Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width under 600 mm
Alloy steel flat products <600 mm wide, even high-speed steel, classify under 7226.
If clad or coated with other metals
Metal coating qualifies as 'further worked' per Chapter note, moving to 7225.40.30.
If thickness under 4.75 mm
Thinner hot-rolled alloy steel plates ≥600mm wide use 7208.51.

Import Tips & Compliance
• Cobalt content documentation essential - distinguishes from standard M2/M35 for proper high-speed steel verification
• Check for 'universal mill plate' characteristics (note b) which might affect classification if patterned
• Ensure no chemical surface treatments (phosphating, etc.) as these constitute 'further worked'
