Accounting Policies [Abstract]
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	Note 1. Organization, Operations and Basis of Presentation Description of Business AdvanSix Inc. (“AdvanSix”, the “Business”, the “Company”, “we” or “our”) is an integrated manufacturer of Nylon 6, a polymer resin which is a synthetic material used by our customers to produce engineered plastics, fibers, filaments and films that, in turn, are used in such end-products as automotive and electronic components, carpets, sports apparel, fishing nets and food and industrial packaging. As a result of our backward integration and the configuration of our manufacturing facilities, we also sell a variety of other products, all of which are produced as part of the Nylon 6 resin manufacturing process including caprolactam, ammonium sulfate fertilizers, and other chemical intermediates. All of our manufacturing plants and operations are located in the United States. We serve approximately 500 customers globally located in more than 40 countries. For the years ended December 31, 2016, 2015 and 2014, we had sales of $1,191.5 million, $1,329.4 million and $1,790.4 million, respectively, and net income of $34.1 million, $63.8 million and $83.9 million, respectively. For the years ended December 31, 2016, 2015 and 2014, our sales to customers located outside the United States were $216.4 million, $355.8 million and $502.3 million, respectively. Each of these product lines represented the following approximate percentage of our sales: Years Ended December 31, 2016 2015 2014 Nylon 28% 27% 25% Caprolactam 17% 18% 21% Ammonium Sulfate Fertilizers 24% 25% 20% Chemical Intermediates 31% 30% 34% We evaluated segment reporting in accordance with Accounting Standards Codification Topic (“ASC”) 280. We concluded that AdvanSix is a single operating segment and a single reportable segment based on the operating results available which are evaluated regularly by the chief operating decision maker (“CODM”) to make decisions about resource allocation and performance assessment. AdvanSix operations are managed as one integrated process spread across three manufacturing sites, including centralized supply chain and procurement functions. The production process is dependent upon one key raw material, cumene, as the input to the manufacturing of all finished goods produced for sale through the sales channels and end-markets the Business serves. Production rates and output volumes are managed across all three plants jointly to align with the overall Business operating plan. The CODM makes operational performance assessments and resource allocation decisions on a consolidated basis, inclusive of all of the Business’s products. AdvanSix is primarily located in North America, operating through three integrated manufacturing sites located in Frankford, Pennsylvania, Hopewell, Virginia and Chesterfield, Virginia. Separation from Honeywell On October 1, 2016, Honeywell International Inc. (“Honeywell”) completed the previously announced separation of AdvanSix. The separation was completed by Honeywell distributing all of the then outstanding shares of common stock of AdvanSix on October 1, 2016 (the “Distribution Date”) through a dividend in kind of AdvanSix common stock, par value $0.01, to holders of Honeywell common stock as of the close of business on the record date of September 16, 2016 who held their shares through the Distribution Date (the “Spin-Off”). Each Honeywell stockholder who held their shares through the Distribution Date received one share of AdvanSix common stock for every 25 shares of Honeywell common stock held at the close of business on the record date of September 16, 2016. The separation was completed pursuant to a Separation and Distribution Agreement and other agreements with Honeywell related to the separation, including an Employee Matters Agreement, a Tax Matters Agreement and a Transition Services Agreement, each of which was filed as an exhibit to our Current Report on Form 8-K, filed with the Securities and Exchange Commission (“SEC”) on September 28, 2016, as well as Site Sharing and Services Agreements for facilities located in Chesterfield, Colonial Heights and Pottsville, each of which was filed as an exhibit to our Current Report on Form 8-K, filed with the SEC on October 3, 2016. These agreements govern the relationship between AdvanSix and Honeywell following the separation and provide for the allocation of various assets, liabilities, rights and obligations. These agreements also include arrangements for transition services to be provided by Honeywell to AdvanSix and by AdvanSix to Honeywell. A description of the material terms and conditions of these agreements can be found in the section titled “Certain Relationships and Related Party Transactions” of the Company’s Information Statement filed as Exhibit 99.1 to Amendment No. 5 to the Registration Statement of AdvanSix Inc. on Form 10 dated and filed with the SEC on September 7, 2016 and declared effective by the SEC on September 8, 2016 (the “Form 10”). On October 3, 2016, AdvanSix stock began “regular-way” trading on the New York Stock Exchange under the “ASIX” stock symbol. Basis of Presentation Prior to the separation, these Consolidated and Combined Financial Statements were derived from the consolidated financial statements and accounting records of Honeywell. These Consolidated and Combined Financial Statements reflect the consolidated historical results of operations, financial position and cash flows of AdvanSix as they were historically managed in conformity with GAAP. All intracompany transactions have been eliminated. As described in Note 3, all significant transactions between the Business and Honeywell prior to separation have been included in these Consolidated and Combined Financial Statements and are considered to be effectively settled for cash at the time the transaction was recorded. The total net effect of the settlement of these pre-separation