1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The supply pressure of polyolefins remains high, with new production capacities being put into operation. The downstream is entering the end of the peak season, and the peak - season performance is below expectations. The demand in the north is decreasing, and the follow - up of orders is limited. The cost support from crude oil is weak. Although there is some boost from the anti - disorderly competition policy, the overall supply - demand pattern of plastics remains unchanged, and polyolefins have insufficient upward momentum. It is expected that the upward space of polyolefins in December is limited. Attention should be paid to the anti - involution policy. [3] 3. Summary by Relevant Catalogs 3.1. Market Analysis - The plastic operating rate has dropped to around 88%, at a neutral level, and the PP enterprise operating rate remains at around 83%, at a slightly low - neutral level. New production capacities such as ExxonMobil (Huizhou) LDPE, PetroChina Guangxi Petrochemical HDPE, and PP have been put into operation, and more are expected in December. [3] - As of the week of November 28, the PE downstream operating rate decreased by 0.39 percentage points to 44.3%, and the PP downstream operating rate increased by 0.26 percentage points to 53.83%. However, the plastic - braiding operating rate of the PP drawing downstream decreased by 0.14 percentage points to 44.1%. [3] - In November, the destocking of petrochemicals slowed down, and the current petrochemical inventory is at a slightly high - neutral level in recent years. The cost support from crude oil is limited, and it is expected that the downstream operating rate will decline in the future. [3] 3.2. Market Review - In late November, the decline of the spot price was greater than that of the futures price, and the basis of plastics decreased but remained at a slightly low - neutral level. The PP basis continued to decline slightly and was at a low level. [15][20] 3.3. Plastic Production - In October 2025, the PE maintenance volume decreased by 14.29% month - on - month to 45.63 million tons, and the PE production increased by 6.54% month - on - month to 2.8836 million tons, reaching a record high. [24] - In October 2025, the PP maintenance volume increased by 2.47% month - on - month to 776,100 tons, and the PP production increased by 4.63% month - on - month to 3.5038 million tons, also reaching a record high. [32] 3.4. Plastic Operating Rate - In October 2025, the PE operating rate increased by 1.58 percentage points to 82.01%. Recently, the plastic operating rate has dropped to around 88%. [28] - In October 2025, the PP operating rate increased by 0.94 percentage points to 77.26%. Recently, the PP enterprise operating rate remains at around 83%. [36] 3.5. PE and PP Imports and Exports - In October 2025, China's PE imports were 1.0112 million tons, a year - on - year decrease of 16.23%, and exports were 83,300 tons, a year - on - year increase of 35.42%. The net imports decreased by 18.99% year - on - year. [43] - In October 2025, China's PP imports were 273,100 tons, a year - on - year decrease of 12.16%, and exports were 235,100 tons, a year - on - year increase of 18.62%. It is expected that PP net imports will decline. [49] 3.6. Polyolefin Downstream - From January to October 2025, the cumulative production of plastic products was 65.573 million tons, a year - on - year increase of 0.5%, and the export amount was 614.55 billion yuan, a year - on - year increase of - 1.0%. [53] - As of the week of November 28, the PE downstream operating rate decreased, and the PP downstream operating rate increased slightly, but the plastic - braiding operating rate of the PP drawing downstream decreased. [57] 3.7. Polyolefin Inventory As of November 28, the petrochemical early - morning inventory was flat at 650,000 tons compared with the previous period, and was 70,000 tons higher than the same period last year. The destocking of petrochemicals slowed down in November, and the inventory is at a slightly high - neutral level in recent years. [61] 3.8. Polyolefin Profit In November, the profits of all processes of LLDPE and PP were in the red. Except for a slight increase in the profit of methanol - made LLDPE and PP, the profits of other processes declined. [65]
