Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If o-phenylenediamine structural analog
Specific isomers like o-phenylenediamine have priority subheadings before 'other' polyamines.
If containing carboxamide function
Oxygen/nitrogen function compounds supersede pure amine classification per chapter notes.
If pre-polymerized into polyamide resin
Polymerized amino compounds become Chapter 39 plastics, not Chapter 29 monomers.

Import Tips & Compliance
• Label with exact IUPAC name and CAS 823-40-5 to prevent confusion with p- or o- isomers
• Comply with EPA TSCA inventory requirements; pre-notify for new uses
• Avoid declaring as 'diaminotoluene' generically; specify meta isomer per HTS description
