Import Tips
• Ensure the quicklime is shipped in bulk with proper moisture barriers, as hydration reduces its effectiveness in cyanidation
• Declare the end-use as mining to CBSA, but note that the classification remains quicklime regardless of use
• Check if the Canadian Environmental Protection Act applies if the quicklime is handled in large quantities
