HS Code 7605.21 – Aluminium; alloys, wire, maximum cross-sectional dimension exceeding 7mm
HS code 7605.21 is the 6-digit subheading for aluminium, alloys, wire, maximum cross-sectional dimension exceeding 7mm. It is used for aluminium alloy welding wire (large diameter), aluminium alloy structural wire, aluminium alloy rivet stock, aluminium alloy conductor wire (high strength) and aluminium alloy rod for fasteners.
What HS 7605.21 covers
This HS code covers aluminium alloy wire with a maximum cross-sectional dimension exceeding 7mm. These larger diameter alloy wires are highly sought after in international trade for applications demanding a combination of high strength, specific mechanical properties, and the inherent lightweight and corrosion resistance of aluminium. They are crucial in sectors where structural integrity and performance under stress are critical. Major importers include countries with robust aerospace, automotive, and heavy engineering industries, such as the United States, France, and Germany, which use these wires for structural components, fasteners, and specialized cables. Exporters are typically nations with advanced metallurgical capabilities and access to various alloying elements, alongside primary aluminium production, like China, Canada, and Russia. Key trade factors include the specific alloy composition (e.g., 5xxx, 6xxx, 7xxx series), temper, and surface quality, which directly impact the wire's suitability for high-performance applications.

Codes often confused with 7605.21
Common mistake. This code can be confused with 760511 (unalloyed wire exceeding 7mm) if the alloy content is overlooked, and with 760529 (alloyed wire 7mm or less) due to the size distinction.
Top exporters and importers of HS code 760521, 2025
In 2025, the largest exporter of HS code 760521 in UN Comtrade data was the Netherlands, with 21% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Bahrain did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 37% of its exports here ($50M, CEPII BACI), so it may also belong among the top exporters.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
