2936.26.00.00 - Vitamin B12 (Cyanocobalamin and related compounds with Vitamin B12 activity) and its derivatives

This HTS classification covers Vitamin B12, also known as Cyanocobalamin, and its related compounds that exhibit Vitamin B12 activity. Derivatives of Vitamin B12 used primarily for their vitamin properties are also included within this category. This designation is specific to the provitamins, vitamins, and their derivatives, whether occurring naturally or synthesized, including their natural concentrates and intermixtures, irrespective of whether they are dissolved in a solvent.

This category is distinguished from other sibling categories by its focus solely on Vitamin B12 and its active derivatives. For instance, while 2936.21.00.00 pertains to Vitamin A, and 2936.22.00.00 to Vitamin B1 (Thiamine), this specific classification is reserved for the cobalamin group of vitamins. The crucial defining characteristic for classification here is the presence of the unique chemical structure and biological function of Vitamin B12.

As this is a leaf node in the HTS structure, there are no further subcategories for Vitamin B12 and its derivatives. Therefore, classification under 2936.26.00.00 will rely on confirming the identity of the substance as Vitamin B12 or a direct derivative thereof possessing Vitamin B12 activity. This would include pure Cyanocobalamin, Hydroxocobalamin, Methylcobalamin, and Adenosylcobalamin, provided they are presented for their primary vitamin use.
