Import Tips
• Laser-inscribe unique KP numbers on larger parcels (>1 carat) for traceability during customs inspection
• Avoid common pitfall of declaring total weight without distinguishing industrial vs potential gem parcels
• Consult CBI for advance ruling on specific miner diamond grading to lock in classification
