Import Tips
• Quarry-run often volume-weighed; convert accurately to metric tons using certified pumice density (0.4-0.8 g/cm³)
• Avoid bagging before export to prevent 'retail set' reclassification; ship in bulk supersacks
• Traceability docs from mine to port prevent fraud claims on natural origin
