NAICS 113310

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying U.S. business establishments to support the collection, analysis, and publication of economic statistics. Developed under the Office of Management and Budget and first adopted in 1997, NAICS is jointly maintained with Canada and Mexico to enable cross-country comparability and is updated on a five-year cycle, most recently in 2022. ¹

NAICS 113310 covers establishments primarily engaged in logging operations—cutting timber; cutting and transporting timber; and producing wood chips in the field. The code is used by federal statistical programs and appears in cross-references that distinguish logging from related industries such as timber tract operations and sawmills. ²

What this NAICS covers

• Cutting standing timber for harvest (mechanized or manual felling). ²
• Integrated cutting and in-woods transport of timber to a landing or collection point. ²
• Producing wood chips in the field as part of logging operations. ²
• Skidding, yarding, or forwarding logs as part of the harvest workflow. ²
• Logging crews and camps performing timber harvesting activities. ²
• In-woods portable chipping associated with log harvesting. ²

• Includes operating portable chipper mills in the field under logging rather than sawmills. ²
• Excludes managing timber tracts for the purpose of selling standing timber; those activities fall under NAICS 113110. ⁴
• Excludes sawing logs into lumber and related mill activities, which are classified under NAICS 321113. ³
• Logging is classified in Sector 11 (Agriculture, Forestry, Fishing and Hunting), not in Manufacturing (Sectors 31–33). ²

Frequently asked questions

• What activities are included under NAICS 113310?

  • The official scope includes cutting timber; cutting and transporting timber; and producing wood chips in the field as part of logging operations. ²

• How does NAICS 113310 differ from NAICS 113110?

  • NAICS 113110 covers operating timber tracts to sell standing timber, while NAICS 113310 covers harvesting (cutting/transporting) and in-field chipping. ⁴

• Are sawmilling and planing included in NAICS 113310?

  • No. Sawmilling and related mill operations are covered by NAICS 321113. Logging may feed sawmills, but the manufacturing step is classified separately. ³

• Are in-woods chipping and portable chipper mills part of logging?

  • Yes. Producing wood chips in the field is explicitly included in logging activities. ²

• Which PSC codes commonly align to logging-type services?

  • Agencies often use natural resources management PSCs for forestry tasks, such as F014 Tree Thinning, F012 Survey Line Clearing, and F021 Site Preparation, depending on the statement of work. ⁵
