Products classified under HTS 7228.60.10.30
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.
SUJ2 Japanese Ball-Bearing Steel Flat Bar
Flat bar stock of SUJ2 high-carbon chrome bearing steel equivalent to AISI 52100, meeting all Chapter 72 note (h) criteria for ball-bearing tool steel. Under HTS 7228.60.10.30 as other bars/rods (not angles/shapes) of this specific grade, used in precision bearing components.
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.
