The United States’ temporary 10 percent global tariff, imposed after the Supreme Court struck down the administration’s earlier trade architecture, expires on Friday. In its place, Washington is preparing to announce a new, permanent tariff regime on roughly 60 trading partners, anchored in findings on forced labour. The shift moves the legal basis from a short-term balance-of-payments provision to Section 301 of the Trade Act, allowing durable duties that cover the vast majority of US imports. The immediate effect is a bifurcated rate structure: a 10 percent levy on economies that have laws against forced-labour goods but are deemed to enforce them insufficiently, and a 12.5 percent levy on those with no such laws at all.

The mechanism flows from investigations by the Office of the US Trade Representative, which concluded that over 40 major economies—including China, India, and Japan—lack prohibitions on importing goods produced with forced labour, warranting the higher rate. Partners such as the European Union, Canada, Mexico, Taiwan, and the United Kingdom, which have legislation but are judged by Washington to fall short on enforcement, face the 10 percent tier. The same rate would apply to the UK, whose ban is considered partial. The new duties are designed to take effect before the temporary levy lapses, avoiding a window of duty-free access. USTR Jamieson Greer signalled that action is imminent, stating that the measures will cover the majority of US trade.

Viewed from Brussels, the forced-labour justification is “unjustified,” the EU has said, setting the stage for renewed transatlantic friction. In Ottawa, the new 10 percent tariff compounds pressure from a separate 50 percent levy on many Canadian goods, announced Monday and effective in 30 days, which Washington describes as a response to discriminatory treatment of US products. Prime Minister Mark Carney said Canada is examining “all options” and agreed with President Trump to intensify discussions in the coming weeks, though no trip to Washington has been confirmed. Brazil, meanwhile, faces a 25 percent tariff on a range of products from Wednesday over alleged unfair trade practices that Washington says reduced US market access. Beef, coffee, and certain aircraft parts are exempt, but the American Chamber of Commerce for Brazil warns the measure affects more than $11 billion in exports and places the country among those with the most restrictive conditions for US market entry. Argentina is also expected to be included in the new forced-labour tariff list, though its rate has not been specified.

The next factual milestone is the formal announcement of the permanent forced-labour tariffs, expected before Friday’s expiry. USTR Greer travels to Mexico for USMCA review talks, while negotiations with Canada proceed at a slower pace. The separate 25 percent Brazil tariff takes effect Wednesday, and the 50 percent Canada tariff on August 19. Whether these moves trigger a cycle of retaliation, as some trade lawyers in Washington warn, will depend on the responses from affected capitals in the days immediately following the announcement.
