NAICS 333243

Overview

The North American Industry Classification System organizes businesses by their production processes to support federal statistical collection, analysis, and publication across the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS is maintained jointly by the United States, Canada, and Mexico; the current vintage used for Economic Census publications is 2022. ¹

Within NAICS 333 (Machinery Manufacturing), NAICS 333243 designates “Sawmill, Woodworking, and Paper Machinery Manufacturing.” Federal statistical programs use this 6-digit national industry to tabulate establishments primarily engaged in producing machinery for sawmilling and woodworking (non‑handheld) as well as machinery used to make or convert pulp, paper, and paperboard. Title and placement reflect the 2022 NAICS structure. ²
