India Caustic Soda Market Outlook
According to the report by Expert Market Research (EMR), the India caustic soda market reached a volume of over 3.96 million metric tonnes (MMT) in 2024. Aided by the rising demand from key end-use sectors such as paper and pulp, textiles, chemicals, and aluminium, the caustic soda market in India is anticipated to witness steady growth at a CAGR of 5.50% during the forecast period of 2025 to 2034, reaching a volume of 6.76 MMT by 2034.
Caustic soda, also known as sodium hydroxide (NaOH), is an essential inorganic chemical used in a wide range of industrial processes. It plays a vital role in the manufacturing of various products such as detergents, textiles, paper, alumina, and soaps. Its strong alkaline properties make it indispensable in neutralising acids, removing heavy metals, and separating components during production processes.
Market Size and Share
The Indian caustic soda market, owing to its strategic significance in industrial operations, has maintained a robust presence in the Asia-Pacific region. In 2024, the country accounted for a significant share of the regional caustic soda demand, supported by rapid industrialisation and infrastructure development. The market is dominated by major domestic producers who have expanded their production capacities to meet both domestic and export requirements.
The market is primarily concentrated in industrial belts such as Gujarat and Maharashtra, where large-scale chemical and textile units operate. Gujarat alone accounts for a dominant share of India’s total caustic soda production, owing to favourable policies, proximity to raw materials, and access to port infrastructure.

Drivers of Growth
The India caustic soda market is being driven by a multitude of demand-side and supply-side factors:
-
Rising Demand in the Alumina Industry: The aluminium sector utilises caustic soda extensively in bauxite refining for alumina extraction. With the rising demand for lightweight aluminium in construction, packaging, and transportation, the caustic soda market benefits directly.
-
Growth of the Textile and Paper Sectors: Caustic soda is used in textile mercerisation and pulp bleaching. With the expansion of the domestic textile and paper manufacturing capacities, consumption of caustic soda is poised to grow.
-
Government Focus on Industrial Expansion: The Indian government’s initiatives under “Make in India” and investments in smart industrial corridors are spurring growth in downstream manufacturing sectors, further enhancing the demand for caustic soda.
-
Urbanisation and Infrastructure Growth: The rise in urban population and infrastructure projects drives the demand for construction materials, chemicals, and packaging—indirectly fuelling caustic soda usage.
Technology and Advancements
Technology plays a crucial role in ensuring the competitiveness of the Indian caustic soda industry. The dominant manufacturing process in India has transitioned from diaphragm and mercury cell technologies to membrane cell technology, which offers superior energy efficiency and environmental performance.
Advanced real-time monitoring systems, integrated digital control units, and automated material handling systems are being employed to optimise production. Additionally, R&D efforts are being directed towards developing value-added chlor-alkali derivatives, enhancing the profitability of integrated chemical operations.
Furthermore, significant investment is being directed toward the development of green hydrogen and chlorine production to support the sustainability goals of the chlor-alkali industry.
