Every extraordinary tariff action since March 2025, by country and sector, with its legal status and primary source. The headline rates up top; the full ledger below, filterable and cited.
The desk's read
This is the Infinity Loop in one ledger, the run of proclamations, exemptions, and pauses that replaced coherent trade policy since March 2025. The headline misses who pays: nearly 90% of the 2025 tariffs' burden fell on U.S. firms and consumers, not foreign exporters. The courts have since caught up. The IEEPA tariffs were struck down and ended in February 2026, and the Section 122 surcharge that replaced them was invalidated and expired by July. The response was not restraint but redirection, into Section 232 metals and autos, a new Section 301 forced-labor regime reaching 60 economies, and Section 338 tariffs on Canada. The authority keeps changing; the uncertainty does not.
Watch the USMCA lines most closely, because a tariff that reaches goods the treaty already covers, now including 50% Section 338 duties on Canadian autos, alcohol, and dairy regardless of origin, cuts against the agreement all three countries signed.

Primary legal documents
Primary sources: U.S. Federal Register proclamations, executive orders, and White House actions (IEEPA, Section 122, Section 232, Section 301, Section 338), cited per action with docket numbers.
Coverage begins March 2025, the start of the extraordinary-tariff period, and is maintained as new actions are published. The IEEPA tariffs were terminated in February 2026 and the Section 122 surcharge expired in July 2026; both remain in the ledger, marked terminated.
USMCA-compliant goods from Mexico and Canada are largely exempt from the metals and reciprocal measures, with one major exception: the Section 338 duties on Canada apply regardless of USMCA origin.
