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 biobased products platform. This included the production of biofuels (biodiesel) and biobased specialty chemical products (biobased solvents, chemicals, and intermediates). In addition to biobased 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, FFC Grain, L.L.C., which was formed in 2009 to acquire a granary in Marianna, Arkansas, FutureFuel Warehouse Company, LLC, 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. Certain prior period amounts have been reclassified to conform to the current period presentation.
	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 collectibility 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 bleach activator are made to a leading North American consumer products company. Sales of the bleach activator totaled $56,596 for the year ended December 31, 2013 and $60,710 for the year ended December 31, 2012. Additionally, all sales of a herbicide and certain other intermediates used in the production of this herbicide are made to one customer. Sales of this herbicide and its intermediates constituted less than 10% of consolidated revenues for the year ended December 31, 2013 and 2012. Sales of biodiesel to one customer totaled $135,273 for the year ended December 31, 2013 and $102,772 for the year ended December 31, 2012.
	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 maintains inventories of biodiesel and utilizes various derivative instruments such as regulated futures and regulated options as an economic hedge to reduce the effects of fluctuations in the prices of biodiesel. These derivative instruments do not qualify for hedge accounting under the specific guidelines of ASC 815-20-25, Derivatives and Hedging, Hedging-General, Recognition. While management believes each of these instruments are entered into in order to effectively manage various market risks, none of the derivative instruments are designated and accounted for as hedges primarily as a result of the extensive record-keeping requirements.
	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.
	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:
	Buildings and building equipment (years)	20	–	39
	Machinery and equipment (years)	3	–	33
	Transportation equipment (years)	5	–	33
	Other (years)	5	–	33
	Customer relationships
	Customer relationships are recorded at acquisition cost and are amortized on a straight-line basis over their estimated useful lives of five years. FutureFuel reviews and evaluates the recoverability of the carrying amounts of its acquired customer contracts annually, or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
	Impairment of assets
	FutureFuel evaluates the carrying value of long-lived 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.
	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 (“ASC 740”), clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.
	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 warranties.
	Bill and hold transactions for 2013 and 2012 related to six specialty chemical customers, and five specialty chemical customers in 2011, 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 $44,047, $50,076, and $59,597 for the years ended December 31, 2013, 2012, and 2011, respectively.
	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 2013 and 2011, the biodiesel tax incentive for blending biodiesel with petroleum diesel is netted from costs of goods sold. The biodiesel tax credit 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. The tax credit terminated on December 31, 2011. On January 3, 2013, the tax credit was retroactively reinstated for 2012 and extended through December 31, 2013 (see Note 3). This tax credit expired and has not been reinstated.
	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
	Basic earnings per share is computed by dividing net income (the numerator) by the weighted average number of outstanding shares (the denominator) for the period. Diluted earnings per share are calculated in accordance with the treasury stock method to determine the dilutive effect of warrants and options. The computation of diluted earnings per share includes the same numerator, but the denominator is increased to include the number of additional common shares from the exercise of warrants and options that would have been outstanding if potentially dilutive common shares had been issued.
	Comprehensive income
	Comprehensive income is comprised of net income and other comprehensive income (“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).

	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 principals 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.

	3)            Reinstatement of biodiesel blenders' tax credit and small agri-biodiesel producers tax credit
	In December 2010, the government of the United States passed into law the retroactive reinstatement of the $1.00 per gallon biodiesel blenders' tax credit. This action resulted in FutureFuel’s biodiesel blending activities from January 1, 2011 to December 31, 2011 qualifying for this credit. The credit related to 2011 activity was recorded as a reduction to cost of goods sold in the 2011. The blenders' credit expired on December 31, 2011.
	On January 3, 2013, the blenders' credit 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 yearend 2012, the retroactive credit was recognized as a reduction in cost of goods sold in the first quarter of 2013. The blenders' credit expired again on December 31, 2013 and has not been reinstated.
	On December 31, 2011, a tax credit for small agri-biodiesel producers with production capacity not in excess of 60 million gallons expired. This credit had totaled $0.10 per gallon for the first 15 million gallons of agri-biodiesel sold. On January 3, 2013, the small agri-biodiesel producers credit 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 yearend 2012, the retroactive income tax credit was recognized as a component of the provision for income taxes in the first quarter of 2013. The income tax credit for 2013 totals $1,500. The small agri-biodiesel producers credit expired December 31, 2013 and has not been reinstated.

