Import Tips
• Ensure the residue is not from iron or steel manufacturing, as those fall under a different heading
• Provide a certificate of analysis showing zinc content to support classification
• Check if the arsenic content triggers any hazardous waste import permit requirements under Canadian environmental regulations
