On July 9, the average sales-to-production ratio of polyester filament yarn in the market plummeted to 40.4%, a sharp drop of 63.2 percentage points from the previous trading day. This shift in public data is not an isolated price fluctuation but signals a rapid acceleration in the game rhythm across the chemical fiber supply chain.
Signals Behind the Sales Data
A closer look at the specific data reveals extreme divergence among sample enterprises. Among the 24 data points, the highest reached 180% while the lowest was only 10%, with most companies clustering in the 25%-50% range. This distribution pattern of 'high at the top, low at the tail' indicates not a market-wide downturn but a clear structural divergence—a few companies maintained high sales thanks to product advantages or customer loyalty, while most fell into a trading stalemate.
More notably, the previous day (July 8) saw a concentrated restocking wave that pushed the ratio above 100%. Such impulsive purchases are typically triggered by short-term orders or price fluctuation expectations but lack sustainability. The July 9 data confirms this: restocking demand evaporated within 24 hours, with most buyers withdrawing to watch, leaving only a few with rigid demand to continue replenishment.
Supply Chain Transmission: Shrinking Cycle from 'Rush to Buy' to 'Wait and See'
As a textile intermediate, the sales rhythm of polyester filament directly reflects the operating willingness and inventory strategies of downstream weaving mills. This sharp decline essentially indicates that downstream weaving, after a rapid restocking round, has re-entered a 'de-stocking and wait-and-see' mode. Feedback from major weaving clusters such as Shengze, Changxing, and Xiaoshan shows that operating rates have not rebounded significantly recently, with terminal fabric orders still dominated by short and small lots, lacking sustained large orders.
This means that inventory pressure on upstream polyester plants is re-accumulating. If the sales ratio stays below 50% for an extended period, companies may be forced to cut prices or offer promotions to stimulate sales, squeezing their profit margins. For raw material ends like PTA and MEG, weakening polyester filament sales will curb their upward price elasticity, forming a negative feedback loop from downstream to upstream.
Procurement Windows and Risk Tips
For buyers, the current market is in a 'post-restocking calm,' offering relatively greater room for price negotiation. The July 9 data shows that most companies are willing to accept low sales ratios in exchange for price stability. However, if inventory continues to accumulate, some plants may proactively cut prices to destock before month-end. It is recommended that buyers closely monitor polyester filament plant inventory days and operating rates, and lock in low-priced supplies when inventory pressure rises and sales ratios fall below 40%.
For foreign trade enterprises, vigilance is needed regarding the impact of sales fluctuations on export order delivery and costs. If polyester filament prices weaken due to sluggish sales, it may lower fabric procurement costs in the short term. However, if upstream plants cut production to support prices, it could tighten supply and push up forward prices. It is advised to shorten procurement cycles to 7-10 days and include price fluctuation clauses in supplier contracts to hedge against rapid changes in sales data.
Industry Outlook: Pulsed Restocking as a New Normal
Looking at longer cycles, the polyester filament market in 2024 has repeatedly experienced pulsed fluctuations of 'single-day sales surge followed by a plunge.' This reflects a strategic shift by downstream companies to compress inventory cycles and adopt a 'produce-to-sell' approach amid a weak demand recovery. The speculative model of 'hoarding to wait for price hikes' is being replaced by a 'fast-in, fast-out' risk-averse mode.
For polyester plants, this requires a shift from 'produce-to-sell' to 'sell-to-produce,' using more flexible production scheduling and product switching to meet fragmented downstream demand. For textile industry professionals, understanding the structural changes in high-frequency indicators like the sales ratio is more crucial for grasping market trends than focusing on single-day price movements.
