Products classified under HTS 2917.19.27.00
Adipic Acid Derivative (Dibutyl Adipate)
Dibutyl adipate, an ester derivative of adipic acid, used as a plasticizer in cosmetics and coatings. Falls under HTS 2917.19.27.00 as 'other derivatives' of adipic acid per the subheading scope and Chapter 29 ester classification rules.
Maleic Acid
Pure maleic acid, the dicarboxylic acid precursor to maleic anhydride, explicitly named in this HTS provision. Used in synthesis of unsaturated polyester resins and as a food additive.
Dimethyl Succinate
Dimethyl ester of succinic acid derived from maleic anhydride process. Solvent and intermediate in pharmaceuticals and polymers.
Monoisopropyl Maleate
Half-ester of maleic acid with isopropanol, used in reactive diluents for coatings.
Adipic Acid Peroxide
Peroxide derivative of adipic acid used as polymerization initiator.
Tetrabutyl Fumarate
Tetraester of fumaric acid from aromatic sources, plasticizer application.
Succinic Anhydride
Cyclic anhydride from maleic-derived succinic acid, resin intermediate.
Diethyl Glutarate
Diethyl ester of cyclopentanone-derived glutaric acid.
Maleic Acid Monobutyl Ester
Monoester derivative for surface treatments.
Glutaric Anhydride
Anhydride of cyclopentanone-derived glutaric acid.
Fumaric Acid Diamide
Diamide derivative of aromatic-derived fumaric acid.
Maleic Anhydride
Maleic anhydride is a cyclic anhydride derived from maleic acid, an acyclic polycarboxylic acid, used primarily in the production of resins and polymers. It falls under HTS 2917.19.27.00 as an anhydride of maleic acid, specifically listed in this subheading for derivatives not elsewhere specified. This chemical is a key intermediate in unsaturated polyester resins and alkyd coatings.
Succinic Acid from Maleic Anhydride
Succinic acid produced through hydrogenation of maleic anhydride, qualifying under the specific derivation clause in this HTS code. Used in biodegradable plastics, food additives, and pharmaceuticals. Classified here as a derivative of succinic acid sourced from maleic anhydride per Chapter 29 notes.
Glutaric Acid from Cyclopentanone
Glutaric acid produced via oxidation of cyclopentanone, explicitly covered in this HTS subheading. Utilized in polymer production and as a precursor for pharmaceuticals.
Fumaric Acid from Aromatic Hydrocarbons
Fumaric acid manufactured from aromatic hydrocarbon precursors like benzene via catalytic oxidation. Widely used in food as an acidulant and in resins; classified under this subheading due to specified derivation.
