Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formed into angles, shapes, or sections
Same steel in angle/shape profiles moves to 7228.40 instead of round/square/flat bars
If high-strength steel per note (a)
High-strength alloy steel bars with minimum yield point specs classify under 7228.30.10
If hot-rolled flat products ≤150mm wide
Narrower flat-rolled products may classify under Chapter 72 heading 7208 if not bar form

Import Tips & Compliance
• Include Japanese JIS certification alongside AISI equivalence documentation; verify width/thickness doesn't qualify as 'universal mill plate' under note (b); monitor for AD/CVD on specific bearing steel imports

AISI 52100 Ball-Bearing Steel Round Bar
A precision-ground round bar made from AISI 52100 alloy steel, specifically formulated for ball-bearing applications with controlled carbon (0.95-1.13%), chromium (1.25-1.65%), and low sulfur/phosphorus levels as defined in HTS Chapter 72 note (h). This falls under HTS 7228.60.10.30 as other bars and rods of tool steel (not high-speed) of ball-bearing steel. It is hot-rolled or forged into bar form without further working beyond basic surface treatments.
52100 Chrome Alloy Steel Hexagonal Bar
Hexagonal profile bar produced from 52100 ball-bearing steel meeting Chapter 72 note (h) specifications for bearing manufacturing, with precise low impurity levels and chromium content. Classified under HTS 7228.60.10.30 as other bars/rods of tool steel of ball-bearing composition, not high-speed steel. Typically used for bearing races and rolling elements.
GCr15 Ball-Bearing Steel Square Bar
Square cross-section bar of GCr15 (Chinese equivalent to 52100) ball-bearing steel with composition certified to Chapter 72 note (h): 0.95-1.13% C, 1.25-1.65% Cr, minimal S/P. HTS 7228.60.10.30 covers these tool steel bars specifically for bearing production, distinguished from general alloy steel.
100Cr6 Ball-Bearing Steel Rod
Drawn or ground rod of 100Cr6 (DIN equivalent 52100) ball-bearing steel precisely matching Chapter 72 note (h) composition for superior fatigue resistance in bearings. HTS 7228.60.10.30 applies to these other bars/rods of tool steel, excluding high-speed grades and hollow drill rods.
