Import Tips
• Ensure the product is calcined or further heat-treated beyond impurity removal, as untreated natural phosphates fall under heading 2510
• Keep documentation of the heat-treatment process for CBSA verification
• Verify the product is not put up in forms or packages described in heading 31.05, which would change classification
