Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If universal mill plate dimensions
Width 150-1250mm, thickness ≥4mm per note (b) reclassifies.
If part of complete chipper assembly
Machinery parts assembled into sets classify under Chapter 84/85.
If generic other alloy steel
Failing any note (f) element moves to nonspecific alloy steel.

Import Tips & Compliance
• Specify 'for chipper knife mfr' on commercial invoice to support specific subheading
• Vanadium tolerance critical (0.2-0.55%); excess may shift to other tool steel
• Avoid commingling with universal mill plate; dimensional specs must match bars
