Longitudinally Welded Alloy Steel Pipe for Oil Pipelines from Japan
This large-diameter pipe, with an external diameter over 406.4 mm, is longitudinally welded from alloy steel sheets and used in oil and gas transmission pipelines. It falls under HTS 7305.31.60.90 as it meets the criteria for other longitudinally welded tubes of alloy steel with circular cross-section exceeding 16 inches in diameter. The alloy composition provides enhanced strength and corrosion resistance for high-pressure applications.

Import Tips
• Verify alloy steel composition meets ASTM A335 or equivalent standards; provide mill test certificates for customs verification
• Ensure longitudinal weld seam is documented and inspected per API 5L standards to avoid misclassification as seamless
