AISI 4140 Hot-Rolled Alloy Steel Round Bar 200mm
AISI 4140 chromium-molybdenum alloy steel bar, hot-rolled with a diameter of 200 mm, used for heavy machinery shafts and axles. Classified under HTS 7228.30.80.45 as other bars and rods of alloy steel, not further worked than hot-rolled, with cross-section 152-228 mm. Meets alloy steel definition due to chromium and molybdenum content exceeding Chapter 72 note thresholds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cross-section under 152 mm
Diameter threshold determines subheading within same hot-rolled alloy bars category
If cold-rolled, drawn, or extruded
Cold-worked bars fall under different processing subheading per heading structure
If not qualifying as alloy steel per Chapter 72 notes
Non-alloy steel bars with similar dimensions classified in Chapter 72 heading 7214

Import Tips & Compliance
• Certify exact alloy composition (Cr, Mo content) matching AISI 4140 specs to avoid reclassification; measure diameter precisely as <152mm shifts to smaller size subheading; ensure mill test reports confirm hot-rolled only, no further working like polishing
