Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If circular cross-section under 800mm
Bars/rods hot-rolled in irregularly wound coils classify under 7213.
If heat-resisting steel per Note (g)
Low carbon (<0.3%), 4-10.5% Cr steels for heat resistance have separate provisions.
If artificially oxidized or phosphatized
Chemical surface treatments defined as 'further worked' in Chapter note.

Import Tips & Compliance
• Hot work steels need precise Cr/Mo cert for Note (e)(iv) - common CBP verification point
• Width/thickness ratio determines flat bar vs plate classification boundary
• Not for razor blade use - that requires specific 7222.30 cert per Note (d)
