Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thickness of 4.75 mm or more
Thicker cold-rolled alloy steel plates ≥4.75 mm are classified in 7225.40, separating by thickness threshold.
If considered high-strength steel per US note 72(a)
High-strength steel meeting yield point criteria (thickness ≥3mm, minimum 355 MPa) shifts to specific provisions under heading 7208.
If grain-oriented electrical steel
Electrical alloy steels with specific magnetic properties fall under grain-oriented provisions in 7225.11.
