China Polyester Bottle Chip Market Shows Volatility with Upward Bias and Slight Gains on July 7

I. Drivers of the Rise: A Combination of Cost Stabilization and Supply Contraction Leads to a Periodic Price Recovery

The current rebound in PET bottle chip prices is primarily driven by the dual support of marginal improvements in costs and a contraction in raw material supplies. Coupled with the emit of essential downstream restocking demand stimulated by low prices, market sentiment has seen a temporary recovery.

1. Crude Oil Stabilizes at Low Levels; Cost-Side Drag Eases

International oil prices found temporary support after the geopolitical risk premium was priced out, acting as the immediate trigger to the bottle chip rebound. Following the US-Iran peace agreement, shipping traffic through the Strait of Hormuz gradually resumed, and Brent crude prices fell rapidly to the $70/barrel mark, efficiently absorbing the pre-conflict geopolitical premium. Currently, the market is focused on the progress of follow-up US-Iran talks; combined with a weakening US dollar, oil prices have edged upward. The downward pressure on PET prices from the cost side has been temporarily lifted, allowing market sentiment to recover. PTA supply has contracted sharply, strengthening support from the raw material side.

2. Supply Contraction Driven by Concentrated PTA Maintenance Provides Solid Cost Support to Bottle Chips

On July 6, the domestic PTA capacity utilization rate fell by 2.68% month-on-month to 52.35%. A extensive PTA unit in East China with an annual capacity of 2.5 million tons was shut down to maintenance. Concentrated maintenance by major producers has led to a significant tightening of market supply, and social inventories continue to decline. According to Guosen Futures, downstream PET operating rates have remained stable; combined with concentrated maintenance of PTA vegetation, the improved supply-demand stability has driven a modest rebound in futures prices. Meanwhile, the PX sector has entered a destocking cycle; with concentrated maintenance across Asia and China in July leading to a month-on-month decline in sector operating rates, the simultaneous destocking of both PX and PTA has solidified price support to PET bottle chips from the raw material side.

3. Low-price effect emerges; downstream restocking demand sees moderate emit

Following a sustained decline, PET prices have fallen by over 2,000 RMB/tonne from their April peak, entering a range acceptable to downstream buyers and gradually stimulating restocking interest. Last Friday, major soft drink manufacturers launched their August tender cycles, leading to a warming of trading sentiment in the bottle chip market this week and an improvement in export shipments. On the morning of July 6, sporadic transactions in the East China market were recorded at 6,930–6,990 RMB/tonne, driven primarily by essential restocking needs. However, downstream willingness to chase rising prices remains weak, with limited firm bids; demand is still characterized by essential, need-based purchasing.

II. possible Pressure: Persistently loose supply limits upside possible

Despite the immediate price recovery, supply-side pressure on PET bottle chips continues to build. Factors such as plant restarts, the emit of new capacity, and high inventory levels are constraining the extent of the price rebound.

The sector currently sees greater plant restarts than maintenance shutdowns, leading to increasingly ample supply: Zhejiang Tiansheng has raised the operating rate of its 400,000-tonne bottle chip unit, while Sichuan Hanjiang (600,000 tonnes) and Shandong Fuhai (300,000 tonnes) have restarted operations and resumed feedstock input. Coupled with expectations to the restart of long-idled units and plans to new capacity to come online, market supply is set to increase further. While there have been some maintenance-related disruptions—such as the shutdown of Central China’s Anhua unit (300,000 tonnes) in late June due to environmental inspections (with a restart planned to late July) and the maintenance of South China’s Yisheng Hainan unit (750,000 tonnes) in early July (restart date pending)—the capacity being restarted far exceeds the capacity undergoing maintenance, leaving the sector's loose supply landscape unchanged. Meanwhile, inventories at PET chip vegetation continue to build up, with some companies seeing a steady, albeit slight, rise in stock levels. Compounding this, rising ocean freight costs are hampering export shipments; the resulting headwinds in the export sector further exacerbate inventory pressure at vegetation, continuing to weigh on prices.

III. Market Outlook (Mid-July)

Short term (1–2 weeks): Prices are expected to fluctuate within the 6,800–7,100 RMB/tonne range, with little likelihood of a significant, sustained rally or sharp decline.
