On July 17, the average sales-to-production ratio of China's polyester filament yarn sample enterprises dropped to 33%, down 0.1 percentage point from the previous day. This means that for every 100 tons of polyester filament yarn produced, only 33 tons were purchased by downstream enterprises, with the remaining 67 tons turning into inventory. When the sales-to-production ratio consistently falls below the 50% threshold, the supply-demand balance in the chemical fiber supply chain has clearly tilted.
Sales Data Reveals the True Temperature of Demand
From the 24 specific data points provided by sample enterprises, the distribution ranges from 0% to 60%, with over 60% of samples below 30%. The highest value is only 60%, and the lowest is zero. This 'long-tail downturn' distribution pattern indicates that weak demand is not an isolated phenomenon but a widespread industry plight.
Polyester filament yarn, as a bellwether in the chemical fiber market, directly reflects order conditions in downstream weaving, dyeing, and even apparel end-markets. A 33% sales-to-production ratio means the transmission mechanism of end-consumer demand is failing—brand owners and traders show extremely low willingness to replenish inventory, and weaving mills prefer to reduce operating rates rather than increase raw material stocks.
Inventory Accumulation and Price Expectations: The Spiral Downward Pressure
The direct consequence of persistently low sales-to-production ratios is a rapid buildup in polyester plant inventories. According to industry public data, current social inventories of polyester filament yarn are close to historical highs for the same period. Rising inventories mean higher capital occupation costs, forcing plants into a dilemma: either cut prices to clear stocks or reduce production to support prices.
From a price expectation perspective, demand-side sentiment is not optimistic. Buyers show low enthusiasm, adopting a wait-and-see approach, and procurement strategies have further contracted from 'just-in-time' to 'buy only when urgently needed.' This mentality has formed a negative feedback loop across the textile supply chain: fewer end orders → weaving mills cut production → reduced raw material purchases → polyester plants increase inventories → price promotions → downstream waits for even lower prices.
Notably, the cost side (PTA, MEG) has also lacked strong support recently, with crude oil price fluctuations failing to effectively transmit to the polyester segment, further weakening the price floor for polyester filament yarn.
Regional Industrial Belt Reactions: Order Transmission from Keqiao to Shengze
The low sales-to-production ratio of polyester filament yarn has already had a direct impact on the Yangtze River Delta textile industry clusters. In Keqiao District, Shaoxing City, Zhejiang Province—the world's largest textile distribution center—the China Textile City has recently seen a month-on-month decline in transaction volumes, with significantly slower delivery speeds for grey fabrics and finished fabrics.
In Shengze Town, Wujiang District, Suzhou City, Jiangsu Province—a major production base for chemical fiber fabrics in China—the operating rate of weaving mills has fallen from around 75% at the end of Q2 to below 70% currently. Mill owners generally report that foreign trade orders are increasingly characterized by 'small batches, multiple lots,' with large, long-term orders remaining conspicuously absent.
This synchronized cooling from upstream polyester production to downstream weaving indicates that the current situation is not a single-sector inventory adjustment but a complete 'active destocking' cycle across the entire textile supply chain.
Practical Recommendations
For Buyers - Adopt a 'small batch, high frequency' procurement strategy to avoid the risk of price declines from large one-time stockpiles. - Closely monitor polyester plant maintenance schedules and inventory data. A slowdown in inventory growth or the emergence of concentrated maintenance may signal a temporary price bottom. - Negotiate short-term floating price agreements with upstream suppliers to partially transfer raw material price risk through supply chain financial instruments.
For Foreign Trade Companies - Closely track the impact of RMB exchange rate fluctuations on export competitiveness, reserving exchange rate flexibility in order quotes to prevent profit erosion from RMB appreciation. - Leverage current low raw material prices to negotiate price adjustment clauses in long-term framework agreements with overseas clients, locking in cost advantages for the next 6-12 months. - Explore emerging markets in Southeast Asia and the Middle East to diversify reliance on traditional European and American markets, reducing the risk of order volatility from a single market.
Conclusion
The 33% sales-to-production ratio is not an isolated data point but a microcosm of the supply-demand imbalance in the chemical fiber industry. When downstream weaving mills prefer to halt production rather than stock up, when polyester plants' inventories continue to mount, and when signals of end-consumer recovery remain elusive, the entire supply chain must prepare to 'weather the storm.' In the short term, the market will likely maintain a weak and volatile pattern, with a true turning point possibly not emerging until the end of Q3 or Q4, depending on whether a substantial recovery in end-consumer demand materializes.
