Import Tips
• Submit flotation process details and zinc assay reports to verify classification within silver ore hierarchy
• Label shipments clearly as 'zinc content' for statistical purposes; non-compliance leads to reclassification
• Check for polymetallic ore rules; excessive lead may trigger alternative headings
