The International Traffic in Arms Regulations (ITAR) is a set of U.S. government rules that control the export and import of defense-related articles and services. ITAR aims to ensure that military technology and sensitive information do not fall into the hands of unauthorized foreign entities. This regulation applies to various items, including weapons, military vehicles, and related technical data. Under ITAR, companies and individuals involved in the defense industry must register with the U.S. Department of State and obtain licenses for exporting controlled items. Violations of ITAR can result in severe penalties, including fines and imprisonment, emphasizing the importance of compliance for entities like defense contractors and manufacturers.
