Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	1. General Description of Business SunCoke Energy, Inc. (“SunCoke Energy,” “SunCoke,” “Company,” “we,” “our” and “us”) is the largest independent producer of high-quality coke in the Americas, as measured by tons of coke produced each year, and has approximately 55 years of coke production experience. Coke is a principal raw material in the blast furnace steelmaking process and is produced by heating metallurgical coal in a refractory oven, which releases certain volatile components from the coal, thus transforming the coal into coke. Additionally, we own and operate a logistics business, which primarily provides handling and/or mixing services of coal and other aggregates to third-party customers as well as to our own cokemaking facilities. We have designed, developed, built, own and operate five cokemaking facilities in the United States (“U.S.”), which consist of our Haverhill Coke Company LLC ("Haverhill"), Middletown Coke Company, LLC ("Middletown"), Gateway Energy and Coke Company, LLC ("Granite City"), Jewell Coke Company, L.P. ("Jewell") and Indiana Harbor Coke Company ("Indiana Harbor") cokemaking facilities. Our cokemaking facilities have collective nameplate capacity to produce approximately 4.2 million tons of coke per year. Additionally, we have designed and operate one cokemaking facility in Brazil under licensing and operating agreements on behalf of ArcelorMittal Brasil S.A. ("ArcelorMittal Brazil”), which has approximately 1.7 million tons of annual cokemaking capacity. Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. This differs from by-product cokemaking, which repurposes the coal’s liberated volatile components for other uses. We have constructed the only greenfield cokemaking facilities in the U.S. in approximately 30 years and are the only North American coke producer that utilizes heat recovery technology in the cokemaking process. We provide steam pursuant to steam supply and purchase agreements with our customers. Electricity is sold into the regional power market or pursuant to energy sales agreements. Our logistics business provides handling and/or mixing services to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Our logistics business consists of Convent Marine Terminal ("CMT"), Kanawha River Terminals, LLC ("KRT"), SunCoke Lake Terminal, LLC ("Lake Terminal") and Dismal River Terminal, LLC ("DRT") and has collective capacity to mix and/or transload more than 40 million tons of coal and other aggregates annually and has total storage capacity of approximately 3 million tons. On June 27, 2018, we sold our 49 percent investment in VISA SunCoke Limited ("VISA SunCoke") for cash consideration of $4.0 million . Consequently, we recognized $9.0 million of accumulated currency translation losses and incurred $0.4 million of transaction costs, resulting in a net $5.4 million loss from equity method investment during the nine months ended September 30, 2018 on the Consolidated Statements of Operations. Our investment in VISA SunCoke was previously accounted for as an equity method investment and was fully impaired in 2015. Therefore, its financial results had not been included in our financial statements since that time. Our consolidated financial statements include SunCoke Energy Partners, L.P. (the "Partnership"), a publicly-traded partnership. At September 30, 2018 , we owned the general partner of the Partnership, which consists of a 2.0 percent ownership interest and incentive distribution rights, and owned a 60.4 percent limited partner interest in the Partnership. At September 30, 2018 , the remaining 37.6 percent interest in the Partnership was held by public unitholders. SunCoke is considered the primary beneficiary of the Partnership as it has the power to direct the activities that most significantly impact the Partnership's economic performance. Incorporated in Delaware in 2010 and headquartered in Lisle, Illinois, we became a publicly-traded company in 2011 and our stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “SXC.” Basis of Presentation The accompanying unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim reporting. Certain information and disclosures normally included in financial statements have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the periods ended September 30, 2018 are not necessarily indicative of the operating results expected for the entire year. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017 . Recently Adopted Accounting Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted this standard on January 1, 2018, using the modified retrospective method with no material impact on our revenue recognition model on an annual basis. See Note 14 . In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted cash.” The Company retrospectively adopted this ASU in the first quarter 2018 and modified the Company's cash flow presentation to include restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The restricted cash balance was zero at both September 30, 2018 and December 31, 2017, and was $0.4 million and $0.5 million at September 30, 2017 and December 31, 2016, respectively. Historical restricted cash balances were related to cash withheld from the 2015 acquisition of CMT to fund the completion of certain expansion capital improvements. In March 2017, the FASB issued ASU 2017-07, “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The Company adopted this ASU in the first quarter 2018 and retrospectively presented net periodic postretirement benefit cost in the income statement separately from the service cost component and outside a subtotal of income from operations. In conjunction with the adoption of this standard, expense of $0.4 million and $1.0 million was reclassified from operating income and was recorded in interest expense, net on the Consolidated Statements of Operations during the three and nine months ended September 30, 2017. See Note 7 . In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The Company adopted this ASU in the first quarter 2018 and reclassified $1.1 million of deferred tax adjustments to accumulated other comprehensive income (loss) from retained earnings on the December 31, 2017 balance sheet for the tax effects resulting from the Tax Cuts and Jobs Act of 2017. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires leases to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 842. This standard is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. We are implementing a technology tool to assist with the accounting and reporting requirements of this standard. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as land , the lease of our corporate office space and certain equipment rentals, will increase the reported assets and liabilities on our Consolidated Balance Sheets. The Company expects to prospectively adopt this standard on January 1, 2019. Reclassifications Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current year presentation.

