Caution is rippling upward through the chemical fiber market. On June 22, the average sales-to-production ratio for sampled polyester filament yarn enterprises stood at only 39.5%, a marginal increase of 1.3 percentage points from the previous trading day. What does this figure imply? For every 100 tons of polyester filament yarn produced that day, fewer than 40 tons were absorbed by the market. For any chemical fiber plant reliant on economies of scale, this is a glaring warning signal.
Behind the Numbers: Supply-Demand Imbalance
When the sales-to-production ratio consistently falls below 50%, inventory accumulation accelerates significantly. Public data reveals a highly polarized distribution among sampled enterprises—some achieved 120%, but the majority clustered between 20% and 40%, with a few even recording 0%. This divergence indicates that demand is not entirely absent; rather, it is concentrating among a handful of suppliers with price or quality advantages, while most firms face shrinking orders.
Polyester filament yarn is a core intermediate in the chemical fiber chain, and its sales performance directly impacts upstream PTA and MEG markets as well as downstream weaving and dyeing sectors. The current low ratio is essentially a transmission effect of subdued consumer demand in end-use sectors like apparel and home textiles. Weaving mills, facing insufficient orders themselves, are reluctant to stockpile and instead adopt a just-in-time purchasing strategy.
The Cost-Price Dilemma
While demand weakens, upstream raw material costs have not fallen sharply in tandem. Prices of PTA and MEG remain influenced by international crude oil fluctuations and their own supply-demand dynamics, keeping production costs for polyester filament yarn relatively rigid. Mills face a dilemma: cutting prices to stimulate sales could further compress already thin processing margins, while holding prices risks inventory buildup and capital tie-up.
Historical patterns suggest that when the sales-to-production ratio stays below 40% for consecutive days, the industry typically responds with voluntary production cuts or maintenance shutdowns to rebalance supply. Multiple issues of the "Chemical Fiber Evening News" from June 18 to 26 have reported similarly low ratios, indicating this is not an isolated event but a developing trend. The market must be wary: if downstream demand fails to recover during the traditional peak third quarter, production cuts may shift from individual corporate actions to a collective industry move, destabilizing the entire chemical fiber supply chain.
Ripple Effects in Industrial Clusters
Major polyester filament yarn production bases are located in textile clusters such as Xiaoshan and Shaoxing in Zhejiang, Shengze in Jiangsu, and Changle in Fujian. Small and medium-sized chemical fiber enterprises in these regions are highly sensitive to order fluctuations. A persistently low sales-to-production ratio likely leads to reduced operating rates, which in turn affects local employment, logistics, and procurement of auxiliary materials (e.g., packaging, chemicals). For buyers relying on these clusters, it is prudent to assess the risk of potential supply delays or specification shortages from some suppliers.
Foreign trade firms face even greater complexity. Overseas inventory digestion cycles are typically longer than domestic ones. A sustained low ratio domestically may signal greater downward pressure on export quotations. However, fluctuations in the RMB exchange rate and restocking demand in some overseas markets could create windows for competitive export orders. The key lies in finding a balance between price and delivery reliability.
Practical Recommendations
For Procurement Teams - Re-evaluate current suppliers' inventory levels and supply stability to avoid disruptions caused by individual plant output cuts. - Leverage the current market caution to negotiate more flexible payment terms or small-lot, frequent purchasing contract clauses with suppliers. - Monitor upstream raw material (PTA, MEG) price trends; if costs decline, consider locking in prices opportunistically.
For Foreign Trade Companies - Closely track operating rate changes at domestic chemical fiber plants and communicate potential delivery schedule adjustments to overseas customers in advance. - Incorporate floating price clauses in quotations to partially transfer raw material price volatility risk to downstream buyers. - Monitor demand dynamics in emerging textile production regions like Southeast Asia; if domestic prices become competitive, explore new market opportunities.
The current adjustment in the chemical fiber market is essentially a rebalancing of supply and demand. Rather than waiting for a market turnaround, industry participants would be wise to proactively adjust procurement and sales strategies to find certainty within the low sales-to-production cycle.
