Dibromoneopentylglycol (FR-513)
Dibromoneopentylglycol, chemically known as 2,2-bis(bromomethyl)-1,3-propanediol, is a halogenated acyclic alcohol used primarily as a reactive flame retardant in polyurethane foams and resins. It falls under HTS 2905.59.30.00 as a specific brominated derivative of neopentylglycol, an acyclic diol, meeting Chapter 29's criteria for chemically defined organic compounds with halogen directly linked to carbon.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically named as dibromoneopentylglycol
Other halogenated acyclic alcohol derivatives fall into the residual 'Other' subheading when not explicitly listed like dibromoneopentylglycol.
If imported as a formulated flame retardant mixture
Chemical preparations containing dibromoneopentylglycol with additives exceed Chapter 29's scope for pure compounds and classify as mixtures.
If considered a halogenated polyol intermediate rather than alcohol derivative
Alternative classification possible under halogenated acyclic alcohols if principal function interpreted as polyhydric rather than diol-specific.
