Daily Review: Cost Support Still Present, Polyester Bottle Chip Market Edges Higher

Market Overview: On June 11, 2026, prices in the polyester bottle chip market edged up slightly. The average market price of polyester bottle chips in East China was RMB 8,230/ton, up RMB 30/ton from the previous working day, representing an increase of 0.37%. Crude oil supported an upward trend in polyester feedstock prices, and some polyester bottle chip producers raised their quoted prices by RMB 50–100/ton, pushing the market’s actual transaction center higher. However, downstream buyers mostly remained on the sidelines, chasing the rally cautiously, and trading was sluggish.

On the supply side, the overall operating rate of PET bottle chip is around 76.04%.

Upstream market: International oil prices remained at a high level during the day, with ongoing support from the cost side. The East China domestic PTA market fluctuated on the firmer side, with prices around RMB 6,585/ton. The ethylene glycol market rose sharply, with East China spot prices at around RMB 4,745/ton.

Market outlook: The United States has launched a new round of airstrikes against Iran, and geopolitical tensions in the Middle East remain elevated, providing a risk premium to the market. U.S. crude oil inventories fell sharply last week, while global crude inventories are being drawn down, reinforcing expectations of tight short-term supply. International oil prices are expected to remain relatively strong in the near term, with continued support from the cost side. However, downstream restocking expectations at high price levels are low, and trading is largely maintained on a need-to-buy basis. With both bullish and bearish signals present, the polyester bottle chip market is expected to fluctuate in the short term, with market prices in East China likely to range between RMB 8,100 and 8,400 per tonne.