Goodwill and Other Intangible Assets	3. Goodwill and Other Intangible Assets Goodwill, which represents the excess of the purchase price over the fair value of net assets acquired, is tested for impairment as of October 1 of each year, or when events occur or circumstances change that would, more likely than not, reduce the fair value of a reporting unit to below its carrying value. Goodwill allocated to our Domestic Coke and Logistics segments was $3.4 million and $73.5 million at both September 30, 2018 and December 31, 2017 , respectively. The components of other intangible assets, net were as follows: September 30, 2018 December 31, 2017 Weighted - Average Remaining Amortization Years Gross Carrying Amount Accumulated Amortization Net Gross Carrying Amount Accumulated Amortization Net (Dollars in millions) Customer contracts 4 $ 31.7 $ 16.6 $ 15.1 $ 31.7 $ 13.8 $ 17.9 Customer relationships 13 28.7 7.1 21.6 28.7 5.7 23.0 Permits 24 139.0 16.1 122.9 139.0 12.2 126.8 Trade name — 1.2 1.2 — 1.2 1.0 0.2 Total $ 200.6 $ 41.0 $ 159.6 $ 200.6 $ 32.7 $ 167.9 The permits above represent the environmental and operational permits required to operate a coal export terminal in accordance with the U.S. Environmental Protection Agency ("EPA") and other regulatory bodies. Intangible assets are amortized over their useful lives in a manner that reflects the pattern in which the economic benefit of the asset is consumed. The permits’ useful lives were estimated to be 27 years at acquisition based on the expected useful life of the significant operating equipment at the facility. We have historical experience of renewing and extending similar arrangements at our other facilities and intend to continue to renew our permits as they come up for renewal for the foreseeable future. The permits were renewed regularly prior to our acquisition of CMT. These permits have an average remaining renewal term of approximately 2.7 years. Total amortization expense for intangible assets subject to amortization was $2.7 million and $8.3 million for the three and nine months ended September 30, 2018 , respectively, and $2.8 million and $8.3 million for the three and nine months ended September 30, 2017 , respectively.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	4. Income Taxes At the end of each interim period, we make our best estimate of the effective tax rate expected to be applicable for the full fiscal year and the impact of discrete items, if any, and adjust the rate as necessary. The Company recorded an income tax benefit of $2.4 million for the three months ended September 30, 2018 and income tax expense of $1.8 million for the nine months ended September 30, 2018, respectively, resulting in effective tax rates of (16.0) percent and 3.7 percent , respectively, as compared to the 21.0 percent federal statutory rate. The difference in the Company’s effective tax rates as compared to the statutory rate was primarily the result of earnings attributable to its noncontrolling ownership interests in partnerships as well as a favorable adjustment to the valuation allowance associated with foreign tax credit carryforwards further discussed below. On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted. The Tax Legislation significantly revised the U.S. corporate income tax structure, including lowering corporate income tax rates. In addition, the SEC staff released Staff Accounting Bulletin 118 on December 23, 2017, which provided for companies to record a provisional impact of the Tax Legislation during a measurement period, not to exceed one year, in situations where companies do not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting under ASC 740 for certain income tax effects of the Tax Legislation for the reporting period which includes enactment. Based on an updated analysis of the foreign tax credit rules relating to the new Tax Legislation, the Company revised its estimate of the realizability of its foreign tax credits, resulting in a net $4.8 million benefit during the third quarter of 2018. As of September 30, 2018, there was a $9.2 million valuation allowance against $17.5 million of foreign tax credit carryforwards. There were no other significant changes to previous estimates and amounts recorded in 2017 relating to this Tax Legislation. The Company recorded an income tax benefit of $1.5 million for the three months ended September 30, 2017. The benefit was primarily due to the impact of earnings attributable to its noncontrolling interests in partnerships, partially offset by an increase in Illinois income tax rate effective July 2017. The Company recorded income tax expense of $69.4 million during the nine months ended September 30, 2017. Additionally, income tax expense during the nine months ended September 30, 2017 included the impacts of the Internal Revenue Service ("IRS") announcement of its final regulations on qualifying income in January 2017, discussed below. In January 2017, the IRS announced its decision to exclude cokemaking as a qualifying income generating activity in its final regulations (the "Final Regulations") issued under section 7704(d)(1)(E) of the Internal Revenue Code relating to the qualifying income exception for publicly traded partnerships. However, the Final Regulations include a transition period for activities that were reasonably interpreted to be qualifying income and carried on by publicly traded partnerships prior to the Final Regulations. The Partnership previously received a will-level opinion from its counsel, Vinson & Elkins LLP, that the Partnership's cokemaking operations generated qualifying income prior to the Final Regulations. Therefore, the Partnership believes it had a reasonable basis to conclude its cokemaking operations were considered qualifying income before the issuance of the new regulations and as such expects to maintain its treatment as a partnership through the transition period. Cokemaking entities in the Partnership will become taxable as corporations on January 1, 2028, after the transition period ends.