On August 28, the polyester filament market in Shengze presented a rare picture of price freeze: from 40D to 300D FDY regular specifications, ex-works prices remained unchanged for two consecutive days, and DTY series were equally flat. Yet this apparent calm masked sluggish trading, with most mills keeping quotes flat to move inventory and a few polyester plants quietly cutting prices. The coexistence of flat prices and shrinking volumes indicates a market in a pre-directional standoff.
Three Signals Behind the Price Plateau
Look at the data first. A major mill in Wujiang quoted FDY 50D/24F at 10,000 yuan/ton, Shenghong Chemical at 9,900, and Xiaoshan Rongsheng 50D/48F at 10,000 — all unchanged since the 27th. But price gaps of 100-200 yuan/ton across origins reveal divergences in inventory and cash flow pressures. Notably, FDY full-dull series commanded a premium of 2,300 yuan/ton over semi-dull for 40D/48F, indicating differentiated products still hold pricing power.
Price freeze does not mean supply-demand balance. Downstream weaving and texturizing mills saw operating rates rise modestly, but purchasing slowed significantly, with volumes staying low. This combination of high operating rates and low procurement suggests that end-order transmission has not yet occurred—mills are running production but hesitate to stock raw materials. Softening feedstock costs further dampened restocking appetite, and expectations for the peak season remain muted.
Supply-Chain Transmission: The Domino Effect of Cost Easing
Weakening upstream raw materials are the biggest variable in the polyester filament market. As PTA and MEG prices drift lower, polyester mills' processing margins compress because filament prices have not followed suit. In this scenario, mills are eager to sell, but production-to-sales ratios vary widely—major mills hold reasonable inventories, while smaller ones face greater destocking pressure.
For downstream weavers, lower raw material prices are ostensibly beneficial, but the "buy on rising, not falling" mentality keeps buyers on the sidelines. Their key question: will prices fall further? If feedstocks continue to weaken, filament prices will likely catch down, making inventory hoarding a risky bet. This self-reinforcing expectation further suppresses volumes.
As a major polyester filament distribution hub, Shengze's price action often serves as a bellwether. The current standoff reflects a broader sentiment across the Jiangsu-Zhejiang polyester chain—everyone is waiting for a clear directional signal, whether from crude oil, PTA plant maintenance, or a tangible recovery in end orders.
Outlook: Weak Adjustment More Likely Than Rebound
Given the current supply-demand landscape, the polyester filament market is not optimistic. Rising operating rates mean sustained supply pressure, while demand is unlikely to expand given low peak-season expectations. If costs continue to ease, downward price pressure will intensify. A weak adjustment in price centers is expected in the near term, but the magnitude may be limited—major mills with healthy inventories lack the incentive for aggressive price cuts.
For buyers, this is not the time to aggressively stock up. A "small-lot, frequent-purchase" strategy can mitigate price volatility risk. Monitor PTA trends; if PTA shows signs of stabilization, filament prices may follow. For exporters, exchange rate fluctuations and overseas demand recovery are more critical variables; minor filament price adjustments have limited impact on export order profits, but watch for customer price pressure.
