6562.25 CNY per ton — that is where the spot benchmark price of PTA settled on September 7, 2026. On the surface, the daily change was flat, but stretched over a full year, this figure stands nearly 2,200 CNY above the period's minimum of 4,363.25 CNY, representing a cumulative increase of more than 50%. With prices hovering near the upper end of the annual range, the cost logic of the polyester supply chain has fundamentally shifted.
Market Context
According to public data from Shengyi She, the benchmark price at the beginning of the month was 6,303.50 CNY/ton, meaning it had climbed 4.10% in just over a week. Although the price did not rise further on September 7, its one-year position remains in the "high" zone — the maximum was 6,932.90 CNY/ton, the median 5,648.08 CNY, and the average 5,594.94 CNY. The current price is about 16% above the median and 17% above the average, indicating a significantly elevated price center.
More telling is the structure of the price range: the gap to the annual high is only 370.65 CNY, while the gap above the low is a substantial 2,199 CNY. This indicates that PTA has experienced a dramatic climb from trough to peak over the past year. Such wide fluctuations make cost control notably more difficult for polyester plants and downstream weaving mills that rely heavily on PTA.
Looking at the timeline from September 2025 to September 2026, PTA prices followed a clear pattern of initial decline followed by a sustained rally. The low range early in the period offered temporary relief to downstream enterprises, but the subsequent continuous rise gradually eroded those gains. For textile companies accustomed to low raw material costs, the current high-level consolidation signals that a new cost normal may already be here.
Industry Impact
The high PTA price first hits the polyester and polyester filament segment. Raw materials account for more than 80% of polyester production costs; every 100 CNY increase in PTA significantly compresses the profit margins of polyester plants. In the absence of explosive growth in end demand, these plants find it difficult to fully pass on cost pressures downstream, leaving them squeezed on both ends. Smaller plants with weak pricing power may even face the risk of operating at a loss.
Transmitting downward, the purchasing strategies of weaving enterprises are undergoing subtle changes. Faced with high and volatile PTA prices, fabric and weaving mills are no longer stocking up heavily; instead, they favor just-in-time purchasing and low inventory operations. This cautious sentiment is particularly evident in the grey fabric market — raw material price uncertainty makes enterprises more careful when calculating costs, and the lead time for long-term and large orders has noticeably extended.
From a cluster reaction perspective, major textile hubs such as Shengze and Keqiao are showing heightened wait-and-see attitudes. As direct downstream users of PTA, many local polyester plants have begun adjusting operating rates to cope with cost pressures, with some even choosing to replenish inventories during price pullback windows. The game between upstream and downstream is now extending from price levels to inventory management and production scheduling.
For foreign trade enterprises, high PTA prices mean greater volatility in export quotations. If raw material costs remain elevated and overseas clients show limited acceptance of price increases, profit margins will be further compressed. Conversely, if PTA prices correct sharply, orders locked in with high-priced raw materials may face inventory devaluation losses. This two-way uncertainty demands more sophisticated pricing strategies for export orders.
