HS Code 2936.26 – Vitamins; vitamin B12 and its derivatives, unmixed
HS code 2936.26 is the 6-digit subheading for vitamins, vitamin B12 and its derivatives, unmixed. It is used for cyanocobalamin, methylcobalamin, hydroxocobalamin, adenosylcobalamin and cobamamide.
What HS 2936.26 covers
This HS code covers unmixed Vitamin B12 (Cobalamins) and its derivatives, a complex water-soluble vitamin essential for nerve function, DNA synthesis, and red blood cell formation. These high-value compounds are traded globally as bulk pharmaceutical ingredients. Major importers include pharmaceutical companies for injectable solutions, oral supplements, and nasal sprays, particularly for treating pernicious anemia and other B12 deficiencies. Exporters are typically specialized biotechnology and pharmaceutical manufacturers capable of complex fermentation and purification processes. The trade is driven by the aging global population, increased awareness of B12 deficiency, and the growing vegan/vegetarian market. Critical aspects of trade involve ensuring extremely high purity, compliance with stringent pharmacopoeial standards, and maintaining cold chain logistics due to its sensitivity.

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).
