In April 2025, the United States introduced a new layered tariff framework targeting pharmaceutical imports and related chemicals. A baseline 10% duty was applied to all pharmaceutical products for an initial 90-day review window, after which rates are subject to increase, potentially reaching 25% or more depending on policy assessments. The administration’s approach reflects a broader goal of strengthening domestic production and reducing reliance on foreign supply chains for critical drug ingredients.

Country-specific levies under this regime disproportionately affect major API suppliers. Chinese imports may incur tariffs ranging from 104% to 245%, reflecting national security considerations, while European Union products face a 20% duty and Indian-origin ingredients attract a 27% rate. Products from Canada and Mexico not compliant with USMCA regulations are subject to a 25% tariff. Although many large-volume chemicals and select APIs received temporary exemptions, the threat of expanded duties has already prompted supply chain realignments and cost inflation across the pharmaceutical sector.

Companies are responding by diversifying sourcing strategies and accelerating reshoring initiatives. Pharmaceutical giants, including Roche, Novartis, and Johnson & Johnson, have announced multibillion-dollar investments in U.S.-based API production facilities to mitigate tariff exposure.
