Applications

ApplicationRoleSignificance
Thulium fiber lasers (TFL)1.94 µm emission for soft-tissue ablation; BPH/prostate surgery (ThuLEP, ThuVARP)Fastest-growing surgical laser modality; preferred over Ho:YAG for smaller fibre diameter and superior vapourisation efficiency [8][9]
Tm:YAG and Tm:YSGG lasers2.01 µm eye-safe IR; military rangefinding, laser designators, covert illuminationNATO and allied defence procurement; eye-safe wavelength avoids retinal hazard under field conditions [10]
Thulium-doped fibre amplifiers (TDFAs)Optical gain in the S-band (1,460 to 1,530 nm); extends usable telecom spectrum beyond C- and L-bandCritical enabler for future wideband wavelength-division multiplexing; no established substitute at this wavelength [11]
Thulium-170 portable X-ray sourcesβ−/γ emitter (84 keV); industrial radiography, field weld inspection, portable medical imagingReactor-produced; requires stable 169Tm metal as neutron-activation target; thulium’s monoisotopic nature ensures clean activation products [12]
Nuclear medicine & researchTm-170 intravitreal injections (ocular oncology); Tm-167 cardiac imaging; physics research targetsNiche but clinically active; demand underpins need for high-purity (≥4N) Tm metal with certified isotopic composition [12]

Market & Supply

Global Tm₂O₃ output ~200 to 300 t/y (estimated) [13]
China refined supply share >99% [13][14]
Illegal-mining share of CN output 80.7% (2011 to 2020 cumulative) [15]
Oxide FOB, direct sellers ~$180/kg Tm₂O₃ (25 kg MOQ, Mar 2026) [16]
3N metal, Western retail (1 kg) ~$1,796/kg [17]
4N metal, Western retail (5 g) ~$54,200/kg [18]
4N premium over 3N metal ~30×, driven by vacuum sublimation step [18]
Retail-to-bulk premium ~10× (metal retail vs. oxide benchmark) [17][16]

Non-Chinese supply pipeline

ProjectLocationProductStatus
Lynas Rare EarthsKuantan, MalaysiaHeavy REE separation (Tm planned)First non-CN HREE producer, May 2025; Tm quantities minimal [19]
Iluka Resources (Eneabba)Western AustraliaMixed HREE incl. TmRefinery commissioning expected 2026; Tm not yet listed separately [19]
Energy Fuels (White Mesa)Utah, USRE concentrate from monaziteHREE separation pre-commercial; Tm not yet isolated [20]

No project currently produces commercial separated thulium outside China. Thulium’s very low natural abundance (~0.52 ppm crustal average) places it among the last heavy REEs to be extracted at any new facility.

Important Notes

November 2026 deadline China’s October 2025 thulium export controls (No. 57/2025) are suspended until 10 November 2026. The regulation is legally intact and can reactivate without new legislation [6]. If reinstated, it covers all forms of metallic thulium, alloys, sputtering targets, crystal materials, and all Tm oxides and compounds. Unlike the April 2025 restrictions, no Western supply chain has yet been rebuilt to account for this risk.
4N purity ceiling: the vacuum sublimation step Industrial vacuum metallothermic reduction of Tm₂O₃ yields metal at 99.5 to 99.9% (2N5 to 3N). Achieving 4N (99.99%) requires a separate vacuum sublimation purification step, made possible by thulium’s uniquely low boiling point among lanthanides (1,950 °C, compared to >3,000 °C for most others). The step is energy-intensive, low-yield, and performed by only a handful of specialised producers worldwide. The result is a ~30× price premium for 4N over bulk 3N metal, and a hard practical ceiling on available purity for volume buyers [18][29].
Supply fragility: illegal mining dominance A 2024 study (Zhang et al., Journal of Industrial Ecology) estimated that 80.7% of China’s cumulative thulium production from 2011 to 2020 originated from illegal mining operations [15]. This structural dependence on informal supply chains means the traceability and quota requirements introduced under the 2024 Rare Earth Management Regulations may be difficult to enforce, and that rigorous application could cause significant supply disruption without any change to export control status.
TFL laser demand: a rapidly growing structural driver Thulium fiber lasers (1.94 µm) have rapidly displaced Ho:YAG as the preferred modality for endoscopic urological surgery in leading centres, driven by smaller operating fibre diameter, superior soft-tissue vapourisation efficiency, and compatibility with single-use flexible scopes. This shift is recent (post-2020) and represents a structurally new demand vector beyond the traditional Tm-170 X-ray source application [8][9]. Sustained clinical adoption could tighten the small global supply of high-purity thulium metal faster than supply projections anticipate.
