Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heat-resisting tool steel
Different tool steel categories (note g) classify separately from ball-bearing.
If stainless steel composition
Any stainless qualities shift to 72.13 stainless bars.
If not cold-finished (hot-rolled)
Processing state determines cold-finished vs other subheadings.

Import Tips & Compliance
• Differentiate from welding wire; bearing quality has stricter purity specs
• Specify diameter; finer than 5mm may face wire classification scrutiny
• Retain drawing passes documentation to prove cold-formed status
