29.5%—that was the average sales-to-production ratio for polyester filament yarn sample enterprises on June 25. Dropping 16.1 percentage points from the previous trading day’s closing data, the market has essentially ground to a halt. For any industry insider watching the chemical fiber market, this number signals far more than a surface statistic: the continuous decline in costs has completely crushed trading sentiment, and downstream weaving mills are voting with their feet.
Sales Freeze: The Real Market Behind the Numbers
Looking at the specific sample data, the day’s sales ratios were highly dispersed, with most enterprises concentrated in the 10% to 40% range, and several zero-transaction records appearing. A typical data set includes: 70%, 40%, 30%, 20%, 0%, 20%, 10%, 20%, 10%, 0%, 40%, 30%, 60%, 20%, 20%, 18%, 30%, 20%, 40%. Notably, two instances of zero transactions were recorded, and only a handful of enterprises achieved ratios of 60% or 70%. This means the vast majority of polyester filament yarn producers barely sold any product that day.
This sales decline is not an isolated event. Comparing similar evening reports from the previous week (June 16, 12, 10, and May 29), the market had been hovering at low levels, but the June 25 data pushed this weakness to an extreme. For polyester plants, a sales ratio consistently below 40% implies dangerous inventory accumulation, with cash flow pressure quickly transmitting to the production side.
Cost Side Breakdown: Why Falling Upstream Prices Didn’t Stimulate Purchases
Conventional logic suggests that falling raw material prices should trigger downstream bargain-hunting restocking. But the sales data from this round shows that mechanism has failed. The industry commentary—'the larger cost decline has suppressed trading sentiment'—hides a deeper market psychology: when a downtrend is established with no visible bottom, buyers choose indefinite waiting.
The upstream raw materials for polyester filament yarn are primarily PTA and MEG, both of which have shown a unilateral downward trend recently. Falling raw material prices should reduce polyester yarn production costs, theoretically giving factories room to offer discounts and boost sales. But the fact that sales ratios fell instead of rose indicates that downstream weaving mills believe current prices have not yet bottomed out, and simultaneously, their own orders are insufficient, leaving no urgent need to stockpile. This is a textbook negative feedback loop of 'the more it falls, the less they buy.'
Downstream Transmission: Weaving Mill Order Shortage Is the Root Cause
The root of low sales ratios lies in end-user demand. Weaving mills are the direct consumers of polyester filament yarn, and their purchasing decisions depend entirely on their own order books. Currently, the overall textile and apparel end-consumer market is weak: foreign trade orders have been slow to recover due to overseas destocking cycles, while the domestic market faces challenges from weak consumer confidence. Weaving mill operating rates are generally low, slowing their consumption of raw materials, and naturally they have no incentive to stockpile heavily during a price downtrend.
Looking at the industry chain transmission, pressure from the cost side has failed to be effectively passed downstream, instead forming an inventory bottleneck at the polyester stage. To maintain cash flow, polyester filament yarn factories are forced to passively cut prices, which further reinforces downstream wait-and-see attitudes. The entire chain is trapped in a vicious cycle of 'price cuts → wait-and-see → more price cuts.'
Industry Response: Production Cuts and Inventory Reduction as the Only Options
Faced with an extreme sales ratio below 30%, polyester factories have very limited room to maneuver. Proactively cutting production and reducing operating rates is the most direct way to relieve inventory pressure. In fact, some major factories have already begun maintenance shutdowns or output reductions, though the effects have yet to show in the sales data.
For buyers, the current market landscape presents both risk and opportunity. The risk is that prices may continue to fall, making early purchases a losing bet. The opportunity is that once prices hit the cost line—or even break below cash costs—factories will be forced into large-scale production cuts, at which point supply-demand dynamics will reverse and a price bottom will emerge. The key is judging when that bottom arrives.
