Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not cold-rolled, only hot-rolled
Hot-rolled alloy steel strips fall under 7225, while cold-rolled moves to 7226
If width 300-600 mm
Same cold-rolled alloy steel but wider strips classified in 7226.99 subheading
If meets tool steel definition per Chapter Note 72(e)
Tool steels have specific alloy compositions that shift classification within 7226
