NAICS 326291

Overview

The North American Industry Classification System (NAICS) is the framework U.S. Federal statistical agencies use to categorize business establishments for the collection, analysis, and publication of economic data. Developed under the Office of Management and Budget with Statistics Canada and Mexico’s INEGI, the current Economic Census is published on the 2022 NAICS vintage. ¹
NAICS 326291 is a U.S. industry within Subsector 326 (Plastics and Rubber Products) covering establishments primarily engaged in molding, extruding, or lathe‑cutting rubber to make goods (except tubing) for mechanical applications—typically parts used in motor vehicles, machinery, and equipment. Cross‑references direct rubber tubing and rubber products for mechanical use produced by other processes to NAICS 326299. ²
