Federal trade court declares Trump's 10% global tariffs unlawful

Tariffs are back in court again — but this time the fight is over a narrower fallback tool, not the big emergency-powers tariffs that blew up last year. On May 7, the U.S. Court of International Trade ruled that President Trump’s 10% global tariff was unlawful because the statute he used, Section 122 of the Trade Act of 1974, only allows temporary action for 150 days. The administration had kept the tariff going past that limit. So the court told Customs to stop collecting it from the plaintiffs in the case. ### What tariff are we talking about? This is the across-the-board 10% tariff Trump imposed on most imports after the Supreme Court knocked out his broader “Liberation Day” tariff program in February 2026. That earlier strategy leaned on emergency powers. This one leaned on Section 122 — an older trade law that gives presidents a short-term way to respond to balance-of-payments problems. Basically, the White House tried a smaller legal doorway after the big one got shut. (jdsupra.com) ### Why did the court say it was illegal? Because Section 122 is temporary by design. The law lets a president impose a surcharge of up to 15% or use quotas, but only for 150 days unless Congress steps in with something more permanent. The trade court said Trump’s 10% tariff ran past that clock. That made the tariff unlawful under the very statute the administration chose. This was not the judges saying presidents can never use Section 122 — it was the judges saying this use lasted too long. (nbcnews.com) ### Who actually won the case? The plaintiffs were two importers and Washington state. And that matters because the relief was narrow. The court did not erase the tariff for every importer in America in one stroke. It blocked collection as to the parties before it. So this was a real loss for the administration, but not an instant nationwide shutdown of the tariff. (jdsupra.com) ### Why is this a big deal anyway? Because this 10% tariff was supposed to be the legally safer backup plan. Trump’s team had already lost a major fight over tariffs imposed under the International Emergency Economic Powers Act, or IEEPA. In May 2025, the Court of International Trade ruled those sweeping tariffs unlawful, and the Federal Circuit later agreed in part that IEEPA did not give the president the kind of tariff power he claimed. So the administration moved to a narrower statute. (jdsupra.com) Now that statute is in trouble too. ### Does the tariff disappear now? Not necessarily for everyone, and not finally. The administration has said it will appeal. That means the next fight is over whether the ruling gets stayed and how broadly it applies while appeals play out. The earlier IEEPA tariff case shows the pattern — the government lost at the trade court, then kept the fight alive on appeal. So importers may get legal momentum here without getting immediate certainty. (cit.uscourts.gov) ### Why does timing matter? Because this lands just before Trump’s planned Beijing talks. Tariffs are not just taxes at the border — they are bargaining chips. A court ruling that says one of the president’s newer tariff tools is unlawful weakens the threat behind any “we can always raise duties” negotiating posture. Even if the administration appeals, counterparties can see the legal limits getting tighter. (cafc.uscourts.gov) ### What is the real takeaway? The real story is not just one 10% tariff. It is that courts keep telling Trump he cannot invent broad tariff power out of statutes Congress wrote more narrowly. First the emergency route got cut back. Now the temporary fallback route has hit its own limit. The bottom line is simple — if the White House wants durable global tariffs, it may need Congress, not just creative lawyering. (nytimes.com)
