2939.41.00.00 - Ephedrine and its salts

This HTS category, 2939.41.00.00, specifically covers ephedrine and its salts. Ephedrine is an alkaloid derived from plants of the *Ephedra* genus or synthesized chemically, known for its stimulant and bronchodilator properties. Its salts, formed by combining ephedrine with an acid, are also included under this classification. This designation is crucial for goods that are primarily ephedrine or its direct salt derivatives, irrespective of their specific salt form (e.g., hydrochloride, sulfate).

Distinguishing this category from its siblings is essential for accurate classification. While all are alkaloids of ephedra and their derivatives, 2939.41.00.00 is exclusively for ephedrine and its salts. It differentiates from pseudoephedrine (2939.42.00.00), cathine (2939.43.00.00), norephedrine (2939.44.00.00), and the various forms of metamfetamine and its salts (2939.45.00.00) by focusing on the specific chemical structure and identity of ephedrine. The "Other" category (2939.49.03.00) serves as a residual classification for any other ephedra alkaloid derivatives not specifically listed.

As this HTS code represents a leaf node within the tariff schedule, there are no further subcategories. The classification is definitive for ephedrine and its salts. When classifying goods, particular attention should be paid to the precise chemical name and form of the substance to ensure it falls within this specific category rather than a related one. For instance, mixtures containing ephedrine may be classified elsewhere depending on the principal constituent or intended use, subject to general interpretative rules.
