Import Tips & Compliance
• Verify scrap purity and tungsten content via assay certificates to confirm classification as tungsten waste under Chapter 81
• Provide documentation proving origin as scrap (e.g
• generator declarations) to avoid misclassification as unwrought tungsten
• Comply with EPA recycling regulations for hazardous waste if contaminated; declare any attachments separately
