HS Code 2844.43 – Radioactive elements, isotopes and compounds; other alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds
HS code 2844.43 is the 6-digit subheading for radioactive elements, isotopes and compounds, other alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds. It is used for cobalt-60 sources, iridium-192 sources, strontium-90 sources, americium-241 sources and carbon-14 compounds.
What HS 2844.43 covers
This category encompasses radioactive elements, isotopes, and their compounds, alloys, dispersions, or mixtures that are not specifically listed under 284442 but are still defined radioactive materials. These substances find extensive use in industrial applications, medical diagnostics, and various research fields. Examples include Cobalt-60 for sterilization and radiography, Iridium-192 for industrial inspection, and Americium-241 for smoke detectors. Trade involves specialized chemical companies, nuclear facilities, and research laboratories globally. Key considerations include the strict international regulations governing their production, transport, and use, focusing on safety, security, and non-proliferation. The market is influenced by demand from healthcare, energy, and industrial sectors requiring precise isotopic applications.

Codes often confused with 2844.43
Common mistake. This code covers 'other' defined radioactive elements not in 284442. It is often confused with 284442 if the isotope is specifically listed there, or with 284444 for truly unspecified radioactive materials or residues.
Top exporters and importers of HS code 284443, 2025
In 2025, the largest exporter of HS code 284443 in UN Comtrade data was Canada, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 26% 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 HS 2844.43
What is HS code 284443?
HS code 284443 is a 6-digit subheading in the Harmonized System that covers: Radioactive elements, isotopes and compounds; other alloys, dispersions (including cermets), ceramic products and mixtures containing these elements, isotopes or compounds. This category encompasses radioactive elements, isotopes, and their compounds, alloys, dispersions, or mixtures that are not specifically listed under 284442 but are still defined radioactive materials. These substances find extensive use in industrial applications, medical diagnostics, and various research fields. Examples include Cobalt-60 for sterilization and radiography, Iridium-192 for industrial inspection, and Americium-241 for smoke detectors. Trade involves specialized chemical companies, nuclear facilities, and research laboratories globally. Key considerations include the strict international regulations governing their production, transport, and use, focusing on safety, security, and non-proliferation. The market is influenced by demand from healthcare, energy, and industrial sectors requiring precise isotopic applications.
What products fall under HS code 284443?
Cobalt-60 sources, Iridium-192 sources, Strontium-90 sources, Americium-241 sources, Carbon-14 compounds, Tritium gas, Technetium-99m generators.
What are common misclassifications for HS code 284443?
This code covers 'other' defined radioactive elements not in 284442. It is often confused with 284442 if the isotope is specifically listed there, or with 284444 for truly unspecified radioactive materials or residues.
Which countries are the top exporters of goods under HS code 284443?
In 2025, the top exporters of HS code 284443 in UN Comtrade data were Canada ($490M, 20% of world exports), the Netherlands ($374M) and Germany ($368M). World exports came to about $2.4B, 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.
