3004.50.20.00 - Vitamin B12

This HTS category, 3004.50.20.00, specifically covers Vitamin B12, also known as cyanocobalamin or hydroxocobalamin, when presented as a medicament. These products are intended for therapeutic or prophylactic uses and are packaged in measured doses, such as tablets, capsules, injections, or transdermal patches, ready for retail sale. The classification requires that the Vitamin B12 be synthesized wholly or in part from aromatic or modified aromatic industrial organic compounds, aligning with the overarching provisions for medicaments containing vitamins.

This classification is distinguished from its siblings by the specific vitamin content. For instance, 3004.50.10.00 pertains to Vitamin B2 (riboflavin), and 3004.50.30.00 covers Vitamin E (tocopherols). The "Other" category at this level (3004.50.40.00) would encompass other vitamins synthesized from aromatic or modified aromatic organic compounds not otherwise specified. The precise identification of Vitamin B12 is crucial for correct classification within this sub-heading.

As this is a leaf node within the HTS, there are no further subcategories. Classification therefore concludes at the HTS code 3004.50.20.00, provided the goods meet all the preceding criteria of Chapter 30, specifically heading 3004, and the conditions for vitamins synthesized from aromatic or modified aromatic industrial organic compounds. The focus remains on the pharmaceutical presentation and the origin of the vitamin synthesis.
