Tamilnadu Petroproducts Limited has suspended operations at its Manali Propylene Oxide plant after a government directive halted propylene supplies, raising concerns about supply chain disruptions in the automotive sector.
India's Ministry of Petroleum & Natural Gas (MoPNG) has ordered refineries and oil marketing companies to divert crude-based products away from downstream sectors. This measure aims to strengthen domestic energy security as Middle East tensions rise. Refineries must now focus on producing Liquefied Petroleum Gas (LPG) for household use, reducing the availability of propylene for industrial applications.
Propylene is a key chemical derived from oil refining. It is essential for producing Propylene Oxide at TPL’s Manali plant. The government’s directive has stopped propylene supply to the facility, forcing TPL to suspend PO production. The company has issued a force majeure notice, citing total stoppage of raw material supplies.
The halt in PO production at Manali is expected to affect the global automotive sector. Propylene Oxide is a critical precursor for polyurethanes, which are used in automotive seating, dashboards, and insulation. Car manufacturers depend on these materials for vehicle interiors.
Precision Wires India Ltd, a major winding wire producer in Mumbai, recently reported supply chain disruptions linked to the Middle East conflict. The company noted rising inflationary pressures as some suppliers face difficulties.
Industry analysts warn that even a short disruption at TPL could create bottlenecks for Original Equipment Manufacturers (OEMs). These manufacturers rely on just-in-time delivery of chemical components. Any delay could affect production timelines for automotive interiors and other products.
TPL stated in its regulatory filing that it cannot yet assess the full financial and operational impact of the shutdown. The company continues to monitor the situation as the government maintains its focus on domestic fuel stability.
