The PTA quote data from June 26, 2026, reveals a hidden rift in the chemical fiber raw material market: the same premium-grade PTA was quoted at 6,800 RMB/ton in Nantong but only 5,750 RMB/ton in Suzhou, a spread of 1,050 RMB/ton. Such a gap is almost unthinkable under normal market conditions.
This data comes from industry public quotation platforms, involving major brands like Yangzi Petrochemical, Yisheng Dahua, and Hengli Dalian. The direct cause of price divergence lies in differences in production bases and inventory strategies among traders. Nantong Zhonghe Chemical maintained a firm price for Yangzi Petrochemical's supply, while Nanjing Shuangjie Chemical offered both Yisheng Dahua and Hengli Dalian brands at 5,750 RMB/ton in Suzhou, indicating a strong willingness to destock.
Background
PTA is the core raw material for the polyester industry chain, and its price fluctuations directly impact the production costs of downstream polyester filament, staple fiber, and textile fabrics. Since the second quarter of 2026, the PTA market has experienced a transition from high levels to regional divergence. Earlier, affected by international oil price volatility and tight PX supply in China, PTA prices once surged above 7,000 RMB/ton. However, entering June, as some PTA units completed maintenance and new capacity came online, market supply gradually loosened, putting downward pressure on prices.
The price gap between Nantong and Suzhou essentially reflects two issues: first, the cost and brand premium differences among different PTA plants. Yangzi Petrochemical, as a veteran state-owned enterprise, has stable product quality and strong bargaining power in the East China market; Yisheng Dahua and Hengli Dalian, as private mega-refining representatives, have large capacity and adopt more aggressive low-price strategies. Second, regional logistics and warehousing cost differences. Nantong, as a major PTA distribution hub, has high port inventory, but local traders maintain high prices due to concentrated supply; Suzhou, being closer to downstream consumption areas, faces more competition, and traders reduce prices to win orders.
Industry Impact
For downstream polyester plants and textile enterprises, a spread of 1,050 RMB/ton means huge cost elasticity. If buyers can lock in low-priced supply in Suzhou, they can save over 1,000 RMB per ton, which is enough to determine the profit line of an order in the low-margin textile industry.
However, the price gap also signals market uncertainty. Low prices in a single region may not be a trend but a short-term behavior of individual traders. If downstream firms blindly chase low prices, they may face unstable supply or a sudden price jump during replenishment. On the other hand, if high prices in the other region persist, they will force downstream firms to shift procurement to low-price areas, accelerating price convergence.
From a longer-term perspective, regional divergence in the PTA market may become the norm under overcapacity. From 2025 to 2026, China's new PTA capacity exceeded 10 million tons, with total capacity approaching 80 million tons, while downstream demand growth slowed to below 5%. Under the supply-demand imbalance, pricing strategies among different companies and regions will become more differentiated, and low-price competition may spread from local to global.
