HS Code for Copper alloy pipe

Copper alloy pipes and tubes are classified under HS code 7411.29. This classification is part of Chapter 74, which covers copper and articles thereof. Heading 7411 is specifically dedicated to tubes and pipes. To be classified here, the product must be a hollow semi-finished product, usually in coils or straight lengths, with a uniform wall thickness and a constant cross-section. Subheading 7411.29 is the residual category for pipes made of copper alloys that are not copper-zinc (brass), copper-nickel (cupro-nickel), or copper-nickel-zinc (nickel silver). The classification depends heavily on the chemical analysis of the alloy. If the copper content is the highest by weight and the alloy does not fit the specific definitions of the other subheadings, 7411.29 is the correct designation for these wrought products.

Products Included

• Aluminum bronze pipes
• Silicon bronze tubing
• Beryllium copper hollow bars
• Phosphor bronze tubes
• High-strength copper alloy piping for industrial use
• Seamless copper alloy tubes (non-brass/non-cupro-nickel)

Common Misclassification

The most frequent misclassification occurs with HS code 7411.10, which is for refined (pure) copper pipes. Users also often confuse 7411.29 with 7411.21 (brass) or 7411.22 (cupro-nickel). It is essential to verify the metallurgical composition; for instance, if the zinc content exceeds certain thresholds, it must be classified as brass. Additionally, pipe fittings (elbows, tees, etc.) are not classified here; they belong under HS code 7412.

FAQ

What is the HS code for copper alloy pipe?

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

Does this code include flexible copper hoses?

If the hose is a simple copper alloy tube, it may fall here, but if it is reinforced or fitted with attachments, it might be classified elsewhere as a finished article.
