Import Tips
• 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
