Import Tips
• Include chemical analysis report specifying chromium/molybdenum content to prove alloy steel status
• Label as 'seamless' on commercial invoice; customs may inspect for weld seams
• Avoid misdeclaration as drill pipe—ensure end-use statement if applicable to prevent anti-dumping scrutiny
