After Supreme Court Rebuke, Trump Uses Section 232 to Impose Up to 100% Tariffs on Some Patented Drug Imports and Adjust Steel/Aluminum Product Duties

Citing national‑security authority under Section 232, the administration has imposed tariffs of up to 100% on certain patented brand‑name pharmaceutical imports under a tiered regime—100% for products listed in Annex I, 20% for firms with Commerce‑approved onshoring plans (rising to 100% by 2030), and a zero‑tariff option for companies that both onshore production and sign Most‑Favored‑Nation pricing agreements under the TrumpRx initiative; generics and U.S.‑origin drugs are excluded “at this time,” and preferential rates (e.g., 15% for Japan/EU/South Korea/Switzerland, 10% for the U.K.) are provided for some allies. The tariffs (phased in for some firms on July 31 and others on Sept. 29, 2026) come alongside adjustments to duties on products containing steel and aluminum and mark the first expansion of duties since the Supreme Court partially struck down his earlier broad tariff program in February.

📌 Key Facts

  • President Trump is imposing tariffs as high as 100% on certain imported patented (name‑brand) pharmaceuticals under a Section 232 national‑security proclamation; a senior administration official called the 100% level a "100% tax" on drugs made abroad.
  • News outlets report the measure as an imposed policy (not merely a proposal) with specific effective dates: tariffs begin applying July 31, 2026 for some companies and September 29, 2026 for others.
  • The administration is implementing a tiered tariff regime: a default 100% tariff on products listed in Annex I; a 20% tariff for companies with Commerce Department‑approved onshoring plans (rising to 100% by 2030); and a zero‑tariff option for firms that onshore production and sign "Most‑Favored‑Nation" pricing agreements under the TrumpRx initiative.
  • The plan includes differentiated rates for certain allies: 15% for covered products from Japan, the European Union, South Korea and Switzerland, and 10% for products from the United Kingdom, with the possibility of future reductions to zero under agreements.
  • Generic drugs and pharmaceuticals of U.S. origin are explicitly excluded from these tariffs "at this time," narrowing the immediate scope to patented brand‑name products and key ingredients.
  • The administration cited quantitative context to justify the national‑security rationale: roughly 53% of patented pharmaceutical products distributed in the U.S. are produced abroad, while about 15% of patented active pharmaceutical ingredients (by volume) are made domestically.
  • The move follows a partial Supreme Court rebuke in February that struck down the administration's earlier broad tariff program; this action is the first expansion or reapplication of duties since that decision. The administration also said it is "adjusting" tariffs on products that contain steel and aluminum.
