Are there Section 301 or Section 232 tariffs on pharmaceuticals from South Korea?

No Section 301 tariffs apply to South Korea-origin goods. Section 232 applies with a TRQ arrangement — steel within quota enters at reduced/zero Section 232; above quota faces 25%.

What is the effective total landed duty rate for importing pharmaceuticals from South Korea in 2026?

0% KORUS FTA + 0% WTO Pharma. This reflects the combined rate including base MFN replaced by KORUS preferential rate plus Section 232 tariff.

What is the most critical compliance issue for importing pharmaceuticals from South Korea that most buyers overlook?

Rules of origin compliance. KORUS preference is only valid when goods meet the specific origin threshold — typically regional value content (65-70% depending on product category) or a qualifying tariff shift. Incorrectly claiming FTA preference when documentation is insufficient results in retroactive duty assessment at the difference between preferential and MFN rates, plus potential penalties.

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.

What does the KORUS FTA cover and how do I claim preferential treatment?

The US-Korea Free Trade Agreement (KORUS, effective 2012) has phased out duties on the vast majority of US-Korea trade — most goods now enter at 0%. To claim KORUS preference, have a valid origin certification from the Korean exporter (self-certification is permitted under KORUS). Goods must meet KORUS rules of origin requiring sufficient production in the US or Korea, with country-specific RVC or tariff shift rules by HTS code.

Are Korean electronics (Samsung, LG, SK Hynix) subject to any additional US tariffs?

No. South Korea is not subject to Section 301 tariffs. Section 232 TRQ applies to Korean steel and aluminum, not electronics. Korean electronics benefit from both KORUS FTA (0%) and the ITA (0% WTO multilateral rate), providing dual zero-rating. Major Korean brands have extensive US operations that further simplify compliance for distributors and importers.

How strictly does CBP enforce KORUS rules of origin for auto parts?

CBP has significantly increased KORUS auto parts origin verification, particularly for vehicles and major components. Importers should obtain detailed origin certifications from Korean suppliers including net cost calculations and production records. Korean auto parts manufacturers supplying global OEMs typically maintain robust KORUS documentation — request it proactively rather than waiting for a CBP CF-28 inquiry.
