Caustic Soda Manufacturers In China

As the global core of caustic soda capacity (over 50 million tons in 2024), Chinese manufacturers supply high-purity liquid, flake and granular caustic soda (CAS:1310-73-2, UN:1824, HS:2815120000) via advanced ion-exchange membrane technology. Our products meet international standards, with 50% concentration liquid caustic featuring strong stability and granular caustic offering rapid dissolution.

Applications span alumina production (100-150kg caustic per ton alumina), papermaking bleaching, textile dyeing, and wastewater pH adjustment. Leveraging East China's port access and Northwest China's energy advantages, we’ve built a robust supply chain—2025 H1 exports surged 52.79% YoY, with FOB prices 15% lower than Southeast Asia.

We adhere to ISO standards, use moisture-proof packaging for safe transport, and offer customized specifications with technical support. From raw material inspection to customs clearance, full-process quality control ensures reliable, cost-effective caustic soda supply for global clients.
