The pricing power in the polyester filament market is slipping away from sellers. On September 4, the average sales-to-production ratio of sampled enterprises was only 21.0%, down 4.8 percentage points from the previous trading day. This figure implies that for every 100 tons of polyester filament produced, only about 21 tons found buyers, with the rest adding to inventory pressure. When the ratio stays below 30% for consecutive days, the market typically enters a buyer-determined pricing zone.
Signals Behind the Numbers
Public data on the sampled enterprises shows clear divergence: some firms reported ratios around 40%, while several recorded zero, and many hovered in the 10%-20% range. This divergence is not random—it reflects differences in product mix, customer loyalty, and pricing strategies. However, the 21% average has touched a yearly low, indicating significantly reduced market activity compared with the same period last year.
More concerning is the downstream reaction. Reports indicate persistent resistance to high prices, with buyers sticking to rigid demand and avoiding proactive stockpiling. This has led to sluggish trading—not because demand is absent, but because it is suppressed by price levels. When raw material price increases exceed what downstream orders can bear, weaving mills prefer to cut operating rates rather than buy expensive inventory. This 'high-price asphyxiation' is not new to the chemical fiber chain, but its duration has exceeded most participants' expectations.
Transmission Along the Chain and Regional Responses
The price standoff stems from a tug-of-war between upstream cost support from PTA and MEG and weak downstream demand. In the polyester chain, profit margins from PX to PTA to filament have been squeezed to multi-year lows, prompting mills to defend prices. Yet terminal orders for apparel and home textiles remain lackluster, especially in export markets where currency fluctuations and shipping uncertainties have slowed procurement.
Observations from major weaving hubs like Shengze, Changxing, and Xiaoshan indicate that fabric mills are adopting a 'buy-as-needed' strategy, keeping raw material inventories at just 3-5 days of consumption, well below the normal 7-10 days. This destocking behavior exacerbates the sales pressure on polyester plants. Some factories have begun maintenance or reduced operating rates to balance supply and defend price floors, but the effectiveness remains to be seen.
For traders, there is little arbitrage opportunity. Futures-spot spreads have narrowed, basis volatility has decreased, and short-term operations have become more difficult. Downstream fabric mills are factoring raw material price volatility into their quotes, lengthening price negotiations for new orders. The entire chain's bargaining focus is shifting from 'cost-plus' to 'demand-based' pricing.
Future Outlook
In the short term, a rapid recovery in the sales-to-production ratio is unlikely. On one hand, terminal consumption is in a pre-season lull before the traditional peak; on the other, overseas markets lack purchasing impetus due to high interest rates and inventory digestion. Unless upstream feedstock prices correct significantly, downstream resistance will persist. If the ratio stays below 25%, inventory pressure will build, potentially triggering price cuts and accelerating declines.
From a medium-term perspective, industry consolidation signals deserve attention. The low-profit environment is eliminating outdated capacity, and some small and medium polyester plants face cash flow strain. For downstream buyers, this may imply a more concentrated supplier base and improved long-term supply stability. However, fabric mills relying on low-cost raw materials must remain vigilant about price fluctuation risks.
