Last updated: August 2026 dataThe B-vitamin complex encompasses a chemically diverse group — thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cyanocobalamin (B12) — each traded as a distinct bulk chemical with its own purity specifications and supply chains. Bulk B vitamins are widely used as pharmaceutical APIs, dietary supplement ingredients, and animal-nutrition additives, making FDA entry review the standard admissibility checkpoint for human-use grades. China is a dominant global producer of several B-vitamin compounds, and shipments from that origin may be subject to Section 301 tariff measures depending on the specific HTS classification. Importers should verify current Section 301 applicability and confirm that certificates of analysis meet FDA or USP specifications.

Many bulk B-vitamin compounds imported from China fall under HTS chapters that are subject to Section 301 tariff measures. The specific rate and applicability depend on the precise 10-digit HTS classification of each compound. Importers should work with a licensed customs broker to confirm current Section 301 list coverage and any applicable exclusions before shipment.
FDA expects that bulk B vitamins intended for pharmaceutical or dietary supplement use conform to USP or equivalent pharmacopeial standards. Importers should provide certificates of analysis showing identity, purity, and potency, as well as the name and address of the foreign manufacturer, to support FDA's admissibility determination at the port of entry.
