"The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) published a notice in the Federal Register September 27 containing a list of 238 explosive materials that are subject to Federal law and implementing regulations. The annual list is comprehensive but not all-inclusive. Therefore, an explosive material may not be on the list but still may be within the coverage of the law if it meets the statutory definitions. The list covers not only explosives, but also blasting agents and detonators, all of which are defined as explosive materials in the United States Code chapter regulating the importation, manufacture, distribution, receipt, and storage of explosive materials. Some of the explosives on the list include dynamite, black powder, pellet powder, initiating explosives, pyrotechnic compositions, safety fuses, squibs, detonating cord, igniter cord, and igniters. The 2006 list contains no new terms, deletions, or revisions since the publication of the 2005 list."
