On February 20, 2026, the U.S. Supreme Court ruled 6-3 that President Trump exceeded his authority under the International Emergency Economic Powers Act. The decision invalidated sweeping reciprocal tariffs imposed in 2025. This marked a significant check on executive trade powers.
Here is the kicker: the ruling did not touch existing targeted tariffs under other laws. It focused solely on the emergency powers used for broad global levies.
Trump's Immediate Response
Within hours, Trump signed an executive order imposing a new 10% global tariff. He described the court decision as deeply disappointing and criticized certain justices. The president vowed to protect American workers through alternative legal routes.
What changed next: Trump invoked Section 122 of the 1974 Trade Act for the first time. This allows temporary surcharges up to 15% for up to 150 days to address balance-of-payments issues.
Details of the New 10% Tariff
The temporary 10% ad valorem duty takes effect February 24, 2026, at 12:01 a.m. EST. It applies on top of existing tariffs and lasts 150 days unless Congress extends it. The goal is to correct dollar outflows and encourage domestic production.
Treasury officials project it will maintain roughly unchanged tariff revenue in 2026 when combined with other measures.
Exemptions and Who Pays
Key Exemptions at a Glance:
- Critical minerals, energy products, and certain metals
- Select agricultural goods like beef, tomatoes, and oranges
- Pharmaceuticals, certain electronics, and vehicles
- USMCA-compliant goods from Canada and Mexico
- Aerospace products and informational materials
Why this matters: these carve-outs protect essential U.S. supply chains. Most other imports face the new layer of duty.
What Comes Next for US Trade
The administration directed investigations under Section 301 into unfair foreign practices. Trump indicated rates could rise for countries that treat the U.S. poorly. Existing Section 232 and 301 tariffs stay fully in force.
Trading partners now face a 150-day window of uncertainty. Longer-term deals and targeted probes could reshape global flows. The policy underscores tariffs as a core tool for rebalancing trade.
