Hyosung Vina Chemicals is preparing to take its No. 1 polypropylene (PP) unit in Cai Mep, Vietnam, offline for an extended maintenance program, a move that could tighten regional PP supplies as year-end approaches.
Market sources report that the company intends to halt operations by the end of October 2025, with the outage expected to last until early December. A contact in Vietnam indicated that preparations for the turnaround are already under way, although Hyosung Vina has not yet issued an official statement confirming the schedule.
The No. 1 unit, with an annual production capacity of 300,000 metric tons, is a key supplier of polypropylene used in packaging, automotive components, textiles, and household goods across Southeast Asia. Traders and downstream manufacturers are closely watching the situation, as even a temporary pause in output could influence spot prices and prompt buyers to secure alternative supply.
Situated in the industrial hub of Cai Mep near Ho Chi Minh City, Hyosung Vina Chemicals benefits from deep-water port access that enables efficient exports to neighboring markets. The planned maintenance reflects routine efforts to ensure plant reliability and optimize long-term performance, but the timing, coinciding with seasonal demand fluctuations, adds an extra layer of interest for market participants.
Analysts note that Southeast Asia’s polypropylene market has already been experiencing tight margins due to shifting feedstock costs and fluctuating global demand. The upcoming shutdown may provide temporary support to regional prices, while reinforcing the importance of scheduled maintenance in sustaining production stability for large-scale petrochemical facilities.
