• Report assay zinc content precisely without deductions per statistical notes to avoid reclassification
• Provide smelter origin certificates proving industrial use for metal extraction to comply with Chapter 2620
• Test for arsenic levels; exceeding thresholds may shift to waste headings like 2621
