Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered organo-sulfur metal salt primarily
Chapter 29 note prioritizes organo-sulfur classification (2930) over heterocyclic (2934) when applicable.
If imported primarily as metal corrosion inhibitor
Certain metal salts used solely as inhibitors may fall under inorganic sulfides of Chapter 28.

Import Tips & Compliance
• Classify per Chapter 29 note (C)(1) with the parent organic compound (2-mercaptobenzothiazole)
• Include metal content analysis to distinguish from other organo-metallic compounds
• Label as hazardous material if dust inhalation risk exists during handling
