Key Takeaways
- ◆India consumes rare-earth magnets but does not yet make them at scale — about 93% of its permanent-magnet imports come from China, and domestic sintered NdFeB is pilot-stage.
- ◆The genuine domestic build-out is early: ARCI runs an NdFeB pilot line, IREL makes samarium-cobalt (not NdFeB) at kg scale, and Midwest plus the ₹7,280-crore government scheme aim at commercial NdFeB later this decade.
- ◆Most Indian 'NdFeB manufacturers' import sintered magnets and machine, assemble, or build them into separators and systems — true in-house sintering is rare.
- ◆India has relaxed EV-motor magnet localization (extending import permission) precisely because domestic supply cannot yet meet demand.
- ◆For commercial volume today, the practical route is a qualified factory-direct international supplier vetted on IATF 16949, GBD cost, and supply continuity.
Sourcing NdFeB magnets in India starts from a clear reality: India consumes rare-earth magnets but does not yet make them at scale. Domestic production is pilot-stage, and roughly 93% of permanent-magnet imports come from China. A serious government push is underway, but most Indian 'magnet manufacturers' today import sintered material and add machining, assembly, or systems. This guide separates the genuine Indian players and emerging producers from the import-and-assemble houses, and from the factory-direct international suppliers that meet most demand now.
The State of U.S. NdFeB Supply
India's permanent-magnet imports nearly doubled to around 57,000 tonnes in FY2024-25, roughly 93% of it from China, and for finished sintered NdFeB the import dependency approaches 100%. Domestic production is genuinely emerging but early: ARCI (Hyderabad) runs an end-to-end NdFeB pilot line, IREL produces samarium-cobalt magnets (not NdFeB) at kilogram scale, and the larger commercial build-out — Midwest Advanced Materials' planned plant and the government's ₹7,280-crore sintered-magnet scheme — is under construction or out for bids, not yet producing. Most established Indian magnet companies make AlNiCo, ferrite, or assemblies, or build magnetic-separation equipment, consuming imported NdFeB rather than sintering it. The most defensible point for a buyer today: for commercial NdFeB volume in India, you are choosing a supplier, and that supplier is almost always importing.

How to Choose a Magnet Supplier
Domestic vs. imported reality
India has no commercial sintered-NdFeB production yet; domestic players largely import and assemble. For finished magnets you are choosing between an Indian import-and-assemble house and a factory-direct international source — usually on cost and lead time.
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 30-50% — usually the largest single cost lever.
Defense and indigenization rules
India restricts Chinese-origin components in some military procurement (indigenization lists), but there is no civilian ban — commercial Chinese NdFeB imports remain legal and dominant. Confirm requirements for defense end-use.
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.
Where Mainrich Fits
Mainrich International is included as what it is: an international, factory-direct NdFeB supplier serving Indian buyers, not an Indian manufacturer. Because India has no commercial sintered-NdFeB production yet, most Indian supply is imported and assembled — so the practical choice for commercial volume is the supplier, not the country. Mainrich competes on the full grade range (N30-N58 through AH), GBD that cuts Dy/Tb cost 30-50%, finished assemblies built to drawing, IATF 16949 quality, and in-house export licensing. As India's own production scales later this decade, Mainrich is the qualified commercial source and second source in the meantime.
Frequently Asked Questions
Are there neodymium (NdFeB) magnet manufacturers in India?
+
Not at commercial scale yet. India's domestic NdFeB production is pilot-stage — ARCI runs an end-to-end NdFeB pilot line, and IREL makes samarium-cobalt (not NdFeB) at kilogram scale. Larger commercial production (Midwest Advanced Materials, and the government's ₹7,280-crore sintered-magnet scheme) is under construction or out for bids. Most established Indian magnet companies make AlNiCo, ferrite, or assemblies, or build separation equipment, importing the NdFeB they use. About 93% of India's permanent-magnet imports come from China.
Is it cheaper to buy magnets in India or to import them?
+
For finished sintered NdFeB, India imports either way — domestic players largely re-sell or assemble imported material, so 'buying in India' usually means buying an imported magnet with a local margin added. For commercial volume, a factory-direct international supplier is typically the most cost-effective route. The largest single cost lever on high-temperature grades is the heavy-rare-earth content, which GBD can cut 30-50% while holding coercivity.
Does India restrict Chinese-made magnets?
+
For civilian and industrial use, no — Chinese NdFeB imports remain legal and dominant, and India has even extended permission to import rare-earth-magnet traction-motor sub-assemblies because domestic supply cannot yet meet EV demand. Restrictions are defense-specific (indigenization lists and limits on Chinese components in some military procurement), not a blanket civilian ban. Confirm requirements for defense end-use.
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 30-50% less Dy/Tb. Because those heavy rare earths are the most expensive, supply-constrained inputs, GBD directly lowers cost.
