Product classification
HS code for Nickel alloy tube: 7507.12
Nickel, tubes and pipes, of nickel alloys.
Classification of nickel alloy tube under HS 7507.12
Nickel alloy tubes and pipes are classified under HS code 7507.12 according to the General Rules of Interpretation (GRI) 1 and 6. This classification is governed by the legal notes of Chapter 75, which covers nickel and articles thereof. Specifically, Heading 75.07 encompasses tubes, pipes, and tube or pipe fittings. To qualify for subheading 7507.12, the product must meet the definition of a tube or pipe as outlined in Chapter Note 1(e), which specifies hollow products, coiled or not, which have a uniform cross-section with only one enclosed void along their whole length in the shape of circles, ovals, rectangles, squares, equilateral triangles, or regular convex polygons. Furthermore, the material must meet the definition of a nickel alloy provided in Subheading Note 1(b), where nickel predominates by weight over each of the other elements, and the content of at least one other element is greater than the limits specified in the table (e.g., iron over 0.5% or copper over 0.8%). These tubes are typically manufactured through extrusion or drawing processes and are valued for their corrosion resistance in extreme environments.

Codes often confused with 7507.12
Common mistake. Nickel alloy tubes are frequently confused with pure nickel tubes, which are classified under HS code 7507.11. The distinction depends entirely on the chemical composition; if the nickel content is 99% or higher by weight and no other element exceeds the limits in Subheading Note 1(a), it is not an alloy. Additionally, tube fittings of nickel alloys are classified under 7507.20, not 7507.12. Importers also occasionally misclassify these under Chapter 73 (7304 or 7306) if they mistake the alloy for a high-grade stainless steel, but the nickel content must be the predominant metal by weight to remain in Chapter 75.
Top exporters and importers of HS 750712 (the code used for nickel alloy tube), 2025
In 2025, the largest exporter of HS 750712 (the code used for nickel alloy tube) in UN Comtrade data was the United States, with 15% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
