Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hafnium bars or rods
Wrought forms like bars are specifically under 8112.12; ingots considered 'other' if not standard shapes.
If ferro-hafnium alloy
Ferro-alloys containing hafnium are classified under Chapter 72 iron/steel ferrosilicon types.
If processed into semiconductor wafers
Finished electrical devices/articles from hafnium shift to Chapter 85 machinery/electrical.

Import Tips & Compliance
• 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