	5)            Derivative instruments
	FutureFuel is exposed to certain risks relating to its ongoing business operations. Commodity price risk is the primary risk managed by using derivative instruments. Regulated fixed price futures and option contracts are utilized to manage the price risk associated with future purchases of feedstock used in FutureFuel’s biodiesel production along with physical feedstock and finished product inventories attributed to this process.
	FutureFuel recognizes all derivative instruments as either assets or liabilities at fair value in its consolidated balance sheet. FutureFuel’s derivative instruments do not qualify for hedge accounting under the specific guidelines of ASC 815-20-25, Derivatives and Hedging, Hedging-General, Recognition. While management believes each of these instruments are entered into in order to effectively manage various risks, none of the derivative instruments are designated and accounted for as hedges primarily as a result of the extensive record keeping requirements.
	The fair value of FutureFuel’s derivative instruments is determined based on the closing prices of the derivative instruments on relevant commodity exchanges at the end of an accounting period. Realized and unrealized gains and losses on derivative instruments and changes in fair value of the derivative instruments are recorded in the statement of operations as a component of cost of goods sold, and amounted to a gain/(loss) of $1,151, $4,528, and $(20) for the years ended December 31, 2013, 2012, and 2011, respectively.
	The volumes and carrying values of FutureFuel’s derivative instruments were as follows at December 31:
		Asset/(Liability)
		2013						2012
		Quantity (contracts) Long/ (Short)			Fair Value			Quantity (contracts) Long/ (Short)			Fair Value

	The margin account maintained with a broker to collateralize these derivative instruments carried an account balance of $479 and $1,853 at December 31, 2013 and 2012, respectively, and is classified as other current assets in the consolidated balance sheet. The carrying values of the margin account and of the derivative instruments are included, net, in other current assets.

	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 April 2011, FutureFuel granted a total of 80,000 stock options to members of its board of directors and a total of 40,000 stock options to selected members of its management. All options awarded in April 2011 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 granted in April 2011 vested immediately upon grant and expire on April 29, 2016. 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 April 2012, FutureFuel granted a total of 80,000 stock options to members of its board of directors and a total of 40,000 stock options to selected members of its management. Additionally, in August 2012, FutureFuel granted a total of 10,000 stock options to a consultant. The options awarded in 2012 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 2012 vested immediately upon grant. The options awarded in April 2012 expire on April 10, 2017 and the options awarded in August 2012 expire August 22, 2017. 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.
	No options were awarded in 2013.
	The assumptions used in the determination of the fair value of the options granted are provided in the following table:
	Assumptions		Apr-11				Apr-12				Aug-12
			Options				Options				Options
	Expected volatility rate			61.53	%			41	%			43.38	%
	Expected dividend yield			3.14	%			3.77	%			3.4	%
	Risk-free interest rate			0.81	%			0.35	%			0.32	%
	Expected forfeiture rate			0	%			0	%			0	%
	Expected term in years			2.5				2.5				2.5
	The volatility rate for the options granted in 2012 is 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 for the options granted in 2011 was derived from the historical stock price volatility of a peer group of companies 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, 2013, 2012, and 2011, total share-based compensation expense (before tax) totaled $0, $281, and $502, respectively. In the years ended December 31, 2012 and 2011, this balance was recorded as an element of selling, general, and administrative expenses.
	The weighted average fair value of options granted in 2012 was $2.17 per option, in 2011 was $4.19 per option, and no options were granted in 2013.
	A summary of the activity of FutureFuel’s stock option awards for the period beginning January 1, 2011 and ending December 31, 2013 is presented below.