transactions is reflected in the Consolidated and Combined Statements of Cash Flows as a financing activity and in the Consolidated and Combined Balance Sheets as invested equity. Prior to the Spin-Off, Honeywell provided certain services, such as legal, accounting, information technology, human resources and other infrastructure support, on behalf of the Business. The cost of these services has been allocated to the Business on a direct usage basis when identifiable, with the remainder allocated on the basis of revenues, headcount or other relevant measures. However, the financial information presented in these Consolidated and Combined Financial Statements may not reflect the financial position, operating results and cash flows of the Business had the Business been a separate stand-alone entity during the periods presented. Actual costs that would have been incurred if the Business had been a stand-alone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. Both we and Honeywell consider the basis on which the expenses have been allocated to be a reasonable reflection of the utilization of services provided to or the benefits received by the Business during the periods presented. After the Spin-Off, a number of the above services will continue under a transition service agreement with Honeywell, which we will expense as incurred based on the contractual pricing terms.

Differences between tax positions taken or expected to be taken in a tax return and the benefit recognized and measured pursuant to the interpretation are referred to as “unrecognized benefits”. A liability is recognized (or amount of net operating loss carryover or amount of tax refundable is reduced) for an unrecognized tax benefit because it represents an enterprise’s potential future obligation to the taxing authority for a tax position that was not recognized as a result of applying the provisions of ASC 740. Interest costs and related penalties related to unrecognized tax benefits are required to be calculated, if applicable. Our policy is to classify tax related interest and penalties, if any, as a component of income tax expense. No interest or penalties were recorded during the years ended December 31, 2016 and 2015. As of December 31, 2016 and December 31, 2015, no liability for unrecognized tax benefits was required to be reported. We do not expect any significant changes in our unrecognized tax benefits in the next year. Prior to the Spin-Off, income taxes as presented are calculated on a separate tax return basis modified to apply the benefits-for-loss approach and may not be reflective of the results that would have occurred if tax returns were filed on a stand-alone basis. In applying the benefits-for-loss methodology, the tax provision was computed as if the Business filed tax returns on a separate tax return basis independent of other Honeywell businesses with an adjustment to reflect a tax benefit for losses generated by the Business but utilized by other Honeywell businesses in a combined tax filing. Given that the taxpaying entities in which the Business operates were retained by Honeywell subsequent to the Spin-Off transaction, all tax payables and attributes, such as tax credit and tax loss carryforwards, associated with these entities was also retained by Honeywell whether or not such attribute was generated in whole or in part by the Business. As a result, the taxes payable and attributes that relate to the Business’s operations were recorded and settled through intercompany accounts with Honeywell since they are attributable to the taxable entity to be retained by Honeywell. Accordingly, a tax attribute, such a tax loss, generated by the Business but utilized by Honeywell, reduced the intercompany payable to Honeywell and be recorded as a current tax benefit in the calculation of the tax provision. We believe applying the separate tax return method modified to apply the benefits-for-loss approach was more appropriate than carrying the tax attribute forward since the attribute no longer exists, nor was the attribute included in the assets and liabilities of the Business subsequent to the Spin-Off transaction. Furthermore, the amount of the attributes that were generated by the Business but utilized by Honeywell were not material to the overall financial statements. Earnings Per Share Use of Estimates – Recent Accounting Pronouncements – In January 2017, the Financial Accounting Standards Board (“FASB”) issued amended guidance that simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under ASC 350. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The amendments eliminate the requirement to calculate a goodwill impairment charge by comparing the implied fair value of goodwill with its carrying amount (i.e., Step 2 of today’s goodwill impairment test). The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In August 2016, the FASB issued amended guidance clarifying how entities should classify certain cash receipts and cash payments on the statement of cash flows. The amended guidance addresses eight specific cash flow issues, including debt prepayment or extinguishment costs, and clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The amended guidance will be effective for interim and annual periods beginning after December 15, 2017; entities will be required to apply the guidance retrospectively and provide the relevant disclosures in ASC 250, in the first interim and annual periods in which they adopt the guidance. If it is impracticable to apply the amendments retrospectively for an issue, the amendments related to that issue would be applied prospectively. Early adoption is permitted. An entity that elects early adoption must adopt all of the amendments in the same period. Early adoption in an interim period is permitted, but any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In March 2016, the FASB issued amended guidance related to employee share-based payment accounting. The guidance requires all income tax effects of awards to be recognized in the income statement on a prospective basis. The guidance also requires presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity, and can be applied retrospectively or prospectively. The guidance increases the amount companies can withhold to cover income taxes on awards without triggering liability classification for shares used to satisfy statutory income tax withholding obligations and requires application of a modified retrospective transition method. The amended guidance will be effective for interim and annual periods beginning after December 15, 2016; early adoption is permitted if all provisions are adopted in the same period. