3003.90.01.20 - Antivirals

This HTS subheading, 3003.90.01.20, specifically classifies "Antivirals" that are medicaments composed of two or more constituents mixed together for therapeutic or prophylactic uses. Crucially, these products are not presented in measured doses or in forms or packings intended for retail sale, aligning with the broader scope of heading 3003. The defining characteristic of goods under this code is their primary function in combating viral infections.

To distinguish this category from its siblings, it is important to note that 3003.90.01.40 covers antifungals, which target fungal infections, while 3003.90.01.60 addresses antiprotozoals, used against infections caused by protozoa. Subheading 3003.90.01.80 is a residual category for other anti-infective medicaments not otherwise specified. Therefore, this subheading is exclusively for complex pharmaceutical mixtures formulated to inhibit or eliminate viral replication or activity.

As this subheading represents a leaf node within the HTS, there are no further subcategories. Classification under 3003.90.01.20 relies on identifying the presence of active antiviral agents within a multi-constituent mixture, intended for non-retail bulk distribution, and specifically targeted at viral pathogens. Examples might include bulk pharmaceutical preparations for the treatment of influenza, HIV, or hepatitis, where the finished product is not yet packaged for individual patient use.
