Revenue from Contract with Customer [Text Block]	3 ) REVENUE RECOGNITION FutureFuel recognizes revenue when performance obligations of the customer contract are satisfied. FutureFuel sells to customers through master sales agreements or standalone purchase orders. The majority of FutureFuel's terms of sale have a single performance obligation to transfer products.

For certain contracts, this occurs upon delivery of the material to a FutureFuel storage location, ready for customer pickup and separated from other FutureFuel inventory. Revenue is measured as the amount of consideration FutureFuel expects to receive in exchange for transferring products and is generally based upon a negotiated price.
