Import Tips
• Submit positive material identification (PMI) test results proving duplex stainless microstructure to prevent undervaluation disputes
• Bundle in quantities matching API joint lengths (e.g
• 40ft doubles) to evidence OCTG drill string assembly
• Avoid 'coupling not integral' errors by including assembly diagrams showing field-makeup specifications
