Import Tips
• Provide assay reports showing leucite content >70% to prevent reclassification as general mineral mixtures
• Check CITES permits if sourced from protected volcanic regions; improper docs cause 100% duty penalties
• Declare exact particle size distribution; fines risk heading 2517 classification as 'pebbles/grit'
