Import Tips
• 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
