Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the compound contains a nitrogen function other than the imine, such as a nitroso group
Other nitrogen-function compounds are classified in heading 29.29, but the imine function is primary here.
If imported as a synthetic organic colouring matter
Dyes and colouring matter are excluded from Chapter 29 by note 2(g) and classified in heading 32.04.

Import Tips & Compliance
• Provide the exact chemical name and CAS number to CBSA to confirm classification under 2925.29.00, as the dimethylamino group does not shift it to heading 29.29
• Ensure the product is not put up in measured doses or for retail sale, which would trigger section note 2
• Keep documentation on the synthesis to prove it is a single chemically defined compound
