Import Tips
• 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
