In 2021, the domestic acrylonitrile market price rose first and then fell. From February to March, it rose rapidly, reaching 5000 yuan / ton, and the high point was 16500 yuan / ton in mid March. After that, the price gradually fell, but basically remained above 14000 yuan / ton. In terms of stages, the domestic acrylonitrile market price fluctuated little in January, remained at 11500 yuan / ton, and the fundamentals were relatively balanced. Since February, the price has been significantly higher. On the one hand, the supply of overseas units has been tightened due to force majeure, and the domestic export demand has increased. On the other hand, the expectation of domestic and foreign unit maintenance in the second quarter has also stimulated the market bullish. In addition, the downstream demand has increased. With the superposition of various favorable factors, the price of acrylonitrile has been significantly higher, and the rise has continued until mid March.

Since late March, the price of acrylonitrile has dropped rapidly. On the one hand, the maintenance plan of some enterprises under high profits has been delayed, the manufacturers have high production enthusiasm, and Haijiang has also restarted production; On the other hand, the resistance of downstream acrylic fiber and amide industries has increased. After entering the second quarter, the price of acrylonitrile basically fluctuated between 14000-15000 yuan / ton, with a short period of lower 14000. Although the overseas units recovered in April, the arrival time of far foreign goods in the Asian market was in late June, so the domestic acrylonitrile export volume was still considerable in the whole second quarter. In addition, the demand of downstream ABS and other industries is stable, which supports the high operation of acrylonitrile price.

In the third quarter, although the new production capacity of Zhejiang Petrochemical phase II was released, its products were not fully released until October due to logistics problems. In addition, during this period, Sri Lanka and Shanghai Secco and other units frequently had unplanned maintenance, the supply also decreased, and the export demand remained stable, thus supporting the acrylonitrile price to remain at a high level between 14500-15500 yuan / ton. In October, due to the influence of double control, Sri Lanka halved its operation, while Zhejiang Petrochemical products were released, so the supply and demand maintained a balanced performance. From November to December, new production capacities such as kruer phase II and lihuayi were released one after another, and the price began a new round of decline.

According to data statistics, the average price of acrylonitrile products in 2021 was 14302 yuan / ton, an increase of 5410 yuan / ton or 60.8% compared with 8892 yuan / ton in 2020. The annual lowest price of 11400 yuan / ton appeared in mid January, and the highest price of 16500 yuan / ton appeared in mid March. As of October 31, 2021, the mainstream transaction price of acrylonitrile products in East China is 15000 yuan / ton, an increase of 5700 yuan / ton or 61.3% compared with 9300 yuan / ton in the same period in 2020.