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	8. Commitments and Contingent Liabilities Legal Matters SunCoke Energy is party to an omnibus agreement, pursuant to which we have agreed to indemnify the Partnership for costs and expenses related to remediation of certain identified environmental matters in existence prior to the Partnership's initial public offering on January 24, 2013 ("IPO") at the Partnership’s Haverhill and Middletown facilities and certain identified environmental matters at the Partnership's Granite City facility in existence prior to its dropdown in January of 2015 ("Granite City Dropdown"). However, under the terms of the omnibus agreement, SunCoke Energy is not obligated to indemnify the Partnership for any new environmental matters coming into existence after the IPO at the Partnership’s Haverhill and Middletown facilities, or any new environmental matters coming into existence after the Granite City Dropdown at the Partnership's Granite City facility. The EPA issued Notices of Violations (“NOVs”) for our Haverhill and Granite City cokemaking facilities which stemmed from alleged violations of our air emission operating permits for these facilities. We are working in a cooperative manner with the EPA, the Ohio Environmental Protection Agency and the Illinois Environmental Protection Agency to address the allegations, and have entered into a consent decree in federal district court with these parties. The consent decree includes a $2.2 million civil penalty payment, which was paid in December 2014, as well as capital projects underway to improve the reliability of the energy recovery systems and enhance environmental performance at the Haverhill and Granite City facilities . An amendment was lodged in February 2018 and entered by the federal district court in July 2018. The amendment provides the Haverhill and Granite City facilities with additional time to perform necessary maintenance on the flue gas desulfurization systems without exceeding consent decree limits. The emissions associated with this maintenance will be mitigated in accordance with the amendment, and there are no civil penalty payments associated with this amendment. The project at Granite City was due to be completed in February 2019, but the Company now expects to complete the project in July 2019 and is in discussions with the government entities regarding, among other things, the timing thereof. We anticipate spending approximately $150 million related to these projects, of which we have spent approximately $132 million to date, including $7 million spent by the Company prior to the formation of the Partnership. The remaining capital is expected to be spent through the first half of 2019. A portion of the proceeds from the Partnership's initial public offering and subsequent dropdowns were used to fund $119 million of these environmental remediation projects. Pursuant to the omnibus agreement, the Company made a capital contribution to the Partnership of $10 million during the first quarter of 2018 for these known environmental remediation projects. The Company expects to make additional capital contributions to the Partnership of approximately $10 million in the fourth quarter of 2018 and approximately $5 million in the first half of 2019 for the estimated future spending related to these environmental remediation projects. SunCoke Energy has also received NOVs, Findings of Violations ("FOVs"), and information requests from the EPA related to our Indiana Harbor cokemaking facility, which allege violations of certain air operating permit conditions for this facility. The Clean Air Act (the "CAA") provides the EPA with the authority to issue, among other actions, an order to enforce a State Implementation Plan ("SIP") 30 days after an NOV. The CAA also authorizes EPA enforcement of other non-SIP requirements immediately after an FOV. Generally, an NOV applies to SIPs and requires the EPA to wait 30 days, while an FOV applies to all other provisions (such as federal regulations) of the CAA, and has no waiting period. The NOVs and/or FOVs were received in 2010, 2012, 2013, 2015 and 2016. After discussions with the EPA and the Indiana Department of Environmental Management (“IDEM”) in 2010, resolution of the NOVs/FOVs was postponed by mutual agreement because of ongoing discussions regarding the NOVs at Haverhill and Granite City. In January 2012, the Company began working in a cooperative manner to address the allegations with the EPA, the IDEM and Cokenergy, LLC, an independent power producer that owns and operates an energy facility, including heat recovery equipment and a flue gas desulfurization system, that processes hot flue gas from our Indiana Harbor facility to produce steam and electricity and to reduce the sulfur and particulate content of such flue gas. The EPA, IDEM, SunCoke Energy and Cokenergy, LLC have met regularly since those discussions commenced, and continued to meet regularly in 2017 to reach a settlement of the NOVs and FOVs. Capital projects were underway during this time to address items that would be included in conjunction with a settlement of the NOVs/FOVs. A consent decree among the parties was lodged in federal court in January 2018 and is undergoing review. The settlement includes a $2.5 million civil penalty payment, which is included in accrued liabilities on the Consolidated Balance Sheets at both September 30, 2018 and December 31, 2017. Further, the settlement consists of capital projects already underway to improve reliability and environmental performance of the coke ovens at the facility. The Company is a party to certain other pending and threatened claims, including matters related to commercial and tax disputes, product liability, employment claims, personal injury claims, premises-liability claims, allegations of exposures to toxic substances and environmental claims. Although the ultimate outcome of these claims cannot be ascertained at this time, it is reasonably possible that some portion of these claims could be resolved unfavorably to the Company. Management of the Company believes that any liability which may arise from claims would not have a material adverse impact on our consolidated financial statements. Black Lung Benefit Liabilities The Company has obligations related to coal workers’ pneumoconiosis, or black lung, benefits to certain of our former coal miners and their dependents. Such benefits are provided for under Title IV of the Federal Coal Mine and Safety Act of 1969 and subsequent amendments, as well as for black lung benefits provided in the states of Virginia, Kentucky and West Virginia pursuant to workers’ compensation legislation. The Patient Protection and Affordable Care Act (“PPACA”), which was implemented in 2010, amended previous legislation related to coal workers’ black lung obligations. PPACA provides for the automatic extension of awarded lifetime benefits to surviving spouses and changes the legal criteria used to assess and award claims. We act as a self-insurer for both state and federal black lung benefits and adjust our liability each year based upon actuarial calculations of our expected future payments for these benefits. Our independent actuarial consultants calculate the present value of the estimated black lung liability annually based on actuarial models utilizing our population of former coal miners, historical payout patterns of both the Company and the industry, actuarial mortality rates, disability incidence, medical costs, death benefits, dependents, discount rates and the current federally mandated payout rates. The estimated liability may be impacted by future changes in the statutory mechanisms, modifications by court decisions and changes in filing patterns driven by perceptions of success by claimants and their advisors, the impact of which cannot be estimated. The estimated liability was $51.3 million and $50.3 million at September 30, 2018 and December 31, 2017 , respectively, of which the current portion of $5.4 million was included in accrued liabilities on the Consolidated Balance Sheets in both periods.

