Import Tips

• Provide mill test certificates confirming alloy composition (e.g

• 0.38-0.43% C, 0.8-1.1% Cr, 0.15-0.25% Mo) to avoid reclassification

• Ensure product is in irregularly wound coils and hot-rolled; uncoiled or cold-rolled shifts to different subheadings

• Declare exact diameter and coil weight to match statistical reporting; common pitfall is misstating as concrete reinforcing bars
