UNID

What UNID does

UNID is a South Korea-based inorganic chemical manufacturer founded in 1980 and listed on KOSPI (ticker 014830). The company operates an electrolytic chlor-alkali production platform converting potassium chloride (KCl) into potassium hydroxide (KOH) and potassium carbonate (K2CO3), with chlorine, hydrochloric acid, hydrogen, and sodium hypochlorite produced as byproduct chemicals. UNID holds approximately 40% global market share in KOH production and operates 720,000 tons of combined capacity across its Ulsan, Korea plant (400,000 tons after the 2023 expansion) and three China plants — UJC (Zhenjiang, Jiangsu), OJC (Taixing, Jiangsu), and UHC (Yichang, Hubei, operational January 2025 at 90,000 tons/year).

The company serves enterprise B2B customers across five primary verticals: agriculture (fertilizers and pesticide raw materials), petrochemicals (polymerization catalysts for ABS, SBR, latex), electronics and semiconductors (KOH for wafer etching and photovoltaic manufacturing), water treatment (chlorine and sodium hypochlorite for disinfection), and pharmaceuticals/cosmetics (high-purity alkali catalysts). Approximately 90% of Korean production is exported to over 90 countries through dedicated regional sales offices covering Southeast Asia, Europe, South America, Southwest Asia, Africa/Middle East, North America, Australia, Japan, and domestic Korea. Products are sold under direct enterprise contracts via regional sales managers with no public pricing.

UNID has pursued an active strategic pivot under CEO Lee Woo-il (appointed March 2023) toward next-generation energy and ESG businesses alongside its core chemicals franchise. The company has invested approximately 90 billion KRW in Solibers (solid-state battery electrolytes) and 140 billion KRW cumulative in Rebest (flexible secondary batteries), issued 154 billion KRW in exchangeable bonds for water electrolysis and carbon capture investments, and developed proprietary carbon capture technology with KAIST now being deployed in Boryeong City's Carbon Neutral Leading City project. The board business was spun off as UNID btplus in November 2022 to focus capital on chemicals and new energy. The 2030 corporate vision targets 3.5 trillion KRW in revenue versus 1.338 trillion KRW in 2025.

Broad incumbents

• Solvay SA: Solvay produces soda ash, sodium bicarbonate, and chlor-alkali derivatives for industrial customers globally. It overlaps with UNID in basic inorganic commodity chemicals and shares the same industrial B2B sales motion into glass, detergents, and water treatment.
• Dow Inc. Dow is a global chemical major with substantial chlor-alkali and basic inorganic chemical output serving agriculture, packaging, and electronics end markets. As a broad incumbent, Dow competes with UNID in several inorganic chemicals and water treatment adjacencies despite its much larger and more diversified portfolio.
• Occidental Chemical (OxyChem): OxyChem, the chemicals subsidiary of Occidental Petroleum, is one of the largest US producers of chlor-alkali products including chlorine, caustic soda, and chlorovinyls. While broader than UNID and integrated with upstream oil/gas, its chlor-alkali operations compete directly with UNID globally.

Regional players

• LG Chem: LG Chem is Korea's largest chemical company with a diversified portfolio spanning basic chemicals, advanced materials, and battery materials. Its basic chemicals segment and Korean operating footprint make it a relevant regional peer for revenue mix benchmarking and capital allocation comparison.
• Asahi Kasei Corporation: Asahi Kasei is a Japanese chemical and material company with a chlor-alkali and basic inorganic chemicals business serving semiconductor, electronics, and industrial customers across Asia. Its caustic/chlor-alkali footprint and regional Asia positioning make it a directly comparable Korean/Japanese competitor.
• Hanwha Solutions: Hanwha Solutions is a Korean chemical company with overlapping chlor-alkali and basic inorganic chemical operations and a shared domestic Korean customer base. It is a relevant regional benchmark for pricing power and capacity in the Korean caustic/chlor-alkali market where UNID operates its Ulsan plant.

Direct peers

• Olin Corporation: Olin is one of the world's largest integrated chlor-alkali producers, manufacturing chlorine, caustic soda, hydrochloric acid, and sodium hypochlorite. It is directly comparable to UNID in product mix (alkali + chlor-alkali byproducts), manufacturing process (electrolysis), and B2B industrial customer base.
• INEOS Group: INEOS is a global chemical manufacturer with a large chlor-alkali platform producing chlorine, caustic soda, and downstream derivatives across Europe, North America and Asia. It mirrors UNID's chlor-alkali product mix and B2B industrial chemicals model.
• Tosoh Corporation: Tosoh is a Japanese chemical manufacturer that produces caustic potash (KOH) and related chlor-alkali chemicals via electrolysis, making it one of the closest direct competitors to UNID in the global KOH market. Both companies compete for semiconductor, fertilizer, and water treatment end markets.
• Westlake Corporation: Westlake operates integrated chlor-alkali and PVC facilities producing chlorine, caustic soda, hydrochloric acid and related derivatives. The chlorine/alkali co-product structure and downstream PVC exposure make it highly comparable to UNID's chlor-alkali value chain.
