Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-aromatic (aliphatic) analog
Heading 2930 distinguishes aromatic (2930.90.29) from non-aromatic organo-sulfur compounds (2930.90.90).
If considered cyclic hydrocarbon derivative
Some sulfur-containing cyclic hydrocarbons may fall under Chapter 29 hydrocarbons if sulfur not principal function.
If for fuel additive formulations
Antioxidant compositions containing these compounds for fuel use shift to heading 3811.
