NAICS 334511
Overview
The North American Industry Classification System (NAICS) is the governmentwide standard for classifying U.S. business establishments to support statistical collection, analysis, and publication. Created under the Office of Management and Budget and adopted in 1997 to replace the SIC, NAICS was jointly developed with Statistics Canada and Mexico’s INEGI; the current vintage is 2022. 1
NAICS 334511 covers establishments primarily engaged in manufacturing search, detection, navigation, guidance, aeronautical, and nautical systems and instruments. Examples include aircraft instruments (except engine instruments), flight recorders, navigational instruments and systems, radar systems and equipment, and sonar systems and equipment. Global Positioning System (GPS) equipment is classified under NAICS 334220; aircraft engine instruments and meteorological systems/equipment fall under NAICS 334519. 2
