Product classification
HS code for Zirconium powder: 8109.29
Zirconium, unwrought, powders, containing not less than 1 part hafnium to 500 parts zirconium by weight.
Classification of zirconium powder under HS 8109.29
HS code 810929 is the specific classification for zirconium powders that contain a significant amount of hafnium. The Harmonized System classifies other base metals in Chapter 81, and heading 8109 is dedicated to zirconium and articles thereof. The structure of this heading distinguishes between unwrought forms (including waste and scrap) and wrought forms (like sheets or pipes). Subheading 8109.29 specifically covers unwrought zirconium and powders, provided they meet the hafnium ratio requirement: containing not less than 1 part hafnium to 500 parts zirconium by weight. This is a critical distinction because high-purity zirconium (with very low hafnium content) is used in nuclear reactors due to its low neutron-absorption cross-section. Such nuclear-grade zirconium is classified under 8109.21. The powder form classified under 8109.29 is often used in non-nuclear applications, such as in the manufacture of vacuum tube getters, specialized alloys, or as a component in pyrotechnic mixtures. The classification depends on both the physical form (powder) and the chemical purity (hafnium content).

Codes often confused with 8109.29
Common mistake. This code is frequently confused with 810921, which is reserved for zirconium with a hafnium-to-zirconium ratio of less than 1:500 (nuclear grade). It is also confused with 810931, which covers zirconium waste and scrap. Furthermore, zirconium dioxide (the oxide form) should be classified under 282560 rather than the metal powder code.
Top exporters and importers of HS 810929 (the code used for zirconium powder), 2025
In 2025, the largest exporter of HS 810929 (the code used for zirconium powder) in UN Comtrade data was Germany, with 66% of world exports; the largest importer in UN Comtrade data was Czechia, 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).
