Disclosure Text Block [Abstract]
Nature of Operations [Text Block]	1) Nature of operations and basis of presentation Viceroy Acquisition Corporation Viceroy Acquisition Corporation (“Viceroy”) was incorporated under the laws of the state of Delaware on August 12, 2005 to serve as a vehicle for the acquisition of one or more operating businesses in the oil and gas industry. On July 12, 2006, Viceroy completed an equity offering (see Note 16). On October 31, 2006, Viceroy acquired all of the issued and outstanding shares of Eastman SE, Inc. (“Eastman SE”) from Eastman Chemical Company (“Eastman Chemical”). Immediately subsequent to the acquisition, Viceroy changed its name to FutureFuel Corp. (“FutureFuel”) and Eastman SE changed its name to FutureFuel Chemical Company (“FutureFuel Chemical”). Eastman SE, Inc. Eastman SE was incorporated under the laws of the state of Delaware on September 1, 2005 and subsequent thereto operated as a wholly owned subsidiary of Eastman Chemical through October 31, 2006. Eastman SE was incorporated for purposes of effecting a sale of Eastman Chemical’s manufacturing facility in Batesville, Arkansas (the “Batesville Plant”). The Batesville Plant was constructed to produce proprietary photographic chemicals for Eastman Kodak Company (“Eastman Kodak”). Over the years, Eastman Kodak shifted the plant’s focus away from the photographic imaging business to the custom synthesis of fine chemicals and organic chemical intermediates used in a variety of end markets, including paints and coatings, plastics and polymers, pharmaceuticals, food supplements, household detergents, and agricultural products. In 2005, the Batesville Plant began the implementation of a bio-based products platform. This included the production of biofuels (biodiesel) and bio-based specialty chemical products (bio-based solvents, chemicals, and intermediates). In addition to bio-based products, the Batesville Plant continues to manufacture fine chemicals and other organic chemicals.

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	2) Significant accounting policies Consolidation The accompanying consolidated financial statements include the accounts of FutureFuel and its wholly-owned subsidiaries: FutureFuel Chemical Company; FFC Grain, L.L.C., which was formed in 2009 to acquire a granary in Marianna, Arkansas; FutureFuel Warehouse Company, L.L.C., which was formed in 2011 to acquire a warehouse in Batesville, Arkansas; and Legacy Regional Transport, L.L.C., which was formed in 2012 and operates FutureFuel’s truck fleet. All significant intercompany transactions have been eliminated. Cash and cash equivalents Cash equivalents consist of highly liquid investments with maturities of three months or less when purchased and are carried at cost, which approximates market. FutureFuel places its temporary cash investments with high credit quality financial institutions. At times, bank deposits may be in excess of the Federal Deposit Insurance Corporation insurance limit. Accounts receivable, allowance for doubtful accounts and credit risk Accounts receivable are recorded at the invoiced amount and do not bear interest. FutureFuel has established procedures to monitor credit risk and has not experienced significant credit losses in prior years. Accounts receivable have been reduced by an allowance for amounts that may be uncollectible in the future. This estimated allowance is based upon management’s evaluation of the collectability of individual invoices and is based upon management’s evaluation of the financial condition of its customers and historical bad debt experience. Write-offs are recorded at the time a customer receivable is deemed uncollectible. Customer concentrations Significant portions of FutureFuel’s sales are made to a relatively small number of customers. All sales of a laundry detergent additive are made to a leading North American consumer products company. Sales of the laundry detergent additive were less than 10% of total revenue for the year ended December 31, 2015 and greater than 10% for the years ended December 31, 2014 and 2013, or $43,927 and $56,596, respectively. Sales to one biodiesel customer totaled $33,255, $62,994, and $135,273 for the years ended December 31, 2015, 2014, and 2013, respectively. Additionally, sales of biodiesel, petrodiesel, petrodiesel blends, and other petroleum products to a related party totaled $64,981, $39,090, and $9,420 for the years ended December 31, 2015, 2014, and 2013, respectively. See Note 19 below. Inventory FutureFuel determines the cost of substantially all raw materials and finished goods inventories by the last-in, first-out (“LIFO”) method. FutureFuel writes down its inventories for estimated obsolescence or unmarketable inventory equal to the difference between the carrying value of inventory and the estimated market value based upon current demand and market conditions. Financial and derivative instruments The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses and other current liabilities approximate their fair values due to the short-term maturities of these instruments. FutureFuel records all derivative instruments at fair value. Fair value is determined by using the closing prices of the derivative instruments on the New York Mercantile Exchange at the end of an accounting period. Changes in fair value of the derivative instruments are recorded in the statements of operations as a component of cost of goods sold. FutureFuel maintains a margin account with a broker to collateralize these derivative instruments. In order to manage commodity price risk caused by market fluctuations in biofuel prices, future purchases of feedstock used in our biodiesel production, physical feedstock, finished product inventories attributed to the process, and other petroleum products purchased or sold, we may enter into exchange traded commodity futures and options contracts. We account for these derivative instruments in accordance with ASC 815-20-25, Derivatives and Hedging, Hedging-General, Recognition. Under this standard, the accounting for changes in the fair value of a derivative instrument depends upon whether it has been designated as an accounting hedging relationship and, further, on the type of hedging relationship. To qualify for designation as an accounting hedging relationship, specific criteria must be met and appropriate documentation maintained. We had no derivative instruments that qualified under these rules as designated accounting hedges in 2015 or 2014. Changes in the fair value of our derivative instruments are recognized at the end of each accounting period and recorded in the statement of operations as a component of cost of goods sold. Our immediate recognition of derivative instrument gains and losses can cause net income to be volatile from period to period due to the timing of the change in value of the derivative instruments relative to the sale of the physical commodity sold. As of December 31, 2015 and 2014, the fair values of our derivative instruments were a net asset in the amount of $3,362 and $68, respectively. They were comprised of short positions of 200 regulated options with a fair value of $(427) and a short position of 631 regulated fixed price futures contracts with a fair value of $3,789 at December 31, 2015. Comparatively, we held a short position of 350 regulated options with a value of $(794) and a short position of 225 regulated fixed price future commitments with a value of $862 at December 31, 2014. Property, plant and equipment Property, plant, and equipment is carried at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When FutureFuel retires or otherwise disposes of an asset, it removes the cost of such asset and related accumulated depreciation from the accounts. FutureFuel records any profit and loss on retirement or other disposition in earnings. Depreciation is provided using the straight-line method over the following estimated useful lives: Building & building equipment (years) 20 - 39 Machinery and equipment (years) 3 – 33 Transportation equipment (years) 5 – 33 Other (years) 5 – 33 Impairment of assets Long-lived tangible assets FutureFuel evaluates the carrying value of long-lived tangible assets when events or changes in circumstances indicate that the carrying value may not be recoverable. Such events and circumstances include, but are not limited to, significant decreases in the market value of the asset, adverse changes in the extent or manner in which the asset is being used, significant changes in business climate, or current or projected cash flow losses associated with the use of the assets. The carrying value of a long-lived asset is considered impaired when the total projected undiscounted cash flows from such assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. For long-lived assets to be held for use in future operations and for fixed (tangible) assets, fair value is determined primarily using either the projected cash flows discounted at a rate commensurate with the risk involved or an appraisal. For long-lived assets to be disposed of by sale or other than sale, fair value is determined in a similar manner, except that fair values are reduced for disposal costs. Indefinite-lived in tangible asset Intangible assets with indefinite lives are not amortized, but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. The Company performs annual impairment tests of the intangible assets during the fourth quarter of each fiscal year and assesses qualitative factors to determine the likelihood of impairment. The Company’s qualitative analysis includes, but is not limited to, assessing the changes in macroeconomic conditions, legal and regulatory environment, industry