Import Tips
• Verify stone composition via geological testing to confirm it's limestone and not marble (Chapter 25 exclusion for certain processed stones)
• Include certificates of origin and quarry documentation to avoid misclassification as setts or curbstones under 6801
• Check for rough trimming only; further processing like polishing may shift to Chapter 68 headings
