Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If over 114.3 mm outside diameter
Larger diameter welded stainless tubes classify under 7306.40.50xx regardless of wall thickness.
If imported as machine parts, not bulk tubing
Fabricated into finished machinery components shifts to Chapter 84/85 parts headings.
If seamless construction confirmed
Seamless versions of same alloy go to cold-drawn seamless tubes in 7304.41.

Import Tips & Compliance
• Super-austenitic alloys need detailed UNS designation in entry summary to match statistical notes
• Avoid declaring as 'pipe'—use 'tubing' to stay in precision tube categories
