Last updated: August 2026 dataCobalamin (Vitamin B12) and its derivatives are fermentation-derived compounds used in pharmaceutical formulations, animal feed premixes, and dietary supplements, all entering under tariff line 2936260000. FDA regulates imported B12 as either a drug substance or a food/supplement ingredient, and shipments from unapproved facilities risk automatic detention. The fermentation-intensive production process means that manufacturing origin and facility registration are key compliance checkpoints for US importers.

Importers should provide a certificate of analysis confirming identity, purity, and potency; the manufacturer's facility registration number with FDA; and documentation of intended use (pharmaceutical, dietary supplement, or feed grade). For pharmaceutical-grade material, a Drug Master File reference may also be required.
All forms of Vitamin B12 and its derivatives fall under the single tariff line 2936260000 regardless of grade. However, admissibility and labeling requirements differ significantly between pharmaceutical USP grade, dietary supplement grade, and feed-additive grade — each governed by distinct FDA or USDA regulatory frameworks. Misrepresenting grade can trigger enforcement action at the port of entry.
