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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for halogenated phenol-alcohols without bisphenol structure
Simpler halogenated phenols fall under the 2903.69 basket, while TBBA's specific structure dictates 2908 classification.
If imported as goods specified in note 1(c) like certain pesticide intermediates
Specific Chapter 29 exclusions apply, but TBBA as flame retardant stays in its primary organic compound heading.

Import Tips & Compliance
• Label with exact CAS 79-94-7 and chemical name per 49 CFR hazardous materials regulations for DOT compliance
• Screen for Proposition 65 warnings if California-bound, as brominated compounds may trigger chemical listing
• Document stabilizer content <1% to stay within Chapter 29 note (f) for added preservatives

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.
