Import Tips
• Although Chapter 25 generally excludes heat-treated products, heading 25.13 explicitly includes natural abrasives 'whether or not heat-treated,' so this powder qualifies
• Ensure the corundum is natural, not synthetic, as synthetic corundum falls under Chapter 28
• Provide documentation of the natural origin and heat-treatment process to CBSA
