Import Tips
• Document the type and concentration of the antioxidant used, as the CBSA may verify it is solely for preservation and not for making the product suitable for a specific use
• Ensure the packaging is compliant with Canadian transportation of dangerous goods regulations, as THF is flammable
• Provide a letter of certification from the manufacturer regarding the peroxide-free status to avoid delays
