Section 301 of the Trade Act of 1974 permits the United States Trade Representative (USTR) to investigate and impose sanctions on countries whose trade practices are found to be unfair to U.S. interests. It reaches beyond the General Agreement on Tariffs and Trade (GATT), to give the United States unilateral power to penalize countries that threaten American interests. Section 301 can be used to enforce United States rights under multilateral and bilateral trade agreements, as well as to remedy unreasonable, unjustifiable or discriminatory foreign trade practices that restrict or burden U.S. trade. It contains both mandatory and discretionary provisions and specific timetables for action by the USTR.
