3004.50.40.00 - Other

This HTS category, 3004.50.40.00, covers medicaments containing synthesized vitamins, excluding Vitamin B2 (3004.50.10.00), Vitamin B12 (3004.50.20.00), and Vitamin E (3004.50.30.00). The defining characteristic for inclusion here is that the vitamins within the medicament are synthesized wholly or in part from aromatic or modified aromatic industrial organic compounds. These products are intended for therapeutic or prophylactic uses and are presented in measured doses or in forms suitable for retail sale.

The distinction from its sibling categories lies specifically in the *source* of the vitamins. While all fall under "Other, containing vitamins or other products of heading 2936," this particular classification is for vitamins derived from specific chemical synthesis pathways involving aromatic compounds, distinct from those specified by their own dedicated codes (B2, B12, E). For example, a medicament containing Vitamin C synthesized from a glucose precursor through aromatic organic chemistry would likely fall here, whereas a pure Vitamin B2 preparation would be classified under 3004.50.10.00.

As this is a leaf node, there are no further subcategories. Therefore, classification within 3004.50.40.00 hinges on the precise chemical origin of the vitamin component and its inclusion in a finished medicament for therapeutic or prophylactic purposes. This requires careful examination of the product's formulation and manufacturing process to ascertain the synthesis route of the vitamin.
