Import Tips
• Ensure the bricks are fired after shaping and not merely dried, as Chapter 69 excludes unfired articles
• If the vermiculite content is significant, verify the product is not classified as an exfoliated vermiculite under heading 6806
• Provide a declaration of the firing process to the CBSA
