Import Tips
• > Ensure the pyroxylin is not plasticized or mixed with other polymers, as this could affect classification under subheading note 1
• Provide a certificate of analysis showing the nitrogen content (typically 10.5–12.3%) to the CBSA
• If the resin is used in aerospace applications, verify any end-use or import permit requirements with relevant Canadian authorities