and market conditions, financial performance, and any other relevant events or circumstances specific to the intangible asset. If it is more likely than not that the fair value of the intangible asset is greater than the carrying value, no further testing is required. Otherwise, the Company will apply the quantitative impairment test method. In performing the Company's qualitative analysis, the Company determined that it was more likely than not that the indefinite-lived intangible asset's fair value was greater than the carrying value. Deferred revenue FutureFuel has signed contracts with customers to construct plant and related assets on FutureFuel’s property for the manufacture of custom chemicals. The cost of construction has been funded by the customers with title and risk of loss to the equipment residing with FutureFuel. Reimbursements are recognized as deferred revenue and are amortized over the expected life of the customer relationship starting upon the completion of construction and the asset being placed into service. Additionally, FutureFuel has been awarded grants from governmental agencies related to the construction of production equipment and infrastructural improvements at its plant site. The cost of construction of these projects has been either funded by the governmental agencies directly or funded by FutureFuel who has then been reimbursed by the governmental agencies. Direct payments and reimbursements for construction costs have been recognized as deferred revenue and will be amortized into earnings over the expected life of the applicable customer relationship or the life of the asset if no direct customer relationship is tied to the asset. Such amortization will not begin until the asset has been placed into service and all contingencies associated with the grants are fulfilled. Asset retirement obligations FutureFuel establishes reserves for closure/post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units such as destructors, landfills, storage tanks, and boilers. When these types of assets are constructed or installed, a liability is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets, the applicable regulatory closure requirements, and FutureFuel’s environmental policies and practices. These expenses are charged into earnings over the estimated useful life of the assets. Currently, FutureFuel estimates the useful life of each individual asset up to 35 years. Changes made in estimates of the asset retirement obligation costs or the estimate of the useful lives of these assets are reflected in earnings as an increase or decrease in the period such changes are made. Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense. Income taxes Income taxes are accounted for using the asset and liability method. Under this method, income tax assets and liabilities are recognized for temporary differences between financial statement carrying amounts of assets and liabilities and their respective income tax basis. A future income tax asset or liability is estimated for each temporary difference using enacted and substantively enacted income tax rates and laws expected to be in effect when the asset is realized or the liability settled. A valuation allowance is established, if necessary, to reduce any future income tax asset to an amount that is more likely than not to be realized. FASB ASC Topic 740, Income Taxes Revenue recognition For most product sales, revenue is recognized when product is shipped from our facilities and risk of loss and title have passed to the customer, which is in accordance with our customer contracts and the stated shipping terms. All custom manufactured products are manufactured under written contracts. Performance chemicals and biofuels are usually sold pursuant to the terms of written purchase orders. In general, customers do not have any rights of return, except for quality disputes. However, all of our products are tested for quality before shipment, and historically returns have been inconsequential. FutureFuel does not offer rebates or other warranties. Bill and hold transactions for 2015, 2014, and 2013 related to three specialty chemical customers in 2015, four in 2014, and six in 2013, whereby revenue was recognized in accordance with contractual agreements based on product produced and ready for use. These sales were subject to written monthly purchase orders with agreement that production was reasonable. The inventory was custom manufactured and stored at the customer’s request and could not be sold to another buyer. Credit and payment terms for bill and hold transactions are similar to other specialty chemical customers. Sales revenue under bill and hold arrangements totaled $28,740, $31,598, and $44,047 for the years ended December 31, 2015, 2014, and 2013, respectively. Taxes collected from customers and remitted to governmental authorities Taxes collected from customers and remitted to governmental authorities are excluded from revenues and cost of goods sold. Shipping and handling fees Shipping and handling fees related to sales transactions are billed to customers and recorded as sales revenues. Cost of goods sold and selling, general, and administration expenses Cost of goods sold includes the costs of inventory sold, related purchasing, distribution, and warehousing costs, costs incurred for shipping and handling, and environmental remediation costs. In 2015, 2014 and 2013, the biodiesel tax incentive for blending biodiesel with petroleum diesel is netted with costs of goods sold. The one dollar per gallon blenders’ tax credit (“BTC”) amounted to one cent for each percentage point of vegetable oil or animal fat biodiesel that was blended with petrodiesel. The credit was recognized as it was earned, i.e., when biodiesel blended with petrodiesel was sold or when such credit was made law. This tax credit is set to expire on December 31, 2016. Selling, general, and administration expenses include personnel costs associated with sales, marketing and administration, legal and legal-related costs, consulting and professional services fees, advertising expenses, and other similar costs. Research and development All costs identified as research and development costs are charged to expense when incurred. Planned major maintenance activities Expenditures for planned major maintenance activities are recognized as expense as incurred. Earnings per share Earnings per share is computed using the two-class method in accordance with ASC 260, Earnings Per Share Contingently issuable shares associated with outstanding service-based restricted stock shares were not included in the earnings per share calculations for the year ended December 31, 2015 and 2014 as the vesting conditions had not been satisfied. No such restricted stock units existed in 2013. Comprehensive income Comprehensive income is comprised of net income and other comprehensive income/(losses) (“OCI”). Comprehensive income comprises all changes in stockholders’ equity from transactions and other events and circumstances from non-owner sources. FutureFuel’s OCI is comprised of unrealized gains and losses resulting from its investment in certain marketable securities classified as available for sale (see Note 6). For the year ended December 31, 2015, FutureFuel recorded other comprehensive losses of $2,204, net of income tax benefit of $1,546, on these securities. For the year ended December 31, 2014, FutureFuel recorded other comprehensive losses of $3,177, net of income tax benefit of $1,980, on these securities. For the year ended December 31, 2013, FutureFuel recorded other comprehensive income of $4,839, net of income taxes of $3,018, on these securities. For the year ended December 31, 2015 and 2013, FutureFuel reclassified a portion of its unrealized income related to certain of its available-for-sale securities from OCI to a component of net income as a result of recording an other than temporary impairment. This reclassification totaled $394 and $207, net of income tax benefit of $212 and $129 for the years ended December 31, 2015 and 2013, respectively. No such reclassification was made for the year ended December 31, 2014. Commitments and contingent liabilities In the ordinary course of its business, FutureFuel enters into supply and sales contracts as deemed commercially desirable. Supply contracts are utilized to ensure the availability of raw materials used in the production process. Sales contracts are utilized to ensure the future sale of produced product. FutureFuel and its operations from time to time may be parties to or targets of lawsuits, claims, investigations, and proceedings including product liability, personal injury, patent and intellectual property, commercial, contract, environmental, health and safety, and environmental matters, which are handled and defended in the ordinary course of business. FutureFuel accrues a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, FutureFuel accrues the minimum amount. Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during a reporting period. Estimates are used when accounting for allowance for doubtful accounts, depreciation, amortization, asset retirement obligations, and income taxes as well as the evaluation of potential losses due to impairments or future liabilities. Actual results could differ materially from those estimates. Segment reporting FutureFuel identifies operating segments when separate financial information is available that is evaluated regularly by its chief operating decision maker in assessing the performance of those segments and in determining how to allocate resources. FutureFuel has determined that it has two reportable segments organized along product lines -- chemicals and biofuels.

