2924.29.23.00 - 4-Amino acetanilide; 2,2'-Oxamido bis [ethyl-3-(3,5-di-tert-butyl- 4-hydroxyphenyl) propionate]; Aceto acetsulfanilic acid, potassium salt; and N-(2,3-Dihydroxy propyl)-5-N-(2,3-dihydroxy- propyl) acetamido-N'-(2-hydroxyethyl)- 2,4,6-triiodoisophthalamide 🖩

This HTS classification covers a specific group of aromatic carboxyamide-function compounds and related amide-function compounds of carbonic acid that do not fall under more specifically defined sibling categories. It includes compounds such as 4-Amino acetanilide, 2,2'-Oxamido bis [ethyl-3-(3,5-di-tert-butyl- 4-hydroxyphenyl) propionate], Aceto acetsulfanilic acid, potassium salt, and N-(2,3-Dihydroxy propyl)-5-N-(2,3-dihydroxy- propyl) acetamido-N'-(2-hydroxyethyl)- 2,4,6-triiodoisophthalamide. These substances are characterized by the presence of an amide group attached to an aromatic ring and possess unique chemical structures and applications.

Distinguishing this category from its siblings involves a detailed examination of the chemical structure and the specific substituents present. While other sibling categories might cover simpler acetanilides or compounds with different functional groups, this heading is reserved for the more complex structures listed in its description. For instance, sibling entries may focus on compounds with specific dye intermediates or less complex aromatic amides, whereas this heading captures specialized chemical entities based on their precise molecular arrangement.

As this node represents a leaf node in the HTS classification, there are no further subdivisions. Classification within this heading relies entirely on the accurate identification of the imported goods with the specific chemical names provided in the description. Importers must ensure their goods precisely match one of the listed substances to ensure correct classification and avoid potential discrepancies during customs clearance.
