Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 99%+ aluminum purity
Pure aluminum not alloyed falls under 7601.10 as non-alloyed unwrought aluminum, per subheading note (a) purity table.
If processed into wire form under 6mm cross-section
Wire products of aluminum alloys, even from unwrought material, are classified as other articles in 7616.91 per specific chapter note.
If shaped into powders of aluminum alloys
Aluminum alloy powders are classified under 7603.10, separate from unwrought ingot or bar forms.
