On July 8, a set of data worth noting emerged from the chemical fiber market: the average sales-to-production ratio of polyester filament yarn sample enterprises hit 103.6%, a sharp increase of 60.7 percentage points from the previous trading day. A single-day ratio exceeding 100% is rare during the industry's off-season, and a jump of 60 points signals a directional reversal in market sentiment.
For weaving mills and traders who have been in a wait-and-see mode, this signal demands careful interpretation.
Raw Material Side Ignites, Cost Transmission Restarts
The trigger for this sales surge came from upstream. From July 7 to 8, international crude oil prices rebounded consecutively, driving up PTA and MEG futures. This price increase directly altered the cost expectations for polyester filament yarn—under the anticipation of rising cost lines, downstream players activated their 'buy on rising, not on falling' psychology.
Detailed sales data from sample companies show extreme unevenness: the highest ratio reached 300%, while the lowest was only 10%. This disparity indicates that the market is not broadly recovering; rather, leading companies, leveraging pricing strategies and channel advantages, concentrated a wave of orders. Companies with ratios above 200% likely locked in downstream demand through promotional discounts or price guarantee agreements.
This means the 103.6% average is essentially a dual effect of 'rising raw materials plus corporate concessions,' not a true explosion of end demand.
The Window for Inventory Cycle Shift
The second key to understanding this sales pulse lies in the inventory cycle. Entering July, social inventories of polyester filament yarn had been at elevated levels for three consecutive weeks, with some specifications exceeding 25 days of stock. Under inventory pressure, polyester plants had been maintaining price-cutting promotions, but downstream refused to bite.
The sudden rise in crude oil broke this deadlock. For weaving mills, once the raw material price floor is confirmed, the cost of waiting outweighs the risk of early procurement. Thus, the concentrated restocking on July 8 is essentially a collective confirmation of a 'price bottom' by downstream players.
Industry experience suggests that such cost-driven sales pulses typically last 3 to 5 trading days before the market returns to supply-demand fundamentals. However, if crude oil stays high and polyester plants can smoothly raise ex-factory prices, it could initiate a truly meaningful destocking cycle.
Off-Season Gambit in Weaving
July is traditionally the off-season for weaving; the comprehensive operating rate in Jiangsu and Zhejiang has dropped to around 65%. But notably, some foreign trade orders and autumn/winter fabric sampling orders have begun to trickle in. Downstream demand for stocking up for the 'Golden September and Silver October' season is brewing.
The July 8 sales data arrived precisely at this delicate juncture. Downstream companies used the crude oil rally to complete restocking, hedging against future raw material price hikes and preparing ammunition for the peak season. From this perspective, the sales surge is not purely speculative but has a certain industrial rationale.
But risks remain. If end-consumer apparel demand fails to recover in September, the pre-stocked raw material inventory will translate into new financial pressure. Weaving mills must beware of the 'inventory transfer' trap—shifting upstream inventory to their own warehouses does not solve the fundamental problem of weak end demand.
Market Implications and Operational Advice
This surge in polyester filament yarn sales sends three signals to the industry:
- Raw material costs remain the most effective price anchor in the chemical fiber market.
- Downstream does not lack demand; it is waiting for a clear price signal.
- Inventory cycle shifts are often triggered by external variables, not spontaneously from within the industry.
Enterprises at different positions in the chain need differentiated strategies.
