- ALMM List-III covers solar wafers and ingots — one step up from cells.
- It is planned for around 1 June 2028 (status: planned, not live — verify against the latest MNRE order).
- It builds on List-I (modules) and List-II (cells) to push domestic content deeper.
- It mainly affects government-linked, subsidy and many tender projects, the same scope as ALMM today.
- Start now: ask suppliers about wafer sourcing and avoid contracts that assume imported wafers stay compliant.
You have just got used to checking modules and cells. Now MNRE wants to add a third list — for the wafers and ingots inside those cells. ALMM List-III is the next rung on the domestic-content ladder, planned for around 1 June 2028. It is not live yet, and the date can move, but the direction is clear: the rule keeps moving up the supply chain.
What is ALMM List-III?
ALMM List-III is the planned approved list for solar wafers and ingots, set by MNRE. It is the third list in the ALMM family. List-I approves finished modules. List-II approves the cells inside them. List-III would approve the wafers and ingots inside those cells. The goal is the same each time — make sure the part is built in India by an enlisted maker.
A wafer is the thin slice of silicon a solar cell is built on. An ingot is the silicon block that wafers are cut from. Today most cells use imported wafers, often from a small number of overseas suppliers. List-III aims to change that by 2028. Status as of 20 June 2026: planned, not live. Verify against the current MNRE order before you act on it.
When does ALMM List-III start?
ALMM List-III is planned to take effect around 1 June 2028, but treat that as a target, not a settled fact. MNRE has moved ALMM timelines before. Some reports tie List-III to a trigger such as a level of Indian wafer capacity coming online (for example a 15 GW or three-unit threshold has been discussed) rather than a fixed calendar date.
Why the date is not locked
The List-II cell mandate — planned for around 1 June 2026 — faced deferment requests and court proceedings. That shows how these dates can shift. List-III sits two years further out, so it has even more room to move. Confirm whether the 1 June 2028 date and any capacity trigger still stand against the latest MNRE order before you plan around them. Our deadlines calendar tracks every date in one place.
How does List-III fit the List I-II-III ladder?
List-III is the top rung of a three-step ladder, each step reaching one part deeper into the module. Read the ladder from the finished panel down to the raw silicon, and the logic is easy to see.

For a deeper walk-through of how the three lists stack, see our ALMM ladder explainer. The short version: by 2028 a fully compliant module may need an enlisted module, an enlisted cell, and an enlisted wafer all at once.
Why is MNRE adding wafers and ingots?
MNRE is adding List-III to build a full domestic solar supply chain inside India. Today India makes a lot of modules and a growing number of cells, but most wafers still come from abroad. The government wants the value — and the jobs — to stay in the country, from raw silicon up to the finished panel.
There is also a supply-security reason. A solar industry that depends on imported wafers can be squeezed if those imports get scarce or costly. By approving Indian wafers and ingots, MNRE wants to reduce that risk. List-III is the policy tool that pushes wafer factories to get built and enlisted.
Who does ALMM List-III affect?
ALMM List-III affects the same projects ALMM already covers — mainly government-linked, subsidy and many tender jobs — not every private project. If your work needs ALMM today, plan for a wafer check from 2028. If you only do non-ALMM private C&I, the impact is smaller, but the market shifts around you.
EPCs and procurement leads
The people most affected are EPC owners and procurement leads who sign multi-year supply contracts now. A deal signed in 2026 for delivery in 2028 could run straight into List-III. If that deal assumes imported wafers, the module may stop being compliant mid-contract.
Module makers and importers
Module makers will need enlisted wafers in their cells. Importers of cells or modules face a tighter rule. This flows down to you as the buyer: your supplier list and your prices can both shift. The cell-supply squeeze you may already see — covered in our TOPCon cell shortage guide — is a preview of how a deeper rule can tighten supply.
What is the wafer-to-cell-to-module chain?
The wafer-to-module chain is the path from raw silicon to a finished solar panel, and List-III targets the very start of it. Understanding the chain helps you see exactly where List-III bites.
- Polysilicon — purified silicon, the raw material.
- Ingot — silicon melted and grown into a solid block. (List-III)
- Wafer — the ingot sliced into thin square sheets. (List-III)
- Cell — a wafer turned into a working solar cell. (List-II)
- Module — cells wired and sealed into a panel. (List-I)
Each ALMM list locks one of these steps to an enlisted Indian maker. List-III reaches the furthest down, to ingots and wafers. By 2028 the whole lower chain could need to be domestic for an ALMM-and-DCR project.
