In mid-January, a high United States supplies firm introduced that it had began to fabricate uncommon earth magnets. It was vital information—there aren’t any giant U.S. makers of the neodymium magnets that underpin enormous and vitally vital business and protection industries, together with electrical autos. But it surely created barely a ripple throughout a very loud and stormy time in U.S. commerce relations.
The press launch, from MP Supplies, was gentle on particulars. The corporate disclosed that it had began producing the magnets, referred to as neodymium-iron-boron (NdFeB), on a “trial” foundation and that the manufacturing unit would start regularly ramping up manufacturing earlier than the tip of this yr. In line with MP’s spokesman, Matt Sloustcher, the ability could have an preliminary capability of 1,000 tonnes every year, and has the infrastructure in place to scale as much as 2,000 to three,000 tonnes per yr. The discharge additionally mentioned that the ability, in Fort Value, Texas, would provide magnets to Common Motors and different U.S. producers.
NdFeB magnets are essentially the most highly effective and worthwhile kind. They’re utilized in motors for electrical autos and for heating, ventilating, and cooling (HVAC) methods, in wind-turbine turbines, in instruments and home equipment, and in audio audio system, amongst different gear. They’re additionally important elements of numerous navy methods and platforms, together with fighter and bomber plane, submarines, precision guided weapons, night-vision methods, and radars.
A magnet manufacturing surge fueled by Protection {dollars}
MP Supplies’ has named its new, state-of-the-art magnet manufacturing facility Independence.Enterprise Wire
The Texas facility, which MP Supplies has named Independence, just isn’t the one main rare-earth-magnet undertaking within the U.S. Most notably, Vacuumschmelze GmbH, a magnet maker primarily based in Hanau, Germany, has begun developing a plant in South Carolina by means of a North American subsidiary, e-VAC Magnetics. To construct the US $500 million manufacturing unit, the corporate secured $335 million in exterior funds, together with not less than $100 million from the U.S. authorities. (E-VAC, too, has touted a provide settlement with Common Motors for its future magnets.)
In one other intriguing U.S. rare-earth magnet undertaking, Noveon Magnetics, in San Marcos, Texas, is at the moment producing what it claims are “business portions” of NdFeB magnets. Nonetheless, the corporate just isn’t making the magnets in the usual method, beginning with metallic alloys, however slightly in a novel course of primarily based on recycling the supplies from discarded magnets. USA Uncommon Earth introduced on 8 January that it had manufactured a small quantity of NdFeB magnets at a plant in Stillwater, Oklahoma.
One more firm, Quadrant Magnetics, introduced in January, 2022, that it will start development on a $100 million NdFeB magnet manufacturing unit in Louisville, Kentucky. Nonetheless, 11 months later, U.S. federal brokers arrested three of the corporate’s high executives, charging them with passing off Chinese language-made magnets as domestically produced and giving confidential U.S. navy knowledge to Chinese language businesses.
The a number of US neodymium-magnet tasks are noteworthy however even collectively they received’t make a noticeable dent in China’s dominance. “Let me provide you with a actuality verify,” says Steve Constantinides, an IEEE member and magnet-industry advisor primarily based in Honeoye, N.Y. “The overall manufacturing of neo magnets was someplace between 220 and 240 thousand tonnes in 2024,” he says, including that 85 % of the overall, not less than, was produced in China. And “the 15 % that was not made in China was made in Japan, primarily, or in Vietnam.” (Different estimates put China’s share of the neodymium magnet market as excessive as 90 %.)
However have a look at the figures from a distinct angle, suggests MP Supplies’s Sloustcher. “The U.S. imports simply 7,000 tonnes of NdFeB magnets per yr,” he factors out. “So in whole, these [U.S.] amenities can supplant a major share of U.S. imports, assist re-start an {industry}, and scale because the manufacturing of motors and different magnet-dependent industries” returns to the USA, he argues.
