On August 3, the domestic acrylonitrile market received a strong signal: Jilin Petrochemical raised its listing price by 300 yuan per ton to 11,700 yuan per ton, while simultaneously taking a 130,000-ton-per-year production line offline for maintenance. With a total capacity base of 712,000 tons per year, this proactive supply reduction by a leading enterprise indicates that the short-term supply-demand balance is tilting. For industries relying on acrylonitrile—such as acrylic fiber, ABS resin, and even carbon fiber—this is not just a change in cost figures but a recalibration of supply chain rhythm.
Event Background Jilin Petrochemical's price adjustment is not an isolated move. According to industry public data, acrylonitrile plant maintenance tends to concentrate in the third quarter, but releasing maintenance news on the same day as a price hike clearly signals an intention to support prices. Among the total capacity of 712,000 tons, the shutdown of a 130,000-ton line accounts for about 18% of its total capacity, which has a significant impact on the regional supply pattern. More importantly, this combination of "price hike plus maintenance" conveys the supplier's firm attitude toward future price trends.
From a supply chain perspective, acrylonitrile sits at a critical node between propylene and downstream polymers. Upstream propylene prices have been relatively stable recently, but the proactive price increase in acrylonitrile reflects the enhanced bargaining power of the supply side. When a leading factory reduces supply through maintenance, the availability of spot market goods tightens, providing substantial support for prices. For downstream purchasers, this means rising raw material costs, which may be transmitted along the supply chain.
Industry Impact The most direct impact of the acrylonitrile price hike is in the acrylic fiber sector. As the main raw material, acrylonitrile accounts for over 70% of acrylic fiber production costs. This increase of 300 yuan per ton will directly raise raw material costs for acrylic fiber producers, compressing their profit margins. Given that downstream sectors like wool spinning and knitting are highly price-sensitive, cost pressure may eventually reflect in fabric and apparel prices. For acrylic yarn exporters, higher costs may also weaken their price competitiveness in international markets.
Meanwhile, the ABS resin industry also faces cost transmission. Acrylonitrile is one of the three monomers of ABS; its price rise increases ABS production costs, affecting procurement decisions in home appliances, automobiles, and other downstream sectors. Notably, Jilin Petrochemical's maintenance is not an isolated case. If other manufacturers follow suit with maintenance or price adjustments, the cumulative effect of supply contraction could trigger broader price linkage. Texcircle notes that acrylonitrile port inventories are currently at low-to-mid levels, providing additional momentum for price increases.
From a procurement strategy perspective, the current strong market pattern suggests that downstream enterprises should not be overly wait-and-see. Historical experience shows that price increases driven by supply-side maintenance tend to be persistent, especially when inventories are low. For acrylic fiber plants, it is advisable to lock in some raw material orders before prices rise further. For foreign trade companies, it is essential to assess the impact of cost transmission on export quotations to avoid profit erosion due to raw material fluctuations.
