21.0% - that was the average sales-to-production ratio of polyester filament sample enterprises on September 4, down 4.8 percentage points from the previous trading day. This number means that for every 100 tons of polyester filament produced that day, only 21 tons found buyers. When the sales-to-production ratio lingers at low levels for consecutive days, the supply-demand balance in the chemical fiber industry chain is undergoing subtle shifts.
What the Data Tells Us
A single day's figure might be coincidental, but combined with recent market performance, the 21.0% ratio is not an isolated case. On that day, the ratio ranged from 0% to 40% among sample enterprises, with most concentrated in the 10%-20% range, and a few even reported zero transactions. This extreme divergence indicates that buyers have not completely left the market; rather, they are highly selective on price, only willing to purchase goods with outstanding cost-performance.
The downstream users' 'resistance to high prices' is the direct driver of the sluggish market. Resistance does not mean refusal to buy, but unwillingness to pay current prices. When polyester filament prices remain relatively high and terminal orders are insufficient to support price pass-through, downstream weaving enterprises tend to reduce raw material inventories and purchase on a need-basis. This 'buy as you use' strategy, in turn, exacerbates the inventory pressure on polyester plants, creating a negative feedback loop.
Upstream-Downstream Game: Who Waits for Whom?
Polyester filament sits in the middle of the polyester industry chain, with upstream PTA and MEG, and downstream weaving and apparel. The current situation essentially reflects a mismatch of price expectations between upstream and downstream. Upstream polyester plants are reluctant to cut prices due to cost support, hoping to maintain profit margins; downstream users, burdened by weak terminal demand and high finished goods inventories, refuse to accept high-priced raw materials. Both sides are waiting for the other to make the first move.
From the cost side, recent PTA and MEG prices have not fluctuated significantly, and the cash flow pressure on polyester plants is still manageable, giving them the confidence to hold prices. However, the persistently low sales-to-production ratio is eroding this confidence - inventory days are passively rising, and storage costs and capital occupation pressures are increasing day by day. Once cash flow pressure exceeds a critical threshold, some plants may resort to price cuts to relieve inventory pressure, which could trigger a chain reaction.
Industry Impact: From Sluggish Transactions to Structural Adjustment
In the short term, the polyester filament market may continue the pattern of 'price stalemate and weak transactions.' For buyers, this means they can continue to wait for a better entry point; but for plants, inventory pressure will gradually accumulate, especially those with sales-to-production ratios of 0% or 10%, which may face greater operational risks.
Notably, such market pressure may also force structural adjustments in the industry. High-cost, low-efficiency capacity will be phased out faster, while enterprises with cost advantages and product differentiation capabilities will better weather fluctuations. Historical experience shows that each trough in sales-to-production ratio accelerates industry consolidation, laying the foundation for the next cyclical upturn.
Practical Recommendations
For Buyers - Avoid bulk stockpiling during the price stalemate; maintain a safety inventory of 5-7 days to handle unexpected orders. - Closely monitor polyester plants' inventory and sales-to-production data; if the ratio stays below 20% for three consecutive days, it may signal price easing, and you can consider replenishing purchases opportunely. - Establish flexible pricing mechanisms with suppliers, such as base price plus floating clauses, to reduce unilateral price risks.
For Plants - Strictly control production volume, avoiding blind full-capacity operation when the sales-to-production ratio is low; prioritize digesting existing inventory. - Strengthen product structure optimization by increasing the proportion of differentiated products (e.g., cationic, flame-retardant varieties) to reduce homogeneous competition. - Utilize futures or forward contracts for hedging to lock in some product selling prices and mitigate the impact of price fluctuations.
The polyester filament market is at a sensitive juncture. The 21.0% sales-to-production ratio is not just a daily figure but a concentrated reflection of market sentiment. In the coming weeks, the upstream-downstream game will determine the price direction. Whether you are a buyer or a seller, staying sensitive to data and managing inventory rationally are key to navigating the cycle.
