NAICS 325613

Overview

The North American Industry Classification System (NAICS) is the framework federal statistical agencies use to categorize business establishments so they can collect, analyze, and publish data on the U.S. economy. NAICS was developed under the Office of Management and Budget, adopted in 1997 to replace SIC, and jointly designed by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s Instituto Nacional de Estadística y Geografía; the current classification vintage is 2022. ¹

NAICS 325613 covers U.S. establishments primarily engaged in manufacturing bulk surface-active agents used as wetting agents, emulsifiers, and penetrants, and/or in producing textile and leather finishing agents that reduce surface tension or accelerate drying. Federal programs and the Economic Census use this code to classify and tabulate industry statistics at the 6-digit level. ²
