Global Caustic Soda Market Stood at a Volume of About 85.92 MMT in 2025

Caustic soda or sodium hydroxide forms an essential part of the manufacturing process of various products such as paper, aluminium, soaps, detergents, and bleach, among others. It is usually manufactured by the electrolysis of sodium chloride solution (brine). Lime soda process is another method of manufacturing caustic soda where ‘trona’ ore is treated with lime to produce sodium hydroxide. FMC and Solvay, major key players in the caustic soda market, use the lime soda process to produce caustic soda in their Wyoming plants.

China, the largest producer of caustic soda, has seen a slump in its exports in the past five years due to an increase in demand domestically amidst supply constraints. This growing domestic demand for caustic soda will lead to an increase of over 60% in China’s per capita consumption of caustic soda in the coming decade.

The alumina industry is one of the largest emerging consumers of caustic soda, driving the global market growth of the caustic soda industry. The increase in the utilization of caustic soda in the alumina industry is due to a shift by the automotive manufacturers towards aluminium to decrease vehicle weights and to reduce emissions. The caustic soda demand for alumina production in Northeast Asia increased by almost 23% in 2018 as compared to 2017.

Pulp and paper, and chemical industries are other significant industries where caustic soda is finding growing application. Caustic soda is used extensively as an esterification and transesterification reagent and cleaning agent, finding application in the chemical pulping process which involves sulphite, sulphate and soda. It is also used as a bleaching agent in industries like pulp and paper, textile, dye and more.
