Polyester Staple Fiber Price Divergence Deepens: What Is Happening to the Industry Supply-Demand Balance?

On July 3, 2026, the polyester staple fiber market displayed an extreme price divergence rarely seen in recent years: ordinary fiber balls held firm at 15,500 RMB/ton, while cotton-type polyester staple fiber quotes ranged from 6,940 to 7,320 RMB/ton, creating a gap of over 8,000 RMB. This is not a short-term fluctuation but an eruption of structural contradictions in the supply chain—conventional products are mired in overcapacity, while differentiated products enjoy the dividends of demand upgrade.

Underlying Logic of Price Divergence

Looking at the detailed quotes, the price gap within cotton-type polyester staple fiber itself is widening. For the same specification (1.56dtex*38mm, melt-spun, top grade), Zhonglei brand was quoted at 7,320 RMB/ton, Xintuo at 7,200, Yida at 7,150, and Huahong as low as 6,940. The brand gap of 380 RMB/ton exceeds normal quality premiums, reflecting differences in cost control, inventory pressure, and sales strategies among manufacturers.

Meanwhile, ordinary fiber balls remained stable at 15,500 RMB/ton, nearly double the cotton-type price. Used mainly in industrial water treatment, these high-value-added differentiated products demonstrate that downstream industrial clients have much higher willingness to pay for specialty materials than textile and apparel sectors. This "ice and fire" situation is fundamentally driven by the rigidity of demand in different application scenarios.

Impact of Regional Capacity and Logistics

The data also reveal the direct impact of regional capacity layout on prices. Zhonglei's delivery point is in Huzhou, Zhejiang; Xintuo in Xuzhou, Jiangsu; Yida in Suqian, Jiangsu; and Huahong in Wuxi, Jiangsu. These factories are located in the core Yangtze River Delta textile belt, but their price differences reflect varying cost structures—northern Jiangsu cities like Xuzhou and Suqian have lower labor and energy costs, allowing for more aggressive pricing.

Notably, Henan Kaijie supplies fiber balls from Zhengzhou at 15,500 RMB/ton. The Central Plains region is not a traditional polyester staple fiber hub, but its differentiated product positioning enables higher prices than coastal producers. This shows that for specialty products, the weight of location and logistics costs on pricing is far less than the product's own technical barriers.

Transmission Effects on Downstream Procurement and Foreign Trade

For spinners and nonwoven producers, the low price range of cotton-type polyester staple fiber means a temporary relief in raw material cost pressure. However, the brand price gap also reminds buyers: low-priced products may come with quality fluctuations or supply stability risks. Especially amid generally low operating rates in the industry, some small mills may cut prices to destock, but their future supply capability is questionable.

For foreign trade, the competitiveness of conventional polyester staple fiber exports is enhanced, but vigilance is needed against anti-dumping investigations from overseas markets targeting Chinese low-priced goods. Differentiated products like fiber balls, though high in unit price, have limited market size, suitable for foreign trade companies with specific customer resources to cultivate deeply.

Practical Recommendations

For Buyers - Prioritize suppliers with strong brand reputation and stable capacity (e.g., Zhonglei, Yida) to avoid sacrificing quality and delivery reliability for low prices. - Monitor price gap changes between brands; if the gap narrows to within 200 RMB/ton, consider increasing purchases from lower-priced brands to reduce costs. - For specialty products like fiber balls, establish long-term cooperation with professional manufacturers like Henan Kaijie to lock in price stability.

For Foreign Trade Companies - Leverage the current low price of conventional polyester staple fiber to actively expand into Southeast Asian and South Asian markets, but research target countries' tariff policies and quality standards in advance. - Position high-value-added products like fiber balls as a differentiator, focusing on industrial water treatment clients in the Middle East and Africa, who are less price-sensitive. - Monitor RMB exchange rate fluctuations and include exchange rate adjustment clauses in quotation contracts to hedge against profit erosion.
