Import Tips
• Obtain mill test certificates verifying high-nickel alloy composition to avoid reclassification to standard stainless steel headings
• Ensure seamless certification via non-destructive testing reports, as welded pipes fall under Chapter 73 heading 7305
• Declare exact nickel content percentage; customs may require chemical analysis for high-nickel verification
