NAICS 332999

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. Developed under the Office of Management and Budget (OMB) and adopted in 1997 to replace SIC, NAICS was created jointly by the U.S. Economic Classification Policy Committee (ECPC), Statistics Canada, and Mexico’s INEGI; the current structure reflects the 2022 vintage. ²

NAICS 332999 covers U.S. establishments primarily engaged in manufacturing fabricated metal products not elsewhere classified within the fabricated metals subsector. The scope explicitly excludes items such as forgings and stampings, cutlery and handtools, architectural and structural metal products, boilers, tanks, shipping containers, hardware, spring and wire products, machine shop/turned products, fasteners, metal valves, ball and roller bearings, ammunition and small arms, fabricated pipe and fittings, industrial patterns, and enameled iron or metal sanitary ware. ¹
