On September 28, 2026, U.S. Customs and Border Protection (CBP) issued CSMS #70054007, providing updated guidance on the implementation of the Section 232 duties on imported pharmaceuticals and pharmaceutical ingredients imposed under Presidential Proclamation 11020. The guidance also incorporates the Department of Commerce’s (DOC) September 23, 2026 Federal Register notice (91 FR 60360), which identifies products and jurisdictions eligible for certain duty-free treatment and implements several technical corrections to the pharmaceutical tariff regime.
