Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If narrower than 600 mm
Flat-rolled alloy steel under 600 mm width shifts to heading 7212 or 7226 series.
If heat-resisting per note (g)
Heat-resisting alloy steels have dedicated subheading 7225.40 before other surface treatments.
If plated with other metal like nickel
Plating with metals other than zinc uses 7225.91; zinc-specific is 7225.92.
