Chemplast Sanmar Halts Karaikal EDC Plant After Closure Order

CHENNAI / KARAIKAL — Specialty chemical manufacturer Chemplast Sanmar Limited has formally informed Indian stock exchanges that the Puducherry Pollution Control Committee has issued directions ordering the immediate closure of its Ethylene-Di-Chloride (EDC) manufacturing plant located in Karaikal, Puducherry.

According to regulatory filings submitted under Regulation 30 of the Securities and Exchange Board of India (SEBI) Listing Obligations and Disclosure Requirements (LODR) Regulations, 2015, the directions mandate that operations at the EDC facility cease forthwith. The plant cannot resume production until further orders are issued by the regulatory body.

Background and Sequence of Regulatory Actions

The closure order by the Puducherry Pollution Control Committee follows an earlier prohibition order issued by the Chief Inspector of Factories, Puducherry. Both administrative actions stem from a minor fire incident that occurred at the Karaikal EDC facility on July 17, 2026, at approximately 10:30 AM.

Key details of the sequence include:

• Incident Report: The fire occurred within the EDC manufacturing unit. No injuries or casualties were reported.

• Factory Inspection Order: Following an on-site inspection, the Inspector of Factories issued a prohibition order restricting further plant operations.

• Pollution Control Committee Directions: On July 22, 2026, the Puducherry Pollution Control Committee issued formal directions ordering the complete shutdown of operations until compliance requirements are fulfilled.

• Capacities Affected: The Karaikal facility houses a captive EDC manufacturing capacity designed to support downstream polyvinyl chloride (PVC) chemical production.

Corporate Compliance Response and Operational Impact

Chemplast Sanmar stated in its official exchange filing that it is actively implementing necessary corrective measures across the affected equipment, instrumentation, and safety installations. The company is preparing a comprehensive compliance report to submit to the Puducherry Pollution Control Committee to request a formal revocation of the shutdown directions.

While the physical damage caused by the fire remains covered under the company's insurance policies, the complete financial and operational impact of the downtime is currently being evaluated. Industry analysts note that extended downtime at the captive EDC plant may require Chemplast Sanmar to temporarily rely on imported raw materials to maintain downstream PVC production schedules.

Industry Position and Governance
