Report Industry Investment Rating - Unilateral: Neutral; Inter - period: None [3] Core View - The recent 90 - day tariff suspension agreement between China and the US has continued the positive impact of tariff policies, leading to a continuous increase in the polyolefin futures prices. Propane prices have declined, but the production profit of PDH - made PP remains significantly in the red. Multiple new PDH units have been shut down for maintenance, and the restart time is undetermined. There is an expectation of rising PDH costs in the future. The new facility of Huizhou ExxonMobil has increased production. Among the existing facilities, the number of PE shutdown units has increased, with a slight decrease in the operating rate, while the PP operating rate has increased, resulting in significant supply pressure in the polyolefin market. Polyolefin producers have accumulated large inventories and face great pressure to reduce stocks. Downstream demand is weak, with fewer new orders. The operating rate of the agricultural film industry has seasonally decreased, while the operating rates of other industries are stable, mainly for rigid - demand purchases [2] Summary by Directory 1.
