Bisphenol A (BPA)
Bisphenol A (BPA), also known as 4,4'-Isopropylidenediphenol, is a synthetic organic compound primarily used in the production of polycarbonate plastics and epoxy resins. It is a separate chemically defined organic compound, falling under tariff item 2907.23.00 as specified in the Customs Tariff of Canada.
Bisphenol A Flake Form
Bisphenol A in flake form is the same chemical compound, 4,4'-Isopropylidenediphenol, presented as solid flakes for ease of handling in epoxy resin production. The physical form does not alter its classification under tariff item 2907.23.00, as it remains a separate chemically defined organic compound.
Bisphenol A Technical Grade 99%
Technical grade Bisphenol A with 99% purity is 4,4'-Isopropylidenediphenol, a high-volume industrial chemical used in polycarbonate sheets and epoxy coatings. It qualifies as a separate chemically defined organic compound under chapter note 1(a), even with minor impurities, and is classified under tariff item 2907.23.00.
Bisphenol A with Stabilizer
Bisphenol A with added oxidation stabilizer is still 4,4'-Isopropylidenediphenol, where the stabilizer is necessary for preservation during transport. Under chapter note 1(f), such additions do not change classification, so it remains under tariff item 2907.23.00.
Diphenylolpropane (BPA Alternative Name)
Diphenylolpropane is an alternative name for 4,4'-Isopropylidenediphenol, also known as Bisphenol A. The product is the same chemical compound, and its classification under tariff item 2907.23.00 is based on its chemical identity, not the name used in documentation.
High-Purity Bisphenol A for Polycarbonate
High-purity Bisphenol A at 99.9% purity is 4,4'-Isopropylidenediphenol, produced for optical-grade polycarbonate manufacturing. As a separate chemically defined organic compound, it is classified under tariff item 2907.23.00, with purity not affecting its tariff classification.
Sodium Salt of Bisphenol A
Sodium salt of Bisphenol A is a salt of 4,4'-Isopropylidenediphenol, explicitly covered by the tariff item description 'and its salts.' It is classified under tariff item 2907.23.00, as salts of the specified compound are included in the subheading.
