Import Tips
• Confirm the pellets are in primary form and not extruded into sheets or profiles before importation, as tariff item 3911.20.00 applies only to primary forms
• Provide the CBSA with the exact chemical name and CAS number for poly(1,3-phenylene methylphosphonate) to avoid misclassification
• Check if the pellets are subject to Canadian import restrictions on phosphonate compounds under chemical management plans
