Test operation of Ulsan plant at the end of this month... ‘Contribute to creating a solid semiconductor ecosystem’
Quick Look
- The anhydrous hydrofluoric acid plant built by BGF Eco Specialty, a subsidiary of BGF Group affiliate KNW, in the Onsan National Industrial Complex in Ulsan will complete construction and begin test operation at the end of this month.
- Anhydrous hydrofluoric acid is a basic material for high-purity fluorine compounds for semiconductor cleaning and etching processes, secondary batteries, and refrigerants.
- It is expected to reduce dependence on foreign countries and contribute to strengthening the competitiveness of the semiconductor ecosystem through domestic production.

Why It Matters
Korea imports 97% of anhydrous hydrofluoric acid from specific countries, so supply chain risks existed, and BGF Group has invested 150 billion won in 2024 to build Korea's largest anhydrous hydrofluoric acid plant in Ulsan.
Test operation of Ulsan plant at the end of this month... “Contribute to creating a solid semiconductor ecosystem”
(Seoul = Yonhap News) Reporter Cho Min-jung = KNW, an affiliate of BGF Group's materials division, announced on the 9th that its subsidiary BGF Eco Specialty's anhydrous hydrofluoric acid production plant will complete construction and begin test operations at the end of this month.
Hydrofluoric acid anhydride is used in the cleaning and etching process of semiconductors and is a basic material for high-purity fluorine compounds such as secondary batteries and refrigerants.
As semiconductor processes become more advanced, purity and stable procurement are directly linked to industrial competitiveness, but in Korea, 97% of anhydrous hydrofluoric acid is imported from specific countries, leading to supply chain risks.
BGF Group decided to invest 150 billion won in 2024 to build Korea's largest anhydrous hydrofluoric acid plant within the Onsan National Industrial Complex in Ulsan, and is expected to be completed in about two years.
A KNW official said, "By localizing the production of anhydrous hydrofluoric acid, a key material in the high-tech industry that was highly dependent on external sources, we will be able to greatly contribute to creating a solid semiconductor ecosystem in Korea. Going forward, we will continue to increase the competitiveness of the Korean industry as a top-tier company representing K-materials, following K-Semiconductor."
BGF Eco Specialty is a subsidiary company 100% owned by KNW, a KOSDAQ listed company, and a grandchild of BGF Eco Materials, the materials division of BGF Group.
