Are there Section 301 or Section 232 tariffs on pharmaceuticals from Mexico?
No Section 301 or Section 232 surcharges apply to Mexico-origin pharmaceuticals. Only base MFN rates (or FTA preferential rates where applicable) apply.
What FDA requirements must be met to import pharmaceuticals into the United States?
FDA regulates pharmaceutical imports under the Federal Food, Drug, and Cosmetic Act (FD&C Act). Requirements include: (1) FDA facility registration for foreign drug manufacturers (21 CFR Part 207), (2) Current Good Manufacturing Practice (cGMP) compliance per 21 CFR Parts 210–211, (3) drug establishment registration and drug listing, (4) prior notice filing for all imported drug shipments, (5) FDA review of labeling for compliance with US requirements. FDA may place facilities on Import Alert without inspection — check the FDA OASIS system before importing from any supplier.
What are the HTS classifications and duty rates for pharmaceutical imports?
Pharmaceuticals are classified primarily under HTS Chapter 30. Key categories: medicaments in measured doses (HTS 3004) typically face 0% MFN duty as most have been bound at zero via WTO pharmaceutical agreements. Active pharmaceutical ingredients (APIs) under HTS 2941 (antibiotics) and 3003 vary between 0% and 6.5%. Biological products under 3002 are generally 0%. Despite the low or zero base tariff, ensure proper HTS classification — misclassification between Chapter 29 (organic chemicals) and Chapter 30 (medicaments) is a frequent CBP compliance issue.
Can I import pharmaceuticals from China or India given quality and regulatory concerns?
Yes, but with heightened due diligence. China and India are the two largest sources of pharmaceutical APIs and generics imported into the US. FDA has placed multiple Chinese and Indian facilities on Import Alert for cGMP violations — before importing, search the FDA Import Alert database for your specific manufacturer. Conduct pre-shipment quality testing, require cGMP certificates of analysis, and maintain full audit trail documentation. FDA import examinations for pharmaceuticals are more rigorous than most product categories and can result in detention and destruction of non-compliant shipments.
How do I claim USMCA preferential tariff treatment for goods from Mexico?
To claim USMCA preference, you (or your customs broker) must have a valid Certificate of Origin from the Mexican exporter at the time of entry. The certificate confirms rules of origin compliance and must be retained for 5 years for CBP audit purposes. You do not need to transmit it to CBP at entry, but it must be produced immediately upon request.
Are goods manufactured in Mexico from Chinese components eligible for USMCA?
Not automatically. USMCA requires sufficient transformation in North America — simple assembly of imported components without a qualifying tariff shift or meeting RVC thresholds generally does not qualify. The specific rules vary by HTS code under USMCA Annex 4-B. Consult a licensed customs broker or trade attorney to evaluate whether your specific product meets USMCA rules of origin.
What are the IMMEX program implications for importing manufactured goods from Mexico?
Mexico's IMMEX program allows manufacturers to temporarily import inputs duty-free for incorporation into export goods. IMMEX-manufactured goods exported to the US may qualify for USMCA preferential rates provided rules of origin are met. CBP expects importers claiming USMCA to verify that foreign inputs were either North American origin or sufficiently transformed — IMMEX manufacturing records are key supporting documentation.
