Import Tips
• Verify the exact chemical composition; if the product is predominantly dinitro, it may still be classified under 2921.44.00 if it is a derivative of diphenylamine
• Provide a certificate of analysis to CBSA
• Note that explosive-related uses may require additional permits from Canadian authorities
