Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If benzimidazole ring system specifically identified
Benzimidazole compounds have dedicated 2933 subheading taking precedence.
If imported as prepared rubber vulcanization accelerator
Prepared rubber chemicals classified in 3812 over pure compounds.
If sulfur-carbon linkage dominates over amide function
Organo-sulfur compounds in 2930 if not excluded by note 5 sulfonation rules.
