Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heat-resisting tool steel composition
Heat-resisting steel (<0.3% C, 4-10.5% Cr) per U.S. Note (g) classifies separately from ball-bearing steel.
If thickness 4.75 mm or more
Thickness threshold separates subheadings within 7225.40; ≥4.75 mm moves to thicker tool steel category.
If not tool steel (lacking specified alloy combos)
Fails tool steel definition in U.S. Note (e), classifying as general hot-rolled alloy steel sheets.

Import Tips & Compliance
• Submit detailed chemical analysis certificates proving SUJ2 matches ball-bearing steel specs; discrepancies lead to 7225.99 reclassification
• Document hot-rolled state only—no annealing or pickling beyond standard hot-rolling, as 'further worked' per chapter notes shifts classification
• Avoid rust/discoloration claims at entry; no duty allowance per chapter note, so inspect pre-shipment
