HS Code 76.09 – Aluminium; tube or pipe fittings (e.g. couplings, elbows, sleeves)
What HS 76.09 covers
HS Code 7609 specifically covers aluminium tube or pipe fittings, which are essential components used to connect, change direction, or terminate sections of aluminium tubes and pipes. This heading includes a wide variety of fittings such as couplings, elbows, sleeves, flanges, reducers, tees, caps, and unions. The scope is defined by their material (aluminium) and their function as connecting or modifying elements for tubing and piping systems. These fittings are crucial in establishing leak-proof and structurally sound connections in diverse applications, from plumbing and HVAC to industrial process piping and structural frameworks. Key sub-categories might differentiate fittings by their connection type (e.g., threaded, welded, compression, grooved) or specific design for particular pressures or environments. This classification is vital for trade compliance as it strictly delineates these connecting pieces from the tubes and pipes themselves (7608) or from articles with a more complex mechanical function (like valves under 8481). Historically, the development of robust and lightweight aluminium fittings has paralleled the increased use of aluminium piping in industries where weight, corrosion resistance, and ease of installation are paramount, such as marine, aerospace, and chemical processing. Within Chapter 76, heading 7609 serves as a specialized category for essential accessories that complete aluminium piping systems, reflecting the material's versatility beyond simple linear forms.

An Italian plumbing wholesaler imports a container of various aluminium pipe elbows and couplings from China for distribution to residential and commercial HVAC system installers. A US industrial equipment manufacturer sources specialized aluminium flanges from Germany for its high-pressure fluid transfer systems in chemical processing plants. A South Korean shipyard imports large diameter aluminium reducers and tees from Japan, used in constructing the intricate piping systems for marine vessels. A Canadian construction firm procures aluminium structural pipe fittings for assembling lightweight scaffolding and temporary structures on job sites from Mexico. A European food processing company purchases sanitary aluminium fittings from the USA for its clean-in-place (CIP) systems.

Codes often confused with 76.09
Common mistake. A common misclassification error for aluminium pipe fittings is confusing them with the 'Aluminium tubes and pipes' themselves, which fall under HS 7608. Fittings are designed to *connect* or *modify* the flow in tubes/pipes, not to be the primary conduit. Another mistake is classifying items with a functional control mechanism, such as a valve or tap, under 7609; these would typically fall under HS 8481 (Taps, cocks, valves and similar appliances). Finally, small, general-purpose aluminium articles that are not specifically fittings might be incorrectly placed here instead of in 7616 (Other articles of aluminium). The key is the explicit function of joining or altering a piping system.
Top exporters and importers of HS code 7609, 2025
In 2025, the largest exporter of HS code 7609 in UN Comtrade data was the United States, with 18% of world exports; the largest importer in UN Comtrade data was Mexico, with 10% 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).
