The global caustic soda market size is projected to reach USD 64.3 billion by 2030, growing at a compound annual growth rate (CAGR) of 4.9% from 2024 to 2030, according to a new report by Grand View Research, Inc. The market is expected to experience steady growth due to rising demand across a wide range of industries, including textiles, pulp and paper, organic chemicals, and more. Caustic soda plays a vital role in various industrial processes such as bleaching, cleaning, and chemical synthesis, making it an indispensable chemical in modern manufacturing.
One of the key factors driving this market is the increasing demand for alumina, particularly from the automotive sector. The Asia Pacific region is witnessing significant growth in automobile production, and alumina is a crucial raw material used in the manufacture of lightweight and durable vehicle components. Since caustic soda is used in the refining of bauxite to produce alumina, this rising demand from the automotive industry is expected to substantially contribute to the market’s expansion over the forecast period.

However, certain challenges may restrain the growth of the market. Caustic soda production is highly energy-intensive, and fluctuations in energy prices can directly impact its production cost. Additionally, the uneven production output across regions, influenced by regulatory restrictions and supply chain disruptions, can result in price volatility, which may limit market growth to some extent.
Furthermore, as caustic soda is co-produced with chlorine through the chlor-alkali process, any changes in chlorine demand or production can influence the availability and pricing of caustic soda, adding an additional layer of complexity to the market dynamics.
In terms of application, the textile industry emerged as the dominant segment in the global market in 2023. The growing consumer preference for high-quality fabrics with improved texture, strength, and vibrant coloration has led to an increase in the use of caustic soda in textile processing.
It is widely used for processes such as scouring and mercerization, which enhance the dye uptake and appearance of fabrics. Given these factors, the textile segment is expected to continue leading the market over the forecast period, driven by evolving fashion trends, urbanization, and rising disposable incomes across emerging economies.
