Longitudinally Welded Alloy Steel Pipe for Oil Pipelines
This large-diameter pipe, with an external diameter over 406.4 mm, is made from alloy steel and longitudinally welded for high-pressure oil transportation. It falls under HTS 7305.31.60 due to its circular cross-section, welded construction, and alloy steel material exceeding the size threshold. Primarily used in midstream oil and gas infrastructure.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of iron or non-alloy steel
Non-alloy steel versions shift to 7305.11, as alloy content determines the subheading within welded large-diameter pipes.
If seamless construction
Seamless pipes, even large-diameter alloy steel, classify under 7304 as they lack welds, differentiating from welded tubes in 7305.
If specifically designed as gas transmission piping for stationary engines
End-use as pressure piping for gas turbines moves it to Chapter 84 parts, based on functional specificity over general tube classification.

Import Tips & Compliance
• Verify alloy steel composition meets ASTM A335 or equivalent standards with mill test certificates to avoid reclassification
• Provide detailed welding process documentation (longitudinal submerged arc) as proof for HTS 7305.31.60 eligibility
