Import Duty on Solar Modules in India 2026: BCD, ALMM, and What EPCs Pay

Ask ten Indian EPC owners what the import duty on solar modules is and at least seven will say "40 percent." That answer was correct from April 2022 until the Union Budget 2025-26 changed the structure in February 2025. The headline Basic Customs Duty (BCD) rate dropped to 20 percent, but a 20 percent Agriculture Infrastructure and Development Cess (AIDC) was added on top, so the real protection for domestic manufacturers barely moved.

For an EPC (Engineering, Procurement, and Construction) business, the number that matters is not the BCD rate in a news headline. It is the full landed cost per watt-peak (Wp) after BCD, AIDC, Social Welfare Surcharge (SWS), and Integrated GST (IGST), and whether an imported module is even allowed on the project you are quoting. This guide gives you the current 2026 duty stack, worked rupee math on a 550 Wp module, the ALMM rules that decide which projects can use imports at all, and what to write into your quotes so duty changes do not eat your margin.

What import duty does an EPC actually pay in 2026?

An Indian EPC importing solar modules in 2026 pays four charges stacked on the CIF (Cost, Insurance, Freight) value: 20 percent BCD, 20 percent AIDC, SWS at 10 percent of the combined BCD and AIDC (which works out to about 4 percent of CIF), and 12 percent IGST calculated on the duty-paid value. The IGST portion is creditable against your output GST, so it is a cash-flow cost, not a margin cost.

Solar cells imported for module assembly inside India pay 20 percent BCD plus 7.5 percent AIDC plus SWS of about 2.75 percent, under the same tariff heading 8541. This lower stack for cells is deliberate: the government wants value addition to happen inside India, so assembling modules from imported cells is cheaper than importing finished modules.

These rates come from the Union Budget 2025-26 presented on 1 February 2025, which revised the earlier 40 percent and 25 percent BCD structure that had been in force since 1 April 2022, as reported by Energetica India and TaiyangNews in February 2025. The notification framework sits with the Central Board of Indirect Taxes and Customs, and you can verify current entries on cbic.gov.in.

How the duty moved from 40 percent to the Budget 2025 stack

India's solar import duty story has three chapters, and knowing them helps you predict the next change.

Chapter 1, the safeguard era (2018 to 2021). India levied a safeguard duty on imported cells and modules, starting at 25 percent and tapering down, aimed mainly at Chinese and Malaysian imports. When it expired in July 2021, the government announced its replacement well in advance.

Chapter 2, the 40/25 era (April 2022 to January 2025). From 1 April 2022, BCD of 40 percent applied to solar modules and 25 percent to solar cells, with no AIDC. The goal was to push procurement toward domestic factories backed by the Production Linked Incentive (PLI) scheme. Prices of imported modules effectively jumped about 50 percent overnight once SWS and IGST compounded, and large tenders that had assumed imported supply had to be repriced.

Chapter 3, the Budget 2025-26 restructure (February 2025 onward). The Finance Minister cut headline BCD to 20 percent on both cells and modules but layered AIDC on top: 20 percent on modules, 7.5 percent on cells. SWS applies at 10 percent of the combined BCD plus AIDC. The net protection on modules stayed near 44 percent of CIF, while the cell stack fell to about 30 percent, widening the incentive to assemble modules in India from imported cells, per Energetica India, February 2025.

The full duty stack on a 550 Wp module, with worked math

Here is the complete duty stack as it applies to an imported 550 Wp module in 2026, with a worked example. The example uses an illustrative CIF price of USD 0.11 per Wp (about ₹9.7 per Wp at ₹88 per dollar), which is a representative Chinese export price for Tier-1 modules in mid-2026, not a quote from any supplier.

Two things in this table deserve attention. First, the non-creditable stack (BCD plus AIDC plus SWS) adds about 44 percent to the CIF value, nearly identical to the old 40 percent BCD era once SWS compounds. Second, the IGST line looks large but comes back as input tax credit, which is why the GST treatment of imported and domestic modules converges after credit. For the domestic side of GST, including the 12 percent slab on modules and the 70:30 composite supply rule, read our guides on GST on solar systems in India and the GST rate on solar panels. Module classification under HSN 8541 is covered in HSN codes for solar panels.

The Landed Cost Stack: a 5-layer framework for import decisions

Every import-versus-domestic decision in your EPC should run through what we call The Landed Cost Stack: five layers, in fixed order, that convert a supplier's dollar quote into a per-watt decision. Skip a layer and you either overpay or quote a project you cannot legally build.

1. 1

   Layer 1: CIF price in ₹/Wp

   Convert the supplier quote to rupees at your bank's forward rate, add freight and insurance to an Indian port, and divide by nameplate wattage. Everything else stacks on this number.

2. 2

   Layer 2: Non-creditable duties (BCD + AIDC)

   Add 40 percent of CIF for modules (20% BCD + 20% AIDC) or 27.5 percent for cells. This money never comes back.

