Supreme Court Tariff Ruling Favors China
China has emerged as the big winner from a new U.S. Supreme Court ruling that weakens the legal foundation for new trade barriers. The decision gives Beijing more leverage just weeks before Trump's planned visit to seek a trade truce. Legal experts suggest Trump's proposed new tariffs may now be illegal, though it's unlikely to deter his aggressive trade strategy.
The Supreme Court's 6-3 decision in *Learning Resources, Inc. v. Trump* found the president overstepped his authority by using the International Emergency Economic Powers Act (IEEPA) for broad tariffs. The majority opinion, written by Chief Justice John Roberts, affirmed that the power to tax—which includes levying tariffs—is constitutionally granted to Congress, not the executive branch. This ruling specifically invalidates the 10% "fentanyl" tariff and the 10% "reciprocal" tariff that had been applied to goods from China. Tariffs imposed under different laws, such as the Section 301 duties that make up the bulk of levies against China or the Section 232 tariffs on steel and aluminum, are not affected by this decision. Within hours, the administration responded by invoking a different law, Section 122 of the Trade Act of 1974. This was used to impose a new, temporary 15% global tariff on nearly all imports, effective February 24, 2026. The Section 122 authority has significant limitations: it allows the president to act for only 150 days to address a "balance-of-payments" deficit and caps tariffs at 15%. Any extension beyond the 150-day period requires explicit approval from Congress. For China, the new flat 15% tariff is lower than the previous combination of reciprocal and fentanyl-related levies, which totaled 20%. The overall U.S. trade-weighted average tariff is now estimated to be 13.2%, down from 15.3% before the ruling. The decision striking down the IEEPA tariffs has created a massive potential liability for the U.S. government. Importers who paid the now-invalidated duties may be entitled to refunds, with analysts estimating the total could be as high as $130 billion to $175 billion.
