Import Tips & Compliance
• Document that the BHT stabilizer is solely for preservation and does not make the product suitable for a specific use, as required by Chapter Note 1(f)
• Provide the exact concentration of the stabilizer to the CBSA
• The stabilizer does not change the classification under 2909.41.00
