## What thulium is used for

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 supply and demand factors

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 price history

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.

## Where thulium is produced

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.

## Why thulium is a critical mineral

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.

## How the thulium benchmark price is calculated

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.

### Converting the price

- Thulium oxide contains about 88% thulium
