About HS Code 291739

This "not elsewhere specified" category covers a diverse range of aromatic polycarboxylic acids and their derivatives that do not fit into the more specific subheadings of 2917.3. These chemicals serve various niche applications as intermediates in the synthesis of polymers, pharmaceuticals, dyes, and specialty chemicals. Trade in these products is often characterized by smaller volumes compared to bulk chemicals like PTA or phthalic anhydride, but with higher value due to their specialized nature. Importers are typically specialized chemical manufacturers, research institutions, and pharmaceutical companies across developed and developing economies. Exporters are often fine chemical producers. Key aspects include high purity requirements, specific structural isomers, and compliance with diverse regulatory frameworks depending on their end-use, making detailed product identification crucial.

Products Under This Code

Isophthalic acid, Trimellitic anhydride, Pyromellitic dianhydride (PMDA), Benzene-1,2,4-tricarboxylic acid, Naphthalene dicarboxylic acid, Mellitic acid, Hemimellitic acid

Real World Examples

Sigma-Aldrich Isophthalic Acid, TCI Trimellitic Anhydride, Merck Pyromellitic Dianhydride, BASF Naphthalene Dicarboxylic Acid, Alfa Aesar Benzene-1,2,4-tricarboxylic acid

Common Misclassification

This code is a catch-all, so misclassification often occurs when a specific aromatic polycarboxylic acid *should* be classified under a more precise heading like 291734, 291735, 291736, or 291737, but is mistakenly placed here due to lack of detailed identification.
