On July 10, 2026, the average sales-to-production ratio of polyester filament yarn sample enterprises stood at only 35.5%, a sharp decline of 4.9 percentage points from the previous trading day. This means that for every 100 tons of polyester filament yarn produced that day, fewer than 36 tons were purchased by downstream buyers, leaving over 60% of output as inventory, directly pressuring factory cash flow.
Market Signals Behind the Data
Looking at the distribution of individual sales-to-production ratios, the lowest was 0% and the highest was only 70%, with the median falling in the 25%-30% range, indicating widespread weak sales across most enterprises. The 0% figure is particularly alarming—it suggests that at least one factory received virtually no new orders that day.
This steep decline is not due to a sudden evaporation of demand but rather the inevitable result of a recent concentrated replenishment by downstream users. The textile industry’s inventory cycle typically follows a pattern: 'impulse buying → inventory digestion → wait-and-see → reordering.' The concentrated replenishment in early July has exhausted demand for the next one to two weeks, pushing the market into a typical 'post-replenishment vacuum.'
Ripple Effects Across the Supply Chain
Polyester filament yarn is a key intermediate product in the chemical fiber supply chain. Its sales-to-production ratio directly influences upstream demand for PTA and MEG, as well as downstream weaving and dyeing capacity utilization. If the current ratio of 35.5% persists, three transmission effects are likely:
- Upstream raw materials: Procurement of PTA and MEG will slow, weakening price support. Polyester filament yarn mills may proactively reduce operating rates to destock, lowering raw material consumption and further depressing PTA prices.
- Midstream production: Inventory pressure at polyester filament yarn mills will rise, with some factories resorting to price cuts or extended payment terms to stimulate sales, further compressing profit margins.
- Downstream weaving: Weaving mills are currently focusing on consuming raw materials purchased earlier, with little appetite for new orders. This in turn constrains polyester filament yarn shipments, creating a negative feedback loop.
Regional Industrial Cluster Reactions and Expectations
In key polyester filament yarn production and sales regions such as Shengze, Changxing, and Xiaoshan, enterprises will face the challenge of high short-term inventory. Historical experience shows that when the sales-to-production ratio falls below 40% for three consecutive days, factories are highly likely to initiate production cuts or maintenance plans. The current data has not yet formed a trend, but if the ratio fails to improve over the next two days, expectations of production cuts will shift from speculation to action.
For buyers, this is a classic 'buyer's market,' but they should be cautious of quality risks amid price declines—some factories may lower product standards to quickly destock. Foreign trade companies need to monitor the pace of overseas orders to avoid frequent adjustments in export quotations due to domestic price volatility, which could undermine customer trust.
Practical Recommendations
For Buyers - Leverage the current buyer's market by placing smaller, phased orders rather than making large one-time purchases. Wait for the sales-to-production ratio to stabilize before committing to long-term orders. - Prioritize suppliers with relatively stable ratios (e.g., above 40%), as these enterprises face less financial pressure and are more likely to maintain product quality. - Monitor PTA and MEG price trends. If upstream raw materials continue to weaken, polyester filament yarn still has room to fall, so there is no need to rush into bottom-fishing.
For Foreign Trade Companies - Adopt a 'short-cycle pricing' approach for export quotations, with price adjustment windows of 7-10 days, to avoid losses on overseas contracts due to rapid domestic price fluctuations. - When communicating with overseas downstream clients, proactively explain the cyclical nature of domestic inventory adjustments to reassure them about supply stability. - Keep an eye on RMB exchange rate fluctuations. The price spread between domestic and international chemical fiber products may widen due to exchange rate changes, requiring dynamic adjustments to export strategies.
The sharp drop in the polyester filament yarn sales-to-production ratio is a normal part of market self-correction, but the 35.5% figure has already approached the industry's warning line. The trend over the next week will determine whether this adjustment is a short-term fluctuation or a turning point in the cycle.
