Official definition
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.

Which code does this activity belong in?
Secondary smelting, refining, and alloying of nonferrous metals (except copper and aluminum) comprises establishments that recover these metals from scrap or alloy purchased metals using smelting or refining processes to produce primary forms such as ingots, billets, and slugs. The key distinction from rolling, drawing, and extruding operations is the production stage: this code covers the initial transformation into primary forms through smelting and refining, while NAICS 331491 covers the subsequent shaping of metals into finished forms like plate, sheet, and strip through rolling, drawing, or extruding.
