Import Tips
• Verify sieve test certification showing 90%+ passes 0.5mm mesh to meet 'powder form' per subheading note
• Provide lab analysis confirming natural origin (not synthetic) to avoid reclassification under 7105.90
• Declare exact particle size distribution; common pitfall is mislabeling as abrasive under Chapter 68
