The global sodium sulphite market is poised for steady expansion over the next decade, driven by increasing industrial applications, regulatory focus on water treatment, and rising demand from pulp & paper and textile industries. According to Future Market Insights (FMI), the market is valued at USD 1.15 billion in 2025 and is projected to reach USD 1.92 billion by 2035, growing at a compound annual growth rate (CAGR) of 4.8%.
The FMI report, “Sodium Sulphite Market Size, Share, and Forecast 2025–2035”, highlights the market’s steady growth trajectory, fueled by industrial modernization, environmental compliance requirements, and rising awareness of sodium sulphite’s role in water treatment, food preservation, and chemical processing applications.
Industrial Applications Propel Market Expansion
Sodium sulphite’s demand in pulp & paper production remains a major growth driver. As global paper consumption rises, the need for bleaching agents and anti-oxidants sustains sodium sulphite consumption. Between 2025 and 2030, the pulp & paper application is expected to account for 38% of global market growth, with a market value increase of USD 0.19 billion. From 2030 to 2035, the chemical processing and water treatment segments are projected to drive an additional USD 0.23 billion growth, reflecting stringent wastewater regulations and expanding industrial water treatment infrastructure.
“Industries are increasingly recognizing sodium sulphite not just as a chemical additive but as a critical component for regulatory compliance in water treatment and bleaching processes,” said an FMI market analyst. “Its stability, cost-effectiveness, and versatility across multiple applications underscore its enduring relevance.”
