Tariffs
During his second term as president, Donald Trump has announced a range of new tariffs on goods imported into the US.
As of August 2026, US imports are subject to a complex combination of broad country-based tariffs and separate sector-specific measures. The precise duty depends on factors including the product’s classification and origin, and any applicable exemption, quota or trade arrangement.
Since 24 July 2026, a range of Section 301 tariffs have been in force, including forced-labour-related duties of 10% or 12.5% on goods from 60 economies. Separate tariffs imposed under Section 232 of the Trade Expansion Act of 1962 also remain in force, applying to various products including steel, aluminium, and lumber.
Meanwhile, certain Canadian goods are subject to 50% Section 338 tariffs.
The present regime follows a turbulent period of tariff changes. During 2025, President Trump imposed extensive country-based tariffs under the International Emergency Economic Powers Act (IEEPA). However, on 20 February 2026 the US Supreme Court ruled that the IEEPA tariffs were illegal, and they were removed from tariff schedules from 24 February. A temporary 10% global tariff imposed under Section 122 then applied for 150 days, until it was succeeded on 24 July by the current Section 301 measures.
It is important to note that tariffs are applied based on country of origin (not the country of dispatch), and that — as of 29 August 2025 — the $800 de minimis threshold for commercial shipments no longer applies.
