By late August, China’s chemical industry remains in the traditional summer off-season. Persistent high temperatures restrict continuous production at midstream and downstream plants and reduce regional logistics efficiency. The overall market for bulk chemical commodities maintains a cautious wait-and-see sentiment, with prices of most raw materials lacking drivers for sharp fluctuations. Amid the interplay of supply and demand, low-carbon policies and new export regulations, market segmentation in the silica industry has become more pronounced. Low-end general precipitated silica is under dual pressure from overcapacity and weak demand, resulting in depressed prices. In contrast, high-dispersion modified silica and high-purity fumed silica for green tires, new energy materials and medical products hold firm quotations backed by rigid demand. Bargaining power differs noticeably between upstream and downstream participants, and the industrial focus continues shifting toward functionalization, low-carbon production and specialization.

　　In terms of overall supply landscape, most major domestic silica production lines have resumed full-capacity operation after annual maintenance and environmental upgrades in early August, delivering sufficient effective supply and stable nationwide product circulation. Nevertheless, production and sales patterns vary drastically across product lines. General industrial precipitated silica features low entry barriers, and concentrated capacity expansion over recent years has pushed supply far beyond actual market demand, leading to rising finished goods inventories, with prominent stockpiling in production areas including East and South China. To speed up inventory turnover and recover working capital, many small and medium-sized manufacturers have adopted profit-concession sales strategies. Continuous inflows of low-priced goods further squeeze industrial profit margins and intensify fierce competition in the low-end segment. For high-end functional silica, leading enterprises prioritize dedicated modified production lines for long-term strategic clients, with prelocked production schedules and limited tradable spot goods that sustain low inventory levels. Manufacturers adopt stable pricing strategies with almost no promotional price cuts. Meanwhile, high investment in low-carbon transformation and purification process upgrades prolong the launch cycle of new high-end capacity, which cannot quickly fill market gaps in the short run and further underpins the tight supply-demand balance for premium silica grades.

　　Regarding upstream raw materials and production costs, major feedstocks such as sodium silicate, sulfuric acid and industrial soda ash have fluctuated within a narrow range recently, showing no unilateral sharp rises or falls and limited price transmission to finished silica products. Notably, a growing number of leading enterprises are developing recycling production processes, preparing water glass from recycled silica slag, waste glass and agricultural residues, while gradually launching low-carbon production lines equipped with carbon dioxide capture and utilization systems. These measures cut carbon emissions and hedge against raw material price volatility. Silica produced via low-carbon processes qualifies for relevant requirements under the EU Carbon Border Adjustment Mechanism and commands additional premiums in overseas markets. Most small and medium-sized manufacturers still rely on traditional production routes, facing rising costs for environmental governance and energy consumption and putting them at a competitive disadvantage. The phase-out of backward industrial capacity is accelerating. In the long term, low-carbon production capacity will become a core market access threshold for silica enterprises competing domestically and internationally, and the development model relying solely on low-cost expansion is no longer viable.

　　Downstream segmented demand markets show uneven performance, with sluggish traditional sectors and steady expansion of emerging high-end tracks. Traditional fields including ordinary rubber components, construction fillers, general anti-corrosion coatings and feed additives suffer from insufficient end orders and low operating rates at downstream enterprises. Buyers follow an on-demand, sporadic restocking pattern with little bulk stockpiling, leading to slow consumption growth of standard silica and failing to drive a market recovery for low-end grades. The tire industry remains the most important downstream segment supporting the silica sector. With the steady recovery of domestic automobile consumption and improved prosperity in freight logistics, operating rates at major domestic tire manufacturers keep climbing. Coupled with national low-carbon policies, the production share of low rolling resistance green tires rises year by year. As a core reinforcing filler that optimizes tire wear resistance, tear resistance and rolling resistance, high-dispersion modified silica enjoys steady demand growth. Tire formulation enterprises continuously raise requirements for product purity, dispersibility and batch stability, forcing upstream silica producers to optimize modification processes. In addition, high-tech industries such as new energy battery separator coating, photovoltaic encapsulant adhesives, premium silicone rubber, electronic sealing materials, dental fillers and eco-friendly inks and coatings keep expanding, driving rising demand for ultra-fine, low-impurity, hydrophobically modified fumed silica. The domestic substitution of high-end silica speeds up gradually, breaking the long-term monopoly of overseas brands.

　　The foreign trade export market is undergoing profound structural adjustments, moving away from the past model of exporting low-end silica at low prices. Previously, China’s silica exports were dominated by general precipitated grades, which seized overseas markets with thin profit margins and frequently faced overseas anti-dumping investigations. Since 2026, domestic enterprises have optimized their export mix, with a significantly higher share of high-value products such as high-dispersion tire-specific silica, cosmetic-grade modified silica and high-purity fumed silica. Silica manufactured with low-carbon processes meets EU carbon tariff standards, and overseas purchasers are willing to pay premiums of hundreds of CNY per ton. New tire production bases under construction in Southeast Asia and the Middle East continuously release procurement demand for high-performance silica, forming an incremental export market for domestic premium products. The optimized structure of overseas orders effectively diverts domestic high-end supplies, eases domestic supply pressure and provides critical external support for firm pricing of premium silica.

　　Comprehensive analysis of industry factors shows that the silica sector has fully entered a structural development phase, and synchronized price swings across all product grades are a thing of the past. Segmented divergence will persist over the long term. In the short run, general low-end precipitated silica lacks positive catalysts and is likely to maintain weak range-bound fluctuations with strong upward resistance. Supported by multiple demand drivers including green tires, new energy advanced materials and overseas exports, high-end modified and fumed functional silica boasts sufficient market resilience, strong price resistance and rising added value. Industry institutions forecast that as the traditional “Golden September” chemical stocking cycle approaches in September, downstream tire, coating and rubber product manufacturers will gradually launch autumn restocking, creating upward expectations for the high-end silica market.

　　For participants across the industrial chain, downstream purchasing enterprises may adopt phased on-demand restocking strategies, closely track raw material trends and major manufacturers’ production schedules, reasonably control procurement rhythms and avoid cost increases caused by concentrated price hikes in peak seasons. Upstream producers need to accelerate product portfolio adjustment, cut output of homogeneous low-end products, continuously invest in R&D and production of low-carbon modified and special-purpose silica, improve supporting formulation services for downstream applications, deepen cooperation with high-end downstream clients and escape low-price competition through product differentiation. Trading and distribution enterprises should build refined supply systems, separate sales channels for high and low-end products, match formulation demands of diverse clients and tap value-added circulation potential for functional silica. In the long run, low-carbon production technologies, silica modification R&D capacity and customized downstream supporting services will determine the core competitiveness of silica enterprises, and the high-quality industrial transformation will continue to accelerate.
