In early September 2026, China’s precipitated silica sector has officially entered the traditional September stocking cycle. The whole industrial chain, ranging from upstream raw‑material supply and plant scheduling to downstream purchasing strategies, presents a clear structural divergence. General‑grade filling precipitated silica maintains ample inventory with flat and volatile market quotations lacking upward momentum. In contrast, high‑end modified grades designed for new‑energy green tires, photovoltaic sealants, lithium‑ion supporting elastomers and electronic potting compounds have drawn surging inquiry volume and customized sample requests. Delivery cycles for tight‑supply specifications have been extended, and these premium products show far stronger price resilience than standard grades. As of September 4, the benchmark offer of rubber‑reinforcing precipitated silica stands around RMB 6100 per ton. Actual transaction prices vary slightly with order size, transportation distance and settlement terms. Low‑end filling grades remain under price pressure with thin profit margins. Ex‑factory prices of premium tire‑grade precipitated silica stay within RMB 6500‑7500 per ton, while the price gap for high‑purity fumed silica and electronic‑grade modified powder continues to widen, highlighting the premium value of high‑end products.

　　Downstream tire manufacturers have stepped into the third‑quarter production peak. Major listed tire producers have steadily lifted operating rates, prioritizing low‑rolling‑resistance tire formulations for new‑energy vehicles, which drive robust purchasing demand for high‑dispersibility precipitated silica. Export orders have also staged a phased recovery. Tire manufacturers in Europe, Southeast Asia and South America have locked in raw‑material supplies for Q3. Domestic suppliers with low‑carbon certifications, complete carbon‑footprint reports and long‑term stable batch data gain obvious advantages in overseas bidding. The silicone sealant market maintains stable performance. Demand for modified precipitated silica used in photovoltaic encapsulants, weather‑resistant construction sealants and flame‑retardant electronic sealants keeps growing moderately. Traditional segments such as coatings, shoe materials and low‑end rubber components show weak recovery. Downstream factories adopt an on‑demand replenishment strategy without large‑scale stockpiling. Insufficient demand support prevents sharp price hikes for general‑purpose precipitated silica.

　　Fluctuations in upstream raw‑material and energy costs continuously squeeze profit margins across the industry. Periodic price swings of sodium silicate and sulfuric acid, together with rigidly rising steam and electricity expenses, compress earnings for standard‑grade products. Driven by cost pressure, leading enterprises with R&D capabilities are actively optimizing product portfolios by cutting production schedules for low‑margin filling grades and allocating limited capacity to high‑value modified and tailor‑made functional silica. Meanwhile, stringent and consistent environmental supervision pushes forward upgrades including wastewater recycling, by‑salt recovery and ultra‑low‑emission renovation. These measures raise industry entry barriers. Small‑scale manufacturers face heavy capital pressure for technical transformation and limited flexibility in production adjustment. Backward and inefficient capacity is being phased out, concentrating market resources among leading players.

　　Policy shifts in overseas trade reshape the long‑term competitive landscape. The EU Carbon Border Adjustment Mechanism is being rolled out in phases. Global buyers now require full‑life‑cycle carbon emission records and green‑factory qualifications alongside conventional physical‑chemical testing during tender evaluations. Domestic producers equipped with closed‑loop water circulation and by‑product recycling facilities have built differentiated competitive edges that translate into tangible export orders. In the short run, worldwide demand for high‑quality, stable‑batch and low‑impurity functional precipitated silica maintains an upward trend. Export business delivers better profit levels than the domestic commodity market and becomes a key growth driver for premium silica sales.

　　Supply‑chain logistics and inventory cycles have also reshaped current trading patterns. After successive raw‑material volatility in the first half of the year, downstream buyers have adopted a more prudent purchasing attitude. The old model of massive centralized stockpiling has been replaced by small‑batch, frequent rolling replenishment. Distributors maintain restrained stocking and keep mid‑stream inventories at relatively low levels, leaving little room for market speculation. Major precipitated silica producers dynamically adjust finished‑goods inventory structures to guarantee supply for long‑term high‑value clients while scheduling general‑grade output according to real‑time demand. Refined inventory management mitigates extreme price swings typical of peak seasons and leads to a more rational market performance compared with previous years.

　　Looking ahead to mid‑to‑late September, the domestic precipitated silica market will continue its structural trend: flat prices for low‑end grades and firm quotations for high‑end specialty products. Sufficient supply and limited downstream demand restrict price growth for filling‑type silica. High‑performance precipitated silica serving new‑energy tires, photovoltaic new‑materials and electronic sealing materials will remain well‑supported by sustained restocking from downstream industries. Competition rules have fundamentally changed. Pricing alone is no longer the decisive factor. Batch‑to‑batch consistency, rapid formulation customization, low‑carbon compliance and comprehensive technical service packages will dominate supplier evaluation criteria. In the medium‑to‑long term, the accelerating upgrading of downstream new‑material sectors unlocks expanding market potential for functional high‑end precipitated silica. Industry value will keep shifting toward leading manufacturers with independent R&D capacity and intelligent green production lines, establishing a clear trend of high‑quality and differentiated development.