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In February 2016, the FASB issued a new standard on accounting for leases which requires lessees to recognize most leases on their balance sheets related to the rights and obligations created by those leases. The new standard also requires disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases and will be effective for interim and annual periods beginning after December 15, 2018 (early adoption is permitted). The new standard should be applied under a modified retrospective approach. We are evaluating the impact of the new standard on our Consolidated and Combined Financial Statements and related disclosures. In November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes by permitting classification of all deferred tax assets and liabilities as noncurrent on the Consolidated and Combined Balance Sheets. The new guidance is effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those years (i.e., in the first quarter of 2017 for calendar year-end companies). Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The Business elected to early adopt the guidance on a prospective basis effective with the Consolidated and Combined Balance Sheets as of December 31, 2015. This is a change from the Business’s historical presentation whereby certain deferred tax assets and liabilities were classified as current and the remainder were classified as non-current. Adoption of the guidance resulted in a reclassification of $8,470 from current assets to noncurrent assets within the Consolidated and Combined Balance Sheets as of December 31, 2015. In May 2014 and in subsequent related updates and amendments, the FASB issued guidance on revenue from contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The effective date was deferred for one year to the interim and annual periods beginning on or after December 15, 2017. Early adoption is permitted as of the original effective date – interim and annual periods beginning on or after December 15, 2016. The guidance permits the use of either a retrospective or cumulative effect transition method. We have not made a decision on the method of adoption. The analysis identifying areas that will be impacted by the new guidance and their potential impacts to the consolidated financial statements and related disclosures is currently underway. While data is still being accumulated, our initial indication is that revenue from Nylon 6 and our other products sold as part of the Nylon 6 manufacturing process are expected to remain substantially unchanged from our current revenue recognition model. A final determination cannot be made until we complete our analysis.

Related Party Transactions [Abstract]
Related Party Transactions Disclosure [Text Block]	Note 3. Related Party Transactions with Honeywell The Consolidated and Combined Financial Statements have been prepared on a stand-alone basis and are derived from the Consolidated and Combined Financial Statements and accounting records of Honeywell. Prior to consummation of the Spin-Off, Honeywell provided certain services, such as legal, accounting, information technology, human resources and other infrastructure support, on behalf of the Business. The cost of these services were allocated to the Business on a direct usage basis when identifiable, with the remainder allocated on the basis of revenues, headcount or other relevant measures. When not specifically identifiable, legal and accounting costs were allocated on the basis of revenues, information technology and human resources were allocated on the basis of headcount and other infrastructure support was allocated on the basis of revenue. During the nine months ended September 30, 2016 and the years ended December 31, 2015 and 2014, AdvanSix was allocated $31,877, $49,292 and $57,171, respectively, of general corporate expenses incurred by Honeywell for certain services, such as legal, accounting, information technology, human resources, other infrastructure support and shared facilities, on behalf of the Business. These expenses have been reflected within Costs of goods sold and Selling, general and administrative expenses in the Consolidated and Combined Statements of Operations. Sales to Honeywell during the nine months ended September 30, 2016 and the years ended December 31, 2015 and 2014 were $5,955, $9,071 and $8,585, respectively. Of these sales, during the nine months ended September 30, 2016 and the years ended December 31, 2015 and 2014, $5,682, $7,736 and $8,362, respectively, were sold to Honeywell at zero margin. Costs of goods sold to Honeywell during the nine months ended September 30, 2016 and the years ended December 31, 2015 and 2014 were $5,842, $288 and $378, respectively. Purchases from Honeywell during the nine months ended September 30, 2016 and the years ended December 31, 2015 and 2014 were $3,299, $4,694 and $5,140, respectively. The total net effect of the settlement of these intercompany transactions, prior to the Spin-off, is reflected in the Consolidated and Combined Statements of Cash Flows as a financing activity and in the Consolidated and Combined Balance Sheets as Invested equity. While we were owned by Honeywell, a centralized approach to cash management and financing of operations was used.

