Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel cold-rolled but not tool steel quality
Tool steel requires specific note (e) compositions; general alloy steel goes to 'other' provisions.
If hot-rolled rather than cold-rolled
Processing state determines cold-rolled (7225.50) vs hot-rolled (7225.30) subheadings.
If imported as finished ball bearing races, not raw steel
Finished bearing components classify in Chapter 84 as parts of ball/roller bearings, not raw material.

Import Tips & Compliance
• Submit entry with certified analysis report proving compliance with all 9 element specifications in US Note (h)
• Measure and declare exact width/coil dimensions; uncoiling for measurement may be required by CBP
• Segregate from universal mill plate (note b) which has different width/thickness specs
