China Imposes Export Controls on Key REE

Immediate Retaliation to US April 2025 Tariffs

05 April 2025

Geoeconomic Tensions Escalate Amid Targeted Restrictions

​In retaliation to President Donald Trump's announcement on April 2, 2025, of reciprocal tariffs on Chinese imports, China’s Ministry of Finance declared on April 4 that all US-origin goods will be subject to an additional 34% tariff, effective April 10, 2025, and is on top of an existing 20% that had already been imposed earlier this year.

Concurrently, China’s Ministry of Commerce and the General Administration of Customs issued Announcement No. 18 of 2025, introducing export controls on a range of medium and heavy rare earth elements. These measures took immediate effect and were enacted under the legal frameworks of the Export Control Law, Foreign Trade Law, and regulations governing dual-use items. 

Beijing cited national security, strategic interests, and non-proliferation obligations as the rationale behind the restrictions, marking a sharp escalation in the ongoing trade and technology confrontation between the Trump administration and China.

China’s export restrictions apply to specific forms of the following elements, including their compounds, alloys, oxides, and target materials, and extend across a wide range of material formats integral to industrial and high-tech manufacturing, ensuring comprehensive coverage from raw material processing to advanced component fabrication.

  • Alloys encompass standard industrial formats such as ingots, bars, rods, wires, plates, tubes, particles, and powders.

  • Target materials include sheet, tube, and other specialised forms designed for thin-film deposition and precision manufacturing applications.

  • Permanent magnets refer to both finished magnetic materials and magnetic powders, including those used in high-performance NdFeB systems.

  • Oxides, compounds, and mixtures are covered in all processed forms, including powders and blended compositions, regardless of physical state.

China’s REE Export Controls Threaten US Security and Technology Sectors

China’s export controls on key medium and heavy rare earth elements pose significant risks to US national security, defence manufacturing, and high-tech industries. The restricted elements, particularly samarium, dysprosium, terbium, and scandium, are essential for producing high-performance permanent magnets used in advanced missile systems, fighter jets, and directed energy weapons. Samarium-cobalt and NdFeB magnets enhanced with dysprosium or terbium are especially critical due to their ability to operate under extreme conditions.

Beyond defence, the controls on gadolinium, lutetium, and yttrium impact US healthcare, nuclear energy, and photonics sectors. Gadolinium is vital for MRI contrast agents and nuclear reactor shielding; lutetium supports PET imaging and precision optics; and yttrium is used in lasers and high-temperature ceramics.

The US has limited domestic capacity to mine, refine, or process many of these elements, leaving critical supply chains exposed. With China as the dominant global supplier, the new controls could trigger material shortages, price volatility, and urgent pressure to accelerate domestic and allied sourcing strategies, including investment in recycling, stockpiling, and alternative production partnerships.

 

Sectors at Risk

Chinese Export Controls Target Critical Inputs for Defence, Energy, and Advanced Manufacturing

China has introduced sweeping export controls on a select group of medium and heavy rare earth elements vital to global high-tech, defence, and clean energy supply chains. The move, framed as a national security measure, tightens Beijing’s grip on materials essential for producing high-performance magnets, advanced alloys, precision optics, and medical imaging technologies.

The restricted materials, ranging from samarium and dysprosium to scandium and yttrium, play critical roles in applications as diverse as missile guidance systems, electric vehicles, PET scanners, and satellite components. These new controls threaten to further disrupt already fragile global supply chains, especially for countries heavily reliant on Chinese exports, including the United States, Japan, and members of the EU.

What follows is a breakdown of the key rare earth elements now under restriction and their strategic applications across defence, energy, and advanced manufacturing sectors:

Scandium — Scandium metal and its alloys with aluminium, magnesium, and copper are now subject to export control. These lightweight, high-strength materials are prized in aerospace and advanced manufacturing. Scandium targets, oxides, and chemical compounds are also covered, potentially disrupting emerging markets for scandium-aluminium alloys in next-gen aircraft and EVs.

Yttrium — Yttrium metal, along with a wide range of yttrium-based alloys—including combinations with aluminium, magnesium, nickel, copper, and iron—are now restricted. Yttrium-containing target materials, oxides, compounds, and mixtures also fall under the new rules. Yttrium is a vital input for phosphors in lighting, lasers, and advanced ceramic applications, making this a broad-spectrum restriction.

Samarium — China’s new export controls cover samarium metal, samarium-containing alloys—including those with cobalt, iron, nickel, aluminium, and magnesium—as well as associated target materials and permanent magnet components. Samarium-cobalt magnets, which are essential in aerospace and military applications due to their high-temperature stability and magnetic strength, are specifically included. The restrictions also apply to samarium oxides, compounds, and blended materials in various forms.

