Import Tips
• Include Certificates of Authenticity from accredited labs (e.g
• HRD Antwerp) specifying synthetic reconstructed nature per Chapter 71 notes
• Avoid common error of declaring as 'rough' if faceted; precise cutting descriptions prevent reclassification
• For bulk imports, segregate by quality grades to match statistical suffixes accurately
