7227.90.20.30/AISI 52100 Ball-Bearing Steel Hot-Rolled Coil/China

AISI 52100 Ball-Bearing Steel Hot-Rolled Coil from China

Hot-rolled bars and rods in irregularly wound coils made from AISI 52100 alloy steel, specifically formulated for ball-bearing production with precise carbon (0.95-1.13%), chromium (1.25-1.65%), and low sulfur/phosphorus content per US note (h). This falls under HTS 7227.90.20.30 as other tool steel of ball-bearing quality, hot-rolled in coils. Ideal for manufacturing high-precision bearing components requiring superior hardness and fatigue resistance.

Import Tips

• Provide mill test certificates confirming ball-bearing steel composition per US Note (h) to avoid reclassification

• Ensure coils are irregularly wound and hot-rolled; cold-drawn products shift to Chapter 72 headings 7228-7229

• Declare exact alloy analysis to prevent disputes over tool steel vs. other alloy steel categories
