On June 26, 2026, public quotations for polyester FDY 150D/96F semi-dull yarn ranged from RMB 8,500 to RMB 8,750 per ton, with a spread of RMB 250/ton among six major producers in Zhejiang Province. This seemingly routine price list reveals deeper structural changes in the polyester filament market: diverging cost support, varying capacity utilization, and regional rebalancing of downstream weaving demand.
Cost Transmission and Capacity Utilization Divergence
From the raw material side, PTA and MEG account for over 80% of polyester FDY's direct costs. Recent maintenance schedules in the PX-PTA segment have tightened spot supply, but differences in the level of integration across polymerization units have led to significant variations in raw material procurement costs among companies. Rongsheng Petrochemical and Tongkun Group, both with full industry chains from PX to polyester, quoted RMB 8,500/ton and RMB 8,750/ton respectively. This difference likely reflects their product mix strategies: the former may prioritize volume pricing and lock in large downstream clients, while the latter may maintain a premium due to a higher share of differentiated products.
Zhejiang Tiansheng Chemical quoted RMB 8,710/ton, in the upper-middle range, while Jiabao Fiber and Juxing Chemical quoted RMB 8,510/ton and RMB 8,500/ton respectively, near the bottom. This spread is not accidental: Tiansheng's facilities are mostly newer melt-direct spinning lines offering high quality stability but also higher fixed cost amortization; other producers like Juxing may be compressing unit costs by adjusting spinning speeds or using chip-spinning ratios to gain price competitiveness.
Regional Weaving Demand Rebalancing
The delivery locations on the quotation list are concentrated in Hangzhou and Shaoxing, two major polyester industrial clusters. This is no coincidence. Shaoxing, as one of the world's largest chemical fiber fabric production bases, sees its circular knitting and water-jet loom operating rates directly impact FDY procurement rhythms. Since Q2 2026, some small-to-medium weaving enterprises in Shaoxing have reduced operating loads due to the outflow of final garment orders to Southeast Asia, leading to a phased contraction in demand for standard FDY specifications. Conversely, weaving clusters around Hangzhou, focused on home textiles and industrial textiles, have maintained resilient FDY procurement due to stable domestic demand from infrastructure and automotive interiors.
This asymmetric regional demand explains why the same product specification carries different prices at different delivery locations. Producers in Shaoxing, such as Juxing and Jiabao, may be offering lower prices to clear local inventory, while those in Hangzhou, like Rongsheng and Tongkun, maintain firmer quotes reflecting more stable customer bases and stronger bargaining power.
Q3 Supply Expectations and Price Outlook
Looking ahead to Q3 2026, the maintenance schedule of the polyester chain will be a key variable affecting FDY prices. Following historical patterns, July-August is typically a peak season for PTA plant turnarounds, which could tighten PX-PTA supply and push up the cost base of polyester filament. However, current downstream weaving mills hold raw material inventories at a low 7-10 days. If maintenance expectations materialize, it could trigger a round of restocking, driving FDY prices toward the upper end of the current range.
On the supply side, new capacity additions add pressure. In the first half of 2026, China added approximately 2.8 million tons/year of new polyester capacity, with FDY accounting for about 35%. These new lines, mainly in Zhejiang and Jiangsu, will directly impact market supply as they ramp up. If new capacity floods the market in the second half of the year, even with rising costs, FDY price gains could be capped by increased supply, creating a scenario of 'cost-push but limited upside'.
