NAICS 337920

Overview

The North American Industry Classification System (NAICS) organizes U.S. business establishments for statistical purposes. First adopted in 1997 to replace SIC, NAICS was developed by the U.S. Economic Classification Policy Committee in cooperation with Statistics Canada and Mexico’s INEGI to ensure comparable business statistics across North America; the current classification vintage is 2022. ¹
