2924.29.77.20 - Acetoacet-2,5-dimethoxy-4- chloroanilide

This HTS classification, 2924.29.77.20, specifically covers Acetoacet-2,5-dimethoxy-4-chloroanilide. This compound falls within the broader category of carboxyamide-function compounds and amide-function compounds of carbonic acid, further refined to cyclic amides and their derivatives. Its precise structure, featuring an acetoacetyl group attached to a substituted anilide ring with dimethoxy and chloro substituents, is the defining characteristic for its placement at this detailed level.

The key differentiator for this code, compared to its siblings, lies in its specific chemical structure. While 2924.29.77.10 covers the simpler Acetoacetanilide, this code is reserved for the more complex derivative with the additional methoxy and chloro groups on the aromatic ring. Similarly, 2924.29.77.30 covers p-Aminobenzamide, a different functional group and structural arrangement entirely. The residual category, 2924.29.77.90, serves as a catch-all for other aromatic cyclic amides not otherwise specified.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the classification of Acetoacet-2,5-dimethoxy-4-chloroanilide is definitive at this level. Importers and exporters should ensure that the chemical identity and composition precisely match the description to ensure correct classification, utilizing laboratory analysis if necessary to confirm the presence and position of the dimethoxy and chloro substituents on the anilide ring.
