Import Tips
• Confirm the stabilizer (BHT) is added solely for preservation and does not make the product suitable for a specific use
• Provide the stabilizer concentration and purpose in the documentation
• If the stabilizer content is unusually high, the CBSA may question whether it remains a separate chemically defined compound