Other Income and Other Expense Disclosure [Text Block]	3) Reinstatement of biodiesel BTC and small agri-biodiesel producers tax credit On January 3, 2013, the BTC was retroactively reinstated for 2012 and extended through December 31, 2013. This action resulted in FutureFuel’s biodiesel blending activities from January 1, 2012 to December 31, 2012 qualifying for this credit. The retroactive credit for 2012 totaled $2,535. As a result of its passage into law subsequent to year-end 2012, the retroactive credit was recognized as a reduction in cost of goods sold in the first quarter of 2013. On December 22, 2014, the BTC was retroactively reinstated for 2014 and expired on December 31, 2014. The retroactive credit for 2014 totaled $33,031, and $28,954 was recognized as a reduction in cost of goods sold in the fourth quarter of 2014, with the remainder recognized as a reduction of cost of goods sold in 2015. Pursuant to the terms of certain 2014 sales commitments, $18,628 of the 2014 retroactive credit was owed to customers. This obligation was recognized as a reduction in sales revenue in the fourth quarter of 2014. The BTC expired on December 31, 2014 and was reinstated on December 18, 2015. The retroactive credit for 2015 totaled $30,895 and was recognized as a reduction of cost of goods sold in the fourth quarter of 2015. Pursuant to the terms of certain 2015 sales commitments, $16,544 of the 2015 retroactive credit was owed to customers. This obligation was recognized as a reduction in sales revenue in the fourth quarter of 2015. The BTC is set to expire December 31, 2016. On January 3, 2013, a tax credit for small agri-biodiesel producers with production capacity not in excess of 60 million gallons of $0.10 per gallon for the first 15 million gallons of agri-biodiesel sold was retroactively reinstated for 2012 and extended through December 31, 2013. This action resulted in FutureFuel’s biodiesel production activities from January 1, 2012 to December 31, 2012 qualifying for this credit. The retroactive income tax credit for 2012 totaled $1,500. As a result of its passage into law subsequent to year-end 2012, the retroactive income tax credit was recognized as a component of the provision for income taxes in the first quarter of 2013. This credit is part of the bill from which the BTC mentioned above was reinstated for 2014 and 2015. As such, this tax credit, totaling $1,500, was also retroactively reinstated for 2015 and 2014. The small agri-biodiesel producers’ credit is set to expire December 31, 2016.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	13) Stock based compensation The board of directors of FutureFuel adopted an omnibus incentive plan which was approved by the shareholders of FutureFuel at its 2007 annual shareholder meeting on June 26, 2007. The purpose of the plan is to: ● Encourage ownership in FutureFuel by key personnel whose long-term employment with or engagement by FutureFuel or its subsidiaries is considered essential to its continued progress and, thereby, encourage recipients to act in FutureFuel’s shareholders’ interests and share in its success; ● Encourage such persons to remain in FutureFuel’s employ or in the employ of its subsidiaries; and ● Provide incentives to persons who are not FutureFuel employees to promote FutureFuel’s success. The plan authorizes FutureFuel to issue stock options (including incentive stock options and nonqualified stock options), stock awards, and stock appreciation rights. Eligible participants in the plan include: (i) members of FutureFuel’s board of directors and its executive officers; (ii) regular, active employees of FutureFuel and any of its subsidiaries; and (iii) persons engaged by FutureFuel or any of its subsidiaries to render services to FutureFuel or its subsidiaries as an advisor or consultant. Awards under the plan are limited to shares of FutureFuel’s common stock, which may be shares acquired by FutureFuel, including shares purchased in the open market, or authorized but un-issued shares. Awards are limited to 10% of the issued and outstanding shares of FutureFuel’s common stock in the aggregate. The plan became effective upon its approval by FutureFuel’s shareholders on June 26, 2007 and continues in effect for a term of ten years thereafter unless amended and extended by FutureFuel or unless otherwise terminated. FutureFuel recognizes compensation expense in its financial statements for stock based options based upon the grant-date fair value over the requisite service period. In May 2014, FutureFuel issued a restricted stock award of 250,000 shares to Paul A. Novelly, FutureFuel’s Chief Executive Officer. The restricted shares vest in three annual installments on the first, second, and third anniversaries of the grant date as service to the company is fulfilled. The total expense for the award was $4,195 and will be recognized into expense equally over the three years. In July 2014, FutureFuel issued a restricted stock award of 125,000 shares to Paul M. Flynn, FutureFuel’s Executive Vice President of Business and Marketing, upon commencement of employment on September 2, 2014. Twenty percent of the shares vested immediately. The remaining shares vest equally over the remaining annual installments on the first, second, third, and fourth anniversaries of the commencement of employment as service to the company is fulfilled. The total expense for the award was $2,136, with 20% recognized immediately and the remainder to be recognized into expense equally over the four years. No stock awards were issued in 2015. In December 2014, FutureFuel granted a total of 90,000 stock options to select members of management. The options awarded have an exercise price equal to the mean between the highest and lowest quoted sales prices for FutureFuel’s common stock as of the grant date as reported by the New York Stock Exchange. The options awarded vest annually in equal increments over three years and expire on December 2, 2019. FutureFuel has utilized the Black Scholes Merton option pricing model, which relies on certain assumptions, to estimate the fair value of the options it granted. In December 2015, FutureFuel granted a total of 30,000 stock options to new members of the Board of Directors. The options awarded in 2015 have an exercise price equal to the mean between the highest and lowest quoted sales prices for FutureFuel’s common stock as of the grant date as reported by the New York Stock Exchange. All options awarded in 2015 vested immediately upon grant and expire in December 2020. FutureFuel has utilized the Black Scholes Merton option pricing model, which relies on certain assumptions, to estimate the fair value of the options it granted. The assumptions used in the determination of the fair value of the options granted are provided in the following table: Assumptions December 2015 Options December 2014 Options Expected volatility rate 43.08% 41.48% Expected dividend yield 1.72% 4.23% Risk-free interest rate 1.67% 1.25% Expected forfeiture rate 0.00% 0.00% Expected term in years 4.5 4.5 The volatility rate for the options granted in 2015 and 2014 were derived from the historical stock price volatility of FutureFuel’s common stock over the same time period as the expected term of each stock option award. The volatility rate is derived by a mathematical formula utilizing the daily closing stock price data over the expected term. The expected dividend yield is calculated using FutureFuel’s expected dividend amount at the date of the option grant over the expected term divided by the fair market value of FutureFuel’s common stock. The risk-free interest rate is derived from the United States Federal Reserve’s published interest rates of yields for the same time period as the expected term. FutureFuel has only included share-based awards expected to vest in share-based compensation expense. The estimated forfeiture rates are based upon FutureFuel’s expected rate of forfeiture and are excluded from the quantity of awards included in share-based compensation expense. For the years ended December 31, 2015, 2014, and 2013, total share-based compensation expense (before tax) totaled $2,043, $1,440, and $0, respectively. In the years ended December 31, 2015, 2014, and 2013, this balance was recorded as an element of selling, general, and administrative expenses. As of December 31, 2015, $3,069 of total unrecognized compensation expense related to restricted stock awards is expected to be recognized over a weighted average period of 1.86 years. As of December 31, 2015, $158 of total unrecognized compensation expense related to stock options is expected to be recognized over a weighted average period of 1.92 years. Each amount will be adjusted for any future changes in estimated forfeitures. The weighted average fair value of options granted in 2015 was $4.55 per option, in 2014, it was $2.78 per option, and no options were granted in 2013. A summary of the activity of FutureFuel’s stock options and awards for the period beginning January 1, 2013 and ending December 31, 2015 is presented below.

