Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with plasticizers or solvents for direct application
Mixtures of chemical preparations not purely chemically defined fall under Chapter 38 prepared chemical headings.
If containing fewer than six bromine atoms on biphenyl structure
Other halogenated aromatic derivatives without the specific hexabromobiphenyl structure classify under the residual 2903.99 provision.
If Products of Chapter 38 for pest control or disinfection take precedence over pure Chapter 29 compounds.
