Polyester FDY Prices Show Regional Divergence, Zhejiang Chemical Fiber Chain Faces New Game

Between 8,500 yuan/ton and 8,750 yuan/ton lies only the province of Zhejiang. The public quotes for polyester FDY (150D/96F, AA grade, semi-dull) on June 26, 2026, reveal a widening price gap among Zhejiang's chemical fiber enterprises. Rongsheng Petrochemical and Zhejiang Juxing Chemical Fiber quoted 8,500 yuan/ton in Hangzhou and Shaoxing, respectively, while Tongkun Group in Hangzhou was 250 yuan higher at 8,750 yuan/ton. This is not a statistical error but a real game involving different inventory levels and operational strategies.

The Industrial Logic Behind Price Divergence

A 3% price difference for the same specification, grade, and region is unusual for bulk chemical fiber varieties like polyester FDY. Typically, FDY prices are highly synchronized due to raw material cost support from PTA and MEG. However, the current divergence signals that cost-side transmission is weakening, replaced by individual corporate strategies.

• The 8,500 yuan/ton quotes from Rongsheng and Juxing suggest urgent destocking needs, likely due to high inventory pressure or bearish market outlook.
• Tongkun's 8,750 yuan/ton sends the opposite signal: strong order books, manageable inventory, or higher cost structures from raw material procurement timing.
• Zhejiang Tiansheng's 8,710 yuan/ton and Kaishi Group's 8,650 yuan/ton occupy the middle ground, reflecting flexible pricing strategies.

For downstream weaving mills, this divergence means that purchasing windows are no longer uniform. For the same order, picking up goods in Hangzhou versus Shaoxing could result in a cost difference of over 200 yuan per ton. For mills consuming thousands of tons annually, this translates directly into hundreds of thousands of yuan in profit swings.

The Supply-Demand Balance Is Shifting

Behind the price divergence lies a subtle shift in supply-demand dynamics. In the first half of 2026, as domestic PTA capacity continued to expand, raw material costs remained relatively loose. However, recovery in downstream textile and apparel demand fell short of expectations, leading to inventory accumulation in the intermediate segment—polyester filament yarn.

Regionally, Shaoxing and Hangzhou, as hubs of chemical fiber clusters, host many small and medium-sized weaving mills with high price sensitivity, forcing local fiber producers to cut prices first to maintain volume. In contrast, Tongkun Group, as an industry leader with an integrated chain (from PTA to polyester filament yarn) and larger capacity, enjoys stronger pricing power and inventory buffers, allowing it to sustain higher prices.

This is essentially a redistribution of profits within the industry chain. The risk of price wars among fiber producers is rising, but leading companies may leverage their cost advantages to actively cut prices and squeeze smaller competitors, thereby accelerating industry consolidation.

Practical Recommendations

For Buyers - Monitor regional price spreads and prioritize sourcing from lower-quoted areas like Shaoxing and Hangzhou, but verify supply stability and logistics costs. - Use competitive bidding: seek quotes from both Rongsheng and Tongkun, using the 250 yuan/ton spread as a bargaining chip to negotiate a middle price. - Build inventory buffers: if current prices are relatively low for the year, consider increasing safety stock to hedge against potential cost increases from leading producers' price adjustments.

For Exporters - Include price adjustment clauses in contracts: given increased FDY price volatility, stipulate in export contracts that unit prices can be renegotiated if raw material costs change by more than a certain threshold (e.g., 3%). - Lock in forward procurement: sign short-term framework agreements with lower-priced suppliers to lock in costs around 8,500 yuan/ton, avoiding cost rebounds after the price war ends. - Monitor exchange rates and export tax rebate policies: if RMB volatility combines with raw material price hikes, export margins may be squeezed; hedge in advance using financial instruments.
