Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in coil form with max dimension ≤6mm
Thin wire-like hollow profiles in coils classify under 7607 per subheading note.
If made into finished table/base/kitchen articles
End product use (e.g., furniture legs) shifts from profiles to cast/formed articles.
If unalloyed aluminum version
Purity threshold determines alloy vs non-alloy heading.
