Products classified under HTS 2907.23.00.00
Bisphenol A (BPA)
4,4'-Isopropylidenediphenol, commonly known as Bisphenol A, is a synthetic organic compound used primarily in the production of polycarbonate plastics and epoxy resins. It falls under HTS 2907.23.00.00 as a specific polyphenolic compound matching the chemical description of 4,4'-Isopropylidenediphenol and its salts. This white crystalline solid is a key industrial intermediate.
Bisphenol A Technical Grade 99%
Technical grade Bisphenol A with 99% purity is a high-volume industrial chemical used in manufacturing polycarbonate sheets and epoxy coatings. Classified under HTS 2907.23.00.00 due to its chemical identity as 4,4'-Isopropylidenediphenol meeting chapter note (a) for separate chemically defined compounds. Supplied as free-flowing white powder in bulk packaging.
Sodium Salt of Bisphenol A
The sodium salt form of 4,4'-Isopropylidenediphenol (Bisphenol A sodium salt) is explicitly covered under HTS 2907.23.00.00 per the subheading description 'and its salts.' This water-soluble variant serves as an intermediate in specialty resin synthesis and analytical chemistry applications.
High-Purity Bisphenol A for Polycarbonate
Ultra-high purity (99.9%+) Bisphenol A specifically produced for optical-grade polycarbonate manufacturing. Classified under HTS 2907.23.00.00 as chemically defined 4,4'-Isopropylidenediphenol per chapter note (a). Minimizes discoloration in transparent plastic applications.
Bisphenol A with Stabilizer
Bisphenol A containing added oxidation stabilizer for extended shelf life during transport, permitted under chapter note (f). Still classified as HTS 2907.23.00.00 since stabilizer necessary for preservation and maintains general use character. Used in composite materials production.
Diphenylolpropane (BPA Alternative Name)
Diphenylolpropane, the systematic name for 4,4'-Isopropylidenediphenol (Bisphenol A), used interchangeably in technical specifications. Directly matches HTS 2907.23.00.00 subheading nomenclature for import declarations. Essential monomer for engineering thermoplastics.
Bisphenol A Flake Form
Bisphenol A supplied in solid flake form for easy melting and processing in epoxy resin production lines. Falls squarely under HTS 2907.23.00.00 as the pure chemical compound 4,4'-Isopropylidenediphenol without excluded additives. Commonly used in can coatings and adhesives.
