Polyester Staple Fiber Quotations Diverge: Industrial Fiber Stays High, Spinning Grade Under Pressure

The polyester staple fiber (PSF) quotation sheet on June 26, 2026, reveals a striking divergence: industrial-grade fiber balls and spinning-grade staple fiber now trade at a spread exceeding 8,000 RMB/ton. The former holds steady at 15,500 RMB/ton, while the latter fluctuates between 7,250 and 7,330 RMB/ton, signaling a structural shift in downstream demand rather than a short-term fluctuation.

Industrial Fiber: Price Anchor Supported by Inelastic Demand Fiber balls (ordinary grade, 30-50mm diameter) have maintained a stable quotation of 15,500 RMB/ton, reported by Henan Kaijie Water Treatment Co., Ltd., with delivery in Zhengzhou. These products are primarily used in water treatment and air filtration, where procurement cycles are stable and substitution is difficult, resulting in extremely low price elasticity. Henan, as a major base for industrial water treatment equipment and materials, gives its quotations a benchmark effect nationwide. For industrial filter material manufacturers relying on this feedstock, the current price is at a year-high level, but no downward correction is expected in the near term due to tightening environmental standards.

Spinning-Grade PSF: Dual Pressure from Capacity Release and Weak Demand In stark contrast to industrial fiber, quotations for 1.56dtex×38mm melt-blown cotton-type PSF range from 7,250 to 7,330 RMB/ton, dominated by the Yida brand sourced from Suqian, Jiangsu. This category is the main raw material for cotton-blend yarns, making its price a direct thermometer of textile end-demand. Current quotations are 150-200 RMB/ton lower than last month, a modest but clear decline. The underlying logic: weakening cost support from upstream PTA and MEG, coupled with new PSF capacity coming online (especially via melt-blown routes), while downstream weaving and garment sectors enter the traditional off-season with low restocking appetite. Traders like Zhejiang Tianchen Textile Supply Chain report further room for negotiation in actual transactions.

Industry Implications of the Widening Spread The over-8,000 RMB/ton spread carries several messages. First, buyers must strictly distinguish pricing logic between industrial and textile grades: the former follows policy and engineering cycles, the latter tracks textile sentiment and inventory cycles. Second, for PSF mills with conversion capability, the spread may incentivize some capacity shift toward industrial grades, but equipment and process limitations constrain actual volume. Third, traders should avoid a one-size-fits-all inventory strategy: industrial fiber suits long-term contract pricing, while spinning-grade PSF should be purchased on an as-needed basis.

Regional and Channel Differences Matter Two details in the quotation sheet are noteworthy: industrial fiber quotes are concentrated in Zhengzhou, while spinning-grade PSF centers on Suqian, with highly specialized product flows in each region. The quoting entities range from water treatment companies to textile supply chain firms, indicating clear channel specialization. For downstream users, cross-regional price comparison is less meaningful than strengthening negotiation leverage within their own supply chains.

Practical Recommendations ### For Buyers - Industrial fiber procurement: Current prices are elevated, but essential purchases should not wait for a correction. Consider signing 3-6 month contracts to secure supply, focusing on Henan sources. - Spinning-grade PSF procurement: Prices still have room to decline. Maintain low inventory levels, purchase in weekly batches, and avoid large one-time stockpiling. ### For Exporters - Exporting industrial fiber balls: Domestic prices are high, increasing price sensitivity among overseas buyers. Offer differentiated specifications (e.g., modified fiber balls) to sustain margins. - Exporting PSF yarns or fabrics: Benefit from lower raw material costs boosting export competitiveness, but remain vigilant against anti-dumping risks, and prioritize markets in Southeast Asia and the Middle East.
