India, Indonesia, Laos Solar Tariffs 2026

Quick Answer

Why This Matters for EPCs

India, Indonesia, and Laos together supplied over $1.6 billion in solar products to the US market in 2024, real, current supply, not a niche corner of the market. If your sourcing touches any of these three countries, or a module assembler using their cells, this isn't a future risk to watch, it's already raising landed costs today, since CBP is collecting cash deposits at the preliminary rates while the case works through its final stages.

What This Case Actually Is

Trade lawyers call this "Solar IV," the fourth in a recognizable sequence of US trade actions against imported solar cells: Solar I targeted China in 2012, Solar II added Taiwan in 2015, Solar III hit Cambodia, Malaysia, Thailand, and Vietnam through a circumvention inquiry in 2023 and new orders in 2025. This one, filed July 17, 2025 by the Alliance for American Solar Manufacturing and Trade, whose members include Hanwha Q Cells USA, First Solar, and Mission Solar Energy, targets crystalline silicon photovoltaic cells, whether or not assembled into modules, from India, Indonesia, and Laos.

The petition named 43 producers or exporters in India, 54 in Indonesia, and 8 in Laos. The scale of what's being targeted is real: solar product imports from these three countries totaled $1.6 billion in 2024, $817 million from India, $423 million from Indonesia, $388 million from Laos, a dramatic rise from a fraction of that just two years earlier.

The Confirmed Rates

*Rate based on facts available with adverse inferences.

These are the preliminary countervailing (subsidy) duty rates, confirmed directly from Commerce's own fact sheet, dated February 24, 2026. Separate antidumping (pricing) duties apply on top of these and are calculated independently, Commerce's preliminary AD determination was announced April 23, 2026, though the exact rate table wasn't located for this piece. Industry analysts have flagged that India's mandatory respondents withdrew from the AD investigation specifically, which typically triggers "adverse facts available" and could push India's combined AD rate above 200%, worth treating as an informed expectation rather than a confirmed figure until the final AD rate is independently verified.

The Scope Question: What Actually Gets Covered

This is the detail most coverage glosses over, and it changes how you should think about exposure. Coverage is determined by where the cell was made, not where the module was assembled. A module assembled in Vietnam using cells manufactured in Indonesia would be subject to these duties. A module assembled in Indonesia using cells manufactured in Vietnam would not be. Tandem cells combining crystalline silicon with perovskite or other materials are also covered, consistent with how Commerce has scoped prior solar cases.

Practically, this means the country printed on a module's country-of-origin label isn't the determining factor, the cell's actual manufacturing origin is. Verifying a supplier's module assembly location alone doesn't confirm duty-free status if the underlying cells came from a covered country.

Timeline

What's Still Genuinely Uncertain

The ITC's October 19 vote is the step that actually determines whether these duties become permanent orders, not a formality. The ITC already found preliminary injury back in August 2025, which makes an affirmative final vote more likely than not, but it isn't guaranteed, and the exact final rates for AD specifically haven't been independently confirmed here. Don't treat October 26 as a locked date for orders to take effect, treat it as the date they'd take effect if the ITC affirms.

What EPC Teams Should Do Now

Common Mistakes to Avoid

• Assuming this is fully resolved because Commerce issued a final determination. The ITC's own final vote, October 19, 2026, is still pending and is the step that actually confirms the orders.
• Judging exposure by a module's country-of-origin label alone. Coverage follows cell manufacturing origin, not assembly location.
• Treating the India >200% AD figure as a confirmed rate. It's an informed industry expectation tied to the mandatory-respondent-withdrawal scenario, not an independently verified final number.
• Assuming all suppliers in a covered country face the same rate. Firm-specific rates vary substantially, from under 81% to over 143% in the confirmed CVD figures alone.
• Waiting for final orders before adjusting sourcing conversations. Cash deposits are already being collected at preliminary rates, the cost impact is current, not future.

Where Reslink Fits In This Conversation

A client asking whether their project's module pricing is about to change needs a real answer built on the specific supplier's actual cell origin, not a general country-level assumption. Reslink's proposal workflow lets you model project economics against the confirmed current rates for a specific supplier relationship, and rebuild that model quickly once the ITC's October vote and any final AD rate land, so a client sees where their actual exposure sits rather than a headline percentage that may not apply to their specific supply chain.

Frequently Asked Questions

Q1. Does this affect modules already installed or under contract before these duties took effect?

Not addressed in the sources checked for this piece. AD/CVD duties generally apply to entries of merchandise from the point cash deposits begin, worth confirming the exact entry date rules with a trade counsel for any specific shipment already in transit or under contract.

Q2. Are these the only duties that apply, or do others stack on top?

Other duties can apply separately. Section 201 safeguard tariffs applied to most countries through February 2026, though India and Indonesia were notably excluded from that specific program. Country-specific tariffs and other trade measures may also apply independently, worth checking a specific shipment's full duty exposure rather than assuming AD/CVD is the only cost.

Q3. Why did India's mandatory respondents withdraw from the AD investigation?

Not addressed in the sources checked for this piece. The withdrawal itself is confirmed, and it's expected to result in "adverse facts available" treatment, typically leading to a higher assigned rate, but the underlying reasons for the withdrawal weren't found.

Q4. Could other countries face a similar case next?

Analysts have flagged this as a real pattern, prior cases pushed production toward new countries, which then draw fresh scrutiny once volumes rise. No new petition against a specific country was confirmed in the sources checked for this piece, worth monitoring rather than treating as settled.

Q5. Is this the same as the Section 232 polysilicon tariffs already covered on this site?

No, separate and stacking, see our Section 232 Polysilicon Tariffs guide for the full mechanics. Section 232 applies broadly by product classification regardless of country, and specifically excludes raw polysilicon from its ad valorem component. This AD/CVD case applies to finished cells and modules by specific country and company. A product could be subject to both simultaneously.
