Last updated: August 2026 dataThiophosphoric esters — organophosphorus compounds in which one or more oxygen atoms in the phosphate group are replaced by sulfur — are widely used as pesticide active ingredients (e.g., parathion-type insecticides) and as lubricant additives. The US schedule separates aromatic (2920194000) from non-aromatic (2920195000) members within this residual heading. Mexico leads US import supply, followed by Germany and China — a supplier mix that reflects both USMCA-advantaged chemical manufacturing in Mexico and established European and Asian specialty-chemical producers.

Yes. Thiophosphoric esters imported as pesticide active ingredients or formulated pesticides must be covered by a valid EPA registration under FIFRA. Shipments may be subject to EPA review at the port of entry, and the importer of record bears responsibility for ensuring registration and labeling compliance. Consult a licensed customs broker and regulatory counsel with EPA pesticide expertise before importing.
The aromatic designation applies when the thiophosphoric ester has one or more ester groups directly bonded to an aromatic ring system. Non-aromatic thiophosphoric esters, where all ester substituents are aliphatic or cycloaliphatic, fall under 2920195000. For compounds with ambiguous structures — such as mixed aryl-alkyl thiophosphates — the GRI classification rules and, if necessary, a CBP binding ruling should be used to confirm the correct 10-digit line.
