Hyosung TNC Corporation (ISIN KR7298020009) began commercial bio-BDO production in Vietnam on October 19, 2026, as part of a planned US$1 billion investment supporting an initial annual capacity of 50,000 metric tons. The announcement gives the synthetic-fiber producer a concrete expansion milestone while its second-quarter revenue had already risen 27.9 percent year over year.

Vietnam adds a new production link

According to Placera on October 19, 2026, Hyosung TNC started bio-BDO production in Vietnam and connected sugarcane-derived feedstock with bio-based spandex manufacturing. The facility initially produces 50,000 metric tons annually, while the planned investment could lift capacity in phases to 200,000 metric tons.

The project matters because bio-BDO replaces fossil-based feedstock while preserving the performance of finished spandex. The company also plans to supply bio-based intermediates for thermoplastic polyurethane and biodegradable plastics, extending the project beyond textiles.

What does 50,000 metric tons change?

The scale creates a measurable operating platform rather than a product announcement alone. Hyosung TNC can connect raw-material production, intermediate processing and spandex output within southern Vietnam, which may reduce transport requirements and improve supply reliability, according to the company statement carried by Placera.

Three dated developments

On September 28, 2026, NH Investment and Securities cut its Hyosung TNC target from KRW 470,000 to KRW 450,000 while estimating third-quarter operating profit at KRW 110.5 billion, as reported by Gate News. On October 14, 2026, Hyosung TNC was reported to have developed eight new high-performance fabrics, according to ATS View. On October 19, 2026, the company began the 50,000-metric-ton bio-BDO operation in Vietnam.

Dates for the next filings

Hyosung TNC is scheduled to present at Functional Fabric Fair in Portland from October 27 to October 28, 2026, according to Placera. The next third-quarter filing deadline is November 16, 2026, according to ATS View.

Quarterly figures set the benchmark

Hyosung TNC reported second-quarter 2026 revenue of KRW 2.42 trillion, up 27.9 percent from the year-earlier quarter, while operating profit reached KRW 188.8 billion with a 7.8 percent margin, according to ATS View. That result compares with KRW 2.09 trillion of revenue and KRW 86.2 billion of operating profit in the first quarter of 2026, leaving the bio-materials project to prove its contribution against an improving operating base.
