On August 28, the average sales-to-production ratio of polyester filament sample enterprises stood at 34.7%, up only 5.3 percentage points from the previous trading day. This means that for every 100 tons of polyester filament produced that day, less than 35 tons were absorbed by the market. More notably, downstream resistance to high raw material prices has not eased despite the modest improvement, leaving inquiries sluggish and transactions stalled.
Signals Behind the Data
The sales-to-production ratio is a core leading indicator of the health of the chemical fiber supply chain. Behind the 34.7% average lies a wide disparity among sample enterprises: daily ratios ranged from 0% to 500%, with many firms recording 10%-20% and only a few showing exceptional volume. Such extreme divergence does not signal a broad demand recovery but rather suggests localized pulses from individual price cuts or concentrated restocking by major customers.
Historically, late August marks a sensitive transition between off-season and peak season. In previous years, downstream weaving mills typically stock up for the 'golden September and silver October', driving the ratio above 80%. The current 34.7% is significantly lower than historical norms, indicating that pre-season stocking momentum has yet to materialize. This reflects both weak terminal apparel orders and traders' wait-and-see attitudes toward future price trends.
Upstream-Downstream Bargaining and Price Stalemate
The 'high-price resistance' in the polyester filament market essentially stems from a tug-of-war over cost and profit redistribution. Upstream PTA and MEG prices remain elevated due to international oil volatility, squeezing producers' room to cut prices. Meanwhile, downstream weaving mills face difficulties in raising their own product prices and rising inventory, leaving their tolerance for higher raw material costs near a tipping point.
The result is a stalemate where prices can neither rise nor fall easily. For filament producers, proactive price cuts might stimulate some essential demand but would further erode already thin processing margins. Maintaining prices, however, means bearing the pressure of low sales ratios and tied-up capital. Some mid-sized enterprises are already adjusting settlement methods, such as extending credit terms or offering more flexible delivery schedules, to spur volume without directly cutting prices.
Feedback from industrial clusters in Shengze and Changxing, major consumption hubs for polyester filament, shows weaving operating rates hovering around 60% with rising greige fabric inventories. This suggests that terminal demand has not genuinely improved. The current low sales ratio is not a short-term mismatch but rather reflects downstream players actively destocking and shortening raw material procurement cycles.
Implications for Market Participants
The persistently low sales-to-production ratio is forcing a re-evaluation of pricing mechanisms. The old one-way cost-push transmission model is no longer sustainable in a weak demand environment. Going forward, polyester filament prices may be driven more by actual transaction volumes than by factory list prices. For buyers, this means wider bargaining room between quoted and transacted prices, but they should be wary of traders creating artificial 'fake rise' sentiments.
Moreover, the volatile daily ratio underscores that a single day's figure lacks trend significance. Market participants should focus on cumulative ratios over at least a week and correlate with weaving operating rates and greige fabric inventory to form a more robust view of supply-demand dynamics.