Share-Based Compensation	9. Share-Based Compensation Equity Classified Awards During the nine months ended September 30, 2018 , the Company granted share-based compensation to eligible participants under the SunCoke Energy, Inc. Long-Term Performance Enhancement Plan (“SunCoke LTPEP”). All awards vest immediately upon a change in control and a qualifying termination of employment as defined by the SunCoke LTPEP. Stock Options The Company granted the following stock options during the nine months ended September 30, 2018 with an exercise price equal to the closing price of our common stock on the date of grant. Weighted Average Per Share Shares Exercise Price Grant Date Fair Value Traditional stock options 78,447 $ 10.49 $ 5.38 The stock options vest in three equal annual installments beginning one year from the date of grant. The stock options expire ten years from the date of grant. The Company calculates the value of each employee stock option, estimated on the date of grant, using the Black-Scholes option pricing model. The weighted-average fair value of employee stock options granted during the nine months ended September 30, 2018 was based on using the following weighted-average assumptions: Nine Months Ended September 30, 2018 Risk-free interest rate 3 % Expected term 6 years Volatility 52 % Dividend yield — % The risk-free interest rate assumption is based on the U.S. Treasury yield curve at the date of grant for periods which approximate the expected life of the option. The expected term of the employee options represent the average contractual term adjusted by the average vesting period of each option tranche. We determined expected volatility using our historical volatility calculated as our historical daily stock returns over the options' expected term. The dividend yield assumption is based on the Company’s expectation of dividend payouts at the time of grant. Restricted Stock Units Settled in Shares The Company issued 32,128 stock-settled restricted stock units (“RSUs”) to certain employees for shares of the Company’s common stock during the nine months ended September 30, 2018 . The weighted average grant date fair value was $10.49 per share. The RSUs vest in three annual installments beginning one year from the date of grant. Performance Share Units The Company granted the following performance share units ("PSUs") for shares of the Company's common stock during the nine months ended September 30, 2018 that vest on December 31, 2020 : Shares Grant Date Fair Value per Share PSUs (1)(2) 96,389 $ 11.36 (1) The PSU awards are split 50 /50 between the Company's three year cumulative Adjusted EBITDA performance measure and the Company's three -year average pre-tax return on capital performance measure for its coke and logistics businesses and unallocated corporate expenses. (2) The number of PSUs ultimately awarded will be determined by the above performance versus targets and the Company's three -year total shareholder return ("TSR") as compared to the TSR of the companies making up the Nasdaq Iron & Steel Index ("TSR Modifier"). The TSR Modifier can impact the payout between 75 percent and 125 percent of the Company's final performance measure results. The award may vest between zero and 250 percent of the original units granted. In the event the TSR performance is negative, the overall payout of the award shall be capped at 100 percent . The fair value of the PSUs granted during the nine months ended September 30, 2018 is based on the closing price of our common stock on the date of grant as well as a Monte Carlo simulation for the valuation of the TSR Modifier. Liability Classified Awards Restricted Stock Units Settled in Cash During the nine months ended September 30, 2018 , the Company issued 108,522 restricted stock units to be settled in cash ("Cash RSUs"), which vest in three annual installments beginning one year from the grant date. The weighted average grant date fair value of the Cash RSUs granted during the nine months ended September 30, 2018 was $10.71 and was based on the closing price of our common stock on the day of grant. The Cash RSU liability is adjusted based on the closing price of our common stock at the end of each period and at both September 30, 2018 and December 31, 2017 was not material. Cash Incentive Award The Company also granted share-based compensation to eligible participants under the SunCoke Energy, Inc.

