Import Tips
• Verify seamless manufacturing process with mill test certificates to avoid misclassification as welded under 7306
• Include exact OD and wall thickness measurements in commercial invoice to match statistical suffix
• Obtain material composition certification confirming nonalloy steel to prevent reclassification to alloy steel headings
