Overview

This HTS category specifically classifies Fenetylline (identified by its International Nonproprietary Name - INN) and any salts derived from it. Fenetylline is a synthetic stimulant drug that combines the effects of amphetamine and theophylline. Its classification under this heading is based on its distinct chemical structure as a derivative of alkaloids.

This category is distinguished from its sibling, 2939.59.00.00, which covers "Other" alkaloids, natural or synthesized, and their derivatives, that do not specifically fall under the more defined categories within heading 2939.5. Therefore, any compound fitting the description of Fenetylline and its salts would be classified here, while other miscellaneous alkaloid derivatives would fall into the "Other" category.

As this is a leaf node in the HTS structure, there are no further subcategories for this specific classification. Classification decisions will rely on accurately identifying the substance as Fenetylline or its salts, based on chemical analysis and product documentation, and ensuring it is not classifiable under a more general provision.
