Products classified under HTS 2917.19.40.00
Phthalic Anhydride
Phthalic anhydride is an acyclic polycarboxylic acid derivative produced by the oxidation of naphthalene or o-xylene, both aromatic hydrocarbons. It falls under HTS 2917.19.40.00 as it is derived in whole or in part from aromatic hydrocarbons and used primarily in plasticizers and resins. This classification applies to its pure chemical form meeting chapter 29 notes for separate chemically defined organic compounds.
Tetrahydrophthalic Anhydride
Tetrahydrophthalic anhydride is a hydrogenated derivative of phthalic anhydride, synthesized from aromatic precursors like o-xylene. Classified under HTS 2917.19.40.00 due to its partial aromatic hydrocarbon derivation and acyclic polycarboxylic acid anhydride structure. Used in epoxy resins and alkyd coatings.
Dimer Acid (Aromatic-Derived)
Dimer acids are high molecular weight acyclic dicarboxylic acids produced by dimerization of unsaturated fatty acids from aromatic petroleum fractions. Falls under HTS 2917.19.40.00 as acyclic polycarboxylic acids derived from aromatic hydrocarbons. Primarily used in polyamide hot melt adhesives.
Isophthalic Acid
Isophthalic acid (1,3-benzenedicarboxylic acid) is an acyclic polycarboxylic acid manufactured via oxidation of meta-xylene, an aromatic hydrocarbon. Classified in HTS 2917.19.40.00 due to its aromatic derivation and meeting Chapter 29 purity requirements. Key raw material for PET resins and coatings.
Aromatic Azelaic Acid Derivative
Azelaic acid derivatives produced via oxidative cleavage of aromatic oleic acid fractions, qualifying as acyclic nonanedioic acids from aromatic sources. HTS 2917.19.40.00 applies per derivation requirement and polycarboxylic acid structure. Used in pharmaceuticals and polymers.
Branched Aromatic Dicarboxylic Acid
Branched chain dicarboxylic acids synthesized from alkylated aromatic hydrocarbons via air oxidation processes. Meets HTS 2917.19.40.00 as acyclic polycarboxylic acids with documented aromatic derivation. Applications include specialty polyester production.
