AISI 52100 Hot-Rolled Ball-Bearing Steel Strip
Hot-rolled flat-rolled strip of AISI 52100 alloy steel, measuring 250 mm wide and 5 mm thick, not further worked beyond hot-rolling. Classified under HTS 7226.91.25.30 as flat-rolled product of other alloy steel, width under 300 mm, of ball-bearing steel per U.S. note (h) with specific carbon (0.95-1.13%), chromium (1.25-1.65%), and low sulfur/phosphorus content. Used primarily for manufacturing high-precision ball bearings.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If high-speed steel composition
High-speed tool steels (with tungsten/molybdenum/vanadium exceeding ball-bearing limits) fall under separate hot-rolled tool steel subheading.
If not alloy steel (≤10% total alloying elements)
Non-alloy steel flat-rolled products of similar width/thickness classify in Chapter 72 heading 7211 for hot-rolled non-alloy steel.
If clad, coated, or polished
Any 'further worked' surface treatment per Chapter 72 note (polishing, coating, cladding) shifts to cold-rolled or clad alloy steel headings.

Import Tips & Compliance
• Certify at entry that steel meets U.S. note (h) ball-bearing steel specs (e.g
• 0.95-1.13% C, 1.25-1.65% Cr, ≤0.03% S/P) with mill test certificates
• Verify width <300 mm and hot-rolled only (no cold-rolling, polishing, or coatings) to avoid reclassification as further worked
• Include heat analysis reports; common pitfall is mislabeling tool steel variants not meeting exact ball-bearing elemental limits
