Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of thickness 4.75 mm or more
Thicker cold-rolled alloy steel sheets classify under 7225.40, same width requirement.
If width under 600 mm
Narrower cold-rolled alloy steel products fall under heading 7226.
If in coils rather than cut-to-length
Coiled flat-rolled alloy steel classifies under heading 7208 regardless of width.

Import Tips & Compliance
• Submit detailed chemical composition reports proving alloy status (Ni, Cr, Mo content) per Chapter 72 notes
• Measure width and thickness precisely; products ≥4.75mm shift to different statistical suffixes
• Avoid reclassification pitfalls by ensuring no phosphatizing or other chemical treatments occurred post-rolling
