Granulated Blast Furnace Slag (GBFS)
Granulated blast furnace slag is produced by rapidly quenching molten slag from iron production with water, resulting in glassy, granular particles known as slag sand. It falls under HTS 2618.00.00.00 as granulated slag specifically from iron or steel manufacture, used primarily as a supplementary cementitious material in concrete production.
Steel Slag Sand
Granulated slag sand derived from the steelmaking process in electric arc furnaces, quenched to form fine granules. Classified under HTS 2618.00.00.00 due to its origin in steel manufacture and granular form suitable for road base or cement additives.
Iron Granulated Slag for Cement
Water-quenched granulated slag from pig iron production, appearing as sand-like granules ideal for blending into Portland cement. HTS 2618.00.00.00 covers this as slag sand directly from iron manufacture, prior to grinding.
