Import Tips
• Duplex grades require chemical analysis certificates proving chromium/nickel/molybdenum content for stainless classification
• Confirm no special processing (e.g
• solution annealing) that might qualify as seamless under 7304
• Monitor quarterly AD/CVD updates for duplex stainless from Italy, Spain, or Korea
