Import Tips
• Provide slab dimensions and photos proving rectangular block/slab form without further shaping
• Avoid common pitfall of classifying as flagstones if dimensions suggest pavement use—stick to building/monumental intent
• Label clearly as 'roughly trimmed' to prevent reclassification as worked stone under Chapter 68
