Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not in coils but straight lengths
Hot-rolled bars/rods not in coils go to 7228 for other alloy steel forms.
If forged rather than hot-rolled
Forged bars have separate heading 7214, different from continuously cast hot-rolled coils.
