Import Tips
• Provide chemical composition certificates proving >10.5% chromium content for stainless steel classification
• Label as 'drill pipe' with drilling specs to distinguish from tubing; mislabeling leads to reclassification
• Check for upset ends or friction welds, which are allowed but must be documented to prevent heading to parts
