Adjusting Imports of Pharmaceuticals and Pharmaceutical Ingredients Into the United States

A Section 232 measure is a U.S. trade action based on a finding that certain imports may affect national security. For pharmaceuticals and pharmaceutical ingredients, the covered goods may include finished medicines, active pharmaceutical ingredients (APIs), or other specified inputs, depending on the official measure and its product scope. Section 232 treatment can involve additional import requirements or duties, but the exact result depends on the applicable notice and product classification.

This type of measure typically affects manufacturers, distributors, wholesalers, and retailers importing covered products into the United States. It matters because an importer must determine whether the goods fall within the defined scope, classify them under the correct Harmonized Tariff Schedule of the United States (HTSUS) subheading, and apply the required entry reporting and payment rules. A product’s tariff classification, country of origin, composition, and intended use may all be relevant; when the scope is unclear, a customs broker or trade attorney may be needed.

What to check

• Read the official measure, scope language, and any annexes to identify which finished pharmaceuticals, APIs, or ingredients are covered.
• Confirm the HTSUS classification for each product and do not rely only on a supplier’s description or commercial invoice.
• Verify the product’s country of origin under U.S. customs origin rules, including whether processing or manufacturing changed its origin.
• Check whether the measure provides exclusions, exemptions, quota treatment, certifications, or special entry instructions for the product or importer.
• Coordinate with your customs broker and review official U.S. Customs and Border Protection guidance before filing entries when classification or scope is uncertain.
