3003.39 - Other:

This HTS category, 3003.39, encompasses medicaments that are mixtures of two or more constituents intended for therapeutic or prophylactic uses, but are not in measured doses or retail packaging. Crucially, these products must contain hormones or other substances of heading 2937, distinguishing them from other medicaments not containing these specific active ingredients.

Within this group, 3003.39 serves as a residual category for hormone-containing medicaments that do not fall under the more specific sibling category of 3003.31, which exclusively covers medicaments containing insulin. Therefore, any medicament fitting the general description of 3003.3, but not classified as containing insulin, will be evaluated under 3003.39.

The subcategories within 3003.39 further refine the classification based on the nature of the hormone-containing mixture. The subdivision 3003.39.10.00 is reserved for artificial mixtures of natural hormones, while the residual category 3003.39.50.00 covers all other medicaments that meet the criteria of 3003.39 but are not artificial mixtures of natural hormones. This hierarchical structure allows for precise identification of specialized medicinal products.
