Forged Alloy Steel Round Bar 4140
A forged round bar made from AISI 4140 chromium-molybdenum alloy steel, not further worked beyond forging, used primarily for shafts and gears in machinery. It falls under HTS 7228.40.00.00 as other bars and rods of alloy steel that are only forged, without additional processing like rolling or surface treatment. The alloy composition exceeds standard carbon steel limits, qualifying it as alloy steel per Chapter 72 notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hot-rolled instead of forged
Hot-rolled alloy steel bars fall under heading 7224, as forging is a distinct process from rolling per tariff distinctions.
If cold-formed or finished
Cold-formed bars are classified separately from merely forged products under 7228.30.
If machined into finished articles
Machined or further worked forged blanks become articles of iron or steel under Chapter 73.

Import Tips & Compliance
• Certify exact alloy composition (e.g
• Cr, Mo content) via mill test reports to confirm alloy steel status; ensure no further working like polishing occurred post-forging to avoid reclassification; declare forged condition accurately to prevent disputes over 'further worked' per Chapter 72 notes
