Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If qualifying as high-strength steel
Products with yield point ≥275 MPa (thickness <3 mm) or ≥355 MPa (≥3 mm) per US Note 72(a) classify as high-strength steel.
If carbon steel, not alloy
Lacks minimum alloying elements (e.g., <0.3% Cr, <0.25% Mo) required for alloy steel classification under Chapter 72 Note 1(f).
If cold-rolled
Cold-rolling constitutes 'further worked' per US Note definition, moving to cold-rolled alloy steel provisions.

Import Tips & Compliance
• Provide mill test certificate confirming alloy composition (e.g
• Cr 0.8-1.1%, Mo 0.15-0.25%) to verify not stainless or high-strength steel
• Ensure accurate thickness measurement (<4.75 mm) and width (≥600 mm) documentation to avoid reclassification to 7225.30.30 or narrower products
• Declare as 'not further worked than hot-rolled' with surface inspection reports; any polishing or coating shifts to 7225.99
