Section 122 Temporary Global Tariff (15%)

After the Supreme Court struck down IEEPA tariffs on February 20, 2026 (Learning Resources v. Trump, 6-3), the President imposed a 15% temporary tariff on ALL imports under Section 122 of the Trade Act of 1974. The President announced on Truth Social an raised the rate to 15% effective Feb 24 2026 (the statutory maximum) — CBP is collecting at 15% as of April 2026. This is a 150-day emergency tariff effective February 24, 2026, expiring July 24, 2026. It applies to ALL countries including China, on top of any existing duties (Section 301, 232, etc.). Congress can extend beyond 150 days but the President cannot do so unilaterally. Two CIT lawsuits pending; 24 state AGs filed suit on March 5, 2026.

Section 232 Tariffs on Metals (Expanded April 2026)

Section 232 tariffs on steel, aluminum, and copper were significantly restructured on April 2, 2026 (effective April 6, 2026).

DERIVATIVE ARTICLES: Products substantially made of steel/aluminum/copper: flat 25% on full customs value. Metal-intensive industrial/grid equipment: 15% transitional rate (rising to 25% in 2027). Products made abroad but entirely with American-origin steel/aluminum/copper: 10%. Products containing less than 15% metal by weight: EXEMPT from Section 232 duties. KEY CHANGE: Previous system of splitting customs value between metal and non-metal content eliminated — tariffs now apply to FULL declared value. TRADE DEAL TREATMENT: Products from EU, Japan, Korea, and Switzerland/Liechtenstein receive reduced rates consistent with existing agreements. Korea retains its TRQ arrangement — steel within quota pays MFN + Section 122 only; above quota pays full 50%. 400+ new HTS codes added to derivatives list in August 2025.
