Import Tips
• Include petrographic analysis reports to distinguish from excluded earth colors or other minerals per chapter notes
• Ensure slabs are rectangular and not further shaped; any drilling or edging reclassifies to Chapter 68
• Check for radioactivity in stone imports; some building stones require additional customs declarations
