Product classification

HS code for Cupronickel tube: 7411.22

Copper, tubes and pipes, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver).

Classification of cupronickel tube under HS 7411.22

Cupronickel tubes and pipes fall under HS code 7411.22. This classification is determined by the material composition and the physical form of the product as defined in Chapter 74 of the Harmonized System. Heading 7411 specifically addresses tubes and pipes of copper. Within this heading, the subheadings are organized by the type of copper or copper alloy used. Subheading 7411.22 is reserved for tubes made of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). To qualify for this code, the product must meet the definition of "tubes and pipes" provided in the Chapter 74 legal notes: they must be hollow products, coiled or not, which have a uniform cross-section with only one enclosed void along their whole length. The wall thickness must also be uniform. These tubes are widely used in heat exchangers, condensers, and marine piping systems due to their ability to withstand high-velocity seawater flow and resist stress corrosion cracking.

Codes often confused with 7411.22

Common mistake. Cupronickel tubes are often misclassified under 7411.10, which is only for refined (unalloyed) copper tubes. They may also be confused with 7412.20, which covers copper alloy tube or pipe fittings (such as couplings or elbows) rather than the tubes themselves. If the product is not hollow or does not have a uniform wall thickness, it may be classified as a profile under 7407.29.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
