The Tariff Landscape for Pharmaceuticals & Life Sciences
Pharmaceutical and life sciences imports occupy an unusual position in the US tariff schedule. Many finished drug products enter duty-free under Chapter 30, but the picture changes significantly at the ingredient level. Active pharmaceutical ingredients sourced from China and India (which supply the majority of the world's API volume) are exposed to Section 301 tariffs and IEEPA actions that have layered duties onto inputs that were previously low or zero-rated. Medical devices face a more complex classification environment, where the line between a duty-free instrument and a tariffed mechanical component is contested regularly at the HTS level.
A single misclassified API shipment at scale, or a medical device line entered under the wrong chapter heading for two years, represents a recoverable overpayment that most companies never pursue because they don't know it's there.
