HS code for Pyridoxine: 2936.25
Vitamins, vitamin B6 and its derivatives, unmixed.
Classification of pyridoxine under HS 2936.25
Pyridoxine, commonly known as Vitamin B6, is classified under HS code 2936.25. This code is found within Chapter 29, which covers organic chemicals, and specifically under heading 2936, which is dedicated to provitamins and vitamins, natural or reproduced by synthesis. The classification of pyridoxine is highly specific because the Harmonized System provides individual subheadings for the most common vitamins. To qualify for 2936.25, the substance must be unmixed and not yet prepared as a medicament for retail sale. This includes pyridoxine hydrochloride and other derivatives of Vitamin B6. The classification is governed by the chemical structure and purity of the compound. According to Chapter 29 Note 1, the products of this chapter must be separate chemically defined organic compounds. If the pyridoxine is part of a multi-vitamin complex or is prepared in measured doses for therapeutic use, it may move to other chapters, such as Chapter 21 for food supplements or Chapter 30 for medicaments. However, in its pure chemical form, used as a raw material for the pharmaceutical or food industry, it remains strictly within 2936.25. This code is essential for customs to track the trade of specific vitamins and ensure appropriate regulatory oversight for chemical substances.

Codes often confused with 2936.25
Common mistake. Pyridoxine is often misclassified under 2106.90 (food preparations) when it is sold as a dietary supplement. It is also confused with 3004.50, which covers vitamins put up in measured doses for medical use. The distinction depends on whether the product is a bulk chemical (2936) or a finished retail product (2106 or 3004).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
