Import Tips
• Confirm the specific gravity is 2.5 or more with a lab test or supplier certificate to support classification under heading 2515
• Ensure the blocks are only roughly trimmed or cut into rectangular shapes; additional processing may change the tariff classification
• Keep records of the stone's origin and composition in case CBSA requests verification
