View full HS code details

Riboflavin, or Vitamin B2, is classified under HS code 2936.23, a specific designation within the organic chemicals chapter of the Harmonized System. Heading 2936 is reserved for provitamins and vitamins, including their derivatives and concentrates. The classification logic for vitamins is based on their chemical structure and purity. Riboflavin-5'-phosphate and other pure derivatives are included here, provided they are not mixed with other substances for specific therapeutic or prophylactic uses. The unmixed requirement is a key factor; once riboflavin is blended with other vitamins or minerals into a final dosage form like a tablet or capsule, it typically moves to Chapter 30 (Medicaments). Similarly, if it is added to a food preparation as a fortificant, it may fall under Chapter 21. The 2936.23 code is used primarily for the bulk chemical trade of the vitamin, which is then used as a raw material in the pharmaceutical, food, and animal feed industries. Accurate classification ensures that the chemical is monitored correctly for safety standards and trade agreements related to pharmaceutical ingredients and nutritional additives.

Common Misclassification

Riboflavin is often misclassified under 2106.90 as a food supplement or 3004.50 as a vitamin medicament. The distinction is that 2936.23 is for the pure chemical substance. If the product contains additives like flavoring, sugar, or other vitamins, it can no longer stay in Chapter 29 and must be classified based on its final preparation and use.
