Cold-Finished 4140 Alloy Steel Round Bar 100 mm Diameter from Mexico
A cold-finished round bar made from 4140 chrome-molybdenum alloy steel with a 100 mm diameter, used in machinery and automotive axles. Classified under HTS 7228.50.5040 as other bars and rods of alloy steel, not further worked than cold-formed or cold-finished, with cross-section between 76-228 mm. Meets alloy steel definition due to chromium and molybdenum content exceeding chapter note thresholds.

Import Tips
• Certify exact alloy composition (Cr, Mo content) matching 4140 specs to confirm alloy steel status per Chapter 72 notes
• Verify cold-finishing process documentation; hot-rolled bars shift to 7228.30 headings
• Measure cross-section precisely (76-228 mm) to avoid duty shifts to smaller/larger size subheadings
