Import Tips
• Verify that the phosphate group does not confer a separate organo-inorganic classification under heading 29.31; the ether-phenol core governs
• Provide the molecular structure documentation to CBSA to support the classification
• Check if the product is subject to chemical precursor monitoring regulations
