3003.39.50.00 - Other

This HTS category, 3003.39.50.00, encompasses medicaments that are mixtures of two or more constituents intended for therapeutic or prophylactic uses, not presented in measured doses or retail packaging. Crucially, these medicaments must contain hormones or other products classified under heading 2937, but they do not fall under specific exceptions like artificial mixtures of natural hormones.

The distinction of this category lies in its broad inclusion of hormone-containing medicaments that are not specifically enumerated elsewhere at this level. For instance, unlike the sibling category 3003.39.10.00, which is reserved for "Artificial mixtures of natural hormones," this category covers a wider array of mixed hormonal preparations, as well as other medicaments derived from or containing products of heading 2937, provided they are not in a form suitable for immediate patient administration or retail sale.

As this represents a leaf node in the HTS classification, there are no further subcategories. Therefore, classification under 3003.39.50.00 hinges on fulfilling the general requirements of heading 3003 and its subheadings: the product must be a medicinal preparation containing hormones or products of heading 2937, mixed for therapeutic or prophylactic use, and not put up in measured doses or forms/packings for retail sale, while also not being specifically classified under any other more precise subheading at this level.
