2939.43.00.00 - Cathine (INN) and its salts

This HTS classification covers cathine, also known by its International Nonproprietary Name (INN), and its various salts. Cathine is an alkaloid with stimulant properties, naturally found in the Khat plant (*Catha edulis*). Its salts are inorganic or organic compounds formed by reacting cathine with an acid, often to improve stability, solubility, or ease of administration.

This category is specifically dedicated to cathine and its salts, differentiating it from its sibling HTS codes. For instance, HTS 2939.41.00.00 covers ephedrine and its salts, while 2939.42.00.00 addresses pseudoephedrine and its salts. Other siblings, such as those for norephedrine and metamfetamine, further refine the classification based on the specific chemical structure of related alkaloids. This precise distinction is crucial for accurate customs declarations and trade compliance.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 2939.43.00.00 relies on definitively identifying the substance as cathine or a salt thereof. It is important to consult analytical data, product specifications, or laboratory testing to confirm the identity of the imported or exported material, ensuring it aligns with the chemical definition of cathine or its salts.
