7228.30.80.41/AISI 4140 Hot-Rolled Alloy Steel Round Bar 100 mm Diameter/Mexico

AISI 4140 Hot-Rolled Alloy Steel Round Bar 100 mm Diameter from Mexico

AISI 4140 chromium-molybdenum alloy steel round bar, hot-rolled with a diameter of 100 mm, used in oilfield drilling tools and heavy machinery components. Classified under HTS 7228.30.80.41 as other hot-rolled alloy steel bars not further worked, with cross-section between 76-152 mm. Meets alloy steel definition due to chromium and molybdenum content exceeding Chapter 72 note thresholds.

Import Tips

• Provide mill test certificate confirming alloy composition (Cr, Mo content) and hot-rolled condition to avoid reclassification as carbon steel

• Ensure accurate dimensional measurement documentation; CBP measures cross-section upon entry to verify 76-152 mm range

• Declare as 'not further worked' - any polishing or coating shifts to 7228.60 or higher duty subheadings
