Import Tips
• Verify alloy steel composition via mill test certificates to confirm classification under 7305.39 vs carbon steel 7305.31
• Ensure weld seam inspection reports (e.g
• ultrasonic testing) are included in documentation for customs valuation
• Avoid misclassification as OCTG by providing end-use affidavits for line pipe applications
