AISI 52100 Cold-Rolled Ball Bearing Steel Strip
Flat-rolled strip of AISI 52100 alloy steel, cold-rolled to precise thickness under 3mm and width less than 300mm, specifically formulated for ball bearing production with controlled carbon (0.95-1.13%), chromium (1.25-1.65%), and low impurities. It falls under HTS 7226.92.3030 as not further worked than cold-rolled, of tool steel meeting ball-bearing steel definition, and width under 300mm. This high-purity steel ensures minimal defects in bearing raceways and rolling elements.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width measures 300mm or more
Same cold-rolled ball-bearing steel but wider dimension places it in the 300mm+ subheading within the same tool steel category.
If supplied hot-rolled instead of cold-rolled
Hot-rolled ball-bearing steel flat products fall under Chapter 72 heading 7225 for hot-rolled alloy steel, not cold-rolled.
If surface is polished or coated after cold-rolling
Any polishing, coating, or chemical treatment constitutes 'further worked' per Chapter 72 note, moving to 'other than cold-rolled' categories.

Import Tips & Compliance
• Provide mill test certificate confirming ball-bearing steel composition per US Note (h) with exact elemental analysis including C 0.95-1.13%, Cr 1.25-1.65%
• Verify cold-rolled condition only - no polishing, coating, or heat treatment beyond rolling qualifies as 'further worked' per Chapter 72 notes
• Measure width precisely before entry; strips over 300mm shift to 7226.92.3050, changing duty rates
