2939.20.00.10 - Quinine and its salts

This HTS category, 2939.20.00.10, specifically covers quinine and its various salts. Quinine is a naturally occurring alkaloid derived from the bark of cinchona trees, historically recognized for its antimalarial properties and also used in tonic water for its bitter taste. This classification extends to any chemical salts formed with quinine, such as quinine sulfate or quinine hydrochloride, which are often used in pharmaceutical preparations or as analytical reagents.

It is important to distinguish this specific classification from its sibling category, 2939.20.00.50, which encompasses "Other" alkaloids of cinchona and their derivatives. While 2939.20.00.10 is exclusively for quinine and its salts, the "Other" category would include different cinchona alkaloids like quinidine, cinchonine, and cinchonidine, as well as any synthesized derivatives or salts not directly related to quinine.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification within 2939.20.00.10 is determined solely by whether the product is identified as quinine or a salt thereof, derived from cinchona bark or synthesized. The focus for classification purposes will be on chemical identification and the presence of quinine as the principal alkaloid or as a salt.
