Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as hot-rolled flat bars
Hot-rolled into bar form moves from semi-finished (7224) to worked bars/rods (7228).
If ground or machined on surfaces
Any grinding or finishing triggers 'further worked' classification in 7225.
If carbon content below tool steel threshold
Non-tool alloy steels with lower carbon/chromium go to 7214 for semi-finished products.
