during the year ended December 31, 2017 compared to 2016 . When we elect to use ANSAC to provide freight services for our other non-ANSAC international sales, ANSAC separately and directly charges the Partnership for such services. Net sales to affiliates were as follows: Years Ended December 31, (In millions) 2017 2016 2015 ANSAC $ 222.2 $ 262.2 $ 261.0 OCI Alabama LLC — — 4.3 CIDT 82.3 9.0 — Total $ 304.5 $ 271.2 $ 265.3 The Partnership had accounts receivable from affiliates and due to affiliates as follows: As of December 31, (In millions) 2017 2016 2017 2016 Accounts receivable from affiliates Due to affiliates ANSAC 57.7 46.5 $ 1.3 $ 2.5 CIDT 32.9 9.0 — — Ciner Resources Corporation 7.7 3.9 1.7 1.7 Ciner Europe — 2.2 — — Total $ 98.3 $ 61.6 $ 3.0 $ 4.2 |

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS The Partnership measures certain financial and non-financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. Fair value disclosures are reflected in a three-level hierarchy, maximizing the use of observable inputs and minimizing the use of unobservable inputs. A three-level valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows: Level 1-inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. Level 2-inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability. Level 3-inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, derivative financial instruments and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate their fair value because of the nature of such instruments. Our long-term debt and derivative financial instruments are measured at their fair values with Level 2 inputs based on quoted market values for similar but not identical financial instruments. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Derivative Financial Instruments We have entered into interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible increases in interest rates. These contracts are for periods consistent with the exposure being hedged and will mature on July 18, 2018, the maturity date of the long-term debt under the Ciner Wyoming credit facility. These contracts had an aggregate notional value of $70.0 million at December 31, 2017 and $72.0 million at December 31, 2016 , respectively. We enter into natural gas forward contracts, designated as cash flow hedges, to mitigate volatility in the price of natural gas related to a portion of the natural gas we consume. These contracts generally have various maturities through 2022 . These contracts had an aggregate notional value of $37.0 million and $31.0 million at December 31, 2017 and December 31, 2016 , respectively. The following table presents the fair value of derivative assets and liability derivatives and the respective locations on our unaudited condensed consolidated balance sheets as of December 31, 2017 and December 31, 2016 : Assets Liabilities 2017 2016 2017 2016 (In millions) Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as hedges: Interest rate swap contracts - current $ — $ — Accrued Expenses $ — Accrued Expenses $ 0.4 Natural gas forward contracts - current Other Current Assets — 0.6 Accrued Expenses 1.9 Accrued Expenses — Natural gas forward contracts - non-current — — Other non-current liabilities 5.3 Other non-current liabilities 3.4 Foreign exchange forward contracts $ — $ — $ — $ — Total derivatives designated as hedging instruments $ — $ 0.6 $ 7.2 $ 3.8 Financial Assets and Liabilities not Measured at Fair Value The carrying value of our long-term debt materially reflects the fair value of our long-term debt as rates are variable and its key terms are similar to indebtedness with similar amounts, durations and credit risks.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies) | 12 Months Ended |
Dec. 31, 2017 | |
Accounting Policies [Abstract] | |
Basis of Presentation and Significant Accounting Policies | Basis of Presentation and Significant Accounting Policies The accompanying consolidated financial statements of the Partnership and its subsidiary have been prepared in conformity with U.S. generally accepted accounting principles and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All significant intercompany transactions, balances, revenue and expenses have been eliminated in consolidation and unless otherwise noted, the financial information for the Partnership is presented before non-controlling interest. |
Non-controlling interests | Non-Controlling Interests In connection with the conversion of Ciner Wyoming from a Delaware limited partnership (“LP”) to a Delaware limited liability company (“LLC”), in June 2014, NRP’s general partner interest and limited partnership interest were converted into a single-class of membership interests in Ciner Wyoming, which currently consists of 49.0% membership interest in Ciner Wyoming. Prior to the conversion of Ciner Wyoming from a Delaware LP to a Delaware LLC, non-controlling interests in the consolidated financial statements of the Partnership consisted of 39.37% general partner interest and 9.63% limited partner interest in Ciner Wyoming owned by NRP. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements, in accordance with accounting principles generally accepted in the United States of America, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
Revenue Recognition | Revenue Recognition For the year ended December 31, 2017 , we recognize revenue when the earnings process is complete, which is generally upon transfer of title. This transfer typically occurs upon shipment to the customer, which is normally free on board (“FOB”) terms or upon receipt by the customer. In all cases, we apply the following criteria in recognizing revenue: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the selling price is fixed, determinable or reasonably estimated sales price has been agreed with the customer; and (4) collectability is reasonably assured. Customer rebates and discounts are accounted for as sales deductions. We record amounts billed for shipping and handling fees as revenue. Costs incurred for shipping and handling are recorded as costs of products sold. |
