The Arms Export Control Act requires that all manufacturers, exporters, temporary importers, and brokers of defense articles (including technical data) as defined on the United States Munitions List (ITAR part 121) and furnishers of defense services are required to register with the Directorate of Defense Trade Controls (DDTC) as described in ITAR part 122. It is primarily a means to provide the U.S. Government with necessary information on who is involved in certain ITAR (International Traffic in Arms Regulations) controlled activities and does not confer any export or temporary import rights or privileges.
