Curium is commercially real in 2025, but only as a state-run isotope catalog market. DOE's National Isotope Development Center lists two curium products: Cm-244 sold in milligrams as nitrate solid and Cm-248 sold in micrograms as nitrate or chloride solid. That is the key commercial fact: curium is not traded as bulk metal, oxide, or concentrate, but as tiny radiochemical lots dispensed from the U.S. isotope-production complex.

The supply chain is entirely nuclear-facility based. Cm-244 is generated by successive neutron captures and beta decays from plutonium-242, while Cm-248 is recovered from the decay of californium-252. ORNL's isotope program describes curium-248 as part of its actinide research inventory for super-heavy-element discovery and related target work, and DOE product sheets show both curium isotopes as stock items requiring nuclear-material transfer controls. Public primary sources do not disclose annual output, prices, or global producer shares, so the atlas record focuses on trade form, feedstock route, and end-use function rather than fabricated tonnage.
