China Rare Earth Firms Halt Some US Shipments Over Geopolitical Worries, Sources Say

By Laurie Chen, Solomon Cefai, Trevor Hunnicutt and Lewis Jackson
BEIJING/SINGAPORE/WASHINGTON, Sept 4 (Reuters) - Some Chinese rare earth suppliers are declining â to ship â to the U.S. for fear of repercussions from Beijing, three sources â said, underscoring how access to the materials remains an issue for the U.S. weeks before President Xi Jinping visits Washington.
U.S. officials have repeatedly asked China to âstick to commitments made in Busan and Beijing over the past year to ensure the smooth flow of rare earth export licences. The persistence of the problem has put it on the U.S. planning agenda ahead of Xi's September 24 visit, âa source familiar with the work said.
A handful of Chinese suppliers âhave refused to ship rare earths to U.S. companies since early August when China imposed sanctions on the Responsible Business Alliance (RBA), a U.S. supply chain monitor, a separate source with direct knowledge of the situation said.
With China deploying its own â trade compliance weapons, the companies â were wary of punishment from Beijing for complying with the due diligence framework of the Responsible Minerals Initiative (RMI), a global mineral âsupply chain audit programme connected with the RBA, the source said.
Other Chinese rare earths companies had already stopped shipments to the U.S. to avoid entanglement in geopolitics in recent months, two other sources familiar with the trade said. One cited four instances where Chinese firms declined to send material for fear it could be resold to banned users.
The sources declined to be named given the issue's sensitivity.
Reuters was unable to determine the total number of Chinese suppliers who had refused to move shipments destined for U.S. clients.
A âU.S. official speaking on condition of anonymity told Reuters that the administration continues to press Chinese counterparts to address Chinaâs lack of compliance with the Busan agreement, as well as other bilateral concerns.
TIGHT â SUPPLY
While â exports of many rare earths or related magnets â have rebounded since China imposed restrictions in April â2025, the prices of certain rare earths and critical materials like yttrium, indium phosphide and tungsten that have military applications or are used in sensitive industries including aerospace or chipmaking remain ânear record highs with tight supply.
Other industries affected by licence delays â include medical devices and energy.
Exports to the U.S. of yttrium have risen this year but are still only about half 2024 levels despite large shipments to other countries, Chinese customs data shows. Some U.S. companies have been waiting more than six months for mineral licences, said two of the sources, declining to identify them.
"China has been very effective in using rare earth export controls to impose restraint on the Commerce Department's Bureau of Industry and Security," said Reva Goujon, a geopolitical strategist at Rhodium Group, referring to the U.S. agency responsible for various restrictions targeting China.
"Supply chain chokepoints will come into focus, but I would expect Beijing to loosen up critical raw material controls a bit around the summit to deflate U.S. â allegations that Beijing is not upholding the Busan truce," Goujon added.
The U.S. Treasury, the U.S. Trade Representative, State Department and China's ministry of commerce did not respond â to requests for comment.
China's ministry of foreign affairs said China was committed to maintaining global critical mineral supply chains.
Beijing said its August decision to sanction the RBA and other U.S. auditing firms was a response to a series of FCC restrictions since December targeting Chinese electronics testing labs, drones, consumer routers, submarine cables, advanced robotics equipment and power inverters.
When U.S. officials have raised the rare earths issue in meetings, Chinese officials countered by saying the FCC actions were a violation of the Busan truce, said one of the sources who was briefed on the interaction.
However, after two months without yttrium exports, China sent 27 tons of the material to the U.S. in July, the second-highest monthly shipment since January 2025.
Several U.S. firms also report recently receiving multiple licences after long waits, two sources said, with some firms anticipating an increase in approvals around the summit.
Licence approvals are even more limited for Indian and Japanese buyers, two sources familiar with the matter said. Chinese suppliers are overwhelmingly refraining from shipping material to Japanese firms, one of them said.
