Mid-August ushers in the peak of China’s traditional summer off-season for the chemical sector. Purchasing activity for bulk raw materials such as rubber, industrial coatings and general rubber & plastic additives has slowed down overall, with downstream enterprises opting for on-demand restocking and inventory compression. The long-standing industry norm of across-the-board price cuts and inventory liquidation in hot summer months has completely vanished from the precipitated silica market this year. The sector now features a stark two-tier operational landscape. Conventional industrial reinforcing precipitated silica sees sluggish trading and narrow price fluctuations, while vicious homogeneous price rivalry has noticeably cooled off. Fumed silica tailored for photovoltaic encapsulation, lithium battery protection and precision electronics suffers persistent supply shortages with firm and rising quotations. Meanwhile, carbon-negative silica manufactured via rice husk ash recycling and circular processes has secured numerous long-term overseas orders from Europe and the Middle East by virtue of its full-chain low-carbon footprint. This shift is quietly reshaping China’s import and export structure of silica. Industrial competition has moved beyond output scale rivalry and evolved into comprehensive contests centered on low-carbon processes, customized modification and multi-scenario adaptability.
Latest industrial monitoring data shows that the benchmark price of domestic silica edged slightly upward in early August. The average ex-factory price of mainstream industrial-grade precipitated silica stood at 6,000 CNY per ton on August 13, marking a 1.12% rise from late July and reversing the weak trend seen over the previous two weeks. This mild market upturn is not driven by a broad recovery in end-user demand, but arises from the combined effects of multiple practical factors. Sweltering temperatures force cooling systems to run around the clock at major production hubs in East and South China. Energy consumption for the harmless treatment of wastewater and waste gas has surged, coupled with amortized costs for equipment maintenance and online monitoring systems amid routine environmental inspections, pushing up comprehensive production costs. A large number of small and medium-sized manufacturers have chosen to steer clear of loss-making volume-driven competition and voluntarily cut operating rates. The overall industrial operating rate currently hovers between 75% and 80%. Leading conglomerates maintain full production amid abundant order backlogs, while smaller factories flexibly curb output to avoid inventory buildup, effectively easing the oversupply of low-end products. Northern production bases enjoy natural advantages: milder summer temperatures reduce cooling energy consumption, spacious factory layouts optimize production efficiency, and nearby procurement of quartz sand and sodium silicate slashes logistics expenses, granting them distinct overall cost superiority. The price gap between northern and southern supplies continues to widen, prompting many downstream traders to shift purchasing sources northward and reshaping regional commodity circulation patterns. Industrial surveys acknowledge that general-grade silica for tires and rubber hoses still grapples with overall overcapacity. Demand growth for tires supporting new passenger vehicles remains tepid, and only the stable replacement tire market provides bottom support with limited incremental room, precluding sharp price hikes for low-end grades.
Booming new energy industries fuel high-end demand and widen product price gaps, with non-tire consumption rising year after year and breaking the long-standing monopoly of tire applications. Domestic distributed photovoltaic power stations and large-scale ground-mounted energy storage projects are scheduled for concentrated commissioning in the third quarter, driving thriving production and sales of silicone sealants for photovoltaic module encapsulation. Ultra-fine hydrophobic fumed silica serves as a core thickening, anti-aging and anti-settling filler in adhesive formulations. Downstream adhesive enterprises have locked in all Q3 stocking orders in advance, leaving spot inventories nearly depleted and extending delivery cycles to two to three months. Power and energy storage battery makers keep upgrading safety coating systems for separators. High-purity nano silica significantly enhances the heat resistance and puncture strength of separators, leading to steady annual consumption growth. Major silicon material producers have pushed back their production schedules to late September.
Furthermore, the popularization of new energy vehicles is rewriting tire formulation standards. Compared with conventional fuel vehicle tires, NEV tires bear heavier vehicle weight and stronger instantaneous torque, requiring a 15%–20% higher dosage of silica for quiet, low rolling resistance green tire formulas. This fuels steady demand for high-dispersion modified precipitated silica, one of the few bright spots in the tire segment. Demand from daily care, oral care and anti-caking excipients for pharmaceutical tablets remains stable year-round. Food and pharmaceutical-grade high-purity silica is immune to chemical seasonal cycles with highly consistent order volumes. Ultra-high-purity fumed silica acts as a foundational material for sealing, shock absorption and thermal conductive components in wireless earbuds, smartwatches, micro sensors and other portable wearable electronics, where growth far outpaces traditional industrial sectors.
