Chinese rare earth suppliers are delaying or declining some shipments to U.S. and Japanese buyers even after export licenses have been approved, adding a new layer of uncertainty to critical-minerals supply chains already strained by tighter controls and geopolitical tensions.
The pullback is selective rather than a blanket export ban. Some cargoes continue to move, and several U.S. companies have secured licenses after lengthy waits. But suppliers are increasingly reluctant to complete transactions when they face uncertainty over end users, potential resale and the risk of punishment from Beijing, according to people familiar with the shipments cited by Reuters.
The development changes the risk calculation for manufacturers of electric vehicles, aerospace systems, defense equipment, industrial motors and electronics. For buyers, a license is becoming a necessary condition for supply: but not always a guarantee that material will leave China.
Suppliers weigh political and compliance risks
Some Chinese exporters reportedly began refusing U.S.-bound shipments as early as August, even after licenses had been issued. Others have delayed deliveries or subjected orders to additional scrutiny, Reuters reported, citing three people familiar with the trade.
The suppliers’ concerns extend beyond the formal wording of an export approval. They must also determine whether a shipment could reach a restricted end user, be resold to a sanctioned entity or become associated with a foreign compliance system that Chinese authorities oppose.
The concerns intensified after China sanctioned the Responsible Business Alliance, a U.S.-based supply-chain monitoring group. Chinese companies have also raised objections to due-diligence frameworks linked to the Responsible Minerals Initiative, according to the Reuters report.
That has created a compliance dilemma for exporters. U.S. and Japanese buyers increasingly require documentation covering mineral origin, processing routes, end use and downstream customers. Chinese suppliers, however, may view some of those audits or disclosures as exposing them to domestic regulatory risk.
The result is an unusual gap between legal authorization and commercial execution. An exporter may hold an approved license while still deciding that the shipment is too risky to release.

Export controls remain in force
China began requiring licenses in April 2025 for exports of seven medium and heavy rare earths and related products, including dysprosium, terbium and yttrium. The materials are important in high-performance permanent magnets used in electric motors, aircraft systems, wind turbines, precision weapons and industrial automation.
The licensing system has remained in place even as some broader export-control measures were paused or adjusted. S&P Global Commodity Insights has warned that bottlenecks could persist through 2026 as companies navigate licensing requirements, end-user restrictions and China’s dominant position in processing and magnet production.
Chinese export controls have also been applied to specific foreign companies. In June, China added MP Materials, USA Rare Earth and other U.S. entities to an export-control list, according to Reuters.
The policy environment means buyers must assess more than whether a product is technically available. They must also consider whether the supplier, product category, end user and destination remain acceptable under China’s evolving dual-use rules.
U.S. flows remain volatile
U.S.-bound shipments have not stopped completely, but volumes have been uneven.
Data summarized by the Silverado Policy Accelerator showed that exports of controlled rare earth compounds and metals to the United States were extremely limited in the opening months of the year. Shipments briefly improved in the spring before weakening again, illustrating how quickly trade flows can change.
U.S. Trade Representative Jamieson Greer said in May that Chinese exports to the United States were improving but that Beijing remained slow to approve some shipments, according to Reuters reporting.
There have also been signs of selective easing. Reuters reported in August that Chinese yttrium exports to the United States rose in July, offering some relief to aerospace buyers that depend on the material. The increase did not amount to a broad normalization of supply.
China’s Ministry of Commerce has said its rare earth controls are lawful and that it will review compliant civilian export applications in accordance with regulations. But month-to-month changes in shipment volumes suggest that buyers are still operating in a discretionary and politically sensitive market.
For manufacturers, that volatility complicates production planning. A company may receive approval for one shipment while facing delays on a second order for the same material, depending on the supplier, end user or product specification.
Japan faces a sharper squeeze
Japanese buyers are encountering similar obstacles, with industry sources telling Reuters that Chinese suppliers have been broadly reluctant to ship rare earth materials to Japan.
Japan’s trade minister, Ryosei Akazawa, has said Japanese companies are facing delays in permits and prolonged customs inspections for critical minerals, according to the Reuters report. The pressure follows a deterioration in relations between Beijing and Tokyo over Taiwan and broader security policy.
Trade data cited by the Silverado Policy Accelerator and other analysts indicate that exports of controlled rare earth compounds and metals to Japan fell sharply after China introduced tighter dual-use restrictions. Shipments were reported at zero in January and only a small volume in February, compared with monthly averages above 100 metric tons during the second half of the previous year.
Reuters has also reported that China sent no gallium, dysprosium, terbium or yttrium to Japan in certain recent months. These materials are particularly important for high-performance magnets and other precision applications.
Japanese automakers, electronics manufacturers and industrial-equipment producers can draw on inventories or redirect material between facilities in the short term. But prolonged delays could raise procurement costs, extend lead times and force companies to qualify alternative materials or suppliers.
The disruption may be difficult to resolve quickly. Even when alternative rare earth feedstock is available from Australia, the United States or another mining jurisdiction, it must still be separated, refined, converted into alloys and manufactured into magnets. China remains dominant across much of that midstream chain.

What buyers must monitor
The immediate risk for U.S. and Japanese companies is not necessarily a complete cutoff. It is the loss of predictability.
Procurement teams must now track several variables at the same time:
- License approval times: Applications may remain pending for months, particularly for controlled heavy rare earths.
- End-user restrictions: Suppliers may reject orders connected to defense, aerospace or other sensitive applications.
- Downstream ownership: A shipment can face scrutiny if material could be resold or transferred to a restricted entity.
- Compliance requirements: Foreign due-diligence programs may create additional political or legal exposure for Chinese exporters.
- Customs inspections: Cargo can be delayed even after licensing steps appear complete.
- Inventory coverage: Manufacturers may need larger stockpiles of dysprosium, terbium, yttrium and finished magnets.
- Alternative processing capacity: Non-Chinese mines do not automatically provide non-Chinese refined supply.
Defense contractors and aerospace manufacturers face particular challenges because substitute materials often require lengthy testing and certification. A technically available alternative may not be suitable for immediate use in an aircraft, missile system, motor or other regulated product.
The same issue applies to electric vehicles and industrial automation. Replacing a magnet supplier may require redesign work, new qualification testing and changes to manufacturing processes: not simply a new purchase order.
Diversification extends beyond mining
The latest shipment delays underline why supply-chain diversification cannot focus solely on developing new mines.
New production can reduce reliance on Chinese ore supply, but buyers also need independent separation plants, metal and alloy capacity, magnet factories, recycling systems and transport routes. Each link requires capital, permitting, skilled labor, power and long-term customers.
The European Union’s experience illustrates the challenge. The European Commission says China supplies the bloc with all of its heavy rare earth processing. At the same time, the European Court of Auditors has warned that strategic critical-minerals projects continue to face financing, permitting and market-access obstacles.
Those constraints are relevant to U.S. and Japanese buyers because new mines alone will not resolve shortfalls in refined materials or permanent magnets. Supply-chain resilience will depend on whether projects can move from strategic announcements to commercial operations.
For operators, investors and policymakers, the central question is therefore shifting. It is no longer simply whether rare earths exist in the ground. It is whether material can move through a chain of licenses, processors, manufacturers, customs authorities and end users without interruption.
China’s selective shipment refusals show how quickly that chain can tighten. Until alternative refining and magnet capacity reaches scale, U.S. and Japanese buyers will remain exposed to both formal export controls and the risk that suppliers decide not to ship: even when the paperwork is approved.
