China's rare earth magnet controls: How companies can build resilient supply chains

The regulatory landscape is volatile. Controls target magnets containing dysprosium, terbium, and samarium, but even products without these elements face increased scrutiny at customs. Export volumes have fluctuated sharply, and while some restrictions have been postponed, uncertainty remains the norm. The future of these controls will likely hinge on broader geopolitical developments and the state of China’s relations with the U.S. and EU.

What does this mean for companies? Magnet supply from China will remain unpredictable. Some supply chains may stabilize for the time being, but none will be safe from future disruptions. Unpredictability is structural, not temporal. The key to resilience is not just reacting to the latest policy, but building robust, transparent, and flexible supply strategies.

From challenge to solution: What companies can do now

Drawing on years of on-the-ground experience and policy analysis, here are practical approaches companies can take—regardless of size or sector—to manage risk and secure their magnet supply.

1. Build true supply chain transparency

Many companies underestimate their dependence on China because magnets often appear deep in the supply chain—at tier-3 or tier-4 supplier levels. These hidden dependencies may only surface when a disruption occurs, leaving little time to react.

Solution:

• Map your entire magnet supply chain, down to the sub-tier supplier level.
• Identify where Chinese content enters your products, and which suppliers are most exposed to export controls.
• Use this transparency to anticipate risks and develop contingency plans before issues arise.

2. Monitor policy and market developments proactively

China's export controls are not random, they reflect specific geopolitical and domestic policy dynamics. Companies that monitor, analyze, and forecast these developments are better positioned to anticipate disruptions.

Solution:

• Establish a regular process for tracking and interpret regulatory changes and market signals.
• Conduct scenario planning: What happens if controls tighten? What if they ease?
• Quantify the potential impact on price, lead time, and license risk for your key products.

3. Develop comprehensive risk profiles

Risks are not limited to tier-1 suppliers. Vulnerabilities can exist deep in the supply chain, and at the level of specific part numbers.

Solution:

• Combine supply chain transparency with policy assessment to create detailed risk profiles.
• Prioritize critical supply chains and make informed procurement decisions based on real exposure, not assumptions.

4. Rethink sourcing and supplier strategies

Export controls affect different stages of the value chain in different ways. The classic “make-or-buy” decision matrix needs to be revisited.

Solution:

• Reassess your supplier portfolio at every stage, from raw materials to finished magnets.
• Consider dual sourcing models and regional clusters to mitigate local disruptions.
• Evaluate suppliers not just on price, but on their ability to navigate export controls and maintain compliance.

5. Strengthen supplier relationships and communication

Chinese suppliers face their own risks and pressures. Building sustainable, trust-based relationships is essential, especially in times of crisis.

Solution:

• Invest in long-term, multilevel engagement with key suppliers.
• Support local supplier management activities and maintain open, reliable communication channels.
• Involve experienced local and international teams to bridge cultural and regulatory gaps.

6. Prepare for export control compliance

Chinese regulations require extensive information disclosure from non-Chinese customers. Navigating this process efficiently is crucial.

Solution:

• Work closely with suppliers to provide the necessary documentation.
• Understand the regulatory requirements in detail to avoid unnecessary delays or compliance risks.
• Build export control clauses and contingency plans into contracts.

7. Establish ongoing monitoring and crisis response

The supplier landscape is evolving rapidly. Ongoing monitoring and the ability to respond quickly to crises are vital.

Solution:

• Set up regular supply chain reviews and monitoring systems to catch emerging risks early.
• Develop crisis mitigation plans, including rapid-response teams and alternative sourcing options.
• Maintain a stable, trusted team that can act quickly when disruptions occur.

Segment-specific approaches: One size does not fit all

For large enterprises:

• Implement group-wide policies on Chinese content, stockpiling, and dual sourcing.
• Design steering committees to make fast, informed decisions under different scenarios.
• Use “war-room” support models for rapid response to disruptions.
• Actively manage board-level pressure, ESG obligations, or regulatory exposure.

For mid-sized companies:

• Conduct tailored health checks: analyze spend, screen for risk, and scan top suppliers for sustainability.
• Run managed sourcing projects from RFQ to first delivery, including supplier vetting and export-control-ready documentation.
• Focus on resource constraints and realistic solutions.

For small businesses:

• Keep solutions simple and pragmatic—avoid over-engineering.
• Use starter kits for specification guidance and vetted distributor lists.
• Join buyer clubs or pooled advisory services to gain leverage and share insights.
• Make the organization aware of the danger of relying on opaque traders.
