When the same specification of a product is quoted at an identical price across three industrial hubs thousands of kilometers apart, it is rarely a coincidence. It signals that the industry has entered a phase of equilibrium. On September 24, 2026, spandex 40D bright filament was listed at RMB 29,000 per tonne in Wenzhou, Xinxiang and Xiamen, with Huafeng Chemical, Xinxiang Chemical Fiber and Xiamen Lilong quoting exactly the same figure. Such lockstep pricing has been uncommon in the spandex market over the past two years, indicating that leading producers now share a highly converged view of the cost floor.
The Cost Logic Behind Flat Pricing
The core raw materials for spandex are BDO (1,4-butanediol) and PTMEG, which together account for more than 60% of production costs. Although BDO prices have fluctuated in 2026, they have generally remained near the break-even line, providing rigid support for spandex quotes. When three companies based in Zhejiang, Henan and Fujian give the same price, it suggests their respective raw material procurement costs and processing expenses have narrowed to a very tight range.
From an industrial belt perspective, Wenzhou benefits from Huafeng Chemical's integrated layout and self-supply of PTMEG; Xinxiang Chemical Fiber leverages its central location and large-scale capacity to control costs; Xiamen Lilong occupies a niche in the textile cluster of southern Fujian. The convergence of quotes across these three locations reflects how leading players have regained pricing power after industry-wide capacity consolidation. For downstream weavers, this means cross-regional price arbitrage is unlikely to yield meaningful discounts in the short term.
Why Demand Cannot Support a Price Hike
The other side of flat pricing is weak demand. Spandex is mainly used in sportswear, underwear and medical bandages, so downstream activity directly determines purchasing willingness. In the third quarter of 2026, operating rates at domestic weaving mills remained generally low, with some small and medium-sized factories producing to order and becoming more cautious about restocking spandex. On the export front, the recovery of European and American orders has been slower than expected, while Southeast Asian re-export trade has diverted some demand.
In this supply-demand landscape, spandex prices lack the momentum for an upward breakout, but the cost line caps the downside. For buyers, RMB 29,000 per tonne is neither a bottom-fishing price nor a chase-high price, but a mid-range level that requires judgment based on one's own inventory and order rhythm.
Transmission Effects Up and Down the Chain
Upstream BDO producers have little room for significant concessions in the short term, because once spandex prices fall below the cost line, leading producers can rebalance the market by cutting output to support prices. Downstream fabric mills face a dilemma: accepting the current price means compressed margins, while waiting could mean missing the pre-peak-season stocking window.
Exporters need to pay special attention to the combined impact of exchange rates and shipping costs. Spandex exports are mostly denominated in US dollars, so RMB exchange rate fluctuations directly alter actual profits. Meanwhile, European and American labeling requirements for elastane content in textiles are tightening, so buyers should confirm suppliers' test reports and compliance documents.
Practical Recommendations
For Buyers - Build positions in batches at the current level rather than locking in a single price, preserving room for subsequent negotiation - Prioritize long-term agreements with suppliers that have integrated production capacity to hedge cost volatility - Monitor monthly BDO settlement prices as a leading indicator of spandex price direction
For Exporters - Leave a 3%-5% buffer for exchange rate fluctuations in quotations to avoid profit erosion - Verify spandex suppliers' OEKO-TEX or REACH compliance credentials to reduce customs clearance risks - For European and American orders, communicate with customers in advance about updated labeling requirements for elastane content
Overall, spandex 40D hovering at RMB 29,000 per tonne is a microcosm of the industry transitioning from overcapacity to rational competition. The future price direction depends on two variables: whether BDO costs can loosen and whether weaving orders will recover in the fourth quarter. Before clear signals emerge, procurement strategies should be steady rather than aggressive.