	The weighted average remaining contractual life of all exercisable options is 2.30 years.
	The aggregate intrinsic values of total options outstanding and total options exercisable at December 31, 2013 and 2012 are $741 and $154, respectively. Intrinsic value is the amount by which the last trade price of the common stock closest to December 31, 2013 and December 31, 2012, respectively, exceeded the exercise price of the options granted.
	No shares of stock were awarded in 2013, but 30,000 stock options were exercised during the year. In 2013, FutureFuel realized gross proceeds from stock option exercises of $0 and realized a net tax benefit of $40. All of the options exercised in 2013 were exercised on a cashless basis and resulted in 21,613 shares of FutureFuel’s common stock being returned to FutureFuel by the stock option holder. Such shares were returned to satisfy payment of the exercise price along with minimum tax requirements. Such minimum tax requirements totaled $45.
	No shares of stock were awarded in 2012, but 441,277 stock options were exercised that year.

	As a result of recently issued technical guidance from the U.S. Internal Revenue Service, FutureFuel has changed its position related to this benefit to exclude it from taxable income for the years 2010 through the current year. 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, with $7,755 related to the years 2010 through 2012, and $3,878 related to the current year. . This benefit is not expected to recur in the future as the $1 biodiesel blenders' tax credit expired on December 31, 2013 and has not been renewed. This change reduced taxable income in each year between 2010 and 2012 and also impacts fiscal 2013. This change is expected to result in a refund from the U.S. Internal Revenue Service for a portion of the amount Futurefuel has paid for income taxes in prior year.
	FutureFuel’s unrecognized tax benefits totaled $1,718 and $0 at December 31, 2013 and 2012, respectively.

	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 a balance of $0 at December 31, 2013 and December 31, 2012 for interest or tax penalties.
FutureFuel and its subsidiaries file tax returns in the U.S. federal jurisdiction and with various state jurisdictions. FutureFuel is subject to U.S., state, and local examinations by tax authorities from 2010 forward. FutureFuel Chemical is subject to the effects of tax examinations that may impact the carry-over basis of its assets and liabilities.

	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 $20,391at December 31, 2013, with $6,869 classified as a current liability and $13,522 classified as a noncurrent liability. Deferred revenue totaled $33,755 at December 31, 2012, with $6,071 classified as a current liability and $27,684 classified as a noncurrent liability.
	The following table summarizes FutureFuel’s deferred revenue activity:

	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 $2,521 at December 31, 2013 and 2012.

	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 (“Securities Act”), as amended, 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 may 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 aggregrate gross proceeds of approximately $37,247, resulting in net proceeds of approximately $36,127 after deducting commissions and fees.

	Biodiesel, petrodiesel and blends
	FutureFuel enters into agreements to buy and sell biofuels (biodiesel, petrodiesel, biodiesel/petrodiesel blends, RINs, and biodiesel production byproducts) and other petroleum products such as gasoline with an affiliate from time to time. Such agreements are priced at the then current market price of the product, as determined from bids from other customers and/or market pricing services. 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 thruput 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, thruput, and other customary terminalling charges.
	Commodity trading advisory fees
	FutureFuel entered into a commodity trading advisory agreement with an affiliate. Pursuant to the terms of this agreement, the affiliate provides advice to FutureFuel concerning the purchase, sale, exchange, conversion, and/or hedging of commodities as FutureFuel may request from time to time.
	Travel and administrative services
	FutureFuel reimburses an affiliate for travel and other administrative services incurred on its behalf. Such reimbursement is performed at cost with the affiliate realizing no profit on the transaction.
	Railcar sublease agreement
	FutureFuel entered into a railcar sublease agreement with an affiliate. Pursuant to the terms of this sublease, FutureFuel leased from the affiliate railcars upon the same terms, conditions, and price the affiliate leased the railcars. Lease terms for individual railcars began upon delivery of the railcars. Forty railcars were received through December 31, 2009. From the onset of this lease, FutureFuel paid lease charges directly to the entity leasing the railcars to the affiliate, as opposed to paying the affiliate itself. Hence, no related party expense is reflected in the above table, although the affiliate has essentially been guaranteeing FutureFuel’s obligations to the lessor. In September 2009, the master lease was modified such that the affiliate was removed and FutureFuel leases the railcars directly, with no guarantee remaining on the part of the affiliate. Expenses related to this lease were $315 for December 31, 2013 and $331 for each of the years ended December 31, 2012 and 2011.

