304H Stainless Heat-Resisting Steel Cold-Reduced Plate
Cold-rolled 304H stainless steel plate under 4.75 mm thick and 600+ mm wide, qualifying as heat-resisting per US note (g) due to low carbon and chromium content. Designed for elevated-temperature service in petrochemical processing equipment. Not further worked beyond cold-reduction.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If electrical sheet quality
Cold-rolled non-alloy steel with grain-oriented properties classified under heading 7213.
If further worked (e.g., coated)
Chapter note defines 'further worked' including metal coating, shifting to Chapter 72 heading 7226.
If hot-rolled rather than cold-rolled
Hot-rolled alloy steel (not cold-reduced) falls under preceding subheading 7225.40.

Import Tips & Compliance
• Submit chemical analysis showing <0.3% C and 4-10.5% Cr to distinguish from standard stainless
• Document cold-rolling process; any polishing moves to 'further worked' subheadings
• Check width measurement at narrowest point to confirm ≥600 mm requirement
