Import Tips

Certify exact alloy composition (e.g

Cr, Mo content) via mill test reports to confirm alloy steel status; ensure no further working like polishing occurred post-forging to avoid reclassification; declare forged condition accurately to prevent disputes over 'further worked' per Chapter 72 notes
