Which code does this activity belong in?
NAICS 331491 covers establishments that shape nonferrous metals (except copper and aluminum) through rolling, drawing, or extruding operations, whether working from purchased metal or from scrap material in integrated facilities. The distinction from NAICS 331492 is that 331491 produces finished shapes such as bars, plates, sheets, strips, and tubes, whereas 331492 produces primary forms like ingots, billets, and slugs through smelting or refining processes before any shaping occurs.