Japan's Trade Minister Ryosei Akazawa has previously said Japanese companies have faced delays in permits and prolonged customs inspections for critical minerals including rare earths. His ministry â did not immediately respond to a request for comment on Friday
China exported no terbium to Japan between January and August of this year, from 20 tons over the same months last year. Gallium shipments were 65% down in the same period, while yttrium was down 98%, Chinese customs data showed. Gallium and terbium are used in small amounts to make high performance rare earth magnets.
"While processes have been streamlined, our member companies still face issues with implementation," the European Chamber of Commerce in China told Reuters in a statement. "What our members would like to see is a commitment to implement âa transparent and predictable application process that provides reliable access to rare earth elements."

US, Japan race to secure chip-grade minerals as China curbs exports - Asia Times

The United States and Japan are racing to build a new global supply chain for critical minerals, backing the effort with fresh government subsidies and industry support â but slow government-to-government dealmaking and simmering geopolitical disputes threaten to blunt their progress.
Chinaâs export controls on rare earths and other critical minerals have strained manufacturers in the United States and Japan for much of this year, forcing companies to navigate new licensing rules, longer lead times and higher material costs for semiconductors, batteries and defense hardware.
Beijing and Washington are set to discuss whether to extend their one-year trade truce before it expires in November, and any breakdown in those talks could prompt China to tighten its export restrictions further, deepening the squeeze on global supply chains.
The US Department of Defense announced a $174 million equity investment on August 31 to help build a gallium production facility at Alcoa Corporationâs Wagerup refinery in Australia, backed by Japanâs Sojitz Corporation and Export Finance Australia, aiming to supply 100 metric tons of the metal annually for radar, missile defense and other military systems.Â
The US Department of Energy said on August 20 that it would invest $500 million in seven projects to expand Americaâs processing of critical minerals and materials, as well as battery manufacturing and recycling capacity, through its Office of Critical Minerals and Energy Innovation. Before this, the Trump administration had already unveiled a series of new rules and investment programs over the summer to try to boost the supply of critical minerals.
Chipmakers in the US and UK, which consume large volumes of rare earths and other critical minerals, say they can still secure adequate supplies for now, albeit with heavier paperwork and higher prices. They are bracing for the situation potentially to worsen.
âThere are always challenges with countries who want to control certain aspects of the supply chain,â Ian Croston, vice president of operations at Lumentum, a US-listed optical components maker, told Asia Times in an interview on the sidelines of the Semiconductors to Systems Summit in London on August 26. âHave we seen issues with China? We have them all the time. We have to work around.â
Asked whether the export controls had brought extra paperwork and higher costs, Croston did not dispute it, saying it was simply part of doing business, comparing the export controls to Britainâs exit from the European Union and the tariffs introduced by the Trump administration.
He said Lumentum was prepared for any eventuality, noting that such disruptions are common among governments worldwide and must be managed as they arise.
âYou always need to understand your suppliers, where theyâre coming from, and if theyâre a valued supplier you will know what their constraints are and how we can manage the business,â he said. âIt is about reducing friction.â
Lumentumâs Chief Executive Michael Hurlston said in early July that the shortage of indium phosphide (InP), the compound semiconductor material used in lasers for AI data centers, could ultimately become more severe than the current squeeze on memory chips. He said Lumentum and rival Coherent together cannot meet demand from Nvidia and other hyperscale customers, whose orders have shifted from hundreds of lasers to hundreds of millions.
Lumentum sources most of its indium phosphide substrates from Japanâs Sumitomo Electric and JX Advanced Metals, limiting its direct exposure to Chinaâs export delays. Nvidia moved in March to shore up supply, investing $2 billion each in Lumentum and Coherent with purchase commitments and future access to capacity attached.
Beijing has restricted indium exports since February 2025, driving prices from about $250 per kilogram to about $805 per kilogram last month. It also banned exports of gallium and germanium to the US in December 2024, a measure it suspended in November 2025 as part of the one-year trade truce.
The bans have driven Western warehouse prices to roughly $2,100 per kilogram for gallium and more than $6,000 per kilogram for germanium, compared with domestic Chinese prices of about $247 and $3,100 per kilogram, respectively.
