On August 1, trading in the polyester filament market turned notably subdued, with the average sales-to-output ratio among sampled enterprises falling to 33.6%, down 3.8 percentage points from the previous trading day. This figure not only sits below the industry's prosperity line but also reveals obvious fatigue among downstream buyers after a concentrated restocking over the weekend. As the restocking impulse fades, the market quickly reverts to a wait-and-see stance, with divergence in sales data hinting at varying order pressures across enterprises of different scales.
Signals Behind the Data
Looking at the day's sales data, the ratio ranged from 0% to 60%, with 60% appearing twice and 0% once, while most values clustered between 20% and 30%. This dispersed distribution indicates that not all enterprises faced the same demand contraction—some maintained relatively high sales, while others saw almost no transactions. The 0% ratio, meaning zero sales for the day, is rare in normal conditions and may reflect price negotiation standoffs or the absence of key customers.
The decline in the sales ratio is not an isolated event but a direct consequence of demand being overdrawn by earlier restocking. Over the weekend, some downstream users made concentrated purchases, releasing short-term demand in advance, which led to a significant drop in buying enthusiasm at the start of this week. This "pulse-style" procurement pattern is not uncommon in the chemical fiber market, but the contrast between the strength of the restocking and the speed of the subsequent retreat reveals that terminal orders have not formed sustained support, leaving the market in a weak equilibrium.
Industrial Transmission and Inventory Pressure
Fluctuations in the polyester filament sales ratio directly affect price expectations for upstream polyester chips, PTA, and MEG. When filament enterprises face sluggish sales, their operating rate adjustments transmit to the raw material side, exacerbating the supply-demand loose pattern across the polyester chain. Currently, polyester filament inventories are already at medium-to-high levels; if the sales ratio continues to languish, enterprises may be forced to cut prices to stimulate sales, thereby compressing processing margins and potentially triggering a negative feedback loop—where falling prices further dampen downstream purchasing intentions.
For downstream weaving enterprises, the weakening sales data suggests that raw material procurement windows may be postponed. Under expectations of lower prices, weaving mills tend to maintain minimal raw material inventories, purchasing on a need-basis rather than in bulk. This mindset, in turn, intensifies the difficulty for filament enterprises to move goods, creating a "the more it falls, the less they buy" cycle. Therefore, polyester filament prices are likely to face downward pressure in the short term, but the decline may be limited by cash flow costs, with a gradual drift expected rather than a sharp crash.
Regional and Product Divergence
From the distribution of sales data, enterprises with high ratios (e.g., 60%) are likely concentrated in textile clusters such as Shengze and Changxing, where downstream looms operate at relatively stable rates, ensuring rigid demand for raw materials. In contrast, enterprises with low ratios may cater more to trader groups, which are more susceptible to speculative demand swings. Additionally, different specifications of polyester filament (e.g., POY, FDY, DTY) show varying demand, with regular varieties weakening while differentiated products (such as cationic or flame-retardant) retain some support, reminding enterprises to flexibly adjust their product mix.
Practical Recommendations
For Buyers - Control raw material inventory to 7-10 days of usage, avoiding large stockpiles during a downward price channel; adopt a hand-to-mouth strategy to reduce markdown risk. - Monitor late-month and early-next-month restocking windows, when some mills may offer concessions to meet monthly sales targets, providing opportunities to lock in lower prices. - Strengthen communication with direct large suppliers to negotiate more flexible settlement terms (e.g., deferred pricing) to cope with short-term price volatility.
For Foreign Trade Enterprises - When quoting export orders, reference current sales ratios and inventory data to reserve room for price adjustments, avoiding contract losses due to raw material declines. - Prioritize differentiated, high value-added product orders to reduce competition in regular varieties, using technical barriers to stabilize profits. - Monitor overseas restocking cycles and, considering RMB exchange rate trends, consider hedging tools when signing contracts to mitigate dual risks of currency and raw material price fluctuations.
In summary, the polyester filament market is shifting from a "restocking boom" to a "destocking" phase, and the decline in the sales ratio reflects a rational market correction. All parties in the chain should maintain caution, buying time, and awaiting signals for the next demand upturn.