Import and export statistics released by the General Administration of Customs vividly illustrate the structural overhaul of China’s silica foreign trade landscape. From January to June 2026, China exported 769,000 tons of silica, a year-on-year increase of 11.90%, with total export value reaching USD 442 million, surging by 21.15%. Average export prices climbed concurrently, delivering robust growth in both volume and value. Imports totaled merely 40,000 tons, down 8.95% year-on-year, reflecting accelerated domestic substitution of high-end products. The European Union once ranked as China’s primary overseas market for silica. However, the full implementation of the EU Carbon Border Adjustment Mechanism (CBAM) has classified silica as a high-energy-consuming taxable product. Traditional quartz sand-sulfuric acid processed silica carries a large carbon footprint, sharply inflating tariff costs for European exports. Small and medium-sized manufacturers lacking low-carbon upgrading capacity and complete carbon emission ledgers have gradually exited the European market.In contrast, leading domestic enterprises’ years-long investment in rice husk ash recycling processes has yielded fruitful results. Adopting rice husks, an agricultural byproduct, as raw material replaces mineral quartz sand entirely. The production process consumes carbon dioxide, cutting carbon emissions per ton of finished product by over 60% compared with conventional techniques, and some variants achieve carbon negativity. These products have obtained EU green material certification and command an 8%–15% green premium in overseas sales, with order growth vastly outperforming standard industrial grades.
Market focus has steadily shifted to emerging economies in East Asia, Central Asia, the Middle East and North Africa, offsetting fluctuations stemming from shrinking European demand. Benefiting from zero-tariff policies under the RCEP, Vietnam, Indonesia, Thailand and other Southeast Asian nations have expanded capacity for rubber goods, construction sealants and daily chemicals, absorbing massive volumes of China’s mid-to-low-end precipitated silica. Intensive infrastructure and urban construction projects across the Middle East have triggered booming demand for construction sealants and industrial rubber parts in the UAE and Saudi Arabia, with import volumes jumping over 30% year-on-year in the first half of the year. Light industrial development in Central Asian countries sustains steady demand for basic silica fillers. Diversified global market layouts have eliminated the historic overreliance on European and American markets. To further evade carbon tariffs and trade barriers, several industrial leaders have initiated overseas capacity planning, establishing packaging and fine processing bases in Southeast Asia and the Middle East. Domestic factories undertake core purification and modification procedures, while overseas facilities handle packaging and delivery to comply with local trade policies and consolidate international market share.
Low-carbon circular production and solid waste recycling have become the core dividing line reshuffling the industry, with the phase-out of outdated capacity accelerating. The conventional process featuring quartz sand, soda ash high-temperature melting for water glass production followed by sulfuric acid acidification depletes massive mineral resources, generates over 4 tons of carbon emissions per ton of product and discharges large volumes of high-salinity wastewater, leading to rising annual environmental maintenance costs. Nowadays, innovative large-scale technologies including rice husk ash resource utilization and carbon dioxide carbonization are gaining traction. Silicon elements are extracted from rice husk ash, waste heat from incineration is recovered for production heating, and carbon dioxide replaces sulfuric acid in the acidification stage. The byproduct weakly alkaline sodium carbonate solution is recycled repeatedly, completely resolving high-salinity wastewater treatment challenges. This approach not only consumes agricultural solid waste and curbs air pollution from open-air rice husk burning but also drastically slashes carbon emissions and total energy consumption, delivering superior purity and dispersibility tailored to stringent requirements of green tires and premium daily chemicals.
Many leading enterprises have built blockchain-enabled full-chain carbon tracing systems that record carbon emission data throughout rice husk procurement, production processing and finished product delivery, securing International Environmental Product Declarations (EPDs) and granting them unparalleled advantages in overseas bidding and access to major brand supply chains. On the contrary, countless small workshops cannot afford hefty investments in environmental equipment upgrades and carbon accounting frameworks, nor do they possess formula modification R&D capabilities. They can only compete for scattered low-end orders at depressed prices amid shrinking profit margins, driving accelerated industrial capacity concentration among top players. Industry institutes predict the combined market share of the top five enterprises will surge substantially by the end of 2026, and the elimination of inefficient backward capacity will continue.
Industrial analysts foresee a steady divergent trend for the market in the coming months. From late August to early September, China will remain entrenched in the summer off-season with no drastic price swings anticipated. Low-grade general silica will maintain mild narrow fluctuations, while tight supply of high-end fumed silica for photovoltaics, lithium batteries and electronics will persist alongside stable firm pricing. Upon entering September, rubber processing, industrial coating and waterproof material manufacturers will kick off the traditional autumn production peak, coupled with concentrated downstream stocking ahead of the Mid-Autumn Festival and National Day holidays, ushering in a moderate phased upturn across the overall silica market.
In the long run, the extensive development model reliant on mineral raw materials and low-price volume sales has come to an end. Customized surface modification technologies, closed-loop low-carbon circular production, and balanced domestic and overseas market deployment will constitute the three pillars determining corporate core competitiveness. Silica will thoroughly shed its single identity as a conventional rubber reinforcing filler and evolve into a versatile inorganic new material widely applied across six major sectors: new energy storage, automobile manufacturing, fine daily chemicals, biomedicine, precision electronics and agricultural & forestry circular materials, propelling sustained industrial upgrading toward high quality, green development and refinement.
