Long Son Petrochemical Complex Plans to Resume Production in Q2 2027
The Long Son Petrochemical Complex in Ho Chi Minh City plans to resume production in the second quarter of 2027 and complete trial operations by the end of the third quarter. Its operator is advancing a $500 million upgrade to add imported U.S. ethane as a supplementary feedstock. Production has been suspended since late May 2026 due to disruptions in Middle Eastern feedstock supplies.
On November 11, Long Son Petrochemicals Co., Ltd. (LSP), a subsidiary of Thailand’s SCG Group, announced that it was accelerating an upgrade project and a comprehensive maintenance program for its petrochemical complex in Long Son Commune, Ho Chi Minh City. The complex is scheduled to restart in the second quarter of 2027. After production resumes, the company expects to increase output gradually and complete trial operations by the end of the third quarter of 2027, about three months ahead of the original schedule.

The complex has suspended production since late May 2026 because of disruptions in feedstock supplies from the Middle East. During the shutdown, LSP has inspected and maintained equipment and advanced modifications to add ethane as a supplementary feedstock. Some units have been shut down completely and cleared of hydrocarbon gas to allow key work to proceed.
The upgrade project has a total investment of $500 million and is expected to use ethane imported from the United States. LSP said the move aims to diversify feedstock sources, strengthen supply chain resilience, and reduce greenhouse gas emissions and costs. General Director Kulachet Dharachandra said geopolitical changes had disrupted the company’s operating plans. LSP is using the shutdown to accelerate the ethane integration project and is currently prioritizing a safe restart of the complex in the second quarter of 2027.
At the peak of the comprehensive maintenance program, about 5,000 workers are expected at the complex. LSP plans to use AI-assisted digital tools to manage access, work permits and contractor qualifications, and to monitor air quality and odors in real time. The complex had an initial investment of more than $5 billion and a designed annual capacity of 1.4 million metric tons of polyolefin products.