For 2016, 2015 and 2014, there were no unrecognized tax benefits recorded by the Company. Although there are no unrecognized income tax benefits, when applicable, the Company’s policy is to report interest expense related to unrecognized income tax benefits in the income tax provision. Deferred tax assets (liabilities) The tax effects of temporary differences which give rise to future income tax benefits and expenses are as follows: December 31, 2016 2015 Deferred tax assets: Net Operating Loss $ 12,560 $ – Accruals and Reserves 6,772 5,673 Inventory 215 4,520 Pension Obligation 13,086 – Other 141 184 Total gross deferred tax assets 32,774 10,377 Less: Valuation Allowance – – Total deferred tax assets $ 32,774 $ 10,377 Deferred tax liabilities: Property, plant & equipment $ (145,712 ) $ (123,574 ) Intangibles (1,262 ) (1,713 ) Total deferred tax liabilities (146,974 ) (125,287 ) Net deferred taxes $ (114,200 ) $ (114,910 ) The net deferred taxes are primarily related to U.S. operations. As of December 31, 2016, we recognized a federal net operating loss (“NOL”) carryforward of $32,392, which is expected to expire in 2036, and a foreign NOL carryforward of $213 which is not subject to expiration. We also have state NOL carryforwards in multiple jurisdictions, including most materially in Virginia, $14,248. The most significant state NOL carryforwards are expected to expire in 2036. There were no material tax loss or tax credit carryforwards at December 31, 2015. We believe that the federal, foreign and state NOL carryforwards and other deferred tax assets are more likely than not to be realized and we have not recorded a valuation allowance against the deferred tax assets. As of December 31, 2016, there are no undistributed earnings of the Business’ non-U.S. subsidiary and, as such, we have not provided a deferred tax liability for undistributed earnings.

Disclosure Text Block [Abstract]
Long-term Debt [Text Block]	Note 9. Long-term Debt and Credit Agreement The Company’s debt at December 31, 2016 consisted of the following: Total term loan outstanding $ 264,838 Amounts outstanding under the Revolving Credit Facility – Total outstanding indebtedness 264,838 Less: amounts due within one year – Total long term debt due after one year $ 264,838 At December 31, 2016, the Company assessed the amount recorded under the Term Loan (defined below) and the Revolving Credit Facility (defined below) and determined that such amounts approximated fair value. The fair values of the debt are based on quoted inactive market prices and are therefore classified as Level 2 within the valuation hierarchy. The Term Loan is presented net of deferred costs of issuance, which are amortized using the effective interest method over the term of the Term Loan. Gross deferred issuance costs at the inception of the Term Loan were $1,881 and, as of December 31, 2016, there were $1,787 of unamortized deferred issuance costs netted against the Term-Loan. Scheduled principal repayments under the Term Loan subsequent to December 31, 2016 are as follows: 2017 $ – 2018 16,875 2019 27,000 2020 27,000 Thereafter 195,750 Total $ 266,625 Credit Agreement On September 30, 2016, in connection with the consummation of the Spin-Off, the Company as the borrower, entered into a Credit Agreement with Bank of America, as administrative agent (the “Credit Agreement”). The Credit Agreement consists of a $270.0 million term loan (the “Term Loan”) and a $155.0 million revolving loan facility (the “Revolving Credit Facility”). The Revolving Credit Facility includes a $25.0 million letter-of-credit sub-facility and a $20.0 million Swing-Line Loan sub-facility, issuances against which reduce the available capacity for borrowing. As of December 31, 2016, the Company has issued $2.1 million of letters of credit, against which no funds have been drawn, and has no outstanding borrowings against the Swing-Line Loan. The unutilized portion of the Revolving Credit Facility is subject to an annual commitment fee of 0.25% to 0.40% depending on the Company’s consolidated leverage ratio. The Term Loan and the Revolving Credit Facility both have a scheduled maturity date of September 30, 2021. The interest rates on borrowings under the facilities are based on, at the option of the Company, either: (a) the London Interbank Offered Rate (“LIBOR”), plus a margin of 2.25% to 3.00% depending on the Company’s consolidated leverage ratio, or (b) the higher of (i) the Federal Funds Rate plus 0.5%, (ii) Bank of America’s “prime rate”, and (iii) LIBOR plus 1.0%, plus a margin of 1.25% to 2.00% depending on the Company’s consolidated leverage ratio. The proceeds of the Term Loan, net of adjustments for certain working capital and other items, were used to fund a cash distribution to Honeywell in connection with the Spin-Off. Amounts available under the Revolving Credit Facility may be used for working capital, general corporate purposes, and other uses, all as more fully set forth in the Credit Agreement. The Company incurred approximately $1.9 million in debt issuance costs related to the Term Loan and $1.0 million in costs related to the Revolving Credit Facility. The debt issuance