NAICS 332993

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments so agencies can collect, analyze, and publish statistics on the U.S. economy. Developed under the Office of Management and Budget with the Economic Classification Policy Committee alongside Statistics Canada and Mexico’s INEGI, NAICS was adopted in 1997 to replace SIC and to improve cross-country comparability; the current vintage is 2022. ²
U.S. Industry NAICS 332993 covers establishments primarily engaged in manufacturing ammunition other than small arms. Examples include bombs, depth charges, non-guided rockets, grenades, mines, and torpedoes. Federal statistical programs and contract reporting use this classification to delineate activity and publish industry data. ¹
