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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a flame retardant mixture or masterbatch with polymers
Mixtures of organic chemicals not chemically defined fall under heading 3824 rather than pure compounds in Chapter 29.
If chemically modified with additional substituents beyond halogens
Other halogenated phenol derivatives with mixed functional groups are classified in the broader 2908.19.90 basket, not the specific TBBA subheading.
If supplied as a stabilized solution for transport safety
Per Chapter 29 note (e), solutions in solvents for safety/transport may remain classified here, but highly diluted forms could shift to mixtures in 2933.

Import Tips & Compliance
• Verify purity and ensure product meets chemical definition as TBBA without additional functional groups to avoid reclassification under other Chapter 29 headings
• Provide Safety Data Sheets (SDS) and TSCA certification, as TBBA is regulated under EPA for chemical import notifications
• Watch for REACH compliance documentation if sourced from EU, and avoid common pitfalls like mislabeling as a mixture which shifts to heading 3824
