Hyosung TNC was spun off in 2018 during Hyosung Group's holding-company restructuring and holds the world's top market share in spandex.
Its business splits broadly into textiles (spandex and its raw material PTMG, plus nylon and polyester yarns) and trading/other operations (composite trading including steel); the Korea Economic Daily reported in a May 2026 analysis that spandex and PTMG account for roughly 40% of revenue and about 70% of operating profit.
Consistent with that, in 2Q26 the textile segment posted KRW 165.2bn in operating profit versus KRW 23.6bn for trading and other operations (Korea Economic Daily, Aug 3, 2026).
Key brands include the functional spandex line Creora and the recycled fiber line regen, supplied by end use across sportswear, swimwear, denim and diaper applications.
Production is spread across Korea (Gumi), China (Jiaxing, Zhuhai, Quzhou, Ningxia), Vietnam (Dong Nai), India, Turkey and Brazil, allowing region-specific responses to demand, tariffs and logistics.
In 2025 the company acquired Hyosung Chemical's specialty-gas business for KRW 920bn and launched the subsidiary Hyosung Neochem, saying that combined with its Quzhou facility it secured NF3 capacity of 11,500 tonnes per year.
Hyosung Neochem's main customers are reported to include semiconductor makers Samsung Electronics and SK Hynix and display makers LG Display and Samsung Display, adding semiconductor materials to the legacy textile and trading mix.
On competition, China's spandex market has been reported as an oligopoly in which the top five players, Hwafeng Chemical, Hyosung TNC, Huahai, Xinxiang and Yantai, hold about 80% of capacity, while Lycra, with a 6-7% share, influences the landscape through supply relationships with brands such as Lululemon and Nike.
As a result, earnings are increasingly determined by spandex prices and raw-material spreads together with the performance of the newly added specialty-gas and bio-materials operations.
