NAICS 339940

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments to support the collection, analysis, and publication of U.S. economic statistics. Developed under the Office of Management and Budget (OMB) and adopted in 1997 to replace SIC, NAICS is jointly maintained with Statistics Canada and Mexico’s INEGI and is updated on a five-year cycle, with the current vintage being 2022. ¹
NAICS 339940 Office Supplies (except Paper) Manufacturing covers establishments primarily engaged in making non-paper office supplies such as pens, pencils, felt‑tip markers, crayons, chalk, pencil sharpeners, staplers, hand‑operated stamps, stencils, modeling clay, and inked ribbons. Agencies and vendors use this industry code to classify production‑oriented manufacturing of these items; paper office products are classified elsewhere. The detailed industry description and cross‑references define inclusions and exclusions for consistent classification across federal data and procurement. ²
