3003.90.01.80 - Other

This HTS category, 3003.90.01.80, encompasses medicaments containing two or more mixed constituents for therapeutic or prophylactic use, not presented in measured doses or for retail sale. Specifically, it covers anti-infective medicaments that do not fall under more specific classifications for antivirals, antifungals, or antiprotozoals. Examples within this subcategory might include broad-spectrum antibacterial combinations or multi-agent treatments for complex infections where the individual components are not separately categorized as primarily antiviral, antifungal, or antiprotozoal in their intended use.

The distinction between this "Other" anti-infective category and its sibling subheadings lies in the primary pharmacological action. Subheadings 3003.90.01.20 (Antivirals), 3003.90.01.40 (Antifungals), and 3003.90.01.60 (Antiprotozoals) are reserved for medicaments whose predominant therapeutic purpose is directed against specific classes of pathogens. This residual category is therefore crucial for accurately classifying anti-infective mixtures where the primary indication is not singularly a viral, fungal, or protozoal infection, or when the combination addresses multiple pathogen types without a specific primary designation that aligns with the more granular sibling categories.

As this is a leaf node within the HTS structure, there are no further subdivisions. Therefore, classification within 3003.90.01.80 relies on ensuring the product meets the general criteria for medicaments under heading 3003 (mixed constituents for therapeutic or prophylactic use, not in measured doses or for retail sale) and its specific designation as an anti-infective, while also confirming it does not fit the more precise definitions of antivirals, antifungals, or antiprotozoals. The absence of subcategories emphasizes that this designation is for residual anti-infective mixtures that do not warrant a more specialized classification.
