Polyester Filament Yarn Sales Rate Drops Below 40%: A Cold Look at Downstream Procurement Strategy

On June 22, the average sales-to-output ratio of polyester filament yarn sample enterprises was only 39.5%, a slight increase of 1.3 percentage points from the previous trading day. This means that for every 100 tons of polyester filament yarn produced that day, less than 40 tons were absorbed by the market. The cautious stance of downstream users has evolved from a short-term strategy to a systemic risk-averse behavior.

Signals Behind the Sales Data

The publicly available sales data from 19 sample enterprises showed extreme divergence: the highest reached 120%, while the lowest was 0%. Only one enterprise achieved a ratio above 100%, while eight enterprises had ratios below 30%, accounting for over 40% of the sample. This extreme divergence indicates that the market is not universally weak, but orders are highly concentrated among a few suppliers with cost or channel advantages.

Historically, when the sales-to-output ratio remains below 50% for consecutive days, it usually signals a phase of shrinking terminal demand. Comparing data from the previous trading days (June 18 to 26), the overall ratio did not show a substantial rebound, suggesting that downstream weaving mills' restocking willingness has been persistently suppressed.

Upstream-Downstream Transmission and Cost Game

Polyester filament yarn, as a core raw material for weaving, directly reflects the operating willingness of downstream enterprises. Behind the 39.5% ratio lie several real pressures on weaving mills:
- Weak growth in end-use garment orders, discouraging mills from building raw material inventories
- Increased volatility in raw material prices (PTA, MEG), creating unstable price expectations for filament yarn
- High capital costs, making mills prefer just-in-time purchasing over inventory buildup

This game of 'upstream wants price increases, downstream wants decreases' is unlikely to break on its own without strong demand stimulus. From a cost perspective, high crude oil prices support the polyester chain, but poor transmission to end-users squeezes profit margins in intermediate links.

Long-Term Impact on Procurement Strategy

Persistently low sales ratios will force polyester filament yarn factories to adjust their operational strategies: on one hand, they may cut prices to destock; on the other, they may proactively reduce production to defend price floors. For downstream buyers, this means a short-term price negotiation window, but in the long run, suppliers' survival pressures could pose supply chain stability risks.

Notably, the divergence in sales data also suggests that buyers should reassess their supplier tiers. Enterprises that maintain relatively high sales ratios during weak markets often possess irreplaceable advantages in quality, delivery, or service, and should be prioritized as core suppliers.

Practical Recommendations

For Buyers - Establish a dynamic inventory model: Use the sales ratio as a weekly procurement reference; when the average ratio of sample enterprises falls below 40%, extend procurement cycles to reduce inventory costs - Lock in high-differentiation suppliers: Prioritize enterprises with stable ratios above 60%, as their supply chains are more resilient and they offer higher priority when market conditions reverse - Monitor production cut signals: If the ratio stays below 35% for over a week, factories will likely start production cuts; lock in long-term contracts early to avoid supply disruptions

For Foreign Trade Firms - Leverage exchange rate windows: With low sales ratios, sellers are more willing to negotiate; combine with RMB exchange rate trends to secure better USD pricing terms - Diversify sourcing: Avoid concentrating orders on a single factory with volatile ratios; allocate 60% to main suppliers and 40% to backups - Monitor overseas substitution: If domestic polyester filament yarn prices drop sharply due to destocking, assess the impact on cost competitiveness against Southeast Asian and South Asian rivals, and adjust export pricing strategies accordingly
