Polyester Filament Price Easing: Signals from Rongsheng Petrochemical's Quotation Cut

The supply-demand balance in the polyester chain is tilting. Rongsheng Petrochemical (including Shengyuan Petrochemical) has recently lowered local quotations for polyester filament yarn by 100 to 200 yuan per ton, covering multiple semi-dull FDY specifications: 30D/24F 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. This price adjustment is not an isolated event but a necessary response to the dual pressures of cost and demand.

Industrial Background of Price Easing From the perspective of industrial chain transmission, the quotation cut directly lowers the bargaining center of the spot market. Industry public data shows that the bull-bear score for FDY has dropped to -1, indicating short-term bearish factors dominate. This price signal is not merely a corporate decision but a combined result of weakening upstream raw material cost support and sluggish purchasing willingness from downstream weaving mills. Profit margins in the polyester chain are being compressed, and Rongsheng's price adjustment is essentially a passive response to the rebalancing of supply and demand.

Transmission Effects on Related Categories The downward trend in polyester filament yarn has begun to spread to other polyester products. The bull-bear score for polyester staple fiber has also dropped to -0.5, with market sentiment clearly weakening. The logic behind this transmission is that filament yarn, as the largest volume category in polyester fiber, directly alters the purchasing expectations of traders and end-users, thereby exerting indirect pressure on related products such as staple fiber and chips. For fabric and garment companies relying on polyester raw materials, this means procurement costs may continue to decline in the short term, but it also signals that a recovery in end-user orders has not yet formed effective support.

Impact on Industrial Clusters and Foreign Trade From a regional industrial cluster perspective, inventory pressure in major polyester filament yarn production areas like Xiaoshan and Shaoxing in Zhejiang is rising. Rongsheng's price cut may trigger follow-up actions from other enterprises in the same region, leading to a round of localized price competition. For textile fabric clusters such as Shengze and Keqiao, lower polyester filament yarn prices will help reduce raw material costs in the weaving stage in the short term, but caution is needed regarding the 'buy on rising, not falling' psychology that could cause downstream buyers to delay purchases, further exacerbating inventory accumulation. On the foreign trade front, attention should be paid to price linkages in Southeast Asian markets for polyester products; if domestic prices continue to decline, export profit margins may be squeezed.

Practical Recommendations ### For Buyers - Adopt a phased procurement strategy in the short term to avoid inventory depreciation from further price declines, focusing on liquid specifications like FDY 150D/96F. - Negotiate flexible pricing agreements with suppliers to spread adjustment risks over a longer period, while leveraging spot market bargaining power for better settlement terms.

For Foreign Trade Enterprises - Closely monitor the correlation between RMB exchange rate fluctuations and polyester raw material prices, including price adjustment clauses in export quotations to mitigate contract risks from rapid cost declines. - For Southeast Asian and South Asian markets, consider moderately lowering FOB quotes to capture orders, but simultaneously assess sea freight rates and destination port inventory levels to avoid a price war.
