Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ball-bearing steel composition
Matches exact element ranges in US Note 72(h) for bearing applications.
If not in coils, plate form
Universal mill plate specs met per Note 72(b).
If rolled bars not flat
Form factor closer to bars/rods than flat-rolled sheet.

Import Tips & Compliance
• Certify not ball-bearing steel per US Note 72(h); 9310 has higher Ni content
• Use calibrated gauges for thickness verification <4.75 mm
• Label coils clearly with HTS and grade to speed customs exam
