Spare parts, components, and subassemblies for military platforms — including parts for aircraft, vehicles, weapons systems, and electronics — are captured in this end-use category and are broadly subject to ITAR or EAR controls depending on the parent system's classification. Parts jurisdiction often mirrors that of the end item, meaning a component for an ITAR-controlled weapons system is itself ITAR-controlled even if the part appears commercially available. This creates significant compliance complexity for dual-use suppliers whose parts serve both military and commercial customers. Exporters must maintain robust records linking each part to its authorized end-use and end-user, as parts diversion is a primary enforcement focus of DDTC and the Commerce Department's Bureau of Industry and Security (BIS).
