US Tariffs on Copper from Mexico — 60% (2026)

Among US trading partners for copper, Mexico plays a notable role, with approximately $779B in total bilateral trade.

As of March 2026, copper imports from Mexico face a base tariff rate of 10% under Section 122 of the Trade Act of 1974. This rate replaced the previous IEEPA reciprocal tariff following the Supreme Court's 6-3 ruling in V.O.S. Selections Inc. v. United States on February 20, 2026.

Under the Trade Act of 1974, Section 122 tariffs are limited to 150 days. The current 10% rate expires around July 24, 2026. Congressional action would be required to extend these tariffs beyond that date.

Products in this chapter may be subject to Section 232 tariffs of 50% on steel and aluminum items, which were doubled in June 2025 and remain unaffected by the SCOTUS ruling. When applicable, the combined rate reaches 60%.

Mexico is party to the USMCA, which may provide preferential or duty-free access for qualifying copper. Importers should verify rules of origin requirements to take advantage of preferential rates.

Key products in HTS Chapter 74 imported from Mexico include Copper wire, Copper cathodes, Brass fittings, Copper pipes and tubes, Copper foil, and Bronze alloys.
