3311 - Iron and Steel Mills and Ferroalloy Manufacturing

When it comes to the backbone of modern infrastructure and countless industrial applications, NAICS code 3311 stands tall. This crucial classification encompasses the manufacturing activities related to iron, steel, and ferroalloy production—the very materials that fuel construction, transportation, and manufacturing worldwide. Understanding NAICS 3311 is key for businesses in the manufacturing sector, government contractors, and industry analysts aiming to navigate and excel in these markets.

What Is NAICS Code 3311?

NAICS Code 3311: Iron and Steel Mills and Ferroalloy Manufacturing covers establishments primarily engaged in the production of iron, steel, and ferroalloys by smelting iron ore, scrap metal, or other raw materials. This industrial sector includes integrated steel mills, which transform raw iron into steel products, as well as steel foundries that cast and shape steel for various applications. Additionally, ferroalloy manufacturing plants produce essential alloys used to improve steel's properties during production.

Sector and Business Activities Under NAICS 3311

• Sector: Manufacturing
• Primary Activities:
  • Smelting iron ore and scrap to produce iron and steel.
  • Producing ferroalloys that modify the properties of steel.
  • Operating integrated steel mills producing steel sheets, coils, bars, and rods.
  • Steel foundries casting steel products used in automotive, construction, and machinery industries.

Examples of Typical Business Types:

• Integrated Steel Mills: Facilities producing flat-rolled steel sheets and coils used in automotive manufacturing and construction.
• Ferroalloy Manufacturing Plants: Plants creating ferrochrome, ferromanganese, and other alloys that enhance steel strength and durability.
• Steel Foundries: Businesses casting custom steel parts for industrial machinery and infrastructure projects.

Size Standards and Eligibility

For businesses interested in government contracts or qualifying for small business programs, the Small Business Administration (SBA) has set size standards within this NAICS code. These standards are typically based on the number of employees.

NAICS Code	Description	SBA Size Standard
3311	Iron and Steel Mills and Ferroalloy Manufacturing	1,250 employees (standard size standard for small business eligibility)

This means companies operating under NAICS 3311 with 1,250 or fewer employees are generally considered small businesses for federal contracting and assistance programs.

Frequently Asked Questions (FAQs)

What products are made by industries in NAICS 3311?

Typical products include steel sheets, coils, bars, rods, custom cast steel parts, and ferroalloys such as ferrochrome and ferromanganese used in steelmaking.

Who uses the products of NAICS 3311 industries?

Major consumers are construction companies, automotive manufacturers, heavy machinery producers, and other industrial sectors requiring strong, durable steel components.

Can a small business qualify under NAICS 3311 for government contracts?

Yes. Businesses with 1,250 or fewer employees operating within this sector can be considered small businesses for contracting purposes.

What is a ferroalloy and why is it important?

A ferroalloy is an alloy of iron combined with one or more other elements like manganese or chromium, added during steelmaking to improve the final product's strength, durability, or corrosion resistance.

Are recycling operations included in NAICS 3311?

While scrap metal is used as a raw material, scrap processing and recycling themselves fall under different NAICS codes. NAICS 3311 focuses on the smelting and manufacturing stages.
