Product classification
HS code for Nickel tube fittings: 7507.20
Nickel, tube and pipe fittings.
Classification of nickel tube fittings under HS 7507.20
Nickel tube fittings are classified under HS code 7507.20. This classification is appropriate for products where nickel is the predominant metal by weight, placing them in Chapter 75. Heading 7507 covers nickel tubes, pipes, and their associated fittings. While subheadings 7507.11 and 7507.12 are reserved for the tubes and pipes themselves, 7507.20 is the specific code for tube or pipe fittings, such as couplings, elbows, and sleeves. These components are essential for changing the direction, diameter, or termination of a piping system. The classification applies to both pure nickel fittings and nickel alloy fittings (such as Monel or Inconel), provided the nickel content is greater than any other single element.

Codes often confused with 7507.20
Common mistake. Nickel tube fittings are frequently misclassified under 7307, which covers iron or steel fittings, especially when the alloy contains iron. However, if the nickel content is higher than the iron content, Chapter 75 takes precedence. They may also be confused with 7412.20 (copper alloy fittings) if the alloy is actually nickel silver or cupro-nickel, which are copper-based.

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).
