Cold-Reduced 100Cr6 Ball Bearing Steel Strip
EN 100Cr6 (equiv. AISI 52100) cold-reduced flat-rolled steel strip for manufacturing precision ball bearings, conforming to HTS Chapter 72 ball-bearing steel definition with controlled low sulfur/phosphorus (≤0.03%) and silicon (0.18-0.37%). Width measures 350 mm, cold-rolled only without further surface treatments, fitting 7226.92.1030 for tool steel of alloy steel over 300 mm wide. Used primarily for bearing rings and rolling elements.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further worked (e.g., polished or coated)
Any polishing, coating, or chemical treatment post-rolling constitutes 'further worked' per Chapter note, moving to 7226.92.3000.
If of heat-resisting steel composition
Heat-resisting alloy steels (low C, 4-10.5% Cr per note g) classify under 7228.70 regardless of end use.
If sold as hot-rolled rather than cold-rolled
Hot-rolled alloy steel sheets over 300mm wide fall under heading 7212, prior to cold-reduction process.

Import Tips & Compliance
• Provide EN 100Cr6 or AISI 52100 material certs proving ball-bearing elemental specs; mismatches lead to 7226.99 reclassification
• Measure and declare width precisely (300-600mm); edge trimming may affect classification if reducing width below threshold
• Avoid packaging that implies further working; bulk coils ok, but retail-packed may trigger 'further worked' review
