HBCD α-Isomer Flame Retardant
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied with nitrogen-containing stabilizers
Esters or salts with nitrogen functions classified later in Chapter 29 per classification note.
If for industrial plastic additive preparations
Chemical preparations not meeting Chapter 29 purity criteria shift to Chapter 38.
If containing fluorinated substituents
Different halogenated derivatives have specific subheadings earlier in numerical order.

Import Tips & Compliance
• 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
