Section 301 of the Trade Act of 1974
Section 301 authorizes the Office of the U.S. Trade Representative to respond to foreign acts, policies and practices it finds unfair. For years the label meant one thing, the China tariffs first imposed in 2018. In 2026 it means several. USTR has used the same authority to impose additional duties tied to forced labor across dozens of economies, a country-specific action against Brazil, and a separate action on China's maritime and shipbuilding dominance.
What unites the tariff actions is how the duty is charged: an additional ad valorem duty stacked on top of the ordinary rate at importation. Unlike the IEEPA tariffs, which are not drawback eligible, and unlike Section 232, which limits recovery to manufacturing drawback, no Section 301 duty measure bars drawback. When the duty-paid import, or a qualifying substitute, is exported or destroyed, the claimant recovers 99% of the duties paid under 19 U.S.C. 1313, the Section 301 duty included.
