About Chemplast Sanmar Limited

Chemplast Sanmar Limited, a flagship of The Sanmar Group, has a six-decade legacy in India’s speciality chemicals sector. Established originally as Chemicals and Plastics India Limited in 1962, the Company has steadily expanded into a diversified producer of speciality chemicals and polymers.

It is India’s leading producer of Speciality Paste PVC resin with around 66% market share and 83% of domestic production capacity. Through its wholly owned subsidiary, Chemplast Cuddalore Vinyls Limited (CCVL), the Company is also the second-largest Suspension PVC manufacturer in India and the largest in South India. Its broader portfolio includes Chloromethanes, Caustic Soda, Hydrogen Peroxide, and Refrigerant Gases, catering to diverse industries such as pharmaceuticals, agrochemicals, textiles, paper, alumina, irrigation, and infrastructure.

Chemplast operates integrated, backward-linked facilities across Tamil Nadu (Mettur, Berigai, Cuddalore, Vedaranyam) and Puducherry (Karaikal). These units incorporate Zero Liquid Discharge systems, captive salt pans, and marine terminals to strengthen cost efficiency and supply chain resilience.

The Company has continually marked milestones—PVC resin production at Mettur in 1967, the Cuddalore Suspension PVC facility in 2009, and the commissioning of new Paste PVC and Custom Manufactured Chemicals Division (CMCD) blocks in 2023-24 and 2024-25.
