Import Tips
• Document the stabilizer and its purpose (e.g
• anti-caking) to demonstrate compliance with Chapter 29 Note 1(f)
• Ensure the stabilizer does not make the product suitable for a specific use; otherwise, reclassification may apply
• Provide safety data sheets (SDS) to CBSA for hazardous goods clearance
