Regulations for Alcohol, Tobacco, Firearms and Explosives

Code of Federal Regulations

ATF regulations are published as Title 27, Chapter II, Code of Federal Regulations (CFR) by the Government Printing Office. Consult the official legal version of 27 CFR (updated April 1 of each year) and any more recent final/interim rules to learn the requirements that apply to you.

The Electronic Code of Federal Regulations (e-CFR) is a currently updated version of the CFR. It is not an official legal edition of the CFR. The e-CFR is an editorial compilation of CFR material and Federal Register amendments produced by the National Archives and Records Administration’s Office of the Federal Register (OFR) and the Government Printing Office. The OFR updates the material in the e-CFR on a daily basis.

ATF Electronic Regulations

ATF has developed an electronic regulations website at designed to make regulations easier to read, understand, navigate and search. This new interactive format provides additional information that clarifies regulations by providing quick links to definitions, regulatory history, and future proposed changes to the regulations.
