Import Tips
• Confirm the degree of substitution (DS) of the acetate groups, as this may affect the physical form and classification
• Keep records of the manufacturing process to demonstrate esterification, in case the CBSA requests verification
• If the product is used in food-contact applications, verify compliance with Canadian Food Inspection Agency (CFIA) requirements, though the tariff classification remains under Chapter 35