costs associated with the Term Loan were recorded as a reduction of the principal balance of the debt, and the Revolving Credit Facility costs were capitalized in Other assets. All issuance costs are being amortized through interest expense for the duration of each respective debt facility. The accretion in interest expense during the year ended December 31, 2016 was $148. The obligations under the Credit Agreement are secured by liens on substantially all of the assets of AdvanSix Inc. The Credit Agreement contains customary covenants limiting the ability of the Company and its subsidiaries to, among other things, pay cash dividends, incur debt or liens, redeem or repurchase stock of the Company, enter into transactions with affiliates, make investments, make capital expenditures, merge or consolidate with others or dispose of assets. The Credit Agreement also contains financial covenants that require the Company to maintain a Consolidated Interest Coverage Ratio (as defined in the Credit Agreement) of not less than 3:00 to 1:00 and to maintain a Consolidated Leverage Ratio of (i) 3:00 to 1:00 or less for the fiscal quarter ending September 30, 2016, through and including the fiscal quarter ending March 31, 2018, (ii) 2:75 to 1:00 or less for the fiscal quarter ending June 30, 2018, through and including the fiscal quarter ending March 31, 2019, and (iii) 2:50 to 1:00 or less for the fiscal quarter ending June 30, 2019, and each fiscal quarter thereafter (subject to the Company’s option to elect a consolidated leverage ratio increase in connection with certain acquisitions). If the Company does not comply with the covenants in the Credit Agreement, the lenders may, subject to customary cure rights, require the immediate payment of all amounts outstanding under the Credit Agreement.

Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Note 10. Postretirement Benefit Obligations Prior to the Spin-Off certain of our employees participated in a defined benefit pension plan (the “Shared Plan”) sponsored by Honeywell which includes participants of other Honeywell subsidiaries and operations. We accounted for our participation in the Shared Plan as a multiemployer benefit plan. Accordingly, we did not record an asset or liability to recognize the funded status of the Shared Plan. The related pension expense was allocated based on annual service cost of active participants and reported within Costs of goods sold and Selling, general and administrative expenses in the Combined Statements of Operations. The pension expense related to our participation in the Shared Plan for the nine months ended September 30, 2016 and years ended December 31, 2015, 2014 was $5,151, $10,215 and $9,249, respectively. As of the date of separation from Honeywell, these employees’ entitlement to benefits in Honeywell’s plans was frozen and they will accrue no further benefits in Honeywell’s plans. Honeywell retained the liability for benefits payable to eligible employees, which are based on age, years of service and average pay upon retirement. Upon consummation of the Spin-Off, AdvanSix employees who were participants in a Honeywell defined benefit pension plan became participants in the AdvanSix defined benefit pension plan (“AdvanSix Retirement Earnings Plan”). The AdvanSix Retirement Earnings Plan has the same benefit formula as the Honeywell defined benefit pension plan. Moreover, vesting service, benefit accrual service and compensation credited under the Honeywell defined benefit pension plan apply to the determination of pension benefits under the AdvanSix Retirement Earnings Plan. Benefits earned under the AdvanSix Retirement Earnings Plan shall be reduced by the value of benefits accrued under the Honeywell plans. The following tables summarize the balance sheet impact, including the benefit obligations, assets and funded status associated with the AdvanSix Retirement Earnings Plan. Change in benefit obligation: Benefit obligation at October 1, 2016 (Spin-Off) $ 34,935 Service Cost 1,796 Interest Cost 315 Actuarial (gains) losses (3,159 ) Benefit obligation at December 31, 2016 $ 33,887 Change in plan assets: Fair value of plan assets at October 1, 2016 (Spin-Off) $ – Company contributions – Fair value of plan assets at end of year – Funded status of plans $ (33,887 ) Amounts recognized in Balance Sheet consists of: Accrued pension liabilities-current (1) $ (343 ) Accrued pension liabilities-noncurrent (2) (33,544 ) Net amount recognized $ (33,887 ) (1) Included in accrued liabilities on Balance Sheet (2) Included in postretirement benefit obligations on Balance Sheet Amounts recognized in accumulated other comprehensive income (loss) associated with our pension plan at December 31, 2016 are as follows: Transition obligation $ – Prior service (credit) cost – Net actuarial gain (3,159 ) Net amount recognized $ (3,159 ) The components of net periodic benefit cost and other amounts recognized in other comprehensive income for our pension plan include the following components: Years ended December 31, 2016 2015 2014 Service cost $ 1,796 $ – $ – Interest cost 315 – – Expected return on plan assets – – – Recognition of actuarial