A 23.5% sales-to-output ratio in polyester filament is, for practical purposes, a "can't sell" number. On September 7, the average ratio of sampled producers rose just 2.5 percentage points from the previous trading day, while individual readings swung from 0% to 130%. That dispersion tells a clearer story than the average itself: there is no unified price consensus in the market.
Structural Divergence Behind the Numbers
Breaking down the daily readings from more than twenty sampled mills, the vast majority sat below 40%, with a few plants reporting zero sales. Only a handful reached 130%, typically driven by concentrated delivery of prior orders or bargain-hunting on low-priced cargo. This "fire and ice" distribution is the hallmark of a sideways market—downstream demand has not disappeared, but buyers simply reject current quotations.
Feedback from industrial clusters in Jiangsu and Zhejiang shows a marked slowdown in procurement pace. News of falling loom utilization has circulated widely, and some mills have extended raw material purchasing cycles from weekly to biweekly. Production-to-order and procurement-to-order have become standard practice. For polyester plants, this leaves only two paths for inventory destocking: price cuts or output reductions. Both compress processing margins.
Why the Cost Transmission Chain Is Stuck
The pricing logic of polyester filament is nominally "PTA + MEG + processing fee," but the current bottleneck lies not on the cost side but in downstream absorption capacity. If upstream raw material prices hold firm, polyester plants face a squeeze between cost-supported pricing and demand-driven discounting. If raw materials weaken in tandem, the downward shift in price centers will further encourage downstream wait-and-see behavior, creating a negative feedback loop.
It is worth noting that downstream resistance to high prices is not a short-term mood but a rational response to compressed order margins. Fabric export quotations are difficult to raise in sync, leaving weaving mills to extract margin from upstream. Under this bargaining structure, a modest rebound in the sales ratio carries no trend significance. The real turning point depends on whether weaving orders can gain volume.
Practical Implications for Procurement and Export
For procurement teams, the current window is for observation, not bottom-fishing. A low sales ratio means polyester plants are willing to concede margin, but the extent depends on inventory pressure rather than the quotation itself. Testing the market with small,分批 orders, locking in processing fees, and avoiding one-time large-volume price locks are more prudent strategies.
For export-oriented enterprises, a sideways raw material market actually supports quotation stability. But two variables warrant caution. First, if weaving production cuts persist, delivery schedules may be passively extended. Second, if polyester plants concentrate maintenance shutdowns, supply contraction could push prices higher later. Contracts should retain price adjustment clauses, and capacity for key specifications should be secured in advance.
For Procurement Teams - Inquire in weekly batches to avoid locking in high costs with a single large order - Negotiate processing fees rather than absolute prices to retain flexibility on raw material fluctuations - Monitor polyester plant inventory days; inventory turning points often precede price turning points
For Export Enterprises - Build a raw material fluctuation range into quotations and add price adjustment mechanisms to contracts - Confirm weaving capacity in advance to prevent delivery delays caused by production cuts - Maintain moderate stock of key fabric specifications to hedge against supply contraction risk
Overall, polyester filament is likely to remain in sideways consolidation in the near term, and a single-day rebound in the sales ratio is insufficient to change the supply-demand landscape. The real signal lies not in the data itself but in loom utilization rates and order visibility on the downstream weaving side.
