Products classified under HTS 2903.89.31.00
Chlordane Technical Grade
Chlordane is a chlorinated cyclodiene insecticide derived from cyclanic hydrocarbons, featuring multiple chlorine atoms but no other halogens. It falls under HTS 2903.89.31.00 as a halogenated derivative of cyclanic hydrocarbons that is chlorinated but not otherwise halogenated. Primarily used in agricultural pest control formulations.
Endosulfan Isomer Mixture
Endosulfan consists of alpha and beta isomers, chlorinated derivatives of cyclanic hydrocarbons used as insecticides. Classified under HTS 2903.89.31.00 for its chlorinated cyclodiene structure without other halogens. Restricted due to environmental persistence concerns.
Dieldrin Pure Compound
Dieldrin is an epoxidized chlorinated derivative of cyclanic hydrocarbons, used historically as a persistent insecticide. It qualifies for HTS 2903.89.31.00 due to chlorination of its cyclodiene structure without additional halogens. Highly regulated under Stockholm Convention.
Aldrin Technical Material
Aldrin is a pure chlorinated cyclodiene compound that oxidizes to dieldrin in environment, used as insecticide precursor. Falls under HTS 2903.89.31.00 as chlorinated derivative of cyclanic hydrocarbons. Technical grade contains 95%+ active ingredient.
Isodrin Chemical Standard
Isodrin serves as reference standard for analytical chemistry, a chlorinated cyclodiene hydrocarbon derivative. Classified under HTS 2903.89.31.00 for its specific chlorination pattern on cyclanic structure. Used in pesticide residue analysis.
Chlorinated Camphene (Toxaphene)
Toxaphene comprises chlorinated camphene mixture (67-69% chlorine), derived from bicyclic cycloterpenic hydrocarbon. HTS 2903.89.31.00 covers its chlorinated but not polyhalogenated nature. Banned insecticide with ongoing remediation uses.
Heptachlor Pure Isomer
Heptachlor features seven chlorine atoms on cyclodiene ring system, pure isomer for chemical synthesis. Classified HTS 2903.89.31.00 as chlorinated cyclanic derivative without other halogens. Precursor to heptachlor epoxide.
Chlorinated Bornane Derivatives
Chlorinated bornanes are bicyclic monoterpenoid derivatives with chlorine substitution, used in synthetic chemistry. HTS 2903.89.31.00 applies to these cycloterpenic hydrocarbon halogenated derivatives. Research intermediates for pharmaceuticals.
Lindane Gamma Isomer
Lindane is the pure gamma isomer of hexachlorocyclohexane (HCH), a chlorinated cyclanic derivative. Classifies under HTS 2903.89.31.00 despite six chlorines, as it's chlorinated-only substitution. Used in pharmaceutical scabicides.
Mirex Research Grade
Mirex is perchlorinated cyclopentadiene dimer, fully chlorinated cyclanic structure for research. HTS 2903.89.31.00 covers this chlorinated hydrocarbon without other halogens. Flame retardant and insecticide research applications.
