Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If further worked with surface treatment
Any polishing, coating, or cladding moves to 'other alloy steel, not further worked than cold-rolled' per chapter note.
If not alloy steel (≤10% total alloying elements)
Falls to plain carbon steel hot-rolled coils if alloy content doesn't meet Chapter 72 alloy steel threshold.
If high-strength steel per US Note (a)
Thickness ≥3mm with minimum yield point 355 MPa qualifies as high-strength steel.

Import Tips & Compliance
• Provide mill test certificate confirming alloy composition excludes tool steel or high-strength steel definitions
• Verify product meets 'not further worked than hot-rolled' - no polishing, coating, or cladding allowed
• Check width ≥600mm and thickness ≥4.75mm measurements at entry to avoid reclassification
