Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other electrical alloy steel
Other specialized electrical alloy steels >600mm not silicon-grain-oriented go to 7225.50.
If stainless/high alloy variant
If alloy composition shifts to stainless steel specs per Chapter 72 notes, classifies under 7220.
If insulated for electrical use
Coated with insulation material becomes insulated wire/cable under Chapter 85.
