Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the salicylidene group is part of a nitrogen-containing heterocyclic ring
Nitrogen heterocycles are classified under heading 29.33, which is more specific than acyclic imines.
If the compound is a carboxylic acid derivative rather than an imine
Carboxylic acids with oxygen functions are classified in heading 29.18, but the imine function governs here.

Import Tips & Compliance
• Confirm the product is not a salt or a metal complex, as those may be classified differently under Chapter 29 notes
• Provide the photochromic properties and end use to CBSA to support classification as an imine derivative
• Ensure the product is not put up in forms for retail sale, which could trigger section note 2
