Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If universal mill plate per US Note 72(b)
Specific width 150-1250mm and thickness ≥4mm rolled on four faces qualifies for separate statistical breakout.
If further worked (e.g., oiled or pickled)
Chemical surface treatments like phosphatizing convert to 'further worked' category in following heading.
If for bulk industrial packs vs retail
If carbon steel (not alloy) and leaded for machining, moves to specific carbon steel subheading.

Import Tips & Compliance
• Document hot-rolling process only; any burnishing/polishing disqualifies as 'further worked' per US Note, shifting to 7225.99
• Include chemical analysis reports showing alloy elements below tool steel/heat-resisting thresholds defined in US Notes 72(e)-(g)
