In a swift response to a major defeat, President Donald Trump signed a proclamation on February 20, 2026, imposing a temporary 10% ad valorem import duty on most goods entering the United States from around the world. This move came just hours after the U.S. Supreme Court ruled 6-3 that his previous sweeping tariffs—enacted under the International Emergency Economic Powers Act (IEEPA)—exceeded presidential authority and were unlawful.

The new tariff, invoked under the rarely used Section 122 of the Trade Act of 1974, addresses what the administration calls “fundamental international payment problems” and aims to rebalance U.S. trade relationships.

Key Details

• Effective Date: February 24, 2026, at 12:01 a.m. EST.
• Duration: Limited to 150 days (unless Congress extends it via legislation) — the maximum allowed under Section 122, making this a short-term measure. No prior U.S. president has used this provision for tariffs.
• Scope: A flat 10% surcharge on imports from all countries, applied on top of existing most-favored-nation (MFN) or other normal tariffs.
• Exemptions (from White House proclamation and fact sheet):
  • Critical minerals, metals (including currency/bullion), energy products, and natural resources/fertilizers not sufficiently available domestically.
  • Specific agricultural products (e.g., beef, oranges, tomatoes).
  • Pharmaceuticals and active ingredients.
  • Certain electronics, passenger vehicles, light trucks, buses, heavy-duty vehicles, and related parts.
  • Aerospace products and parts.
  • Informational materials (books, publications), donations, and accompanied personal baggage.
  • Goods already subject to separate tariffs (potentially unaffected by the court’s ruling on IEEPA duties).
  • Possible carve-outs or protections for compliant partners under agreements like the USMCA.

Background: Supreme Court Ruling and Immediate Pivot

On February 20, 2026, the Supreme Court invalidated broad IEEPA-based tariffs (including a 10% baseline “reciprocal” tariff and higher rates on specific countries for trade deficits, fentanyl flows, etc.), ruling that the 1977 law does not authorize presidential tariffs. Chief Justice John Roberts wrote the majority opinion, emphasizing limits on executive power over taxation and commerce.

Trump called the decision “deeply disappointing,” criticized some justices harshly during a White House briefing, and labeled them “fools” or worse in public statements. He quickly shifted to Section 122 authority, signing the order from the Oval Office and announcing it on Truth Social. Treasury Secretary Scott Bessent stated that combining this with potential future actions under Sections 301 (unfair practices) and 232 (national security) would maintain roughly similar tariff revenue in 2026.

Global Impact and Reactions

• Economic Effects: The tariff could raise costs for U.S. importers and consumers on non-exempt goods, potentially fueling inflation while aiming to protect domestic industries and reduce trade deficits. Global markets showed volatility following the announcement, with uncertainty over supply chains and retaliatory risks.
• International Responses: Trading partners worldwide face higher barriers. Exemptions may ease pressure on key sectors (e.g., energy, pharma, autos). Allies under deals like USMCA could see limited impact. Retaliation remains possible from major exporters like China, the EU, or others, though the temporary nature limits long-term escalation.
• Broader Implications: This highlights persistent U.S. protectionism in the Trump era. Billions in potential refunds for invalidated IEEPA tariffs are unresolved, likely leading to prolonged litigation. Congress could influence or override the new tariff after 150 days.

The White House emphasizes this as a tool to safeguard American workers, farmers, and manufacturers amid ongoing trade imbalances.
