Daily Review: Weaker Cost Support, Polyester Bottle Chip Market Fluctuates Weakly

Market Overview: On August 29, 2025, the polyester chip market prices declined slightly within a narrow range. The average price of polyester chips in the East China region was 5,880 yuan/ton, down 10 yuan/ton from the previous working day, a decrease of 0.17%. Crude oil and polyester raw materials fluctuated weakly, resulting in poor cost support. Some polyester chip manufacturers lowered their quotes by 30-50 yuan/ton, and the actual trading focus in the market slightly shifted downward. Downstream buyers remained cautious, with purchases driven mainly by rigid demand.

Supply side: The overall operating rate of polyester bottle chips is around 76.23%.

In the upstream market: International oil prices rose overnight but turned significantly lower during the day, resulting in weak cost support. The East China PTA market slightly declined, with spot negotiation prices at 4,740 yuan/ton. The ethylene glycol market showed a narrow increase, with spot prices in the East China market around 4,530 yuan/ton.

Market Forecast: Although the United States has imposed additional tariffs on India, India disregards U.S. opposition, and the volume of oil imports from Russia in September is expected to rise, reducing supply risks. Meanwhile, after the U.S. Labor Day holiday in September, U.S. fuel demand is expected to weaken, which is unfavorable for the market. However, the uncertain Russia-Ukraine situation may provide potential support. Baichuan Yingfu predicts that in the short term, international crude oil futures prices may fluctuate weakly, with poor support from the cost side. The willingness of downstream and end-users to stock up is lacking, with purchases made as needed. The supply and demand pattern is expected to remain in a stalemate, and the polyester bottle chip market is predicted to fluctuate slightly weakly in the short term, with market price fluctuations in the East China region ranging from 5,800 to 5,950 yuan/ton.
