Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If diameter 1.0 mm to 1.5 mm
Slightly thicker high-carbon round coated wire uses the adjacent diameter-based subheading.
If formed into spring assemblies
Assembled or further fabricated into structures like panels classifies as metallic structures.
If tool steel per note (e)
Specific high-carbon alloy combinations meeting tool steel definition go to alloy tool steel wire.
