HS code for Aluminum hollow profile: 7604.21
Aluminium, alloys, hollow profiles.
Classification of aluminum hollow profile under HS 7604.21
HS code 760421 specifically covers "Aluminium; alloys, hollow profiles". This classification applies to products made from aluminum or its alloys that possess a consistent cross-section and a hollow interior throughout their length. The designation "hollow profiles" is crucial, differentiating these items from solid profiles (categorized under other subheadings within HS 7604) and from profiles made of non-alloyed aluminum. The presence of alloying elements and the distinct hollow characteristic are the primary criteria for inclusion, reflecting their common use in structural and industrial applications.

Codes often confused with 7604.21
Common mistake. 760410 (Aluminium; unwrought, not alloyed, bars, rods and profiles): This code is for non-alloyed aluminum products. Misclassification occurs if the alloy content is overlooked or if the hollow nature is not considered, as 760410 does not specify hollow profiles. 760429 (Aluminium; alloys, other profiles): This subheading covers other profiles of aluminum alloys that are not hollow. Confusion arises if the internal void is not precisely identified, as 760421 specifically requires a hollow structure. 7608 (Aluminium tubes and pipes): While both are hollow, tubes and pipes are generally designed for conveying fluids or gases. Profiles are typically structural or decorative, with more varied cross-sections. The distinction lies in primary intended use.
Top exporters and importers of HS 760421 (the code used for aluminum hollow profile), 2025
In 2025, the largest exporter of HS 760421 (the code used for aluminum hollow profile) in UN Comtrade data was China, with 22% of world exports; the largest importer in UN Comtrade data was Germany, with 14% 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 aluminum hollow profile
What is the HS code for Aluminum hollow profile?
The HS code for Aluminum hollow profile is 760421 (Aluminium; alloys, hollow profiles). Aluminum hollow profiles are classified under HS code 760421. This code specifically applies to hollow profiles manufactured from aluminum alloys, distinguishing them from solid profiles or those made from non-alloyed aluminum. This classification ensures accurate identification for customs and trade purposes based on material composition and structural form.
How do I classify Aluminum hollow profile for customs?
Aluminum hollow profile is classified under HS code 760421 — Aluminium; alloys, hollow profiles. This is a 6-digit subheading level code.
How are aluminum hollow profiles distinguished from aluminum tubes for HS classification?
Aluminum hollow profiles (HS 760421) are primarily structural or architectural components, often featuring complex or non-standard cross-sections, and are not typically designed for fluid conveyance. Aluminum tubes and pipes (HS 7608), while also hollow, are generally intended for transporting liquids or gases and commonly possess uniform circular, oval, or rectangular cross-sections. The fundamental distinction for HS classification rests on their primary intended function and typical geometric design.
Which countries are the top exporters of aluminum hollow profile (HS 760421)?
In 2025, the top exporters of HS 760421 (the code used for aluminum hollow profile) in UN Comtrade data were China ($1.5B, 22% of world exports), Germany ($897M) and Türkiye ($646M). World exports came to about $6.9B, 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 aluminum hollow profile (HS 760421)?
In 2025, the top importers of HS 760421 (the code used for aluminum hollow profile) in UN Comtrade data were Germany ($864M, 14% of world imports), the United States ($592M) and France ($339M). World imports came to about $6.1B, 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.
Is the HS code for Aluminum hollow profile the same in all countries?
The base HS code 760421 for Aluminum hollow profile is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for aluminum hollow profile in Brazil?
In Brazil, aluminum hollow profile (HS 760421) is classified under NCM 7604.21.00.
