Import Tips & Compliance
• Confirm the resin is uncompounded and in primary form (e.g
• liquid or flakes) to meet the tariff item requirements
• Provide a certificate of analysis showing the allyl monomer content is at least 95% by weight
• Be prepared to explain the end-use (e.g
• optical lenses) if requested by CBSA