The Company issued a grant date fair value award of $1.0 million during the nine months ended September 30, 2018 that vest on December 31, 2020 . The awards are split 50 /50 between the Company's three -year cumulative Adjusted EBITDA performance and the Company's three -year average pre-tax return on capital for its coke and logistics businesses and unallocated corporate expenses. The ultimate award value will be determined by the performance versus targets and the Company's three -year TSR Modifier performance but will be capped at 250 percent of the target award. The cash incentive award liability at September 30, 2018 was adjusted based on the Company's three -year cumulative Adjusted EBITDA performance and adjusted average pre-tax return on capital for the Company's coke and logistics businesses and unallocated corporate expenses. The cash incentive award liability at both September 30, 2018 and December 31, 2017 was not material.

Fair Value Measurement

Fair Value Measurement	9 Months Ended
	Sep. 30, 2018
Fair Value Disclosures [Abstract]
Fair Value Measurement	13. Fair Value Measurement The Company 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 from the sale of 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. The 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 Assets and Liabilities Measured at Fair Value on a Recurring Basis Certain assets and liabilities are measured at fair value on a recurring basis. The Company's cash equivalents, which amounted to $6.6 million and $5.5 million at September 30, 2018 and December 31, 2017 , respectively, were measured at fair value based on quoted prices in active markets for identical assets. These inputs are classified as Level 1 within the valuation hierarchy. CMT Contingent Consideration In connection with the CMT acquisition, the Partnership entered into a contingent consideration arrangement that requires the Partnership to make future payments to The Cline Group based on future volume over a specified threshold, price and contract renewals. The fair value of the contingent consideration was estimated based on a probability-weighted analysis using significant inputs that are not observable in the market, or Level 3 inputs. Key assumptions included probability adjusted levels of handling services provided by CMT, anticipated price per ton on future sales and probability of contract renewal, including length of future contracts, volume commitment, and anticipated price per ton. The fair value of the contingent consideration was $3.6 million at September 30, 2018 , with $0.9 million included in accrued liabilities and $2.7 million included in other deferred credit and liabilities on the Consolidated Balance Sheets. The fair value of the contingent consideration was $2.5 million at December 31, 2017 and was included in other deferred credits and liabilities on the Consolidated Balance Sheets. The increase in the fair value of the contingent consideration liability was primarily due to changes in expected throughput volumes related to the long-term, take-or-pay agreements. Certain Financial Assets and Liabilities not Measured at Fair Value At September 30, 2018 and December 31, 2017 , the fair value of the Company’s total debt was estimated to be $908.9 million and $919.7 million , respectively, compared to a carrying amount of $ 859.9 million and $887.3 million , respectively. The fair value was estimated by management based upon estimates of debt pricing provided by financial institutions, which are considered Level 2 inputs.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	14. Revenue from Contracts with Customers Cokemaking Substantially all our coke sales are made pursuant to long-term, take-or-pay agreements with ArcelorMittal USA LLC and/or its affiliates (“AM USA”), AK Steel Holding Corporation ("AK Steel") and United States Steel Corporation ("U.S. Steel"), who are three of the largest blast furnace steelmakers in North America. The take-or-pay provisions of our agreements require us to deliver minimum annual tonnage, which varies by contract, but covers at least 90 percent of each facility's annual capacity. The take-or-pay provisions also require our customers to purchase such volumes of coke or pay the contract price for any tonnage they elect not to take. These coke sales agreements have an average remaining term of approximately six years, and to date, our coke customers have satisfied their obligations under these agreements. Our coke sales prices include an operating cost component, a coal cost component and a return of capital component. Operating costs under two of our coke sales agreements are contractual, subject to an annual adjustment based on an inflation index. Under our other four coke sales agreements operating costs are passed through to the respective customers subject to an annually negotiated budget, in some cases subject to a cap annually adjusted for inflation, and generally we share any difference in costs from the budgeted amounts with our customers. Our coke sales agreements contain pass-through provisions for coal and coal procurement costs, subject to meeting contractual coal-to-coke yields. To the extent that the actual coal-to-coke yields are less than the contractual standard, we are responsible for the cost of the excess coal used in the cokemaking process. Conversely, to the extent our actual coal-to-coke yields are higher than the contractual standard, we realize gains. The reimbursement of pass-through operating and coal costs from these coke sales agreements are considered to be variable consideration components included in the cokemaking sales price. The return of capital component for each ton of coke sold to the customer is determined at the time the coke sales agreement is signed and is effective for the term of each sales agreement. This component of our coke sales prices is intended to provide an adequate