The Supreme Court on Thursday struck down the legal basis for President Donald Trump’s sweeping global tariffs, forcing the federal government to halt their collection and throwing U.S. trade policy into immediate transition rather than resolution.
Within hours, the White House replaced them.
The administration issued a proclamation imposing a new 10% import duty on many foreign goods for 150 days beginning Feb. 24 — ensuring tariffs remain in place even as the court dismantled the previous ones. The rapid shift underscores that the ruling did not end the trade conflict, but instead changed how it must be carried out.
The court ruled the administration improperly relied on the International Emergency Economic Powers Act, a national-security sanctions law, to impose broad economic tariffs. A coalition of states challenged the move, arguing the statute does not authorize a president to impose sweeping import taxes. The justices agreed, ordering the emergency-based tariffs terminated.
Federal agencies must now stop collecting those duties, and businesses that paid them are expected to pursue refunds through further litigation.
But the decision did not eliminate presidential tariff authority entirely. It only barred using emergency powers as the justification.
The administration’s replacement policy relies instead on Section 122 of the Trade Act of 1974, which allows a president to impose temporary import surcharges to address serious balance-of-payments problems. In the proclamation, the White House argued the United States faces a large and persistent trade deficit and declining international investment position, and that a temporary import surcharge is necessary to stabilize the economy.
The new duty applies broadly but includes exemptions for categories such as certain energy products, pharmaceuticals, some vehicles, and goods covered by existing trade agreements. Unlike the struck-down tariffs, the measure is capped at 150 days unless Congress approves an extension.
The legal shift is significant. The previous tariffs were indefinite and largely unilateral; the replacement is temporary, tied to specific economic findings, and subject to congressional oversight and potential court review. The administration also directed trade officials to pursue additional investigations that could support longer-term tariffs under other statutes.
The ruling therefore moves the fight out of the realm of emergency executive power and into political and statutory channels. Lawmakers can now vote to extend, block or modify tariffs, and courts may eventually weigh whether the economic justification satisfies federal law.
For businesses and consumers, the immediate effect is uncertainty rather than relief. The tariffs that existed under emergency authority are gone, but a narrower set has taken their place — and the future of broader trade restrictions now depends on Congress and ongoing legal challenges rather than a single presidential order.
