The acrylonitrile market has just received a new price signal. On June 5, Sinopec North China lowered its industrial acrylonitrile ex-factory price by 100 yuan/ton to 10,300 yuan/ton. While the absolute reduction is modest, the underlying change in pricing logic deserves a closer look from the entire supply chain.
Weakening Pricing Authority: From 'List Price' to 'Market Price'
Sinopec is the dominant acrylonitrile supplier in China, and its list price has long been the benchmark for spot market pricing. The reduction in North China signals that the petrochemical giant has shifted from 'maintaining stability' to 'actively lowering prices.' Industry data shows that over the past month, spot acrylonitrile prices have already softened, with some traders transacting 50-80 yuan/ton below the list price. This adjustment is essentially a confirmation of market reality rather than an independent price discovery.
The significance of this move lies in breaking the pricing inertia that Sinopec has maintained since Q2—where list prices remained firm while actual transactions included hidden discounts. When the gap between list and spot prices is compressed, downstream buyers can access lower procurement costs without relying on traders. However, this also means that Sinopec's outlook has shifted from 'wait-and-see' to 'bearish.'
Inventory Pressure Moves Upstream: Acrylonitrile Enters a De-stocking Cycle
The direct driver of the price cut is persistently weak downstream demand. Major downstream sectors—ABS resin, acrylic fiber, and acrylamide—have all operated at lower-than-average utilization rates this year. For example, ABS plants in East China are running at 65%-70% capacity, well below the 80% breakeven point. Weak end-consumer demand has led to intermediate product inventory buildup, which in turn suppresses raw material procurement.
From an inventory structure perspective, acrylonitrile social inventories have risen for three consecutive weeks, with port stocks near year-to-date highs. Sinopec's price cut can be interpreted as a proactive 'price-for-volume' strategy—better to stimulate replenishment through concessions than let inventories pile up. The question is whether downstream mills are willing to buy. Current procurement patterns show most ABS and acrylic fiber plants are sticking to 'just-in-time' buying, with no significant increase in stockpiling. This suggests that a single list price reduction may not reverse market sentiment, and further cuts are likely.
Price Expectations and Timing: When Is the Real Bottom?
For downstream buyers, the core question is whether 10,300 yuan/ton is the bottom or just a waypoint. On the cost side, the price of propylene—acrylonitrile's main feedstock—has also weakened recently, undermining cost support. On the supply side, domestic acrylonitrile plants are running at high capacity, ensuring ample supply. On the demand side, no clear recovery inflection point has emerged in key downstream sectors.
Given these factors, the current price remains in a downward channel, with no near-term reversal in sight. The recommended strategy is to avoid bulk 'bottom-fishing' purchases. Instead, adopt a combination of 'just-in-time replenishment' plus 'forward price locking': for near-term needs, source in smaller, more frequent lots to spread price risk; for forward needs, consider futures hedging or negotiate forward pricing agreements with suppliers to lock in some costs at current levels.
