2924.24.00.00 - Ethinamate (INN)

This HTS category, 2924.24.00.00, specifically classifies Ethinamate (INN), a pharmaceutical intermediate or active ingredient. It falls under the broader grouping of cyclic amides and their derivatives, which are organic compounds featuring a cyclic structure with an amide functional group. The inclusion of "cyclic carbamates" in the parent category indicates a broader scope for this level, encompassing related structures where the carbonyl group of the amide is part of a carbamate ester.

Within the section for cyclic amides, this particular HTS code stands apart from its siblings. Unlike 2924.21 which covers ureines and their derivatives, or 2924.23 which is reserved for 2-Acetamidobenzoic acid, this code is precisely designated for Ethinamate. It also differs from 2924.25.00.00, which classifies the specific herbicide Alachlor, and the residual category 2924.29 which serves as a catch-all for other cyclic amides not elsewhere specified. The specificity of 2924.24.00.00 highlights the importance of chemical identity in tariff classification.

As this HTS code represents a leaf node, there are no further subcategories. Classification at this level is definitive for Ethinamate, requiring no further subdivision. Customs professionals should ensure that the goods being declared precisely match the chemical identity and common name (INN) of Ethinamate to ensure correct classification under this specific code.
