In early July, Rongsheng Petrochemical, a leading polyester producer, adjusted down its partial polyester FDY quotations by 100 to 200 yuan per ton, covering deniers from 30D/24F to 300D/96F. The semi-dull FDY 75D/36F was quoted at 8,500 yuan/ton, 150D/96F at 8,300 yuan/ton, and 300D/96F at 8,400 yuan/ton. This targeted price cut, rather than a broad reduction, has prompted a reassessment of short-term trends in the polyester chain.
Supply-Demand Logic Behind the Price Cut Industry data shows that Rongsheng's move is not isolated. Entering the second half of the year, polyester plants generally hold medium-to-high inventory levels, while downstream weaving mills remain cautious in procurement. Polyester FDY, a mainstream variety, directly reflects weaving sector operating rates and restocking sentiment. The adjusted specifications, mostly in the 30D-300D range, are widely used conventional types, indicating upstream caution on end-demand.
On the cost side, raw materials like PTA and MEG have been trading in narrow ranges, lacking upward momentum. With PX margins compressed, polyester plants are more motivated to cut prices to destock. As a bellwether, Rongsheng's pricing actions often set the tone; other polyester producers may follow, triggering a regional price downtrend.
Spillover Effects on the Polyester Sector The immediate impact is a weakening of overall market sentiment in the polyester sector. Polyester staple fiber (PSF), though not directly affected, has seen its market expectations dragged down. The PSF sentiment score has turned negative, indicating growing bearishness among traders and futures investors.
This sentiment is more visible in the futures market, where polyester FDY spot price declines have pressured related futures contracts. For textile mills, this means greater bargaining room but also higher inventory management risks—if prices continue to fall, early stockpiling could lead to losses.
Notably, the price adjustment is concentrated in the Jiangsu-Zhejiang region, home to most of China's polyester capacity. Rongsheng's plants in Xiaoshan and Ningbo set benchmarks for smaller producers. Procurement managers in weaving clusters like Shengze and Keqiao should monitor polyester plant operating rates and inventory changes closely.
Potential Impact on Weaving and Foreign Trade Lower polyester filament prices offer short-term relief for weaving mills by reducing raw material costs and improving grey fabric margins. However, whether this benefit translates into actual orders depends on demand recovery in apparel and home textiles. According to General Administration of Customs data, textile and apparel export growth has slowed in the first half, with restocking demand from European and U.S. markets falling short of expectations.
Foreign trade enterprises face more complex challenges. Exchange rate fluctuations, freight rate changes, and overseas customers' destocking cycles all delay the transmission of raw material price changes to final quotes. After polyester filament prices drop, exporters need to recalculate FOB offers, but if customers expect further declines, they may postpone orders, exacerbating order gaps.
