Import Tips
• Provide evidence of the stone's apparent specific gravity of 2.5 or more, as this is critical for classification under heading 2515
• Ensure the blocks are only roughly trimmed or cut into rectangular shapes; further processing may lead to classification elsewhere
• Be prepared to describe the stone's calcareous nature to CBSA officers if questioned
