China’s supporting policies related to carbon peaking and carbon neutrality are constantly improving. Sectors such as green tires, environmentally friendly coatings and new energy energy storage materials are developing at an accelerated pace, driving the powder filler industry to transform toward low energy consumption, high functionality and environmental friendliness. The silica industry has abandoned the extensive capacity expansion model and entered a brand-new development cycle featuring technology-driven growth and customized supporting supply. The market for conventional precipitated silica is well supplied with fierce homogenized competition. Manufacturers face long-term pressure from raw material and energy consumption costs. Profit margins of most small and medium-sized producers keep shrinking amid increasingly fierce survival competition. In contrast, surface-modified functional silica can be tailored in performance according to downstream product formulas to deliver multiple functions including reinforcement and toughening, matting, hydrophobicity and moisture resistance, anti-settling, flame retardancy and insulation. It is widely used in green tires, auxiliary materials for energy storage batteries, photovoltaic sealants, waterborne anti-corrosion coatings, medical polymer products, electronic packaging materials and other fields. Market demand rises steadily, making functional silica a core product prioritized by major chemical enterprises. The focus of industrial competition is gradually shifting to modification processes, formula development and the delivery of integrated application solutions.

　　The upstream raw material market operates generally stably. Prices of basic feedstocks such as metallurgical silicon, water glass, sulfuric acid and soda ash fluctuate mildly, providing solid support for silica production costs. Different silica grades show obvious gaps in cost absorption capacity. Oversupply dominates the general silica market, leaving manufacturers with weak bargaining power. Most rising costs of raw materials, energy and labor have to be borne by producers themselves, leading to low overall industrial profitability. Various functionally modified silica has high technical barriers. Most suppliers establish long-term designated supporting partnerships with high-end downstream clients and enjoy reasonable pricing space to cover investment in formula development, multi-batch sample testing, refined modification processing and finished product performance verification, achieving notably better profit performance than standard general grades. Meanwhile, low-carbon renovation, environmental inspections and work safety supervision are routinely carried out across China’s chemical sector. Outdated production lines with high energy consumption, substandard emissions and backward processes are gradually phased out. Effective production capacity and high-quality customer orders keep concentrating on leading enterprises equipped with clean production capacity and a complete independent R&D system, continuously strengthening industrial agglomeration effects.

　　Structural divergence on the supply side continues to deepen. Domestic capacity for general precipitated silica is sufficient. Major producing regions maintain high operating rates with abundant circulating goods and large inventories held by traders. Discounted sales to speed up capital turnover frequently occur in the low-end market, continuously curbing upward price potential for ordinary grades. High-end products including fumed silica, high-dispersibility silica dedicated to tires, hydrophobically modified silica for lithium battery separators and reinforcing silica for silicone rubber are restricted by exclusive modification formulas, precision synthesis equipment and strict process control. Their capacity expansion proceeds slowly with tight spot supplies. Most mainstream manufacturers adopt order-based scheduling, and spot goods available on the market are limited. Multiple high-end silica production lines have been commissioned nationwide in recent years, accelerating import substitution. Nevertheless, technical gaps remain for sophisticated products such as ultra-high-purity electronic-grade and medical specially modified silica, leaving substantial room for import substitution in high-end markets.

　　Downstream demand maintains a divergent pattern: subdued demand in traditional segments and continuous incremental growth in emerging green tracks. In traditional application markets such as rubber components, ordinary civil shoe materials and general architectural 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 activity. Benefiting from the rolling implementation of global low-carbon regulations, low rolling resistance eco-friendly tires gain rising market penetration in the green tire industry. As a core reinforcing filler, high-dispersibility functional silica enjoys stable rigid demand and consolidates 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 quickly, 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 functional 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 grow steadily, continuously expanding silica application boundaries and tapping new market growth points.

　　Foreign trade remains resilient alongside ongoing 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 and supports 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 layouts, reducing shipments of low-end general silica and focusing on developing overseas clients for various modified high-end silica. They access premium overseas markets via differentiated products, avoid vicious low-price competition and lift overall export returns.

　　Inventory levels exhibit prominent structural characteristics. Factory and circulating inventories of general industrial silica stay elevated 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 resistance to market volatility. To guarantee stable raw material supply and mitigate risks of supply shortages and price hikes during peak seasons, large downstream end-users have signed long-term supply agreements with silica manufacturers to lock product specifications, delivery quantities and transaction 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 unlikely to undergo fundamental changes. Standard products can hardly achieve notable market improvement, while high-end functionally modified silica boasts strong market resilience backed by steady downstream rigid 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 rise 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 ended. 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 green application scenarios and continuously iterate functional silica products can fully seize dividends brought by the upgrading of the new material industry under the dual-carbon goal and build long-term stable competitive advantages amid industrial reshuffling.
