AISI 4140 Hot-Rolled Alloy Steel Coil from China
Hot-rolled bars and rods of AISI 4140 chromium-molybdenum alloy steel, wound in irregularly shaped coils, used for manufacturing shafts and gears. This product falls under HTS 7227.90.60 as it is hot-rolled alloy steel (not stainless), not concrete reinforcing, and in irregularly wound coils. The alloy composition exceeds plain carbon steel limits, qualifying it as 'other alloy steel' per chapter notes.

Import Tips
• Provide mill test certificates confirming alloy composition (e.g
• chromium >0.9%, molybdenum >0.15%) to distinguish from plain carbon steel under 7213/7214
• Declare exact coil winding as 'irregularly wound' vs straight lengths to avoid misclassification into 7227.90.30; inspect for deformation
