East China PET FDY Price Divergence: 8,500 Yuan/Ton Becomes Short-Term Battleground

On August 6, the PET FDY market in East China presented a telling detail: for the same 150D/96F semi-dull AA-grade FDY, Rongsheng Petrochemical and Zhejiang Juxing both quoted 8,500 yuan/ton, while Zhejiang Jiabao quoted 8,410 yuan/ton. The 90-yuan gap, though small, exposes divergent market strategies. With limited upstream volatility, this divergence mirrors differences in inventory levels and order books across mills.

The Logic Behind Quote Divergence

A 90-yuan price gap for the same specification is uncommon in FDY spot trading. The 8,500 yuan/ton level sits near the midpoint of the past month's quotation range, and leading mills' adherence to this price signals an intention to stabilize the market. In contrast, the 8,410 yuan/ton quote from Jiabao is closer to the cash cost line for small and medium polyester plants, indicating a priority on maintaining operating rates. For buyers, the spread between listed and actual transaction prices often ranges from 50 to 100 yuan, meaning Jiabao's offer may already approach downstream cost expectations.

Geographically, all three mills are based in Zhejiang—Hangzhou and Shaoxing are among the most concentrated FDY production areas. This intra-regional divergence suggests the market is not monolithic but shaped by company scale, contract ratios, and inventory positions. Large mills maintain price rigidity through long-term contracts, while smaller mills rely more on spot sales, creating a price ladder for the same product.

Transmission to Weaving and Trade Sectors

For weaving enterprises in Jiangsu and Zhejiang, a 90-yuan gap may seem minor, but in bulk purchases it affects per-ton costs. A typical 50-ton order would see a cost difference of 4,500 yuan, roughly equivalent to a week's processing profit for a medium-sized loom. Thus, the divergence offers room for price comparison, but buyers must verify the validity of quotes—lower prices may come with minimum order quantities or payment terms.

For foreign trade firms, current FDY prices are relatively stable, but two risks warrant attention: first, if large mills sustain price support, new orders after October may see upward adjustments; second, if small mills' low-price strategy triggers follow-ups, it could accelerate inventory clearance and set the stage for a later rebound. Exporters are advised to lock in forward raw material costs to avoid margin compression from domestic price swings.

Short-Term Outlook and Operational Guidance

Overall, FDY prices are likely to fluctuate narrowly in the near term. Upstream PTA and MEG lack clear directional drivers, and downstream weaving operating rates, though seasonally recovering, face limited terminal order growth. The 8,500 yuan/ton level may act as a psychological battleground, while 8,410 yuan/ton could serve as a short-term floor.

For Buyers - Use actual transaction prices as the benchmark, not listed quotes; inquire with multiple suppliers to gauge negotiation room. - For orders above 50 tons, negotiate with 8,500 yuan/ton as an upper limit, focusing on volume discounts or payment terms. - Monitor large mills' pricing moves; if 8,500 yuan/ton holds for two consecutive weeks, consider extending procurement cycles.

For Foreign Trade Firms - Include raw material price linkage clauses in export contracts, or use forward locking tools to hedge FDY volatility. - Leverage the current price gap to establish short-term supply relationships with small mills, but verify delivery stability and quality consistency. - Track operating rates of leading Zhejiang polyester plants; if inventory clearance accelerates, adjust quoting strategies in advance.
