Product classification
HS code for Copper alloy tube: 7411.29
Copper, tubes and pipes, of copper alloys (other than copper-zinc, copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel-silver)).
Classification of copper alloy tube under HS 7411.29
HS code 7411.29 is the designated classification for tubes and pipes made from copper alloys that do not fall into the primary categories of brass, cupro-nickel, or nickel-silver. In the nomenclature of the Harmonized System, tubes and pipes are defined as hollow products, whether in coils or not, which have a uniform cross-section with only one enclosed void. This cross-section can be circular, oval, rectangular, or even equilateral polygonal, provided the wall thickness remains uniform throughout the entire length of the product. The subheading 7411.29 acts as a "basket" category for specialized copper alloys. This includes materials such as aluminum bronze, beryllium copper, and certain types of silicon bronze. These tubes are essential in high-performance industrial applications, such as heat exchangers, condensers, and hydraulic systems, where the specific properties of the alloy—such as high strength or resistance to chemical attack—are required. The manufacturing of these tubes typically involves extrusion or drawing processes. In some cases, they may be produced by welding, but they must still meet the criteria of having a uniform wall thickness. It is vital for trade compliance professionals to distinguish between these semi-finished tubes and finished articles or tube fittings. If a tube has been further worked into a specific part, it may require a different classification.

Codes often confused with 7411.29
Common mistake. Common misclassifications occur with 7411.10 (refined copper tubes) and 7411.21 (copper-zinc alloy tubes). Additionally, importers often confuse tubes with tube fittings; fittings such as elbows, couplings, and sleeves must be classified under heading 7412 rather than 7411.
Top exporters and importers of HS 741129 (the code used for copper alloy tube), 2025
In 2025, the largest exporter of HS 741129 (the code used for copper alloy tube) in UN Comtrade data was Germany, with 24% of world exports; the largest importer in UN Comtrade data was Germany, with 17% 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 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).

Questions about copper alloy tube
What is the HS code for Copper alloy tube?
The HS code for Copper alloy tube is 741129 (Copper; tubes and pipes, of copper alloys (other than copper-zinc, copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel-silver))). The HS code for tubes and pipes made of copper alloys (excluding brass, cupro-nickel, and nickel-silver) is 7411.29.
How do I classify Copper alloy tube for customs?
Copper alloy tube is classified under HS code 741129 — Copper; tubes and pipes, of copper alloys (other than copper-zinc, copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel-silver)). This is a 6-digit subheading level code.
Can welded tubes be classified under 7411.29?
Yes, provided the welded tube has a uniform wall thickness and a consistent cross-section, it is classified under 7411.29 regardless of the manufacturing method.
Which countries are the top exporters of copper alloy tube (HS 741129)?
In 2025, the top exporters of HS 741129 (the code used for copper alloy tube) in UN Comtrade data were Germany ($116M, 24% of world exports), Austria ($76M) and Thailand ($39M). World exports came to about $477M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
