Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If 600mm+ width and universal mill plate specs
Universal mill plate definition in Note (b) for 150-1250mm width, 4mm+ thick, not coiled, classifies under 7225 if wider than 600mm.
If generic alloy steel not matching chipper knife composition
Fails specific Note (f) elemental requirements; becomes other non-tool alloy steel hot-rolled under 600mm in 7226.19.
If imported as finished concrete reinforcing bars
End product use as deformed reinforcing bars per Note (c) shifts from raw steel to tubes/pipes/articles classification.

Import Tips & Compliance
• Include detailed heat analysis report showing compliance with all seven chipper knife steel elements (C, Mn, Si, Cr, Mo, W, V)
• Photograph products pre-shipment to document hot-rolled surface condition against potential CBP further-worked challenges
• Monitor for minimum yield strength if marketed as high-strength, which has separate note (a) definitions affecting other codes
