    2131 - Support Activities for Mining

    The mining industry is a backbone of natural resource extraction, and behind every successful mining operation lies an array of specialized services that keep the process efficient and productive. One critical classification that captures these services is NAICS code 2131 - Support Activities for Mining. Whether you’re a business owner, government contractor, or industry professional, understanding this NAICS code is essential for identifying market opportunities and regulatory compliance within the mining sector.


    What is NAICS Code 2131?

    NAICS code 2131 is designated for establishments primarily engaged in performing support activities on a contract or fee basis for mining and quarrying operations. This category covers a wide range of services essential to mineral extraction but excludes companies that directly extract minerals themselves.

    Key activities include:

    • Mineral exploration services
    • Drilling and boring services
    • Geophysical surveying
    • Mine site preparation
    • Other contractual activities assisting with mining extraction

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

    NAICS 2131 falls under the broader Mining, Quarrying, and Oil and Gas Extraction Sector (NAICS 21). This sector is pivotal in supplying raw materials that fuel various industries and manufacturing processes.

    Typical Business Activities under 2131

    • Exploration Services: Geological and geophysical studies to locate mineral deposits.
    • Drilling Contractors: Contract drilling for oil, gas, coal, metals, and other minerals.
    • Mine Site Preparation Services: Clearing, excavation, and infrastructure support on mining sites.

    Size Standards for NAICS Code 2131

    To qualify for small business status under this NAICS code (important for federal contracting and SBA programs), businesses must meet the following size standards as defined by revenue or employee count:

    NAICS Code Size Standard (Revenue or Employees) Description
