NAICS 336350

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to support the collection, analysis, and publication of statistics on the U.S. economy. Developed under the Office of Management and Budget with Canada and Mexico, NAICS replaced the Standard Industrial Classification in 1997 and the latest structure used for economic statistics is the 2022 vintage. ¹

Under the 2022 NAICS structure, 336350 covers establishments primarily engaged in manufacturing and/or rebuilding motor vehicle transmissions and power train parts. These definitions guide how the Census Bureau and other statistical programs tabulate data, with programs transitioning to full 2022 NAICS adoption through 2027. ³
