Why the Difference Between a Sintered Block and a Saleable Magnet Matters
India’s REPM scheme is intended to create 6,000 MTPA of integrated domestic manufacturing capacity. The policy intent is clear: move India from complete import dependence towards domestic production of sintered NdFeB magnets, a strategic input for electric vehicles, wind turbines, electronics, aerospace, defence and advanced industrial applications.
But a less glamorous question sits underneath this ambition: what exactly is being counted, subsidised and incentivised?
Is the scheme supporting the production of sintered magnet blocks? Is it supporting fully finished, coated, magnetised and customer-saleable magnets? Is capacity measured before finishing losses or after them? Are downstream assets such as machining, coating and magnetisation unambiguously part of the eligible manufacturing chain? How will rejects, scrap, reprocessing and saleable output be treated?
These may sound like technical questions. They are not. They go directly to the commercial meaning of the scheme.
In a complex materials industry, a tonne of nominal capacity is not the same as a tonne of qualified product. A tonne of sintered output is not necessarily a tonne of finished magnets. A tonne of manufactured material is not automatically a tonne that customers will buy.
If the policy objective is self-reliance in rare earth permanent magnets, the scheme must be judged at the point where India produces magnets that are finished, reliable, qualified and saleable. Anything short of that risks counting industrial progress before it has become commercially meaningful.
The Scheme says “Finished Magnets”, but the Production Boundary still needs Sharper Articulation
The Cabinet approval described the scheme as supporting integrated REPM manufacturing facilities involving conversion of rare earth oxides to metals, metals to alloys and alloys to finished REPMs. That phrase is important. It suggests that the policy objective is not merely to create intermediate materials or semi-processed magnet blocks, but to reach the stage of finished magnets.
The scheme notification and RFP also require integrated sintered NdFeB REPM manufacturing and insist that intermediate processes must be undertaken at the project for incentive eligibility. This is a sensible safeguard. Without such a requirement, a beneficiary could import semi-finished material, carry out limited processing and claim the appearance of domestic manufacturing.
However, the RFP’s technical descriptions place more explicit emphasis on oxide-to-metal conversion, alloy preparation and powder production, magnet fabrication and sintering, and testing and characterisation. These are central stages of magnet manufacturing, but they do not, by themselves, exhaust the commercial journey from alloy to application-ready magnet.
After sintering, the product may still require cutting, grinding, machining, chamfering, cleaning, surface treatment, coating, magnetisation, final inspection, packing and application-specific quality checks.
These are not decorative downstream activities. They can determine whether the product is saleable.
The ambiguity is not that the scheme necessarily excludes these activities. The eligible-investment language appears broad enough to cover manufacturing-related plant, machinery, equipment, utilities, R&D and technology-transfer expenditure. The problem is that the scheme could have stated the terminal production boundary more explicitly.
A strategically important scheme should not leave bidders, evaluators, lenders and future auditors to infer whether “finished REPMs” means sintered material capable of further conversion or application-ready magnets suitable for customer shipment.
A Sintered Magnet Block is not the Customer’s Product
The distinction matters because many customers do not buy magnet-making potential. They buy magnets in defined shapes, dimensions, coatings, grades and performance characteristics.
A motor manufacturer may require arc-shaped segments with tight tolerances and specific coating. An automotive supplier may require small precision components with strict traceability. A defence or aerospace application may require magnets validated for demanding thermal, corrosion and reliability conditions. A wind or industrial application may require larger magnets meeting defined stability and durability requirements.
In such cases, the customer is not purchasing the abstract achievement of oxide-to-magnet integration. It is purchasing a component that must fit inside a product and perform predictably.
A sintered block is therefore not the end of the commercial process. It is an intermediate achievement on the way to the customer’s actual requirement.
The downstream steps can materially affect:
- Dimensional accuracy;
- Surface quality;
- Coating adhesion;
- Corrosion resistance;
- Mechanical integrity;
- Magnetic performance after magnetization;
- Product rejection levels;
- Recoverable scrap;
- Delivery reliability; and
- Final cost per saleable kilogram.
The policy question should therefore be simple: is the subsidised capacity defined at the point where the product becomes a customer-usable magnet?
If not, the headline capacity number may overstate the commercially relevant capacity.
Finishing Losses are not Accounting Trivia
Sintered NdFeB magnet manufacturing can involve material losses and rejections at multiple stages. These may arise during alloy preparation, powder handling, pressing, sintering, heat treatment, cutting, grinding, machining, coating, magnetisation and final inspection.
