Import Tips
• Report silver content as assay quantity without deductions per statistical notes to avoid misclassification
• Verify residue originates from non-iron/steel processes and is used for metal extraction, not incineration waste
• Obtain lab assays for copper/silver composition to support 'mainly copper' claim and prevent reclassification
