The supply-demand balance in the acrylonitrile market is quietly shifting. On September 1, Zhejiang Petrochemical's 520,000-ton acrylonitrile unit increased its operating load to 90%. At first glance, this appears to be a single company's production adjustment, but it actually affects the pricing logic of the entire industrial chain—supply expectations are loosening, putting pressure on spot prices, while propylene, as a feedstock, gains support from increased procurement demand. Between the pressure and support, profit distribution across the chain is being reshuffled.
Supply Side: Loosening Expectations Become the Main Theme
Zhejiang Petrochemical's capacity accounts for a significant share of domestic acrylonitrile production. Recovering from a low operating rate to 90% means an additional several thousand tons of supply per month. Industry public data shows that the overall operating rate of domestic acrylonitrile plants is around 70%. This increase will further push up the industry average. For buyers, the most direct impact of increased supply is greater bargaining power; but for producers, it means rising inventory pressure, especially when downstream demand has not yet shown synchronized growth.
From a timing perspective, early September coincides with the traditional 'golden September and silver October' stocking season. The combination of increased supply and peak demand makes the market more complex. Historical experience suggests that when supply growth outpaces demand growth, prices tend to fall rather than rise. Current spot acrylonitrile prices have shown signs of weakening, with some traders offering discounts to move inventory, reflecting growing market divergence.
Feedstock Side: Propylene Gains Cost Support
The load increase directly boosted propylene procurement demand. On August 31, the main propylene futures contract 2611 closed at 8,383 yuan per ton, up 244 yuan from the previous trading day, an increase of about 3%. This price movement is not an isolated event but a reflection of the industrial chain's linkage effect—acrylonitrile plants are increasing feedstock purchases, tightening the supply-demand balance in the propylene market, and supporting prices.
For propylene producers, this is undoubtedly a positive signal. However, it should be noted that rising propylene prices will also push up acrylonitrile production costs, squeezing its profit margins. Under the dual effects of increased supply and rising costs, the profitability of acrylonitrile producers may face challenges. This price transmission along the chain will ultimately feed back into the pricing of end products such as fabrics and garments.
Industrial Impact: Transmission Chain from Monomer to Fabric
Acrylonitrile is a basic raw material for acrylic fiber and ABS resin. Its price fluctuations transmit step by step along the industrial chain. For the textile industry, the price trend of acrylic fabric is highly correlated with acrylonitrile costs. The current expectation of looser acrylonitrile supply may lead to a slight decline in acrylic fiber prices, which means eased raw material cost pressure for weaving enterprises with orders in hand.
However, transmission is not immediate. From acrylonitrile to acrylic fiber and then to finished fabric, it often takes two to four weeks. Therefore, short-term price changes are more reflected in futures and spot markets, while actual fabric quotations may lag. Foreign trade companies especially need to pay attention to this time lag to avoid blind quoting before cost changes fully materialize.
Practical Recommendations
For Buyers - Moderately slow down the procurement pace of acrylonitrile and acrylic raw materials in the short term, waiting for a price correction window brought by increased supply. - Pay attention to propylene price trends. If raw material costs continue to rise, the downside space for acrylonitrile prices may be limited, and procurement strategies need to be adjusted accordingly. - Use futures tools to hedge price fluctuation risks, especially when the spread between spot and futures widens.
For Foreign Trade Companies - Include cost adjustment clauses in quotations to avoid profit erosion due to raw material price fluctuations. - Closely monitor acrylonitrile load changes and new capacity release progress to predict fabric cost trends in advance. - Establish dynamic pricing mechanisms with upstream suppliers, linking raw material price changes to order quotations to reduce uncertainty.
In summary, the load increase at Zhejiang Petrochemical's acrylonitrile unit is a microcosm of the supply-demand rebalancing in the industrial chain. The game between supply increase and cost support will determine the price direction in the coming weeks. For industry participants, grasping the rhythm is more important than predicting specific price points.
