Section 301 Additional Duties

Section 301 of the Trade Act of 1974 allows the US to impose additional tariffs or restrictions on imports from countries that violate trade agreements or engage in unfair practices. These duties are implemented in the HTS under Chapter 99 and apply by country of origin (e.g. certain products from China).

Base HTS rates still apply; Section 301 adds an extra duty on top. Use our tariff calculator or GET /api/v1/tariffs/resolve with hts and origin to see base tariffs and applicable Section 301 measures together.
