2908.19.25.00 - Tetrabromobisphenol A 🖩

This classification covers Tetrabromobisphenol A (TBBPA), a brominated flame retardant widely used in electronic components, circuit boards, and plastics. TBBPA is characterized by the presence of four bromine atoms attached to a bisphenol A molecule, significantly enhancing its flame-retardant properties. Its specific chemical structure and functionality are the primary drivers for its inclusion within this distinct HTS subheading.

While other subheadings at this level address various halogenated phenol derivatives, this entry specifically isolates TBBPA. For instance, it is differentiated from 2,2-Bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane (2908.19.05.00) by the absence of fluorine atoms and the presence of bromine instead. Similarly, it is distinct from compounds like 6-chloro-m-cresol and chlorothymol (2908.19.10.00) due to its specific structure and a higher degree of halogenation. The other listed siblings deal with trifluorinated toluenes, pentachlorophenol salts, and 2,4,5-trichlorophenol and its salts, none of which share the defining chemical architecture of Tetrabromobisphenol A.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus remains on the precise identification of Tetrabromobisphenol A based on its unique chemical composition and application. Importers and exporters should ensure that goods classified under 2908.19.25.00 are indeed Tetrabromobisphenol A, distinguishing it from any other brominated or halogenated derivatives of phenols or phenol-alcohols that might fall under broader or more general categories.
