212323 - Kaolin, Clay, and Ceramic and Refractory Minerals Mining

Introduction

In the vast landscape of the mining industry, NAICS Code 212323 holds a crucial role by defining the economic activities related to the mining of kaolin, clay, and ceramic and refractory minerals. These essential raw materials underpin a wide array of industrial processes and products, including ceramics, refractories, paper, paint, and more. Understanding this NAICS code is vital for businesses, contractors, and professionals involved in the mining and extraction sector, as well as those looking to engage with this industry in a government or commercial capacity.

What Is NAICS Code 212323?

NAICS 212323 is designated for establishments primarily engaged in the mining and extraction of:

• Kaolin
• Clay
• Ceramic minerals
• Refractory minerals

These naturally occurring minerals serve as foundational inputs for manufacturing industries producing ceramics, bricks, refractories (materials resistant to heat and used in furnaces and kilns), and other industrial uses. This code ensures accurate classification of businesses involved in extracting these minerals from deposits, quarries, and mines.

Sector Overview: Mining, Quarrying, and Oil and Gas Extraction

NAICS 212323 falls under the broader sector of Mining, Quarrying, and Oil and Gas Extraction. This sector is characterized by the extraction of naturally occurring mineral solids, liquid minerals, and gases. Firms operating under NAICS 212323 specialize in:

• Kaolin mining operations: Extraction of kaolin, a fine, white clay used in paper, paint, rubber, and ceramics.
• Clay extraction businesses: Mining clay deposits used in pottery, construction, and industrial applications.
• Refractory mineral mining companies: Harvesting minerals that withstand high temperatures, crucial for steel production, glass manufacturing, and cement industries.

Eligibility and Size Standards

For government contracting and classification purposes, the size standard for NAICS code 212323 is typically up to 650 employees. Businesses with a workforce equal to or less than this threshold are considered small and eligible for certain small business programs and federal contracts.

Examples of Businesses Under NAICS 212323

Organizations classified under this code typically include:

• Kaolin Mines Inc.: Specializes in the extraction and processing of high-purity kaolin for industrial use.
• ClayWorks Mining LLC: A medium-sized operation focused on clay deposits for ceramic and construction applications.
• Refracta Minerals Co.: Combines mining of refractory minerals with custom processing to serve steel and glass manufacturers.

These firms represent the diverse nature and industrial significance of companies working under NAICS 212323.

Frequently Asked Questions (FAQs)

1. What industries use materials mined under NAICS 212323?

Materials mined under this code are used in ceramics, refractories for steel and glass production, paper manufacturing, rubber processing, paint formulation, and various industrial applications requiring heat-resistant materials.

2. How is NAICS 212323 different from other mining codes?

NAICS 212323 specifically covers kaolin, clay, ceramic, and refractory minerals, which are distinct from metallic ores, coal, or oil and gas mining covered under other NAICS codes.

3. Can small businesses qualify under NAICS 212323 for government contracting?

Yes. Businesses with 650 or fewer employees are classified as small under this code and can participate in small business set-asides and other contracting programs.

4. What are refractory minerals?

Refractory minerals are materials that can withstand extremely high temperatures without melting or breaking down, often used to line furnaces and kilns in heavy industries.

5. How does the mining process differ for kaolin versus clay?

While both involve extraction from the earth, kaolin mining typically requires refined processing to produce the pure, fine clay used in specialized applications, whereas clay mining can be more diverse depending on the end product.
