Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from unsaturated hydrocarbons
Derivatives of unsaturated acyclic hydrocarbons like butene dichlorides classify under 2904 rather than saturated derivatives.
If in pesticide intermediate formulations
When prepared specifically for pesticide manufacture, classification moves to Chapter 38 goods for insecticide production.
If 1,2-dichloropropane content predominates in mixture
Mixtures where named compounds predominate may use specific provisions over general dichlorobutanes.
