Last updated: July 2026 dataA residual catch-all for unmixed vitamins not covered by the preceding specific headings, this group encompasses folic acid, niacin and niacinamide (with pharmaceutical-grade niacin broken out separately at the 10-digit level), Vitamin D forms, biotin, and other non-aromatic vitamins. The US schedule is notably granular: niacin is split among 2936291610 (pharmaceutical grade), 2936291620 (non-pharmaceutical grade), and 2936291630 (niacinamide), reflecting different duty treatment and regulatory pathways. Section 301 tariffs may apply to several lines depending on origin, making grade documentation and origin verification essential for cost management.

The split at the 10-digit level — 2936291610 versus 2936291620 — reflects different end-use regulatory requirements and potentially different duty rates. Pharmaceutical-grade niacin must meet USP or equivalent pharmacopeial standards and is subject to FDA drug cGMP oversight, while non-pharmaceutical grades are used in feed or food applications under separate regulatory frameworks. Misclassifying the grade can result in both duty underpayment and admissibility issues.
Biotin (Vitamin B7/H) is classified under 2936295030. As a dietary supplement ingredient and pharmaceutical excipient, it is subject to FDA oversight at entry. Importers should ensure the certificate of analysis specifies purity and intended use, and verify whether Section 301 tariffs apply based on the country of manufacture.
