Products classified under HTS 2917.19.20.00
Maleic Anhydride
Maleic anhydride is a cyclic anhydride derived from maleic acid, used primarily in the production of resins, coatings, and agricultural chemicals. It falls under HTS 2917.19.20.00 as an anhydride of maleic acid, specifically listed in additional U.S. note 3 to section VI for polycarboxylic acid derivatives.
Succinic Acid from Maleic Anhydride
Succinic acid produced through hydrogenation of maleic anhydride, used in biodegradable plastics, pharmaceuticals, and food additives. Classified under HTS 2917.19.20.00 as succinic acid derived in whole or in part from maleic anhydride per the heading description.
Fumaric Acid from Aromatics
Fumaric acid produced from aromatic hydrocarbons via catalytic oxidation, primarily used as an acidulant in food/beverage and in polyester resins. Falls under HTS 2917.19.20.00 as fumaric acid derived in whole or in part from aromatic hydrocarbons.
Adipic Acid Peroxide Derivative
Di(1-hydroperoxy-1-methylbutyl) peroxide, a peroxyacid derivative of adipic acid used as polymerization initiator in rubber and plastics. Specifically included under HTS 2917.19.20.00 for peroxyacids and derivatives of adipic acid.
Maleic Acid
Maleic acid, the dicarboxylic acid isomer of fumaric acid, used in epoxy resins, coatings, and agricultural chemicals. Directly listed under HTS 2917.19.20.00 as a specified acyclic polycarboxylic acid.
Glutaric Acid from Cyclopentanone
Glutaric acid produced via oxidative cleavage of cyclopentanone, used in pharmaceuticals, polymers, and corrosion inhibitors. Classified under HTS 2917.19.20.00 for glutaric acid derived from cyclopentanone.
Dibutyl Maleate
Dibutyl maleate, an ester of maleic acid with butanol, used as reactive diluent in unsaturated polyester resins and copolymer production. Falls under HTS 2917.19.20.00 per chapter note on ester classification with parent acid.
Succinic Anhydride
Succinic anhydride derived from maleic anhydride via hydrogenation and dehydration, used in pharmaceutical intermediates and performance chemicals. Included in HTS 2917.19.20.00 for anhydrides of specified succinic acid sources.
