Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of silicon-electrical steel grain-oriented
Silicon-electrical steels have separate alloy/manufacturing classification.
If universal mill plate form
Universal mill plates (150-1250 mm wide, ≥4 mm thick, specific rolling) per Note (b).
If width under 600 mm
Width threshold splits 7225 (≥600 mm) from 7208 narrower alloy steel products.

Import Tips & Compliance
• Include sulfur/phosphorus analysis (<0.03%) as CBP targets ball-bearing steel's purity requirements
• Label as 'not further worked' explicitly; any burnishing or oxidation treatment reclassifies
• Use AD/CVD-free suppliers; this HTS avoids many steel tariffs but verify country of melt/pour

AISI 52100 Hot-Rolled Ball-Bearing Steel Plate
Flat-rolled alloy steel plate of 52100 grade, specifically formulated as ball-bearing steel with 0.95-1.13% carbon and 1.25-1.65% chromium, hot-rolled to a thickness under 4.75 mm and width over 600 mm, not in coils. It falls under HTS 7225.40.51.30 because it meets the precise chemical composition for ball-bearing steel per U.S. Note (h) and is not further worked beyond hot-rolling.
