Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further worked than cold-rolled (e.g., polished)
Next heading 7226 covers alloy steel further worked beyond cold-rolling.
If of heat-resisting steel per note (g)
Different alloy note definitions (low C, high Cr) shift tool steel sub-classification.
If non-alloy plated/coated steel
Material composition (alloy vs non-alloy) determines Chapter 72 heading structure.

Import Tips & Compliance
• ASTM A485/A295 test reports essential to prove tool steel/ball-bearing qualification
• Prevent misclassification as razor blade steel (note d) by confirming width >23mm and Cr content
• Maintain coil integrity during transit; damage claims denied per Chapter note on rust