The aggregate intrinsic values of total options outstanding and at December 31, 2015 and 2014 were $378 and $299, respectively. The aggregate intrinsic values of total options exercisable at December 31, 2015 and 2014 were $248 and $148, respectively. Intrinsic value is the amount by which the last trade price of the common stock closest to December 31, 2015 and December 31, 2014, respectively, exceeded the exercise price of the options granted. In 2015, FutureFuel realized gross proceeds from stock option exercises of $0 and realized a net tax benefit of $5. All of the options exercised in 2015 were exercised on a cashless basis and resulted in 16,556 shares of FutureFuel’s common stock being returned to FutureFuel by the stock option holder. All of the stock awards that vested were issued on a cashless basis and resulted in 10,000 shares of FutureFuel’s common stock being returned to FutureFuel by the stock award holder. Such shares were returned to satisfy payment of the exercise price along with minimum tax requirements. Such minimum tax requirements totaled $120.

Income Tax Disclosure [Text Block]	14) Provision for income taxes The following table summarizes the provision for income taxes: 2015 2014 2013 Income before taxes - U.S. $ 51,869 $ 67,345 $ 97,351 Provision for income taxes: Current 7,475 8,455 22,933 Deferred (2,283 ) 3,858 (2,200 ) State and other Current 487 1,306 2,829 Deferred (231 ) 526 (245 ) Total $ 5,448 $ 14,145 $ 23,317 Differences between the provision for income taxes computed using the U.S. federal statutory income tax rate were as follows: 2015 2014 2013 Amount computed using the statutory rate of 35% $ 18,154 $ 23,571 $ 34,072 Section 199 manufacturing deduction (163 ) - (2,092 ) Agri-biodiesel production credit (975 ) (975 ) (1,950 ) Federal excise tax benefit (9,958 ) (10,344 ) (9,566 ) State excise tax benefit (792 ) (2,409 ) (2,067 ) Credit for increasing research activities (51 ) (80 ) (180 ) Alternative fueling equipment credit - (2 ) (23 ) Tax exempt interest income - - (2 ) State income taxes, net 695 3,189 3,983 Tax (benefit)/expense recorded as a decrease/increase in unrecognized tax benefit (747 ) 1,309 1,718 Other (715 ) (114 ) (576 ) Provision for income taxes $ 5,448 $ 14,145 $ 23,317 The effective tax rates for the years December 31, 2015 and 2014 reflect FutureFuel’s expected tax rate on reported operating earnings before income tax. In 2015, the biodiesel BTC formed a larger proportion of FutureFuel’s net income than in prior years. This increase in proportion combined with the income tax treatment of the BTC served to reduce FutureFuel’s effective income tax rate in 2015 relative to prior years. The significant components of deferred tax assets and liabilities were as follows as of December 31: 2015 2014 Deferred tax assets Compensation $ 249 $ 1,005 Inventory reserves 1,244 628 Self insurance 111 88 Asset retirement obligation 299 289 Deferred revenue 9,993 10,110 Stock based compensation 144 244 Other - 81 Total deferred tax assets 12,040 12,445 Deferred tax liabilities Available for sale securities (1,075 ) (2,618 ) Derivative instruments (1,348 ) (488 ) Accrued expenses (656 ) (592 ) LIFO inventory (5,163 ) (6,062 ) Depreciation (39,930 ) (41,520 ) Other (45 ) (2,609 ) Total deferred tax liabilities (48,217 ) (53,889 ) Valuation allowance - - Net deferred tax liabilities $ (36,177 ) $ (41,444 ) 2015 2014 As recorded in the consolidated balance sheet Current deferred tax liability $ (7,060 ) $ (11,003 ) Noncurrent deferred tax liability (29,117 ) (30,441 ) Net deferred tax liabilities $ (36,177 ) $ (41,444 ) In 2013, as a result of then recently issued technical guidance from the U.S. Internal Revenue Service, FutureFuel changed its position related to the benefit from the biodiesel BTC to exclude this credit from taxable income for the years 2010 through 2013. This change had a significant impact on FutureFuel’s provision for income taxes in the fourth quarter of 2013. This benefit reduced FutureFuel’s provision for income taxes by $11,633 in 2013, with $7,755 related to the years 2010 through 2012 and $3,878 related to 2013. This same treatment was followed in 2014 and 2015 when the biodiesel BTC was retroactively reinstated for 2014 and 2015 in December of 2014 and 2015, respectively. The biodiesel BTC was extended through the end of 2016 as part of the 2015 tax extenders package. FutureFuel’s unrecognized tax benefits totaled $4,588 and $2,981 at December 31, 2015 and 2014, respectively. The following table summarizes FutureFuel’s unrecognized tax benefits activity. 2015 2014 2013 Beginning balance $ 2,981 $ 1,718 $ - Increases to tax positions taken in the current year 1,471 1,255 917 Increases to tax positions taken in a prior year 3,117 8 801 Decrease due to resolution of tax positions taken in a prior year (2,981 ) - - Balance at December 31 $ 4,588 $ 2,981 $ 1,718 FutureFuel does not expect its unrecognized tax benefits to change significantly over the next 12 months. FutureFuel records interest and penalties net as a component of income tax expense. FutureFuel accrued balances of $61 and $46 at December 31, 2015 and 2014, respectively, for interest or tax penalties. FutureFuel and its subsidiaries file tax returns in the U.S. federal jurisdiction and with various state jurisdictions. In general, FutureFuel is subject to U.S., state, and local examinations by tax authorities from 2012 forward . In the second quarter of 2015, the IRS completed its audit of FutureFuel’s 2010 through 2012 amended federal income tax returns. FutureFuel was successful in recovering the benefits previously unrecorded in its financial statements. Also during the second quarter of 2015, FutureFuel received notice of rejection from an administrative law judge in The Arkansas Office of Hearings and Appeals regarding FutureFuel’s 2010 through 2012 amended state income tax returns.