Segment Reporting [Abstract]	'
Segment Reporting Disclosure [Text Block]	'
	20)           Segment information
	FutureFuel has two reportable segments organized along 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 comprises 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 and through distribution facilities available at a leased oil storage facility near Little Rock, Arkansas at negotiated prices.
	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, 2013, 2012, and 2011 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
					Countries
	31-Dec-13	$	430,096		$	14,823		$	444,919
	31-Dec-12	$	338,307		$	13,522		$	351,829
	31-Dec-11	$	295,780		$	14,105		$	309,885
	For the years ended December 31, 2013, 2012, and 2011, revenues from Mexico accounted for 3%, 3%, and 4%, respectively, of total revenues. Other than Mexico, revenues from a single foreign country during 2013, 2012, or 2011 did not exceed 1% of total revenues.
	Summary of business by segment
		2013			2012			2011
	Revenues
	Chemicals	$	161,501		$	160,450		$	168,237
	Biofuels		283,418			191,379			141,648
	Total revenues	$	444,919		$	351,829		$	309,885

	Chemicals	$	54,708		$	48,661		$	42,685

	Interest and other income/(expense)		1,222			4,012			(2,335	)
	Provision for income taxes		(23,317	)		(20,576	)		(18,266	)
	Net income	$	74,034		$	34,304		$	34,509
	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, 2013 were favorably impacted by the receipt of approximately $886 awarded to FutureFuel under the United States Department of Agriculture Section 9005 – Advanced Biofuel Producers program in 2013. This award totaled $753 and $1,900 in 2012 and 2011, 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 a common pipeline carrier.

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.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]	'
	25)          Recently issued accounting standards
	In February 2013, the Financial Accounting Standards Board issued accounting guidance, given divergence in practice, covering loss contingencies that are joint and several liability arrangements for which the settlement amount is fixed and is not covered by other GAAP. Under the new requirements, an entity is to measure the obligation as the amount the entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the entity expects to pay on behalf of its co-obligors. This guidance is effective for reporting periods beginning after December 15, 2013. Futurefuel has concluded that this new guidance will not have a material impact on Futurefuels financial postion or results of operations.
	In April 2013, the Financial Accounting Standards Board issued clarifying guidance that requires financial statements to be prepared using the liquidation basis of accounting to present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation when liquidation is imminent. Liquidation is considered imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved and the likelihood is remote that the execution of the plan will be blocked by other parties or (b) a plan for liquidation is being imposed by other forces (i.e. involuntary bankruptcy). This guidance is effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013. FutureFuel has concluded that this new guidance will have no impact on FutureFuel’s financial position or results of operation.
	In July 2013, the Financial Accounting Standards Board issued amended accounting guidance to permit the use of the Fed Funds Effective Swap Rate as a U.S. benchmark interest rate for hedge accounting purposes. In addition, the update also removes the restriction on using different benchmark rates for similar hedges. This guidance is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. FutureFuel has concluded that this new guidance will not have an impact on FutureFuel’s financial position or results of operations.
	In July 2013, the Financial Accounting Standards Board issued amended accounting guidance, given divergence in practice that addresses the financial statement presentation of tax items eligible for netting. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. This guidance is effective prospectivly for reporting periods beginning after December 15, 2013. Retrospective application and early adoption is permitted. FutureFuel has concluded that this new guidance will not have an impact on FutureFuel’s financial positon or results of operation.

