Some plants in East China reduced operating rates during the week. According to statistics, as of January 15, the average capacity utilization rate in the domestic acrylonitrile industry was 78.15%, down 0.67% from the previous cycle; weekly production was approximately 89,100 tons, down 700 tons from the previous cycle. PriceSeek analysis of acrylonitrile, with a long-short score: 1. The article indicates that as of January 15, the average capacity utilization rate in the domestic acrylonitrile industry decreased by 0.67% to 78.15%, and weekly production fell by 700 tons to 89,100 tons, mainly due to reduced supply caused by lower operating rates at some plants in East China. Reduced supply typically drives up spot prices, constituting a positive factor. However, the magnitude of the change is relatively small (capacity utilization rate decline is less than 1%, and production reduction is limited), not reaching a significant impact level, thus rated as a moderate positive (+1). It is expected that acrylonitrile spot prices may experience a slight increase in the short term, with attention needed on subsequent plant resumption dynamics.
