3003.43.00.00 - Containing norephedrine or its salts

This HTS classification covers medicaments that contain norephedrine or its salts, specifically when these substances are mixed with other medicinal ingredients for therapeutic or prophylactic purposes. These products are not intended for direct consumer use in measured doses or retail packaging. The scope of this heading is limited to mixtures that are not specifically classified elsewhere, such as in headings 3002, 3005, or 3006.

Distinguishing this category from its siblings is crucial for accurate classification. HTS code 3003.43.00.00 specifically addresses medicaments containing norephedrine. It differentiates itself from 3003.41.00.00, which covers ephedrine and its salts, and 3003.42.00.00, which pertains to pseudoephedrine (INN) and its salts. Any other alkaloid-containing medicament mixtures not falling under these specific distinctions would be classified under the residual category 3003.49.00.00.

As a leaf node, 3003.43.00.00 does not have further subcategories. Therefore, the focus remains on the precise identification of norephedrine or its salts as the key active constituent within a mixed medicinal product. Examples would include bulk pharmaceutical preparations intended for further processing into finished dosage forms, where the presence of norephedrine is a defining characteristic for classification.
