NAICS 339910

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to compile, analyze, and publish statistics on the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997, NAICS was created jointly by the U.S. ECPC, Statistics Canada, and Mexico’s INEGI to ensure North American comparability; the current vintage is 2022. ¹

NAICS 339910 — Jewelry and Silverware Manufacturing — covers establishments primarily engaged in making jewelry, metal personal goods, precious‑metal cutlery and flatware, unassembled jewelry parts, and related lapidary work. It functions as an umbrella industry that includes U.S. industries 339911, 339912, 339913, and 339914. Federal statistical programs and economic censuses use this code to tabulate industry data. ²
