Xylene

Mixed xylenes (a blend of ortho-, meta-, and para-xylene plus ethylbenzene) are typically used as solvents or gasoline blendstocks and trade at lower values than isolated isomers. High-purity paraxylene (PX), separated by crystallization or adsorption, commands a significant premium as the feedstock for PTA and polyester production. Importers should specify isomer composition and purity on the commercial invoice and certificate of analysis to support accurate classification and pricing.

Trade remedy exposure for xylene depends on the specific product form and country of origin. Importers should conduct a current antidumping and countervailing duty scope review with a licensed customs broker before committing to supply contracts, as the petrochemical sector has historically been subject to trade remedy investigations that can change duty exposure materially.
