Import Tips
• Label shipments clearly as 'hot-rolled alloy steel bar' to differentiate from cold-drawn products and avoid duty reassessment
• Include chemical analysis reports showing elements like Ni 1.65-2%, Cr 0.4-0.8% to confirm 'other alloy steel' status
• Verify product not further worked (e.g
• no polishing/coating) as per chapter note, or it may shift to 7228.70
