HS Code 2844.44 – Radioactive elements, isotopes, compounds n.e.c. in heading no. 2844, alloys, dispersions (including cermets), ceramic products, mixtures containing the elements, isotopes, compounds; radioactive residues
HS code 2844.44 is the 6-digit subheading for radioactive elements, isotopes, compounds n.e.c. in heading no. 2844, alloys, dispersions (including cermets), ceramic products, mixtures containing the elements, isotopes, compounds, radioactive residues. It is used for depleted uranium alloys, thorium compounds, radioactive waste resins, contaminated laboratory equipment and mixed fission products.
What HS 2844.44 covers
This 'not elsewhere specified' (n.e.c.) code serves as a catch-all for radioactive elements, isotopes, compounds, alloys, dispersions, and mixtures that do not fit into the more specific categories of heading 2844, and importantly, it also includes radioactive residues. This diverse category can range from less common radioactive substances used in niche research to various forms of nuclear waste and contaminated materials. Trade is highly specialized, involving nuclear waste management companies, research facilities, and defense contractors. Key considerations include the long-term storage and disposal challenges, environmental protection, and the stringent international regulations for handling and transporting radioactive materials. The market is driven by the necessity of managing nuclear byproducts and supporting specialized scientific endeavors.

Codes often confused with 2844.44
Common mistake. As a residual category, it's often confused with 284442 or 284443 if the material is specifically listed or falls under a more defined 'other' category. The inclusion of 'radioactive residues' is a key differentiator.
Top exporters and importers of HS code 284444, 2025
In 2025, the largest exporter of HS code 284444 in UN Comtrade data was Australia, with 41% of world exports; the largest importer in UN Comtrade data was Canada, with 27% 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).
