The Vietnam Caustic Soda Market is witnessing rising penetration driven by expanding petrochemical complexes and green hydrogen integrations in industrial hubs like southern Vietnam. Market insights reveal the sector valued at around 332.85 thousand tons in 2025, projected to reach 367.89 thousand tons by 2032, with an estimated CAGR of 1.44% during 2026-32. This steady expansion underscores the pivotal role of key players in meeting surging demand across downstream applications.
According to Markntel Advisors, leading Caustic Soda companies in Vietnam play a significant role in sustaining this growing demand through strategic expansions and sustainability initiatives. Stavian Group, a major Vietnamese producer, exemplified this in April 2025 by signing a Memorandum of Understanding with France's HDF Energy to deploy HyPower fuel-cell technology at its caustic soda and petrochemical plants, targeting decarbonization and cleaner production processes. Similarly, Long Son Petrochemicals Co., Ltd., supported by Siam Cement Group (SCG), restarted its USD5 billion integrated complex in southern Vietnam in August 2025 after a ten-month pause, enhancing chemical infrastructure and bolstering upstream caustic soda needs for petrochemical stability. These targeted moves by key players not only fortify supply chains but also align with Vietnam's industrial growth trajectory.
