Products classified under HTS 2908.19.25.00
Tetrabromobisphenol A (TBBA)
Tetrabromobisphenol A is a brominated flame retardant chemically defined as 2,2',6,6'-tetrabromo-4,4'-isopropylidenediphenol, a halogenated derivative of phenols containing only bromine substituents. It falls under HTS 2908.19.25.00 as a specific derivative of phenols or phenol-alcohols with exclusively halogen substitution. Primarily used in plastics and electronics manufacturing for fire safety.
Tetrabromobisphenol A Technical Grade 99%
Technical grade Tetrabromobisphenol A with 99% purity is a white to off-white powder used as a reactive flame retardant in epoxy resins for printed circuit boards. Classified under HTS 2908.19.25.00 as it matches the chemical definition of a halogen-only substituted phenol derivative, even with minor impurities allowed by Chapter 29 notes. Essential for electronics industry fire retardancy.
TBBA Flame Retardant Powder (CAS 79-94-7)
TBBA identified by CAS number 79-94-7 is a high-melting-point (≥240°C) brominated bisphenol used in ABS plastics and polycarbonate composites for flame retardancy. It qualifies for HTS 2908.19.25.00 as a chemically defined organic compound that is a purely halogenated derivative of phenol-alcohols per Chapter 29 scope. Key additive in consumer electronics housings.
