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
