HS Code for Vitamin B1

Vitamin B1, chemically known as thiamine, is classified under HS code 2936.22. This classification is determined by the General Rules for the Interpretation of the Harmonized System (GRI), specifically focusing on Chapter 29 for organic chemicals. Heading 2936 covers vitamins and their derivatives. Subheading 2936.22 is specifically designated for Vitamin B1 and its derivatives, such as thiamine hydrochloride and thiamine mononitrate, provided they are not mixed with other substances except for stabilization or transport purposes. The classification depends on the chemical identity of the substance as a vitamin. If the product is presented in a form that includes additives for nutritional purposes or is packaged for retail sale as a dietary supplement, it may move to other chapters, but the bulk chemical substance remains strictly under 2936.22. This code is essential for international trade to ensure that pure thiamine products are distinguished from other heterocyclic compounds. The purity and the specific chemical structure of the thiamine molecule are the primary factors that customs authorities use to verify the application of this specific subheading.

Products Included

• Thiamine hydrochloride
• Thiamine mononitrate
• Thiamine chloride
• Thiamine phosphate esters
• Pure thiamine powder

Common Misclassification

Vitamin B1 is often misclassified under HS code 2933.59, which covers heterocyclic compounds with a pyrimidine ring. While thiamine does contain a pyrimidine ring, Note 1 to Chapter 29 and the specific heading for vitamins (2936) take precedence. It is also sometimes incorrectly placed in 2106.90 when intended for use as a food additive in mixtures.
