Import Tips
• Provide equipment origin documentation to prove rhenium filament composition and avoid 7419 classification
• Segregate from tungsten filaments (8101.99) during import inspection to prevent commingling errors
• Include smelter recovery yield estimates in commercial invoice for customs valuation
