Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of high-strength steel specification
High-strength steel (yield point 355+ MPa for ≥3mm thick) moves to 7226.91 per Chapter 72 Note (a).
If containing 4-10.5% chromium, <0.3% carbon
Qualifies as heat-resisting steel per Chapter Note (g), classified separately from other alloy steel.
If further worked into U-sections or profiles
Surface treatments beyond cold-rolling (coated/painted) or formed into sections change to Chapter 73.

Import Tips & Compliance
• Provide mill test certificate confirming alloy steel composition (e.g
• Cr 0.8-1.1%, Mo 0.15-0.25%) excluding tool steel elements
• Declare exact width (<600mm) and confirm not further worked beyond cold-rolling to avoid reclassification
• Watch Section 232 tariffs; ensure melt-and-pour documentation if derivative aluminum/steel aluminum product claims apply