3. 3

   Layer 3: SWS on the duty, not the goods

   Add 10 percent of the Layer 2 amount, about 4 percent of CIF on modules. Small, but it compounds into the IGST base in the next layer.

4. 4

   Layer 4: IGST cash-flow cost

   Add 12 percent on the duty-paid value. It returns as input tax credit, but you fund it for 30 to 90 days, so price the working capital, not just the tax.

5. 5

   Layer 5: The ALMM compliance gate

   Ask one question: does this project require ALMM-listed modules? If yes (any subsidised rooftop, government tender, or PM Surya Ghar job), the import option closes regardless of price, and you restart the stack with domestic quotes.

Run a domestic quote through the same stack with zeros in Layers 2 to 4, and the comparison becomes honest. Most EPCs we speak with find the imported option wins only for large open-access or captive projects above roughly 5 MW, where the compliance gate is open and container-scale freight compresses Layer 1.

ALMM: the real barrier to imported modules

The Approved List of Models and Manufacturers (ALMM), maintained by the Ministry of New and Renewable Energy (MNRE), is a bigger barrier to imported modules than any duty rate. For any project that touches government subsidy or a government-linked tender, modules must come from ALMM List-I manufacturers, and the list contains almost exclusively Indian factories, as explained on mnre.gov.in.

Three ALMM facts matter for your 2026 pipeline:

• PM Surya Ghar Muft Bijli Yojana requires ALMM-listed modules. Rooftop systems claiming the central financial assistance (CFA) of up to ₹78,000 must use ALMM List-I modules, per the PM Surya Ghar National Portal. In practice that means domestic modules with Domestic Content Requirement (DCR) compliance for the subsidised segment.
• ALMM List-II for cells took effect in June 2026. From 1 June 2026, ALMM-listed modules must also use cells from ALMM List-II manufacturers, closing the "imported cell, Indian laminate" route for subsidised projects. Approved cell capacity under List-II has already crossed 31.76 GW, according to MNRE's updated list reported by Mercom India, July 2026.
• Duty savings cannot buy compliance. An imported module at ₹14.0/Wp landed still cannot go on a subsidised 3 kW rooftop in Surat. The compliance gate is binary, so check it first, not last.

We have a full explainer on list mechanics, DCR rules, and verification steps in ALMM list explained, and the ALMM glossary entry covers the terminology your sales team should use with customers.

DCR vs non-DCR: which module for which project

DCR (Domestic Content Requirement) modules are made in India from Indian cells; non-DCR modules are made in India from imported cells or imported fully. Both can appear on ALMM List-I, but subsidised rooftop projects under PM Surya Ghar effectively demand DCR-grade supply after the List-II cell rule. Open-market projects (captive, open access, private C&I) can use anything that clears customs and BIS certification.

Domestic module prices in 2026: where the market sits

Because ALMM channels most EPC demand toward domestic supply, domestic prices are the numbers that actually hit your BOM (Bill of Materials). The trend through mid-2026 has been stable to slightly soft, after the volatile 2022 to 2024 swings.

The takeaway from these numbers: the price gap between an imported module at roughly ₹14.0/Wp landed and a domestic non-DCR module at ₹13.8 to 14.2/Wp has essentially closed in 2026. The duty stack did its job. Where a real gap persists is DCR modules for subsidised work, which trade at a ₹1 to 3/Wp premium over non-DCR because List-II cell supply is still ramping. For the full price history and per-watt breakdowns, see solar panel price trends and JMK Research for monthly updates.

What to put in your quotes to protect your margin

Duty structures have changed twice in four years, and ALMM rules have tightened twice since 2024. If your customer quotes freeze prices for 60 or 90 days without protection clauses, a single notification can erase a project's margin. Five clauses belong in every solar quotation you send in 2026:

1. Price-validity window of 15 to 30 days. Module prices move weekly; state the validity date on the first page, not in fine print.
2. Duty and tax change pass-through. One line stating that any change in BCD, AIDC, SWS, GST rates, or ALMM-driven supply constraints after the quote date is passed through at actuals.
3. Module make and model named, with substitution rights. Name the DCR module you priced, and reserve the right to substitute an equivalent ALMM-listed model at a revised price if supply tightens.
4. DCR vs non-DCR stated explicitly. Write "DCR ALMM-listed modules" on PM Surya Ghar quotes so there is no dispute at inspection time.
5. GST split shown transparently. Show the 12 percent module GST and the composite-supply treatment separately; customers trust quotes that itemise tax.

Our guide on what to include in a solar quote covers the full quotation anatomy, and solar business pricing strategy shows how to set margins that survive a ₹2/Wp module swing. A 12-person EPC quoting 40 systems a month cannot re-issue PDFs by hand every time a distributor revises a rate card; that is an operations problem, not a pricing problem.