Freight Costs | Freight Costs The Partnership includes freight costs billed to customers for shipments administered by the Partnership in gross sales. The related freight costs along with cost of products sold are deducted from gross sales to determine gross profit. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Partnership considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents consist primarily of money market deposit accounts. |
Accounts Receivable | Accounts Receivable Accounts receivable are carried at the original invoice amount less an estimate for doubtful receivables. We generally do not require collateral against outstanding accounts receivable.The allowance for doubtful accounts is based on specifically identified amounts that the Partnership believes to be uncollectible. An additional allowance is recorded based on certain percentages of aged receivables, which are determined based on management’s assessment of the general financial conditions affecting the Partnership’s customer base. We determined that no allowance for doubtful accounts was required against receivables from affiliates as of December 31, 2017 and 2016. If actual collection experience changes, revisions to the allowance may be required. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received. |
Inventory | Inventory Inventory is carried at the lower of cost or market. Cost is determined using the first-in, first-out method for raw material and finished goods inventory and the weighted average cost method for stores inventory. Costs include raw materials, direct labor and manufacturing overhead. Market is based on current replacement cost for raw materials and net realizable value for stores inventory and finished goods. • Raw material inventory includes material, chemicals and natural resources being used in the mining and refining process. • Finished goods inventory is the finished product soda ash. • Stores inventory includes parts, materials and operating supplies which are typically consumed in the production of soda ash and currently available for future use. Inventory expected to be consumed within the year is classified as current assets and remainder is classified as non-current assets. |
Property, Plant, and Equipment | Property, Plant, and Equipment Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of depreciable assets, using the straight-line method. The estimated useful lives applied to depreciable assets are as follows: Useful Lives Land improvements 10 years Depletable land 15-60 years Buildings and building improvements 10-30 years Internal-use computer software 3-5 years Machinery and equipment 5-20 years Furniture and fixtures 10 years The Partnership’s policy is to evaluate property, plant, and equipment for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. An indicator of potential impairment would include situations when the estimated future undiscounted cash flows are less than the carrying value. The amount of any impairment then recognized would be calculated as the difference between estimated fair value and the carrying value of the asset. |
Derivative Instruments and Hedging Activities | Derivative Instruments and Hedging Activities The Partnership may enter into derivative contracts from time to time to manage exposure to the risk of exchange rate changes on its foreign currency transactions, the risk of changes in natural gas prices, and the risk of the variability in interest rates on borrowings. Gains and losses on derivative contracts qualifying for hedge accounting are reported as a component of the underlying transactions. The Partnership follows hedge accounting for its hedging activities. All derivative instruments are recorded on the balance sheet at their fair values. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. The Partnership designates its derivatives based upon criteria established for hedge accounting under generally accepted accounting principles. For a derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with the offsetting gain or loss on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified into earnings when the hedged exposure affects earnings. Any significant ineffective portion of the gain or loss is reported in earnings immediately. For derivatives not designated as hedges, the gain or loss is reported in earnings in the period of change. The natural gas physical forward contracts are accounted for under the normal purchases and normal sales scope exception. |
Income Tax | Income Tax We are organized as a pass-through entity for federal income tax purposes and therefore are not subject to federal or certain state income taxes. As a result, our partners are responsible for federal income taxes based on their respective share of taxable income. Net income for financial statement purposes may differ significantly from taxable income reportable to unitholders as a result of differences between the tax basis and financial reporting basis of assets and liabilities and the taxable income allocation requirements under the partnership agreement. |
Technical Termination of the Partnership for U.S. Federal Income Tax Purposes | Technical Termination of the Partnership for U.S. Federal Income Tax Purposes In 2015, the Partnership experienced a technical termination as a result of the Transaction, which also resulted in a technical termination of Ciner Wyoming, for U.S. federal income tax purposes. The technical termination did not affect our consolidated financial statements nor did it affect our classification or Ciner Wyoming’s classification as a partnership or otherwise affect the nature or extent of our “qualifying income” for U.S. federal income tax purposes. Our 2015 taxable year for all then unitholders ended on October 23, 2015 and resulted in a deferral of depreciation deductions that were otherwise allowable in computing the taxable income of our unitholders. This deferral of depreciation deductions resulted in an increased taxable income (or reduced taxable loss) to certain of our unitholders in 2015. We did not view this deferral of depreciation deductions to have had a material adverse impact on our public common unitholders. |
