3004.90.92.80 - Antihistamines

This HTS category, 3004.90.92.80, specifically covers antihistamines classified under medicaments for therapeutic or prophylactic uses, presented in measured doses or retail packaging. These products are intended to treat or prevent conditions related to allergic reactions by blocking the action of histamine, a chemical released by the body during such responses. The classification assumes the product meets the general criteria for medicaments as outlined in Chapter 30, including being for human or veterinary use and prepared in forms suitable for direct administration.

This subheading is distinguished from its siblings by its specific focus on antihistamines. For instance, HTS 3004.90.92.84 is reserved for medicaments containing albuterol sulfate, a bronchodilator typically used for respiratory conditions. This current category, 3004.90.92.80, is for antihistamines that do not fall under that specific bronchodilator classification. The sibling 3004.90.92.89, "Other," serves as a residual category for medicaments affecting the eyes, ears, or respiratory system that are not explicitly covered by the preceding subheadings within this group.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges on the precise identification of the active ingredient as an antihistamine and its presentation in measured doses or retail packaging, fitting within the broader scope of medicaments affecting the respiratory system, eyes, or ears, but not being a bronchodilator like albuterol sulfate.
