On July 17, the average sales-to-production ratio of polyester filament yarn sample enterprises stood at only 33.0%, down 0.1 percentage points from the previous trading day. This figure means that for every 100 tons of polyester filament yarn produced, only 33 tons were absorbed by the market, leaving 67 tons to be added to inventory. Demand is weak, buying sentiment is low, market transactions are sluggish, and production-to-sales performance is mediocre. This is not an isolated incident but a concentrated reflection of the recent softness in end demand across the chemical fiber industry.
Market Signals Behind the Sales Data
Looking at the detailed sales data released for the day, the distribution of sales-to-production ratios among sample enterprises was highly dispersed: the lowest value was 0%, the highest was 60%, and most enterprises clustered in the 20%-35% range. This "low on both ends, scattered in the middle" structure indicates that the market lacks a unified driving force. Downstream weaving enterprises are only making small purchases for rigid replenishment and have no intention of building inventory proactively.
A sales-to-production ratio consistently below 40% is a clear "warning line" signal in industry practice. Typically, when the ratio is between 40% and 60%, the market is in a weak balance; above 80% implies supply shortage. The current 33% ratio directly points to a phase of oversupply in the polyester filament yarn sector, with inventories passively accumulating.
For producers, rising inventories mean increased capital occupation. Some enterprises may be forced to adopt measures such as price cuts or production maintenance to relieve pressure. For traders, speculative stocking willingness has dropped to freezing point, further shrinking market liquidity.
Supply Chain Transmission Logic
Polyester filament yarn is a core product in the midstream of the textile industry chain. Its upstream raw materials are PTA (purified terephthalic acid) and MEG (monoethylene glycol), while downstream it directly connects to grey fabrics, finished fabrics, and ultimately to end-consumer sectors such as apparel and home textiles. The low sales-to-production ratio is essentially a lagging manifestation of weak end demand transmitting upstream.
Recently, domestic apparel retail growth has slowed, and foreign trade orders have been lackluster due to destocking cycles overseas. This has led to lower operating rates among weaving enterprises, which naturally reduces their procurement of polyester filament yarn, forming a negative feedback loop: weak end demand → low weaving operating rates → reduced polyester yarn procurement → low sales-to-production ratio.
On the cost side, PTA and MEG prices have recently shown a volatile and weak trend, failing to provide cost support for polyester filament yarn. When "weak demand" and "falling costs" occur simultaneously, the downward pressure on the polyester filament yarn market becomes more pronounced.
On-the-Ground Sentiment in Industrial Clusters
In major consumption areas for polyester filament yarn, such as Keqiao in Shaoxing and Shengze in Wujiang, traders have recently reported fewer inquiries and longer transaction cycles. Some weaving enterprises have begun to proactively reduce operating rates from the previous 70%-80% to around 60% to control finished product inventory. This "production based on sales" strategy further compresses the procurement volume of polyester filament yarn.
Notably, sales performance varies significantly among different types of polyester filament yarn: conventional varieties (e.g., POY 75D/36F) face the greatest inventory pressure, while differentiated varieties (such as cationic, flame-retardant, and antibacterial functional yarns) show relatively better sales due to stable demand in specific downstream applications. This divergence suggests that homogeneous products suffer more during demand downturns, and product structure upgrading is key to withstanding cyclical fluctuations.
Short-Term Outlook and Operational Strategies
From historical patterns, July and August are typically the off-season for the textile industry. Coupled with the weaker-than-expected recovery of end orders this year, it is difficult to see a significant rebound in polyester filament yarn sales-to-production ratios in the short term. It is expected that over the next 2 to 4 weeks, the ratio will continue to hover at a low level of 30%-40%, and enterprise inventories may continue to rise.
On the upstream raw material side, the trend of PTA and MEG will determine the cost floor for polyester filament yarn. If raw material prices fall further, polyester filament yarn may follow suit, but the extent of the decline depends on whether the supply-demand contradiction intensifies. If raw material prices stabilize, polyester filament yarn prices are likely to consolidate weakly.
For market participants, the following indicators should be closely monitored:
- Changes in downstream weaving enterprise operating rates
- Inventory days of polyester filament yarn factories
- PTA/MEG price trends and plant maintenance dynamics
- Export data for end-use apparel and home textiles
Practical Recommendations
For Buyers - The current low sales-to-production ratio means greater bargaining power. Consider phased procurement to lower costs, but avoid large one-time stockpiling to guard against further price declines. - Focus on suppliers with high inventory and financial pressure, as they may offer more flexible payment terms or price concessions. - Increase the proportion of differentiated varieties in procurement to meet downstream customer demand for functional fabrics.
For Foreign Trade Enterprises - Closely monitor the inventory destocking progress in major overseas markets (e.g., EU, USA). If overseas retailers start replenishing, it may stimulate domestic weaving orders. - Take advantage of current low raw material prices to lock in costs for forward orders, enhancing price competitiveness. - Strengthen communication with downstream fabric customers to understand changes in their end orders and adjust procurement schedules accordingly.
