ASTM A691 Alloy Steel LSAW Line Pipe from Japan
Longitudinally submerged arc welded pipe per ASTM A691 specifications, made from alloy steel grades like 1-1/4Cr, with OD exceeding 406.4 mm for sour gas service in oilfield pipelines. The alloy enhances corrosion resistance in harsh environments. HTS 7305.11.50.00 applies to its LSAW construction and alloy steel line pipe designation.

Import Tips
• Submit chemical composition analysis confirming alloy elements (e.g
• chromium >1.00%) to distinguish from carbon steel equivalents
• Ensure end-use declarations specify oil/gas pipeline application to avoid general pipe headings
• Pre-clear with CBP rulings for normalized/heat-treated pipes, as processing state can affect valuation
