Import Tips
• Ensure the resin is in primary form (prills, granules, or powder) and not further worked, as tariff item 3911.20.00 applies only to primary forms
• Provide a detailed product specification sheet to the CBSA confirming the chemical composition is poly(1,3-phenylene methylphosphonate) with at least 95% polymer content
• Verify whether the resin qualifies for duty-free treatment under preferential trade agreements by checking the certificate of origin
