On August 6, 2026, Rongsheng Petrochemical (including Shengyuan), a core domestic polyester filament producer, announced cuts in POY prices by 50-100 CNY/ton. Semi-dull POY 75/36 was quoted at 8650 CNY/ton, 150/48 at 8250, and black yarn 300/96 at 8850. This seemingly routine adjustment is actually a clear signal of loosening supply-demand in the polyester chain, prompting downstream weavers and exporters to reassess cost windows and inventory strategies.
Background
As an industry leader, Rongsheng's price moves often set the tone. This cut is not isolated but reflects loose spot supply-demand for POY. Data shows semi-dull POY 75/36 and 100/96 both at 8650 CNY/ton, while 150/48 dropped to 8250, revealing demand divergence between fine and coarse denier. Black yarn 300/96 at 8850 still commands a premium, indicating differentiated products retain value, but the overall price center has shifted downward.
The proactive destocking move points to rising inventory pressure. Industry data suggests August is a transition period between off-season and peak, yet downstream weaving operating rates recovered slowly, with purchases mainly small-lot and need-based, leading to lower polyester plant sales rates. Rongsheng's cut, though modest, carries strong signaling value, aiming to spur downstream bargain hunting and relieve its own stock pressure.
Industry Impact
In the spot market, Rongsheng's cut will directly lower POY transaction centers. Other polyester plants will likely follow to secure orders, making POY prices prone to decline in the near term. Related futures contracts face weaker expectations and pressure. This means weavers holding raw material inventories face depreciation risks, while those yet to stock up may secure lower costs.
Down the chain, POY price drops will gradually transmit to DTY, FDY, and grey fabrics. Downstream weavers see eased cost pressure, but terminal order prices may weaken in tandem, not necessarily improving margins. For exporters, polyester fabric quotes may drop, boosting price competitiveness, but watch for FX volatility eroding profits. Meanwhile, black yarn and other differentiated products remain relatively firm, signaling sustained demand for functional fabrics and guiding product development.
Deeper, this cut results from the combination of capacity cycle and weak demand. Recent years saw concentrated new capacity releases, while terminal apparel and home textile consumption growth slowed, causing supply-demand mismatch and lower price centers. Rongsheng's proactive cut is both a competitive necessity and a prelude to industry consolidation. Smaller players face greater pressure, and industry concentration is expected to rise.
