Thulium Price per kg (United States)

In the past year the monthly price has moved between $1,840 and $1,840.

Thulium (Tm) is one of the rarest rare earths, used in small volumes for high-value purposes. Thulium fibre lasers are increasingly used in urology and surgery, and thulium-170 serves as the radiation source in portable X-ray devices.

Other uses

• Thulium-doped fibre amplifiers for optical networks
• Research into high-temperature superconductors
• Radiation dosimeters
• Specialty lasers

Thulium is one of the rarest rare earths, produced in tiny amounts from heavy rare earth deposits, mainly in China. Demand is small and specialised, led by medical lasers and portable X-ray devices, so its price follows the heavy rare earth complex and Chinese policy.

What moves the price

• Heavy rare earth output and Chinese export policy
• Medical laser demand
• Separation capacity outside China
• Research demand

Thulium has a thin market, with prices following heavy rare earth supply and Chinese policy rather than open trading.

As of October 2026, the Stockatomics benchmark price is $1,840 per kg contained.

Thulium is produced in tiny amounts from heavy rare earth deposits, mostly the ionic clays of China and Myanmar, and is separated almost entirely in China.

Thulium is on the US critical minerals list, and the heavy rare earths are on the EU critical raw materials list. Medical devices use it, volumes are tiny, and supply sits in China's separation plants.

Stockatomics publishes a US benchmark price for thulium in US dollars per kg contained, reading as of October 2026. The price is quoted per kg of oxide. US trade in thulium is very thin, so its price moves less often than those of the higher-volume minerals.
