Products classified under HTS 2920.19.40.00
O,O-Diethyl S-(2-chlorophenyl) phosphorothioate
This aromatic thiophosphoric ester, known as Tolylfluanid intermediate, is a phosphorodithioate derivative used in pesticide synthesis. It falls under HTS 2920.19.40.00 as an 'other' aromatic thiophosphoric ester with halogenated substitution on the phenyl ring. The chemical structure features phosphorus-sulfur bonds characteristic of this subheading.
Triphenyl phosphorothioate
A trisubstituted aromatic thiophosphoric ester used as a flame retardant additive and lubricant extreme pressure agent. Classified under HTS 2920.19.40.00 as an 'other' aromatic phosphorodithioate with three phenyl groups. Meets chapter 29 criteria for separate chemically defined organic phosphorus compounds.
O,O-Dimethyl S-phenyl phosphorothioate
Simple aromatic phosphorodithioate ester serving as intermediate for insecticide synthesis and analytical standards. Falls under HTS 2920.19.40.00 as 'other' aromatic thiophosphoric ester without additional heteroatoms. The phenyl-thiophosphoryl structure defines its chapter 29 classification.
Cresyl diphenyl phosphorothioate
Mixed aryl thiophosphoric ester used in hydraulic fluids and as antioxidant in petroleum additives. HTS 2920.19.40.00 classification applies to this aromatic 'other' phosphorodithioate with cresyl (methylphenyl) substitution. Exceeds purity threshold for separate chemical compound status.
O-Ethyl O-(4-nitrophenyl) phosphorothioate
Nitrosated aromatic thiophosphoric ester used in pharmaceutical intermediate synthesis and as analytical reagent. Classified HTS 2920.19.40.00 due to nitro-substituted phenyl ring on phosphorodithioate core. Chapter notes explicitly include nitrated derivatives in this heading.
Diphenyl phosphorochloridothioate
Aromatic thiophosphoric ester chloride intermediate for agricultural chemical synthesis. HTS 2920.19.40.00 covers this 'other' bis-aryl phosphorodithioate derivative. Acid halide functionality remains classified with parent thiophosphoric acid ester per chapter note (E).
O,O-Diethyl S-(4-methylphenyl) phosphorothioate
Para-tolyl substituted aromatic phosphorodithioate used in acaricide formulations. Falls under HTS 2920.19.40.00 as 'other' thiophosphoric ester with methyl-substituted phenyl ring. Chemically defined structure excludes mixture classification.
Phenoxyphenyl phosphorothioate
Complex aromatic thiophosphoric ester featuring ether-linked phenyl rings, used in specialty polymer additives. HTS 2920.19.40.00 applies to this multi-ring 'other' phosphorodithioate. Principal characteristic group remains P-S ester functionality.
Bis(4-chlorophenyl) phosphorothioate
Di-chlorinated aromatic thiophosphoric ester used as synthetic intermediate and flame retardant. Classified HTS 2920.19.40.00 as halogenated 'other' aromatic phosphorodithioate. Dual phenyl substitution maintains chemical definition status.
O-Phenyl O-(2-naphthyl) phosphorothioate
Polycyclic aromatic thiophosphoric ester for UV stabilizer applications in plastics. HTS 2920.19.40.00 covers this naphthyl-phenyl 'other' phosphorodithioate derivative. Naphthalene substitution qualifies as aromatic per tariff definition.
