Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Hot-rolled base with hot-dip zinc coating classified differently from cold-rolled electrolytic.
If thickness >10mm
Thicker plates over 10 mm shift to Chapter 72 plate/plate category regardless of coating.
If alloy steel composition
Alloy steel versions use Chapter 72 alloy headings even with electrolytic plating.
