2915.90.20.00 - Aromatic

This HTS category, 2915.90.20.00, specifically covers aromatic saturated acyclic monocarboxylic acids and their derivatives, including anhydrides, halides, peroxides, and peroxyacids, as well as their halogenated, sulfonated, nitrated, or nitrosated forms. The defining characteristic of products within this subcategory is the presence of an aromatic ring structure within their chemical composition, in addition to the saturated acyclic monocarboxylic acid functional group. Examples may include derivatives of benzoic acid or cinnamic acid that meet the saturated acyclic monocarboxylic acid criteria.

This classification is distinguished from its sibling, 2915.90.50, which covers "Other" saturated acyclic monocarboxylic acids and their derivatives that do *not* possess an aromatic component. Therefore, if the compound in question contains an aromatic group, it would fall under 2915.90.20.00, whereas purely aliphatic compounds would be classified elsewhere.

As a leaf node, this category does not have further subcategories. The classification of goods within 2915.90.20.00 relies on confirming the presence of both the aromatic functionality and the saturated acyclic monocarboxylic acid structure, along with any specified derivatives or modifications. This precise definition ensures accurate tariff application for a range of specialized organic chemicals.
