President Trump's Section 232 pharmaceutical tariffs took effect Friday July 31, 2026 for the 17 companies named in the initial tranche of the Section 232 national-security investigation. The Section 232 pathway allows the President to impose tariffs on imports that threaten national security; the pharmaceutical investigation was announced April 1, 2025 by the Commerce Department under the Trump administration and formally initiated April 30, 2026. Companies in the initial tranche face tariffs on active pharmaceutical ingredient (API) and finished-drug imports depending on manufacturing-location documentation; the broader pharmaceutical industry faces a September 29 deadline for additional tariff applicability. Peptide-and-obesity-relevant sponsors including Novo Nordisk (Wegovy/Ozempic semaglutide, primarily manufactured in Denmark), Eli Lilly (Zepbound/Mounjaro tirzepatide and Foundayo orforglipron, primarily manufactured in Ireland and Indiana), Merck (LIPFENDRA/enlicitide macrocyclic peptide PCSK9, manufacturing across US and Ireland), AstraZeneca (elecoglipron and biologics portfolio), Sanofi (Dupixent dupilumab), AbbVie (Skyrizi and Rinvoq), Roche, Bristol-Myers Squibb, Amgen, Pfizer, and Biogen all face potential 25% import duties depending on manufacturing-location documentation. President Trump also announced Tuesday July 21 that imported generic drugs would face zero tariffs for two years starting August 2028, providing a two-year runway before generic tariffs begin.
