Import Tips
• Require NDT reports (ultrasonic or radiographic) as per ASTM A106; customs may inspect for seamless integrity
• Label with heat number, grade, and dimensions; missing markings can trigger FDA-equivalent scrutiny for industrial safety
• Avoid misdeclaration as drill pipe (7304.21) by providing non-drilling end-use affidavits
