Polyester Filament Yarn Sales-to-Production Ratio Plunges: Supply-Demand Rebalancing Behind the Market Cooldown

On August 1, trading in the polyester filament yarn market suddenly cooled, with the average sales-to-production ratio of sample enterprises falling to 33.6%, down 3.8 percentage points from the previous trading day. This figure signals typical demand exhaustion after weekend restocking and suggests short-term price pressure for polyester filament yarn.

Market Background

The sales-to-production ratio is a core indicator measuring daily sales against output. A 33.6% average means only about one-third of the day's output was absorbed by the market, with inventories accumulating at the enterprise level. Public data shows significant divergence among enterprises: the lowest ratio was 0%, the highest 60%, with most falling in the 20%-40% range, reflecting differences in order-taking capabilities across company sizes.

Weekend concentrated restocking by some users exhausted early-week purchasing demand. Market enthusiasm was generally low, transactions were quiet, and sales remained flat. This pulsed purchasing pattern is not uncommon in the chemical fiber market, but the sharp decline this time suggests downstream weaving enterprises already have sufficient inventory and lack short-term replenishment momentum.

Industry Impact

The lower sales-to-production ratio directly pushes up social inventories of polyester filament yarn. If this trend continues, polyester plants may resort to price discounts to ease inventory pressure, squeezing their own profit margins. For upstream PTA and MEG, demand support weakens, and raw material prices may fall in tandem, forming a negative feedback loop across the chain.

For downstream weaving enterprises, this is a typical buyer's market. Raw material procurement can be more deliberate without chasing highs, but they must guard against inventory depreciation risks from rapid price declines. Foreign trade firms face dual challenges of order delivery cycles and raw material price volatility; if filament yarn prices fall, the competitiveness of export quotes may improve.

Notably, the fluctuation in sales-to-production data also reflects a lack of stable market expectations. With the peak season not yet arrived and cost-side support insufficient, the polyester filament yarn market is likely to maintain a range-bound pattern.

Practical Recommendations

For Buyers - Staggered purchasing: Avoid large one-time purchases; split procurement into 3-5 batches based on production plans to reduce price fluctuation risk. - Monitor inventory indicators: Track weekly sales-to-production ratios and inventory days of leading enterprises; if the ratio stays below 40% for consecutive weeks, consider delaying purchases. - Lock in long-term contracts: Sign floating-price contracts with suppliers, converting part of purchases to basis pricing to smooth costs.

For Foreign Trade Firms - Quotation strategy: During price downturns, adopt a formula-based quotation of "raw material cost + processing fee" and include price adjustment clauses. - FX hedging: If settled in USD, watch RMB exchange rate fluctuations and use forward settlement tools to lock in profits. - Order rhythm: Encourage customers to place smaller, staggered orders to shorten delivery times, reduce raw material inventory holding, and improve capital turnover efficiency.
