U.S. exports of vaccines, toxins, microbial cultures & related biological products (nesoi) (HS 300249) totaled $232.5M in July 2026.
Importers of Vaccines, Toxins, Microbial Cultures & Related Biological Products (NESOI) paid $97K in duties in July 2026 — an effective duty rate of 10% on $968K in dutiable value, based on actual customs collections rather than the published tariff schedule. Vaccines, Toxins, Microbial Cultures & Related Biological Products (NESOI) imports of $88.6M in July 2026 ran 12% above the year-to-date monthly average of $79.0M.
Last updated: July 2026 dataResidual biological preparations — including microbial cultures, toxins not elsewhere specified, and other vaccines outside the dedicated human and veterinary headings — are captured here, along with the specifically enumerated tariff line for ricin (3002490010), a select agent subject to strict CDC and USDA oversight. Ireland, Belgium, and Germany are the primary US source countries for the broader NESOI category (3002490050), consistent with Europe's dominant role in advanced biologics manufacturing. Importers of microbial cultures and toxins must navigate both FDA biologics regulations and, where applicable, CDC/USDA select-agent program requirements, which impose registration, security, and transfer restrictions well beyond standard pharmaceutical entry procedures.

Ricin is classified as a CDC/USDA select agent, meaning its possession, use, and transfer are regulated under the Federal Select Agent Program. Importers must be registered with the appropriate federal select-agent program, obtain prior approval for transfer, and maintain strict security and inventory controls. Standard FDA pharmaceutical import procedures are insufficient — select-agent compliance is a separate, parallel requirement.
Classification depends on the culture's intended use and presentation. Cultures intended for therapeutic or prophylactic use in humans typically fall within Chapter 30, while cultures for industrial fermentation or research may classify elsewhere (e.g., Chapter 21 or 38). A licensed customs broker with pharmaceutical experience should review the product's technical documentation, including its intended use and regulatory status, before filing entry.