losses – – – Net periodic benefit cost $ 2,111 $ – $ – Other Changes in Benefits Obligations Recognized in Other Comprehensive Income (loss) Actuarial gains (3,159 ) – – Total recognized in other comprehensive income $ (3,159 ) $ – $ – Total recognized in net periodic benefit cost and other comprehensive income $ (1,048 ) $ – $ – The estimated actuarial gain that will be amortized from accumulated other comprehensive income (loss) into net periodic benefit cost in 2017 is expected to be nil. Significant actuarial assumptions used in determining the benefit obligations and net periodic benefit cost for our pension plan were as follows: 2016 Actuarial assumptions used to determine benefit obligations as of December 31,: Discount rate 4.48% Expected annual rate of compensation increase 2.75% Actuarial assumptions used to determine the net periodic benefit cost for the year ended December 31,: Discount rate 3.93% Expected annual rate of compensation increase 3.75% The discount rate for our pension plan reflects the current rate at which the associated liabilities could be settled at the measurement date of December 31, 2016. To determine discount rates for our pension plan, we use a modeling process that involves matching the expected cash outflows of our benefit plan to a yield curve constructed from a portfolio of high quality, fixed-income debt instruments. We use the single weighted-average yield of this hypothetical portfolio as a discount rate benchmark. The accumulated benefit obligation for our pension plan was $31.2 million as of December 31, 2016. No assets had been contributed to the Plan prior to December 31, 2016. Our general funding policy for our pension plan is to contribute amounts at least sufficient to satisfy regulatory funding standards. We plan to make estimated payments through such time as the plan is fully funded. During January 2017, the Company made a contribution to the AdvanSix Retirement Earnings Plan of $2.2 million. The Company plans to make additional contributions of approximately $20 million during 2017 sufficient to satisfy pension funding requirements as well as additional contributions in future years sufficient to satisfy pension funding requirements in those periods. Benefit payments, including amounts to be paid from Company assets, and reflecting expected future service, as appropriate, are expected to be paid during the following years: 2017 $ 343 2018 879 2019 1,481 2020 2,106 2021 2,778 2022–2026 24,379

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Note 12. Commitments and Contingencies Litigation: The Company is subject to a number of lawsuits, investigations and disputes (some of which involve substantial amounts claimed) arising out of the conduct of the Company or other third parties in the normal and ordinary course of business, including matters relating to commercial transactions. A liability is recognized for any contingency that is probable of occurrence and reasonably estimable. The Company continually assesses the likelihood of adverse judgments or outcomes in these matters, as well as potential ranges of possible losses (taking into consideration any insurance recoveries), based on an analysis of each matter with the assistance of legal counsel and, if applicable, other experts. Given the uncertainty inherent in such lawsuits, investigations and disputes, the Company does not believe it is possible to develop estimates of reasonably possible loss in excess of current accruals for these matters. Considering the Company’s past experience and existing accruals, the Business does not expect the outcome of these matters, either individually or in the aggregate, to have a material adverse effect on the Company’s Consolidated and Combined Balance Sheets, results of operations or cash flows. Potential liabilities are subject to change due to new developments, changes in settlement strategy or the impact of evidentiary requirements, which could cause the Company to pay damage awards or settlements (or become subject to equitable remedies) that could have a material adverse effect on the Company’s consolidated and combined results of operations, balance sheet and/or operating cash flows in the periods recognized or paid. Unconditional Purchase Obligations: In the normal course of business, the Company makes commitments to purchase goods with various vendors in the normal course of business which are consistent with our expected requirements and primarily relate to cumene, oleum, sulfur and natural gas as well as a long term agreement for loading, unloading and the handling of a portion of our ammonium sulfate export volumes. Future minimum payments for these unconditional purchase obligations as of December 31, 2016 are as follows (dollars in thousands): Year Amount 2017 $ 67,154 2018 26,854 2019 26,957 2020 27,006 2021 26,920 Thereafter 12,649 $ 187,540

Basic and Diluted EPS for all periods prior to the Spin-off reflect the number of distributed shares, or 30,482,966 shares. For the 2016 year to date calculations, these shares are treated as issued and outstanding from January 1, 2016 for purposes of calculating historical basic earnings per share.

