Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If reaction accelerator with >20% other catalysts
Catalyst mixtures (3815) if no longer primarily the named compound; Chapter 29 requires principal characteristic as separate compound.
If aniline derivative form predominates
Aromatic monoamines (2921.42) if structure shifts; numerical order places specific 2921.19 last for this compound.
If for diagnostic lab reagents containing this compound
Diagnostic reagents (3822) exclude Chapter 29 pure compounds; specific use formulation changes classification.

Import Tips & Compliance
• Document stabilizer as necessary for transport per note (f) to prevent reclassification
• Use UN-approved chemical packaging for Hazard Class 6.1 poisons
• Conduct stability testing for CBP verification
