Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hot-rolled precursor form
Before cold-rolling, classifies as hot-rolled alloy steel flat-rolled products in 7225.
If clad or coated with metal
Metal cladding constitutes 'further worked' per Chapter notes, moving to 7226.99.
If plated/based on non-alloy steel
Non-alloy base with plating shifts to Chapter 72 plated products, not alloy flat-rolled.

Import Tips & Compliance
• Certify no 'further worked' treatments like phosphatizing per US notes; clean mill finish only
• Batch test for alloy content—spot checks prevent misclassification to stainless (Ch 72) or carbon steel
• Document cold-rolling reduction ratio if audited; distinguishes from hot-rolled under 7225
