Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the compound is modified to contain a nitroso group instead of a nitro group
Nitroso compounds are classified under heading 29.29 for nitrogen-function compounds, though nitro groups alone do not trigger this.
If the benzene rings are replaced by a nitrogen-containing heterocyclic structure
Heterocyclic imines fall under heading 29.33, which is more specific than acyclic imines.

Import Tips & Compliance
• Provide the chemical structure and CAS number to CBSA to confirm classification as an imine derivative under 2925.29.00
• Note that nitro groups are not considered nitrogen functions for heading 29.29, so this product stays in 29.25
• Declare the end use (e.g
• explosive detection) to facilitate clearance, but ensure it is not put up as a reagent for retail sale
