Import Tips
• Specify particle size and purity in invoice to distinguish from wrought powders; use sieve analysis certificates
• Ship under inert gas to prevent auto-ignition; include UN hazard class 4.2 if applicable
• Avoid classifying as 'articles' if loose powder—customs may challenge based on packaging
