Import Tips

Certify exact elemental composition matching Chapter 72 note (h) for ball-bearing steel to avoid reclassification

Provide mill test certificates confirming hot-rolled state and no further working like polishing or coating

Watch for width measurement disputes; ensure documentation proves 300-600 mm range
