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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in the form of salts rather than free phenol
Halogenated phenol salts are specifically provided for in 2908.19.10, separate from the pure TBBA compound.
If blended with anti-dusting agents exceeding Chapter 29 note (g) limits
Additives rendering it suitable for specific non-general use shift classification from pure compounds to chemical preparations.
If dissolved in hydrocarbon solvents beyond transport-safety concentrations
Chapter 29 note (e) excludes solutions where solvent makes it suitable for specific uses, potentially moving to petroleum oils.

Import Tips & Compliance
• Include certificate of analysis confirming ≥99% TBBA content to prevent disputes over impurity levels affecting Chapter 29 classification
• Comply with TSCA Premanufacture Notice if aggregate imports exceed reporting thresholds; maintain records for 5 years
• Avoid packaging that suggests retail sale, which could trigger reclassification under preparations in heading 3824

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.
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.
