NAICS 332510

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 about the U.S. economy. Created under the Office of Management and Budget and first implemented in 1997, NAICS was jointly developed by U.S. (ECPC), Canadian, and Mexican statistical agencies to provide comparable industry data across North America; the current Economic Census uses the 2022 vintage. ¹

NAICS 332510 — Hardware Manufacturing — covers establishments primarily engaged in manufacturing metal hardware such as metal hinges, metal handles, keys, and locks (except coin-operated or time locks). Illustrative examples on the official listing include metal safes and vaults, permanent metallic magnets, portable metal ladders, steel wool, metal pallets, and pipe hangers and supports. Cross-references exclude fasteners, nails from drawn wire, and certain architectural, structural, or coated products to other specific industries. ²
