On July 10, the average sales-to-production ratio of sampled polyester filament yarn enterprises dropped to 35.5%, down 4.9 percentage points from the previous trading day. This data, from industry-wide public statistics, covers the daily sales versus output comparison of major polyester filament yarn producers. After a concentrated period of replenishment, downstream users quickly shifted to a wait-and-see stance, significantly reducing market trading activity.
Behind the Sharp Decline in Sales Ratio
The sales-to-production ratio is a key indicator of short-term supply-demand balance in the chemical fiber market. A ratio of 35.5% means only about one-third of the day's output was absorbed by the market, with the rest adding to inventories. Looking at the specific data from sampled enterprises, the distribution was highly uneven: the lowest was 0% and the highest 70%, but most fell in the 20% to 35% range. This 'two-speed' phenomenon suggests that downstream demand is not universally weak but highly selective—some specifications or quality grades still enjoy relatively stable orders.
The rapid exit of downstream users after concentrated replenishment is the direct cause of this decline. In the chemical fiber industry, weaving mills typically adopt a 'small batch, multiple order' procurement strategy to cope with uncertainties in end-use orders. Once a round of stockpiling is completed, they pause purchasing, waiting for price signals or order confirmations. This 'replenish-then-wait' cycle is more pronounced during off-seasons. July is traditionally a low season for textiles, with weak consumer demand for apparel and home textiles, leading to generally low operating rates among downstream weaving mills, further suppressing raw material procurement.
Transmission Effects Along the Supply Chain
A low sales ratio first impacts the inventory levels and cash flow of polyester filament yarn producers. If this trend persists, companies may face inventory pressure, prompting price cuts or production cuts to rebalance supply and demand. For upstream PTA and MEG suppliers, slower procurement by polyester yarn mills will compress their shipment pace, creating a negative transmission chain.
For downstream weaving and dyeing mills, the current market environment offers short-term bargaining power. Softer raw material prices can help reduce production costs. However, it's important to note that a low sales ratio does not necessarily mean prices will fall—if upstream supply contracts or costs rise, prices may remain elevated. Therefore, buyers should monitor price movements of PTA and MEG, as well as any operating rate adjustments by polyester yarn producers.
From a regional perspective, major polyester filament yarn production and consumption areas like Shengze, Changxing, and Xiaoshan may feel more pronounced shipment pressure in the near term. Weaving mills in these areas typically have close supply ties with local chemical fiber plants, so changes in the sales ratio directly reflect in daily order volumes and inventory turnover.
Industry Trend Assessment and Operational Recommendations
Overall, the short-term fluctuation in polyester filament yarn's sales ratio is a normal off-season phenomenon, but the 35.5% figure has touched a recent low range. Market direction over the next one to two weeks will depend on two key variables: whether end-use orders show seasonal improvement in late July, and whether upstream raw material prices provide directional guidance. If PTA prices strengthen due to crude oil volatility or increased maintenance, polyester yarn prices may find support, stimulating downstream replenishment. Conversely, if raw materials remain weak alongside sluggish demand, the sales ratio may continue to hover at low levels.
For Buyers - Adopt a 'procure-as-needed, small-batch' strategy to avoid inventory build-up from concentrated buying, and use the wait-and-see period to negotiate more flexible payment or delivery terms with suppliers. - Monitor daily price changes of PTA and MEG. If upstream costs drop significantly, consider delaying purchases to wait for price adjustments in polyester yarn.
For Producers - Adjust operating rates dynamically based on sales ratio data to prevent rapid inventory accumulation. Prioritize production of high-value-added or differentiated products to maintain margins. - Strengthen communication with key downstream customers to understand their order schedules and stocking plans, enabling proactive production scheduling and reducing passive inventory risks.
The sharp drop in the polyester filament yarn sales ratio is a microcosm of the supply-demand tug-of-war in the chemical fiber chain during the off-season. For industry practitioners, understanding the logic behind the data is more valuable than focusing on a single day's fluctuation.
