Sodium Sulfate Industry Anchors New “15th Five-Year” Track: Fifth National Industry Conference Convenes in Zhenjiang
QYJSSA/November 17,2025
Key Highlights
l Strategic opportunity: The conference, held at the outset of the “15th Five-Year Plan,” offered dual calibration of policy and market signals for the sodium sulfate sector, stressing that high-purity sodium sulfate should be used to capture the emerging energy-storage materials opportunity.
l Technical pathway: Technology providers and leading enterprises focused on high-purity preparation and low-carbon processes such as MVR (mechanical vapor recompression) to lay the process foundation for large-scale supply of sodium-ion battery feedstock.
l Supply chain & exports: New-energy expansion is reshaping the sodium sulfate supply landscape. Companies must strengthen product certification, quality stability and supply-chain traceability to meet international trade barriers.
l Action items for industry: Near term—upgrade standards and build compliance systems; medium to long term—use industry-university-research collaboration and recycling to forge a “value-upgrade + greening” moat.

Strategic Window: Policy Guidance and International Trade Trends Move in Parallel
The Fifth National Sodium Sulfate Industry Conference, held in late October in Zhenjiang, Jiangsu, arrived at a critical strategic window at the start of the “15th Five-Year Plan.” Experts from bodies such as the China Academy of International Trade and Economic Cooperation (Ministry of Commerce) and the China Chemical Information Center provided systematic judgments on domestic and international economic and petrochemical industry patterns, offering policy adaptation guidance for the sodium sulfate sector.
The conference pointedly stressed that under the dual drivers of “new-quality productive forces” and carbon-neutral goals, the value chain must treat low-carbon production and trade compliance equally. Enterprises are encouraged to embed stronger compliance and carbon-emissions management mechanisms within export structures and contract terms, thereby consolidating long-term export competitiveness for sodium sulfate (sodium sulfate decahydrate / Glauber’s salt).
Technology-driven Upgrading: Standards for Energy Storage and High-end Materials
Technical sessions, led by institutions including the Institute of Process Engineering (Chinese Academy of Sciences), concentrated on “high-purity sodium sulfate and high-value utilization,” with special emphasis on potential applications in new-energy storage—particularly as feedstock for sodium-ion batteries—and other high-performance material fields. Experts discussed purity-grade standard systems, testing specifications and industrialization pathways for feedstock products, arguing that standards upgrading is the primary condition for shifting from traditional glass and detergent raw materials toward critical energy-storage materials.
Demonstration results shared by leading firms—such as by-product sodium sulfate recovery and MVR low-carbon production technologies—not only reduce energy consumption but also provide reproducible process routes for high-purity production.
Production Innovation & Supply-Chain Restructuring: Green Processes, Supporting Capabilities and Market Signals
Supply-chain topics were a conference focal point: from raw-material sourcing and refining capacity to downstream battery manufacturing and buyer requirements at home and abroad, the sodium sulfate supply pattern is being reshaped in step with new-energy expansion and trade policy changes. Delegates shared two clear paths:
l Raise resource utilization via by-product recovery and process integration.
l Implement low-carbon process retrofits—MVR, waste-heat recovery and similar measures—to lower per-unit carbon footprint.
Concurrently, exporters noted that international market trends and trade barriers require higher investments in product certification, quality stability and supply-chain transparency to secure competitiveness in international tenders and long-term supply agreements.
Industrial Coordination & Regulatory Closed-Loop: From Fragmented Competition to Collaborative Development
The conference emphasized a dual track of regulation and industry self-discipline: build a regulatory closed-loop and traceability system spanning raw materials, production and export. This not only supports enterprise compliance but also establishes credible quality credentials for higher-end markets. On industrial coordination, participants recommended industry alliances and industry-university-research cooperation to form collaborative mechanisms for standard setting, shared testing and recycling loops, thereby lowering the overall industry transformation cost and accelerating entry into the energy-storage materials track.
Looking Ahead: Building Long-term Competitiveness through “Value-upgrade + Greening”
At the start of the “15th Five-Year Plan,” the sodium sulfate industry’s next phase should not be pure capacity expansion or cautious preservation. Instead, firms must center efforts on product high-purification, low-carbon processes and supply-chain traceability to construct long-term business models aimed at new-energy and high-end materials. In the short term, companies should focus on technical retrofits and standardization—accelerating high-purity sodium sulfate quality certification and perfecting export compliance systems. In the medium to long term, build moats through supply-chain collaboration, recycling and market expansion.
Overall, embracing demand from energy-storage materials while treating green, low-carbon operation as a non-negotiable baseline will determine which enterprises can transform from traditional raw-material suppliers into strategic, high-value material providers during the “15th Five-Year” period.
