Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tool steel composition
Cold-rolled tool steels meeting Chapter 72 note (e) elemental specs classify in tool steel subheadings.
If plated or coated post-rolling
Cold-rolled sheets with metal or plastic coatings are further worked, moving to Chapter 72 coated headings.
If of heat-resisting steel type
Low-carbon Cr alloy steels meeting heat-resisting definition in note (g) have dedicated subheading.

Import Tips & Compliance
• Certify nickel content >63% per Monel specs; generic 'nickel alloy' declarations often rejected
• Confirm no artificial oxidation or phosphatizing occurred, as these constitute 'further worked' per notes
