Import Tips
• Submit detailed chemical composition report highlighting zinc majority and silver assay for accurate statistical reporting
• Confirm industrial extraction intent via end-user certificates to prevent misclassification as waste
• Watch for particle size documentation if coarse; avoid blending with iron residues to maintain 2620 eligibility