And but, it’s onerous to not be a bit awed by China’s supremacy. The nation has some 300 producers of rare-earth everlasting magnets, in accordance with Constantinides. The biggest of those, JL MAG Uncommon-Earth Co. Ltd., in Ganzhou, produced not less than 25,000 tonnes of neodymium magnets final yr, Constantinides figures. (The corporate lately introduced that it was constructing one other facility, to start working in 2026, that it says will deliver its put in capability to 60,000 tonnes a yr.)
That 25,000 tonnes determine is similar to the mixed output of all of the rare-earth magnet makers that aren’t in China. The $500-million e-VAC plant being inbuilt South Carolina, for instance, is reportedly designed to provide round 1,500 tonnes a yr.
However even these numbers don’t absolutely convey China’s dominance of everlasting magnet manufacturing. The place ever a manufacturing unit is, making neodymium magnets requires provides of rare-earth metallic, and that just about all the time leads straight again to China. “Although they solely produce, say, 85 % of the magnets, they’re producing 97 % of the metallic” on the planet, says Constantinides. “So the magnet producers in Japan and Europe are extremely depending on the rare-earth metallic coming from China.”
MP’s Mine-to-Manufacturing stragegy
And there, not less than, MP Supplies might have an fascinating edge. Hardly any companies, even in China, do what MP is making an attempt: produce completed magnets beginning with ore that the corporate mines itself. Even giant corporations usually carry out only one or at most two of the 4 main steps alongside the trail to creating a rare-earth magnet: mining the ore, refining the ore into rare-earth oxides, decreasing the oxides to metals, after which, lastly, utilizing the metals to make magnets. Every step is a gigantic enterprise requiring fully completely different tools, processes, information, and ability units.

“The one benefit they get from [doing it all] is that they get higher insights into how completely different markets are literally rising,” says Stan Trout, a magnet {industry} advisor in Denver, Colorado. “Getting the timing proper on any enlargement is vital,” Trout provides. “And so MP ought to be getting that data in addition to anyone, with the completely different crops that they’ve, as a result of they work together with the market in a number of other ways and might actually see what demand is like in actual time, slightly than as some projection in a forecast.”
Nonetheless, it’s going to be an uphill climb. “There’s are loads of each onerous and tender subsidies within the provide chain in China,” says John Ormerod, an {industry} advisor primarily based in Knoxville, Tenn. “It’s going to be tough for a US producer to compete with the present worth ranges of Chinese language-made magnets,” he concludes.
And it’s not going to get higher any time quickly. China’s rare-earth magnet makers are solely utilizing about 60 % of their manufacturing capability, in accordance with each Constantinides and Ormerod—and but they’re persevering with to construct new crops. “There’s going to be roughly 500,000 tonnes of capability by the tip of this yr,” says Ormerod, citing figures gathered by Singapore-based analyst Thomas Kruemmer. “The demand is simply about 50 % of that.”
The upshot, the entire analysts agree, can be downward worth stress on uncommon earth magnets within the close to future, not less than. On the similar time, the U.S. Division of Protection has made it a requirement that rare-earth magnets for its methods have to be produced fully, beginning with ore, in “pleasant” international locations—which doesn’t embody China. “The DoD might want to pay a premium over cheaper imported magnets to ascertain a worth flooring enabling home U.S. producers to efficiently and repeatedly provide the DoD,” says Constantinides.
However is what’s good for America good for Common Motors, on this case? We’re all going to search out out in a yr or two. In the mean time, few analysts are bullish on the prospect.
“The automotive {industry} has been extraordinarily cost-conscious, demanding provider worth reductions of even fractions of a cent per piece,” notes Constantinides. And even the Trump administration’s tariffs are unlikely to change the essential math of market economics, he provides. “The appliance of tariffs to magnets in an try to ‘degree the enjoying discipline’ incentivizes corporations to search out work-arounds, comparable to exporting magnets from China to Malaysia or Mexico, then re-exporting from there to the USA. This isn’t theoretical, these work-arounds have been used for many years to keep away from even the previous or present low tariff charges of about 3.5 %.”
