Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in coil form or hot-rolled
Coiled or hot-rolled products shift to 7224 subheadings, distinct from forged bars.
If further worked like ground
Any grinding or polishing post-forging moves it to 'other bars and rods, not further worked than cold-formed or finished' under 7228.50.
If low-alloy or carbon steel
Bars with insufficient alloy elements default to Chapter 72 carbon steel headings like 7214.

Import Tips & Compliance
• Provide chemical analysis certificates proving >1.5% Ni and Cr-Mo content for alloy verification; inspect for any scale removal that could be deemed 'further worked'; use proper packing to prevent rust, as no duty allowance for pre-entry discoloration per Chapter notes
