What happened

The Directorate General of Trade Remedies (DGTR), under the Ministry of Commerce and Industry, has concluded its anti-absorption review of the anti-dumping duty on imports of Insoluble Sulphur originating in or exported from China PR. The review was initiated on an application shared by the company, which alleged that exporters were absorbing the duty and thereby making it ineffective.

The Final Findings are dated 18 September 2026 in Case No. AD (AA)-02/2026 and were notified in the e-Gazette on 29 September 2026.

What the DGTR recommended

• Duty on Insoluble Sulphur from China PR to be modified from USD 307 per MT to USD 485 per MT, with the existing form of duty retained.
• The modified duty to apply retrospectively from 3 July 2026, the date from which provisional assessment of such imports began.
• The duty table covers goods originating in China PR exported from any country including China PR, and goods from any country other than China PR and Japan when exported from China PR, both at 485 USD per MT.

Background

The original anti-dumping investigation covered China PR and Japan, and duties recommended in March 2025 were imposed by the Ministry of Finance in June 2025 for five years. Under the current schedule, imports linked to China PR attracted 307 USD per MT.

The investigation period for the absorption review, that is the absorption period, was 1 July 2025 to 31 December 2025 (six months), with prices compared against the original investigation period of 1 January 2023 to 31 December 2023. The authority used an exchange rate of 1 US$ = Rs. 88.65.

The authority notes that the applicant was found in the original investigation to be the sole producer of the product in India, accounting for 100% of Indian production, and constitutes the domestic industry. No producer or exporter from China PR shared a questionnaire response. MRF Limited shared user and economic interest questionnaire responses; an oral hearing was held on 4 August 2026.

What it means for investors

Insoluble Sulphur is used as a vulcanising agent in rubber applications, so tyre and rubber makers are the buyers. A higher duty on Chinese imports raises the landed cost for importers of the competing product. The recommendation is subject to consideration and notification by the Ministry of Finance, so it is not yet in force as a duty change.

The company states the findings are expected to support fair competition in the domestic market and strengthen the effectiveness of trade remedial measures for Insoluble Sulphur, and that it is not possible to quantify the financial impact at present. It will inform the exchanges of further material developments.
