Polyester DTY Price Divergence Deepens: Industry Competition Shifts from Cost to Efficiency

On July 3, 2026, a warning signal emerged in China's polyester DTY market: for the same 150D/48F AA-grade semi-dull low-elastic yarn, Rongsheng Petrochemical quoted 9,150 RMB/ton while Zhejiang Juxing Chemical Fiber offered only 9,000 RMB/ton, a gap of 150 RMB/ton. With raw material PTA and MEG prices relatively stable, what does this divergence mean?

The Logic Behind Price Divergence

Superficially, this is a price difference between two companies. But looking deeper into the supply chain, it reflects a fundamental shift in the chemical fiber industry's competitive logic. Over the past two years, with massive integrated PX-PTA-polyester filament capacity being released, the industry has moved from shortage to oversupply. According to public data from the China Chemical Fiber Association, total polyester filament capacity exceeded 62 million tons in 2025, while downstream demand growth slowed to around 3%.

In an oversupplied market, pricing power is no longer solely determined by raw material costs. Rongsheng Petrochemical, with its fully integrated refining-to-spinning chain, can afford a 9,150 RMB/ton price, reflecting both cost advantages from self-supplied raw materials and a need to maintain premium client relationships. Juxing Chemical Fiber, a regional player, adopts a 9,000 RMB/ton strategy focused on rapid inventory turnover and cash flow.

Regional Industrial Cluster Effects

The price divergence is concentrated in Zhejiang's Shaoxing and Hangzhou. Shaoxing, one of China's largest chemical fiber fabric production bases, has a high density of weaving mills with strong price sensitivity. Juxing's low-price strategy directly serves local weaving clusters with short delivery times and low freight, creating a 'direct-from-mill' competitive moat.

Rongsheng, based in Hangzhou, serves a broader client base including medium-to-large weaving mills and traders across Jiangsu, Zhejiang, Fujian, and Guangdong. Its price includes brand premium, quality consistency guarantees, and longer payment terms. This differentiated pricing essentially screens clients by credit rating and order size.

Procurement Implications for Downstream Mills

The current 150 RMB/ton gap translates into tens of thousands of RMB in monthly cost savings for a medium-sized weaving mill consuming dozens of tons of raw materials daily. But low price isn't always optimal. Buyers must evaluate: Is the quality consistency of low-price yarn stable? Is supply timely? What are the return-and-replace costs in case of quality issues?

Historical data from Q4 2023 shows a similar price gap, where some mills suffered batch color differences and strength failures from chasing low prices, leading to fabric return losses far exceeding raw material savings. Thus, the current divergence offers a 'stress test' opportunity for buyers to reassess suppliers' comprehensive service capabilities within the price range.

Concerns and Opportunities in Foreign Trade

For export-oriented weaving mills using polyester DTY, price divergence means more flexibility in export quotes. However, overseas buyers—especially in Europe and America—increasingly demand traceable supply chains. Low-price raw materials without verifiable provenance may face 'green barriers' at export.

Meanwhile, rapid textile capacity expansion in Southeast Asia is squeezing China's conventional polyester product export space. In 2025, China's direct polyester filament exports grew about 12% year-on-year, but average export prices fell 4%. This means domestic firms can no longer sustain on price competition alone; they must pivot to differentiated products like recycled polyester or functional DTY to maintain margins.

Practical Recommendations

For Procurement Managers - Build a 'price-service' dual evaluation framework: break down the 150 RMB/ton gap into logistics cost, payment term cost, and return risk cost to calculate total procurement cost, not just list price. - Use the current price window to sign 'tiered price agreements' with two or more suppliers: automatically adjust procurement ratios when prices move beyond a set threshold to lock in some low-cost supply. - For regional suppliers like Juxing, increase on-site factory audit frequency, focusing on capacity utilization and inventory turnover days, to avoid supply disruption from chasing low prices.

For Foreign Trade Companies - Convert raw material price gaps into export quote flexibility: build in a 150-200 RMB/ton raw material cost buffer when quoting to improve competitiveness. - Prioritize suppliers with GRS or OEKO-TEX certifications, even at slightly higher prices, to command premiums in European and American markets. - Monitor Southeast Asian demand for conventional polyester DTY: Vietnam and Indonesia's weaving capacity expansion continues in 2026, boosting import demand for mid-to-low-end DTY. Consider a 'raw material + fabric' bundled export model.
