Import Tips
• Provide XRF chemical analysis confirming leucite composition (>50% KAlSi2O6) to prevent confusion with nepheline
• Declare radioactivity levels if from volcanic sources; comply with USGS import guidelines for strategic minerals
• Avoid packaging that suggests processing; use 'crude ore' labeling to maintain 2529 classification
