Section 301

Section 301 is a provision of the U.S. Trade Act of 1974 that lets the U.S. Trade Representative investigate foreign trade practices and impose unilateral remedies, such as additional tariffs, to address actions considered unfair to U.S. commerce. For example, Section 301 investigations resulted in tariffs on a broad range of Chinese imports in 2018-2019, prompting importers to adjust sourcing, pricing, or seek tariff exclusions to reduce the duty impact.
