In the context of US export controls, US ITAR stands for the US International Traffic in Arms Regulations. These International Traffic in Arms Regulations are primarily administered by the Department of State’s Directorate of Defense Trade Controls (DDTC). The ITAR are a set of US regulations on the export and import of defense-related articles and services. The International Traffic in Arms Regulations implement the US Arms Export Control Act (AECA) and can be found in the US Code of Federal Regulations (CFR) – in Title 22 CFR § 120-130.
Items subject to control under the International Traffic in Arms Regulations are listed on the US Munitions List (USML) and include articles, services, and related technical data. The ITAR also include a specific section for space-related products, services, and technologies.
All manufacturers, exporters, and distributors of defense articles, related technical data, and defense services as defined by the ITAR are required to register with the DDTC. Anyone intending to export or temporarily import a defense article must obtain prior approval of the DDTCC unless they qualify for an exemption in line with the US ITAR.
