The Directorate General of Trade Remedies (DGTR) has extended the statutory deadline for completing India’s ongoing anti-dumping investigation into imports of Solar Encapsulants excluding EVA Encapsulants originating in or exported from China PR.
Under Case No. AD(OI)-34/2025, the investigation was originally due for completion by 28 September 2026. The Central Government has now granted a further three-month extension, moving the deadline to 28 December 2026.
DGTR notified the extension through F. No. 6/39/2025-DGTR dated 27 August 2026, following an Office Memorandum issued by the Tax Research Unit (TRU), Department of Revenue, Ministry of Finance.

The key change is the statutory timeline for completing the investigation.
| Particular | Earlier Position | Revised Position |
|---|---|---|
| Investigation | AD(OI)-34/2025 | AD(OI)-34/2025 |
| Product | Solar Encapsulants excluding EVA Encapsulants | Same |
| Country of Origin/Export | China PR | Same |
| Completion Deadline | 28 September 2026 | 28 December 2026 |
| Extension | — | 3 months |
| Nature of Update | Ongoing investigation | Procedural timeline extension |
Revised completion deadline28 December 2026
Legal Basis for the Extension
The Central Government granted the extension through Office Memorandum No. CBIC-190349/54/2026-TRU dated 21 August 2026, issued by the Tax Research Unit (TRU), Department of Revenue, Ministry of Finance. DGTR’s notice dated 27 August 2026 records the extension and revises the schedule for completion.
The extension is made under the applicable provisions of the Customs Tariff Act, 1975 and the Anti-Dumping Rules, 1995.
Which Products Are Covered?
The investigation concerns “Solar Encapsulants excluding EVA Encapsulants” originating in or exported from China PR. Solar encapsulants are materials used in photovoltaic panels to protect and bond solar cells within the panel structure. This investigation concerns encapsulants other than EVA (ethylene-vinyl acetate) encapsulants.
Before determining whether their imports fall within scope, businesses should verify:
- The specific chemistry or type of the encapsulant being imported
- The country of origin or export of the product
This Is a Procedural Extension, Not a Duty Decision
The DGTR notice does not make any finding on dumping, injury, or the imposition of anti-dumping duty. It only extends the statutory period for completing the investigation, and contains no final determination or duty recommendation.
The extension should not be read as an indication that anti-dumping duty will necessarily be imposed. The investigation remains ongoing.
Why the Extension Matters to Solar Industry Stakeholders
Solar encapsulants are an important input in photovoltaic panel manufacturing, so developments in this investigation can matter to manufacturers, importers, suppliers and procurement teams.
The three-month extension means regulatory uncertainty about the outcome will continue longer than originally anticipated. Businesses sourcing non-EVA solar encapsulants from China may need to factor this into procurement, pricing and supply-chain planning.
Importers
Confirm whether the encapsulant being imported falls within the investigation’s product scope.
Solar Module Manufacturers
Assess potential procurement and pricing implications arising from the continued investigation.
Chinese Suppliers
Monitor the progress of the investigation and any subsequent DGTR developments.
Procurement Teams
Consider the possibility of continued regulatory uncertainty through December 2026.
Industry Stakeholders
Monitor DGTR notifications for subsequent developments, including the disclosure statement and final findings.
What Businesses Should Do Now
The changed deadline does not require immediate action, but companies connected with the product should use the additional time to review their position.
Verify Product Scope
Determine whether your solar encapsulant is a non-EVA encapsulant falling within Case No. AD(OI)-34/2025.
Verify Country of Supply
The investigation concerns products originating in or exported from China PR. Verify the relevant origin and supply-chain details.
Monitor DGTR Developments
The investigation must now conclude on or before 28 December 2026. Keep monitoring DGTR notifications as the revised deadline approaches.
Factor Uncertainty Into Planning
Consider the potential impact of the investigation on longer-term procurement and pricing decisions, without treating the extension as confirmation that duty will be imposed.
Key Takeaways
DGTR is investigating imports of Solar Encapsulants excluding EVA Encapsulants from China PR under Case No. AD(OI)-34/2025.
The original deadline of 28 September 2026 has been extended by three months to 28 December 2026.
Office Memorandum No. CBIC-190349/54/2026-TRU dated 21 August 2026.
The extension is not a finding of dumping or injury, and no anti-dumping duty recommendation has been made.
Businesses should check whether their product and Chinese supply chain fall within the investigation’s scope, and continue monitoring DGTR developments.
