HS Code for Copper alloy tube

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.

Products Included

• Aluminum bronze tubes
• Beryllium copper pipes
• Silicon bronze tubing
• High-strength copper alloy conduits
• Specialized alloy heat exchanger tubes

Common Misclassification

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.

FAQ

What is the HS code for Copper alloy tube?

The HS code for tubes and pipes made of copper alloys (excluding brass, cupro-nickel, and nickel-silver) is 7411.29.

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.
