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.
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:
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. Confirm the quality-system and submission requirements specified by your customer. Verify the current certificate, covered activities and named production plant with the issuer. The contracting supplier and certified production entity can differ; document their responsibilities and the production route.
Magnet cost and GBD. Grain boundary diffusion is evaluated against the required coercivity, material composition and magnet geometry. In a reported N45H specimen comparison, Hcj changed from 17.67 to 26.55 kOe and Br from 13.62 to 13.61 kGs. A new programme needs its own material validation and cost comparison; this specimen result does not establish a saving for another part.
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. A qualified second source can reduce dependence on one production route. Compare capacity, qualification work, material origin and delivery constraints for each route. Export approval and transit timing remain specific to the shipment.
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.

Shortlisting suppliers for a Indian program?
Send a drawing or a target spec and we'll quote the right grade or assembly, flagging any end-use restriction up front.
5.Midwest Advanced Materials
Hyderabad, India
India's flagship private sintered-NdFeB build-out, planning ~500 t/yr scaling toward ~5,000 t/yr; under construction, not yet at commercial scale.
6.Dura Magnets
Est. 1981 · Satara, India
Cast AlNiCo, SmCo, and rare-earth (NdFeB) magnets in bulk; NdFeB is likely machined from imported blanks rather than sintered in-house.
7.Star Trace
Est. 1983 · Chennai, India
Primarily a magnetic-separation and process-equipment manufacturer that also supplies AlNiCo/ferrite/SmCo/NdFeB magnets (consumes bought-in magnets).
8.Kumar Magnet Industries
Est. 1986 · Ahmedabad, India
Magnetic-separation equipment maker (drums, lifters, separators) that supplies NdFeB for those uses; not a sintered-NdFeB producer.
Reviewing a second source?
Mainrich reviews the drawing, production route and shipment documentation for the proposed order. Qualification and delivery timing are agreed with your team.
9.J R Strong Magnet
Est. 2008 · Pune, India
Trader and distributor of NdFeB, ferrite, and soft magnets, largely imported (Chinese-origin) sintered NdFeB resold across India.
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 Indian 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 Indian 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.

FAQ · Questions
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?
Compare quotations for the same drawing, material, quantity and inspection requirements. Include tooling, qualification, freight, duties and delivery terms. The supplier location or use of grain boundary diffusion alone does not establish the lower delivered cost.
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?
Confirm the quality-system and submission requirements specified by your customer. Verify the current certificate, covered activities and named production plant with the issuer. The contracting supplier and certified production entity can differ; document their responsibilities and the production route.
How can GBD affect magnet cost?
Grain boundary diffusion is evaluated against the required coercivity, material composition and magnet geometry. In a reported N45H specimen comparison, Hcj changed from 17.67 to 26.55 kOe and Br from 13.62 to 13.61 kGs. A new programme needs its own material validation and cost comparison; this specimen result does not establish a saving for another part.
