2916.39.16.00 - 4-Chlorobenzoic acid

This classification, HTS Code 2916.39.16.00, specifically covers 4-Chlorobenzoic acid. This compound is an aromatic monocarboxylic acid, characterized by the presence of a chlorine atom at the para position of the benzoic acid ring. Its chemical structure dictates its properties and applications, which are distinct from other related aromatic benzoic acid derivatives.

Within the broader category of "Other" aromatic monocarboxylic acids and their derivatives, 4-Chlorobenzoic acid is differentiated from its siblings by its precise chemical structure and the specific position of the chlorine substituent. For instance, while other entries might include different nitro or sulfonic acid substituted benzoic acids, or even anhydrides and esters, this code is solely dedicated to the identified 4-Chlorobenzoic acid.

As this is a leaf node within the HTS, there are no further subcategories under 2916.39.16.00. Therefore, classification under this code is definitive for 4-Chlorobenzoic acid. Importers and exporters should ensure that the chemical substance they are declaring precisely matches the chemical identity of 4-Chlorobenzoic acid to avoid misclassification, as minor structural variations would necessitate classification under a different HTS code.
