In mid-September 2026, China's white carbon black industry entered a phase of deepening structural market trends. The overall market has completely departed from the traditional model where price fluctuations were driven by costs, and fully stepped into a new competition cycle marked by demand divergence, technology-based pricing and premium pricing for high-end products. The supply-demand polarity in the industry has become increasingly obvious. Mass-produced precipitated white carbon black faces continuous overcapacity, low and volatile prices and shrinking profit margins amid fierce homogenized competition. In contrast, high-end functional products including highly dispersible modified white carbon black, hydrophobic white carbon black, ultra-low impurity special white carbon black and fumed silica see sustained demand growth, full order books, extended delivery cycles and stronger premium capacity, serving as the core driver of industrial growth. The spot price of white carbon black witnessed narrow fluctuations this month, lacking momentum for sharp rises or falls, and structural trends have become the main theme running through the whole year.

　　On the raw material cost side, the quotations of core upstream materials remained generally stable, weakening their impact on product pricing. Sodium silicate, soda ash, sulfuric acid and other mainstream raw materials fluctuated within a small range. Upstream manufacturers maintained steady operation with sufficient goods supply, leaving little room for major cost swings and keeping overall production costs stable. In past years, white carbon black prices largely followed raw material movements. Currently, however, the competition landscape has transformed fundamentally: basic homogeneous products compete on costs while high-end functional products compete on technology. Manufacturers of basic white carbon black, constrained by outdated processes and single product lines, can only boost sales by cutting prices relying on cost advantages. Leading enterprises equipped with modification R&D and fine production capabilities earn excess profits through product performance and customized services, and costs are no longer the core factor determining profitability.

　　The market for low-grade general white carbon black is undergoing continuous capacity elimination with mounting operational pressure. Small and medium-sized capacities are mostly concentrated on ordinary precipitated white carbon black with high product homogeneity, applied only to low-end scenarios such as common rubber goods, low-grade civil coatings, general silicone filling and regular plastic filling. Downstream traditional industries have seen weak demand recovery. End-product manufacturers keep low operating rates and only purchase raw materials as needed, showing little willingness for bulk stockpiling and resulting in slow sales. Coupled with disorderly new basic capacities launched in recent years, the low-end market is in a state of oversupply. Small and medium manufacturers keep slashing prices to seize market share, squeezing profits to critical levels. Meanwhile, tightened environmental protection and energy consumption controls raise rectification pressure on high-energy, high-emission and low-efficiency backward production lines. A large number of small factories lacking R&D, technical upgrades and quality control are exiting the market, accelerating the phase-out of low-end capacities and shifting market resources toward leading enterprises.

　　Contrary to the sluggish low-end market, high-end functional white carbon black maintains strong market heat, with booming demand driven by multiple emerging downstream sectors. In the new energy tire sector, as the penetration rate of new energy vehicles keeps rising, higher requirements for vehicle lightweighting, low rolling resistance and safety are put forward. As a key reinforcing filler for tires, highly dispersible white carbon black effectively reduces rolling resistance, improves wet grip and extends service life, becoming a core raw material for tire formula upgrading. Major domestic tire makers keep raising the proportion of white carbon black in formulas. Orders for premium highly dispersible grades remain robust, with delivery cycles for some products extended to 15–30 days, forming a stable supply shortage pattern.

　　In the advanced organic silicone industry, demand for hydrophobically modified white carbon black rises steadily. It is widely used in high-end sealants, liquid silicone rubber, thermal conductive silicone gel, electronic silicone and other products. Surface-modified special white carbon black improves tensile strength, toughness and aging resistance of silicone products, lowers system viscosity, eliminates bubbles and prevents powder precipitation, making it an indispensable reinforcing filler for premium silicone formulas. Driven by the rapid growth of electronics, new energy encapsulation, architectural sealing and smart home industries, the expansion of high-end organic silicone capacity fuels the steady demand growth of modified white carbon black. Besides, ultra-high-purity special white carbon black for photovoltaic encapsulation materials, energy storage buffer materials, lithium battery diaphragm coatings and high-end composite materials keeps capturing import substitution markets thanks to its superior dispersibility and stable batch performance, unlocking greater market potential.

　　The foreign trade pattern witnesses structural upgrading, with a clear trend toward high-end export products. The export market for conventional white carbon black is fiercely competitive. New capacities in Southeast Asia and the Middle East are put into operation, seizing the global low-end powder market with lower labor and land costs. Export prices of domestic basic white carbon black remain under pressure, export profits keep shrinking and the export share of low-end products drops year by year. On the contrary, high-end modified white carbon black, highly dispersible white carbon black and fumed silica gain rising recognition in high-end markets across Europe, America, Japan, South Korea and Southeast Asia, supported by stable batch quality, complete customized modification solutions and professional technical services. Overseas high-end buyers no longer merely compare unit prices. They pay more attention to product indicators, low-carbon certification, supply stability and technical support. Domestic high-end white carbon black achieves both import substitution and export volume growth.

　　Low-carbon production and green certification have become new market access barriers reshaping industry competition. High-end global supply chains have launched carbon footprint accounting and low-carbon access mechanisms. When selecting suppliers, European, American and multinational buyers require carbon footprint reports, production traceability records and environmental compliance certificates besides conventional physical and chemical test reports. Leading domestic white carbon black enterprises take the lead in developing solid waste recycling and low-carbon circular production processes. They use rice husk ash and industrial by-products to replace traditional mineral raw materials for white carbon black production, cutting energy consumption and carbon emissions to obtain admission tickets to high-end markets. Small and medium low-end production lines with outdated equipment, high energy consumption and no capacity for low-carbon transformation gradually lose access to high-end foreign trade and major domestic clients, further widening industry polarization.

　　In terms of technological research, the refinement, high-end development and domestic substitution of Chinese white carbon black advance rapidly. Domestic enterprises have achieved breakthroughs in core processes for previously imported ultra-pure fumed silica and nano-modified special white carbon black. They continuously innovate technologies including ultra-purification, surface activation, precise microstructure regulation and continuous synthesis, and launch special grades tailored for cutting-edge sectors such as pharmaceutical excipients, high-end cosmetics, lithium new energy, 6G high-frequency substrates, flexible sensing materials and biodegradable materials. The industry business model has been fully upgraded. Leading enterprises have transformed from simple raw material powder suppliers into formula R&D partners for downstream clients, providing one-on-one customized modification plans and full-set application technical support according to client production conditions and formula requirements.

　　Market forecast: the structural divergence of the white carbon black industry will further deepen in Q4 2026, with no overall market reversal or broad price surge. Low-end general filling-grade white carbon black will stay trapped in low-price competition with limited upside potential, while backward capacities will be phased out at a faster pace. Demand for high-end functional, modified and ultra-pure special white carbon black will remain strong. Coupled with the start of the year-end stocking cycle of downstream tire, silicone, coating and new energy enterprises in Q4, orders for high-end products may see a periodic concentrated boom. In the medium and long run, the white carbon black industry has completely left the era of capacity expansion. Future competition will center on four dimensions: functional modification technology, low-carbon green manufacturing, matching for emerging industries and customized technical services. Leading enterprises owning core technical barriers and high-end client resources will dominate the mainstream market and continuously gain industry dividends.
