That makes them the magnet of choice in **defence and aerospace**: guided munitions, aircraft actuators, satellites and high-performance sensors. Samarium-153 is also used in medicine to ease the pain of bone cancer. ### Other uses - Neutron absorbers in nuclear reactors - Infrared-absorbing glass - Catalysts in chemical production - Lasers and optical materials ## Samarium supply and demand factors Samarium is a by-product of rare earth separation, mostly in China, and its market is small. Demand is concentrated in samarium-cobalt magnets for defence and aerospace, where reliability at high temperatures matters more than cost. China's export controls on samarium have raised concerns about Western defence supply chains. ### What moves the price - Chinese export controls - Defence and aerospace procurement - Cobalt prices, which affect samarium-cobalt magnet costs - New separation capacity outside China ## Samarium price history Samarium was a low-priced by-product for years, with surplus supply from rare earth separation. China's 2025 export controls on samarium have raised its strategic profile, given its role in defence magnets. As of October 2026, the Stockatomics benchmark price is $3.27 per kg contained. ## Where samarium is produced Samarium is separated from rare earth ores, mostly in **China**, as part of the medium rare earth stream. Small amounts are separated elsewhere, and new projects in the US, Europe and Australia aim to add supply outside China. ## Why samarium is a critical mineral Samarium is on the **US critical minerals list**, and the light rare earths are on the **EU critical raw materials list**. High-temperature magnets in defence systems depend on it, separated supply is concentrated in China, and China has placed it under export control. ## How the samarium benchmark price is calculated Stockatomics publishes a US benchmark price for samarium in US dollars per kg contained, reading as of October 2026. The price is quoted per kg of oxide, not for a finished magnet. US trade in samarium is thin, so its price moves less often than those of the higher-volume minerals. ### Converting the price - Samarium oxide contains about 86% samarium ## FAQ ### What is the price of samarium per kg today? The Stockatomics US benchmark price of samarium is $3.27 per kg contained as of October 2026. Stockatomics updates it every month. ### What is samarium used for? Mainly samarium-cobalt magnets, which keep their strength at very high temperatures, for defence and aerospace systems. ### Why is samarium strategic? Guided munitions, aircraft and satellites depend on samarium-cobalt magnets, and separated samarium supply is concentrated in China. ### Is samarium subject to export controls? Yes. China placed samarium under export control in 2025. ### How is the samarium benchmark price calculated? The Stockatomics benchmark for samarium is a monthly US price in US dollars per kg contained, published every month and current as of October 2026. ## Related commodities - [Lithium price per kg](https://www.stockatomics.com/commodities/lithium-price-us): $89.62 per kg contained - [Copper price per kg](https://www.stockatomics.com/commodities/copper-price-us): $13.92 per kg contained - [Cobalt price per kg](https://www.stockatomics.com/commodities/cobalt-price-us): $56.81 per kg contained - [Nickel price per kg](https://www.stockatomics.com/commodities/nickel-price-us): $17.24 per kg contained - [Graphite price per kg](https://www.stockatomics.com/commodities/graphite-price-us): $1.17 per kg graphite - [Gallium price per kg](https://www.stockatomics.com/commodities/gallium-price-us): $1,530 per kg contained ## Sources - U.S. trade data: the monthly samarium price. - U.S. Geological Survey (USGS): the US critical minerals list. - Company filings: the listed companies and their roles.
