According to official information from the Vietnam Trade Office in India, on September 29, 2025, the Directorate General of Trade Remedies (DGTR) of India issued a notice initiating an anti-dumping investigation concerning solar encapsulants originating in or imported from Korea, Thailand, and Vietnam.
Case details
- Product under investigation: Solar encapsulants, with related HS codes: 39019000, 39201019, 39201099, 39202090, 39206190, 39206290, 39209919, 39209932, 39209939, 39209992, 39209999. (The HS codes are provided for reference only; the specific product scope is defined in the initiation notice).
- Petitioner: M/s RenewSys India Pvt. Ltd. – one of the leading producers of solar materials in India.
- Product Control Numbers (PCN): The petitioner has proposed its own PCN system for comparing domestic sales prices and export prices. DGTR requires interested parties to submit comments, with detailed explanations, on the product scope as well as the PCN system within 15 days of receiving the initiation notice. Determination of PCNs is a key factor in calculating the dumping margin, as it distinguishes costs and prices of different product types under investigation.
- Period of investigation:
- For dumping practices: April 1, 2024 – March 31, 2025.
- For injury assessment: the periods 2021–2022, 2022–2023, 2023–2024, and the dumping investigation period.
Obligations of Vietnamese enterprises
Vietnamese producers/exporters must submit comments and questionnaire responses to DGTR within 30 days of receiving the initiation notice. If additional time is needed, companies may request an extension from DGTR before the deadline. Failure to submit on time may result in DGTR treating the enterprise as non-cooperative and relying on adverse facts available, which could lead to the imposition of high anti-dumping duties.
Enterprises should also note that if DGTR does not designate mandatory respondents, all exporters are required to respond to the investigation questionnaire. If an enterprise fails to respond, responds incompletely, or provides inaccurate information, DGTR may consider it as insufficient cooperation and impose the highest anti-dumping duty.
Recommendations from the Trade Remedies Authority of Vietnam (TRAV)
To assist enterprises in timely responding to the case, TRAV recommends that enterprises:
- Carefully review their export activities of the investigated products to India in order to assess potential impacts.
- Study India’s anti-dumping investigation regulations, particularly regarding procedures, deadlines, and submission requirements.
- Proactively submit comments on the product scope and PCN system proposed by the petitioner, while also providing opinions on other issues of the case.
- Prepare and submit questionnaire responses truthfully, in detail, comprehensively, and within the deadline. Enterprises may consider engaging legal consultancy services to ensure compliance with DGTR’s technical requirements.
- Contact and closely coordinate with TRAV to receive timely information, guidance, and support throughout the investigation process.
To protect their legitimate interests, manufacturers and exporters should familiarize themselves with the procedure and actively contact Vietnam Antidumping Law Firm specializing in anti-dumping and trade remedy for timely assistance.
