On July 3, 2026, Rongsheng Petrochemical (including Shengyuan) implemented localized price reductions for multiple specifications of its polyester DTY, with cuts ranging from 100 to 200 yuan per ton. Key specs include 75/36 low-elastic at 10,050 yuan/ton, 150/48 low-elastic at 9,150 yuan/ton, and 300/96 low-elastic at 8,900 yuan/ton. As one of the core suppliers of polyester filament in China, Rongsheng's pricing moves are often seen as a bellwether.
Background: Weak Supply-Demand Dynamics Signal Convergence
This price cut did not occur in isolation. On the previous day, July 2, 2026, the main polyester staple fiber contract (2609) on the Zhengzhou Commodity Exchange fell by 136 yuan/ton, with a notable increase in short positions. The bearish sentiment in the futures market resonated with the spot price easing, collectively pointing to the weak end-demand pressure currently facing the polyester chain.
According to industry public data, the polyester DTY bull-bear score has dropped to -1, the overall polyester filament score is also -1, and the polyester staple fiber score stands at -0.5. The widespread negative scores indicate that market expectations for short-term price trends have shifted from cautious to bearish. The core driver is the persistently insufficient purchasing enthusiasm from downstream weaving and texturing mills, coupled with rising spot inventory pressure and accelerating stock accumulation.
Industry Impact: Transmission Chain from Filament to Staple Fiber
Rongsheng's price adjustment directly impacts the polyester DTY spot market. Following the reduction, other suppliers in the same region face pressure to follow suit, potentially lowering the DTY price center by 100-200 yuan/ton in the short term. For downstream buyers, this means a temporary cost advantage, but they must also be wary of the 'buy on rising, not falling' mentality, which could further delay procurement and exacerbate upstream destocking difficulties.
The sentiment transmission effect within the polyester filament sector cannot be ignored. Historically, price adjustments by leading companies often trigger industry-wide follow-ups within 3-5 working days. Although the current adjustment is modest in magnitude, its signal is strong: it shows that even during the traditional off-season, top players choose to proactively cut prices to clear inventory rather than hold prices and wait. This will accelerate the convergence of overall polyester filament prices toward cost levels.
While the bearish score for polyester staple fiber is slightly lower than for filament, the futures market has already reacted. The decline in the 2609 contract and the increase in short positions reflect the financial market's bearish outlook. Staple fiber and filament share the same raw materials—PTA and MEG—so cost linkages are strong. If filament continues to weaken, staple fiber will find it difficult to remain immune.
Practical Recommendations: Seizing Windows and Managing Risks
For Buyers - Current polyester DTY prices are in a downward channel, but the full extent of the decline has not yet been realized. It is recommended that buyers adopt a 'staggered price-locking' strategy, avoiding large one-time orders at high prices, while using futures tools to hedge against short-term volatility.\n- Monitor follow-up price adjustments from Rongsheng and other leading companies. If a second round of cuts occurs within a week, it indicates destocking pressure exceeds expectations, and buyers may consider increasing procurement volumes.
For Foreign Trade Companies - Export order quotations need to be adjusted accordingly. For forward contracts already signed, it is advisable to negotiate price renegotiation clauses with suppliers to avoid profit inversion due to falling raw material costs.\n- Pay attention to price linkages in Southeast Asian markets. Given China's significant share of global polyester filament exports, domestic price cuts may trigger follow-on declines in markets such as Vietnam and India, affecting the pricing competitiveness of export orders.
Overall, this price adjustment is a clear signal that the weak supply-demand balance in the polyester chain has been broken. Prices still have room to decline in the short term, but in the medium term, attention should be paid to the start of autumn/winter orders and changes in crude oil cost support. Industry participants should abandon a wait-and-see attitude and proactively adjust inventory and pricing strategies.
