Seamless ASTM A106 Grade B Steel Pipe from Japan

A seamless carbon steel pipe manufactured to ASTM A106 Grade B specifications, featuring a circular cross section with an outside diameter of 168.3 mm and wall thickness of 25 mm. It is designed for high-temperature service in piping systems for oil refineries and power plants. Classified under HTS 7304.39.0044 due to its seamless construction, nonalloy steel material, specified diameter range exceeding 114.3 mm but less than 190.5 mm, and wall thickness of 19 mm or more.

Import Tips

Verify seamless certification via mill test reports (MTRs) as welded pipes classify under Chapter 73 headings like 7306

Measure exact OD and wall thickness to confirm 114.3-190.5 mm OD and ≥19 mm wall; small deviations shift to adjacent subheadings

Include chemical composition analysis proving nonalloy steel (≤0.3% alloying elements) to avoid Chapter 72 alloy steel headings
