Import Tips
• Provide mill test certificates confirming alloy composition meets Chapter 72 definitions for alloy steel
• Verify exact diameter measurement exceeds 228 mm to avoid misclassification into smaller size subheadings
• Check for any surface treatments that could classify as 'further worked' under Chapter 72 notes
