NAICS 336370

Overview

The North American Industry Classification System (NAICS) is the production-oriented taxonomy the U.S. federal statistical system uses to classify business establishments for collecting, analyzing, and publishing economic data. Developed under the Office of Management and Budget (OMB) with Statistics Canada and Mexico’s INEGI, NAICS replaced SIC in 1997; the current structure supports a 2022 vintage. ¹

NAICS 336370 covers establishments primarily engaged in manufacturing motor vehicle stampings—such as fenders, tops, body parts, trim, and molding—within the broader Motor Vehicle Parts Manufacturing group. Federal economic programs and surveys publish industry statistics using this code under the 2022 NAICS framework. ²
