3004.43.00.00 - Containing norephedrine or its salts

This HTS classification, 3004.43.00.00, specifically covers medicaments containing norephedrine or its salts, intended for therapeutic or prophylactic uses. These products must be presented in measured doses or in forms suitable for retail sale, aligning with the broader scope of heading 3004. The inclusion of norephedrine, a sympathomimetic amine structurally similar to ephedrine and pseudoephedrine, is the defining characteristic of this category.

It is crucial to distinguish this category from its siblings. HTS code 3004.41.00.00 covers medicaments containing ephedrine or its salts, while 3004.42.00.00 is reserved for those containing pseudoephedrine (INN) or its salts. This particular classification, 3004.43.00.00, is exclusive to compounds where norephedrine is the active alkaloid or derivative present. The residual category, 3004.49.00, is for other medicaments in this subgroup not specifically classified under the preceding norephedrine, ephedrine, or pseudoephedrine subheadings.

As this is a leaf node, there are no further subcategories under 3004.43.00.00. Classification within this code therefore relies solely on the presence of norephedrine or its salts as the active pharmaceutical ingredient in medicaments prepared for therapeutic or prophylactic purposes and packaged for direct patient use. Examples would include specific pharmaceutical preparations formulated with norephedrine for conditions such as hypotension or nasal decongestion, provided they meet the dosage and retail packaging requirements.
