SIC and NAICS Codes for Thermography

SIC and NAICS codes are numerical codes used to categorize a wide variety of products and services. Knowing the proper codes can be helpful in preparing contract documents, searching databases, or completing forms and reports where such numbers are required.

Standard Industrial Classification (SIC ) are numerical codes designed by the U.S. Government in order to create uniform descriptions of business establishments. SIC codes can be used to search databases and/or to identify companies that produce specific products or services.

The SIC code for Infrared Inspection Services is: 8734-15. This is a subset of the heading, Testing Laboratories.

Other SIC codes that may be of interest to thermographers are as follows:

Electrical Power Systems – Maintenance: 7389-43

Roofing Service Consultants: 8748-09

In 1997, the North American Industry Classification System (NAICS) replaced the SIC system. The NAICS was developed jointly by the U.S., Canada, and Mexico to provide new comparability in statistics about business activity across North America.

In the 2002 version of the NAICS, Infrared Inspection Services are classified under code 541380, Testing Laboratories. As with SIC codes, a company’s classification may include other categories depending upon a company’s core business and/or future changes to existing NAICS codes.
