2933.99.08.00 - Aceto acetyl-5-amino benz imidazolone; 3-(2H-Benzo triazol-2-yl)-5-(tert-butyl)-4- hydroxy benzene propanoic acid, C7-C9 branched or linear alkyl esters; 2-(2H-Benzotriazol-2-yl)-6-dodecyl-4- methyl phenol, in liquid form, branched and linear; and 1,3,3-Trimethyl-2-methyleneindoline

This HTS classification, 2933.99.08.00, encompasses a specific set of heterocyclic organic compounds containing nitrogen hetero-atoms. The described products include Aceto acetyl-5-amino benz imidazolone, various C7-C9 branched or linear alkyl esters of 3-(2H-Benzo triazol-2-yl)-5-(tert-butyl)-4- hydroxy benzene propanoic acid, liquid forms of branched and linear 2-(2H-Benzotriazol-2-yl)-6-dodecyl-4- methyl phenol, and 1,3,3-Trimethyl-2-methyleneindoline. These compounds are characterized by their aromatic or modified aromatic structures with nitrogen as the sole hetero-atom within the heterocyclic ring.

This particular subcategory is distinguished from its siblings by the specific chemical structures of the enumerated compounds. For instance, while other siblings might cover broader classes of aromatic or modified aromatic heterocyclic compounds such as indole or carbazole, 2933.99.08.00 focuses on a more granular selection defined by their unique functional groups and substitution patterns. Classification within this code relies on the precise identification of these chemical entities, often based on their CAS numbers or detailed structural analysis, to differentiate them from other "Other" heterocyclic compounds within subheading 2933.99.

As this classification represents a leaf node within the HTS, there are no further subdivisions. Therefore, the practical application of this code hinges on a direct match between the imported or exported product and the specific chemical substances listed in the description. The presence of these particular compounds, whether as single entities or mixtures in the specified forms (e.g., liquid), is the definitive criterion for classification under 2933.99.08.00.
