The price of polyester POY has climbed from 7,000 yuan per ton in late January to 9,325 yuan by mid-March, a gain of over 33% in just two months. This is not an isolated case: nylon, spandex, and chemical intermediates for DWR coatings have also risen sharply, with some varieties jumping 20% in a single day. The shell jacket supply chain is now facing a systemic cost shock originating from crude oil, yet retail prices have been slow to adjust—a lag worth examining.
Cost Structure Determines Sensitivity
Fabric accounts for 60% to 70% of the total cost of a shell jacket, with polyester POY being the key raw material for the main fabric. Industry estimates show that the polyester price hike alone adds nearly 40 yuan to the material cost of a mass-market jacket priced around 500 yuan, and 60 to 100 yuan for mid-to-high-end products above 1,000 yuan. When auxiliary materials such as seam tape and water-repellent agents are included, the per-unit cost increase could be even higher.
For brands, the high proportion of raw material costs means limited price elasticity. But retail prices have not reacted immediately, partly due to inventory buffers: some brands secured raw materials at lower prices earlier, temporarily offsetting the pressure. However, inventories will eventually deplete, and when new batches are produced with higher-priced inputs, autumn/winter products are likely to see price increases or reduced discounts.
The Dilemma of Midstream Enterprises
The bottleneck in cost pass-through lies in the midstream fabric and garment manufacturing segments. A fabric exporter reported that polyester product quotes have risen by up to 15%, but foreign trade orders are typically priced months in advance, making contract prices difficult to change. The profit gap between rising upstream raw material costs and fixed downstream selling prices must be absorbed by the fabric company, significantly squeezing margins.
This contradiction is common in the textile and apparel industry: upstream chemical raw materials fluctuate with international situations and crude oil supply-demand dynamics, while downstream order cycles are relatively fixed. When raw material prices surge during the contract period, midstream companies face a dilemma: raising prices may lose customers, while not raising prices means absorbing losses. Small and medium-sized factories, with limited bargaining power and hedging tools, often suffer the most from volatility.
Chain Reactions in Industrial Clusters
Industrial clusters such as Keqiao and Shengye, which specialize in chemical fiber fabrics, feel the impact most directly. Local traders report that polyester filament quotes are updated almost daily, with some specifications seeing two price changes in one day. Fabric mills are forced to adopt smaller, more frequent purchasing strategies to avoid high inventory risks, which in turn increases production costs and management complexity.
Meanwhile, the growing popularity of functional outdoor apparel has expanded the market, but it also exposes the supply chain's heavy reliance on petrochemical raw materials. The waterproof breathable membranes and seam tapes used in shell jackets are all derived from petroleum, meaning the cost shock is not limited to a single fiber but affects the entire chain. Unless companies in these clusters establish effective raw material inventory management and price hedging mechanisms, future fluctuations will continue to test their operational resilience.
