Import Tips
• Verify purity certificate (typically >99% Re) to confirm classification as chemically defined ammonium perrhenate
• Include Material Safety Data Sheet (MSDS) due to toxicity; ensure proper hazmat labeling for air/sea shipment
• Avoid misclassification as rhenium metal (HTS 2805.30); provide assay reports showing ammonium salt form
