Classification 41: Explosives (Obsolete)

This classification was established in 1924 to cover investigations of violations of the Federal Explosives Act, which regulated the manufacture, sale, possession, and interstate transportation of explosives. In December 1941 the Act was amended to establish a licensing system administered by the Interior Department. When the wartime licensing provisions were cancelled in October 1945, the FBI suspended investigations relating to the Act. In 1958 the classification was declared obsolete.

The following records under Classification 41: Explosives (Obsolete) are not yet described in NARA's online catalog. Please contact NARA's Special Access Program at specialaccess_FOIA@nara.gov with your reference request.
