Cold-Rolled AISI 4130 Alloy Steel Strip from China
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.

Import Tips
• 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
