Weekly Data Statistics on China's Acrylonitrile Production and Capacity Utilization Rate (September 18–24, 2026)

I. Qualitative Analysis of Sample Production and Capacity Utilization Trends

This week (September 18–24, 2026), the total output from Chinese acrylonitrile plants was 85,100 tons, a decrease of 4,600 tons compared to the previous week. The weekly capacity utilization rate stood at 72.96%, down 3.88 percentage points from the prior week. During this period, Shandong Haijiang suspended operations for maintenance, while Sierbang reduced its operational load again to two units running.

II. Forecast Analysis of Sample Production and Capacity Utilization Trends

Next week, the sample weekly output from Chinese acrylonitrile plants is expected to be around 84,000 tons, with a capacity utilization rate projected at approximately 72%. This represents a potential continued decline compared to current data, as Sierbang reduces its operation to two units.

III. Comparison of Sample Production/Capacity Utilization Trends with Product Prices

As of this week, sample weekly output and operating rates for Chinese acrylonitrile plants have declined. Amid cost pressures, acrylonitrile prices remained stagnant in a consolidation pattern.

Sample Description: The acrylonitrile output and capacity utilization rates reported by Chempricehub Information cover the total production of all acrylonitrile manufacturers in China, encompassing 19 domestic acrylonitrile plants, resulting in a 100% sample coverage rate.

Definitions:

• Output: Generally refers to the quantity of goods produced by manufacturing enterprises within a specific period that meet relevant standards (not merely commodity volume, but weight or volume under specific measurement units), i.e., actual production.
• Capacity Utilization Rate: Refers to the degree of utilization of an enterprise's capacity, also known as the operating load. It is generally calculated as the ratio of product output or raw material processing volume to effective capacity. (Note: At the end of each year, Chempricehub excludes capacities that have been continuously shut down for two calendar years or more from "effective capacity," classifying them as "zombie capacity" and not using them as the denominator for calculating the capacity utilization rate.)

Statistical Scope: The statistical period for Chempricehub Information's acrylonitrile output and capacity utilization data runs from Friday of the previous week to Thursday of the current week. Data is released on Thursdays at 17:00 on working days.
