NAICS 334290
Overview
The North American Industry Classification System (NAICS) is the federal standard for classifying U.S. business establishments to support the collection, analysis, and publication of economic statistics. It is maintained by the Office of Management and Budget and revised about every five years; the current vintage is 2022, which superseded prior editions and replaced the SIC system in 1997. 1
Under the 2022 structure, NAICS 334290 covers establishments primarily engaged in manufacturing communications equipment not elsewhere classified. This category explicitly excludes telephone apparatus (classified in NAICS 334210) and radio/television broadcasting and wireless communications equipment (classified in NAICS 334220). 2
