NAICS 111140

Overview

The North American Industry Classification System (NAICS) is the governmentwide framework U.S. statistical agencies use to categorize establishments for economic data collection, analysis, and publication. Developed under the Office of Management and Budget with Canada and Mexico, NAICS replaced SIC in 1997; the system is updated on a five-year cycle, with the current vintage designated 2022. ¹
U.S. NAICS industry 111140 covers establishments primarily engaged in growing wheat and/or producing wheat seed. Within Sector 11, oilseed and grain crops are annual and typically field-grown; classification is based on the commodity that accounts for at least one-half of agricultural production value. Cross-references direct combination grain–oilseed operations to 111191. ²

What this NAICS covers

• Wheat cultivation for grain, including field operations integral to the farm’s own wheat production. ²
• Production of wheat seed for planting. ²
• Oilseed and grain farming context: annual-cycle crops, typically grown in open fields. ²
• Farm output defined at the “farm gate” (point of first sale or price determination). ²
• Establishments where wheat accounts for at least one-half of the value of agricultural production. ²
• Wheat grown alone rather than as part of a mixed oilseed–grain operation. ²
