Asia
In China, the average price of Caustic Soda edged down from ~USD 95.16/MT (FOB) in July to ~USD 94.70/MT in August. India saw a larger fall of about 8.2%, from ~USD 201.97/MT (CIF) to ~USD 185.49/MT. In China, a large alumina refinery in Shandong cut its purchase price at the end of July, pressuring regional values, although contract prices in Shanxi later rose and Guangxi held steady, keeping the overall market balanced. In India, domestic plants ran at healthy rates, with one major producer at 82% utilisation and adding a new flaking unit, which improved local supply and reduced reliance on imports. Demand from alumina, soaps, detergents and textiles stayed steady.
Europe
In Germany, caustic soda averaged approximately USD 360.82/MT (FOB) in July and eased to about USD 355.90/MT in August, a decline of ~1.4%. Chlor-alkali plants ran at low rates, with utilisation falling to 64.8% in July, as weak demand for chlorine, the co-product, limited production. Caustic soda stocks fell 10.5% in July, pointing to tighter availability, but softer summer buying kept prices from rising.
North America
In the USA, average caustic soda prices declined from nearly USD 412.00/MT (FOB) in July to roughly USD 399.13/MT in August, down ~3.1%. Producers had raised prices earlier in the year, helped by the closure of a chlor-alkali unit at Lake Charles in late 2025. However, Olin expected stronger caustic soda volumes in Q3, adding supply to export markets, while higher natural gas and power costs squeezed margins. Weaker EDC and VCM conditions also weighed on the wider chlor-alkali chain.
Analyst Insight
According to Procurement Resource, caustic soda is expected to trade in a steady range as lower European stocks offset ample Asian supply, with energy costs keeping a floor under producer offers.

Asia
In China, the prices of Caustic Soda were ~USD 103.25/MT in April and ~USD 95.00/MT in June, showing a ~8.0% decrease. The market weakened due to adequate domestic availability, cautious purchasing and supplier pressure to secure orders. Maintenance at some chlor-alkali plants provided temporary support, but inventories remained sufficient. Export demand absorbed part of the surplus, while alumina producers remained the strongest domestic buyers. Demand from paper, textiles, detergents and general chemicals stayed subdued, keeping procurement limited to immediate requirements. In India, the prices of Caustic Soda were ~USD 153.14/MT in April and ~USD 182.90/MT in June, showing a ~19.4% increase. Prices were supported by firmer regional supply conditions, higher replacement costs and stronger industrial purchasing. Import dependence and tighter availability from nearby suppliers also strengthened seller offers.
Europe
In Germany, the prices of Caustic Soda were ~USD 493.83/MT in April and ~USD 392.70/MT in June, showing a ~20.5% decrease. Strong chlor-alkali production and rising inventories increased market availability, reducing buyers’ need for additional spot purchases. Demand from pulp and paper, alumina, detergents, water treatment and chemical industries remained weak. Electricity costs limited more aggressive producer reductions, but could not offset the pressure from high stocks and subdued consumption.
North America
In the United States, the prices of Caustic Soda were ~USD 370.00/MT in April and ~USD 458.00/MT in June. Export demand reduced material available to domestic spot buyers and strengthened producer pricing. Higher energy and transportation expenses added cost pressure, while industrial consumption from alumina, chemicals, pulp and paper provided support. Domestic demand was not strong enough to create a severe shortage, but export commitments kept the market firm.
Analyst Insight
According to Procurement Resource, caustic soda prices may remain regionally mixed. Export demand and energy costs should support Western markets, while China may stay under pressure from adequate supply and cautious buying.
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.
