Product classification

HS code for Brass tube: 7411.21

Copper, tubes and pipes, of copper-zinc base alloys (brass).

Classification of brass tube under HS 7411.21

HS code 741121 specifically classifies tubes and pipes manufactured from copper-zinc base alloys, commonly known as brass. This classification is determined by two primary factors: the material composition, which must be a brass alloy, and the form factor, which must be a tube or pipe. Brass tubes are widely utilized across various industries due to their advantageous properties, including good corrosion resistance, excellent workability, and often an appealing aesthetic. Common applications span from intricate plumbing systems and efficient heat exchangers to decorative architectural elements and components for musical instruments. The presence of zinc as a primary alloying element with copper is the crucial factor for distinguishing brass products under this code from those made of pure copper or other copper alloys.

Codes often confused with 7411.21

Common mistake. Misclassification frequently occurs with other copper and copper alloy products. HS code 741111 covers tubes and pipes made of refined copper, which lack the specific zinc content characteristic of brass. Confusion also arises with HS code 741129, which classifies tubes and pipes of other copper alloys (e.g., bronze, cupro-nickel, or aluminum bronze) but explicitly excludes copper-zinc base alloys. Furthermore, brass bars, rods, and profiles, classified under HS code 740721, are distinct due to their solid form factor rather than the hollow, tubular structure defined by 741121. Careful attention to both material composition and physical form is essential for accurate classification.

Top exporters and importers of HS 741121 (the code used for brass tube), 2025

In 2025, the largest exporter of HS 741121 (the code used for brass tube) in UN Comtrade data was China, with 21% of world exports; the largest importer in UN Comtrade data was the United States, 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 brass tube

What is the HS code for Brass tube?

The HS code for Brass tube is 741121 (Copper; tubes and pipes, of copper-zinc base alloys (brass)). The HS code for brass tubes and pipes is 741121, specifically for those made of copper-zinc base alloys. This code applies to both seamless and welded varieties, regardless of their cross-sectional shape.

How do I classify Brass tube for customs?

Brass tube is classified under HS code 741121 — Copper; tubes and pipes, of copper-zinc base alloys (brass). This is a 6-digit subheading level code.

How is brass tube differentiated from other copper tubes?

Brass tubes are differentiated from other copper tubes primarily by their specific alloy composition. HS 741121 is reserved for tubes and pipes made from copper-zinc base alloys (brass), whereas other codes cover tubes of refined copper (e.g., 741111) or other copper alloys (e.g., 741129). The presence and proportion of zinc are key identifiers.

Which countries are the top exporters of brass tube (HS 741121)?

In 2025, the top exporters of HS 741121 (the code used for brass tube) in UN Comtrade data were China ($114M, 21% of world exports), Germany ($93M) and Italy ($63M). World exports came to about $546M, 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.

Which countries are the top importers of brass tube (HS 741121)?
