SCC to halt Long Son petrochemical complex amid ongoing feedstock disruptions
Thailand’s Siam Cement Public Company Limited (SCC) has decided to temporarily suspend operations at its Long Son Petrochemicals complex in Vietnam due to continued challenges in feedstock supply.
In its update dated April 22, 2026, the company stated that prolonged instability in the Middle East has impacted raw material availability and significantly increased sourcing costs. Despite efforts to secure supplies from alternative routes outside the Strait of Hormuz, supply continuity could not be fully maintained.
As a result, SCC plans to shut down the Long Son Petrochemicals facility around mid-May 2026. The suspension is expected to result in fixed cash costs of approximately THB 250 million (around $6.8 million) per month during the downtime.
This move follows an earlier shutdown of its Rayong Olefins unit in Thailand, which was also affected by similar supply constraints. The company noted that these disruptions are beyond its control and are unlikely to ease in the near term.
During the shutdown period, SCC will carry out maintenance activities and accelerate work on its Long Son expansion project, which aims to increase the use of ethane as feedstock to improve long-term efficiency and flexibility.
The company added that its other chemical operations and business units will continue to run, with necessary adjustments based on current market conditions.
