7304.51.50.05/Incoloy 825 Seamless Cold-Drawn Tube/China

Incoloy 825 Seamless Cold-Drawn Tube from China

Incoloy 825 is a high-nickel alloy steel (Ni-Fe-Cr alloy with >38% nickel) used for seamless cold-drawn tubes in corrosive environments like chemical processing. These tubes have a circular cross-section, are cold-rolled for precision, and fall under HTS 7304.51.50.05 due to their high-nickel composition and seamless construction. They are ideal for heat exchangers and piping in harsh industrial settings.

Import Tips

• Verify alloy composition certificate showing >38% nickel to confirm high-nickel alloy steel classification under 7304.51.50.05

• Provide mill test reports (MTRs) proving seamless production and cold-drawing process to avoid reclassification as welded

• Ensure tubes meet ASTM B423 standards; common pitfall is incorrect measurement of wall thickness leading to duty disputes
