Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diluted with solvents for transport exceeding chapter 29 note (e) limits
Preparations with solvents rendering them suitable for specific non-general use classify under 3808 pesticides, not pure Chapter 29 compounds.
If alcohol derivative classification predominates over sulfur function
Esters of alcohols with acid functions may classify under later oxygen-function headings per chapter note on ester classification rules.
If imported as aromatic organo-sulfur compound without pesticide use
Non-pesticide aromatic organo-sulfur compounds go to the 2930.90.91 basket for other specified compounds.
