Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further worked (polished, coated, or clad)
Further worked per Chapter 72 note moves to 7225.40; high-speed steel but surface treated beyond hot-rolling.
If not qualifying as high-speed or tool steel
Regular alloy steel without specific high-speed composition falls under other alloy steel categories.
If width under 600 mm
Narrower flat-rolled products shift to Chapter 72 heading 7226.

Import Tips & Compliance
• Provide mill test certificate confirming high-speed steel composition per US Note (e) with >1.2% carbon and specific alloy elements
• Verify exact thickness <4.75mm and width ≥600mm; coils must be hot-rolled only, no further working like polishing
