Polyester POY prices showed notable divergence on July 6, 2026, with quotes from seven major Zhejiang producers ranging from 7,800 to 8,400 yuan per ton, a spread of 600 yuan per ton. This magnitude is unusual in recent years, signaling a re-pricing process across the polyester supply chain.
Cost Logic Behind Price Divergence
Rongsheng Petrochemical offered the lowest price at 7,800 yuan/ton, while Tongkun Group quoted 8,400 yuan/ton. Both are based in Hangzhou but adopt opposite strategies. Industry data indicates that large integrated refining-chemical companies have stronger cost control across the PX-PTA-polyester chain. Rongsheng’s low-price strategy may aim to accelerate destocking or capture market share.
In contrast, Tongkun’s high quote reflects confidence in product quality and brand premium. As one of China’s largest polyester filament producers, Tongkun’s products are competitive in differentiated varieties such as fine denier and high-tenacity yarns, with high customer stickiness, allowing it to maintain higher prices.
Regional Industrial Belt Transmission
Juxing Chemical in Shaoxing quoted 8,050 yuan/ton, Jiabao New Fiber at 8,250 yuan/ton, while Kaishi Group in Hangzhou offered 8,300 yuan/ton. The 200-500 yuan/ton spread between Shaoxing and Hangzhou reflects not just transportation costs but different downstream industrial structures.
Shaoxing, as a major textile fabric hub, has a high concentration of weaving mills with large demand and frequent purchases, prompting local chemical fiber enterprises to offer slightly lower prices to maintain client relationships. Hangzhou serves more high-end fabric markets and export orders, where downstream firms are less price-sensitive and prioritize product stability and delivery reliability.
Impact on Downstream Procurement Strategy
A 600 yuan/ton spread means a cost difference of over 6% per ton of POY. For a medium-sized weaving mill consuming 100 tons per month, the monthly raw material cost difference could reach 60,000 yuan, enough to alter profit margins.
Historically, when POY price divergence intensifies, it often signals an inventory adjustment cycle. Low-price vendors may face inventory pressure, while high-price ones likely have product differentiation. Downstream firms should not simply choose the lowest price but evaluate delivery stability, product consistency, and after-sales service.
Industry Concentration and Pricing Power Shift
The seven quoted companies are all top chemical fiber players in Zhejiang, but their divergent strategies reveal deepening internal fragmentation. Rongsheng and Tongkun represent two paths: scale-cost leadership versus quality differentiation.
China’s polyester filament industry CR5 exceeds 60%, yet price wars persist. Competition among leading firms is shifting from pure price competition to comprehensive competition in supply chain efficiency and product added value. This trend will force small and medium chemical fiber companies to accelerate niche market targeting or face consolidation.
