FAQs About NAICS Code 331492
What metals are covered under NAICS 331492?
This code covers nonferrous metals except for copper and aluminum. Common examples include lead, zinc, nickel, precious metals (gold, silver, platinum), and other rare or specialty metals.
How does this industry contribute to sustainability?
By focusing on secondary smelting and refining, businesses under this code recycle scrap metal, reducing the need for primary mining and lowering environmental impact.
What types of businesses fall under this NAICS code?
Examples include lead smelting and refining facilities, zinc alloy production companies, nickel refining operations, and precious metal recovery businesses.
What is the typical business size for NAICS 331492?
To qualify as a small business under government standards, companies generally should have 850 or fewer employees.
Is copper or aluminum included in this NAICS code?
No. Copper and aluminum smelting and refining fall under separate NAICS codes.
Harnessing the power of recycling and metal processing, NAICS code 331492 is central to the manufacturing landscape involving secondary nonferrous metals — a critical link between raw resources and finished products that drives innovation and sustainability. Whether you’re a business owner, contractor, or industry professional, understanding the scope of NAICS 331492 is key to tapping into opportunities in manufacturing and recycling sectors.
