A noteworthy signal emerged in the polyester POY market in early July 2026: the price gap for the same specification and grade product across different regions in Zhejiang Province widened to 150 CNY per ton. Rongsheng Petrochemical quoted 8,200 CNY per ton, while Juxing Chemical in Shaoxing quoted 8,050 CNY per ton. This spread is not a simple promotional tactic; it reflects a deep rebalancing currently underway between upstream and downstream sectors of the industrial chain.
Industrial Implications of Regional Spreads
A 150 CNY per ton spread is uncommon for a highly homogenized product like POY. Rongsheng, based in Hangzhou, benefits from the cost advantages of its integrated refining and chemical complex, leading to a more rigid cost structure and a pricing strategy focused on maintaining margins. In contrast, Juxing Chemical in Shaoxing is closer to the downstream weaving and texturing clusters, requiring a pricing strategy that quickly responds to fluctuations in end-order demand. This means that when loom utilization rates drop or texturing margins are squeezed, POY prices in the Shaoxing production area are the first to come under pressure.
From a broader perspective, this spread can be seen as a test of regional overcapacity. The Shaoxing area is home to one of the largest chemical fiber weaving clusters in Zhejiang Province, but the continuous release of new POY capacity in recent years, coupled with slowing growth in terminal garment exports and domestic consumption, has made the supply-demand imbalance in this region more pronounced than in Hangzhou. Rongsheng's ability to maintain higher prices is supported not only by cost factors but also by its long-term contract and direct supply models, which lock in a portion of stable customers, reducing its exposure to spot market volatility.
Time-Lag Effects in Chain Transmission
As an intermediate product in the polyester filament yarn chain, POY price fluctuations typically transmit to downstream DTY and grey fabric segments within one to two weeks. The current 150 CNY per ton spread, if sustained, will directly compress the profit margins of texturing mills in Shaoxing. If these mills purchase POY at 8,050 CNY per ton while DTY selling prices remain relatively firm due to the higher-cost POY quotes in Hangzhou, Shaoxing texturing mills would temporarily enjoy a processing margin window. However, such windows usually do not last more than two weeks, as arbitrage activities across regions quickly erode the spread.
For traders, this spread provides a clear signal for cross-regional product transfers. However, practical constraints such as logistics costs, warehousing fees, and downstream customer loyalty limit the scale of arbitrage. More importantly, a widening spread often indicates that overall market liquidity is tightening—downstream buyers are reluctant to purchase, forcing mills to lower prices to attract orders.
Inventory Cycles and Procurement Rhythms
According to publicly available industry data, social inventories of polyester POY in the first half of 2026 were at moderately high levels, particularly in Zhejiang and Jiangsu provinces, where new capacity additions outpaced the recovery in end demand. The pricing divergence in early July can be interpreted as a signal that mills are actively destocking. Rongsheng's decision to maintain high prices is essentially an attempt to screen for high-margin orders, while Juxing's price cut is more focused on quickly clearing inventory and generating cash flow.
For downstream buyers, the current market environment offers two clear operational directions: first, leverage the regional spread to conduct comparative procurement, prioritizing more competitive production areas like Shaoxing; second, monitor the pace of inventory destocking. If POY inventories in Shaoxing do not decline significantly over the next two weeks, prices may further dip below 8,000 CNY per ton.
