3004.20.00.45 - Containing azithromycin or its salts

This HTS category encompasses pharmaceutical preparations containing azithromycin or its salts, intended for therapeutic or prophylactic use. These medicaments are presented in measured doses, suitable for retail sale, and are distinct from those containing other specific antibiotics or those falling under broader categories like vaccines or diagnostic reagents. The classification specifically targets the azithromycin component as the primary active pharmaceutical ingredient.

When classifying, it is crucial to differentiate this category from its siblings. For instance, medicaments containing clindamycin or doxycycline, despite also being antibiotics and falling under the "other, containing antibiotics" sub-heading at a higher level, are assigned to distinct HTS codes (3004.20.00.55 and 3004.20.00.65 respectively). This HTS code, 3004.20.00.45, is reserved exclusively for formulations where azithromycin is the key medicinal substance.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification relies on accurately identifying the presence and formulation of azithromycin within the medicinal product, ensuring it meets the criteria for therapeutic or prophylactic use and is packaged for retail sale. This ensures accurate duty assessment and regulatory compliance for imports and exports of these specific antibiotic preparations.
