The September 4 production-sales data sent a wake-up call to the polyester filament market: the average sales-to-output ratio of sample enterprises was only 21%, down sharply by 4.8 percentage points from the previous trading day. Behind this figure is a collective 'vote with feet' by downstream users against high-priced raw materials—buying remained strictly just-in-time, and trading was so sluggish that you could hear a pin drop.
The Price Stalemate Behind the Data
A sales-to-output ratio below 30% is rare within the year. Disaggregating the day's sample data reveals an extremely polarized distribution: some enterprises reported relatively active transactions at 40%, while many recorded zero transactions, with the middle tier generally concentrated in the 10%-20% range. This dumbbell-shaped distribution indicates a lack of consensus expectations in the market, with buyers and sellers holding firm on price and transactions occurring only sporadically.
High-price resistance is not unfounded. Upstream raw material costs remain elevated, strengthening filament factories' resolve to keep prices firm. However, downstream weaving and dyeing enterprises see their order profits squeezed, and their acceptable tolerance for raw material increases is nearing a tipping point. When cost-push inflation meets weak demand, the profit distribution contradiction along the supply chain concentrates precisely in the sales-to-output ratio.
Transmission and Regional Responses
This stalemate is transmitting down the supply chain. Weaving enterprises, to control costs, are forced to reduce raw material inventory days, shifting procurement from 'stockpiling in anticipation of price rises' to 'buying as needed.' Meanwhile, terminal apparel and home textile brands are more cautious in placing orders, lengthening the entire supply chain's stocking cycle and transmitting capital pressure from raw materials to finished goods.
From a regional industrial belt perspective, traders in major polyester filament production and sales areas such as Shengze and Changxing report that although inquiries exist, the deal closure rate is low, and market sentiment is dominated by wait-and-see. Some small and medium-sized weaving factories have chosen to proactively reduce operating rates, alleviating raw material inventory pressure by lowering utilization, which in turn further weakens immediate demand for polyester filament.
Short-Term Outlook and Operational Strategies
Considering both supply and demand, polyester filament prices are likely to maintain a high-level volatile pattern in the short term—upstream cost support remains, and factories will not easily concede on price. However, if downstream resistance persists and the sales-to-output ratio remains depressed for an extended period, factories may be forced to schedule maintenance or cut production, potentially leading to price softening. For market participants, this adjustment is both a risk and an opportunity for repricing.
For Procurement Departments - Stick to just-in-time purchasing, avoid large-scale stockpiling at high prices, and keep inventory cycles within 7-10 days. - Place orders in batches and monitor factory sales-to-output ratios; if they remain below 30% for several consecutive days, test the waters for price negotiations. - Sign short-term floating price contracts with upstream suppliers to lock in part of raw material costs and hedge against unilateral price fluctuations.
For Foreign Trade Enterprises - Closely track RMB exchange rate fluctuations and reserve a 2%-3% buffer in quotations. - For overseas orders, adopt formula-based pricing (raw material price + processing fee) and include price adjustment clauses. - Monitor polyester filament prices in competitive markets such as Southeast Asia and South Asia, adjust export pricing strategies promptly, and protect market share.
Markets always find direction amidst divergence. The current low sales-to-output ratio may well be the prelude to a rebalancing of profit distribution across the supply chain. Those who can read the signals first will be better positioned to take the lead when the next market cycle begins.
