2902.43.00.00 - p-Xylene 🖩

This HTS category, 2902.43.00.00, specifically covers p-Xylene. P-Xylene is a pure isomer of xylene, a colorless, flammable liquid aromatic hydrocarbon. It is distinguished by the placement of its two methyl groups on opposite (para) positions of the benzene ring. Its primary commercial use is as a feedstock for the production of terephthalic acid, a key component in the manufacture of polyester fibers and films.

This classification is distinct from its sibling categories, which cover other isomers and mixtures of xylene. Specifically, 2902.41.00.00 pertains to o-Xylene (ortho-xylene), where methyl groups are adjacent, and 2902.42.00.00 covers m-Xylene (meta-xylene), where methyl groups are separated by one carbon atom. Mixed xylene isomers, encompassing various proportions of ortho-, meta-, and para-xylenes, are classified under 2902.44.00.00. Therefore, accurate classification hinges on the precise isomeric composition of the xylene.

As a leaf node within the HTS system, 2902.43.00.00 does not have further subdivisions. Classification at this level relies on the identification of the substance as p-Xylene, with its characteristic chemical structure and primary industrial applications serving as key discriminators. Importers and exporters should ensure their documentation clearly specifies the nature of the xylene being declared to comply with customs regulations.
