Last updated: August 2026 dataFlat-rolled iron or non-alloy steel with embossed or raised surface patterns — commonly called 'checkered plate' or 'tread plate' — is classified here when hot-rolled and not further clad, plated, or coated. The relief pattern provides anti-slip properties, making this product a staple in flooring, ramps, stair treads, and vehicle decking. The US lines under this heading cover both coil and non-coil forms across multiple thickness bands, from over 10 mm (7208403030) down to under 3 mm (7208406030). Canada leads supply, with Italy, India, China, and Mexico also among the top sources; imports from China are subject to Section 301 tariffs in addition to Section 232 measures.

The raised pattern must be formed during the hot-rolling process itself — not applied afterward by stamping or embossing as a secondary operation. If the pattern is added post-rolling, the product may not qualify under 720840 and could fall under a different heading. Importers should confirm with the mill that the relief pattern is integral to the rolling process and document this in the commercial invoice or mill certificate.
Imports of flat-rolled steel products from China are subject to both Section 232 tariffs and Section 301 tariffs. The combined effect significantly increases the landed cost relative to other origins. Importers should calculate the full duty stack — including any applicable antidumping or countervailing duties — before finalizing sourcing decisions involving Chinese-origin tread plate.
