2707.30.00.20 - o-Xylene 🖩

This classification covers ortho-xylene (o-xylene), a specific isomer of xylene. It falls under the broader category of xylenes, which are aromatic hydrocarbons derived from the distillation of high-temperature coal tar or similar processes where aromatic constituents outweigh non-aromatic ones. O-xylene is a colorless, flammable liquid with a characteristic sweet odor, primarily used as a solvent and as a precursor in the production of other chemicals, most notably phthalic anhydride.

Distinguishing o-xylene from its sibling categories is crucial for accurate classification. While 2707.30.00.10 specifically denotes m-xylene and 2707.30.00.30 denotes p-xylene, this code is reserved for o-xylene. The "Other" category (2707.30.00.40) serves as a residual classification for any xylenes that do not fit the definitions of ortho-, meta-, or para-xylene individually. The primary differentiator between these xylenes is the relative position of the two methyl groups on the benzene ring, which affects their physical and chemical properties.

As a leaf node, this HTS classification does not have further subcategories. Therefore, classification under 2707.30.00.20 is determined by the product being definitively identified as o-xylene, separate from its structural isomers m-xylene and p-xylene. Importers and exporters should ensure their documentation clearly identifies the specific xylene isomer being shipped to comply with customs regulations.
