On July 3, 2026, Rongsheng Petrochemical (including Shengyuan) partially reduced its polyester filament yarn quotes by 100-200 CNY/ton, covering multiple DTY specifications such as 75/36, 100/96, 120/192F, 150/48, 150/96, and 300/96. As a core supplier in the polyester industry, this price cut signals weak end-order support and rising spot sales pressure, exerting a generally bearish impact on polyester DTY and filament spot prices. The PriceSeek multi-bearish score of -1 for polyester filament indicates a clear downward bias.
Background
The adjustment focused on the polyester DTY category, with a 100-200 CNY/ton reduction. For instance, 75/36 low-elastic yarn was quoted at 10,050 CNY/ton, 150/48 at 9,150 CNY/ton, and 300/96 at 8,900 CNY/ton. This partial rather than across-the-board cut suggests the company is testing market response rather than engaging in a full clearance. Such "point-based" price reduction is common in downturns, aiming to stimulate sales of specific specifications without triggering widespread panic.
Industry Impact
Polyester filament is a midstream core product in the chemical fiber chain; its price changes quickly transmit to downstream weaving, dyeing, and apparel sectors. This adjustment sends three key signals:
First, end demand is indeed weakening. July 2026 is a traditional off-season for textiles, compounded by global consumer uncertainty. Downstream weaving mills are reluctant to purchase, and Rongsheng's move is a passive response to the "buy on rising, not falling" mentality.
Second, the polyester staple fiber market is under simultaneous pressure. On July 2, the main PSF futures contract (2609) on Zhengzhou Commodity Exchange fell by 136 CNY/ton, with significantly increased short positions. PSF and filament share raw materials, creating a notable sentiment contagion. The PSF multi-bearish score of -0.5, while slightly better than filament, still indicates a downward trend.
Third, the inventory cycle may be entering an active destocking phase. If end orders do not recover in July-August, upstream producers may further cut prices, potentially sparking a new round of price wars. For weaving mills relying on filament purchases, this presents both a cost-reduction opportunity and a warning of shrinking orders.
Practical Recommendations
For Buyers - Adopt a just-in-time procurement strategy: Prices are in a downward channel with no clear bottom yet. Maintain 1-2 weeks of safety stock to avoid inventory losses. - Monitor the DTY/FDY price spread: If DTY falls more than FDY, consider adjusting procurement mix to favor more cost-effective specifications. - Utilize futures tools: Although filament lacks direct futures, hedge raw material price volatility through PTA and MEG futures.
For Foreign Trade Firms - Shorten quotation validity: During volatile periods, reduce offer validity from the usual 7-14 days to 3-5 days to avoid dual hits from price and currency fluctuations. - Watch Southeast Asian competitors: Rongsheng's price cut may expand China's export price advantage, but be wary of simultaneous price reductions by Vietnam, India, and others. - Lock in forward orders: If foreign buyers accept long-term contracts, try to fix delivery prices for August-September, leveraging current low costs for stable margins.
Overall, this adjustment signals a shift from "high-level stalemate" to "weakness and adjustment" in the industry. All links in the textile chain need to reassess inventory strategies and price expectations to prepare for second-half uncertainties.
