Import Tips & Compliance
• Boron content (<0.003%) doesn't affect alloy steel classification
• Ensure production records show hot-rolling only, no cold reduction
• Common for automotive; segregate from carbon steel shipments

AISI 4140 Alloy Steel Round Bar
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.
