Import Tips & Compliance
• > Verify the monomer purity (≥95%) with a certificate of analysis to support classification
• Ensure the flakes are not further worked (e.g
• cut into shapes) to remain in primary form
• Provide a detailed product description on the commercial invoice to expedite CBSA clearance
