In mid-to-late August, China’s chemical industry remains in the traditional summer off-season. Persistent high temperatures affect stable operation of chemical facilities across multiple regions and reduce logistics turnover efficiency. The overall trading pace of bulk chemicals slows alongside a strong wait-and-see market sentiment, with prices of most basic chemical raw materials fluctuating within a narrow band. The silica sector continues its long-standing structural market divergence. However, the core driving force behind this industrial transformation is shifting. Beyond product performance optimization and downstream formula iteration, recycled manufacturing, full-life-cycle carbon footprint management and green supply chain certification have gradually become new benchmarks for evaluating enterprise competitiveness. Traditional general precipitated silica remains trapped in overcapacity and slim profit margins, with abundant circulating supplies. Most transactions are small spot orders to meet immediate demand, lacking upward price support. In contrast, low-carbon silica produced from solid waste such as rice husk ash, waste glass and industrial silicon slag, as well as functional silica manufactured with supporting CCUS carbon capture technologies, are widely favored by domestic and overseas downstream buyers. Orders grow steadily and product premium margins keep expanding, marking an obvious acceleration in the industry’s green transition.

　　From a supply perspective, conventional domestic silica production lines operate steadily. All facilities previously shut down for maintenance and environmental upgrades have resumed full production, delivering sufficient basic filler supply to satisfy regular procurement needs of traditional rubber and coating sectors. Nevertheless, the competitive gap between new and old production capacities continues to widen. Early precipitated silica lines adopting traditional mineral feedstock and sulfuric acid processes feature high energy consumption and large volumes of solid waste and wastewater discharge. Amid stricter environmental regulations and energy consumption dual-control policies, comprehensive production costs keep rising. Products from these lines can only compete in the low-end market at discounted prices, and long-standing inventory backlogs remain difficult to resolve. By comparison, newly constructed or revamped leading manufacturing bases prioritize solid waste recycling routes, converting agricultural and industrial silicon-containing waste into water glass feedstock paired with low-carbon reaction processes. The resulting silica matches the physical and chemical indicators of conventionally manufactured grades while delivering drastically lower carbon footprints. Capacity of these low-carbon lines is released in an orderly manner, and most output is pre-contracted for green tire, high-end silicone and export clients, leaving limited tradable spot goods and persistently low inventory. Manufacturers hold greater pricing power and avoid low-end price wars. Meanwhile, many leading enterprises deploy full-process digital quality control systems to record raw material sources, energy use and emission data, and issue complete LCA life cycle assessment reports to meet overseas supply chain audit standards, further raising industrial entry thresholds.

　　In terms of upstream raw materials and comprehensive costs, prices of sodium silicate, sulfuric acid and various modification additives have fluctuated moderately recently. Direct feedstock cost changes exert limited impact on finished silica pricing. Indirect expenses including overall energy consumption, environmental governance, carbon verification and certification services are becoming decisive factors for corporate profitability. Producers using traditional processes face rising pollution treatment fees and the risk of failing downstream carbon audits, which may exclude them from qualified supplier lists for European and American markets. Enterprises with circular production capacity reduce raw material procurement costs through solid waste recycling, while their low-carbon products command purchase premiums from downstream brand owners and mitigate cost pressure imposed by carbon tariffs in export markets, widening their overall competitive advantage. Market resources keep concentrating on leading players, shrinking the operating space for outdated small and medium-sized capacity and accelerating industrial consolidation and the phase-out of backward production lines.

　　Rising green material requirements across downstream application segments force silica suppliers to upgrade processes. As the largest downstream market for silica, major domestic and international tire brands have released carbon neutrality timelines, adding carbon footprint criteria to procurement specifications and prioritizing low-carbon high-dispersion modified silica, which drives growing purchases of silica made via recycling processes. The coating and adhesive sectors keep improving green product certification frameworks, with environmental performance of raw materials under close scrutiny for wood coatings, exterior architectural paints and sealants. Demand for matting and reinforcing specialty silica produced with low-emission processes expands steadily. In the new energy sector, supply chain audits for lithium battery separator coating, photovoltaic encapsulants and energy storage sealing products grow more stringent. Beyond impurity content and dispersibility, environmental data generated during raw material production is incorporated into evaluations, benefiting high-end silica manufacturers with complete supporting systems. Furthermore, sectors including pesticide suspension agents, food-contact materials and pharmaceutical excipients raise continuous standards for powder purity, production cleanliness and traceability, further pushing the industry toward greener and refined development.

　　The foreign trade export market enters a window for green transformation, and low-carbon silica emerges as a new growth driver for domestic raw material exports. Historically, China’s silica exports relied on low-priced general precipitated products, which were vulnerable to anti-dumping measures and carbon border trade barriers. At present, overseas buyers have shifted their procurement priorities, placing greater emphasis on complete environmental certifications, carbon footprint reports and stable supply capacity. Silica manufactured through recycling processes has successfully entered supply chains of large tire and new material enterprises in Europe and North America. New chemical projects in Southeast Asia also prefer compliant green powder raw materials. Incremental overseas orders divert domestic low-carbon silica supplies, easing pressure on high-end product availability and encouraging domestic manufacturers to continuously optimize production processes, forming a positive feedback loop driven by both domestic demand and export growth.

　　Industry institutions analyze that the divergent high-low tier market pattern of silica will persist in the short run. Industrial-grade general precipitated silica faces loose supply and demand and is expected to maintain weak volatile performance. Low-carbon recycled functional silica enjoys robust market resilience and firm pricing, supported by downstream green procurement policies and rising export demand. Approaching the traditional chemical stocking peak season in September, procurement plans from tire, coating and new material enterprises will be implemented sequentially, and silica with green certifications is likely to see concentrated purchasing activity. In the medium to long term, carbon management, recycling and green supply chain governance will become standard industry requirements, and the production model relying solely on low-price high-volume sales will gradually be phased out by the market.

　　For participants across the industrial chain, downstream product manufacturers may build a library of qualified green raw material suppliers in advance, establish long-term cooperation with silica producers equipped with recycling capacity, complete sample validation and supply chain audits ahead of schedule, and avoid supply disruption risks caused by subsequent environmental compliance requirements. Upstream manufacturers need to accelerate technical transformation, deploy supporting solid waste recovery and carbon capture facilities, complete life cycle assessments and relevant green certifications, develop specialty modified silica tailored for downstream low-carbon formulas, and transform from basic filler producers into green material solution providers. Trading and distribution enterprises can develop dedicated supply channels for green chemical raw materials, focusing on vertical tracks including new energy, high-end tires and export processing, and explore circulation value-added opportunities for low-carbon functional silica. In the long run, recycling technology, carbon management capabilities and comprehensive compliance certification systems will form lasting core competitive barriers for silica enterprises, and the green high-quality transformation of the industry will continue to deepen.
