Slag, Dross, Scalings, and Other Waste from Iron or Steel Manufacture

Non-granulated slag, dross, scalings, and ferrous scale generated during iron and steel production are captured here across three US tariff lines: a general waste line (2619000000), ferrous scale specifically (2619003000), and a residual NESOI line (2619009000). These materials serve as secondary raw material inputs — ferrous scale, for example, is recycled back into steelmaking as an iron-bearing charge — and their trade flows closely mirror steel industry activity. Canada and Mexico are the top suppliers, reflecting integrated North American steel supply chains, with Japan and India also among leading sources.
