3001.90.01 - Other

This HTS category, "Other," within the broader classification of pharmaceutical products, encompasses human or animal substances prepared for therapeutic or prophylactic uses that are not elsewhere specified or included under headings like extracts of glands or other organs. This includes substances derived from various animal or human sources that have undergone preparation for medicinal purposes, but do not fit into the more specific categories of dried glands/organs or their extracts. The key characteristic is their intended use in therapy or prevention of disease.

Crucially, this "Other" category serves as a residual classification. It is distinguished from its sibling category, 3001.20.00.00 (Extracts of glands or other organs or of their secretions), by the form and origin of the substance. While 3001.20.00.00 specifically covers derived liquid or semi-solid extracts, this category is for other prepared therapeutic substances that are not extracts and are not simply dried glands or organs. It also excludes substances covered by other chapters or headings within the HTS.

The subcategories under 3001.90.01.90, also labeled "Other," represent further refinements within this residual classification. These subdivisions likely exist to address specific types of prepared therapeutic substances that, while not fitting into the more defined categories, still require differentiation for accurate classification and trade purposes. This allows for greater specificity when dealing with a diverse range of less common pharmaceutical preparations derived from biological sources.
