Import Tips
• Ensure the product is anhydrous and free of added substances that would render it suitable for a specific use, as Chapter 28 Note 1 restricts classification
• The CBSA may require a certificate of analysis to confirm the purity and chemical identity
• Verify that the product is not put up in measured doses or for retail sale, which would change the classification
