AISI 52100 Hot-Rolled Ball-Bearing Steel Plate from China
Flat-rolled alloy steel plate of 52100 grade, specifically formulated as ball-bearing steel with 0.95-1.13% carbon and 1.25-1.65% chromium, hot-rolled to a thickness under 4.75 mm and width over 600 mm, not in coils. It falls under HTS 7225.40.51.30 because it meets the precise chemical composition for ball-bearing steel per U.S. Note (h) and is not further worked beyond hot-rolling.

Import Tips
• Certify exact chemical composition matching U.S
• Note (h) for ball-bearing steel (e.g
• 0.95-1.13% C, 1.25-1.65% Cr) with mill test reports to avoid reclassification
• Measure thickness precisely under 4.75 mm and width over 600 mm; provide gauge certifications as CBP often verifies dimensions
• Ensure no 'further worked' treatments like polishing or coating per chapter notes, or it shifts to 7225.99 or 7226 headings
