Cold-Rolled AISI 4130 Alloy Steel Strip
Thin flat-rolled strip of AISI 4130 chromium-molybdenum alloy steel, cold-rolled to a thickness not exceeding 0.25 mm and width under 300 mm. This product is not further worked beyond cold-rolling and falls under HTS 7226.92.70.50 as other alloy steel flat-rolled products of less than 600 mm width, specifically in the thin cold-rolled category.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated with plastics or painted
Surface treatments like plastic coating or painting qualify as 'further worked' per Chapter 72 notes, shifting to 7226.99.
If width 300-600 mm
Width dimension determines subheading; products 300 mm and wider but under 600 mm fall under 7226.92.30.
If not alloy steel (e.g., plain carbon steel)
Lacks specified alloying elements required for Chapter 72 alloy steel classification, moving to Chapter 72 non-alloy.

Import Tips & Compliance
• Provide mill test certificate confirming alloy composition meets AISI 4130 specs and dimensions fit 7226.92.70.50 criteria
• Verify cold-rolling process documentation to distinguish from hot-rolled (7226.91) or further worked products (7226.99)
• Watch for thickness measurement disputes; use calibrated tools as CBP tolerances are strict for ≤0.25 mm classification
