3004.10.10.20 - Singles

This HTS category, 3004.10.10.20, specifically covers "Singles" of medicaments containing penicillin G salts. These are pharmaceutical preparations designed for therapeutic or prophylactic purposes, presented in measured doses or retail packaging. The defining characteristic for this classification is the presence of penicillin G salts as the active pharmaceutical ingredient, excluding other types of penicillins or derivatives.

It is crucial to distinguish this category from its sibling, 3004.10.10.45, "Combination antibiotics." While both fall under the umbrella of medicaments containing penicillins, "Singles" refers to products where penicillin G salts are the sole or primary antibiotic component. "Combination antibiotics," conversely, would encompass products that include penicillin G salts alongside other distinct antibiotic substances. This distinction is critical for accurate tariff application.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification hinges on the precise identification of penicillin G salts as the active ingredient and the absence of other co-formulated antibiotics. Examples falling under this code would include single-ingredient formulations of penicillin G potassium or penicillin G procaine, put up in blister packs, vials, or other forms ready for patient administration.
