Product classification
HS code for Nickel alloy pipe: 7507.12
Nickel, tubes and pipes, of nickel alloys.
Classification of nickel alloy pipe under HS 7507.12
Nickel alloy pipes are classified under HS code 7507.12. This classification is determined by the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1 and 6. Chapter 75 of the Harmonized System covers nickel and articles thereof. Within this chapter, heading 75.07 is dedicated to nickel tubes, pipes, and tube or pipe fittings. The subheading 7507.12 specifically identifies tubes and pipes made from nickel alloys. To qualify as a nickel alloy under Note 1(b) to Chapter 75, the metal must contain nickel by weight that predominates over each of the other elements, provided that the total content of elements other than nickel exceeds 1.5 percent, or the content of at least one other element is greater than the limit specified in the chapter's sub-heading notes. These pipes are typically used in environments requiring high resistance to corrosion and heat, such as chemical processing plants, marine engineering, and oil and gas extraction. The classification remains consistent regardless of the manufacturing process, whether the pipes are seamless or welded, provided they meet the dimensional and metallurgical criteria for nickel alloys. The distinction between unalloyed nickel and nickel alloys is critical for correct classification, as unalloyed pipes fall under 7507.11.

Codes often confused with 7507.12
Common mistake. Nickel alloy pipes are frequently confused with stainless steel pipes classified under headings 73.04, 73.05, or 73.06. The distinction depends on the nickel content; if iron predominates by weight, the product is classified as steel. Additionally, tube or pipe fittings of nickel alloys are classified under 7507.20, not 7507.12. Pure nickel pipes (unalloyed) must be classified under 7507.11.
Top exporters and importers of HS 750712 (the code used for nickel alloy pipe), 2025
In 2025, the largest exporter of HS 750712 (the code used for nickel alloy pipe) 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).