return on invested capital and may differ based on investment levels and other considerations. The actual return on invested capital at any facility is also impacted by favorable or unfavorable performance on pass-through cost items. Revenues are recognized when performance obligations to our customers are satisfied in an amount that reflects the consideration that we expect to receive in exchange for the coke. Logistics In our logistics business, handling and/or mixing services are provided to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take possession of materials handled, but rather act as intermediaries between our customers and end users, deriving our revenues from services provided on a per ton basis. The handling and mixing services consist primarily of two performance obligations, unloading and loading of materials. Our logistics business has long-term, take-or-pay agreements requiring us to handle over 13 million tons annually. The take-or-pay provisions in these agreements require our customers to purchase such handling services or pay the contract price for services they elect not to take. Estimated take-or-pay revenue of approximately $320 million from all of our long-term logistics contracts is expected to be recognized over the next five years for unsatisfied or partially unsatisfied performance obligations as of September 30, 2018 . To date, our customers have satisfied their obligations under these agreements. Included with these long-term, take-or-pay arrangements are our contracts with Murray American Coal, Inc. ("Murray") and Foresight Energy LLC ("Foresight"), which cover 10 million tons of CMT's annual transloading capacity of 15 million tons. Revenues are recognized when the customer receives the benefits of the services provided, in an amount that reflects the consideration that we will receive in exchange for those services. Billings to CMT customers for take-or-pay volume shortfalls based on pro-rata volume commitments under take-or-pay contracts that are in excess of billings earned for services provided are recorded as contract liabilities and characterized as deferred revenue on the Consolidated Balance Sheets. Deferred revenue is recognized at the earliest of i) when the performance obligation is satisfied; ii) when the performance obligation has expired, based on the terms of the contract; or iii) when the likelihood that the customer would exercise its right to the performance obligation becomes remote. The following table provides changes in the Company's deferred revenue: 2018 2017 (Dollars in millions) Beginning balance at December 31, 2017 and 2016, respectively $ 1.7 $ 2.5 Reclassification of the beginning contract liabilities to revenue, as a result of performance obligation satisfied (1.4 ) (2.1 ) Billings in excess of services performed, not recognized as revenue 2.3 16.2 Ending balance at September 30, 2018 and 2017, respectively $ 2.6 $ 16.6 Energy Our energy sales are made pursuant to either steam or energy supply and purchase agreements or is sold into the regional power market. Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. The energy provided under these arrangements result in transfer of control over time. Revenues are recognized over time as energy is delivered to our customers, in an amount based on the terms of each arrangement. Operating and Licensing Fees Operating and licensing fees are made pursuant to long-term contracts with ArcelorMittal Brazil, where we operate a Brazilian cokemaking facility. The licensing fees are based upon the level of production required by our customer as well as a fixed annual fee. Operating fees include the full pass-through of the operating costs of the Brazilian facility as well as a per ton fee based on the level of production required by our customer. Revenues are recognized over time as our customers receive and consume the benefits in an amount that corresponds directly with the value provided to the customer to date.

Segment Reporting [Abstract]
Business Segment Information	15. Business Segment Information The Company reports its business through three segments: Domestic Coke, Brazil Coke and Logistics. The Domestic Coke segment includes the Jewell, Indiana Harbor, Haverhill, Granite City and Middletown cokemaking facilities. Each of these facilities produces coke, and all facilities except Jewell recover waste heat, which is converted to steam or electricity through a similar production process. The Brazil Coke segment includes the licensing and operating fees payable to us under long-term contracts with ArcelorMittal Brazil, under which we operate a cokemaking facility located in Vitória, Brazil through at least 2023 . Logistics operations are comprised of CMT, KRT, Lake Terminal, which provides services to our Indiana Harbor cokemaking facility, and DRT, which provides services to our Jewell cokemaking facility. Handling and mixing results are presented in the Logistics segment. Corporate expenses that can be identified with a segment have been included in determining segment results. The remainder is included in Corporate and Other. Corporate and Other also includes activity from our legacy coal mining business, which was historically presented as a separate reportable segment. Segment assets are those assets utilized within a specific segment and exclude deferred taxes and current tax receivables. The following table includes Adjusted EBITDA, which is the measure of segment profit or loss and liquidity reported to the chief operating decision maker for purposes of allocating resources to the segments and assessing their performance: Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 (Dollars in millions) Sales and other operating revenue: Domestic Coke $ 326.8 $ 309.7 $ 973.6 $ 884.9 Brazil Coke 9.7 10.9 30.0 32.2 Logistics 28.0 18.4 78.4 54.8 Logistics intersegment sales 5.7 4.8 16.6 15.0 Elimination of intersegment sales (5.7 ) (4.8 ) (16.6 ) (15.0 ) Total sales and other operating revenues $ 364.5 $ 339.0 $ 1,082.0 $ 971.9 Adjusted EBITDA: Domestic Coke $ 49.1 $ 55.6 $ 156.3 $ 149.3 Brazil Coke 4.5 4.6 14.0 13.5 Logistics 21.0 12.6 54.3 35.7 Corporate and Other (1) (8.6 ) (10.7 ) (27.3 ) (33.3 ) Total Adjusted EBITDA $ 66.0 $ 62.1 $ 197.3 $ 165.2 Depreciation and amortization expense: Domestic Coke (2) $ 28.7 $ 24.0 $ 79.5 $ 77.4 Brazil Coke 0.2 0.2 0.5 0.5 Logistics 6.2 6.1 19.2 18.3 Corporate and Other 0.3 0.3 1.1 1.0 Total depreciation and amortization expense $ 35.4 $ 30.6 $ 100.3 $ 97.2 Capital expenditures: Domestic Coke $ 25.1 $ 26.0 $ 67.1 $ 45.9 Logistics 1.9 0.5 3.5 1.8 Corporate and Other — 0.7 0.1 1.9 Total capital expenditures $ 27.0 $ 27.2 $ 70.7 $ 49.6 (1) Corporate and Other includes the activity from our legacy coal mining business, which contributed Adjusted EBITDA losses of $2.9 million and $7.6 million during the three and nine months ended September 30, 2018 , respectively, as well as $2.0 million and $8.2 million during the three and nine months ended September 30, 2017 , respectively. (2) We revised the estimated useful lives of certain assets in our Domestic Coke segment, primarily as a result of plans to replace major components of certain heat recovery steam generators with upgraded materials and design, resulting in additional depreciation of $2.7 million , or $0.04 per common share, during both the three and nine months ended September 30, 2018 . The following table sets forth the Company's segment assets: September 30, 2018 December 31, 2017 (Dollars in millions) Segment assets Domestic Coke $ 1,474.8 $ 1,439.7 Brazil Coke 14.7 10.9 Logistics 473.7 491.9 Corporate and Other 132.3 112.8 Segment assets, excluding income tax receivable 2,095.5 2,055.3 Income tax receivable 2.7 4.8 Total assets $ 2,098.2 $ 2,060.1 The Company evaluates the performance of its segments based on segment Adjusted EBITDA, which is defined as earnings before interest, taxes, depreciation and amortization ("EBITDA"), adjusted for any impairments, loss (gain) on extinguishment of debt, changes to our contingent consideration liability related to our acquisition of CMT and/or loss on the disposal of our interest in VISA SunCoke. EBITDA and Adjusted EBITDA do not represent and should not be considered alternatives to net income or operating income under GAAP and may not be comparable to other similarly titled measures in other businesses. Management believes Adjusted EBITDA is an important measure of the operating performance and liquidity of the Company's net assets and its ability to incur and service debt, fund capital expenditures and make distributions. Adjusted EBITDA provides useful information to investors because it highlights trends in our business that may not otherwise be apparent when relying solely on GAAP measures and because it eliminates items that have less bearing on our operating performance and liquidity. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, and they should not be considered a substitute for net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. Set forth below is additional discussion of the limitations of Adjusted EBITDA as an analytical tool. Limitations. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Adjusted EBITDA also has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of our results as reported under GAAP. Some of these limitations include that Adjusted EBITDA: • does not reflect our cash expenditures, or future requirements, for capital expenditures or contractual commitments; • does not reflect items such as depreciation and amortization; • does not reflect changes in, or cash requirement for, working capital needs; • does not reflect our interest expense, or the cash requirements necessary to service interest on or principal payments of our debt; • does not reflect certain other non-cash income and expenses; • excludes income taxes that may represent a reduction in available cash; and • includes net income attributable to noncontrolling interests. Below is a reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities, which are its most directly comparable financial measures calculated and presented in accordance with GAAP: Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 (Dollars in millions) Net cash provided by operating activities $ 85.3 $ 73.9 $ 170.6 $ 128.3 Subtract: Depreciation and amortization expense 35.4 30.6 100.3 97.2 Deferred income tax (benefit) expense (4.3 ) (9.4 ) (4.0 ) 70.4 Loss on extinguishment of debt — 0.1 0.3 20.4 Loss from equity method investment — — 5.4 — Changes in working capital and other 37.1 33.8 27.1 10.7 Net income (loss) $ 17.1 $ 18.8 $ 41.5 $ (70.4 ) Add: Depreciation and amortization expense $ 35.4 $ 30.6 $ 100.3 $ 97.2 Interest expense, net (1) 15.4 16.1 46.9 45.0 Loss on extinguishment of debt — 0.1 0.3 20.4 Income tax (benefit) expense (2.4 ) (1.5 ) 1.8 69.4 Contingent consideration adjustments 0.5 (2.0 ) 1.1 (1.7 ) Loss from equity method investment — — 5.4 — Expiration of land deposits and write-off of costs related to potential new cokemaking facility (2) — — — 5.3 Adjusted EBITDA $ 66.0 $ 62.1 $ 197.3 $ 165.2 Subtract: Adjusted EBITDA attributable to noncontrolling interests (3) 21.0 21.9 61.6 61.0 Adjusted EBITDA attributable to SunCoke Energy, Inc. $ 45.0 $ 40.2 $ 135.7 $ 104.2 (1) In conjunction with the adoption of ASU 2017-07, the non-service type expense associated with the postretirement benefit plans was excluded from operating income and recorded in interest expense, net on the Consolidated Statements of Operations during the periods presented. Amounts in prior periods were immaterial, and therefore, were not reclassified in the reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities. (2) During the second quarter of 2017, the Company wrote-off previously capitalized engineering and land deposit costs of $5.3 million .

