3004.42.00.00 - Containing pseudoephedrine (INN) or its salts

This HTS category, 3004.42.00.00, specifically covers medicaments containing pseudoephedrine (INN) or its salts, intended for therapeutic or prophylactic uses. These products are presented in measured doses or retail packaging, consistent with the broader scope of heading 3004. This includes oral tablets, capsules, syrups, and other dosage forms where pseudoephedrine is the active pharmaceutical ingredient or a significant component.

The distinction from sibling categories is crucial for accurate classification. While all fall under medicaments containing alkaloids or their derivatives, this specific code differentiates itself from 3004.41.00.00 (containing ephedrine or its salts) and 3004.43.00.00 (containing norephedrine or its salts) by the unique chemical identity of pseudoephedrine. The "Other" category (3004.49.00) is reserved for medicaments containing different alkaloids or derivatives not otherwise specified.

As this is a leaf node, there are no further subcategories. Therefore, classification within 3004.42.00.00 relies directly on the presence of pseudoephedrine or its salts as the key identifying characteristic of the medicament. Proper identification of the active ingredient through product labeling, ingredient lists, or laboratory analysis is paramount for correct customs declaration.
