Section 301 Tariffs Replace Expiring Global Duties

Section 301 tariffs take effect at 12:01 a.m. ET July 24, replacing the expiring global tariff with a two-tier package targeting countries accused of weak labor enforcement. The new duties aim to reduce legal vulnerability while maintaining higher import levies.

Section 301 Tariff Details and Coverage

The administration is imposing these tariffs under Section 301 of the Trade Act of 1974 after a months-long investigation by the U.S. Trade Representative (USTR) into alleged forced-labor practices across about 60 economies. The package establishes two ad valorem rates—10% and 12.5%—applied broadly to imports from those countries, with an Annex A exemption list largely mirroring carve-outs from the prior temporary global tariff. Products already subject to other tariff regimes, such as Section 232 metals tariffs, are excluded. The targeted partners account for roughly 99% of U.S. imports.

Countries judged to have adequate anti-forced-labor laws and enforcement fall into the lower 10% tier. This group includes Canada, Mexico, the European Union, the United Kingdom, Taiwan, Indonesia, Pakistan, and Ecuador. Nations assessed as falling short face the higher 12.5% duty; this list includes China, India, Japan, and more than 40 other economies.

The new tariffs take effect as the Section 122 global tariff expires, with a short transit exemption allowing goods already en route to enter duty-free until 12:01 a.m. ET July 28.

Legal Context and Tariff Layering

The Supreme Court struck down the administration’s earlier emergency-powers global tariff, ruling that the president lacked clear congressional authorization to impose sweeping import duties under the International Emergency Economic Powers Act (IEEPA). Following that decision, the administration shifted to explicit statutory authorities, primarily Section 301, alongside Section 232, Section 122, and a rarely used provision of the Tariff Act of 1930, to rebuild its tariff program.

Legal analysts note that the forced-labor Section 301 package is structured around detailed statutory investigations and findings to create a stronger administrative record and reduce vulnerability to judicial challenges.

These forced-labor duties add to a complex tariff landscape. USTR recently announced 25% Section 301 tariffs on certain Brazilian goods effective July 22, with exemptions for products like beef and coffee. Presidential proclamations under the Tariff Act of 1930 impose 50% tariffs on a range of Canadian imports, including motor vehicles and dairy, effective August 19. A June 1 proclamation adjusted Section 232 metals tariffs, creating tiered rates up to 50% depending on product and origin, with the regime running through December 31, 2027.

Separately, an executive order following a Section 232 pharmaceutical review established a 100% baseline tariff on imported patented pharmaceuticals and related ingredients, with phased effective dates beginning July 31 and September 29, 2026. The administration also plans a future program targeting generic drugs, starting at 100% in August 2028 and rising to 200% in 2029.

USTR materials indicate that rate assignments and the exemptions list may be revised if countries improve forced-labor laws or enforcement. Section 301 duties can remain in place until modified or terminated by the trade representative, with no automatic sunset, suggesting potential for durable trade frictions as these measures layer on top of existing surcharges.
