Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when sold as rubber vulcanization additive mixture
Prepared rubber accelerators with compounding agents fall under Chapter 38, not pure organic compounds.
If classified as other organo-sulfur rather than specific dithiocarbamate
Broader organo-sulfur heading applies if dithiocarbamate structure not principal characteristic.
