April 10, 2026 — The global potassium hydroxide (KOH, caustic potash) market is poised for steady growth, with a projected value of USD 3.84 billion by 2034, expanding at a CAGR of 4.90% from 2026 to 2034, according to a new report by IMARC Group. The market, valued at USD 2.49 billion in 2025, is primarily fueled by surging demand from the agricultural sector (over 40% of total consumption for potassium-based fertilizers) and the battery industry, where KOH is a critical electrolyte in alkaline and emerging battery technologies. Additional demand comes from biodiesel production, pharmaceuticals, soaps & detergents, and industrial cleaning applications. The report highlights that industrial-grade KOH dominates the market share, while high-purity and electronic-grade KOH is the fastest-growing segment, driven by the semiconductor and electronics manufacturing sectors. Key producers, including Olin Chlor Alkali and INEOS Inovyn, are focusing on ultra-low-carbon production technologies to meet global sustainability targets.
