HS Code 8109.29 – Zirconium; unwrought, powders, containing not less than 1 part hafnium to 500 parts zirconium by weight
HS code 8109.29 is the 6-digit subheading for zirconium, unwrought, powders, containing not less than 1 part hafnium to 500 parts zirconium by weight. It is used for industrial-grade zirconium powder, zirconium alloy powders, zirconium sponge (high hafnium) and zirconium ingots (high hafnium).
What HS 8109.29 covers
This HS code covers unwrought zirconium in powder form where the hafnium content is higher, specifically not less than 1 part hafnium to 500 parts zirconium. Unlike its low-hafnium counterpart, this material is generally used in non-nuclear applications where hafnium's neutron absorption properties are not a concern or are even beneficial. Key industries include specialty alloys, ceramics, refractories, and chemical processing, where zirconium's corrosion resistance, high melting point, and chemical stability are valued. Importers and exporters are typically countries with advanced manufacturing capabilities in these sectors. Understanding the specific alloy compositions and intended industrial applications is crucial for accurate classification and trade, as the presence of hafnium significantly differentiates its end-use from nuclear-grade zirconium.

Codes often confused with 8109.29
Common mistake. This code is differentiated from 810921 by its higher hafnium content, and from 810999 by being in unwrought powder form rather than other wrought or semi-finished forms.
Top exporters and importers of HS code 810929, 2025
In 2025, the largest exporter of HS code 810929 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).

What are common misclassifications for HS code 810929?
This code is differentiated from 810921 by its higher hafnium content, and from 810999 by being in unwrought powder form rather than other wrought or semi-finished forms.
Which countries are the top exporters of goods under HS code 810929?
In 2025, the top exporters of HS code 810929 in UN Comtrade data were Germany ($22M, 66% of world exports), China ($4.7M) and Sweden ($2.9M). World exports came to about $33M, 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.
