Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If produced from stainless angle/bar stock
Different alloy steel forms classify under bars/rods rather than wire.
If when containing substantial flux core material
Cored wire with filler materials classified as electrodes of base metal.
If copper content dominates as stranded copper
Primarily copper wire products fall under Chapter 74 copper articles.
