Hoang Son

What Hoang Son does

Hoàng Sơn (Công ty Cổ phần Hoàng Sơn Fly Ash And Cement) is a Vietnamese construction materials manufacturer founded in 2003 and headquartered in Ho Chi Minh City, with primary manufacturing at the Long Hậu Industrial Park in Long An Province. The company specializes in processing and classifying fly ash — a by-product of coal-fired thermal power plants — into supplementary cementitious materials used in cement and concrete production. Since May 2021, Hoàng Sơn has operated as a member of the European EP Power Minerals GmbH (EPPM) network under Czech EPH, gaining access to German processing technology, technical training, and international market reach.

The company's product portfolio spans four lines: processed fly ash (including a premium Ultra Fine Fly Ash grade with Blaine fineness of 8,000–12,000 cm²/g and 28-day pozzolanic activity index above 100% per ASTM C618), ground granulated blast furnace slag (GGBS), cement, and non-fired bricks at a capacity of 77 million pieces per year. Its fly ash processing plant uses German Christian Pfeiffer classification equipment at a nameplate capacity of 900,000 tons per year, supported by 12,000 tons of finished-product silo storage and a 120-meter pier capable of receiving 3,000-ton vessels. Differentiated downstream products include permeable interlocking bricks (developed with Japan's Eco System Inc.) and aesthetic paving stones (with Nam Khang Company).

Hoàng Sơn operates a B2B, transaction-fee commercial model serving enterprise customers that include Vietnam's major cement producers (Vicem, INSEE, Fico), the state-owned utility EVN as a fly ash supplier, premium real estate developers (Novaland, Vinhomes), and national infrastructure projects (including Hon Khoai Port in the Mekong Delta). Distribution combines direct enterprise sales with a proprietary specialized logistics fleet — SB-series tanker vessels licensed for operations within 12 nautical miles and closed-loop pumping systems — that supports marine and remote construction. The primary geographic focus is southern Vietnam with a documented export into Singapore beginning in September 2024.
