Trump Tariff Tracker 2026
Every tariff action this year, sourced to the government proclamation or filing that set it, not to any single news summary.
Canada is where the tariff story is moving fastest right now. On 8 September the administration issued five proclamations at once: two adjusting which Canadian goods carry the existing 50% Section 338 duty (effective 15 September), and three converting that duty into an outright import ban on beer, wine, distilled spirits, whey, molasses, and motorcycles (effective 29 September). The same date also matters for pharmaceuticals: the 100% Section 232 duty on patented drugs and APIs, which took effect for large manufacturers on 31 July, extends to smaller ones on 29 September.
Everything since February traces back to one ruling. The Supreme Court struck down IEEPA tariffs 6-3 that month, and within hours the administration pivoted to Section 122, a 10% global surcharge that, by statute, could only last 150 days. It expired 24 July and was replaced the same moment by Section 301 tariffs on roughly 60 economies, which still stand alongside the Section 232 and Section 338 actions tracked here.

What changed
Newest first. Each entry links to its primary source.
- : Canada Section 338 product list modified
Rock salt and cement came off the 50% Section 338 list; all-terrain vehicles and additional dairy products were added, ahead of the outright import ban that takes effect on the remaining named categories on 29 September.
GHY International - Section 338 Canada tariff guidance - : Trump signs five proclamations escalating Section 338 action against Canada
Three proclamations impose an outright import ban on Canadian beer, wine, distilled spirits, whey, molasses, and motorcycles, effective 29 September; two more modify which goods carry the existing 50% duty, effective 15 September. The White House frames the escalation as a response to Canada's own new retaliatory tariffs on roughly $20 billion of US exports, including steel, dairy, and agricultural equipment. Goods already imported but not yet entered for consumption before 29 September stay at the 50% duty rather than the ban.
Troutman Pepper Locke - Section 338 escalation against Canada - : 50% Section 338 tariff on Canadian goods takes effect
The duty announced in the 20 July proclamation took effect on covered Canadian autos, alcoholic beverages, dairy, and the Annex II product list, stacking on top of whatever Section 232 tariffs already applied to the same goods.
- : Section 122 expires; Section 301 tariffs on ~60 economies take its place with no gap
The 10% global surcharge Trump imposed under Section 122 on 24 February ran out its statutory 150-day clock at 12:01 a.m. ET. Within the hour, USTR's Section 301 regime took effect at the same moment, a two-tier 10%/12.5% duty covering roughly 60 economies, about 99.4% of US imports by value.
Nakachi Eckhardt & Jacobson - Section 122 surcharge sunset - : Section 232 pharmaceutical tariff proclaimed: 100% on patented drugs and APIs
A tiered effective-date structure: 31 July 2026 for large manufacturers, 29 September 2026 for smaller ones. Companies with an MFN pricing agreement signed before 2 April and listed in Annex II are exempt outright; those with a later MFN agreement get a 0% Section 232 rate from 29 September 2026 through 20 January 2029. Generic drugs, biosimilars, and their ingredients are excluded entirely.
Crowell & Moring - Section 232 pharmaceutical tariffs - : Supreme Court strikes down IEEPA tariffs 6-3; Trump pivots within hours
The Court held IEEPA never authorized tariffs at all, every IEEPA-based tariff was unlawful from the start, and affected importers may be owed refunds. Trump responded the same day by imposing a 10% global surcharge under Section 122 and announcing Section 301 investigations that would later replace it.
