Alloy 625 Cold-Drawn Seamless Tube
Alloy 625 (Inconel 625) is a high-nickel alloy steel (~58% nickel) formed into seamless cold-drawn tubes for aerospace and nuclear applications. These precision cold-reduced pipes have circular cross-sections and are classified under HTS 7304.51.50.05 due to their high-nickel content and seamless, cold-formed nature. Excellent for high-temperature strength.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If of other alloy steel not qualifying as high-nickel
Lower nickel alloys fall under general 'other alloy steel' in 7304.39, not specific high-nickel subheading.
If for use in gas turbines as finished components
End-use in turbojets classifies as machinery parts under 8411, not base tubes.
If other cold-formed but not further specified
Slight variations in processing may place under broader cold-formed alloy steel headings.

Import Tips & Compliance
• Include heat number traceability and PMI test results for nickel verification during customs inspection
• Avoid bundling with fittings; ship as individual tubes to prevent set classification issues