Deferred Revenue Disclosure [Abstract]
Deferred Revenue Disclosure [Text Block]	15) Deferred revenue and contingent liability FutureFuel has signed contracts with customers to construct plant and other related assets on FutureFuel’s property for the manufacture of custom chemicals. The cost of the construction has been funded by the customers. Additionally, FutureFuel has been awarded grants from governmental agencies related to the construction of production equipment and infrastructural improvements. As these customers and governmental agencies have paid for such projects, FutureFuel has recorded such amounts as deferred revenue. Deferred revenue totaled $18,588 at December 31, 2015, with $2,680 classified as a current liability and $15,908 classified as a noncurrent liability. Deferred revenue totaled $17,867 at December 31, 2014, with $1,940 classified as a current liability and $15,927 classified as a noncurrent liability. The following table summarizes FutureFuel’s deferred revenue activity: 201 5 2014 Beginning balance $ 17,867 $ 20,391 Amortization (2,468 ) (6,790 ) Additions 3,365 4,283 Impairment (176 ) (17 ) Balance at December 31 $ 18,588 $ 17,867 One of the grants from a governmental agency is contingent upon FutureFuel meeting certain employment goals. If these goals are not reached, FutureFuel may be required to remit a portion of the grant back to the agency. As a result of this provision, FutureFuel has recorded a contingent liability for the monies received under this grant. This balance totaled $1,151 and $1,151 at December 31, 2015 and 2014.

Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	16) Stockholders’ equity On July 12, 2006, Viceroy and its founding shareholders entered into a registration rights agreement pursuant to which the holders of the majority of founding shares and shares of common stock included in the units purchased in Viceroy’s July 2006 offering by a director or his designees are entitled to make up to two demands that Viceroy register with the SEC their founding shares and the shares included in the units purchased in Viceroy’s July 2006 offering. The holders of the majority of such shares can elect to exercise these registration rights at any time after the date on which Viceroy has become a reporting company under the Securities Exchange Act of 1934, as amended (“Exchange Act”), and such shares have been released from any applicable escrow agreement and lock-in deeds. In addition, those shareholders have certain “piggyback” registration rights on registration statements filed subsequent to the date on which such shares are released from escrow or other lock up arrangements. Viceroy agreed to bear the expenses incurred in connection with the filing of any such registration statements. There are 16,250,000 shares of Viceroy’s common stock subject to this registration rights agreement. On February 10, 2011, FutureFuel filed with the SEC a Form S-3 Registration Statement commonly referred to as a “shelf registration” whereby FutureFuel registered shares of its common stock, preferred stock, warrants, rights, and units which it might issue in the future in an aggregate amount not to exceed $50,000. This registration statement became effective on March 10, 2011. Pursuant to this registration statement, on May 11, 2011, FutureFuel commenced an “At-the-Market” offering under which FutureFuel could from time to time over the succeeding three years sell up to 3,000,000 shares of its common stock. During 2011, FutureFuel issued 1,313,985 shares of its common stock pursuant to this “At-the-Market” offering for a net aggregate purchase price of $15,763, and paid its underwriters $488 as compensation with respect to such issuances. During 2012, FutureFuel issued 91,143 shares of its common stock pursuant to this offering for a net aggregate purchase price of $1,074, and paid its underwriters $33 as compensation with respect to such issuances. During 2013, FutureFuel issued 1,594,872 shares of its common stock pursuant to this offering for a net aggregate purchase price of $19,292, and paid its underwriters $599 as compensation with respect to such issuances. On February 6, 2013, FutureFuel announced the completion of the sale of shares of its common stock under the At-the-Market offering. An aggregate 3,000,000 shares were sold in open market trading for aggregate gross proceeds of approximately $37,247, resulting in net proceeds of approximately $36,127 after deducting commissions and fees.

Cost of goods sold related to these sales includes variable costs and allocated fixed costs. Natural gas purchases FutureFuel utilizes natural gas to generate steam for its manufacturing process and to support certain of its air and waste treatment utilities. This natural gas is purchased through an affiliate provider of natural gas marketing services. Expenses related to these purchases include the cost of the natural gas only; transportation charges are paid to an independent third party. Income tax and consulting services An affiliate provides professional services to FutureFuel, primarily in the area of income tax preparation and consulting. FutureFuel also receives certain finance and accounting expertise from this affiliate as requested. Expenses related to these services are comprised of an agreed quarterly fee plus reimbursement of expense, at cost. Distribution and related services Distribution and related services are comprised of barge transportation and related unloading charges for petrodiesel that were arranged and paid by an affiliate and subsequently rebilled to FutureFuel. Additionally, FutureFuel leases oil storage capacity from an affiliate under a storage and throughput agreement. This agreement provides for the storage of biodiesel, diesel or biodiesel/petrodiesel blends, methanol, and biodiesel feedstocks in above-ground storage tankage at designated facilities of the affiliate. Expenses related to this agreement include monthly lease charges, generally on a per barrel basis, and associated heating, throughput, and other customary terminalling charges.

