Products classified under HTS 2920.11.00.00
Parathion Technical Grade 95%
Parathion (ISO) is a highly toxic organophosphate insecticide classified under HTS 2920.11.00.00 as a thiophosphoric ester (phosphorodithioate). This technical grade concentrate contains 95% pure parathion and is used as the active ingredient for formulating agricultural pesticides.
Parathion-Methyl (Methyl Parathion) 97% TC
Methyl-parathion (ISO), also known as parathion-methyl, is the methyl ester analog of parathion specifically named in HTS 2920.11.00.00. This 97% technical concentrate is the primary form imported for emulsifiable concentrate formulations used on cotton and rice crops.
Methyl Parathion High Purity Reference Standard
USP/EP grade methyl-parathion at 99%+ purity used as analytical reference standard for pesticide residue testing and quality control. Classified under HTS 2920.11.00.00 as the pure thiophosphoric ester despite laboratory use designation.
Parathion Anhydrous Liquid 98%
Water-free parathion liquid at 98% concentration stabilized with epichlorohydrin, imported in bulk for high-purity emulsifiable concentrate production. HTS 2920.11.00.00 classification applies to this pure thiophosphoric ester form.
Parathion-Methyl Sodium Salt Solution 50%
Aqueous solution of parathion-methyl sodium salt at 50% active ingredient, classified under HTS 2920.11.00.00 per Chapter 29 note (C)(1) for inorganic salts of organic compounds. Used in water-based pesticide formulations.
Parathion 80% Wettable Powder Technical
Parathion technical material pre-dispersed on 80% concentration in wettable powder form for easier formulation, but still classified under HTS 2920.11.00.00 as the pure chemical compound. Used primarily for manufacturing dusts and water-dispersible granules.
