With the continuous upgrading of China’s advanced manufacturing and new material industries, downstream application fields keep raising requirements for the comprehensive performance of powder fillers. The silica industry is gradually moving away from the old model of seizing market share through capacity expansion and entering a value competition stage focused on enhancing product added value, customized modification and supporting application services. General precipitated silica has sufficient production capacity and faces fierce homogeneous competition, suffering from prolonged profit pressure. Many small and medium-sized manufacturers are confronted with shrinking profit margins. In sharp contrast, various high value-added modified silica can achieve multiple functions including reinforcement, matting, hydrophobicity, anti-sagging, thermal conductivity regulation and insulation protection via flexible surface modification processes. They are widely applied in green tires, supporting materials for energy storage batteries, photovoltaic packaging auxiliary materials, high-end anti-corrosion coatings, biomedical polymers and other fields, with steadily growing market demand. Such silica has become the core category prioritized by chemical enterprises. The focus of industrial competition has shifted from output competition to R&D of modification formulas, product stability control and delivery of complete application solutions.

　　The upstream raw material market operates generally stably. Prices of basic raw materials such as metallurgical silicon, water glass, sulfuric acid and soda ash fluctuate within a narrow range, providing solid underlying support for silica production costs. Different product grades show a notable gap in cost bearing capacity. Oversupply prevails in the general silica market, leaving manufacturers with weak bargaining power. Most rising costs of raw materials, energy and labor have to be absorbed by producers themselves, resulting in low overall profitability. High value-added modified silica has high technical barriers and is mostly tailor-made for high-end downstream clients with stable long-term cooperation. Manufacturers enjoy reasonable pricing space to cover investment in formula development, multi-batch sample verification, refined modification processing and finished product performance testing, achieving better profit performance than standard grades. Meanwhile, low-carbon renovation, environmental inspections and work safety supervision are carried out routinely across China’s chemical sector. Outdated production lines with high energy consumption and substandard emissions continue to exit the market. Production capacity and high-quality orders keep concentrating on leading enterprises equipped with clean production capacity and independent R&D systems, continuously strengthening industrial agglomeration effects.

　　The structurally divergent pattern on the supply side continues to deepen. China boasts massive domestic capacity for general precipitated silica. Major producing regions maintain high operating rates with abundant circulating goods and obvious inventory backlogs among traders. Discount sales to accelerate capital turnover frequently occur in the low-end market, constantly limiting upward price potential for ordinary grades. On the contrary, high value-added products including fumed silica, high-dispersibility silica for tires, special hydrophobically modified silica for lithium battery separators and reinforcing silica for silicone rubber are restricted by modification formulas, precision synthesis equipment and strict process control. Their capacity expansion proceeds slowly with tight spot supplies. Mainstream factories generally adopt order-based production scheduling, and spot goods available on the market are limited. In recent years, multiple high-end silica production lines have been commissioned nationwide, accelerating import substitution. Nevertheless, technical gaps remain for sophisticated products such as ultra-high-purity electronic-grade and medical specially modified silica, leaving considerable room for import substitution in high-end markets.

　　The divergent trend of downstream demand persists, featuring weak demand in traditional sectors and continuous incremental growth in emerging high-end tracks. In traditional application markets such as rubber parts, ordinary shoe materials and civil interior wall coatings, terminal consumption recovers gently. Downstream factories hold high finished goods inventory and operate cautiously. Procurement mainly consists of small on-demand replenishment with little willingness for bulk stockpiling, leading to quiet overall trading atmosphere. Benefiting from the implementation of global low-carbon regulations, the market penetration of low rolling resistance eco-friendly tires rises year by year in the green tire industry. As a core reinforcing filler, high-dispersibility silica enjoys stable rigid demand and underpins the fundamental market of the industry. The new energy industry maintains rapid expansion. Supporting materials for power batteries, energy storage cells and photovoltaic sealing components develop rapidly, imposing stringent standards on silica in terms of purity, uniform particle size, dispersion stability and resistance to high and low temperature aging. Orders for various customized high value-added silica remain sufficient with lengthened production lead times. In addition, niche markets including food contact fillers, pharmaceutical excipients, aerospace sealing materials, heavy-duty anti-corrosion special coatings and electronic encapsulation fillers keep expanding, continuously broadening the application boundaries of silica and unlocking new growth potential.

　　Foreign trade retains overall resilience alongside continuous optimization of export product mix. Steady development of basic manufacturing in Southeast Asia, the Middle East, Latin America and other regions sustains regular procurement demand for silica, supporting stable total export volume from China. However, long-standing external uncertainties including the Carbon Border Adjustment Mechanism, international trade barriers, fluctuating ocean freight rates and geopolitical conflicts constrain foreign trade activities. Domestic exporters have adjusted operational strategies, cutting the export share of low-end general silica and focusing on developing overseas clients for high value-added modified silica. They tap into premium overseas markets with differentiated products, avoid vicious low-price competition and improve comprehensive export returns.

　　Inventory levels exhibit prominent structural characteristics. Factory and circulating inventories of general industrial silica stay at high levels with a long de-stocking cycle. Prices lack upward momentum in the short run and fluctuate weakly. Most modified high-purity, electronic-grade and medical-grade silica adopts a build-to-order model with low routine inventory, sustaining a prolonged tight supply-demand balance and stronger capability to resist market fluctuations. To guarantee stable raw material supply and mitigate risks of stockouts and price hikes in peak seasons, large downstream end-users have signed long-term supply agreements with silica manufacturers to lock product specifications, delivery quantities and prices. The upstream-downstream collaborative supporting model is becoming increasingly mature.

　　In the short term, the structurally segmented operating pattern of China’s silica market is difficult to reverse. Standard products are unlikely to achieve notable market improvement, while high value-added modified silica boasts strong market resilience backed by rigid downstream demand. With the arrival of the traditional peak sales season known as Golden September, operating rates of downstream manufacturers producing tires, coatings, rubber products and adhesives are expected to rebound and drive a recovery in overall market trading. From a medium and long-term perspective, the era of extensive capacity expansion for the silica industry has come to an end. Customized R&D for clients, supporting technical services and low-carbon clean production capacity will form enterprises’ core competitive barriers. In the future, enterprises that dig deep into segmented application scenarios and continuously iterate high value-added silica products can fully capture dividends brought by the upgrading of the new material industry and build long-term competitive advantages amid industrial reshuffling.
