Sourcing NdFeB magnets in France means understanding that there is no virgin French sintered-magnet production. The genuine French developments are upstream, rare-earth refining at Solvay and the new Caremag plant at Lacq, plus one recycled-magnet maker, MagREEsource. Everything else machines, assembles, or distributes imported magnets.
This guide separates the real French and EU producers from the import-and-distribute houses, and from the factory-direct international suppliers that carry the volume.
01 · What to look for
What buyers actually need from an NdFeB supplier
For a procurement engineer, the hard part isn't finding a company that will sell you magnets. It's finding one you can actually qualify: one that holds spec at temperature, ships certified to your industry, prices honestly, and keeps shipping when tariffs and export rules move. A supplier worth shortlisting covers:
EU rules and supplier diversification. The EU has no DFARS-style ban on Chinese-origin magnets in defence. The Critical Raw Materials Act sets 2030 targets and caps any single third country at 65% of supply; buyers are also exposed to China's own export licensing. Plan for diversification and a licensed, continuity-capable supplier.
Certifications matched to your industry. IATF 16949 for automotive, AS9100 for aerospace, ISO 13485 for medical, ISO 9001 as a baseline. The certification your industry demands is a hard gate, regardless of price.
Magnet cost and GBD. On high-temperature grades, heavy-rare-earth (Dy/Tb) content drives cost. Grain-boundary diffusion (GBD) holds coercivity while cutting Dy/Tb sharply (factory-verified: 75% less Dy), usually the largest single cost lever.
European, recycled, or imported. French recycled (MagREEsource) and EU sintered (VAC, Neo) supply suit specific supply-security or sustainability goals but are capacity-limited; for most commercial requirements, qualified imported supply is the practical route.
Assembly vs. bare magnets. A finished, magnetized, balanced assembly built to your drawing removes magnet handling and magnetizing from your line, often worth more than the per-kilogram price.
Supply continuity and second-sourcing. Tariffs and export controls move fast. A qualified second source with in-house export licensing is the difference between a price negotiation and a stopped line.
The best magnet supplier isn't the one with the longest grade list. It's the one that can prove the grade holds at your operating temperature, certify it to your industry, and keep the line fed when the supply chain moves.

Need a second source that keeps the line moving?
Mainrich qualifies as a factory-direct commercial source with in-house export licensing, so a qualified order keeps shipping through tariff and export-control disruption.
10.Calamit (Aimants Calamit)
Paris, France (group: Italy)
Distributor and converter of NdFeB, ferrite, SmCo, and AlNiCo magnets and magnetic systems for the French market.
Suppliers are labelled by type so buyers can match a source to their end-use. Mainrich is listed first as our own recommendation for commercial-volume sourcing, and is labelled honestly as an international factory-direct supplier, not a domestic French producer. Company facts (location, founding year, certifications) reflect public information and may change, so verify current certifications directly with each supplier during qualification.

The State of French NdFeB Supply
The EU imports roughly 98% of its rare-earth permanent magnets, and only about 1,000 of the ~20,000 tonnes consumed each year are made in Europe. In France specifically there is no virgin sintered-NdFeB production: the only genuine French maker is MagREEsource (Grenoble), producing sintered magnets from 100% recycled feedstock at small scale.
France's weight is upstream, Solvay's La Rochelle plant is the largest rare-earth separation site outside China, and Carester's Caremag refinery at Lacq is commissioning around late 2026 (oxides, not magnets). The nearest volume sintered NdFeB serving French buyers is Vacuumschmelze (Germany) and Neo (Estonia). For most commercial volume, a French buyer is choosing a supplier, not a country.
04 · Our Position
Where Mainrich Fits
International factory-direct
Mainrich International is included as what it is: an international, factory-direct NdFeB supplier serving French and EU buyers, not a French manufacturer. For genuinely French or European material, MagREEsource, VAC, and Neo above are the names to know. For commercial programs, Mainrich competes on the full grade range (N30-N58 through AH), GBD that cuts Dy/Tb cost (factory-verified: 75% less Dy), finished assemblies built to drawing, IATF 16949 quality across the production network, and in-house export licensing so a qualified order keeps shipping through China's export-control regime. The honest role we ask for is the qualified commercial source and the second source that keeps the line moving.
FAQ · Questions
Frequently Asked Questions
Are there neodymium (NdFeB) magnet manufacturers in France?
There is no virgin sintered-NdFeB production in France. The only genuine French NdFeB maker is MagREEsource (Grenoble), which produces sintered magnets from 100% recycled feedstock at small scale. France's other strengths are upstream, rare-earth refining at Solvay (La Rochelle) and the Caremag plant at Lacq (commissioning ~2026), while established French houses such as Euromag and Braillon machine, assemble, or build systems from imported material. The nearest volume sintered NdFeB serving France is Vacuumschmelze (Germany) and Neo (Estonia).
Does France or the EU ban Chinese-made magnets in defence, like the US does?
No. There is no EU or French equivalent to the US DFARS rule. The EU's approach is the Critical Raw Materials Act, 2030 targets for domestic extraction, processing, and recycling, plus a cap of 65% of supply from any single third country, rather than a country-of-origin ban. French buyers are, however, exposed to China's own export-licensing controls on rare-earth magnets.
Is it cheaper to source magnets in France or to import them?
For most commercial NdFeB volume, qualified imported supply is the cost backbone, because roughly 98% of EU rare-earth magnets are imported and France has no virgin sintered production. French recycled (MagREEsource) and EU sintered (VAC, Neo) supply suit specific goals. The largest single cost lever on high-temperature grades is the heavy-rare-earth content, which GBD can cut sharply while holding coercivity (factory-verified: 75% less Dy).
What certifications should a magnet supplier have?
Match the certification to your industry: IATF 16949 for automotive, AS9100 for aerospace, ISO 13485 for medical, ISO 9001 as a baseline. A supplier without the certification your program requires cannot be qualified regardless of price, so screen on this first.
What is GBD and why does it lower magnet cost?
Grain-boundary diffusion (GBD) diffuses heavy rare earths (dysprosium and terbium) along the grain boundaries of a sintered NdFeB magnet rather than throughout the bulk, achieving the same high-temperature coercivity with far less Dy/Tb (factory-verified: 75% less Dy, no Br loss). Because those heavy rare earths are the most expensive, supply-constrained inputs, GBD directly lowers cost.
