API 5L Grade X65 Alloy Steel Line Pipe
This is a welded alloy steel pipe conforming to API 5L X65 specifications, designed specifically for high-pressure oil and gas pipelines. It features enhanced strength from alloying elements like chromium and molybdenum, with wall thicknesses typically ranging from 0.25 to 1 inch and diameters up to 48 inches. Classified under 7306.19.51 as 'other' line pipe of alloy steel used for oil or gas pipelines.

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 seamless construction
Seamless alloy steel tubes/pipes fall under heading 7304, distinguished from welded line pipe in 7306 by manufacturing process.
If not specifically for oil/gas pipelines
If used for other applications like structural or mechanical, it shifts to other welded alloy steel pipes outside line pipe provisions.
If longitudinal butt-welded only
Narrower classification for specific electric resistance or furnace butt-welded line pipe, depending on weld method.

Import Tips & Compliance
• Verify API 5L certification and mill test reports (MTRs) to confirm alloy composition and mechanical properties for customs compliance
• Ensure proper marking of outside diameter, wall thickness, and grade on each pipe length to avoid reclassification