Reclamation Costs | Reclamation Costs The Partnership is obligated to return the land beneath its refinery and tailings ponds to its natural condition upon completion of operations and is required to return the land beneath its rail yard to its natural condition upon termination of the various lease agreements. The Partnership accounts for its land reclamation liability as an asset retirement obligation, which requires that obligations associated with the retirement of a tangible long-lived asset be recorded as a liability when those obligations are incurred, with the amount of the liability initially measured at fair value. Upon initially recognizing a liability for an asset retirement obligation, an entity must capitalize the cost by recognizing an increase in the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the estimated useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. The estimated original liability calculated in 1996 for the refinery and tailing ponds was calculated based on the estimated useful life of the mine, which was 80 years , and on external and internal estimates as to the cost to restore the land in the future and state regulatory requirements. During 2017 , 2016 and 2015 , the remaining life was 66 , 67 and 68 years, respectively. In 2018 , the mining reserve will be amortized over a remaining life of 60 years. The decline in estimated mining reserves estimated remaining life is based on the results of a recent independent mine reserve analysis conducted as of December 31, 2017. The independent mine reserve analysis is routine and performed approximately every three years.The liability was discounted using a weighted average credit-adjusted risk-free rates of approximately 6% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold. During 2011 , the Partnership constructed a rail yard to facilitate loading and switching of rail cars. The Partnership is required to restore the land on which the rail yard is constructed to its natural conditions. The original estimated liability for restoring the rail yard to its natural condition was calculated based on the land lease life of 30 years and on external and internal estimates as to the cost to restore the land in the future. The liability is discounted using a credit-adjusted risk-free rate of 4.25% and is being accreted throughout the estimated life of the related assets to equal the total estimated costs with a corresponding charge being recorded to cost of products sold. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value is determined using a valuation hierarchy, generally by reference to an active trading market, quoted market prices or model-derived valuations for the same or similar financial instruments. See Note 17, “Fair Value Measurements,” for more information. |
Equity-Based Compensation | Equity-Based Compensation We recognize compensation expense related to equity-based awards, with service conditions, granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The grant date fair value of the equity-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. Equity-based awards with market conditions are fair valued using a Monte Carlo Simulation model. |
Subsequent Events | Subsequent Events We have evaluated subsequent events through the filing of this Annual Report on Form 10-K. |
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. The Partnership should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Partnership has completed its evaluation of the provisions of this ASU and does not expect our adoption of ASU 2014-09 to materially change the amount or timing of revenues recognized by us, nor expect it to materially affect our financial position. The majority of our revenues generated are recognized upon delivery and transfer of title to the product to our customers. The time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the product leaves our facility, thereby rendering our performance obligation fulfilled. The FASB issued various amendments to ASU 2014-09, one of which includes allowing entities to elect to account for shipping and handling activities performed after the control of a good has been transferred to the customer as a fulfillment cost versus an obligation of a promised service. The Partnership has made an accounting policy election upon adoption to account for shipping and handling activities as fulfillment costs, which is not expected to have a material impact on our financial statements. The Partnership adopted this ASU effective January 1, 2018, as permitted by the ASU, using the modified retrospective method. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining largely unchanged from current guidance. The update requires that lessees recognize a lease liability and a right of use asset for all leases (with the exception of short-term leases) at the commencement date of the lease and disclose key information about leasing arrangements. The update is effective for interim and annual periods beginning after December 15, 2018 and must be adopted using a modified retrospective transition. The ASU No. 2016-02 provides for certain practical expedients and early adoption is permitted. The Partnership is evaluating the potential impact the adoption of ASU No. 2016-02 will have on its consolidated financial statements. In August 2017, FASB issued ASU 2017-12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities. This ASU aims to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, this ASU make certain targeted improvements to simplify the application of the existing hedge accounting guidance. This ASU is effective for us beginning in the first quarter of 2019, with early application permitted. The Partnership is evaluating the effect the standard will have on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09–Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The updated guidance is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. We do not believe the updated requirements will materially impact the Partnership’s consolidated financial statements. |
