The polyester chain is undergoing a new round of price pressure testing. On July 3, Rongsheng Petrochemical (including Shengyuan) reduced prices for its polyester filament FDY series products locally, with a range of 100-200 yuan/ton. Although this appears to be a routine off-season adjustment, its signal significance deserves deep exploration against the backdrop of overall pressure in the chemical fiber market: poor cost transmission from the polyester end, weak downstream weaving demand, and ongoing redistribution of chain profits.
Adjustment Details and Supply Chain Transmission
The price adjustment involves multiple conventional specifications of semi-dull FDY from Rongsheng Petrochemical, with 30D/24F quoted at 10,950 yuan/ton, 75D/36F at 8,500 yuan/ton, 150D/96F at 8,300 yuan/ton, 200D/48F at 8,450 yuan/ton, 200D/96F at 8,400 yuan/ton, and 300D/96F at 8,400 yuan/ton. From the quotation structure, the price gap between fine denier and coarse denier yarns remains significant. Fine denier yarns, due to higher process difficulty and limited capacity, maintain relatively firm prices, while coarse denier varieties are approaching cost lines.
Industry public data shows that this price adjustment has a general bearish impact on polyester FDY spot prices, with a long-short score of -1. More notably, this price reduction quickly transmits to the overall sentiment of the polyester sector, indirectly bearing on polyester staple fiber, a fellow polyester fiber category, with a long-short score of -0.5. This means that filament yarn price cuts affect not only their own variety but also suppress related futures trends through chain-wide psychological expectations.
Price Game Under Supply-Demand Imbalance
From a supply-demand perspective, the current polyester filament yarn market faces triple pressures. First, upstream PTA capacity continues to release, but cost support is insufficient, with PTA prices themselves in a weak operating range. Second, polyester plant operating rates remain high, with industry data showing polyester load around 90%, maintaining supply-side pressure. Third, the downstream weaving sector enters a traditional off-season, with weaving machine operating rates in Jiangsu and Zhejiang regions having fallen from a peak of 80% to around 70%, and terminal orders mainly consisting of small batches for just-in-time needs, lacking motivation for bulk stocking.
Rongsheng Petrochemical's price reduction is essentially a passive response to weak downstream purchasing willingness. As a domestic polyester leader, Rongsheng's price adjustments often have bellwether significance. Other polyester plants will likely follow with price cuts to maintain market share, further intensifying price competition in the polyester segment. For buyers, this round of price cuts means expanded bargaining space, but they must also be wary of the risk of further price declines.
Regional Industrial Zones and Variety Divergence
From a regional industrial zone perspective, major polyester filament production and sales areas such as Xiaoshan and Shaoxing in Zhejiang, and Shengze in Jiangsu, will be directly affected by this price adjustment. Shengze, as an important textile fabric cluster in China, has its grey fabric procurement costs highly correlated with polyester filament yarn prices. Lower filament yarn prices help reduce raw material costs for weaving enterprises, but if terminal garment orders continue to weaken, cost reductions may not translate into profit improvements and could instead trigger grey fabric price declines.
Variety divergence deserves close attention. This price adjustment mainly focuses on the semi-dull FDY series, while other varieties like DTY and POY show no significant adjustments. This indicates that polyester plants are selective in their pricing strategies: actively conceding on varieties with high inventory pressure while maintaining a wait-and-see stance on those with relatively balanced supply and demand. Buyers should adjust their procurement mix accordingly, prioritizing FDY specifications with larger price reductions while monitoring the possibility of follow-up price cuts for DTY and POY.
