International Traffic in Arms Regulations (ITAR) controls the export and import of defense-related articles and services on the United States Munitions List (USML). . The regulations are administered by the U.S. Department of State's Directorate of Defense Trade Controls (DDTC).
As an important U.S. export control law, the ITAR affects the manufacture, sale, and distribution of technology, and works to prevent the disclosure or transfer of sensitive information to a foreign national. Any CM that produces defense-related products must be ITAR compliant.