Gadolinium - Gadolinium exports are now restricted in metallic form, as well as in magnesium and aluminium alloys. The controls extend to gadolinium-based target materials, commonly used in thin-film technologies and imaging systems, and to gadolinium oxides, compounds, and mixtures. Given its key role in medical imaging and neutron shielding in nuclear reactors, the move may impact sectors beyond defence.

Terbium — Export limitations now apply to terbium metal, terbium-cobalt and terbium-cobalt-iron alloys, and target materials containing terbium. The inclusion of NdFeB (neodymium-iron-boron) magnets enhanced with terbium—used to improve magnetic performance at high temperatures—highlights China's grip on the high-performance magnet supply chain. Terbium oxides and compounds are also subject to control.

Dysprosium, a critical additive in high-coercivity permanent magnets, is now under export control in metallic and alloy forms, particularly in dysprosium-iron and terbium-dysprosium-iron configurations. Dysprosium-containing targets and NdFeB magnets are included, as are its oxides, compounds, and any mixtures. These restrictions will likely affect producers of advanced motors and military-grade actuators.

Lutetium — Controls on lutetium include the pure metal, ytterbium-lutetium alloys, and lutetium-based target materials. Lutetium oxides, compounds, and mixtures—used in PET scan detectors and specialised optics—are also restricted. Though less well-known, lutetium’s rarity and high value make it strategically significant in advanced photonics and medical technology.

China’s Sanctions Strategy: Expanding Economic Statecraft

Since 2022, China has increasingly leveraged economic tools to counter perceived threats from the United States. While Lockheed Martin and Raytheon were the initial targets, the ripple effects of Beijing’s policies now extend across a broad swath of the defence, aerospace, semiconductor, and dual-use technology landscape.

China’s expanding sanctions framework represents a calculated and intensifying response to U.S. technology controls and mounting geopolitical pressure. By targeting a growing array of defence contractors, aerospace firms, AI developers, and critical supply chain actors, Beijing is wielding economic statecraft as a strategic instrument of national security and foreign policy.

More than a retaliatory measure, this evolving regime reflects China’s broader ambition to shape the global technological order by leveraging its dominant position in key supply chains. Sanctions and export controls are becoming proactive tools of influence, aimed at reshaping global dependencies and asserting long-term strategic leverage. For U.S. firms operating in sensitive sectors, the risk of being drawn into Beijing’s geoeconomic crosshairs is rising rapidly.

Targeted Sectors and Escalating Measures

To date, more than 60 U.S. companies have been affected by Chinese sanctions or export restrictions. The consequences for supply chain resilience, defence readiness, and technological cooperation are becoming increasingly apparent. If geopolitical tensions continue to escalate, additional firms, particularly in emerging technologies, semiconductors, and dual-use manufacturing, are likely to face similar penalties.

Companies listed under China’s dual-use export control regime are now barred from receiving Chinese-origin goods, materials, and technologies. These restrictions are expected to disrupt global supply chains tied to military platforms, surveillance systems, aerospace components, and semiconductor devices. The policy signals a broader shift in Beijing’s strategy, using export controls not only to retaliate, but to exert strategic leverage over rival powers. Sectors most affected include defence, aerospace, logistics, and advanced technology, where reliance on Chinese inputs remains substantial.

Firms designated on China’s "Unreliable Entities List" face particularly severe penalties: bans on trade with Chinese companies, prohibitions on investment, asset freezes, and restrictions on executive travel to China. These designations effectively sever access to the Chinese market, imposing both economic costs and strategic deterrence.

In 2024, China imposed two significant rounds of sanctions targeting U.S. defence and semiconductor companies, particularly those supplying advanced systems to Taiwan’s military. The second wave, announced on 27 December, added seven firms to the restricted entity list. These sanctions included asset freezes and a ban on transactions with Chinese entities, while also extending export controls to high-bandwidth memory (HBM) chips—critical for AI training and next-generation defence platforms.

In 2023, Beijing sanctioned several U.S. firms linked to arms sales to Taiwan and military logistics. This included subsidiaries of Raytheon Technologies, Lockheed Martin Corporation, and General Dynamics. These actions involved asset freezes and trade bans. That same year, China also sanctioned 13 U.S. defence firms and six executives, expanding the Unreliable Entities List. Simultaneously, six Chinese companies were penalised for allegedly assisting Iran’s missile and drone programmes—signalling China’s selective enforcement of non-proliferation principles in line with its geopolitical agenda.

The first major step in this strategy came in 2022, when China sanctioned Lockheed Martin Corporation and Raytheon Missiles & Defense, the inaugural additions to the Unreliable Entities List. Sanctions included bans on trade and investment, as well as restrictions on executive travel and residency. That year, China also tightened its Export Control Catalogue for dual-use items, broadening controls on sensitive technologies without naming further companies.