Note 20 - Segment Information

Note 20 - Segment Information	12 Months Ended

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	20) Segment information FutureFuel has two reportable segments organized along similar product lines – chemicals and biofuels. The accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 2. Chemicals FutureFuel’s chemicals segment manufactures diversified chemical products that are sold externally to third party customers. This segment is comprised of two components: “custom manufacturing” (manufacturing chemicals for specific customers) and “performance chemicals” (multi-customer specialty chemicals). Biofuels FutureFuel’s biofuels business segment manufactures and markets biodiesel. Biodiesel revenues are generated through the sale of biodiesel to customers through FutureFuel’s distribution network at the Batesville Plant, through distribution facilities available at leased oil storage facilities, and through a network of remotely located tanks. Results of the biofuels business segment also reflect the sale of biodiesel blends with petrodiesel, petrodiesel with no biodiesel added, RINs, biodiesel production byproducts, and the purchase and sale of other petroleum products on common carrier pipelines. Summary of long-lived assets and revenues by geographic area All of FutureFuel’s long-lived assets are located in the U.S. Most of FutureFuel’s sales are transacted with title passing at the time of shipment from the Batesville Plant, although some sales are transacted based on title passing at the delivery point. While many of FutureFuel’s chemicals are utilized to manufacture products that are shipped, further processed, and/or consumed throughout the world, the chemical products, with limited exceptions, generally leave the United States only after ownership has transferred from FutureFuel to the customer. Rarely is FutureFuel the exporter of record, never is FutureFuel the importer of record into foreign countries, and FutureFuel is not always aware of the exact quantities of its products that are moved into foreign markets by its customers. FutureFuel does track the addresses of its customers for invoicing purposes and uses this address to determine whether a particular sale is within or without the United States. FutureFuel’s revenues for the years ended December 31, 2015, 2014, and 2013 attributable to the United States and foreign countries (based upon the billing addresses of its customers) were as follows. Fiscal Year United States All Foreign Total December 31, 2015 $ 297,415 $ 2,196 $ 299,611 December 31, 2014 $ 334,210 $ 7,628 $ 341,838 December 31, 2013 $ 430,096 $ 14,823 $ 444,919 For the years ended December 31, 2015, 2014, and 2013, revenues from Mexico accounted for 0%, 1%, and 3%, respectively, of total revenues. Other than Mexico, revenues from a single foreign country during 2015, 2014, or 2013 did not exceed 1% of total revenues. Summary of business by segment Twelve months ended: 2015 2014 2013 Revenues: Custom chemicals $ 108,160 $ 127,956 $ 147,095 Performance chemicals 17,688 18,190 14,406 Chemicals Revenues 125,848 146,146 161,501 Biofuels Revenues 173,763 195,692 283,418 Total Revenues $ 299,611 $ 341,838 $ 444,919 Segment gross profit: Chemicals $ 35,452 $ 46,062 $ 54,708 Biofuels 21,594 19,911 45,457 Total gross profit 57,046 65,973 100,165 Corporate expenses 10,075 9,845 9,911 Income before interest and taxes 46,971 56,128 90,254 Interest and other income 5,213 6,877 5,875 Interest and other expense (315 ) 4,340 1,222 Provision for income taxes (5,448 ) (14,145 ) (23,317 ) Net income $ 46,421 $ 53,200 $ 74,034 Depreciation is allocated to segment costs of goods sold based on plant usage. The total assets and capital expenditures of FutureFuel have not been allocated to individual segments as large portions of these assets are shared to varying degrees by each segment, causing such an allocation to be of little value. Gross margins for the biofuels segment for the year ended December 31, 2015 were favorably impacted by the receipt of approximately $147 awarded to FutureFuel under the United States Department of Agriculture Section 9005 – Advanced Biofuel Producers program in 2015. This award totaled $420 and $886 in 2014 and 2013, respectively. Based on the characteristics of this award, FutureFuel recognizes the income from the award in the period the funding is received. The biofuels segment also includes activity on common carrier pipelines.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	21) Fair value measurements Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Fair value accounting pronouncements also include a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of FutureFuel. Unobservable inputs are inputs that reflect FutureFuel’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy is broken down into three levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following table provides information by level for assets and liabilities that are measured at fair value, on a recurring basis.

Disclosure Text Block [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	25) Recently issued accounting standards In May 2014, the FASB and International Accounting Standards Board jointly issued new principles-based accounting guidance for revenue recognition that will supersede virtually all existing revenue guidance. The core principle of this guidance is that an entity should 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 and services. To achieve the core principle, the guidance establishes the following five steps: 1) identify the contract(s) with a customer, 2) identify the performance obligation in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligations in the contract, and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also details the accounting treatment for costs to obtain or fulfill a contract. Lastly, disclosure requirements have been enhanced to provide sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. However, in a July 2015 meeting, the FASB affirmed its proposal to defer the effective date by one year. The provisions of the ASU are to be applied retrospectively; early adoption prior to the original effective date is not permitted. FutureFuel is currently evaluating the impact on its financial position, results of operations, and related disclosures. In April 2015, the Financial Accounting Standards Board (the “FASB”) issued new guidance for debt issuance costs as a part of the simplification and productivity initiative. Under this guidance, debt issuance costs will be presented as a direct reduction from the carrying amount of the debt liability, consistent with the presentation of debt discounts. The amortization of debt issuance costs will be reported as interest expense. The recognition and measurement guidance for debt issuance costs is not affected by the amendment. In August 2015, the FASB released clarifying guidance for debt issuance costs related to line-of-credit arrangements that may be deferred and for presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The new guidance is to be applied on a retrospective basis and reported as a change in an accounting principle. This guidance is effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. Early adoption is permitted for financial statements that have not been previously issued. FutureFuel has shown the payment of these debt issuance costs as an asset at December 31, 2015. In July 2015, the Financial Accounting Standards Board issued new guidance that requires inventory not measured using either the last in, first out (LIFO) or the retail inventory method to be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation. The new standard will be effective for periods on or after December 15, 2016 and will be applied prospectively. Early adoption is permitted. FutureFuel is currently evaluating the impact on its financial position, results of operations, and related disclosures. In November 2015, the FASB issued guidance under the simplification and productivity initiative for presentation of deferred income tax liabilities and assets. This guidance simplifies the presentation of deferred income taxes such that deferred tax liabilities and assets are to be classified as noncurrent in a classified balance sheet. The update does not amend the current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted as of the beginning of an interim or annual reporting period and may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company has elected not to early adopt the new guidance as of the balance sheet date due to the insignificance of the change. As of December 31, 2015, the impact to the company would be a reclassification of $7,060 from current deferred tax liability to long-term deferred tax liability. In February 2016, a pronouncement was issued that creates new accounting and reporting guidelines for leasing arrangements. The new guidance requires organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease primarily will depend on its classification as a finance or operating lease. The guidance also requires new disclosures in order to help users of financial statements better understand the amount, timing, and uncertainty of cash flows arising from leases. The new standard is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, with early application permitted. The new standard is to be applied using a modified retrospective approach. FutureFuel is currently evaluating the impact of the new pronouncement on its financial statements.

Disclosure Text Block Supplement [Abstract]
Asset Impairment Charges [Text Block]	27) Asset impairment On July 29, 2013, FutureFuel received notice from a chemicals segment customer for the intermediate anode powder that the customer will terminate the contract in accordance with its terms effective August 9, 2014. This contract subsequently terminated on August 9, 2014 without any additional material being produced or sold in 2014. As a result of the cancelation notice, FutureFuel assessed the carrying values of its fixed assets and deferred revenue associated with this product and recorded an impairment loss of $17,580 for the equipment based on the scrap value method less disposition costs and recorded a reduction of deferred revenue as an element of cost of goods sold slightly offset by other expenses in the amount of $16,160 in 2013. The net impact of this impairment recorded in cost of goods sold for 2013 was $1,420. FutureFuel’s customer remitted payment for all remaining minimum take or pay quantities per the terms of the sales agreement in 2014. FutureFuel also recognized the shortfall payment from 2013 in 2014. Such amounts totaled $4,176 and $4,640 respectively, and were recorded as a component of chemical segment revenue in 2014.

Disclosure Text Block Supplement [Abstract]
Legal Matters and Contingencies [Text Block]	28) Legal proceedings FutureFuel is not a party to, nor is any of its property subject to, any material pending legal proceedings, other than ordinary routine litigation incidental to its business. However, from time to time, FutureFuel may be a party to, or a target of, lawsuits, claims, investigations, and proceedings, including product liability, personal injury, asbestos, patent and intellectual property, commercial, contract, environmental, antitrust, health and safety, and employment matters, which FutureFuel expects to be handled and defended in the ordinary course of business. While FutureFuel is unable to predict the outcome of any matters currently pending, FutureFuel does not believe that the ultimate resolution of any such pending matters will have a material adverse effect on its overall financial condition, results of operations, or cash flows. However, adverse developments could negatively impact earnings or cash flows in future periods.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Consolidation The accompanying consolidated financial statements include the accounts of FutureFuel and its wholly-owned subsidiaries: FutureFuel Chemical Company; FFC Grain, L.L.C., which was formed in 2009 to acquire a granary in Marianna, Arkansas; FutureFuel Warehouse Company, L.L.C., which was formed in 2011 to acquire a warehouse in Batesville, Arkansas; and Legacy Regional Transport, L.L.C., which was formed in 2012 and operates FutureFuel’s truck fleet. All significant intercompany transactions have been eliminated.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents Cash equivalents consist of highly liquid investments with maturities of three months or less when purchased and are carried at cost, which approximates market. FutureFuel places its temporary cash investments with high credit quality financial institutions. At times, bank deposits may be in excess of the Federal Deposit Insurance Corporation insurance limit.
