The International Traffic in Arms Regulations (ITAR)—administered by the U.S. Department of State, Directorate of Defense Trade Controls (DDTC)—is a set of U.S. regulations (22 C.F.R. Parts 120-130) that control defense and space-related items, and data and services related to such items. These include even the most minor components, and can apply to related technical data and services even if no physical exports are taking place.
What is controlled under ITAR?
A DDTC license/authorization (or a written ITAR exemption) is always required to export, re-export or re-transfer a defense article, associated technical data or defense services to foreign destinations, as well as to provide defense services or technical data to a foreign person in the U.S. This includes drawings that are sent overseas for production of components and parts that are sent out of the U.S. for machining or manufacturing.