Can Indian factories supply List-III wafers by 2028?
Indian wafer and ingot capacity is rising but was small next to module capacity as of mid-2026. Many big plants were announced but still under construction. Whether supply meets demand by the List-III date depends on factories that are not finished yet.
This is why the date may be tied to a capacity trigger. If MNRE waits until enough Indian wafer capacity is live, it avoids a rule that no factory can meet. Do not treat any capacity figure or manufacturer name as fixed — these are point-in-time and must be verified on the MNRE portal. Our companion guide on future-proofing procurement covers how to write contracts around this uncertainty.
What exemptions should you watch for?
ALMM rules often carve out non-government projects, and List-III is likely to follow that pattern. Open-access and pure private C&I work may sit outside the strict mandate, at least at first. But the exact carve-outs are set by MNRE and can change, so do not assume an exemption holds.
An open-access or wheeling project may use a wider supplier pool than a subsidy job. Read our open-access and wheeling rules for how that line is drawn today. Confirm the open-access wafer-exemption window against the latest MNRE order — the planned window runs to the List-III start, but verify.
How should EPCs prepare for List-III now?
Preparing for List-III now is mostly about contracts and visibility, not panic buying. The rule is two years out, so you have time — if you start tracking it today.
- Track the date. Re-check the List-III effective date and any capacity trigger every quarter against MNRE.
- Ask suppliers about wafers. For any 2027-2028 delivery, ask where the wafers and ingots come from.
- Avoid locked-in imports. Do not sign long deals that assume imported wafers stay compliant past 2028.
- Add compliance clauses. Make the supplier responsible if a part is delisted — see our contract-clause guide.
- Keep a source trail. Record the wafer and cell origin on every BOM so you can prove the chain later.
The EPCs that lose money on rule changes are the ones who find out late. Build the habit of recording the supply chain on every order now, and a 2028 wafer rule becomes a checkbox, not a crisis. Our guide on proving the cell chain of custody shows the paper trail that List-III will extend.
How SuryaHub helps you stay ready for List-III
A wafer rule only hurts if you cannot see your own supply chain. SuryaHub holds the ALMM status and source data on every line of your procurement and inventory records, so you can answer "where did this wafer come from?" before a rule forces the question. It links each BOM to the job it feeds, so a future List-III check does not catch a project mid-build. SuryaHub is pre-revenue; the only real pilots are Suryantra Energy and RGESPL, and every date or figure here is a scheme fact to verify, not a guarantee.

Frequently asked questions
What is ALMM List-III?+
ALMM List-III is the planned approved list for solar wafers and ingots, set by MNRE. It extends the ALMM ladder one step further up the supply chain. List-III would require the wafers and ingots inside an enlisted cell to come from an enlisted Indian maker. Verify its status against the current MNRE order.
When does ALMM List-III start?+
ALMM List-III is planned to take effect around 1 June 2028, but this date is not settled and can move. MNRE has revised ALMM timelines before, and the wafer mandate is still being shaped. Confirm the effective date and any trigger conditions against the latest MNRE order before you rely on it.
How is ALMM List-III different from List-I and List-II?+
ALMM List-I covers finished modules, List-II covers the cells inside them, and List-III covers the wafers and ingots inside the cells. Each list pushes the domestic-content rule one step further up the supply chain, so a compliant module in 2028 may need an enlisted module, enlisted cell, and enlisted wafer.
Does ALMM List-III apply to every solar project?+
ALMM List-III is expected to apply where ALMM already applies, mainly government-linked, subsidy and many tender projects, not all private C&I jobs. The exact scope and any open-access exemption window are set by MNRE and can change. Confirm whether your project type is covered against the current MNRE order.
Can Indian factories supply ALMM List-III wafers by 2028?+
Indian wafer and ingot capacity is growing but was small compared with module capacity as of mid-2026. Whether supply meets demand by the List-III date depends on factories that are still being built. Treat any capacity figure as point-in-time and verify named manufacturers on the MNRE portal before you plan around them.
How should EPCs prepare for ALMM List-III now?+
EPCs should track the List-III date, ask suppliers about wafer and ingot sourcing in 2026 to 2028 contracts, and avoid signing long-term deals that assume imported wafers stay compliant. SuryaHub can hold ALMM status and source data on every BOM line so a future wafer rule does not catch a project mid-build.
