AISI 52100 Ball-Bearing Steel Hot-Rolled Coil from China
Hot-rolled bars and rods in irregularly wound coils made from ball-bearing steel conforming to the precise chemical composition specified in HTS Chapter 72 note (h), including 0.95-1.13% carbon and 1.25-1.65% chromium. These are not tempered, not treated, and not partly manufactured, used primarily for manufacturing high-precision ball bearings. Classified under 7227.90.1030 due to their specific alloy composition meeting the ball-bearing steel definition and hot-rolled coil form.

Import Tips
• Provide mill test certificates confirming exact chemical composition meets Chapter 72 note (h) for ball-bearing steel to avoid reclassification
• Document that material is not tempered, treated, or partly manufactured; any heat treatment voids this classification
