Import Tips & Compliance
• Verify the blocks are not polished or treated with sealants, as this would change the classification to worked stone
• Document the natural vein patterns and sawing process to support the tariff classification
• If the blocks are destined for luxury surfaces, ensure they meet any Canadian building code requirements for imported stone
