Polyester Filament Yarn Prices Diverge: Signals from Zhejiang's Fiber Industrial Belt

The price gap for the same specification of polyester FDY has widened to 350 CNY per ton among different chemical fiber companies in Zhejiang. Public quotes on August 7 showed that for the 150D/96F semi-dull variety, Tongkun Group quoted 8,760 CNY/ton, while Zhejiang Jiabao Fiber only quoted 8,410 CNY/ton. This spread is uncommon in the past two years; it is not merely a difference in pricing strategy but a direct reflection of cost structure and customer positioning within the industrial belt.

Industrial Belt Divergence Behind the Price Gradient

The numbers on the quote sheet are simple, but they imply differences in the companies' positions in the industrial chain. Tongkun and Rongsheng, as polyester leaders, have integrated PTA-to-spinning facilities and high raw material self-sufficiency, theoretically implying lower costs, yet they quote higher. This is not cost-driven but reflects brand premium and product stability. Leading enterprises supply high-end weaving customers with stricter control over color fastness and evenness, and the quality premium naturally shows in their quotes.

In contrast, Shaoxing-based companies like Jiabao Fiber and Juxing Chemical quoted in the range of 8,410-8,500 CNY/ton, closer to the market average. These companies mostly purchase PTA or MEG externally, so raw material cost fluctuations pass through directly to selling prices. Their customers are mainly small and medium weaving mills with high price sensitivity, hence more flexible pricing strategies. Notably, Hangzhou Kaishi Chemical quoted 8,650 CNY/ton, falling in between, indicating that even within the same region, product mix differences lead to significant price gaps.

Transmission to Downstream Procurement and Market Expectations

Price divergence directly impacts procurement decisions of downstream weaving enterprises. A gap of 350 CNY/ton means a difference of about 300-400 CNY per ton of fabric cost, which, given the thin profit margins of greige fabrics, is enough to shift order allocations. If buyers only chase low prices, they may overlook quality fluctuations leading to higher defect rates; if they blindly follow high prices, they compress their own margins. Thus, this gap forces buyers to establish a more refined supplier evaluation system rather than simple price comparison.

From a market expectation perspective, high quotes from leaders and low-price volume from smaller players are unlikely to change in the short term. If polyester raw material prices remain volatile, the ability of small and medium enterprises to pass on costs will weaken further, potentially accelerating industry consolidation. For traders, the widening gap means arbitrage opportunities, but they must be wary of quality stability of low-priced sources to avoid small gains and large losses.

Practical Recommendations

For Buyers - Establish a multi-supplier comparison mechanism, but incorporate quality indicators (e.g., CV% of evenness, boiling water shrinkage) into contract terms to avoid price-only decisions. - Monitor the price gap between leaders and smaller producers; if it exceeds 400 CNY/ton, consider phased procurement to balance cost and risk. - For low-priced sources in Shaoxing, start with small trial orders to verify dyeing uniformity before scaling up.

For Foreign Trade Companies - In export quotes, refer to the price anchor of leading companies to avoid anti-dumping risks from low-price competition. - Leverage the price divergence by building flexible partnerships with suppliers of different tiers, switching sources based on overseas order grades. - Pay attention to operating rate changes in the Zhejiang industrial belt; widening gaps often accompany capacity adjustments, and early long-term contracts can hedge against supply fluctuations.
