Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the turnings are primarily beryllium rather than hafnium
Beryllium waste/scrap falls under separate subheading 8112.19.00 within the same chapter.
If scrap originates from electrical assemblies containing hafnium
Electrical waste/scrap with precious/rare metals is classified under Chapter 85.
If chemically processed into granules during recovery
Granulated metal waste from chemical recovery processes goes to Chapter 26.
