Products classified under HTS 7305.90.50.00
Alloy Steel Large Diameter Welded Pipe
A welded pipe made from alloy steel with a circular cross-section and external diameter exceeding 406.4 mm, used primarily for oil and gas transmission pipelines. It falls under HTS 7305.90.50.00 as it is an other tube or pipe of alloy steel, not further worked, meeting the size criteria for large-diameter applications.
Alloy Steel Spiral Welded Pipeline Tube
Spiral welded tube of alloy steel, circular cross-section over 406.4 mm OD, designed for long-distance natural gas pipelines. Classified in 7305.90.50.00 as an other welded pipe of alloy steel for large-diameter applications, not seamless or further processed.
Alloy Steel Submerged Arc Welded Pipe
Large-diameter pipe produced via submerged arc welding from alloy steel, with OD >406.4 mm for water transmission mains. It qualifies for HTS 7305.90.50.00 as other riveted or similarly closed tubes of alloy steel in the specified size range.
Alloy Steel Large Diameter LSAW Pipe
Longitudinally submerged arc welded (LSAW) alloy steel pipe exceeding 406.4 mm OD, used in offshore oil platforms. Falls under 7305.90.50.00 for other large circular cross-section pipes of alloy steel, welded construction.
Alloy Steel ERW Large Transmission Pipe
Electric resistance welded (ERW) alloy steel pipe with circular cross-section OD >406.4 mm for crude oil transmission lines. Classified in HTS 7305.90.50.00 as other tubes and pipes of alloy steel meeting the large diameter specification.
Alloy Steel DSAW Water Main Pipe
Double-sided submerged arc welded (DSAW) pipe of alloy steel, OD exceeding 406.4 mm, for municipal water distribution mains. It is an other welded pipe under HTS 7305.90.50.00 due to alloy composition and large circular cross-section.
Alloy Steel HFW Oil Pipeline Tube
High-frequency welded (HFW) alloy steel tube with external diameter >406.4 mm for refined oil product pipelines. Meets HTS 7305.90.50.00 criteria as other large-diameter welded pipes of alloy steel.
