Incoloy 825 Seamless Cold-Drawn Tube
A seamless cold-drawn tube made from Incoloy 825, a high-nickel alloy steel (Ni 38-46%, Cr 19.5-23.5%), with circular cross-section and external diameter under 19 mm. Classified under HTS 7304.41.30.05 due to its seamless construction, cold-drawn process, stainless steel composition, and high-nickel content for corrosion resistance in chemical processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If welded instead of seamless
Welded tubes of high-nickel stainless steel fall under Chapter 73 heading 7306 for welded pipes, not seamless under 7304.
If supplied in coil form, not cut lengths
Cold-rolled stainless bars/rods in coils over tubes; tubes are typically straight lengths, coils classified as bars under 7222.
If external diameter 19 mm or greater
Size threshold changes subheading within 7304.41; larger OD tubes go to other cold-formed stainless categories.

Import Tips & Compliance
• Provide mill test certificates confirming high-nickel alloy composition (e.g
• >30% Ni) and seamless cold-drawn production to avoid reclassification
• Measure and document external diameter (<19 mm) precisely, as exceeding this triggers different subheadings