Receivables, Policy [Policy Text Block]	Accounts receivable, allowance for doubtful accounts and credit risk Accounts receivable are recorded at the invoiced amount and do not bear interest. FutureFuel has established procedures to monitor credit risk and has not experienced significant credit losses in prior years. Accounts receivable have been reduced by an allowance for amounts that may be uncollectible in the future. This estimated allowance is based upon management’s evaluation of the collectability of individual invoices and is based upon management’s evaluation of the financial condition of its customers and historical bad debt experience. Write-offs are recorded at the time a customer receivable is deemed uncollectible.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Customer concentrations Significant portions of FutureFuel’s sales are made to a relatively small number of customers. All sales of a laundry detergent additive are made to a leading North American consumer products company. Sales of the laundry detergent additive were less than 10% of total revenue for the year ended December 31, 2015 and greater than 10% for the years ended December 31, 2014 and 2013, or $43,927 and $56,596, respectively. Sales to one biodiesel customer totaled $33,255, $62,994, and $135,273 for the years ended December 31, 2015, 2014, and 2013, respectively. Additionally, sales of biodiesel, petrodiesel, petrodiesel blends, and other petroleum products to a related party totaled $64,981, $39,090, and $9,420 for the years ended December 31, 2015, 2014, and 2013, respectively. See Note 19 below.
Inventory, Policy [Policy Text Block]	Inventory FutureFuel determines the cost of substantially all raw materials and finished goods inventories by the last-in, first-out (“LIFO”) method. FutureFuel writes down its inventories for estimated obsolescence or unmarketable inventory equal to the difference between the carrying value of inventory and the estimated market value based upon current demand and market conditions.
Derivatives, Policy [Policy Text Block]	Financial and derivative instruments The carrying values of cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses and other current liabilities approximate their fair values due to the short-term maturities of these instruments. FutureFuel records all derivative instruments at fair value. Fair value is determined by using the closing prices of the derivative instruments on the New York Mercantile Exchange at the end of an accounting period. Changes in fair value of the derivative instruments are recorded in the statements of operations as a component of cost of goods sold. FutureFuel maintains a margin account with a broker to collateralize these derivative instruments. In order to manage commodity price risk caused by market fluctuations in biofuel prices, future purchases of feedstock used in our biodiesel production, physical feedstock, finished product inventories attributed to the process, and other petroleum products purchased or sold, we may enter into exchange traded commodity futures and options contracts. We account for these derivative instruments in accordance with ASC 815-20-25, Derivatives and Hedging, Hedging-General, Recognition. Under this standard, the accounting for changes in the fair value of a derivative instrument depends upon whether it has been designated as an accounting hedging relationship and, further, on the type of hedging relationship. To qualify for designation as an accounting hedging relationship, specific criteria must be met and appropriate documentation maintained. We had no derivative instruments that qualified under these rules as designated accounting hedges in 2015 or 2014. Changes in the fair value of our derivative instruments are recognized at the end of each accounting period and recorded in the statement of operations as a component of cost of goods sold. Our immediate recognition of derivative instrument gains and losses can cause net income to be volatile from period to period due to the timing of the change in value of the derivative instruments relative to the sale of the physical commodity sold. As of December 31, 2015 and 2014, the fair values of our derivative instruments were a net asset in the amount of $3,362 and $68, respectively. They were comprised of short positions of 200 regulated options with a fair value of $(427) and a short position of 631 regulated fixed price futures contracts with a fair value of $3,789 at December 31, 2015. Comparatively, we held a short position of 350 regulated options with a value of $(794) and a short position of 225 regulated fixed price future commitments with a value of $862 at December 31, 2014.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, plant and equipment Property, plant, and equipment is carried at cost. Maintenance and repairs are charged to earnings; replacements and betterments are capitalized. When FutureFuel retires or otherwise disposes of an asset, it removes the cost of such asset and related accumulated depreciation from the accounts. FutureFuel records any profit and loss on retirement or other disposition in earnings. Depreciation is provided using the straight-line method over the following estimated useful lives: Building & building equipment (years) 20 - 39 Machinery and equipment (years) 3 – 33 Transportation equipment (years) 5 – 33 Other (years) 5 – 33
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of assets Long-lived tangible assets FutureFuel evaluates the carrying value of long-lived tangible assets when events or changes in circumstances indicate that the carrying value may not be recoverable. Such events and circumstances include, but are not limited to, significant decreases in the market value of the asset, adverse changes in the extent or manner in which the asset is being used, significant changes in business climate, or current or projected cash flow losses associated with the use of the assets. The carrying value of a long-lived asset is considered impaired when the total projected undiscounted cash flows from such assets are separately identifiable and are less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. For long-lived assets to be held for use in future operations and for fixed (tangible) assets, fair value is determined primarily using either the projected cash flows discounted at a rate commensurate with the risk involved or an appraisal. For long-lived assets to be disposed of by sale or other than sale, fair value is determined in a similar manner, except that fair values are reduced for disposal costs. Indefinite-lived in tangible asset Intangible assets with indefinite lives are not amortized, but are reviewed for impairment at least annually or whenever events or circumstances indicate the carrying value of the asset may not be recoverable. The Company performs annual impairment tests of the intangible assets during the fourth quarter of each fiscal year and assesses qualitative factors to determine the likelihood of impairment. The Company’s qualitative analysis includes, but is not limited to, assessing the changes in macroeconomic conditions, legal and regulatory environment, industry and market conditions, financial performance, and any other relevant events or circumstances specific to the intangible asset. If it is more likely than not that the fair value of the intangible asset is greater than the carrying value, no further testing is required. Otherwise, the Company will apply the quantitative impairment test method. In performing the Company's qualitative analysis, the Company determined that it was more likely than not that the indefinite-lived intangible asset's fair value was greater than the carrying value.
Revenue Recognition, Deferred Revenue [Policy Text Block]	Deferred revenue FutureFuel has signed contracts with customers to construct plant and related assets on FutureFuel’s property for the manufacture of custom chemicals. The cost of construction has been funded by the customers with title and risk of loss to the equipment residing with FutureFuel. Reimbursements are recognized as deferred revenue and are amortized over the expected life of the customer relationship starting upon the completion of construction and the asset being placed into service. Additionally, FutureFuel has been awarded grants from governmental agencies related to the construction of production equipment and infrastructural improvements at its plant site. The cost of construction of these projects has been either funded by the governmental agencies directly or funded by FutureFuel who has then been reimbursed by the governmental agencies. Direct payments and reimbursements for construction costs have been recognized as deferred revenue and will be amortized into earnings over the expected life of the applicable customer relationship or the life of the asset if no direct customer relationship is tied to the asset. Such amortization will not begin until the asset has been placed into service and all contingencies associated with the grants are fulfilled.
