China’s rare-earth export-control framework has changed how permanent-magnet buyers, manufacturers, freight forwarders, and downstream equipment companies plan cross-border supply. The practical effect is not a blanket ban on all NdFeB magnets. It is a classification-and-licensing system that places greater importance on exact composition, product form, end user, end use, documentation, and lead-time planning.
Status note – July 19, 2026: China’s April 2025 controls on specified medium and heavy rare-earth items remain the core rule relevant to samarium-cobalt materials and NdFeB magnets containing terbium or dysprosium. Some broader measures announced on October 9, 2025 were later suspended through November 10, 2026. Companies should distinguish the active April controls from the suspended October measures and confirm the latest official notice before shipment.
What the April 2025 Rules Cover
On April 4, 2025, China’s Ministry of Commerce and General Administration of Customs issued Announcement No. 18 of 2025. It placed specified samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium-related items under export control. For the permanent-magnet sector, the list includes samarium-cobalt permanent-magnet materials and NdFeB permanent-magnet materials containing terbium or dysprosium.
Exporters of controlled items must apply for a dual-use export license and accurately identify the item in customs declarations. The official list and control codes, rather than a commercial product name alone, determine whether a shipment is covered.
Why Composition Matters More Than the Grade Name
Commercial labels such as N42SH, N35UH, or “high-temperature NdFeB” are not by themselves sufficient for export classification. Different producers can reach a coercivity target through different formulations and grain-boundary diffusion processes. A high-temperature magnet may contain dysprosium or terbium, but the amount and distribution depend on the material route.
For an export review, buyers and suppliers may need controlled access to composition statements, material certificates, product drawings, process descriptions, and end-use information. Procurement teams should avoid assuming that two magnets with the same nominal grade have identical regulatory status.
Simple Magnet Components Versus Deeply Processed Products
The China Export Control Information website published a 2026 frequently asked questions notice clarifying that simple further-processed products made from controlled permanent-magnet materials – such as pieces, arcs, rings, and related magnetic components – remain within the controlled scope. The notice also states that deeply processed electronic components or products, such as motors, loudspeakers, and headphones, are not within that specific scope.
This distinction is operationally important, but it should not be treated as a universal exemption. Product configuration, actual composition, control-list wording, end user, and end use still need review. When classification is uncertain, the official guidance recommends consultation rather than assumption.
Which Later Measures Are Suspended?
China announced additional rare-earth, equipment, technology, and extraterritorial measures in October 2025. The Ministry of Commerce and General Administration of Customs later issued Announcement No. 70 of 2025, suspending implementation of Announcements 55, 56, 57, 58, 61, and 62 through November 10, 2026. An April 2026 official response reiterated that suspension period.
Announcement No. 18 is not included in the listed suspended measures. Therefore, companies should not interpret the suspension of the October package as removal of the April 2025 controls.
Impact on the Permanent Magnet Supply Chain
1. Longer and less predictable lead times for controlled products
Manufacturing time is only one part of delivery. Classification, preparation of end-user and end-use documents, license review, customs questions, and logistics coordination can add time. A buyer who confirms regulatory information only after production may create an avoidable shipping delay.
2. Greater demand for traceable material data
Magnet producers need stronger batch traceability between raw material, alloy, powder, sintered block, finished magnet, coating, and shipment. Importers may request more detailed certificates and declarations. This improves transparency but also increases the cost of documentation and internal control.
3. More attention to heavy-rare-earth-efficient designs
Engineering teams have additional incentive to reduce dysprosium and terbium use where performance allows. Options include improved cooling, a more favorable magnetic circuit, increased magnet thickness, lower reverse field, grain-boundary diffusion, alternative NdFeB formulations, SmCo, ferrite, or changes to the motor topology. Any substitution must be validated for irreversible demagnetization, flux, torque, corrosion, and reliability.
4. Inventory and contract terms become more important
Buyers may hold more safety stock for controlled materials or critical magnet grades. Contracts increasingly need clear responsibilities for classification data, license support, end-use statements, schedule changes, cancellation, and regulatory force-majeure events. Blanket inventory expansion is expensive, so risk should be segmented by grade, application, and source.
5. Qualification of alternative sources accelerates
Global customers are evaluating additional magnet-making capacity, recycling routes, and regional supply chains. Qualification is not quick: equivalent dimensions and grade labels do not guarantee the same demagnetization curve, coating quality, flux distribution, or process capability. Dual sourcing requires sample validation, audit, traceability, and change-control rules.
6. Downstream manufacturers need compliance workflows
Motor, sensor, actuator, medical-device, robotics, and consumer-electronics companies may not export a controlled magnet as a standalone item, but they still depend on compliant upstream supply. They need a process to collect end-use information, protect confidential data, review restricted parties, and respond quickly to supplier questions.
What Buyers Can Do Now
- Identify which parts use SmCo or NdFeB formulations containing Dy or Tb.
- Request composition and control-status confirmation at the quotation stage.
- Provide accurate end-user, end-use, destination, and application information early.
- Separate manufacturing lead time from possible licensing and customs time.
- Maintain approved alternatives for critical grades and assemblies.
- Validate low-heavy-rare-earth designs rather than changing grade names only.
- Define documentation, confidentiality, and regulatory-change responsibilities in supply agreements.
- Check the latest official Chinese control list and announcements before every controlled shipment.
What Suppliers Should Strengthen
Magnet suppliers should maintain product-classification procedures, batch-level composition traceability, restricted-party screening, end-use review, document retention, and a clear escalation path for uncertain transactions. Sales teams should not promise shipment dates before the compliance route is understood. Engineering, export-control, and logistics teams need to work from the same product data.
Will the Policy Permanently Raise Magnet Prices?
Export controls can add compliance cost, inventory cost, and delivery risk, but magnet prices are also driven by rare-earth oxide and metal markets, capacity utilization, energy, processing yield, grade, coating, machining, and demand from electric vehicles, wind power, industrial automation, and electronics. The policy can amplify volatility without being the only cause of price movement.
For procurement, the most useful response is not to predict one price direction. It is to improve specification discipline, forecast visibility, design alternatives, and contractual planning.
Frequently Asked Questions
Are all NdFeB magnet exports from China controlled?
No. The April 2025 control list specifically includes NdFeB permanent-magnet materials containing terbium or dysprosium, among other listed rare-earth items. Actual classification must follow the official control description and product facts.
Does an export-control license mean a shipment is prohibited?
No. A controlled item generally requires an application and government review. Approval is not automatic, and the end user and end use matter, but control is different from a universal ban.
Are the October 2025 rare-earth measures currently active?
The measures specifically listed in Announcement No. 70 are suspended through November 10, 2026. This does not suspend Announcement No. 18 of April 2025.
