If you buy, sell, or ship anything that crosses a US border, July 24 should be circled in red on your calendar. This page keeps the whole US tariff picture in one place — what's actually in force today, what legally dies this month, and what's being lined up to replace it. We update it as the picture changes; the "Updated" date at the top tells you how fresh it is. * How we got here, in fast-forward: on February 20, 2026, the Supreme Court ruled in Learning Resources v. Trump that IEEPA — the emergency-powers law behind the sweeping 2025 tariffs — does not let a president impose tariffs at all. The White House switched laws the same day, invoking Section 122 of the Trade Act of 1974 to slap a 10% surcharge on imports from nearly every country, effective February 24, 2026. * Section 122 came with a catch no executive order can lawyer around: a hard 150-day limit written into the statute. Day 150 is July 24, 2026. At 12:01 a.m. EDT that morning, the 10% global tariff terminates by operation of law. Only Congress can extend it — and Congress has shown no appetite; the trade bill with actual momentum, the Reclaim Trade Powers Act, pulls in the opposite direction. * What's actually in effect right now (as of July 10, 2026): - Most countries: the 10% global surcharge (Section 122) — expires July 24. - European Union: 15% on most goods under the US–EU trade deal, with EU autos capped at 15% instead of the 25% everyone else pays. - China: roughly 35% in combined duties above the normal MFN rate on most goods, and well over 100% on certain strategic products — legacy Section 301 duties that survive July 24 untouched. - Canada & Mexico: goods that qualify under USMCA rules of origin keep preferential (often zero) rates — but autos and auto parts pay the 25% Section 232 tariff regardless. - Steel, aluminum, copper: 25–50% under Section 232, with no expiration date. * The replacement is taking shape in plain sight. USTR ran public hearings from July 7 to July 9 on its Section 301 investigations into 60 economies over forced-labor enforcement, with proposed duties of 10–12.5% — the 10% tier aimed at countries USTR says ban forced-labor imports but don't enforce the ban, a list that includes Canada, Mexico, the EU, Indonesia, Ecuador and Pakistan. The timing is not subtle: USTR faces a roughly July 20 completion deadline, landing days before Section 122 dies. And unlike Section 122, Section 301 has no rate cap and no time limit. * There's also a court fight running underneath all of this. In May, the US Court of International Trade struck down the Section 122 tariffs — but as the trade bar itself put it, the ruling's "fate is uncertain and practical impact is limited," and the duties have kept being collected while the appeal plays out. Meanwhile, importers are chasing refunds on the IEEPA tariffs the Supreme Court already killed. * What happens if July 24 arrives and the Section 301 replacement isn't ready? Imports from most countries revert to plain MFN rates plus the surviving sector tariffs — which would make most imported goods modestly cheaper on paper, at least until the next proclamation drops. That's the scenario every importer, and every White House trade lawyer, is now racing against.
