US Section 122 of Trade Act of 1974 Expires; Replacement Tariffs Push Effective Rate to 11.8%, China to 27.2%

The US Section 122 of the Trade Act of 1974 expired on July 24, 2026, prompting replacement tariffs under Sections 301, 232, and 338. New Section 301 forced-labor tariffs impose 12.5% and 10% additional duties on 60 and 14 economies respectively, covering over 99% of US imports. A separate Section 301 investigation on Brazil resulted in a 25% tariff on most Brazilian goods. Section 232 tariffs cover steel, aluminum, and other sectors. Section 338 was first used on July 20, imposing a 50% punitive tariff on Canadian imports of cars, parts, alcohol, clothing, and furniture. The US weighted average effective tariff rate fell to 8.3% after Section 122 expiry, then rose to 11.8% after new tariffs. China's average rate rose from 25.9% to 27.2%, and Canada's from 5.3% to 7.8%.

China's Ministry of Commerce announced on July 27, 2026, a ban on further shipments of dual-use materials to 14 EU companies, including German defense contractor Rheinmetall, Sindhauser Materials, and Italy's Rafat Group. The move retaliates against EU sanctions on 14 Chinese and Hong Kong firms over Russia's war in Ukraine. China has leveraged its dominance in rare earth mining and processing as a bargaining chip over the past 16 months, having imposed export restrictions on tungsten, antimony, gallium, germanium, and seven rare earth metals since late 2024.
