Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ball-bearing steel per note (h)
Steels exactly matching ball-bearing composition (0.95-1.13% C, 1.25-1.65% Cr, low impurities) have separate high-speed classification.
If over 600 mm width
Cold-rolled alloy steel sheets ≥600 mm wide shift to heading 72.14 from narrow 7226.
If semi-finished billets
Non-flat rolled or semi-finished tool steel shapes classify as billets in 7229.20.

Import Tips & Compliance
• Differentiate from ball-bearing steel note (h); 52100 typically exceeds those tight elemental bands
• Mill certificates must show cold-reduction gauges and flatness tolerances
