China PTA Operating Rate Falls to 49.3% Low Since 2014; Inventories at Historic Lows

Since late July, China's PTA industry operating rate has fallen sharply. As of August 7, the rate dropped to 49.3%, down 14.1 percentage points from the end of July, marking the lowest level since 2014. The industry's overall operating rhythm has changed significantly, breaking below the 50% threshold.

Affected by planned maintenance, typhoon weather, feedstock shortages and weak terminal demand, several companies' main production units have been forced to cut loads or halt operations. Dalian Yisheng's 3.75-million-tonne plant was shut for maintenance, a large plant in East China reduced its operating rate by 30%, and multiple plants of varying sizes in the region also cut output to varying degrees.

Tight feedstock supply is a key factor. Since late May, domestic PX units entered a concentrated maintenance cycle, with the PX operating rate at only 58.6% by end-July, down 25 percentage points from the early-May peak. The North American summer gasoline consumption season boosted aromatics blending demand, further tightening PX supply and forcing PTA producers to cut output passively.

Terminal demand remains persistently weak. Polyester filament, staple fiber and bottle chip products continued to accumulate inventory, with the polyester industry operating rate staying below 82%, a low level for the same period in recent years.

Earlier processing margins were depressed. In March-April 2026, the average PTA spot processing spread was only RMB 209 per tonne, with some periods below RMB 100 per tonne, putting heavy pressure on producers. Currently, spot and paper processing fees are stable at around RMB 500 per tonne, a relatively high level historically, with industry processing profitability improving significantly year-on-year.

The current low operating rate differs from the maintenance wave of 2022-2024. In the past three years, PTA was in a capacity expansion cycle, PX supply was ample, downstream demand showed resilience, and the minimum operating rate could be maintained at 60%-65%. Now, the expansion cycle has ended, and factors such as weak terminal orders, feedstock shortages and extreme weather have led to a passively ultra-low operating rate, with social inventories falling to historic lows for the same period.
