Import Tips & Compliance
• Verify the blocks are not polished or surface-treated, as this would shift classification to worked stone under Chapter 68
• Keep invoices and packing lists showing the blocks are in raw, sawn form
• If the blocks are part of a countertop kit with other materials, consider whether they are classified as a set
