Import Tips

Provide mill test certificates confirming alloy composition (e.g

chromium >0.9%, molybdenum >0.15%) to distinguish from plain carbon steel under 7213/7214

Declare exact coil winding as 'irregularly wound' vs straight lengths to avoid misclassification into 7227.90.30; inspect for deformation
