Import Tips
• Ensure the tufa blocks are only sawn or cut, with no added surface treatments, to maintain classification under this item
• Document the volcanic origin and density of the tufa for CBSA verification
• If blocks are used in load-bearing structures, confirm they meet Canadian building codes, as CBSA may require additional documentation
