Import Tips
• Report silver content via assay certificate without deductions per statistical notes; include lab analysis for customs valuation
• Verify absence of municipal waste incineration origin to avoid reclassification under 2621; provide smelter process documentation
• Ensure hazardous material declarations for arsenic content; common pitfall is underreporting metal quantities leading to penalties