Some material may be internally recycled. Some may become sludge or scrap requiring recovery. Some may be technically recoverable but commercially costly to reprocess. Some may simply represent process inefficiency during the early years of plant stabilisation.
For project economics, this matters enormously.
If a plant is described as having 600 MTPA capacity, the investor, lender, Government and market must understand what that figure represents:
- Gross sintered output;
- Output before machining;
- Output after machining;
- Output after coating;
- Magnetised finished goods;
- Saleable approved product; or
- Eligible invoiced sales.
These are not the same number.
If capacity is measured before finishing losses, then the actual saleable output may be lower. If incentives are linked to eligible sales, then the beneficiary receives support only on what is sold. But capital subsidy and capacity certification may still be influenced by how the commissioned facility is measured.
A scheme designed to create strategic industrial capability should therefore define capacity in relation to final saleable production, not merely upstream process throughput.
Otherwise, the policy could end up celebrating commissioned capacity that produces fewer customer-ready magnets than the headline figure suggests.
Eligible Investment should Follow the Commercial Production Chain
Capital subsidy is payable at 15% of eligible investment, subject to capacity-linked caps. The notified scheme provides ₹750 crore for capital subsidy within the overall ₹7,280 crore outlay.
Eligible investment therefore becomes a critical issue. If downstream operations are necessary to produce customer-saleable magnets, the related assets should be unambiguously eligible.
This includes equipment for:
- Precision cutting;
- Grinding and machining;
- Surface preparation;
- Coating;
- Coating inspection;
- Magnetisation;
- Final testing;
- Quality laboratories;
- Scrap recovery;
- Environmental management; and
- Packing for sensitive products.
If such assets are not clearly treated as part of the integrated manufacturing facility, the scheme may incentivise an incomplete production boundary. Beneficiaries may invest heavily up to sintering and underinvest in the less celebrated but commercially indispensable finishing chain.
That would be a curious outcome: India would subsidise the making of magnets and then leave the final conversion into customer-usable form as an implementation footnote.
The better interpretation is that these assets should be eligible where they are required for saleable REPM production. But good scheme design should not depend on benevolent interpretation. It should say so clearly.
Domestic Value Addition must be Traceable
The RFP’s requirement that intermediate processes be undertaken at the project is intended to ensure genuine domestic manufacturing. This is important because REPM manufacturing offers room for definitional games.
A beneficiary could, in theory, create the appearance of domestic production by importing material at an intermediate stage and performing limited downstream operations. Conversely, a legitimate integrated producer could be penalised if the documentation framework does not properly capture internal recycling, reprocessing and intermediate material flows.
The scheme therefore needs strong traceability across:
- Raw material receipts;
- Oxide conversion;
- Metal production;
- Alloy production;
- Powder production;
- Pressing and sintering;
- Machining;
- Coating;
- Magnetization;
- Rejects;
- Internal scrap;
- Reprocessing;
- Finished goods; and
- Eligible sales.
This is not only an audit issue. It affects the credibility of the self-reliance claim.
If India’s objective is to move beyond dependence on imported magnets, it must know how much of the value chain is actually being performed domestically. The country should not discover later that “domestic magnet production” includes too much imported intermediate content and too little domestic process capability.
The Headline Outlay may be Larger than the likely Payout
The Government has announced an overall financial outlay of ₹7,280 crore for the scheme. This comprises ₹750 crore of capital subsidy, ₹6,450 crore of sales-linked incentives and ₹80 crore of administrative expenditure. The objective is to establish 6,000 MTPA of integrated REPM manufacturing capacity.
The number is large enough to signal seriousness. But it should not be mistaken for guaranteed expenditure.
The sales-linked incentive is not a simple grant handed out upon project approval. It depends on actual eligible sales, the beneficiary’s quoted incentive rate, the turnover cap, capacity-linked cumulative limits, commissioning conditions and claim procedures. If bidders quote lower than the ceiling, the payable incentive reduces. If plants commission late, sales are delayed. If customer qualification takes longer than expected, eligible sales lag. If utilisation remains low, incentive claims remain low.
The scheme can therefore announce a large support envelope while ultimately disbursing materially less.
Again, this is not inherently improper. Public schemes routinely operate with sanctioned outlays that represent maximum exposure. The issue is presentation and understanding.
For industrial-policy evaluation, the relevant questions are:
- What is the maximum budgetary exposure?
- What is the expected disbursement under realistic scenarios?
