On the same day, for the same grade and the same mainstream supply source, PTA quotes across three provinces differed by 1,000 yuan per ton. Within the polyester chain, that is no longer a simple regional price gap — it signals a layered pricing mechanism.
The Spread Structure: Regional Logic Behind the Numbers
Industry public data shows premium-grade PTA quoted at 7,800 yuan per ton in Zibo, 6,800 yuan per ton in Wuhan, and 7,100 yuan per ton in Suzhou. Three quote points and two mainstream supply routes form the most direct regional spread map of the day.
Notably, the Suzhou market receives premium-grade material from both Yisheng Dalian and Hengli Dalian, with both quoted at 7,100 yuan per ton. This means that in East China's main consumption hub, brand premium has been compressed to near zero. The core variable of price competition has shifted from "who produced it" to "who can deliver faster."
Zibo's quote is significantly higher than Wuhan's, and the reason is not hard to judge: Shandong's local polyester capacity is relatively limited, with supply heavily reliant on external inflows, extending the logistics radius and raising delivered costs. Wuhan sits in central China, absorbing supply from both East and Central China, facing more intense competition and thus lower quotes.
For buyers, the judgment is direct: PTA's delivered price is no longer determined by a single production region's quote, but jointly priced by delivery warehouse locations, transport distance, and local polyester operating rates.
Industrial Transmission: Who Pays for the Spread
The widening spread pressures not traders first, but small and medium-sized polyester plants and spinning enterprises. Large polyester groups typically have long-term contracts and proprietary logistics, limiting the impact of regional spreads. But smaller plants rely on spot procurement, and once their purchasing radius crosses provinces, a 1,000 yuan per ton spread can swallow the thin margins of processing.
From a chain transmission perspective, a widening PTA spread typically decays along the path of PTA → chips → filament/staple fiber → weaving. The further downstream, the lower raw material cost proportion, but the weaker the bargaining power of small and medium weavers, who can only passively accept upstream transmission.
Another easily overlooked variable is regional arbitrage. When the Zibo-Wuhan spread remains at a high level, traders' incentive to move goods across regions strengthens, which in turn compresses the spread. But arbitrage requires controllable logistics costs. If freight rises, the arbitrage window closes quickly, and the spread instead solidifies.
For export-oriented textile firms, regional raw material cost differences indirectly affect quote competitiveness. For the same order, a factory sourcing from Wuhan and one sourcing from Zibo start from different cost baselines, naturally leading to differentiated export quotes.
Trend Judgment: Pricing Power Is Becoming Multi-Point
For a long time, PTA pricing relied heavily on East China's main ports and futures主力 contracts, with spot quotes fluctuating around a single center. But the current widening of regional spreads indicates pricing power is dispersing from a single center to multiple regional nodes.
This dispersion is not necessarily bad. For the market, multi-point quotes mean more thorough price discovery and less room for manipulation of a single quote. But for buyers, information costs rise — looking at only one quote point can easily lead to wrong decisions.
In the short term, whether regional spreads converge depends on two variables: whether logistics freight falls, and whether polyester operating rates across regions become more balanced. If neither improves, spreads are likely to remain volatile at high levels.
In the medium to long term, as polyester capacity in central and western China is gradually commissioned, localized supply capacity in Central China, Northwest China and other regions will strengthen, and regional spreads are expected to narrow gradually. But before that, cross-regional procurement will remain a necessary means for small and medium textile firms to control costs.
