Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily as a heterocyclic compound rather than organo-inorganic
Endosulfan's structure includes heterocyclic elements; if emphasis is on ring structure over inorganic acid ester, it may shift to Chapter 29 heterocyclic provisions.
If considered a halogenated derivative of alcohols rather than acid ester
Alternative chemical interpretation focusing on alcohol-halogen functionality could place it under halogenated hydrocarbons of heading 2903.
