US Tariffs on Other Base Metals from United Kingdom — 10% (2026)

Among US trading partners for other base metals, United Kingdom plays a notable role, with approximately $138B in total bilateral trade.

As of March 2026, other base metals imports from United Kingdom 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.

Other Base Metals (HTS Chapter 81) carry an average MFN duty rate of 3.5% in addition to the Section 122 tariff. No additional Section 232 or Section 301 surcharges apply to most products in this category from United Kingdom.

Key products in HTS Chapter 81 imported from United Kingdom include Tungsten wire and rods, Titanium bars, Magnesium ingots, Cobalt, Molybdenum, and Tantalum capacitors.
