Viscose Staple Fiber Price Hits Three-Year High, Pressuring Downstream Supply Chain

The price of viscose staple fiber (VSF) is undergoing a rare sustained climb. According to publicly available industry data, the benchmark price of VSF 1.2D stood at 14,200 CNY/ton on June 29, 2026. This figure is not only the highest in the past year but also a three-year peak. The annual price range from June 29, 2025, to June 29, 2026, spanned 12,800 to 14,200 CNY/ton, with an average of 13,194 CNY/ton. The current price exceeds the average by approximately 7.6% and represents an 11% increase from the year's low.

Supply-Demand Dynamics Behind the High

The VSF price started the year at 14,060 CNY/ton and rose a modest 1% over six months. However, its long-term trajectory reveals that this high level is no short-term fluctuation. At 14,200 CNY/ton, the fiber has never been higher in the past 12 months and has triggered multi-cycle overbought warnings. For the textile industry, this signals increasing cost rigidity at the upstream chemical fiber level.

On the supply side, the price of dissolving pulp, a key raw material for VSF, remains firm. Meanwhile, several domestic VSF plants underwent maintenance in the second quarter, tightening market availability. On the demand side, downstream spun rayon yarn and blended yarn mills maintain high operating rates, ensuring steady offtake. This two-way support has driven prices to current highs.

Transmission Effects Downstream

As a critical raw material in the textile chain, VSF pricing directly impacts the cost structure of spun rayon yarn, air-jet spun yarn, and certain blended fabrics. At 14,200 CNY/ton, yarn mills face an additional raw material cost of roughly 1,200 CNY per ton compared to the same period last year. If this cost cannot be passed through to finished yarn prices, profit margins will come under significant pressure.

In key industrial clusters such as Xiaoshan, Shaoxing, and Changle (Fujian), some spun rayon yarn mills have tentatively raised their yarn quotes. However, downstream weaving mills are reluctant to accept higher prices, especially in home textile and apparel fabric segments, where end-order competition remains fierce. This price tug-of-war will test the resilience of the entire supply chain.

Substitution Effects and Procurement Shifts

High VSF prices are driving two market responses. First, some yarn mills are increasing the proportion of cotton and polyester staple fiber in their blends, particularly in knitted fabrics where strength requirements are moderate. Second, buyers are shifting from 'just-in-time' to 'small-lot, high-frequency' procurement to avoid catching a falling knife.

Notably, the VSF price peak has narrowed the gap with differentiated regenerated cellulose fibers like lyocell and modal. Some premium fabric buyers are evaluating switching certain orders to lyocell blends, which could reshape demand within the regenerated cellulose fiber segment in the medium term.

Practical Recommendations

For Buyers - Current prices are at historical highs. Control inventory levels and avoid bulk purchases at the peak. Consider forward contracts or phased price-locking strategies to manage cost risk. - Monitor price spreads between VSF, polyester staple fiber, and cotton. If the gap widens, evaluate increasing substitution ratios in non-critical categories. - Establish a price warning mechanism with suppliers, using weekly data from public industry platforms to time restocking during price dips.

For Mills - Incorporate raw material cost escalation clauses into yarn pricing contracts. Set up a raw material price linkage mechanism to prevent order losses from price volatility. - Optimize product mix by increasing the share of high-value differentiated products (e.g., Tencel blends, modal blends) to reduce dependence on standard VSF and improve bargaining power. - Track VSF plant operating rates and new capacity schedules to anticipate supply tightness and adjust production planning accordingly.
