Subsector 213

NAICS Subsector Code 213 – Support Activities for Mining

Definition of NAICS 3 Digit Subsector Code 213: Industries in the Support Activities for Mining subsector group establishments primarily providing support services, on a contract or fee basis, required for the mining and quarrying of minerals and for the extraction of oil and gas. Establishments performing exploration (except geophysical surveying and mapping) for minerals, on a contract or fee basis, are included in this subsector. Exploration includes traditional prospecting methods, such as taking core samples and making geological observations at prospective sites.

The activities performed on a contract or fee basis by establishments in the Support Activities for Mining subsector are also often performed in-house by mining operators. These activities include: taking core samples, making geological observations at prospective sites, excavating slush pits and cellars, and such oil and gas operations as spudding in, drilling in, redrilling, directional drilling, well surveying; running, cutting, and pulling casings, tubes and rods; cementing wells, shooting wells; perforating well casings; acidizing and chemically treating wells; and cleaning out, bailing, and swabbing wells.

Three Digit Subsector Breakdown for the North American Industry Classification System

NAICS codes are broken down by digit. The broadest description starts with the 2 digit sector codes. The 3 digit subsector codes are more specific, then the 4 digit industry group, 5 digit industry, and the most specific is the 6 digit NAICS code. If NAICS Subsector 213 does not describe the industry of the business in question, then select the largest applicable code below. From there, follow the progression of smaller digits to the larger digits in order to obtain the most specific 6 digit classification.