How Quickest Solar CRM Fits

Duty stacks and ALMM gates matter at exactly one moment: when your sales rep builds the quote on site. Quickest Solar CRM keeps the current module price, the DCR flag, the GST split, and the PM Surya Ghar subsidy inside the proposal itself, so a rep in Surat or Aurangabad sends a subsidy-ready, tax-correct PDF in 60 seconds instead of calling the office to check today's rate. When a distributor revises a price, you update it once and every new quote reflects it, with the 15-day validity clause printed on the document.

• Proposal Generator, 60-second branded PDF with DCR module selection, GST split, and PM Surya Ghar subsidy pre-filled.
• Quotation System, validity windows, pass-through clauses, and revision history on every quote.
• Sales Reports, see margin per deal when module prices move mid-pipeline.
• WhatsApp Follow-up, re-send a revised quote the same day a duty or price change lands, and track reads.

The free plan covers 10 proposals a month, which is enough to test the workflow on your next ten site visits; paid plans are on the pricing page.

What to Do This Week

Three concrete actions, doable inside seven days, to make import duty and ALMM rules stop being a margin risk:

1. Re-cost your standard BOMs at 2026 rates. Pull your last five won quotes, replace any 40 percent BCD assumption with the current 20 percent BCD plus 20 percent AIDC plus SWS stack, and re-derive your landed ₹/Wp. If your cost sheet still shows the pre-2025 rates, fix it before the next quote goes out.
2. Add the pass-through clause and a 15 to 30 day validity line to your quotation template. Copy the five clauses from the section above into your master template today, and brief your sales team on why the DCR line is non-negotiable for PM Surya Ghar jobs.
3. Split your price tracking into DCR and non-DCR columns. Ask your two main distributors for both rates in writing every Monday, and log them against the JMK benchmarks above so you spot divergence early and quote with the right module class for each project type.

Frequently asked questions

What is the import duty on solar modules in India in 2026?

In 2026, imported solar modules attract 20 percent Basic Customs Duty plus 20 percent Agriculture Infrastructure and Development Cess, plus Social Welfare Surcharge of 10 percent on those duties (about 4 percent of CIF value), plus 12 percent IGST on the duty-paid value. The non-creditable portion adds roughly 44 percent to the CIF price. These rates date from the Union Budget 2025-26 of February 2025, which restructured the earlier 40 percent BCD regime in force since April 2022.

What is the import duty on solar cells in India?

Solar cells imported for module assembly in India pay 20 percent BCD plus 7.5 percent AIDC plus SWS of about 2.75 percent, followed by 12 percent IGST. The lower stack for cells, versus modules, is designed to encourage domestic module assembly using imported cells, though ALMM List-II now requires Indian cells for subsidised projects from June 2026.

Is the 40 percent BCD on solar modules still applicable?

No. The 40 percent BCD on modules and 25 percent on cells applied from 1 April 2022 until the Union Budget 2025-26, presented on 1 February 2025, restructured the rates. Headline BCD fell to 20 percent, but a 20 percent AIDC on modules kept the combined non-creditable protection close to 44 percent of CIF, so the practical landed cost barely changed.

Can imported solar modules be used in PM Surya Ghar projects?

No. PM Surya Ghar Muft Bijli Yojana requires modules listed under MNRE's ALMM List-I, which effectively means domestically manufactured DCR modules. From June 2026, ALMM List-II additionally requires the cells inside those modules to come from approved Indian manufacturers. Imported modules, regardless of price or efficiency, cannot be used on subsidised rooftop projects.

What is the price difference between DCR and non-DCR modules in 2026?

In mid-2026, domestic non-DCR modules (Mono PERC) trade around ₹13.8 to 14.2 per Wp and TOPCon around ₹14.2 per Wp, according to JMK Research, April 2026. DCR modules carry a premium of roughly ₹1 to 3 per Wp because approved cell supply under ALMM List-II is still ramping up. The exact gap varies by brand and order volume.

Is IGST on imported solar modules refundable?

IGST at 12 percent on imported modules is not refunded, but it is available as input tax credit for GST-registered businesses, so it offsets your output GST liability. The real cost is working capital: you fund the IGST at the port and recover it over 30 to 90 days through your GST returns. BCD, AIDC, and SWS, by contrast, are pure costs with no credit.

Do solar EPCs need an IEC to import modules?

Yes. Any business importing solar modules into India needs an Importer Exporter Code (IEC) from the DGFT, a customs broker to file the Bill of Entry on ICEGATE, and BIS-registered products. Most small and mid-size EPCs find it simpler to buy from an importer or distributor who has already cleared customs, accepting a small margin on the landed price.

How should EPCs handle duty changes in customer quotes?

State a price-validity window of 15 to 30 days on every quote and add a pass-through clause covering changes in BCD, AIDC, SWS, GST, and ALMM-driven supply constraints after the quote date. Name the exact module make and model, state whether it is DCR, and reserve substitution rights for equivalent ALMM-listed models. These five clauses prevent a mid-pipeline notification from erasing your margin.
