The use of HREE-free NdFeB magnets is a method to enhance supply chain resilience. HREE-free NdFeB magnets are also a key focus of this article.
The Background of Rare Earth Export Control Policy

Against the backdrop of escalating trade tensions between China and the United States, China announced in April 2024 that it would suspend the export of seven heavy rare earth metals and rare earth magnets, requiring special permits for these products to be shipped abroad. This move is seen as a response to the Trump administration’s increase in tariffs on April 2.
Classification of Light Rare Earth Elements and Heavy Rare Earth Elements
| Light Rare Earth Elements: Including lanthanum, cerium, praseodymium, neodymium, promethium, samarium, and europium, or referred to as cerium group rare earths, which have lower atomic numbers and smaller masses.

| Heavy Rare Earth Elements: Including gadolinium (Gd), terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. These elements have high atomic numbers and larger masses. Gadolinium, which shares similar chemical properties with the heavy rare-earth elements, is often included in the heavy rare-earth subgroup; hence, heavy rare-earth elements are also referred to as gadolinium-group rare-earth elements.
Solution: Providing Neodymium Magnets without Controlled Rare Earth Elements
This chart provides a snapshot of our latest progress in Dy/Tb-free NdFeB development. It highlights a range of grades—some already confirmed free of these heavy REEs, others still in active R&D. These grades span a broad spectrum of magnetic properties, from remanence to coercivity, underscoring our commitment to delivering high-performance solutions without relying on sensitive elements.

Benefits of HREE-free NdFeB Magnets
| Supply Chain: Reducing Dependence on Rare Earth Price Volatility. The price of heavy rare earth elements is influenced by various factors, including supply and demand, resulting in significant fluctuations. By using magnets, HREE-free NdFeB magnets, sensitivity to these factors can be decreased, resulting in more stable product costs.
| Lower Raw Material Costs: The extraction and costs of heavy rare earth elements are high. Utilizing HREE-free NdFeB magnets that do not contain heavy rare earth elements can lead to lower raw material costs.
