Asia
In Asia, the caustic soda price graph remained relatively stable with mild upward movement by the end of the quarter. In China, the prices were ~0.69 RMB/kg (Spot, 32% Lye) in January and ~0.69 RMB/kg in March, with caustic soda prices increasing by ~0.69%. Prices declined in January due to ample supply and weak downstream demand, especially from alumina buyers, who procured cautiously. However, post-holiday restocking and lower-than-expected inventories supported a recovery in February. By March, geopolitical tensions in the Middle East and disruptions in the Strait of Hormuz tightened global energy supply, raising production costs and supporting prices. Trade flows showed China exported significantly higher volumes while imports declined, indicating strong overseas demand support. In India, the prices were ~35.14 INR/kg (Spot, 48% lye) in January and ~36.42 INR/kg in March, reflecting an increase of ~1.66%. The Indian market followed a similar pattern, with initial softness due to balanced supply and demand, followed by gradual recovery supported by rising global costs and improved downstream procurement. On the other developments, Indian Peroxide Limited announced a 400 TPD chlor-alkali (caustic soda) plant at Dahej, Gujarat, expandable to 800 TPD, with Nuberg EPC as contractor; the project targets October 2026 commissioning and integration with hydrogen peroxide operations.
Europe
In Europe, caustic soda prices showed a stronger upward movement compared to Asia. The prices were ~0.30 GBP/kg (CIF, Felixstowe) in January and ~0.39 GBP/kg in March, with prices increasing by ~27.50%. The increase was driven by rising energy costs and supply tightening linked to geopolitical tensions. Disruptions in shipping through the Strait of Hormuz increased freight costs and constrained imports, while energy-intensive chlor-alkali production faced cost pressure. Steady downstream demand allowed these higher costs to pass through to prices.
North America
In North America, caustic soda prices largely resembled the Chinese trend, with relatively stable pricing and limited overall movement. The market was influenced by balanced supply-demand conditions early in the quarter, followed by cost-side pressure from rising energy prices and geopolitical tensions. Global logistics challenges and higher transportation costs supported prices toward the end of the quarter, while steady downstream demand maintained overall market stability.

Asia
The Asian caustic soda market experienced a predominantly declining trajectory throughout the fourth quarter. In China, prices weakened progressively as supply remained abundant while downstream demand, particularly from the alumina sector, stayed subdued. The prices were about 118 USD/MT (Spot, 32% Lye) in October and around 106 USD/MT in December.
Operating rates across production facilities remained elevated, contributing to ample availability in the market. The beginning of the quarter saw brief upward momentum driven by anticipated maintenance shutdowns and relatively balanced supply-demand dynamics, but this was short-lived as fundamentals reasserted pressure on pricing. As the quarter progressed, downstream buyers adopted conservative purchasing strategies, primarily procuring material on an as-needed basis.
The alumina industry, a major consumer of caustic soda, faced operational challenges and price pressures of its own, leading to reduced offtake and limited purchasing activity. This cautious approach from end-users prevented any meaningful recovery in caustic soda valuations. Trade data revealed continued strength in export volumes compared to the previous year, while import activity contracted significantly, reflecting domestic surplus conditions. The Indian market mirrored these trends, with prices following a similar downward path amid weak downstream sentiment and adequate supply availability. The prices were about 408 USD/MT (Spot, 48% Lye) in October and around 401 USD/MT in December.
Europe
European caustic soda markets slight adjustment during the fourth quarter. The United Kingdom market experienced downward movement early in the period before stabilizing at lower levels. The prices were about 455 USD/MT (48-50%, CIF Felixstowe) in October and around 406 USD/MT in December. This pattern reflected both seasonal demand softening and recalibration following previously elevated price points from earlier in the year.
Market participants displayed cautious sentiment throughout the quarter, with buyers maintaining lean inventory positions and suppliers facing limited pricing power. The market transition from elevated year-on-year comparisons to more sustainable levels characterized much of the period's activity. By quarter-end, prices had settled into a consolidation phase, suggesting the market had largely absorbed the earlier downward corrections.
North America
The North American caustic soda market demonstrated a slight declining trend during the fourth quarter. While directional movement was less pronounced than in other regions, fundamentals remained challenging with adequate supply conditions and measured demand from key consuming sectors. Market participants maintained discipline in purchasing activities, contributing to the modest downward pressure on pricing throughout the period.
At room temperature, Caustic Soda is known to be a white crystalline odourless solid that is synthetically manufactured. It is an inorganic compound with the ability to absorb moisture and carbon dioxide from the air. When miscible in water or neutralised with acid, it liberates substantial heat, that may be ample to ignite combustible materials. As Caustic Soda is corrosive in nature, It is generally utilised as a solid or a 50% solution.

To produce Caustic Soda from lime soda process, a weak liquor through a filter and soda ash are collected in the dissolving tank where they are converted into an intermediate milk of lime in the presence of hot water, cauticisers and thickeners. This results in the formation of dilute Caustic Soda, which is further filtered.
