HS Code 2844.41 – Radioactive elements; tritium and its compounds; alloys, dispersions (including cermets), ceramic products and mixtures containing tritium or its compounds
HS code 2844.41 is the 6-digit subheading for radioactive elements, tritium and its compounds, alloys, dispersions (including cermets), ceramic products and mixtures containing tritium or its compounds. It is used for tritium gas, tritiated water, tritium light sources, tritium targets and tritium-containing phosphors.
What HS 2844.41 covers
This specific HS code focuses on tritium, a radioactive isotope of hydrogen, and its compounds, alloys, dispersions (including cermets), ceramic products, and mixtures. Tritium is crucial for various high-tech applications, including self-powered lighting (tritium illumination in watches and exit signs), nuclear fusion research, and as a tracer in scientific studies. It's also a component in some nuclear weapons. Due to its radioactivity and strategic importance, trade in tritium is highly regulated, requiring specialized handling, storage, and transport. Importers and exporters are typically research institutions, specialized manufacturers, and defense-related entities. Strict international and national regulations govern its movement to prevent misuse and ensure safety, making it a tightly controlled commodity.

Codes often confused with 2844.41
Common mistake. This code is specifically for tritium; other radioactive elements (e.g., cobalt-60, carbon-14) would fall under 284440 (if not tritium) or 284442-284443 for specific isotopes.
Top exporters and importers of HS code 284441, 2025
In 2025, the largest exporter of HS code 284441 in UN Comtrade data was the Netherlands, with 28% of world exports; the largest importer in UN Comtrade data was Spain, with 29% 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 284441?
This code is specifically for tritium; other radioactive elements (e.g., cobalt-60, carbon-14) would fall under 284440 (if not tritium) or 284442-284443 for specific isotopes.
Which countries are the top exporters of goods under HS code 284441?
In 2025, the top exporters of HS code 284441 in UN Comtrade data were the Netherlands ($14M, 28% of world exports), Italy ($11M) and the United States ($8.8M). World exports came to about $49M, 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 goods under HS code 284441?
