Rongsheng Petrochemical's price adjustment notice on July 3 once again highlighted the chill of weak downstream demand in the polyester filament market. The company partially reduced its polyester DTY quotes by 100 to 200 yuan per ton across various specifications. DTY 75/36 low-elastic was quoted at 10,050 yuan/ton, while DTY 150/48 low-elastic stood at 9,150 yuan/ton. As a core supplier in China's polyester industry, Rongsheng's pricing actions often serve as a bellwether. This adjustment directly reflects insufficient terminal orders and rising spot sales pressure.
Industry Signals from Price Adjustments
The adjustment covered DTY products from fine to coarse denier, with reductions in a narrow 100-200 yuan/ton range, yet the signal is significant. DTY 100/96 light net was quoted at 9,900 yuan/ton, DTY 120D/192F micro net at 9,550 yuan/ton, and DTY 300/96 light net at 8,900 yuan/ton. These reductions indicate that suppliers are conceding profits under inventory pressure. Industry data shows the polyester filament market sentiment score has dropped to -1, reflecting a weak supply-demand balance. Downstream weaving mills show notably low purchasing enthusiasm, with a strong wait-and-see attitude, leading to persistently low sales-to-production ratios at polyester plants.
Notably, this adjustment is partial rather than across the board, suggesting suppliers are testing market reactions, aiming to stimulate orders with small price cuts rather than deep discounts. This strategic move reflects suppliers' cautious outlook: unwilling to compress margins through rapid price cuts, yet forced to address rising inventory.
Futures Market and Spot Linkage
The impact quickly transmitted to related sectors. On July 2, the Zhengzhou Commodity Exchange's main polyester staple fiber contract for September 2026 fell 136 yuan/ton, with a marked increase in short positions, exerting minor bearish pressure on polyester staple fiber prices. The futures market reaction indicates rising bearish sentiment among investors toward the polyester sector. This sentiment transmission is not isolated but a direct reflection of the mechanism linking upstream and downstream chains. When a core supplier lowers filament quotes, the staple fiber market is also affected by both psychological expectations and actual supply-demand dynamics.
From a broader perspective, the polyester chain is currently squeezed by weak terminal demand and capacity release on the supply side. In the first half of 2026, new domestic polyester capacity came online gradually, while textile and apparel export growth slowed, and domestic demand recovery fell short of expectations, intensifying the supply-demand contradiction. Rongsheng's price adjustment is just one concrete manifestation of this backdrop.
Impact on Each Link of the Chain
For upstream PTA and MEG suppliers, the polyester filament price cut signals potentially weaker raw material procurement demand, shifting inventory pressure from the polyester segment upward. For downstream weaving and dyeing firms, while raw material costs have decreased, the core pain point remains insufficient terminal orders. The cost reduction from price cuts may not translate into profit improvement and could instead reinforce market wait-and-see behavior, triggering a 'buy on rising, not on falling' psychology.
From a regional industrial belt perspective, weaving mills in major polyester filament consumption areas like Shaoxing, Xiaoshan, and Shengze are currently operating at 60-70% capacity, with some small firms falling below 50%. Terminal apparel brand orders are dominated by short-term, small-lot orders, lacking sustained large orders. This 'fragmented' demand structure makes it difficult for polyester plants to lower costs through scale production, further compressing profit margins.
Outlook and Strategic Responses
In the short term, polyester filament prices will remain under pressure. If terminal orders fail to show significant improvement during the traditional July-August off-season, further price cuts by suppliers cannot be ruled out. However, given current prices are already at relatively low levels, the potential for sharp declines is limited. The medium- to long-term trend depends on the pace of macroeconomic recovery and textile export performance.
For industry participants, the current phase demands greater focus on inventory management and cash flow security, rather than chasing price fluctuations.
