For American businesses that have spent years navigating the turbulent waters of Trump’s trade policy, the announcement of a new 15% tariff on all imports was met with a mixture of alarm, frustration, and grim resignation. Top trade associations had barely begun processing the Supreme Court’s landmark ruling against the IEEPA tariffs when the new rate was announced — a reminder that in the current environment, legal victories can be quickly overtaken by executive action.
The National Federation of Independent Business, major manufacturing associations, and retail groups had all been vocal about the economic damage caused by the original IEEPA tariffs, and many had been preparing to seek refunds following the court’s ruling. Trump’s announcement that refunds would not come without a lengthy legal battle dampened those expectations considerably. Business leaders were left weighing the costs of litigation against the prospect of eventual recovery.
The new tariffs carry important exemptions that offer some relief to specific sectors. Critical minerals, metals, and pharmaceuticals are exempt from the 15% levy, as are USMCA-compliant goods from Canada and Mexico. For businesses in these categories, the new tariff announcement is less directly impactful. For everyone else — retailers importing consumer goods, auto parts manufacturers, electronics companies — the additional tariff burden is real and immediate.
International business relationships are also under strain. Companies that had built supply chains around the premise of a 10% tariff environment now face a 15% reality, requiring fresh rounds of cost modeling, supplier renegotiation, and strategic reassessment. The constant shifting of trade policy terms makes long-term planning extraordinarily difficult and adds a premium to the cost of doing business with the US.
Against this backdrop, US business associations are mounting political pressure on Congress to assert its constitutional role in trade policy. The Supreme Court’s ruling affirmed that tariffs of the IEEPA magnitude require congressional approval — a principle that many business groups see as their best long-term protection against future unilateral tariff escalations. Whether Congress will act before the 150-day clock on the new provision expires is a question businesses are watching closely.
