HS code for Cobalamin: 2936.26

Vitamins, vitamin B12 and its derivatives, unmixed.

Classification of cobalamin under HS 2936.26

Cobalamin, commonly known as Vitamin B12, is classified under HS code 2936.26. This code is situated within Chapter 29, which covers organic chemicals. Heading 2936 is specifically designated for provitamins and vitamins, including their derivatives used primarily as vitamins. Subheading 2936.26 is the specific international code for Vitamin B12 and its derivatives. For a product to be classified here, it must be unmixed. This means the substance must be the pure vitamin or a derivative (such as cyanocobalamin or methylcobalamin) without the addition of other vitamins, minerals, or medicinal substances, except for stabilizers or solvents necessary for preservation or transport. The classification is based on the chemical identity of the molecule as a vitamin rather than its end-use in food or medicine.

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).
