On August 1, the average sales-to-output ratio of polyester filament sample enterprises fell to 33.6%, down 3.8 percentage points from the previous trading day. This figure not only falls below the industry boom line but also reflects the real temperature of terminal demand in the off-season. When the pulse-like restocking from the weekend faded, the market immediately returned to its quiet nature—perhaps this explains the supply-demand contradiction in the chemical fiber industry chain better than any macro data.
Signals Behind the Data
The sales-to-output ratio is a sensitive indicator of the chemical fiber market. A 33.6% ratio means that sample enterprises sold only one-third of their daily output, with the remainder turning into inventory. Among the 26 published samples, the range spans from 0% to 60%, with most concentrated in the low 20%-30% zone, and some enterprises even recorded zero transactions. This divergence reveals the varying resilience of enterprises with different scales and customer structures during the off-season.
More notably, the ratio dropped by 3.8 percentage points month-on-month, indicating that the previous restocking did not generate sustained momentum. Downstream weaving enterprises may have made small purchases last weekend based on low prices or rigid demand, but facing insufficient terminal orders, they prefer to maintain low raw material inventories rather than actively stock up. This "buy on rising, not on falling" mentality is particularly evident during price downtrends.
Market Logic in the Off-Season Adjustment Period
The period from late July to early August is traditionally the off-season for the textile industry. High temperatures, power restrictions, and worker rotations lead to lower weaving operating rates, naturally reducing demand for polyester filament. Meanwhile, upstream PTA and MEG prices fluctuate, providing weak cost support, leaving polyester filament prices with little upward momentum. In this context, the low sales-to-output ratio results from the combined effects of upstream and downstream factors.
For manufacturers, persistently low ratios mean increasing inventory pressure. Some factories may choose to cut prices to boost sales, further depressing market prices and creating a cycle of "price cuts - wait-and-see - further cuts." For buyers, the current market offers bargaining space, but they must be wary of quality risks behind low prices and the possibility of a price rebound later.
Notably, the volatility of sales data also reminds the market that short-term operations need to be more flexible. The past pattern of relying on concentrated restocking to drive markets is unsustainable; the industry is shifting from "pulse trading" to a new normal of "on-demand procurement." This requires enterprises to grasp purchasing rhythms more precisely rather than blindly following trends.
Transmission and Implications for the Industry Chain
The low sales-to-output ratio of polyester filament directly affects the shipment pace of upstream polyester chips. Chip enterprises may face reduced orders and rising inventory, leading to lower operating rates. This pressure transmits upward along the chain, ultimately reflecting in demand expectations for PX and crude oil. Conversely, if terminal textile and apparel exports show pre-season stocking in late August, it could trigger a new round of restocking.
Foreign trade enterprises need to pay special attention to exchange rate fluctuations and international oil price changes. Recently, the RMB exchange rate has shown increased two-way volatility, potentially affecting export order profits; international crude oil prices are uncertain due to geopolitical factors, indirectly influencing chemical fiber costs. It is advisable for foreign trade enterprises to consider exchange rate locking and raw material price linkage clauses when signing long-term contracts to mitigate risks.
Practical Recommendations
For Buyers - Replenish on demand, avoid large one-time stockpiles, and control inventory costs. - Monitor sales-to-output ratio changes; if it remains below 30% for consecutive days, consider negotiating lower prices. - Prioritize suppliers with healthy cash flow and stable operations to reduce supply disruption risks.
For Foreign Trade Enterprises - Closely track exchange rate trends and use tools like forward settlement to lock in profits. - Negotiate price adjustment mechanisms with clients to cope with raw material price fluctuations. - Use the off-season window to optimize product structures and develop high value-added differentiated products.
The current market calm is not without opportunities. For prepared enterprises, the off-season is a perfect time to adjust strategies and build strength. When the sales-to-output ratio data warms up, those who planned ahead will benefit first.
