On September 4, the average sales-to-output ratio of polyester filament yarn sample enterprises stood at 21.0%, down 4.8 percentage points from the previous trading day. This figure means that for every 100 tons of polyester filament yarn produced, only 21 tons found buyers, with the rest turning into inventory. This is not a one-day anomaly—sample data show ratios ranging from 0% to 40%, with most enterprises hovering between 10% and 20%, indicating a typical pre-slip market condition. When the sales-to-output ratio stays below 30% for an extended period, cash flow pressure on chemical fiber factories accumulates rapidly, yet downstream weaving mills show no urgency to restock. This supply-demand mismatch reflects a divergence in price expectations: upstream wants to protect profits, while downstream waits for lower prices.
Signals Behind the Sales Data
Polyester filament yarn is a core intermediate product in the textile industry chain, and its sales-to-output ratio directly reflects the warmth of end demand. The 21% ratio is not an isolated event but a concentrated expression of upstream-downstream gaming. The sample data show an uneven distribution: some enterprises achieved 40% ratios, while others recorded 0%, suggesting structural divergence rather than a complete freeze. Notably, downstream users' "resistance to high prices" was the direct driver of sluggish transactions. "High prices" here do not necessarily mean absolute price levels, but rather that relative to downstream weavers' profit margins, polyester filament yarn remains expensive. When terminal garment orders cannot support higher fabric prices, weaving mills can only compress raw material purchases, maintaining production with rigid demand. Once such resistance forms, it often has inertia. Even if upstream attempts price cuts, downstream may continue to wait due to the "buy on rising, not falling" psychology, prolonging the low-ratio period.
Imbalance in Industrial Chain Profit Transmission
The sharp drop in polyester filament yarn sales ratios reflects not just demand issues but also an imbalance in profit distribution across the chain. From PX and PTA to polyester filament yarn, then to fabrics and garments, every segment's profit margins are being squeezed. When terminal consumption growth slows and profits cannot transmit downstream, price support for upstream chemicals becomes fragile. For polyester plants, a ratio below 30% means rising inventory turnover days and increased capital occupation. If this persists, plants may be forced to cut production or discount sales, triggering a new round of price competition. Downstream weaving mills may benefit in the short term from lower raw material prices, but in the long run, upstream losses will lead to supply contraction, eventually pushing raw material prices higher. This "negative feedback" loop is not uncommon in the chemical fiber industry. Previous troughs in 2023 and 2024 were followed by price rebounds, but the rebound strength depended on substantive recovery in terminal demand. Current data show no strong recovery signs in the garment market, so this low-ratio period may last for several weeks.
Implications for Buyers and Foreign Trade Enterprises
For fabric buyers, blindly chasing declines or rises is unwise at this point. Polyester filament yarn prices are on a downward track, but the room is limited because polyester plants' cash cost lines are nearby. It is advisable to purchase in batches on a weekly basis, avoid one-time large orders at fixed prices, and monitor upstream PTA plant maintenance schedules, as these often signal price turning points. Foreign trade enterprises should be wary of exchange rate fluctuations and overseas demand uncertainty. The low sales ratio implies that China's textile competitiveness remains, but export order profits may be eroded by raw material price volatility. It is recommended to include price adjustment clauses in long-term contracts or hedge raw material risks through futures markets.
For Buyers - Purchase in weekly batches to avoid price spikes from large single-day orders - Monitor polyester plant operating rates; if they drop by more than 5%, consider increasing inventory - Sign monthly floating price agreements with suppliers to lock in basis
For Foreign Trade Enterprises - Include raw material price linkage clauses in export contracts to diversify risk - Use polyester filament yarn futures for hedging to lock in costs - Monitor purchasing rhythms of Southeast Asian and South Asian clients; adjust quotation strategies in advance
Every fluctuation in chemical fiber market ratios is a process of rebalancing the industrial chain. The current downturn may be the accumulation phase before the next upswing. The key lies in who can more accurately grasp the rhythm of inventory and prices in this game.
