Last updated: August 2026 dataFinished-dose antibiotics outside the penicillin/streptomycin family — including macrolides (azithromycin, erythromycin), tetracyclines (doxycycline, tetracycline), lincosamides (clindamycin), cephalosporins (cefdinir, cefepime, ceftazidime), carbapenems (meropenem), and glycopeptides (vancomycin) — are each assigned dedicated 10-digit tariff lines, making this one of the most granularly subdivided pharmaceutical headings in the US schedule. India leads supply, followed by Italy, China, Switzerland, and Portugal. The breadth of named drug lines reflects both the commercial scale of these generics and heightened regulatory interest in tracking hospital-critical antibiotics. Importers should note that several molecules in this heading, particularly carbapenems and vancomycin, are considered last-resort antibiotics subject to close FDA scrutiny for manufacturing quality.

Classification of combination antibiotic products depends on which antibiotic is considered the essential character or is specifically named in a tariff line. Heading 300410 covers combinations containing penicillins, while 300420 covers other antibiotics. If a combination contains a penicillin alongside another antibiotic class, it will generally fall under 300410 unless a specific line in 300420 more precisely describes it. A binding ruling from CBP is advisable for novel combinations.
Certain finished pharmaceutical products, including some antibiotic dosage forms, have been subject to Section 301 tariffs when imported from China. Importers should verify the current Section 301 status for the specific 10-digit HTS line applicable to their product, as exclusions and modifications have changed over time. A licensed customs broker can confirm current applicability.