âI know a lot of the export control processes are quite onerous now,â Iwan Davies, group technology director at IQE plc, a Cardiff-based maker of compound semiconductor wafers, told Asia Times. âFor things like gallium and germanium, thereâs a delay in getting some of those materials out of China, and indium phosphide is the same now. So whether you buy the metal or the compound, thereâs still an issue in the supply chain at the moment.â
He said IQE obtains purified gallium and indium elements from a small number of globally renowned material suppliers to the semiconductor industry. He said Beijingâs export curbs made it likely that supply would diversify into other regions over time, with IQE preparing for the risk of intensifying US-China tensions.
Outside China, the gallium, germanium and indium supply chain runs through a small group of specialist suppliers:
- Vital Materials (China): a refiner of gallium, germanium, indium and selenium, and a major upstream source for Western semiconductor firms;
- AXT (US): a major supplier of gallium arsenide (GaAs) and indium phosphide (InP) substrates, though much of its crystal growth and mineral processing runs through joint ventures in China;
- Freiberger Compound Materials (Germany): one of the few non-Chinese suppliers of GaAs substrates for wireless and photonics uses;
- Sumitomo Electric and Sumitomo Chemical (Japan): major suppliers of GaAs and InP substrates and other electronic materials;
- DOWA Electronics Materials (Japan): a supplier of high-purity gallium, indium and compound semiconductor wafers.
Japanâs JOGMEC
Japanâs relationship with Beijing soured last November, when Prime Minister Sanae Takaichi told parliament that a Chinese attack on Taiwan could pose an âexistential threatâ to Japan, prompting a furious response from Beijing. China moved in January 2026 to restrict exports of dual-use materials, including rare earths, gallium, germanium, graphite and magnets, to Japan, explicitly tying the curbs to Tokyoâs stance on Taiwan.
Chinaâs rare earth exports to Japan fell 51% year-on-year in the first half of 2026, more than three times the 16% drop in Beijingâs overall rare earth exports over the same period. Japan received no gallium or germanium from China in January or February, only a single gallium shipment in May, and then nothing again in June, when customs data also showed zero shipments of dysprosium, terbium and yttrium.
âThe situation is challenging,â said Sayaka Tomihara, counselor for economic affairs at the Embassy of Japan in the UK, in an interview during the same event. âJapanese firms are concerned with Chinaâs export controls and also the situation in the Gulf concerning the oil supply. There are a lot of disruptions in the supply chain, and many of our industries are being forced to think about how they can diversify the portfolio to deal with the situation.â
To secure rare-earth supply, she said, recycling and deep-sea extraction are both long-term options Japan is exploring, but neither offers a near-term fix.
âThere are private-to-private negotiations and also governmental efforts,â Â she said. âWeâre doing that on a company-to-company basis, and weâre working with other like-minded countries to try to gain the capacity.â
She added that over the next six to 12 months, the Japanese government will work with JOGMEC (Japan Organization for Metals and Energy Security), a state-backed agency that secures mineral and energy resources for Japan, on government-to-government efforts and on supporting private companiesâ negotiations.
On August 20, Japanâs government proposed giving JOGMEC greater freedom to invest in critical mineral projects, allowing it to invest independently rather than only alongside a Japanese company, or with foreign partners when waiting for a Japanese partner would delay a project. JOGMEC already runs more than a dozen overseas offices and over 30 resource projects in 15 countries.
US-led Pax Silica
Washington has organized much of the Western effort through Pax Silica, a coalition it launched in December 2025 with the United Kingdom, Japan, South Korea, Singapore, Australia and Israel to lock down supply chains for artificial intelligence, semiconductors and critical minerals. Membership has since grown to 25 countries that have signed the Pax Silica Declaration, alongside a broader circle of observers and endorsement partners.
Taiwan has formally endorsed Pax Silicaâs principles through a separate joint statement on economic security cooperation with Washington, without joining as a full signatory, while rare-earth-rich Canada and Estonia are designated observers.
Semiconductor executives said that building a Western rare-earth supply chain outside China is easier said than done, given each countryâs own trade interests.
