Import Tips

Report assay quantity of silver content without deductions as per statistical notes; obtain certified lab analysis

Ensure documentation proves industrial use for metal extraction to avoid reclassification under waste codes

Comply with EPA regulations on arsenic-bearing materials; common pitfall is improper hazardous waste labeling
