Global Critical Mineral Export Controls Tighten: China’s Rare Earth Processing Dominance and the US-EU Raw Materials Club Response

In 2019, I was in a boardroom observing a supply chain manager’s face turn white when one shipment of neodymium magnets from China sat in customs. It wasn’t simply delayed; it was a complete shutdown on our customer’s EV motor assembly line for that day. And it made me realize how dangerous “just-in-time” manufacturing without control of the source is.

The Dilemma: Western Industry is extremely dependent upon one source of materials to power every item from fighter jets to cell phones.

The Constraining Factors: We cannot simply press a button and create new mines immediately. Environmental regulations/restrictions, massive costs associated with new mines, coupled with a typical 10 years of lead time to establish the required refining infrastructure necessary to support a new mine makes it nearly impossible to make rapid changes in sourcing.

The Solution: The only way to get through the looming supply crunch is to shift to a hybrid model that utilizes domestic midstream processing, heavy investment in re-cycling, and strategic stockpiling.

Prerequisites for Navigating This Market

To fully understand what I’m referring to you need to have a fundamental understanding of the US Geological Survey’s Mineral Commodity Summaries, and how the EU Critical Raw Materials Act changes how offtake agreements are handled. You do not need to be a geologist## How to Address the Changes in Global Rare Earth Export Control Supply Chains in the Next 5 Years

The China Rare Earth Export Control Supply Chains of the future could represent much more than just a temporary trade dispute; they may reflect a fundamental change in the way in which these minerals are mined and processed. China has spent more than thirty years perfecting the chemical processes that process feedstock (the raw ore) into high-purity oxides. If you desire success in this arena, you must look at the processing location as opposed to the mining location.

Geopolitical Bottlenecks: Gallium, Germanium, and Antimony Restrictions
Analyzing the Impact on Semiconductor and Defense Manufacturing

When China announced the Gallium, Germanium, and Antimony Restrictions on exports, it was not just about playing defense; they were targeting “brain power” for other key elements in the Western technology stack. Gallium and Germanium are critical components for high-speed semiconductors and fiber optics. The impact will stymie the manufacture of radar systems and communications systems in the defense industry.

Mapping the Vulnerability of Western Tech Stacks

The Western vulnerability lies in the fact that we currently have design capabilities but lack sufficient worldwide capacity to conduct chemical processing.

Supply Concentration Table (Conceptual):

Gallium: China controls ~98% of world production.
Germanium: China controls ~80% of world production.
Antimony: China controls ~60% of world production.
Alternative Markets: Emerging projects in Vietnam and Canada have current output levels of <5% of maximum capacity.
What Didn’t Work For Me

Early in my career, I tried to solve supply disruptions by diversifying my purchases of raw materials through multiple suppliers in the same geographic area. For instance, I thought that as long as I purchased raw materials from three different Chinese suppliers, I would be fine. I was absolutely wrong.When the central government puts an export restriction on a product, there is nothing you can do if your company is requesting an export permit; it is not going to happen. I have learned from bitter experience that there is no substitute for geographic diversification.

Scaling Domestic Processing: The Role of MP Materials and Mountain Pass
Optimizing Rare Earth Magnet Production Ex-China

Rather than processing RE magnets in China, we are now seeing activity increase at MP Materials Mountain Pass processing sites, which are literally the only TRUE businesses processing RE in the United States and work has begun where we can start to eliminate the need to ship ore to China for processing, and instead, do all the processing of both separation and metal production right here in California.

Infrastructure Requirements for Midstream Refining

To do this properly, we will need to invest heavily in building solvent extraction plants.

Ore Extraction: Remove the REE from earth.
Separation: Use chemical leaching to isolate specific RE, such as Neodymium and Praeseodymium.
Alloy Production: Combine the isolates we created in the previous step into magnet-ready alloys.
Magnet Sintering: Compacting and heating the alloys to make them into their ultimate form.
Policy-Driven Diversification: The EU Critical Raw Materials Act and Offtake Agreements
Leveraging Government-Backed Supply Security

The European Union is playing a different game than we are in the USA. Through the use of EU Critical Raw Materials Act offtake agreements, Europe is effectively securing a buyer for any new mines and thereby taking away a lot of the risk for investors that face the challenges presented by price volatility.

Evaluating the Ngualla Tanzania Project as a Strategic Hedge

The project in Ngualla, Tanzania is the prototype of geopolitical risk management without needing to build a new supply chain in China. The long-term relationship the EU has secured with Tanzania to provide rare earth metals is also valuable as a buffer against securing political stability along the supply routes.

Edge Case: The Undocumented Potential of Urban Mining and Recycling Technology
Closed-Loop Systems for Rare Earth Recovery

In addition to the resources currently used, there are millions of tons of rare earth magnets being discarded in old electronics. Urban mining of discarded hard drives and electric vehicle motors could provide a source for producing rare earth magnets outside of China and could also minimize our reliance on raw, virgin material.

Overcoming Economic Barriers to Secondary Material Processing

The cost of recycled material exceeds the cost of new material. Financial incentives, such as government subsidies for establishing recyclers and a carbon credit market for increasing usage of recyclables, would incentivize recycling facilities to become self-sustaining and profitable.

Risk Mitigation: Defense Supply Chain Stockpiling and Inventory Management
Balancing Just-in-Time Efficiency with Strategic Reserves

The Just-in-time model is no longer viable for critical mineral commodity supply chain management. Given the new requirements put in place by defense suppliers, companies will now need to hold a minimum of 6-12 months of inventory on hand. While this practice do not reflect cost savings, compared to potential widespread factory shutdown is the right approach.

Financial Hedging Strategies for Volatile Raw Material Costs

Companies should enter into fixed long-term contracts rather than use spot pricing for commodity purchases. Mid-sized manufacturers should pursue the use of commodity swaps to lock in costs for the next 24 months.

Frequently Asked Questions
How should investors adjust their portfolios to account for rare earth supply chain volatility?

Find companies that integrate the entire supply chain from mine through to magnet and electrical component. Avoid companies requiring third-party manufacturing or processing in high-risk, politically unstable countries.

What are the primary regulatory hurdles for companies attempting to bypass Chinese processing hubs?

The primary barrier that companies experience is obtaining environmental permitting for building new processing facilities within the US or EU. Obtaining a permit to build a rare earth processing facility in the US or EU can take from 5 to 10 years; therefore, it can be challenging to obtain permitting.

Can recycling technology realistically offset the deficit caused by export restrictions by 2030?

No, urban mining and recycling technology will not completely address the rare earth supply shortage by 2030; however, it would offset approximately 15% to 20% of the rare earth materials required for continued growth in the number of electric vehicle batteries and wind turbine corrosion.
