The acrylonitrile market received a clear pricing signal in mid-July. Sinopec East China Sales Company raised its listing price by RMB 200/ton to RMB 9,800/ton, with Zhenhai Refining and Anqing Petrochemical implementing the same price. This move systematically lifts the spot quotation benchmark, rather than being a one-off fluctuation.
For the textile and chemical fiber industry, acrylonitrile is a core raw material for acrylic fiber, ABS resin, and even carbon fiber. Its price changes cascade down the supply chain, ultimately affecting fabric costs and end-user procurement decisions. Although the adjustment is not drastic, its timing in mid-year, coupled with seasonally weakening downstream demand, gives it significance far beyond the numerical change.
Pricing Mechanism and Regional Concentration
Domestic acrylonitrile capacity is highly concentrated among a few petrochemical groups, with Sinopec East China being a core supplier in the region. Zhenhai Refining and Anqing Petrochemical together account for nearly 60% of East China's capacity, and their listing price effectively anchors the spot market. Before this adjustment, sporadic price hikes by traders lacked authoritative backing. Sinopec East China's move provides official endorsement for the upward trend.
Historically, Sinopec East China's listing price adjustments lag behind the spot market by one to two weeks, but once established, they drive the entire industry's quotations upward. After this adjustment, refineries in Shandong and other parts of East China are likely to follow, pushing the spot trading range from RMB 9,600-9,700/ton to RMB 9,800-10,000/ton in the short term.
Downstream Transmission and Procurement Rhythm
For acrylic fiber producers, raw material costs account for over 70% of total expenses. Every RMB 200/ton increase in acrylonitrile raises theoretical production costs by about RMB 140-160/ton. Given weak downstream demand for spinning, blankets, and other end uses, companies find it difficult to fully pass on costs. This will further squeeze profit margins in the acrylic fiber segment, potentially forcing small and medium factories to reduce operating rates or switch to alternative raw materials.
In the ABS resin sector, the situation is similar. Acrylonitrile accounts for 15-20% of ABS composition, but with slowing demand from appliances and automotive sectors, ABS producers face rising inventory pressure. Higher raw material costs will erode processing margins, prompting companies to delay procurement or increase imports.
The carbon fiber industry follows a different logic. Although acrylonitrile costs are high, carbon fiber products have high added value and strong customer stickiness, allowing smoother cost pass-through. However, rapid domestic capacity expansion limits incremental acrylonitrile demand from new production lines, making sustained upward pressure unlikely.
Foreign Trade Expectations and Substitution Effects
This price adjustment occurs against a backdrop of heightened RMB exchange rate volatility. The gap between domestic and imported acrylonitrile may narrow. Currently, CFR prices from South Korea and Taiwan are around RMB 9,500-9,600/ton, slightly below domestic levels after tax. If domestic prices continue to rise, downstream companies may increase imports, putting substitution pressure on local supply.
On the other hand, exports of downstream products like acrylic fiber and ABS face uncertainty. Anti-dumping investigations against petrochemical derivatives in European and American markets are increasing, with some orders shifting to Southeast Asia. Higher raw material costs further weaken the export competitiveness of domestic processors, forcing foreign trade companies to reassess their forward contract locking strategies.
