AISI 4140 Cold-Rolled Alloy Steel Plate 6mm Thick

This flat-rolled plate made from AISI 4140 chromium-molybdenum alloy steel measures 6mm thick and 800mm wide, cold-rolled but not further worked beyond reduction. It falls under HTS 7225.50.60.00 as an other alloy steel product wider than 600mm and thicker than 4.75mm, without additional surface treatments like coating or polishing. Commonly used in machinery and structural applications requiring high strength.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7225.40.70.00Same rate: 35%

If hot-rolled instead of cold-rolled

Hot-rolled alloy steel plates of similar thickness classify under 7225.40, as cold-reduction changes the 'not further worked than' status.

7212.50.00.00Same rate: 35%

If not qualifying as 'other alloy steel' per note (e.g., low alloy content)

Non-alloy or low-alloy steels fall under Chapter 72 heading 7212 for cold-rolled flat products.

7225.99.00Same rate: 35%

If further worked with coatings or cladding

Any surface treatment beyond cold-rolling (per chapter note) like metal coating shifts to 'further worked' subheadings.

Import Tips & Compliance

Provide mill test certificates confirming alloy composition and cold-rolling process to verify classification under 'other alloy steel'

Ensure accurate thickness measurement documentation as products 4.75mm and thicker fall here; thinner may shift to 7225.50.40

Avoid common pitfalls like misdeclaring further worked surfaces (e.g

polished), which moves to 7225.99 headings
