AISI 4140 Hot-Rolled Alloy Steel Coil
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.

This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chromium content is 0.3% or less
Low-alloy compositions fall under circular cross-section iron/non-alloy steel hot-rolled bars/rods in coils, per chapter alloy steel threshold.
If hot-rolled in straight lengths instead of coils
Same alloy steel bars/rods but not in irregularly wound coils classify under the straight-length subheading.
If silicon-manganese alloy steel
Specific silicon-manganese free-cutting steels have dedicated subheadings separate from 'other alloy steel'.

Import Tips & Compliance
• 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
