NAICS 115310

Overview

The North American Industry Classification System (NAICS) is the federal statistical standard for classifying business establishments to produce and share economic statistics on the U.S. economy. Developed under the auspices of the Office of Management and Budget and adopted in 1997 to replace the SIC, NAICS was created jointly by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s Instituto Nacional de Estadística y Geografía; the current revision in use is the 2022 vintage. ¹

NAICS 115310 — Support Activities for Forestry — covers establishments primarily engaged in specialized support services tied to timber production, wood technology, forestry economics and marketing, and forest protection. Examples include timber estimation, forest firefighting, forest pest control, and consulting on wood attributes and reforestation. Public administration and conservation of forest lands is excluded and classified under NAICS 924120. ²
