Import Tips
• Provide a certificate of analysis confirming purity and absence of impurities that might alter classification
• Ensure the product is not put up in measured doses or for retail sale, as that could trigger Section VI Note 2 and move it to another heading
• Consult the CBSA for advance rulings if the powder is blended with stabilizers, as stabilizers may affect classification under Chapter 28
