3002.15.00.91 - Other

This HTS category, specifically 3002.15.00.91, encompasses immunological products that are not specifically classified under other headings within 3002.15.00. It includes those presented in measured doses or in forms or packings ready for retail sale. The key characteristic is their biological origin and their application in stimulating or modulating immune responses for therapeutic, prophylactic, or diagnostic purposes. These products are typically complex biological molecules, but this particular subheading covers those that do not fit into more specific classifications.

This subheading is distinguished from its sibling category, 3002.15.00.11, by the absence of monoclonal antibodies. While both deal with immunological products in retail-ready formats, 3002.15.00.11 is exclusively for products containing monoclonal antibodies, which are a specific class of highly targeted proteins. Therefore, 3002.15.00.91 serves as a residual category for other immunological products meeting the dosage and packaging criteria.

As this is a leaf node within the HTS, there are no further subcategories. Classification within this code hinges on the determination that the immunological product is indeed intended for therapeutic, prophylactic, or diagnostic use, is presented in a measured dose or retail-ready format, and does not contain monoclonal antibodies which would direct it to the preceding sibling category. Examples might include certain cytokines, interleukins, or other biologically derived immune modulators packaged for direct administration or sale to end-users, provided they are not otherwise specified.
