Import Tips
• Provide metallurgical assay reports proving hafnium ≥99% to distinguish from Chapter 81 alloys
• Label as 'other hafnium articles'; bulk shipments may require hazardous material declarations if pyrophoric
• Check NRC licensing for nuclear-grade hafnium imports, even if not waste/scrap
