For the same grade of PTA, Zibo Dehe Chemical quoted 6200 yuan/ton while Nantong Zhonghe Chemical listed 6800 yuan/ton, creating a 600-yuan spread on the same trading day. This figure far exceeds typical freight differences, signaling not just regional price fluctuation but a visible rebalancing of the supply chain.
Background
The August 4 quotes come from mainstream chemical trading platforms, involving two major brands: Yisheng Dahua and Yangzi Petrochemical. Zibo Dehe and Jiangsu Zhaohua both quoted 6200 yuan/ton, while Nantong Zhonghe and Wuhan Hengjiu quoted 6800 yuan/ton. Among the four samples, quotes from Shandong and Suzhou were notably lower than those from Nantong and Wuhan, forming a pattern of 'low center, high ends.'
Notably, the quoted brand does not always match the seller's location: Zibo Dehe in Shandong supplies Yisheng Dahua products, while Nantong Zhonghe in Jiangsu quotes Yangzi Petrochemical sources. This indicates traders are allocating goods across regions, and the spread includes logistics, warehousing, and capital costs—not just production cost differences.
From an industry perspective, a 600-yuan spread represents nearly 9% of mainstream PTA prices, enough to influence raw material procurement decisions for downstream polyester plants. Normally, regional spreads should hover around freight costs; exceeding that suggests local supply-demand imbalances or inventory pressure differences.
Industry Impact
For polyester plants, this spread means procurement strategies must shift from single-supplier to multi-region comparison. For example, Nantong has dense polyester capacity and strong raw material demand, but local quotes are high. Sourcing from Shandong or Suzhou, even with freight, could reduce costs by 300-400 yuan/ton—directly impacting marginal profits.
The divergence also reveals inventory cycle mismatches. Low prices in Shandong and Suzhou may reflect ample local PTA inventories, with traders willing to discount; high prices in Nantong and Wuhan could stem from tight spot supply or bullish expectations. If this persists, goods will flow from low-price to high-price regions, eventually narrowing the spread.
For upstream PTA producers, a widening regional spread means pricing power is shifting from factories to traders. When traders can capture excess profits through cross-region allocation, factory ex-works pricing strategies face more disruption. Over time, PTA pricing benchmarks may move from factory list prices to spot transaction averages.
Exporters should be cautious: PTA price fluctuations transmit down the chain to polyester chips, filament, and ultimately textile and apparel export costs. With global oil prices uncertain, persistent regional spreads could heighten cost unpredictability, destabilizing export quotes.
