Thailand rare earth output reached an estimated 4,800 tonnes of rare earth oxide (REO) equivalent in 2025, the fifth-largest national total globally, according to the US Geological Survey’s Mineral Commodity Summaries published in February 2026. That places Thailand behind China (270,000t), the United States (51,000t), Australia (29,000t) and Myanmar (22,000t). The USGS also revised its 2024 estimate for Thailand down to 2,100 tonnes as part of a broader recalculation affecting several producing countries, replacing earlier trade-derived figures that had put the country closer to 13,000 tonnes for that year. Thailand’s reserve base is not currently listed in the USGS reserves table, a gap in the 2026 edition rather than a confirmed zero.
Thailand Rare Earth Position: Production and Reserves
Thailand has no commercial rare earth mining. These figures reflect beneficiation activity rather than ore extraction: domestic firms including Sakorn Minerals in Prachuap Khiri Khan and Ratanarungsiwat in Pang Nga import raw ore and separate the rare earth-bearing minerals from host rock before export, mostly to China for refining. This puts Thailand in a different tier of the region’s supply chain to neighbours such as Vietnam, whose reserve base is far larger but whose mine output has collapsed since a 2023 corruption crackdown.
Upstream: Beneficiation Without Domestic Mining
Thailand’s 2024 trade data show the scale of this pass-through role. The country imported USD 64.4 million of rare earth compounds (HS2846), making it the seventh-largest importer globally, with roughly 80% of that volume sourced from Malaysia. On the export side, Thailand shipped USD 65.9 million of rare earth metals (HS280530), the second-largest global exporter after China, with about 70% going to Japan.
Midstream: The Overlooked Rayong Toll-Processing Niche
Most coverage of Thailand’s position stops at beneficiation, but that misses a genuine, if small, midstream capability. Neo Performance Materials holds a 20% interest in GQD Special Material (Thailand) Co. Ltd., a joint venture operating a toll-processing facility in Rayong. According to Neo’s 2026 Annual Information Form, GQD converts neodymium oxide sourced from Neo’s Silmet plant in Estonia into metal form, which then feeds Neo’s Magnequench operation in Korat. This adds a genuine Thailand rare earth midstream link that bypasses China entirely for part of the material, an unusual feature for a Southeast Asian supply chain this size.
Downstream: Magnequench Korat and the EV Manufacturing Cluster
Magnequench Korat (MQK), in Nakhon Ratchasima, is the only commercial-scale bonded NdFeB magnetic powder facility in Southeast Asia. Established in 1999 and spanning 25,600 square metres, the plant has operated for more than 25 years. Company disclosures put Thailand rare earth magnet powder capacity at roughly 2,000 tonnes, part of about 10,000 tons installed worldwide and 4,000 tons outside China, split evenly between Thailand and a newer European facility.
That capacity sits close to a genuine downstream demand cluster. BYD’s Rayong plant, opened in July 2024 with capacity for 150,000 vehicles a year, has passed 130,000 domestic deliveries as of July 2026 and has been exporting Dolphin EVs to Europe since August 2025. Great Wall Motor operates a separate “Smart Factory” in Rayong, fully GWM-owned, producing multiple Ora, Haval and Tank models for the Thai and regional market. Neither company sources magnets exclusively from Thailand, but their presence illustrates why a domestic magnetic powder facility matters strategically even at modest scale.
The US MOU: Diversification Push and Domestic Backlash
On 26 October 2025, Thai Prime Minister Anutin Charnvirakul and US President Donald Trump signed a memorandum of understanding on critical minerals cooperation on the sidelines of the ASEAN Summit in Kuala Lumpur. The agreement, non-legally-binding, covers exploration, refining, recycling and investment promotion. A near-identical MOU was signed with Malaysia around the same time, part of a wider set of US deals with Southeast Asian partners that also included Cambodia and Vietnam.
The MOU was not uncontroversial domestically. Four days after signing, a coalition of 27 NGOs protested outside the US Embassy in Bangkok, objecting to a clause seen as granting US firms priority access to Thailand’s mineral resources and warning that the agreement bypassed standard permitting procedures under Thailand’s Minerals Act. Opposition figures from the Pheu Thai Party and the People’s Party criticised the government for signing without prior parliamentary consultation, with one MP for Chiang Mai describing the deal as making Thailand “a pawn in the rare earth war between China and the US.”
The Transboundary Pollution Crisis
Thailand’s rare earth story is inseparable from an unresolved environmental crisis originating across its northern border. Unregulated mining in Myanmar’s Shan State, much of it in areas controlled by armed groups rather than the Myanmar state, has been linked to arsenic and heavy metal contamination in the Kok, Sai and Ruak rivers, and in the Mekong mainstream as far downstream as the Golden Triangle confluence at Sop Ruak. Thailand’s Pollution Control Department has recorded arsenic levels multiple times above WHO safe limits at various testing points since testing intensified in 2025, and research groups have separately detected dysprosium and terbium, both heavy rare earths, in Kok River sediment, tying the contamination specifically to rare earth extraction rather than gold mining alone in at least some stretches.
The rivers supply tap water and irrigation to communities across Chiang Rai and Chiang Mai provinces, affecting an estimated 1.2 million people. A Thailand-Myanmar joint panel was agreed in August 2025, but as of mid-2026 civil society groups describe the government’s response as inadequate, and a monk-led march along the Kok River took place on 6 June 2026, World Environment Day, to draw attention to the continuing pollution.
Thailand Rare Earth Outlook
Thailand rare earth supply chain position is narrower than headline mine production figures once suggested, and the revised USGS data make that narrower position clearer still. What Thailand actually offers is a beneficiation and toll-processing waypoint feeding a single, longstanding magnet powder facility, sitting next to a genuine EV manufacturing cluster that has real if partial demand for those magnets. The US MOU signals interest in formalising Thailand’s role in a diversified, non-Chinese supply chain, but it does not resolve the more immediate problem on Thailand’s own rivers, which originates outside its borders and outside its control. China’s October 2025 export controls remain suspended until 10 November 2026, a date that will matter more to Thailand’s beneficiation trade than the MOU does in the near term.
Does Thailand mine rare earth elements domestically?
No. Thailand has no commercial rare earth mining. Domestic firms import raw ore and beneficiate it, separating rare earth-bearing minerals from host rock before export, mostly to China for refining.
What is Thailand’s current rare earth production ranking?
Thailand produced an estimated 4,800 tonnes of REO equivalent in 2025, the fifth-largest national total globally, according to USGS data published in February 2026.
What does Magnequench Korat produce?
Magnequench Korat, operated by Neo Performance Materials, is the only commercial-scale bonded NdFeB magnetic powder facility in Southeast Asia, with roughly 2,000 tonnes of installed capacity.
What did the US-Thailand critical minerals MOU cover?
Signed on 26 October 2025 by PM Anutin Charnvirakul and President Trump, the non-binding MOU covers cooperation on exploration, refining, recycling and investment promotion in critical minerals.
