Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chipper knife steel per note (f)
Chipper knife steel tool steel has different Cr/Mo/V composition, classifying under 7228.60.60
If bars of circular cross-section ≤80mm containing indentations
Cold-formed bars with deformations may fall under 7213.91 per concrete reinforcing note (c)
If supplied as angles/shapes/sections
Alloy steel angles, shapes, sections classify in 7225, differentiated from straight bars/rods

Import Tips & Compliance
• Provide European DIN/EN certification documents; ensure no cladding/coatings that constitute 'further worked' per Chapter note; confirm rod diameter keeps it as 'other bars' vs sheet/plate
