Import Tips
• Provide chemical composition analysis showing minimum 12.5% Cr content to confirm stainless steel status
• For high-value shipments, secure marine insurance covering API grade rejection risks during customs inspection
• Avoid misdeclaration as 'tubing'—casing specifically lines the wellbore, distinct from production tubing
