HS Code 76.08 – Aluminium; tubes and pipes

HS code 7608 is a 4-digit heading in the Harmonized System that covers: Aluminium; tubes and pipes. HS Code 7608 pertains to aluminium tubes and pipes, encompassing both seamless and welded varieties. This heading covers a wide array of hollow cylindrical products made from aluminium or aluminium alloys, designed for structural applications, fluid conveyance, or as components in various manufactured goods. The scope includes tubes and pipes of all dimensions and cross-sections, provided they maintain a hollow form. Key sub-categories often distinguish between seamless (produced by extrusion or drawing) and welded (formed from strip and welded along the seam) tubes, as well as by specific alloy types which dictate properties like strength, corrosion resistance, and weldability. This classification is vital for trade compliance because the form factor (hollow vs. solid) is the primary distinction from products like bars, rods, and profiles (7604). Misclassification can lead to incorrect duties, delays, and penalties. Aluminium tubes and pipes are historically significant due to their lightweight nature, excellent strength-to-weight ratio, and corrosion resistance, making them ideal substitutes for heavier steel in applications ranging from aerospace to construction. Within Chapter 76, this heading represents a semi-finished product that undergoes further processing or assembly into final goods, positioning it as a crucial intermediate in the aluminium value chain, building upon the raw material stage (7601) and preceding more complex structures (7610).

Seamless aluminium pipes, welded aluminium tubes, extruded aluminium tubing for architectural frames, drawn aluminium pipes for irrigation, aerospace-grade aluminium tubing, automotive exhaust tubing, bicycle frame tubes, refrigeration coil tubing, heat exchanger tubes, scaffolding tubes, tent pole tubing, flag pole tubing, electrical conduit tubing, hydraulic system tubing, pneumatic system tubing, furniture frame tubes, marine application pipes, decorative aluminium pipes, industrial fluid transfer pipes, structural support tubes, medical equipment tubing, antenna mast tubing, solar panel mounting tubes, playground equipment tubes, curtain rod tubes

A common mistake is confusing aluminium tubes and pipes with 'Aluminium bars, rods, and profiles' under HS 7604. The crucial distinction is that tubes and pipes are hollow, while bars and rods are solid. Profiles can be hollow but typically have more complex, non-circular cross-sections designed for specific structural or architectural purposes, though some simple hollow profiles might overlap. Another error is classifying tube or pipe fittings (e.g., elbows, couplings) under 7608, when they correctly belong to 7609. Lastly, if the tubes are already assembled into a recognizable structure, they might fall under 7610 (Aluminium structures and parts), rather than as individual tubes.

In 2025, the top exporters of HS code 7608 in UN Comtrade data were China ($496M, 20% of world exports), Germany ($301M) and the United States ($298M). World exports came to about $2.5B, 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.

In 2025, the top importers of HS code 7608 in UN Comtrade data were Mexico ($327M, 12% of world imports), Germany ($259M) and the United States ($149M). World imports came to about $2.7B, 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.

HS code 7608 is a 4-digit heading under Chapter 76 of the Harmonized System. The first 2 digits (76) identify the chapter, and digits 3-4 (08) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
