HBCD α-Isomer Flame Retardant from Canada

Alpha-isomer specific hexabromocyclododecane (HBCD), a stereoisomer used in eco-friendlier flame retardant formulations for electronics housing. Classified under 2903.89.70.10 as 'other HBCDs' per Chapter 29 note (b) for mixtures of isomers, though supplied as separated isomer of the brominated cyclododecane. Its halogenated cyclic hydrocarbon structure defines its placement.

Import Tips

• Provide stereoisomer composition analysis (NMR/GC) to distinguish from generic HBCD and confirm chemical definition

• Check Stockholm Convention restrictions; many countries ban commercial HBCD mixtures except specific isomers

• Label with exact isomer ratio to prevent reclassification as unspecified HBCD under same code
