Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If external diameter ≤406.4 mm
Smaller diameter welded stainless tubes fall under heading 7306 for other tubes/pipes.
If seamless construction
Seamless stainless steel pipes are classified in 7304, regardless of diameter.
If made of non-alloy steel
Non-stainless alloy steel versions use different subheading in 7305.11.

Import Tips & Compliance
• Verify stainless steel grade (e.g
• 304 or 316) certification to confirm alloy steel status and avoid reclassification
• Provide mill test reports (MTRs) documenting chemical composition, weld integrity, and hydrostatic test results for customs clearance
• Measure external diameter precisely; if ≤406.4 mm, it shifts to 7306, causing duty miscalculation
