Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If scrap is melted and cast into ingots before import
Remelted scrap becomes unwrought ingots, still under 8112.31 but distinguished from raw scrap.
If alloyed with significant iron content (>99% other metals)
Ferrohafnium alloys with iron as primary base metal shift to Chapter 72 iron/steel alloys.
If containing radioactive residues exceeding regulatory limits
Radioactively contaminated metal scrap is classified under 2620 as ash and residues.

Import Tips & Compliance
• Include radiation survey reports confirming scrap is below exempt quantities to avoid NRC licensing
• Document origin and chain of custody to prevent classification issues with contaminated scrap
• Sort and segregate by alloy content to maintain pure hafnium scrap status
