Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not in ingot or primary form but as semi-finished
Semi-finished products like blooms or billets fall under 7224.90, distinct from primary ingot forms.
If semi-finished product of high-strength steel
High-strength steel semi-finished products per note (a) are classified in heading 7207, not alloy steel in 7224.
If further worked with polishing or coating
Chapter note defines 'further worked' surface treatments moving it from primary forms to bars/rods in 7228.
