What project owners need to know.
ALMM, DCR and BIS answer three different questions. ALMM, run by MNRE, asks whether a manufacturer and model are enlisted: List-I covers modules, List-II covers cells and List-III is announced for ingots and wafers from 1 June 2028. DCR asks whether a module in certain government-supported schemes is made in India with Indian cells. BIS certification asks whether a product meets an Indian Standard; under MNRE's Goods Order it covers modules, inverters and batteries, not ingots or wafers. For a wafer buyer today, ALMM List-III is the regime to plan for, and wafer quality is still set in the purchase specification.
The one-table comparison
Status as of 25 October 2026. Each line links back to the primary documents listed in the sources.
- ALMM: MNRE enlistment of manufacturers and models. List-I modules; List-II cells (in force from 1 June 2026 for covered project categories); List-III ingots and wafers, announced for 1 June 2028. Binds covered projects and, through them, their supply chain.
- DCR: a provenance condition in certain government-supported schemes, under which modules must be made in India using Indian cells, verified through NISE's DCR portal. Historically stops at the cell.
- BIS: certification against Indian Standards under MNRE's Solar Systems, Devices and Components Goods Order, 2025 (amended by S.O. 3706(E) in July 2026). Covers modules, inverters and storage batteries; no order covers cells, wafers or ingots as of this date.
ALMM List-III and the ingot-wafer step
MNRE's 17 March 2026 amendment and PIB's 18 March release set 1 June 2028 as the List-III effective date. The initial wafer list is to be issued only once at least three independent units with combined capacity of at least 15 GW are operational, and a wafer applicant must hold equivalent ingot capacity.
For a buyer, that means the wafer's ALMM status will depend on the supplier's ingot capacity as well as its wafer line. Ask for both.
DCR vs ALMM: scheme rule vs supply-chain list
DCR is attached to the scheme that funds a project, such as rooftop or agricultural solar programmes, and asks for Indian modules made with Indian cells. ALMM is attached to the manufacturer and model and applies across covered project categories. A temporary List-II relief window for selected net-metering and open-access projects commissioning by 31 December 2026, announced by PIB in July 2026, is an ALMM measure, not a DCR relaxation.
The direction of travel is the same for both: the domestic-content boundary is moving upstream from module to cell and, from 2028, toward wafer and ingot.
The BIS gap at ingot and wafer level
BIS certification is about product quality against a standard, not about where the product is made. MNRE's Goods Order brings modules, inverters and batteries under compulsory BIS certification; we found no BIS standard or quality control order for solar wafers or ingots as of October 2026.
In practice, wafer quality is fixed in the purchase specification, usually referencing SEMI PV22 and related test methods for dimensions, resistivity, lifetime and defects. ALMM List-III, when it starts, is an enlistment of manufacturers rather than a quality standard, so the specification stays the buyer's main quality tool.
Buyer checklist
Use this list to separate the three questions when evaluating an ingot or wafer supplier.
- Origin: where is the ingot grown and the wafer sliced, and can that be documented lot by lot?
- ALMM readiness: is the supplier planning List-III enlistment, and does it hold equivalent ingot capacity?
- Downstream use: will the wafers go into cells for ALMM List-II or DCR projects, and what origin evidence will the cell maker need?
- Quality: which specification and test methods govern acceptance, and who tests?
- Status check: read the latest MNRE ALMM page and notices before signing, not a headline
How JRST supports this requirement
JRST helps ingot and wafer projects map compliance into the plant plan: ingot-wafer integration for List-III, origin documentation, specifications and qualification.

What is the difference between ALMM and DCR?
ALMM is MNRE's list of approved manufacturers and models, applying across covered project categories, with List-I for modules, List-II for cells and List-III announced for ingots and wafers. DCR is a condition in certain government-supported schemes requiring modules made in India with Indian cells. ALMM attaches to the supplier; DCR attaches to the scheme.
Is BIS certification required for solar wafers in India?
Not as of October 2026, as far as we could find. MNRE's Goods Order requires BIS certification for PV modules, inverters and storage batteries; wafers and ingots are not on its product list. Check BIS and MNRE notifications for later orders.
Which compliance matters most for an ingot or wafer buyer?
ALMM List-III, effective 1 June 2028, is the regime that reaches ingots and wafers directly. Until then, the downstream rules buyers serve, ALMM List-II and DCR for cells and modules, shape what origin evidence a wafer supplier should be able to provide.
Does ALMM List-III set wafer quality standards?
No. It is an enlistment of manufacturers and models with capacity and ingot-integration conditions. Wafer quality is still defined in the purchase specification, usually against SEMI test methods.
