Pursuant to 18 U.S.C. 841(d) and 27 CFR 555.23, ATF must publish and revise at least annually in the Federal Register a list of explosives determined to be within the coverage of 18 U.S.C. 841 et seq. The list covers not only explosives, but also blasting agents and detonators, all of which are defined as explosive materials in 18 U.S.C. 841(c). ATF has not removed any listing since its last publication of the List of Explosive materials; however, for the purpose of officially clarifying that “pyrotechnic fuses” meet the statutory definition of explosive materials, ATF has added “pyrotechnic fuses” to the List of Explosive Materials.
