Products classified under HTS 2920.30.00.00
Endosulfan Technical Grade 95%
Endosulfan Technical Grade 95% is a pure chemical formulation of the organochlorine insecticide Endosulfan (ISO), consisting primarily of alpha and beta isomers in a specific ratio. It falls under HTS 2920.30.00.00 as it is the specific compound explicitly named in the heading for esters of inorganic acids of nonmetals. This product is used as the base material for manufacturing formulated pesticides.
Endosulfan Alpha Isomer 99%
Endosulfan Alpha Isomer 99% is a highly purified single isomer of endosulfan (ISO), separated for research and specialized applications. Classified under HTS 2920.30.00.00 as it matches the chemical definition of endosulfan in the tariff heading for organo-inorganic compounds. Used in analytical standards and synthesis.
Endosulfan Beta Isomer Standard
Endosulfan Beta Isomer Standard is a reference material containing the beta isomer of endosulfan (ISO) at certified concentration for calibration purposes. It qualifies under HTS 2920.30.00.00 as the named compound in pure or stabilized form per chapter notes. Primarily used in environmental and pesticide residue testing laboratories.
Endosulfan Sulfate Metabolite 98%
Endosulfan Sulfate Metabolite 98% is the primary degradation product of endosulfan (ISO), chemically related as its sulfate ester derivative. Falls under HTS 2920.30.00.00 when imported as the reference standard matching the parent compound's classification. Used in toxicology studies and environmental monitoring.
Endosulfan Reference Standard USP
Endosulfan Reference Standard USP is a pharmacopeia-grade certified reference material of endosulfan (ISO) for analytical method validation. Classified precisely under HTS 2920.30.00.00 as the pure, chemically defined compound named in the heading. Essential for quality control in residue analysis.
Endosulfan 35% EC Emulsifiable Concentrate
While typically under 3808, pure endosulfan component separated from formulation may be classified here when imported for local formulation. However, strictly under HTS 2920.30.00.00 only if qualifying as pure compound per chapter notes excluding mixtures. Note: Primarily 3808 product.
