Vietnam Caustic Soda Market Size: Forecast (2026-2032)

The Vietnam Caustic Soda Market size is valued at around 332.85 thousand tons in 2025 and is projected to reach 367.89 thousand tons by 2032. Along with this, the market is estimated to grow at a CAGR of around 1.44% during the forecast period, i.e., 2026-32.

Vietnam Caustic Soda Market Outlook:

Vietnam’s caustic soda industry is positioned for steady upward growth, supported by rapid industrialization, infrastructure expansion, and increasing demand from core downstream sectors. For instance, the Vietnam News Agency (VNA) highlighted that national industrial output rose by 8.7% year-on-year in mid-2024, with chemical and basic material production playing a central role in this recovery. Likewise, rising demand from alumina refining, pulp & paper, textiles, and PVC manufacturing continues to boost caustic soda consumption, as these industries depend on the chemical for neutralization and bleaching processes. Additionally, government initiatives to strengthen domestic chemical production and raw-material security are fostering long-term resilience. For reference, the Ministry of Industry and Trade (MOIT) has prioritized investment in core chemical clusters in the northern and southern provinces, aimed at reducing import dependence.

Similarly, Vinachem, Vietnam’s leading state-owned chemical group, has reported stable revenue growth in 2024 and has been modernizing chlor-alkali facilities to enhance production efficiency. However, challenges persist. Domestic supply meets only about half of total demand, prompting Vietnam to import large volumes of sodium hydroxide each year, about 62 million kg in 2023, according to the World Bank’s WITS trade database. High electricity costs and the need to co-produce chlorine make production balancing difficult. Furthermore, environmental compliance rules introduced under Vietnam’s 2025 Chemical Law are expected to tighten quality and safety standards, raising operational costs.

Vietnam Caustic Soda Market Recent Developments:

April 2025: Stavian Group (Vietnam) and HDF Energy (France) signed a Memorandum of Understanding in April 2025 to jointly explore hydrogen-power solutions at Stavian's caustic soda (and other petrochemical) plants, deploying HDF's HyPower fuel-cell technology, aimed at decarbonizing caustic soda production.
August 2025: Long Son Petrochemicals Co., Ltd., backed by Siam Cement Group (SCG), restarted its USD5 billion integrated petrochemical complex in southern Vietnam after a ten-month halt. This revival strengthens Vietnam's chemical infrastructure, boosts demand for upstream inputs like caustic soda, and supports domestic supply stability within the growing petrochemical chain.

Vietnam Caustic Soda Market Drivers:

Government Support and Manufacturing Expansion

Vietnam’s Caustic Soda Industry is gaining momentum through policy incentives and industrial expansion programs. For instance, the Vietnam Chemical Law 2025, approved by the National Assembly, introduces stricter safety standards and investment facilitation for chemical producers, aiming to raise national chemical output by 15–20% by 2030. Additionally, the Ministry of Industry and Trade (MOIT) has outlined plans for three major chemical manufacturing clusters in Hai Phong, Nghi Son, and Ba Ria–Vung Tau, each designed to support large-scale chlor-alkali facilities.

For reference, Duc Giang Chemical Group JSC broke ground on a USD47 million caustic soda plant in 2025, while Southern Basic Chemicals JSC upgraded its electrolysis lines, raising capacity from 40,000 to 50,000 tons annually. Likewise, Vedan Vietnam Enterprise Co., Ltd. completed construction of a specialty-chemical plant with an annual output of 20,000 metric tons of caustic soda, which reflects growing industrial demand and supportive policy confidence, jointly accelerating domestic caustic soda production and reducing Vietnam’s 50% import reliance.

Growing Focus on Water Treatment and Environmental Compliance

Vietnam’s increasing emphasis on industrial wastewater management and clean-water infrastructure is a major growth driver for this market. For instance, the Ministry of Natural Resources and Environment (MONRE) reported in 2024 that over 70% of Vietnam’s industrial zones were upgrading to meet national wastewater standards, requiring large volumes of caustic soda for pH control and neutralization.

Additionally, the Vietnam Water Supply and Sewerage Association estimates that urban water demand will reach 12 million m³/day by 2030, driving higher chemical use for purification. Consequently, industrial users typically consume 5–10 kg of caustic soda per cubic meter of wastewater treated. Furthermore, new wastewater treatment projects in Binh Duong and Hai Phong, worth over USD300 million collectively, are expanding demand for water-treatment chemicals, directly boosting caustic soda consumption nationwide.