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 15. Stock-Based Compensation Plans On September 8, 2016, our Board adopted, and Honeywell, as our sole stockholder, approved, the 2016 Stock Incentive Plan of AdvanSix Inc. and its Affiliates (the “Equity Plan”). The Equity Plan provides for the grant of stock options, stock appreciation rights, performance awards, restricted stock units, restricted stock, other stock-based awards, and non-share-based awards. The maximum aggregate number of shares of our common stock that may be issued under all stock-based awards granted under the Equity Plan is 3,350,000. Of those shares, only 1,750,000 may be subject, on a one-for-one basis, to awards granted under the Equity Plan that are not stock options or stock appreciation rights (“full-value awards”). After the number of shares subject to full-value awards exceed such limit, each share subject to future full-value awards would reduce the number of shares available for grant under the Equity Plan by four shares, with the exception of awards to non-employee directors, which shall not count towards such limit and shares related to such awards shall always be counted on a one-for-one basis. Under the terms of the Equity Plan, there were 2,441,460 shares of AdvanSix common stock available for future grants of full value awards, of which 841,460 were available for awards other than full-value awards on a one-for-one basis, at December 31, 2016.

Income Tax, Policy [Policy Text Block]	Income Taxes During the 4 th The benefit of tax positions taken or expected to be taken in our income tax returns are recognized in the financial statements if such positions are more likely than not of being sustained upon examination by taxing authorities. Differences between tax positions taken or expected to be taken in a tax return and the benefit recognized and measured pursuant to the interpretation are referred to as “unrecognized benefits”. A liability is recognized (or amount of net operating loss carryover or amount of tax refundable is reduced) for an unrecognized tax benefit because it represents an enterprise’s potential future obligation to the taxing authority for a tax position that was not recognized as a result of applying the provisions of ASC 740. Interest costs and related penalties related to unrecognized tax benefits are required to be calculated, if applicable. Our policy is to classify tax related interest and penalties, if any, as a component of income tax expense. No interest or penalties were recorded during the years ended December 31, 2016 and 2015. As of December 31, 2016 and December 31, 2015, no liability for unrecognized tax benefits was required to be reported. We do not expect any significant changes in our unrecognized tax benefits in the next year. Prior to the Spin-Off, income taxes as presented are calculated on a separate tax return basis modified to apply the benefits-for-loss approach and may not be reflective of the results that would have occurred if tax returns were filed on a stand-alone basis. In applying the benefits-for-loss methodology, the tax provision was computed as if the Business filed tax returns on a separate tax return basis independent of other Honeywell businesses with an adjustment to reflect a tax benefit for losses generated by the Business but utilized by other Honeywell businesses in a combined tax filing. Given that the taxpaying entities in which the Business operates were retained by Honeywell subsequent to the Spin-Off transaction, all tax payables and attributes, such as tax credit and tax loss carryforwards, associated with these entities was also retained by Honeywell whether or not such attribute was generated in whole or in part by the Business. As a result, the taxes payable and attributes that relate to the Business’s operations were recorded and settled through intercompany accounts with Honeywell since they are attributable to the taxable entity to be retained by Honeywell. Accordingly, a tax attribute, such a tax loss, generated by the Business but utilized by Honeywell, reduced the intercompany payable to Honeywell and be recorded as a current tax benefit in the calculation of the tax provision. We believe applying the separate tax return method modified to apply the benefits-for-loss approach was more appropriate than carrying the tax attribute forward since the attribute no longer exists, nor was the attribute included in the assets and liabilities of the Business subsequent to the Spin-Off transaction. Furthermore, the amount of the attributes that were generated by the Business but utilized by Honeywell were not material to the overall financial statements.