Condensed Financial Information Disclosure [Abstract]
Supplemental Condensed Consolidating Financial Information	16. Supplemental Condensed Consolidating Financial Information Certain 100 percent owned subsidiaries of the Company serve as guarantors of the obligations under the Credit Agreement (“Guarantor Subsidiaries”). These guarantees are full and unconditional (subject, in the case of the Guarantor Subsidiaries, to customary release provisions as described below) and joint and several. For purposes of the following information, SunCoke Energy is referred to as “Issuer.” The indenture dated July 26, 2011 among the Company, the guarantors party thereto and The Bank of New York Mellon Trust Company, N.A., governs subsidiaries designated as “Guarantor Subsidiaries.” All other consolidated subsidiaries of the Company are collectively referred to as “Non-Guarantor Subsidiaries.” The ability of the Partnership and Indiana Harbor to pay dividends and make loans to the Company is restricted under the partnership agreements of the Partnership and Indiana Harbor, respectively. The credit agreement governing the Partnership’s credit facility and the indenture governing the Partnership Notes contain customary provisions which would potentially restrict the Partnership’s ability to make distributions or loans to the Company under certain circumstances. For the year ended December 31, 2017, less than 25 percent of net assets were restricted. Additionally, certain coal mining entities are designated as unrestricted subsidiaries. As such, all the subsidiaries described above are presented as "Non-Guarantor Subsidiaries." There have been no changes to the "Guarantor Subsidiaries" and "Non-Guarantor Subsidiaries" during 2018. The guarantee of a Guarantor Subsidiary will terminate upon: • a sale or other disposition of the Guarantor Subsidiary or of all or substantially all of its assets; • a sale of the majority of the Capital Stock of a Guarantor Subsidiary to a third-party, after which the Guarantor Subsidiary is no longer a "Restricted Subsidiary" in accordance with the indenture governing the Notes; • the liquidation or dissolution of a Guarantor Subsidiary so long as no "Default" or "Event of Default", as defined under the indenture governing the Notes, has occurred as a result thereof; • the designation of a Guarantor Subsidiary as an "unrestricted subsidiary" in accordance with the indenture governing the Notes; • the requirements for defeasance or discharge of the indentures governing the Notes having been satisfied; or • the release, other than the discharge through payments by a Guarantor Subsidiary, from its guarantee under the Credit Agreement or other indebtedness that resulted in the obligation of the Guarantor Subsidiary under the indenture governing the Notes. The following supplemental condensed combining and consolidating financial information reflects the Issuer’s separate accounts, the combined accounts of the Guarantor Subsidiaries, the combined accounts of the Non-Guarantor Subsidiaries, the combining and consolidating adjustments and eliminations and the Issuer’s consolidated accounts for the dates and periods indicated.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recently Adopted Accounting Pronouncements and Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In May 2014, Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, “Revenue from Contracts with Customers (Topic 606),” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company adopted this standard on January 1, 2018, using the modified retrospective method with no material impact on our revenue recognition model on an annual basis. See Note 14 . In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted cash.” The Company retrospectively adopted this ASU in the first quarter 2018 and modified the Company's cash flow presentation to include restricted cash with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The restricted cash balance was zero at both September 30, 2018 and December 31, 2017, and was $0.4 million and $0.5 million at September 30, 2017 and December 31, 2016, respectively. Historical restricted cash balances were related to cash withheld from the 2015 acquisition of CMT to fund the completion of certain expansion capital improvements. In March 2017, the FASB issued ASU 2017-07, “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The Company adopted this ASU in the first quarter 2018 and retrospectively presented net periodic postretirement benefit cost in the income statement separately from the service cost component and outside a subtotal of income from operations. In conjunction with the adoption of this standard, expense of $0.4 million and $1.0 million was reclassified from operating income and was recorded in interest expense, net on the Consolidated Statements of Operations during the three and nine months ended September 30, 2017. See Note 7 . In February 2018, the FASB issued ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The Company adopted this ASU in the first quarter 2018 and reclassified $1.1 million of deferred tax adjustments to accumulated other comprehensive income (loss) from retained earnings on the December 31, 2017 balance sheet for the tax effects resulting from the Tax Cuts and Jobs Act of 2017. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires leases to be recognized as assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. Subsequently, the FASB has issued various ASUs to provide further clarification around certain aspects of ASC 842. This standard is effective for annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. A multi-disciplined implementation team has gained an understanding of the accounting and disclosure provisions of the standard and is in the process of analyzing the impacts to our business, including the development of new accounting processes to account for our leases and support the required disclosures. We are implementing a technology tool to assist with the accounting and reporting requirements of this standard. While we are still evaluating the impact of adopting this standard, we expect that upon adoption the right-of-use assets and lease liabilities, such as land , the lease of our corporate office space and certain equipment rentals, will increase the reported assets and liabilities on our Consolidated Balance Sheets. The Company expects to prospectively adopt this standard on January 1, 2019.
