Incoloy 825 Welded Stainless Steel Pipe
Welded circular stainless steel pipe made from high-nickel Incoloy 825 alloy, with wall thickness exceeding 1.65 mm, used in chemical processing for corrosion resistance. Classified under HTS 7306.40.50.05 due to its high-nickel alloy steel composition, welded construction, and specified dimensions. Meets chapter definition for other tubes and pipes of iron or steel.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If wall thickness under 1.65 mm
Thinner-walled high-nickel stainless steel welded pipes shift to 7306.40.10 for walls <1.65 mm.
If seamless instead of welded
High-nickel alloy steel bars and rods, hollow, including seamless pipes, classify under Chapter 72 as semi-finished.
If not high-nickel alloy steel
Other welded stainless steel pipes of circular section with thick walls fall under 7306.50 if lacking high-nickel designation.

Import Tips & Compliance
• Verify alloy composition certification showing high-nickel content (e.g
• >40% Ni) to confirm classification under 7306.40.50.05
• Measure and document wall thickness ≥1.65 mm and circular cross-section to avoid reclassification to thinner wall subheadings
• Obtain mill test reports (MTRs) proving stainless steel and welded construction; common pitfall is missing traceability docs
