Overview
HTS Code 2917.39.08.00 specifically classifies Naphthalic anhydride. This compound is an organic chemical belonging to the broader category of aromatic polycarboxylic acids and their derivatives. Naphthalic anhydride is characterized by its fused ring structure derived from naphthalene, featuring an anhydride functional group. Its primary use is as an intermediate in the synthesis of dyes, pigments, and agricultural chemicals.
This classification distinguishes Naphthalic anhydride from its siblings, such as 1,2,4-Benzenetricarboxylic acid, 1,2-dianhydride (Trimellitic anhydride) and Phthalic acid, which are benzene-based. It also differs from specialized derivatives like 4,4'-(Hexafluoroisopropylidene)bis(phthalic anhydride) and Tetrabromophthalic anhydride, which contain specific halogen substituents. Furthermore, it is distinct from Isophthalic acid, which is a monocyclic aromatic dicarboxylic acid.
As a leaf node within the HTS system, 2917.39.08.00 does not have further subdivisions. Therefore, the classification hinges on the precise identification of Naphthalic anhydride itself, based on its chemical structure and properties, differentiating it from other "Other" aromatic polycarboxylic acid anhydrides and their derivatives that fall under broader HTS codes.