- What amount is likely to be paid if commissioning is delayed?
- What happens if customer approval takes three to four years?
- How much support reaches beneficiaries during the most difficult ramp-up years?
- How much remains unclaimed because sales do not materialise?
A headline outlay creates political clarity. It does not by itself reveal the economic support that the industry will actually receive.
Competitive Bidding may make the Scheme look Generous and Spend Frugally
The RFP caps the quoted sales incentive at ₹2,150 per kilogram and ranks technically qualified bidders by the lowest incentive sought. This structure is fiscally attractive for the Government. Bidders compete by reducing the support they request.
If five aggressive bidders quote well below the ceiling, the Government can allocate capacity while preserving a substantial part of the apparent incentive envelope. If the plants then face slow qualification or weak sales, actual outgo reduces further.
This may be good for the exchequer. It may not be good for industrial resilience.
A bidder trying to win may underquote the sales incentive on the assumption that capital subsidy, raw-material access, first-mover advantage and future market growth will compensate. But if finishing losses, low yields, delayed approvals and price pressure are worse than expected, the quoted incentive may be insufficient.
The scheme then has a familiar public-policy defence: the bidder chose its own number.
That defence may protect the Government contractually. It does not protect the national objective if the selected beneficiaries become financially weak or commercially hesitant during the sector’s formative years.
A strategic industry cannot be built only by discovering who is willing to accept the least support. It must also examine whether the support being accepted is enough for the task being attempted.
Capacity without Commercial Definition Creates Measurement Risk
Every industrial scheme eventually needs success indicators. For REPMs, the obvious indicators will be investment made, capacity commissioned, production achieved, sales made and incentives disbursed.
But these are not sufficient unless the units are defined carefully.
The Government should not merely report “capacity created” without explaining whether the capacity relates to:
- Oxide conversion;
- Alloy production;
- Sintered magnet output;
- Finished magnet production; or
- Customer-approved saleable magnets.
Similarly, production numbers should distinguish between gross production and saleable output. Sales should distinguish between early trial sales, commercial repeat orders and sales into demanding qualified applications.
Otherwise, the scheme may generate flattering numbers that do not correspond to strategic capability.
A plant may produce volume in simpler grades or less demanding shapes while remaining unable to serve high-performance applications. Another may produce smaller volumes but qualify for more strategic use cases. A pure tonnage metric may fail to capture this difference.
For a scheme justified in the language of self-reliance, the quality and usability of capacity matters as much as the quantity.

The Scheme needs a Clearer Outcome Hierarchy
A more disciplined policy framework would distinguish five levels of success:
- Investment success: the beneficiary spends the required capital.
- Physical success: the plant is commissioned.
- Process success: the plant produces magnets with stable yields and quality.
- Commercial success: customers buy repeat volumes.
- Strategic success: Indian industry relies on domestic magnets for critical applications.
The tender and scheme architecture appear strongest at the first two levels and partially at the fourth, through sales-linked incentives. The third and fifth levels require more explicit treatment.
Process success depends on yield, rejection, rework, scrap recovery, finishing, coating reliability and consistency. Strategic success depends on the use of domestic magnets in applications that matter to India’s industrial and security priorities.
If these are not tracked, the scheme may treat a commissioned facility and some eligible sales as sufficient evidence of success.
That would be administratively convenient and strategically incomplete.
The Real Test is the Saleable Kilogram
India’s REPM scheme is a necessary intervention in a critical sector. But the phrase “6,000 MTPA capacity” will mean little unless it translates into finished, qualified and saleable magnets.
This is why the manufacturing boundary matters. This is why finishing assets matter. This is why process losses matter. This is why capacity certification matters. This is why actual disbursement may tell a very different story from headline outlay.
A policy that seeks to create self-reliance cannot be satisfied with nominal process capacity. It must care about the saleable kilogram.
The saleable kilogram is the kilogram that has passed through the required process chain, survived finishing losses, met grade specifications, obtained customer acceptance, entered a real application and generated a repeat commercial relationship.
That is the kilogram India needs.
The rest may still be useful industrial learning. But it should not be confused with the strategic outcome promised by the scheme.
The danger is not that the Government has failed to recognise the importance of integrated manufacturing. It clearly has. The danger is that the implementation framework may still leave too much room for ambiguity between installed capacity, intermediate output and customer-ready magnets.
In a conventional subsidy scheme, such ambiguity would be a technical defect.
In a strategic materials scheme, it could become the difference between an impressive announcement and a usable domestic industry.
