Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heat-resisting steel per note (g)
Low-carbon, high-chromium compositions qualify for heat-resisting steel subheading
If true ingot form before primary processing
Less processed ingots classify under heading 7206 rather than semi-finished
If hot-rolled bars after further processing
Rolling into bar form changes from semi-finished to finished product heading