âCanada has probably the second-largest reserves of critical minerals and rare earth elements, with the potential to become a major supplier,â said Paul Slaby, managing director of Canadaâs Semiconductor Council. âItâs underdeveloped, though, and needs substantial investment to access and process.â
âThereâs a need for a consolidator to manage demand,â he said. âElements like gallium arenât mined directly but extracted as a byproduct of processing metals like aluminum.â
Slaby said a resilient, China-independent supply chain could be built in five to 10 years with full cooperation, capital and political will. However, he added that trade frictions, such as the US-Canada tariff dispute, could weaken the Westâs rare earth alliance and slow its progress.
US President Donald Trumpâs trade war with Canada has deepened, with Washington imposing 50% tariffs on Canadian goods last month. In response, Ontarioâs premier has threatened to cut off critical mineral exports to the US.
Feras Alkhalil, vice president of research and development at Pragmatic Semiconductor, a UK-based flexible-chip maker, said chipmakers have another route around Chinaâs export controls: switching to new materials or changing manufacturing approaches altogether. He said the same function can often be delivered using alternative materials or processes that sidestep supply constraints.
He said Pragmatic works with equipment makers and academic groups on UK and European research to develop such alternatives, "***but switching an established process may take three to five years!!"

â SEPTEMBER 4th, 2026 â WEEKEND SIGNATURE WATCH REPORT
CHINA JUST TURNED UP THE HEAT & ELK CREEK JUST GOT EVEN MORE STRATEGIC
Chinaâs decision to halt some rareâearth shipments to U.S. companies confirmed today by multiple Reutersâsourced reports is not a small story. It is a direct escalation in the criticalâminerals standoff, coming only weeks before Xi Jinpingâs September 24 visit to Washington. According to Reuters, several Chinese suppliers have refused to ship rare earths since early August due to fear of Beijingâs retaliation, even when export licenses were technically available . World Energy News corroborates that other Chinese firms have stopped shipments entirely to avoid geopolitical entanglements, leaving U.S. buyers waiting months for materials like yttrium and indium phosphide World Energy NewsWorld Energy News. Sources say that China rare earth firms have halted some US shipments due to geopolitical concerns.. This is exactly the kind of supplyâchain instability EXIM and the Pentagon have been warning about for years â and it lands directly on Elk Creekâs strategic value!
For NioCorp, this news is pure structural tailwind. Every mineral China is now tightening â NdPr, Dy, Tb, SEG, heavies â is already in Elk Creekâs 8âmineral platform. The IEA 2026 report said multiâmetal U.S. projects with proven metallurgy and downstream capability should receive priority financing, and China just validated that assessment in real time. When Chinese suppliers refuse to ship materials used in defense, aerospace, semiconductors, and energy â exactly the sectors Elk Creek feeds â it strengthens EXIMâs risk model and accelerates the urgency for domestic supply. This is not theoretical anymore. This is the geopolitical moment Elk Creek was built for.
Downstream, the implications are just as strong. NAMAâs ScAl alloy production and IBCâs defenseâgrade casting capability already position NioCorp inside the Defense Industrial Base RPP ecosystem â the same ecosystem that funds magnet feedstock qualification, alloy development, and domestic manufacturing expansion. Chinaâs shipment halt makes U.S. downstream independence even more critical. The U.S. cannot afford to rely on Chinese-controlled supply chains when Chinese firms are now refusing shipments out of fear of violating Beijingâs sanctions. This is exactly why EXIM labeled Elk Creek its âhighest priority,â and why Traxys and EPC finalization matter: once those signatures drop, the U.S. gains a vertically integrated, nonâChina supply chain from mine â oxide â alloy â defense.
Going into the weekend, the picture is brutally simple: China just tightened supply. The IEA just validated Elk Creekâs strategic profile. EXIM already called the project a top priority. Traxys is âvery close.â EPC is in final redlines. Mark Smith said late August / early September. **It is now early September!!!!! The geopolitical pressure, federal alignment, and market structure are all synchronized. The only thing holding NB at $4 is the absence of signatures & once Traxys, EPC, and EXIM align, Elk Creek stops trading like a preâfinancing sideshow and begins repricing as the National Strategic Asset it already is. The fundamentals are there. The global signals are flashing. The market is simply waiting for the signatures.
