The United States Munitions List (USML) is a list of articles, services, and related technology designated as defense-related by the United States federal government. This designation is pursuant to sections 38 and 47(7) of the Arms Export Control Act (22 U.S.C. 2778 and 2794(7)). These articles fall under the export and temporary import jurisdiction of the Department of State.
The USML is found in Part 121 of Title 22, Foreign Relations, of the Code of Federal Regulations (CFR). The USML is amended by rules published in the Federal Register. Further information and clarification whether specific articles or services fall under the USML are periodically discussed in Defense Trade News published by the State Department's Bureau of Political-Military Affairs.
Any article, service, or related data found to be on the USML requires an export license (issued by the United States State Department) to be exported (given to a non-U.S. person). A "U.S. person" is a U.S. citizen or permanent resident who does not work for a foreign company, government, or NGO. Some license exceptions are available under specific circumstances.
Exports of all other products not covered by the USML are subject the export jurisdiction of the United States Department of Commerce, Bureau of Industry and Security (BIS). The first step in exporting a non-USML item under the BIS regulations is to identify the Export Control Classification Number (ECCN).
