As SCOTUS Strikes Down Emergency Tariffs, Trump Signals New Import Duties

The U.S. Supreme Court’s 6–3 decision to strike down a significant portion of President Trump’s tariffs regime has quickly given way to a new phase of legal and commercial uncertainty, as the administration moves to replace the invalidated measures with temporary tariffs under a different statute. The rapid policy pivot highlights the limited practical relief for businesses, with companies across industries now confronting a shifting tariff framework rather than a clear rollback of trade pressure.

Writing for the majority in the February 20 opinion, Chief Justice Roberts concluded that the 1977 International Emergency Economic Powers Act (“IEEPA”) does not authorize the president to impose tariffs, rejecting the administration’s attempt to rely on emergency powers to levy broad import duties. The Court emphasized that while the statute permits the president to “regulate” imports during a national emergency, it does not explicitly authorize tariffs – a gap that proved decisive. “The President asserts the extraordinary power to unilaterally impose tariffs of unlimited amount, duration, and scope,” Roberts wrote, adding that such authority requires clear congressional authorization. Justice Kavanaugh wrote a dissenting opinion, which was joined by Justices Thomas and Alito.

Any immediate relief for brands and manufacturers, however, has been tempered by the administration’s rapid pivot. President Trump initially announced a replacement 10% tariff on all imported goods but subsequently signaled that the rate would be increased to 15% under Section 122 of the Trade Act of 1974 – a rarely used provision that allows temporary import restrictions to remain in place for roughly five months before congressional approval is required.

The shift highlights the administration’s determination to preserve broad tariff leverage despite the Court’s rebuke, while raising fresh questions about timing, legality, and the likelihood of additional legal challenges. It also introduces new friction for countries and companies that had begun adjusting expectations around a 10% tariff framework.

Ripple Effects for Retail

For the retail industry, the combined impact of the Court’s ruling and the administration’s response is less a rollback than a reshuffling of exposure. The now-invalidated emergency-based tariffs, which reshaped sourcing strategies  across apparel, footwear, personal luxury goods, automotive manufacturing, and semiconductor-dependent electronics, including sweeping “reciprocal” tariffs and duties tied to fentanyl enforcement concerns involving Canada, China, and Mexico.

While tariffs on steel and aluminum imposed under separate statutes remain intact, more than $130 billion in duties collected under the IEEPA framework are now subject to potential dispute, with hundreds of companies pursuing refund claims. The Court did not outline repayment mechanics, but the dissent warned of the fiscal implications if significant reimbursements are required.

At an operational level, many retailers have already embedded tariff costs into consumer pricing, renegotiated supplier contracts, or diversified production away from China toward Vietnam, India, and parts of Latin America. The prospect of a temporary 15% tariff layered onto an unsettled legal backdrop leaves brands navigating overlapping cost structures and sourcing commitments with limited visibility into long-term trade policy stability. In some cases, companies that shifted production to mitigate earlier tariffs may now find themselves locked into higher-cost arrangements even as the legal foundation of those tariffs erodes.

More broadly, the decision reinforces the Court’s continued scrutiny of expansive assertions of executive economic authority, with the majority invoking the major questions doctrine to stress that tariff policy – like taxation – rests primarily with Congress absent unmistakable statutory delegation.

THE TAKEAWAY: For global brands and retailers, the Supreme Court’s decision has not eliminated tariff volatility but instead shifted it into a more complex legal and policy landscape. The administration’s reliance on temporary tariff authority preserves near-term trade pressure while ensuring that congressional action, further litigation, and potential policy reversals will continue to shape sourcing strategies, pricing decisions, and supply chain planning – leaving stability elusive despite the Court’s intervention.
