Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not the specific CAS-listed compound
Other toluidine derivatives fall under broader 2921.43.50; specificity of CAS 88-51-7 dictates the .9020 subheading.
If for industrial bulk without amine identification
Sodium sulfates of organic compounds may shift to inorganic salts if amine function not principal characteristic.
If diluted in solvent for transport
Solutions for safety/transport per chapter note (e) could classify as chemical preparations if solvent alters general use.
