Import Tips & Compliance
• Document hot-extrusion process to distinguish from forged products under 7228.40
• Verify not qualifying as high-strength steel per note (a); yield >355 MPa may trigger different rates
• Include heat treatment records if normalized, but avoid finish-worked descriptions

AISI 4140 Hot-Rolled Alloy Steel Round Bar
AISI 4140 is a chromium-molybdenum alloy steel round bar produced by hot-rolling, used for shafts, gears, and axles in machinery. It falls under HTS 7228.30.80 as other bars and rods of alloy steel, not further worked than hot-rolled, hot-drawn or extruded. The alloy composition exceeds simple carbon steel definitions and lacks special alloy steel specifications from chapter notes.
