Fuel Alcohol

Fuel alcohol is distilled spirits that have been made unfit for beverage use at an alcohol fuel plant (AFP) as provided in Subpart X of 27 CFR part 19. An alcohol fuel plant is a special type of distilled spirits plant authorized under 26 U.S.C. 5181 and established solely for producing, processing, storing and using, or distributing distilled spirits to be used exclusively for fuel use.

  • The distilled spirits may not be derived from petroleum, natural gas, or coal and the distilled spirits must be rendered unfit for beverage use before withdrawal (including exportation) from an AFP.
  • The distilled spirits may be used on AFP premises without denaturation for fuel purposes only and may be transferred in bond between AFP and distilled spirits premises without denaturation.
  • There are materials authorized in the regulations and on our website at the alcohol fuel rulings page for making the distilled spirits unfit for beverage use.
  • Formula approval on TTB Form 5150.19 is not required to make fuel alcohol.
  • Only TTB registered AFPs can make fuel alcohol.

To every 100 gallons of alcohol add:

  • 2 gallons or more of gasoline; automotive gasoline; rubber hydrocarbon solvent; kerosene; deodorized kerosene; methyl isobutyl ketone (MIBK); mixed isomers of nitropropane; natural gasoline; heptane; ethyl tertiary butyl ether (ETBE); raffinate; naphtha; high octane denaturant blend; straight run gasoline; or any combination of these; or
  • 2 gallons of isopropyl alcohol plus 1/8 oz. denatonium benzoate; or
  • 5 gallons or more of toluene
