Polyester Filament Yarn Sales Rate Stays Low: Signals of Inventory Pressure and Weak Downstream Demand

Public data from the chemical fiber industry on July 17 shows that the average sales-to-production ratio of polyester filament yarn (PFY) sample enterprises was only 33.0%, down 0.1 percentage points from the previous trading day. This figure is not only below the industry's healthy level (typically above 60% is considered normal) but also means that nearly 70% of the day's output failed to translate into actual sales, directly adding to inventory accumulation.

Industry Signals from Low Sales-to-Production Ratio

The sales-to-production ratio is a core indicator of supply-demand balance in the chemical fiber market. A ratio of 33.0% clearly indicates a significant oversupply situation. Looking at specific sample enterprise data, the ratios are widely dispersed, ranging from a low of 0% to a high of 60%, with most enterprises hovering between 20% and 35%. This distribution suggests that the problem is systemic rather than isolated to a few firms.

The direct consequence of a low sales-to-production ratio is rising inventory pressure. For chemical fiber companies, inventory not only ties up capital and storage resources but also carries the risk of product degradation. Polyester filament yarn stored for too long may develop color differences, reduced strength, and other issues, ultimately forcing price reductions and further squeezing profit margins.

Deeper Causes of Weak Downstream Demand

The primary downstream sectors for PFY are textile fabrics and garment production. The current low ratio reflects cautious sentiment in the end-consumer market. On one hand, summer is traditionally a low season for the textile industry, with high temperatures leading some weaving mills to reduce output or shut down. On the other hand, global macroeconomic uncertainties are suppressing brand owners' purchasing intentions, which translates into reduced order volumes and longer lead times in the fabric segment.

It is worth noting that low buying sentiment is not a short-term phenomenon. Similar data from July 15 and 16 show that the ratio has been persistently weak, indicating sustained demand weakness. This means chemical fiber companies cannot rely on a short-term rebound and must address the situation through inventory management and product mix adjustments.

Transmission Effects Along the Supply Chain

The low PFY sales-to-production ratio will propagate upstream and downstream along the supply chain.

• Upstream raw materials: PTA and MEG are the main inputs for PFY. Reduced production or price cuts by PFY plants will lower their procurement volumes of PTA and MEG, affecting the operating rates and profits of petrochemical companies. If PFY inventories cannot be digested, PTA prices may face downward pressure.
• Downstream weaving: Weaker PFY prices provide cost reduction opportunities for weaving mills, but only if they have sufficient orders. The current low ratio means weaving mills are also facing demand shortages, so the benefit of lower costs is unlikely to translate into profit growth.
• Trade and distribution: Intermediaries and traders tend to destock rather than replenish in a low-ratio environment, further tightening market liquidity.

Practical Recommendations

For Buyers - Take advantage of current weak PFY prices to negotiate short-term framework agreements with suppliers, locking in low-cost supply. However, avoid large-scale stockpiling in case prices fall further. - Monitor PTA futures price trends. If raw material prices drop significantly, PFY prices may soften further, presenting a better purchasing window. - Negotiate with weaving mills for phased delivery to reduce your own inventory risk, while using the PFY price weakness to bargain for more favorable procurement terms.

For Foreign Trade Companies - Closely track RMB exchange rates and textile capacity dynamics in Southeast Asia. The current weakness in domestic PFY prices could enhance the price competitiveness of Chinese PFY in international markets, but be alert to order diversion from local capacity expansion in Southeast Asia. - Proactively offer PFY quotations based on current low prices to overseas clients, aiming to secure long-term orders. At the same time, monitor trade policy changes in target markets, such as potential anti-dumping investigations. - Use the off-season period to strengthen client relationships and gather market feedback, preparing for restocking ahead of the peak season in the second half of the year.
