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 of iron or non-alloy steel with protective coating
Base material (non-stainless) moves it to different stainless vs non-stainless line pipe subheadings.
If imported as part of oil/gas pipeline machinery
When assembled into complete pipeline systems or equipment, classified by function.
If longitudinally welded rather than seamless
Welded construction excludes from seamless tube/pipes Chapter 73 heading 7304.

Import Tips & Compliance
• Include hydrostatic test certificates showing pressure ratings suitable for pipeline service
• Labeling must specify 'line pipe' end use; generic 'tube' descriptions trigger CBP reclassification
• For large diameters (>10 inches), confirm no weld seams via non-destructive testing reports