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. FutureFuel does not expect additional material to be produced or sold in 2014 under that agreement. Termination of this sales contract also may affect the terms of the grant received by FutureFuel from the U.S. Department of Energy related to construction of the equipment utilized to produce the intermediate anode powder. As a result of this 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 remains liable for the payment of a minimum take or pay quantity per the terms of the sales agreement through the termination date.

	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, 2013
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, FFC Grain, L.L.C., which was formed in 2009 to acquire a granary in Marianna, Arkansas, FutureFuel Warehouse Company, LLC, 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. Certain prior period amounts have been reclassified to conform to the current period presentation.
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 collectibility 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 bleach activator are made to a leading North American consumer products company. Sales of the bleach activator totaled $56,596 for the year ended December 31, 2013 and $60,710 for the year ended December 31, 2012. Additionally, all sales of a herbicide and certain other intermediates used in the production of this herbicide are made to one customer. Sales of this herbicide and its intermediates constituted less than 10% of consolidated revenues for the year ended December 31, 2013 and 2012. Sales of biodiesel to one customer totaled $135,273 for the year ended December 31, 2013 and $102,772 for the year ended December 31, 2012.
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 maintains inventories of biodiesel and utilizes various derivative instruments such as regulated futures and regulated options as an economic hedge to reduce the effects of fluctuations in the prices of biodiesel. These derivative instruments do not qualify for hedge accounting under the specific guidelines of ASC 815-20-25, Derivatives and Hedging, Hedging-General, Recognition. While management believes each of these instruments are entered into in order to effectively manage various market risks, none of the derivative instruments are designated and accounted for as hedges primarily as a result of the extensive record-keeping requirements.
	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.
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:
	Buildings and building equipment (years)	20	–	39
	Machinery and equipment (years)	3	–	33
	Transportation equipment (years)	5	–	33
	Other (years)	5	–	33
Goodwill and Intangible Assets, Policy [Policy Text Block]	'
	Customer relationships
	Customer relationships are recorded at acquisition cost and are amortized on a straight-line basis over their estimated useful lives of five years. FutureFuel reviews and evaluates the recoverability of the carrying amounts of its acquired customer contracts annually, or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	'
	Impairment of assets
	FutureFuel evaluates the carrying value of long-lived 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.
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 (“ASC 740”), clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC 740 provides that a tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. Income tax positions must meet a more-likely-than-not recognition threshold to be recognized. ASC 740 also provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.
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 warranties.
	Bill and hold transactions for 2013 and 2012 related to six specialty chemical customers, and five specialty chemical customers in 2011, 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 $44,047, $50,076, and $59,597 for the years ended December 31, 2013, 2012, and 2011, respectively.
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 2013 and 2011, the biodiesel tax incentive for blending biodiesel with petroleum diesel is netted from costs of goods sold. The biodiesel tax credit 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. The tax credit terminated on December 31, 2011. On January 3, 2013, the tax credit was retroactively reinstated for 2012 and extended through December 31, 2013 (see Note 3). This tax credit expired and has not been reinstated.
	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
	Basic earnings per share is computed by dividing net income (the numerator) by the weighted average number of outstanding shares (the denominator) for the period. Diluted earnings per share are calculated in accordance with the treasury stock method to determine the dilutive effect of warrants and options. The computation of diluted earnings per share includes the same numerator, but the denominator is increased to include the number of additional common shares from the exercise of warrants and options that would have been outstanding if potentially dilutive common shares had been issued.
Comprehensive Income, Policy [Policy Text Block]	'
	Comprehensive income
	Comprehensive income is comprised of net income and other comprehensive income (“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, 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, 2012, FutureFuel recorded other comprehensive income of $794, net of income taxes of $495, on these securities. For the year ended December 31, 2011, FutureFuel recorded other comprehensive income of $1,278, net of income taxes of $797, on these securities. For the year ended December 31, 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 $207, net of income taxes of $129. For the year ended December 31, 2011, FutureFuel reclassified a portion of its unrealized losses 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 $1,669, net of income taxes of $1,041. No such reclassification was made for the year ended December 31, 2012.
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 principals 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.
