AISI 4140 Alloy Steel Round Bar from Canada

A hot-rolled round bar made from AISI 4140 chromium-molybdenum alloy steel, commonly used for shafts, gears, and axles in machinery. It falls under HTS 7228.60.60.00 as a non-cold-formed bar of other alloy steel, not meeting specific alloy steel definitions in chapter notes like tool steel or ball-bearing steel. The product is supplied in straight lengths without cold-forming processes.

Import Tips

• Provide mill test certificates confirming alloy composition to verify classification under 'other alloy steel' and avoid reclassification as tool steel

• Ensure documentation specifies hot-rolled or forged production method to distinguish from cold-formed products under different subheadings

• Check for minimum alloying elements (e.g

• chromium >0.9%, molybdenum) as per HTS Chapter 72 definitions to prevent misclassification
