In August 2022, the HDPE plant of Lianyungang Petrochemical Phase II was put into operation. As of August 2022, China's PE production capacity increased by 1.75 million tons during the year. However, considering the long-term production of EVA by Jiangsu Sierbang and the extension of the second phase of LDPE/EVA plant, its 600,000 tons / The annual production capacity is temporarily stripped from PE production capacity. As of August 2022, China's PE production capacity is 28.41 million tons. From the perspective of comprehensive production, HDPE products are still the main products for capacity expansion during the year. With the continuous increase of HDPE production capacity, the competition in the domestic HDPE market has intensified, and the structural surplus has gradually emerged. Lianyungang Petrochemical and other sets of plants have been shut down for a long time or opened in stages. With the continuous increase of PE production capacity, the import and export volume of various PE varieties has also undergone relatively obvious structural changes.

From the perspective of the import volume of PE varieties from 2020 to 2022, in 2021, China's PE import volume will decrease significantly. On the whole, the PE import volume in 2021 will be about 14.5887 million tons, a decrease of 3.9449 million tons or 21.29% compared with 2020. Among them, the import volume of LDPE was about 3,059,200 tons, a decrease of 331,400 tons or 9.77% compared with 2020; the import volume of LLDPE was about 4,896,500 tons, a decrease of 1,148,800 tons or 19.00% compared with 2020; the import volume of HDPE was about 6,633,000 tons, a decrease of 19.00%. In 2020, it will drop by 2.4646 million tons, a decrease of 27.09%. Judging from the import data of various PE products in 2021, the import volume of HDPE varieties has the largest decline.

From January to July 2022, PE imports are about 7.589 million tons, down 1.1576 million tons or 13.23% from the same period in 2021. Among them, the import volume of LDPE was about 1,700,900 tons, a decrease of 128,100 tons or 7.01% compared with the same period in 2020; the import volume of LLDPE was about 2,477,200 tons, a decrease of 539,000 tons or a decrease of 17.84% compared with the same period in 2020; the import volume of HDPE was about 3,410,900 tons , a decrease of 491,500 tons or 12.59% from the same period in 2020. Judging from the import data of various PE products in 2022, due to the low price of domestic HDPE and the structural imbalance of some varieties, many domestic HDPE plants have been shut down for a long time or have been opened in stages. From January to July, China's LLDPE imports fell even more Large, followed by HDPE.

From the perspective of the follow-up import trend of PE, the current international comprehensive demand is weak. With the drop in the price of external disks, the arbitrage window for internal and external disks has opened in stages, and the intention of selling resources from the Middle East, Europe and the United States to China has increased. Since August, the import volume of PE may increase in stages. However, it is expected to remain lower than the same period in 2021 year-on-year.

From the perspective of the export volume of PE varieties from 2020 to 2022, China's PE export volume will increase significantly in 2021. Overall, the PE export volume in 2021 will be about 511,200 tons, an increase of 258,900 tons or 102.60% over 2020. Among them, the export volume of LDPE is about 153,700 tons, an increase of 7.05 tons or 84.79% compared with 2020; the export volume of LLDPE is about 79,100 tons, an increase of 42,100 tons compared with 2020, an increase of 113.46%; the export volume of HDPE is about 278,400 tons, compared with 2020 The annual increase was 146,300 tons, an increase of 110.76%. Judging from the export data of PE products in 2021, the export volume of HDPE varieties will increase the most, but the growth rate of LLDPE will be the largest.

From January to July 2022, the export volume of PE is about 436,500 tons, an increase of 121,600 tons or 38.60% over the same period in 2020. Among them, the export volume of LDPE was about 117,200 tons, an increase of 2.53 tons or 27.54% over the same period in 2020; the export volume of LLDPE was about 116,100 tons, an increase of 69,000 tons over the same period in 2020, an increase of 146.16%; the export volume of HDPE was about 203,200 tons, Compared with the same period in 2020, it increased by 27,300 tons, an increase of 15.52%. Judging from the export data of various PE products in 2022, the domestic PE export volume is still the largest in HDPE. However, due to the long-term shutdown or phased opening of many sets of HDPE plants in China during the year, the growth rate of HDPE exports is lower than that of other varieties.
