Brazil’s 2026 Rare Earth Policy: Impact on NdFeB Magnets

As countries compete to secure critical minerals, rare earth supply chains are becoming increasingly influenced by government policies, investment restrictions, and industrial strategies.

In September 2026, Brazil introduced a new national policy for critical and strategic minerals, strengthening oversight of certain foreign investments and encouraging domestic mineral processing.

As a country with substantial rare earth reserves, Brazil could play an important role in future supply chain diversification. However, developing mineral resources is only one part of building a reliable supply chain for high-performance permanent magnets.

For manufacturers sourcing sintered NdFeB magnets, the key question is not simply where rare earth minerals are mined, but whether those resources can be transformed into qualified magnetic materials and finished magnets at an industrial scale.

1. What Has Changed in Brazil’s Rare Earth Policy?

On September 16, 2026, Brazil enacted Law No. 15,506/2026, establishing the National Policy on Critical and Strategic Minerals (PNMCE).

The policy aims to strengthen national oversight of strategic mineral resources while supporting domestic processing, industrial development, and technological innovation.

Several developments are particularly relevant to international supply chains:

-Greater investment oversight: Certain transactions involving foreign investors and strategic mineral assets may face additional government review.

-Domestic value creation: Brazil aims to encourage more mineral processing and industrial activities within the country rather than relying primarily on raw material exports.

-Supply chain development: The policy supports investment, research, and industrial capabilities related to critical minerals.

Importantly, the new framework does not represent a blanket prohibition on foreign investment or mineral exports.

Instead, it reflects a broader global trend in which resource-rich countries seek greater participation in downstream manufacturing and higher-value industrial activities.

For international buyers, this development highlights how government policies can influence the availability, cost, and long-term stability of critical raw materials.

2. Why Rare Earth Reserves Do Not Automatically Create a Magnet Supply Chain

Brazil has significant rare earth resources, but mineral reserves alone do not guarantee an immediate alternative supply of finished permanent magnets.

The production of sintered neodymium iron boron (NdFeB) magnets involves several interconnected stages:

Rare Earth Mining → Separation & Refining → Metal & Alloy Production → Magnet Manufacturing → Precision Machining → Coating & Magnetization

Each stage requires specialized technology, manufacturing expertise, and quality control.

China currently maintains a dominant position in global rare earth refining and permanent magnet manufacturing. As a result, developing alternative mining projects does not immediately eliminate dependence on existing processing and manufacturing infrastructure.

For example, rare earth elements such as neodymium (Nd) and praseodymium (Pr) are essential components of NdFeB magnets, while dysprosium (Dy) and terbium (Tb) may be used in certain high-temperature applications.

However, converting these materials into high-performance magnets requires precise control of material composition, magnetic properties, and manufacturing processes.

Even when rare earth minerals originate outside China, downstream processing may still take place in China.

This distinction is particularly important for companies seeking non-China-origin magnetic materials.

A diversified mining supply does not necessarily mean that qualified magnet materials are immediately available from multiple countries.

3. What Does This Mean for NdFeB Magnet Buyers?

Brazil’s policy changes are unlikely to cause an immediate transformation of the global NdFeB magnet market. However, they reinforce several important considerations for industrial buyers.

Material Origin and Supply Chain Transparency

Manufacturers increasingly need to understand not only where finished magnets are produced, but also where their magnetic materials originate.

A magnet manufactured in Vietnam, for example, may use magnetic materials sourced from China, Japan, or other countries.

Therefore, the manufacturing location and material origin should be evaluated separately.

In addition, the country of manufacture does not automatically determine a product’s legal country of origin. Applicable rules of origin and actual production processes must also be considered.

Availability of Alternative Magnetic Materials

Non-China-origin NdFeB materials can provide additional sourcing options, but availability varies depending on magnet grade, performance requirements, and production volume.

For industrial applications requiring grades such as N48SH, N50H, or other high-coercivity materials, buyers should carefully evaluate:

-Magnetic performance, including Br and Hcj.

-Operating temperature and irreversible magnetic flux loss.

-Minimum order quantities (MOQ).

-Material costs and production lead times.

Switching material suppliers may also require additional engineering evaluation and product qualification.

Long-Term Supply Chain Resilience

For manufacturers of electric motors, industrial automation equipment, and electronic components, supply chain diversification should focus on practical manufacturing capabilities rather than material origin alone.

A reliable sourcing strategy should consider material availability, processing capabilities, quality consistency, and delivery performance.

The central lesson is clear: Diversifying rare earth resources is not the same as diversifying the NdFeB magnet supply chain.

4. How Can Vietnam Support Magnet Supply Chain Diversification?

As global manufacturers evaluate alternative production locations, Vietnam is becoming an increasingly relevant manufacturing option for industrial components, including permanent magnets.

For NdFeB magnet buyers, Vietnam-based manufacturing can provide additional flexibility in downstream production and supplier selection.

However, effective diversification requires more than relocating the final manufacturing process.

Companies should evaluate whether a potential supplier can support different material sources, maintain consistent magnetic performance, and meet customized manufacturing requirements.

At SINOWIN Industrial (Vietnam), we support international customers with customized sintered NdFeB magnet manufacturing, including:

-Precision machining of customized magnet geometries.

-Surface treatments, including NiCuNi coating.

-Magnetization and magnetic performance inspection.

-Evaluation of magnetic materials from different sourcing regions.

-Manufacturing support for industrial motors, automation systems, and electronic applications.

Depending on project requirements, SINOWIN can evaluate magnetic materials sourced from China and selected overseas suppliers.

Material availability, applicable grades, MOQ, and lead times are assessed individually to ensure technical and commercial feasibility.

For buyers considering alternative manufacturing locations, the objective should be to establish a supply chain that balances material performance, sourcing flexibility, manufacturing reliability, and cost competitiveness.

Conclusion

Brazil’s 2026 critical minerals policy reflects a broader shift in how governments manage strategic resources and develop domestic industries.

While new mining projects may gradually expand global rare earth supply options, building a diversified NdFeB magnet supply chain requires investment across refining, material production, and manufacturing.

For industrial buyers, understanding these differences is essential when evaluating alternative sourcing strategies.
