U.S. imports of antibiotics, not elsewhere specified (HS 294190) totaled $28.4M in August 2026, imported from 28 countries.
Importers of Antibiotics, Not Elsewhere Specified paid $25K in duties in August 2026, an effective tariff rate of 0.09% of the $28.4M imported — duty actually collected as a share of that value, not the published tariff schedule. Antibiotics, Not Elsewhere Specified imports of $28.4M in August 2026 ran 27% below the year-to-date monthly average of $38.8M.
Last updated: August 2026 dataAntibiotics not classified under the named headings for penicillins, streptomycins, tetracyclines, chloramphenicol, or erythromycin fall here, covering a chemically diverse range including aminoglycosides, natural antibiotics, and aromatic or modified-aromatic synthetic antibiotics. The US schedule subdivides the heading into five 10-digit lines — aminoglycoside antibiotics (2941901010), natural antibiotics NESOI (2941901050), aromatic or modified-aromatic antibiotics excluding natural (2941903000), other non-natural non-aromatic antibiotics (2941905000), and a residual NESOI line (2941906000) — making precise chemical characterization essential for correct entry. Italy leads US supply under this heading, followed by China and Denmark, a distribution that reflects both European fermentation expertise and Chinese bulk API capacity. Chinese-origin goods may be subject to Section 301 tariffs.

Classification among the five 10-digit lines turns on two axes: whether the antibiotic is natural (fermentation-derived) or synthetic, and whether it has an aromatic or modified-aromatic chemical structure. Importers should obtain a detailed certificate of analysis and, for novel compounds, consider requesting a binding ruling from CBP to avoid misclassification penalties.
Italy hosts several major fermentation-based pharmaceutical manufacturers with long-standing expertise in producing complex natural and semi-synthetic antibiotics, including glycopeptides and other specialty classes that fall outside the named headings. This industrial heritage positions Italian producers as preferred GMP-certified sources for high-value antibiotic APIs not easily sourced elsewhere.
