Capacity Enhancement Initiative

The temporary closure is timed to coincide with the near completion of the company's expansion project. This shutdown aims to enable Tamilnadu Petroproducts to increase its production capacity to 250 tonnes per day (TPD), representing an enhancement to the company's manufacturing capabilities.

The expansion project appears to be in its final stages, with the planned closure serving as the integration phase for new infrastructure and equipment. This approach may minimize long-term operational disruptions while maximizing the efficiency of the capacity upgrade process.

The December 23, 2025 start date for the shutdown indicates planning by the company's management. The 6-7 week timeframe suggests an integration process that may involve:

• Installation and commissioning of new equipment
• Integration of expanded production lines
• Testing and optimization of enhanced systems
• Staff training on upgraded facilities

This planned approach demonstrates the company's commitment to operational improvements in the petrochemicals sector.
