At 6,020 yuan per ton, Hengli Petrochemical's July PTA contract settlement price stands 130 yuan above the Zhengzhou Commodity Exchange's PTA main contract (2609) closing price of 5,890 yuan on July 22. This spot premium signals that the market's expectation of tight PTA supply-demand balance remains intact, reinforcing the cost transmission logic across the polyester chain.
Background
Hengli Petrochemical, one of China's largest PTA producers, sets a monthly contract settlement price widely regarded as an industry benchmark. The July settlement of 6,020 yuan/ton is not an isolated adjustment but an official confirmation of the persistent strength in the PTA spot market since Q2. The backwardation structure—spot above futures—further underscores the spot market's dominance.
The timing of this announcement, late July, coincides with the critical Q3 restocking window for downstream polyester mills. As PTA is the core raw material for polyester staple fiber, POY, DTY, and FDY, this price directly shifts the cost baseline for the entire chain. Industry practice dictates that contract settlement prices serve as pricing benchmarks for long-term customers, meaning the 6,020 yuan level will influence procurement costs for at least the next month.
Industry Impact
The cost shock from the PTA settlement increase cascades downstream. For polyester staple fiber, where PTA accounts for over 70% of raw material costs, a 130 yuan/ton rise in PTA translates to roughly 90 yuan/ton higher production costs. The Zhengzhou exchange's polyester staple fiber main contract (2609) closed at 7,478 yuan/ton on July 22, with upward momentum likely from cost support.
The logic is similar for filament yarns. POY, DTY, and FDY consume approximately 0.85-0.9 tons of PTA per ton of product. The cost increment from the PTA hike is about 110-117 yuan/ton—a significant burden for an industry with already thin margins. Given that downstream weaving mills maintain high operating rates, cost pass-through to end users is probable.
In key polyester filament production hubs like Xiaoshan and Shaoxing in Zhejiang, mills have begun adjusting pricing. Some factories raised POY and FDY ex-factory prices by 50-100 yuan/ton immediately after the settlement announcement, attempting partial cost pass-through. Whether end-users accept these increases depends on their order profitability and payment cycles.
