A new price signal has emerged in the polyester filament market: Rongsheng (including Shengyuan) Petrochemical cut its POY quotes on August 6, by 50-100 CNY/ton. Semi-dull POY 75/36 is now quoted at 8650 CNY/ton, 150/48 at 8250 CNY/ton, and black yarn 300/96 at 8850 CNY/ton. This seemingly routine adjustment, set against the current inventory and demand backdrop of the polyester chain, looks more like a proactive attempt to rebalance supply and demand.
Background
Rongsheng Petrochemical is one of the core domestic producers of polyester filament, and its price adjustments have long been regarded as a bellwether for the industry. This cut covers multiple POY specifications; although the magnitude is not aggressive, the direction is clear—the producer is trying to accelerate destocking by conceding margins. Public data shows that the spot POY market has been relatively loose recently, with downstream weavers slowing their purchasing pace, leading to rising inventory pressure at mills.
In this context, Rongsheng's move to lower quotes is essentially trading price for liquidity. For the market, this sends two signals: first, there is no tightness in POY supply; second, producers are becoming more cautious about future demand expectations. This proactive price concession often indicates that the industry is entering an active destocking phase, rather than mere seasonal fluctuation.
Industry Impact
The impact of this price cut will not be limited to Rongsheng alone. As a core player, its pricing system serves as a reference for small and medium polyester plants. In the short term, similar factories may follow suit, especially in regions where competition in POY is intense. Such coordinated price cuts will accelerate the downward shift of the industry's price center, putting periodic pressure on the spot market.
For downstream weaving and garment enterprises, falling prices mean marginal improvement in procurement costs. However, caution is needed: if demand remains weak, price declines could be a "poisoned candy"—the risk of inventory depreciation persists. Therefore, buyers should not blindly chase lows but rather formulate flexible replenishment strategies based on their order cycles and raw material inventory levels.
In the futures market, spot price adjustments are often digested in advance. POY-related futures contracts have been under pressure recently, with bearish sentiment strengthening. Historically, however, when prices approach production costs, a temporary support level often emerges. Investors should closely monitor crude oil prices and PTA trends to assess whether the cost side can provide a bottom for polyester filament prices.
