U.S. President Donald Trump announced a new 10% global tariff on Friday, invoking Section 122 of the Trade Act of 1974 just hours after the Supreme Court of the United States struck down his earlier emergency tariff regime.

The move is designed to replace a portion of the sweeping duties previously imposed under the International Emergency Economic Powers Act (IEEPA), which the Court ruled exceeded presidential authority. In its decision, the Court found that IEEPA does not grant the executive branch the power to levy broad-based tariffs, reaffirming that such authority rests with Congress.

Under Section 122, the president may impose tariffs of up to 15% for a maximum of 150 days to address “large and serious” balance-of-payments issues. The provision does not require formal investigations or extended procedural steps, giving the administration a faster route to implement temporary duties.

Trump said the new 10% tariff would apply in addition to existing trade measures. “We have alternatives, great alternatives,” he said, signaling that additional tools remain available. He added that the new approach could generate increased revenue and strengthen the U.S. trade position.

In parallel, the administration is launching several investigations under Section 301 of the Trade Act, targeting what it described as unfair trade practices by foreign governments and companies. Section 301 probes typically take months to complete and can result in more targeted, longer-term tariffs.

While the Section 122 tariffs provide an immediate mechanism to maintain pressure on trading partners, their 150-day limit underscores the temporary nature of the measure. Analysts note that unless extended through congressional action or replaced by other authorities, the new duties could expire by mid-year, potentially prolonging trade uncertainty for global supply chains.

The shift to alternative statutory tools had been widely expected following the Court’s ruling, but the rapid rollout of a new across-the-board tariff signals that the administration intends to continue its assertive trade strategy despite the legal setback.
