Import Tips
• Ensure the coating is not a separate chemically defined compound, which would be excluded from Chapter 38
• Verify that the product is not classifiable under heading 85.46 or 85.47 as an electrical insulator
• Provide a safety data sheet to CBSA, as PFOS substances are subject to strict Canadian regulations
