U.S. export controls are laws and regulations that restrict the flow of certain materials, devices, and technical information outside of the U.S. or to foreign persons within the U.S. They are intended to provide national security, promote foreign policy objectives like anti-terrorism, and prevent weapons proliferation. The primary government agencies that administer export controls are the Departments of Commerce, State, and Treasury. There are three main sets of rules: the Export Administration Regulations, International Traffic in Arms Regulations, and Economic Sanctions Regulations.
