Registration Guidelines for Fuels and Fuel Additives

On this page:

The following guidelines apply to Fuel and Fuel Additive Registrations (FFARs) under Title 40 CFR Part 79 as authorized by the Clean Air Act.

Products that must be registered:

A fuel or fuel additive marketed solely for use off-road, such as non-road diesel or a fuel additive solely for use in marine engines.
An on-road fuel that is not gasoline or diesel, such as E85 or compressed natural gas.

Please note:

Certain fuels and fuel additives, whether or not they are subject to registration under the Clean Air Act, may be subject to requirements under the Toxic Substances Control Act (TSCA).
View information on the Toxic Substances Control Act (TSCA).

Registration at 40 CFR 79 is by manufacturer/company. It covers production of a registered fuel or fuel additive at all of the manufacturer’s facilities, even facilities acquired after registration. For example, a manufacturer of biodiesel may only have one facility at the time of registration. Later, the manufacturer may acquire a second facility to produce biodiesel. The biodiesel produced at the second facility would be covered by the registration. (Note: Fuel registration at 40 CFR 80 is by facility.)
The definition of a fuel manufacturer includes an importer.
The definition of an additive manufacturer includes an importer.

There are unique registration requirements for E15 fuel (a blend of 85% gasoline and 15% ethanol). Click this link or the tab above for more information: E15 fuel registration
