331492 Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum)

This U.S. industry comprises establishments primarily engaged in (1) alloying purchased nonferrous metals and/or (2) recovering nonferrous metals from scrap. Establishments in this industry make primary forms (e.g., bar, billet, bloom, cake, ingot, slab, slug, wire) using smelting or refining processes.

Cross-References. Establishments primarily engaged in--
  • Recovering aluminum and aluminum alloys from scrap and/or alloying purchased aluminum--are classified in U.S. Industry 331314, Secondary Smelting and Alloying of Aluminum;
  • Sorting, breaking up, and wholesaling scrap metal without also smelting or refining--are classified in Industry 423930, Recyclable Material Merchant Wholesalers;
  • Recovering nonferrous metals from scrap and rolling, drawing, or extruding shapes in integrated facilities--are classified in U.S. Industry 331491, Nonferrous Metal (except Copper and Aluminum) Rolling, Drawing, and Extruding;
  • Operating facilities where commingled recyclable materials, such as paper, plastics, used beverage cans, and metals, are sorted into distinct categories without also smelting or refining--are classified in Industry 562920, Materials Recovery Facilities; and
  • Recovering copper and copper alloys from scrap and making primary forms, and/or alloying purchased copper--are classified in Industry 331420, Copper Rolling, Drawing, Extruding, and Alloying.
