Polyester Staple Fiber Price Falls Below 7300 RMB/Ton: One-Year Data Signals Industry Adjustment

The price trajectory of polyester staple fiber is sending a clear signal to the market: the industry's supply-demand landscape is undergoing a mild but persistent reshaping. As of July 3, 2026, the benchmark price of this key chemical fiber variety has dropped to 7280.83 RMB/ton, down 1.86% from the beginning of the month, with a single-day decline of 0.42%.

Price Center Shifting Downward

From a full-year perspective, the current price sits at the median level of the one-year range. Over the past 12 months, the highest price for polyester staple fiber was 8426 RMB/ton, the lowest was 6267 RMB/ton, and the median was 7346.6 RMB/ton. This means the current price is slightly below the median, with a gap of 1145 RMB/ton from the top and 1013 RMB/ton from the bottom. The annual average price of 6966.99 RMB/ton further confirms the downward shift of the price center.

For textile companies, this below-median price level means a temporary relief in raw material cost pressure, but also hints at insufficient support from downstream orders. The operating rate and inventory levels of chemical fiber plants are usually closely linked to price trends, and current data suggests the industry may be entering an active destocking phase.

Ripple Effects Along the Supply Chain

Polyester staple fiber is a key raw material for spinning, nonwovens, and filling materials. Its price fluctuations quickly transmit to downstream yarn, fabric, and even garment sectors. From the industrial cluster response, traders in chemical fiber hubs like Shengze and Changxing generally report a decline in inquiry activity, with actual transactions mostly consisting of small orders for immediate needs. This change in purchasing rhythm essentially reflects a lack of confidence in the end-consumer market.

International crude oil price volatility indirectly affects polyester staple fiber costs through the PTA (purified terephthalic acid) link. In the first half of 2026, the crude oil market experienced wide fluctuations, providing no clear cost support for chemical fiber raw materials. Meanwhile, the slowdown in China's textile and apparel export growth further weakened the pulling force from the demand side.

Impact on Procurement and Inventory Strategies

The current price range offers a relatively safe window for buyers. Considering that the annual price fluctuation exceeds 2000 RMB/ton and the current price is still about 1000 RMB away from the historical low, moderate opportunistic replenishment is reasonable. However, large-scale stockpiling should be approached with caution, as if downstream demand continues to weaken, prices could move further toward the bottom.

For chemical fiber plants, profit margins are being squeezed. Under the dual pressure of raw material costs and product selling prices, some small and medium-sized capacity may face shutdown or production reduction pressure. Industry concentration is expected to further increase, and large enterprises with scale advantages and cost control capabilities will be more resilient.

Practical Recommendations

For Buyers - The current price is at a below-median level; consider moderately increasing safety stock, but avoid exceeding two months' supply to guard against further price declines. - Monitor PTA and crude oil price trends; if cost-side prices rebound significantly, accelerate procurement pace. - Prioritize signing long-term contracts with large chemical fiber plants to lock in price ranges and hedge against short-term volatility.

For Foreign Trade Companies - Build price fluctuation flexibility into export quotations; consider adopting a monthly price adjustment mechanism. - Monitor price differentials in Southeast Asian and South Asian markets; current domestic prices are at a mid-low level internationally, which may attract some overseas orders back. - Lock in logistics costs with shipping lines in advance to avoid freight fluctuations eroding already thin profit margins.
