Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If isomeric mixtures containing TRIS
Chapter note (b) classifies isomer mixtures separately from pure named compounds.
If imported as brominated propanol intermediate
If not esterified or considered alcohol derivative, falls under halogenated acyclic alcohols.
If solutions in organic solvents for safety transport
Chapter note (e) excludes solvent solutions unless solely for transport; otherwise chemical preparations.

Import Tips & Compliance
• Submit GC-MS or NMR analysis confirming molecular structure matches named compound for Customs verification
• Declare exact bromine content (typically 68-70%) as it validates chemical identity under this specific HTS
• Package in UN-approved chemical drums; improper packaging leads to hazardous material surcharges
