Ludwigshafen, Germany / November 2025 — BASF is taking proactive steps to strengthen its position in the global chemical fiber market, which is currently facing structural overcapacities and evolving customer demand. To enhance operational efficiency and long-term competitiveness, the company has announced plans to consolidate its Asian polytetrahydrofuran (PolyTHF®) operations at its Caojing site in China, while phasing out production at its Ulsan site in South Korea by 2026.

This strategic move aligns with BASF’s Winning Ways strategy, aimed at optimizing its global production network and ensuring a more sustainable, efficient, and resilient supply chain.

Following the consolidation, BASF will continue to supply PolyTHF® reliably to customers worldwide through its robust regional production hubs located in Caojing (China), Ludwigshafen (Germany), and Geismar (United States) — offering a combined annual production capacity of 250,000 metric tons.

PolyTHF®, also known as polytetrahydrofuran, is a key intermediate used in the production of elastic spandex and elastane fibers. These materials are widely applied in textiles such as sportswear, swimwear, and underwear, providing stretchability, comfort, and durability.

Through this structural adjustment, BASF reinforces its commitment to sustainable chemical manufacturing, operational excellence, and customer reliability — ensuring that its PolyTHF® value chain remains competitive and future-ready in a challenging global market.
