On March 31, 2025, the price of polyester bottle chips in the East China market fell by 30 RMB/MT to 6060 RMB/MT. The decline was driven by the drop in crude oil prices over the weekend, as well as reduced production in the polyester sector, which led to a narrow downward trend in the prices of polyester raw materials. Factories producing polyester bottle chips generally cut prices by 50 RMB/MT, causing the market center to weaken. Offers for April shipments were quoted at 6020-6120 RMB/MT, or at par to 70 RMB higher than the futures contract 05, with sporadic bids at 6020 RMB/MT. The market is shrouded in pessimism, with weak buying interest.
