2915.60.10.00 - Aromatic

This HTS category, 2915.60.10.00, specifically covers aromatic butanoic acids, pentanoic acids, and their salts and esters. These are organic compounds characterized by the presence of both a carboxylic acid functional group (within the butanoic or pentanoic acid structure) and an aromatic ring system attached to the carbon chain. The "aromatic" designation is the key differentiator, signifying that the molecule incorporates a benzene ring or a similar cyclic, delocalized pi-electron system. Examples might include phenylbutanoic acid or its derivatives.

The primary distinction for this category lies in its "aromatic" nature, differentiating it from other classifications within 2915.60 that are not explicitly aromatic. This means that while other butanoic and pentanoic acid derivatives might be covered elsewhere in the tariff, those with an aromatic component are specifically addressed here.

As this is a leaf node, there are no further subcategories. Therefore, classification into this code hinges on the precise chemical structure of the imported or exported substance, confirming the presence of an aromatic moiety in conjunction with the butanoic or pentanoic acid structure. The absence of further subdivisions emphasizes the specific focus of this code on this particular group of aromatic carboxylic acid derivatives.
