2916.12.10.00 - Aromatic

This category encompasses aromatic monocarboxylic acids and their derivatives, excluding those specifically classified elsewhere. It covers compounds characterized by the presence of a carboxyl group (-COOH) directly attached to an aromatic ring, such as benzoic acid, salicylic acid, and their various esters, amides, and salts. The "aromatic" qualifier is crucial, distinguishing these from their acyclic and cyclic aliphatic counterparts covered in preceding headings.

Within this level, the primary distinction lies between aromatic compounds and other types of unsaturated acyclic monocarboxylic acids and their derivatives, as well as cyclic monocarboxylic acids. This heading specifically targets compounds where the aromatic structure is a defining feature of the molecule, influencing its chemical properties and reactivity.

As this is a leaf node, there are no further subcategories. Therefore, classification within 2916.12.10.00 relies on a precise identification of the chemical structure as an aromatic monocarboxylic acid derivative. Examples include esters of benzoic acid, such as methyl benzoate, or derivatives of other aromatic carboxylic acids. The absence of halogenation, sulfonation, nitration, or nitrosation is implied by the specific HTS code.
