2902.41.00.00 - o-Xylene

This HTS classification, 2902.41.00.00, specifically covers ortho-xylene (o-xylene). Ortho-xylene is an aromatic hydrocarbon with the chemical formula C8H10, characterized by two methyl groups attached to adjacent carbon atoms on a benzene ring. It is a colorless, flammable liquid with a characteristic sweet odor and is primarily used as a solvent and as an intermediate in the production of various chemicals, most notably phthalic anhydride.

Distinguishing this category from its siblings is crucial for accurate classification. While 2902.42.00.00 pertains to meta-xylene (m-xylene) and 2902.43.00.00 to para-xylene (p-xylene), both of which have methyl groups in different positions on the benzene ring, 2902.41.00.00 exclusively identifies the isomer where these groups are adjacent. Mixed xylene isomers, classified under 2902.44.00.00, encompass mixtures of ortho-, meta-, and para-xylenes in varying proportions, lacking the specific isolation of the ortho-isomer.

As a leaf node within the HTS structure, this classification does not have further subcategories. Therefore, the focus for classification remains on the precise identification of ortho-xylene itself, differentiating it from its structural isomers based on positional isomerism of the methyl groups on the benzene ring and from mixtures thereof. Accurate identification relies on chemical analysis or supplier declarations specifying the singular ortho-isomer.
