Tetrabromophenol A
Tetrabromophenol A (2,4,6-tribromophenol with additional bromination) is a brominated phenol with only halogen substituents. HTS 2908.19.60.00 applies to this 'other' derivative used in flame retardant synthesis. Bromine provides higher flame suppression than chlorine analogs.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ether derivatives formed during synthesis
Halogenated phenol ethers classify in 2909; chapter notes prioritize last numerical heading.
If technical mixtures with solvents/stabilizers
Preparations with added solvents beyond transport needs fall to Chapter 38 per exclusion notes.

Import Tips & Compliance
• Brominated compounds require additional REACH-like documentation for persistence/bioaccumulation under TSCA
• Verify 'only halogen' status; bromination catalysts may leave metallic impurities requiring 2931 classification
• Technical grade imports common; ensure bulk packaging doesn't qualify as 'retail packing' under Note 2(g)