New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements – In January 2017, the Financial Accounting Standards Board (“FASB”) issued amended guidance that simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under ASC 350. Under the new guidance, if a reporting unit’s carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The amendments eliminate the requirement to calculate a goodwill impairment charge by comparing the implied fair value of goodwill with its carrying amount (i.e., Step 2 of today’s goodwill impairment test). The standard will be applied prospectively and is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In August 2016, the FASB issued amended guidance clarifying how entities should classify certain cash receipts and cash payments on the statement of cash flows. The amended guidance addresses eight specific cash flow issues, including debt prepayment or extinguishment costs, and clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The amended guidance will be effective for interim and annual periods beginning after December 15, 2017; entities will be required to apply the guidance retrospectively and provide the relevant disclosures in ASC 250, in the first interim and annual periods in which they adopt the guidance. If it is impracticable to apply the amendments retrospectively for an issue, the amendments related to that issue would be applied prospectively. Early adoption is permitted. An entity that elects early adoption must adopt all of the amendments in the same period. Early adoption in an interim period is permitted, but any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In March 2016, the FASB issued amended guidance related to employee share-based payment accounting. The guidance requires all income tax effects of awards to be recognized in the income statement on a prospective basis. The guidance also requires presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity, and can be applied retrospectively or prospectively. The guidance increases the amount companies can withhold to cover income taxes on awards without triggering liability classification for shares used to satisfy statutory income tax withholding obligations and requires application of a modified retrospective transition method. The amended guidance will be effective for interim and annual periods beginning after December 15, 2016; early adoption is permitted if all provisions are adopted in the same period. We are evaluating the impact of the amended guidance on our Consolidated and Combined Financial Statements and related disclosures. In February 2016, the FASB issued a new standard on accounting for leases which requires lessees to recognize most leases on their balance sheets related to the rights and obligations created by those leases. The new standard also requires disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases and will be effective for interim and annual periods beginning after December 15, 2018 (early adoption is permitted). The new standard should be applied under a modified retrospective approach. We are evaluating the impact of the new standard on our Consolidated and Combined Financial Statements and related disclosures. In November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes by permitting classification of all deferred tax assets and liabilities as noncurrent on the Consolidated and Combined Balance Sheets. The new guidance is effective for public business entities in fiscal years beginning after December 15, 2016, including interim periods within those years (i.e., in the first quarter of 2017 for calendar year-end companies). Early adoption is permitted for all entities as of the beginning of an interim or annual reporting period. The Business elected to early adopt the guidance on a prospective basis effective with the Consolidated and Combined Balance Sheets as of December 31, 2015. This is a change from the Business’s historical presentation whereby certain deferred tax assets and liabilities were classified as current and the remainder were classified as non-current. Adoption of the guidance resulted in a reclassification of $8,470 from current assets to noncurrent assets within the Consolidated and Combined Balance Sheets as of December 31, 2015. In May 2014 and in subsequent related updates and amendments, the FASB issued guidance on revenue from contracts with customers that will supersede most current revenue recognition guidance, including industry-specific guidance. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. Other major provisions include capitalization of certain contract costs, consideration of time value of money in the transaction price, and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. The effective date was deferred for one year to the interim and annual periods beginning on or after December 15, 2017. Early adoption is permitted as of the original effective date – interim and annual periods beginning on or after December 15, 2016. The guidance permits the use of either a retrospective or cumulative effect transition method. We have not made a decision on the method of adoption. The analysis identifying areas that will be impacted by the new guidance and their potential impacts to the consolidated financial statements and related disclosures is currently underway. While data is still being accumulated, our initial indication is that revenue from Nylon 6 and our other products sold as part of the Nylon 6 manufacturing process are expected to remain substantially unchanged from our current revenue recognition model. A final determination cannot be made until we complete our analysis.

Stock-Based Compensation Plans (Details) [Line Items]
Employee Stock Ownership Plan (ESOP), Plan Description	On September 8, 2016, our Board adopted,and Honeywell, as our sole stockholder, approved, the 2016 Stock Incentive Plan of AdvanSix Inc. and its Affiliates (the “EquityPlan”). The Equity Plan provides for the grant of stock options, stock appreciation rights, performance awards, restrictedstock units, restricted stock, other stock-based awards, and non-share-based awards. The maximum aggregate number of shares ofour common stock that may be issued under all stock-based awards granted under the Equity Plan is 3,350,000. Of those shares, only1,750,000 may be subject, on a one-for-one basis, to awards granted under the Equity Plan that are not stock options or stock appreciationrights (“full-value awards”). After the number of shares subject to full-value awards exceed such limit, each sharesubject to future full-value awards would reduce the number of shares available for grant under the Equity Plan by four shares,with the exception of awards to non-employee directors, which shall not count towards such limit and shares related to such awardsshall always be counted on a one-for-one basis.
