Potassium Hydroxide prices in Germany, the highest-cost reporting region, rose 3.8% in Q2 2026 to USD 1,090.00/MT from USD 1,050.00/MT in Q1, extending a recovery that followed a genuine growth-correction-recovery cycle through 2025. Globally, the average rose from USD 918.40/MT in Q1 to USD 954.90/MT in Q2, a 4.0% gain. For H2 2026, a global average of USD 930.00-1,050.00/MT is expected, with firm demand from fertilizer, battery, and chemical manufacturing applications likely to keep this market on its established recovery path.
Potassium Hydroxide, commonly abbreviated KOH and also known as caustic potash, is produced through the electrolysis of potassium chloride brine, a process closely related to chlor-alkali chemistry. It serves as a key raw material for potassium-based fertilizers, liquid soaps and detergents, alkaline battery electrolytes, and biodiesel production through transesterification, alongside broader use across chemical manufacturing. Its price behavior tends to move through distinct phases of growth, correction, and recovery, reflecting its close linkage to chemical processing, fertilizers, and industrial applications rather than a single steady trend. Potassium chloride feedstock costs, electricity costs at electrolysis facilities, and demand from fertilizer, battery, and biodiesel applications are what drive prices in this market.
The outlook for Potassium Hydroxide through H2 2026 stays firm, continuing the recovery phase that followed 2025's mid-year correction. Growing demand from alkaline battery production and biodiesel manufacturing, alongside steady fertilizer and chemical processing consumption, should keep this market on a consistent upward path, even as the characteristic growth-correction-recovery pattern of this market suggests periodic pauses are likely.
The main upside risk is a further tightening of potassium chloride feedstock availability or electricity costs, which would push production costs higher across every region tracked in this report. The main downside risk is a repeat of the kind of mid-cycle correction seen in 2025, which could interrupt the current recovery phase.

| India | 860.00 - 970.00 | Growing fertilizer and industrial demand drives firming |
| China | 760.00 - 850.00 | Lowest cost given substantial domestic production capacity |
German Potassium Hydroxide prices averaged USD 1,090.00/MT in Q2 2026, the highest of any region tracked here, up 3.8% from USD 1,050.00/MT in Q1, as elevated electricity costs at electrolysis facilities continued supporting this market.
