The polyester filament market is experiencing a typical 'volume-price divergence' stalemate. On August 28, industry public data showed that the average sales-to-production ratio of sample enterprises was only 34.7%, up 5.3 percentage points from the previous trading day, but still in the low range for the year. Behind this data lies continuous wait-and-see sentiment and resistance from downstream weaving enterprises—high-priced raw materials are not being accepted, yet low-price promotions fail to boost volume, leaving the market in a rare two-way standoff.
Looking at the distribution of sales-to-production ratios among sample enterprises on that day, most companies reported ratios between 10% and 30%, with some even recording zero sales, while a few extreme values reached as high as 500%. This sharp divergence reveals structural differences within the market: a minority of companies maintain higher shipments through differentiated products or long-term orders, while conventional specifications face severe liquidity crises. For purchasers, this means the market is not uniformly weak but offers both structural opportunities and risks.
Event Background
Since late August, polyester filament prices have remained high due to cost-side support, but terminal demand has failed to keep pace. Upstream PTA and MEG prices are influenced by international oil price fluctuations, so the cost support logic still holds; however, downstream weaving and dyeing enterprises are operating at reduced capacity, with new orders mainly consisting of rigid small-lot purchases, and large orders are scarce. This pattern of 'cost-push, demand-drag' has left polyester filament prices with limited upside and downside, prompting market participants to adopt strategies of 'producing based on sales and purchasing as needed.'
Sales-to-production ratio data is the most direct window into market sentiment. A ratio of 34.7% means nearly two-thirds of the day's output failed to convert into actual sales, and inventory pressure is accumulating at the production end. Historical experience shows that when the sales-to-production ratio remains below 40% for consecutive days, producers are often forced to cut prices or conduct maintenance to balance supply and demand. The current 5.3-percentage-point rebound is insufficient to change the trend, and the market is still waiting for clearer directional signals.
Industry Impact
For upstream polyester plants, the low sales-to-production ratio directly tests cash flow management. Filament inventory occupies substantial capital, and if the stalemate persists, some companies may resort to temporary production cuts or early maintenance to alleviate pressure. This implies a potential contraction in filament supply in the short term, which may provide some price support but will also compress raw material procurement demand, transmitting effects back to the PTA and MEG markets.
For downstream weaving enterprises, the current standoff actually offers a brief 'breathing window.' Raw material prices have not fallen significantly, but upward momentum is equally limited, buying time to digest previous high-priced inventories. However, if terminal orders continue to weaken, weaving enterprises' willingness to restock will hardly improve, and the market may enter a negative feedback loop of 'low sales-to-production, high inventory, and price-cut expectations.' Foreign trade enterprises especially need to monitor the pace of overseas demand recovery and avoid taking on excessive inventory risk during a price downcycle.
From a regional industrial cluster perspective, Jiangsu and Zhejiang, as the main production and sales areas for polyester filament, will directly affect the national supply-demand balance through changes in operating rates. Recently, some polyester plants have announced maintenance plans; if maintenance exceeds expectations, it could provide phased support to the market. Overall, however, the industry remains in an active destocking phase, and price rebounds lack sustained momentum.
