Polyester FDY Price Fluctuations: Divergent Quotes in East China Industrial Belt, Downstream Procurement Strategies Need Adjustment

On July 3, 2026, the market quotes for polyester FDY (150D/96F semi-dull AA grade) in East China showed a clear divergence, with the lowest at 8,300 yuan/ton and the highest at 8,650 yuan/ton, a spread of 350 yuan. This fluctuation reflects the ongoing tug-of-war between destocking and cost transmission in the chemical fiber supply chain.

Industrial Logic Behind Price Divergence

Looking at specific quotes, Rongsheng Petrochemical and Zhejiang Juxing Chemical Fiber both reported 8,300 yuan/ton, at the bottom of the range; Zhejiang Tiansheng Chemical Fiber reported 8,510 yuan/ton, Hangzhou Kaishi Chemical Fiber 8,550 yuan/ton, Zhejiang Jiabao New Fiber 8,310 yuan/ton, while Tongkun Group reported 8,650 yuan/ton, the highest among all.

A price spread exceeding 4% for the same specification in the same region is uncommon in normal market conditions. It points to two key variables: first, differences in raw material procurement costs and inventory cycles for PTA and MEG; second, divergent views on market outlook—some mills are pricing low to accelerate destocking, while others defend margins and wait for demand recovery.

Notably, Rongsheng and Juxing, both located in the core industrial belt of Hangzhou and Shaoxing, offered the lowest prices, while Tongkun, also in Zhejiang, quoted the highest. This indicates that price differences are not simply geographic but closely tied to each company's capacity utilization, order structure, and cash flow status.

Transmission Effects on Downstream Buyers

For weaving mills, the current price divergence presents both opportunity and risk. The opportunity lies in the ability to lock in raw materials at 8,300 yuan/ton through price comparison, saving 350 yuan per ton compared to Tongkun's quote—a potential monthly cost reduction of 35,000 yuan for a typical 100-ton monthly purchase.

The risk is that low prices may come with hidden costs in supply stability or quality consistency. Industry public data shows that polyester FDY 150D is mainly used in water-jet weaving and warp knitting, which require high yarn tension uniformity and dyeing consistency. Buyers switching to a new low-cost supplier should conduct small-lot trial weaving and dyeing tests to avoid batch quality issues.

Furthermore, the current quote volatility suggests the market has not yet reached supply-demand balance. If downstream demand remains weak, low-price mills may cut further, dragging the entire industry's price center downward. Conversely, if orders concentrate, low-price supply will quickly tighten, forcing buyers to accept higher quotes.

Practical Recommendations

For Procurement Managers - Establish a multi-supplier comparison mechanism: quotes from Rongsheng, Juxing, and Jiabao (all in the 8,300-8,310 yuan/ton range) can serve as a benchmark against Tongkun's quote to assess price reasonableness. - Prioritize small trial orders: for new low-cost suppliers, first purchase 10-20 tons for trial weaving and dyeing tests before scaling up. - Monitor inventory and futures linkage: PTA futures trends directly affect FDY costs; if PTA falls, delay large purchases; if PTA rebounds, accelerate price locking.

For Foreign Trade Enterprises - Build flexibility into export quotes: with domestic FDY prices fluctuating over 4%, adopt floating pricing formulas (e.g., raw material cost plus processing fee) to avoid margin erosion from raw material hikes. - Leverage regional price differences: for export orders with strict specifications (e.g., 150D/96F semi-dull), prioritize suppliers in Shaoxing and Hangzhou, where quotes are generally lower. - Monitor exchange rates and tax rebate policies: RMB volatility amplifies raw material cost changes; lock forward exchange contracts simultaneously to hedge dual risks.
