33131 - Alumina and Aluminum Production and Processing
The North American Industry Classification System (NAICS) code 33131 is vital for businesses and contractors operating within the aluminum sector. Whether you’re a manufacturer, supplier, or government contractor, knowing the ins and outs of NAICS 33131 - Alumina and Aluminum Production and Processing can help you identify opportunities, meet compliance, and grow your presence in the manufacturing industry.
What is NAICS Code 33131?
NAICS code 33131 encompasses industries primarily engaged in the production of alumina and aluminum. This includes both primary aluminum production — where raw materials are transformed into aluminum metal — and aluminum processing activities such as rolling, drawing, and extruding. These processes turn basic raw materials into usable aluminum components that support a wide range of manufacturing sectors, including automotive, aerospace, construction, and packaging.
Sector Overview: Manufacturing
NAICS 33131 falls under the broader sector of Manufacturing (NAICS Sector 31-33). This sector is integral to the U.S. economy, involved in converting raw materials into finished goods.
Typical Business Activities Under NAICS 33131:
- Primary Aluminum Production Plants: Facilities that extract aluminum from bauxite ore and refine it into alumina and primary aluminum.
- Aluminum Rolling Mills: Establishments that roll aluminum into sheets and coils for industrial use.
- Aluminum Extrusion and Drawing Facilities: Plants that process aluminum into rods, bars, tubes, and other shapes through extrusion or drawing.
Size Standards for NAICS 33131 Eligibility
For government contracting and small business classification, the Small Business Administration (SBA) typically uses industry-specific size standards based on employee count or annual receipts.
- Size Standard for NAICS 33131:
- 1,250 employees (for size standard purposes in government contracting)
This means businesses with 1,250 or fewer employees are generally considered small for this code and may qualify for small business programs.
Examples of Businesses under NAICS 33131
- Aluminum Manufacturing Companies: Businesses producing primary aluminum or alumina.
- Rolling Mills Operators: Companies specializing in the production of aluminum sheets and coils.
- Extrusion and Drawing Firms: Organizations focused on aluminum profile manufacturing for various industries.
