33141 - Nonferrous Metal (except Aluminum) Smelting and Refining

Introduction

If you're involved in the manufacturing sector or exploring opportunities in government contracting, NAICS code 33141 is a key classification to know. Focusing on Nonferrous Metal (except Aluminum) Smelting and Refining, this industry plays a critical role in processing essential metals like copper, lead, and zinc. Understanding this NAICS code can help businesses identify relevant market opportunities, comply with regulations, and connect with the right supply chains.

What is NAICS Code 33141?

NAICS code 33141 refers to establishments primarily engaged in smelting and refining nonferrous metals except aluminum from various inputs such as ore, pig, or scrap material. Nonferrous metals are metals that do not contain significant amounts of iron, making them resistant to rust and corrosion—qualities that are highly valued in many industrial applications.

Metals Covered under NAICS 33141:

• Copper
• Lead
• Zinc
• Other nonferrous metals (excluding aluminum)

These metals are foundational to numerous industries, including electronics, construction, automotive manufacturing, and more.

Sector and Typical Business Activities

This NAICS code falls under the Manufacturing sector, specifically focused on the chemical and metallurgy subsector related to metal processing.

Common Business Activities Include:

• Smelting raw ore to extract nonferrous metals
• Refining nonferrous metals to increase purity levels
• Processing scrap metal into reusable metal forms
• Operating smelting and refining plants dedicated to one or more nonferrous metals

Size Standards for NAICS 33141

To qualify as a small business under NAICS 33141 for government contracting purposes, the Small Business Administration (SBA) uses size standards based on the number of employees.

• Size Standard: 500 employees
  (This includes all employees in the business, including affiliates)

Understanding size standards is essential for small businesses seeking government contracts or assistance programs targeted at smaller enterprises.

Examples of Businesses Under NAICS 33141

• Copper Smelting and Refining Plants: Facilities that smelt and refine copper ore or scrap to produce pure copper products.
• Lead Smelting and Refining Facilities: Operations that extract and purify lead from ores or recycled materials.
• Zinc Smelting and Refining Operations: Companies specializing in processing zinc from raw or scrap materials.

Can businesses that recycle scrap metal be classified under NAICS 33141?

Yes, businesses primarily engaged in processing scrap nonferrous metals such as copper, lead, or zinc as part of smelting and refining are included in this classification.

Is NAICS 33141 relevant for government contracting?

Absolutely. Many federal agencies procure materials and services from businesses in this sector. Knowing your NAICS code and size standard helps when bidding on government contracts.

How can I find government contracting opportunities for NAICS 33141?

Platforms such as SAM.gov, the official U.S. government procurement site, list contracting opportunities searchable by NAICS codes including 33141.
