Last updated: May 2026 dataInsulin and its pharmaceutical salts — including both animal-derived and recombinant human insulin — enter the US under tariff line 2937120000 and are among the most tightly regulated pharmaceutical imports, subject to FDA biologics or drug approval requirements depending on the specific product form. The US insulin market has historically relied on a small number of large manufacturers, but biosimilar insulin approvals have begun to diversify the supply landscape. Importers must ensure that each product is covered by an FDA-approved application and that the manufacturing facility is registered and inspected.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — heading 293712 covers insulin and its salts regardless of source, so both animal-derived and recombinant forms enter under 2937120000. However, the FDA regulatory pathway differs: animal-derived insulins are regulated as drugs under the Federal Food, Drug, and Cosmetic Act, while recombinant human insulins and biosimilar insulins may be regulated as biologics under the Public Health Service Act. The applicable approval pathway affects the documentation required at entry.
A first-time importer should confirm that the specific insulin product has an FDA-approved NDA, BLA, or ANDA covering the imported formulation; verify that the foreign manufacturing facility is registered with FDA and has been inspected; and ensure that import entry documentation references the correct approval. Working with a licensed customs broker experienced in pharmaceutical imports is strongly recommended, as FDA may place the product on import alert if any of these conditions are not met.
