A sharp overnight surge in international oil prices has reignited polyester cost pressures, prompting major filament producers in Shengze and surrounding areas to raise ex-works prices on September 2. POY offers increased by 50-100 yuan per ton, while certain FDY specifications jumped by as much as 200 yuan. Yet beneath the surface, downstream texturizing and weaving mills remain cautious, with operating rates trailing last year's levels and purchasing limited to essential restocking.
Cost Pass-Through and Price Structure
Public factory-gate data reveal a tiered adjustment pattern: fine-denier FDY products (40D-75D) saw uniform increases of 100 yuan per ton, while heavier counts (100D and above) rose more sharply, typically by 150-200 yuan. For instance, semi-dull FDY 100D/48F from Tongkun and Xinfengming climbed from 9,100 to 9,300 yuan per ton, a 2.2% gain, whereas 300D/144F advanced more modestly. This divergence mirrors inventory dynamics—coarse-denier items carry less stock pressure, granting mills greater pricing leverage.
The cost push originates from crude oil, but transmission is not immediate. Filament price hikes remain smaller than the rise in raw material costs, squeezing polyester producers' margins. For buyers, this rally is cost-driven rather than demand-led, amplifying the risk of chasing prices. A pullback in energy prices could quickly reverse the gains.
Weak Demand Caps Upside
Despite higher list prices, transaction volumes have not expanded significantly. Industry data indicates that operating rates at texturizing and weaving mills in Shengze and neighboring hubs are below year-ago levels, with some small factories even cutting shifts. Downstream players are digesting existing inventories, showing little appetite for fresh spot purchases. The classic 'buy on rising prices' psychology may spur some bargain hunting initially, but sustainability is questionable.
From a chain perspective, weak weaving demand will eventually pressure upstream. Although polyester plants have leveraged cost increases to raise quotes, most prioritize shipment volumes and may concede discounts in actual negotiations. The durability of current prices hinges on sales-to-output ratios over the coming weeks. If restocking fails to materialize, mills may be forced to offer concessions to maintain cash flow.
Regional Industrial Chain Reactions
As a major polyester fabric cluster, Shengze's filament price moves quickly ripple through local weaving, dyeing, and finishing segments. This round of adjustments involves leading producers across Wujiang, Tongxiang, Xiaoshan, and Shaoxing, including Tongkun, Xinfengming, and Shenghong. Their ex-works prices often serve as regional benchmarks. For garment brands and traders sourcing greige fabrics from Shengze, higher raw material costs may translate into increased fabric quotes within one to two weeks, affecting autumn order margins.
Notably, certain fully drawn bright FDY items (like 50D/24F and 108D/48F) jumped 200 yuan per ton, possibly reflecting resilient demand in applications such as faux silk and linings. Nevertheless, the pace of recovery in end-use apparel markets remains the fundamental determinant of sustained price support.
Outlook and Recommendations
In the near term, if crude oil stays elevated, polyester costs will hold firm, supporting further modest increases in filament prices. However, the medium-term trend depends on downstream demand recovery. Should weaving operating rates remain depressed, the rally lacks a fundamental basis, and correction risks accumulate.