Asset Retirement Obligations, Policy [Policy Text Block]	Asset retirement obligations FutureFuel establishes reserves for closure/post-closure costs associated with the environmental and other assets it maintains. Environmental assets include but are not limited to waste management units such as destructors, landfills, storage tanks, and boilers. When these types of assets are constructed or installed, a liability is established for the future costs anticipated to be associated with the closure of the site based on an expected life of the environmental assets, the applicable regulatory closure requirements, and FutureFuel’s environmental policies and practices. These expenses are charged into earnings over the estimated useful life of the assets. Currently, FutureFuel estimates the useful life of each individual asset up to 35 years. Changes made in estimates of the asset retirement obligation costs or the estimate of the useful lives of these assets are reflected in earnings as an increase or decrease in the period such changes are made. Environmental costs are capitalized if they extend the life of the related property, increase its capacity, and/or mitigate or prevent future contamination. The cost of operating and maintaining environmental control facilities is charged to expense.
Income Tax, Policy [Policy Text Block]	Income taxes Income taxes are accounted for using the asset and liability method. Under this method, income tax assets and liabilities are recognized for temporary differences between financial statement carrying amounts of assets and liabilities and their respective income tax basis. A future income tax asset or liability is estimated for each temporary difference using enacted and substantively enacted income tax rates and laws expected to be in effect when the asset is realized or the liability settled. A valuation allowance is established, if necessary, to reduce any future income tax asset to an amount that is more likely than not to be realized. FASB ASC Topic 740, Income Taxes
Revenue Recognition, Policy [Policy Text Block]	Revenue recognition For most product sales, revenue is recognized when product is shipped from our facilities and risk of loss and title have passed to the customer, which is in accordance with our customer contracts and the stated shipping terms. All custom manufactured products are manufactured under written contracts. Performance chemicals and biofuels are usually sold pursuant to the terms of written purchase orders. In general, customers do not have any rights of return, except for quality disputes. However, all of our products are tested for quality before shipment, and historically returns have been inconsequential. FutureFuel does not offer rebates or other warranties. Bill and hold transactions for 2015, 2014, and 2013 related to three specialty chemical customers in 2015, four in 2014, and six in 2013, whereby revenue was recognized in accordance with contractual agreements based on product produced and ready for use. These sales were subject to written monthly purchase orders with agreement that production was reasonable. The inventory was custom manufactured and stored at the customer’s request and could not be sold to another buyer. Credit and payment terms for bill and hold transactions are similar to other specialty chemical customers. Sales revenue under bill and hold arrangements totaled $28,740, $31,598, and $44,047 for the years ended December 31, 2015, 2014, and 2013, respectively.
Excise and Sales Taxes [Policy Text Block]	Taxes collected from customers and remitted to governmental authorities Taxes collected from customers and remitted to governmental authorities are excluded from revenues and cost of goods sold.
Shipping and Handling Cost, Policy [Policy Text Block]	Shipping and handling fees Shipping and handling fees related to sales transactions are billed to customers and recorded as sales revenues.
Cost of Sales, Policy [Policy Text Block]	Cost of goods sold and selling, general, and administration expenses Cost of goods sold includes the costs of inventory sold, related purchasing, distribution, and warehousing costs, costs incurred for shipping and handling, and environmental remediation costs. In 2015, 2014 and 2013, the biodiesel tax incentive for blending biodiesel with petroleum diesel is netted with costs of goods sold. The one dollar per gallon blenders’ tax credit (“BTC”) amounted to one cent for each percentage point of vegetable oil or animal fat biodiesel that was blended with petrodiesel. The credit was recognized as it was earned, i.e., when biodiesel blended with petrodiesel was sold or when such credit was made law. This tax credit is set to expire on December 31, 2016. Selling, general, and administration expenses include personnel costs associated with sales, marketing and administration, legal and legal-related costs, consulting and professional services fees, advertising expenses, and other similar costs.
Research and Development Expense, Policy [Policy Text Block]	Research and development All costs identified as research and development costs are charged to expense when incurred.
Public Utilities, Policy [Policy Text Block]	Planned major maintenance activities Expenditures for planned major maintenance activities are recognized as expense as incurred.
Earnings Per Share, Policy [Policy Text Block]	Earnings per share Earnings per share is computed using the two-class method in accordance with ASC 260, Earnings Per Share Contingently issuable shares associated with outstanding service-based restricted stock shares were not included in the earnings per share calculations for the year ended December 31, 2015 and 2014 as the vesting conditions had not been satisfied. No such restricted stock units existed in 2013.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive income Comprehensive income is comprised of net income and other comprehensive income/(losses) (“OCI”). Comprehensive income comprises all changes in stockholders’ equity from transactions and other events and circumstances from non-owner sources. FutureFuel’s OCI is comprised of unrealized gains and losses resulting from its investment in certain marketable securities classified as available for sale (see Note 6). For the year ended December 31, 2015, FutureFuel recorded other comprehensive losses of $2,204, net of income tax benefit of $1,546, on these securities. For the year ended December 31, 2014, FutureFuel recorded other comprehensive losses of $3,177, net of income tax benefit of $1,980, on these securities. For the year ended December 31, 2013, FutureFuel recorded other comprehensive income of $4,839, net of income taxes of $3,018, on these securities. For the year ended December 31, 2015 and 2013, FutureFuel reclassified a portion of its unrealized income related to certain of its available-for-sale securities from OCI to a component of net income as a result of recording an other than temporary impairment. This reclassification totaled $394 and $207, net of income tax benefit of $212 and $129 for the years ended December 31, 2015 and 2013, respectively. No such reclassification was made for the year ended December 31, 2014.
Commitments and Contingencies, Policy [Policy Text Block]	Commitments and contingent liabilities In the ordinary course of its business, FutureFuel enters into supply and sales contracts as deemed commercially desirable. Supply contracts are utilized to ensure the availability of raw materials used in the production process. Sales contracts are utilized to ensure the future sale of produced product. FutureFuel and its operations from time to time may be parties to or targets of lawsuits, claims, investigations, and proceedings including product liability, personal injury, patent and intellectual property, commercial, contract, environmental, health and safety, and environmental matters, which are handled and defended in the ordinary course of business. FutureFuel accrues a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, FutureFuel accrues the minimum amount.
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during a reporting period. Estimates are used when accounting for allowance for doubtful accounts, depreciation, amortization, asset retirement obligations, and income taxes as well as the evaluation of potential losses due to impairments or future liabilities. Actual results could differ materially from those estimates.
Segment Reporting, Policy [Policy Text Block]	Segment reporting FutureFuel identifies operating segments when separate financial information is available that is evaluated regularly by its chief operating decision maker in assessing the performance of those segments and in determining how to allocate resources. FutureFuel has determined that it has two reportable segments organized along product lines -- chemicals and biofuels.
