The purpose of this open letter is to provide guidance to federally licensed firearms importers and registered importers of U.S. Munitions Import List Articles and clarification on the importability of firearms barrels under 18 U.S.C § 925(d)(3).

The Bureau of Alcohol, Tobacco, Firearms and Explosives (“ATF”) is issuing this open letter to assist Federal Firearms Licensees (“FFLs”) in understanding their obligations when they choose to provide firearm storage services to their customers and the public. 

The purpose of this letter is to provide all federal explosives licensees and permittees guidance on the safe storage of explosive materials. Electronic nicotine delivery systems, or other similar devices, are electronic devices that, through an aerosolized solution, deliver nicotine, flavor, and/or other substances (including non-tobacco products) to the user inhaling from the device. ATF has determined that electronic nicotine delivery systems are spark producing devices. Therefore, they cannot be brought into or within 50 feet of any outdoor explosives storage magazine or within any room containing an indoor magazine.

The purpose of this open letter is to notify all persons that ATF has rescinded special explosive device exemptions for certain consumer-style grenades (e.g. flashbang grenades, smoke grenades). As a result, these explosive devices are no longer exempt from the provisions of the Federal explosives regulations at 27 CFR, Part 555 – Commerce in Explosives.
