Import Tips
• Provide engineering drawings showing roll dimensions and mounting for rolling mills to substantiate classification
• Conduct metallurgical analysis to confirm gray iron microstructure, preventing shifts to ductile iron categories
• Declare as complete rolls, not parts, to avoid breakdown into Chapter 84 accessories
