Import Tips
• Provide detailed chemical analysis and particle size distribution certificates to confirm non-lamellar structure and purity
• Declare average particle size (typically <45 microns for powders) to avoid reclassification as flakes under 7406.20
• Ensure MSDS includes handling precautions for fine metal powders to prevent explosion risks during customs inspection
