Cold-Finished 4140 Alloy Steel Round Bar 250mm
A cold-finished round bar made from 4140 chrome-molybdenum alloy steel with a diameter of 250 mm, used in heavy machinery shafts and axles. Classified under HTS 7228.50.50.70 as other bars and rods of alloy steel, not further worked than cold-formed or cold-finished, exceeding 228 mm cross-section. Meets alloy steel definition due to chromium and molybdenum content.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of non-alloy steel
Non-alloy steel bars fall under Chapter 72 heading 7224, lacking specified alloying elements like chromium or molybdenum.
If hot-rolled instead of cold-finished
Hot-rolled bars (not cold-formed/finished) are classified under 7228.30, as this code specifically requires cold-working.
If angles, shapes or sections rather than round bars
Structural shapes like angles or channels of alloy steel go to 7228.70, while round/square bars are under 7228.50.

Import Tips & Compliance
• Provide mill test certificates confirming alloy composition (Cr, Mo content) and cold-finished status to avoid reclassification
• Verify cross-sectional diameter exceeds 228 mm with precise measurements; common pitfall is mismeasurement leading to wrong subheading
• Declare as 'not further worked' - no coatings or polishing beyond cold-finishing allowed under this code
