Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chipper knife steel per US Note 72(f)
Exact elemental composition match (C 0.48-0.55%, Cr 7.25-8.75%, etc.) triggers specialized classification.
If in coils instead of plate form
Coiled hot-rolled products separate from not-in-coils plates regardless of alloy/thickness.
If of silicon-electrical steel composition
Grain-oriented silicon steel for electrical use has distinct heading.

Import Tips & Compliance
• US Note prohibits duty reduction for rust; classify based on actual condition at entry regardless of surface appearance
• Differentiate from razor blade steel (US Note 72(d)); this lacks stainless/narrow specs
• For sets with fittings, may classify as 7326 if assembled for specific function
