NAICS 111191

Overview

The North American Industry Classification System (NAICS) is the federal statistical standard used to categorize business establishments for the purpose of collecting, analyzing, and publishing data about the U.S. economy. Developed under the Office of Management and Budget in cooperation with Canada and Mexico, NAICS replaced the SIC system in 1997 to support consistent, cross‑country industry statistics. ¹
NAICS 111191 covers establishments growing a combination of oilseed(s) and grain(s) where no single oilseed (or family) or grain (or family) accounts for at least half of the operation’s agricultural production by value. The scope includes farms producing seeds and/or crops. If one crop family reaches at least 50 percent of production value, the establishment is classified to the corresponding single‑crop industry instead of 111191. ²

What this NAICS covers

• Combination farming of oilseed(s) and grain(s) when no single crop family reaches one‑half of production value. ²
• Growing oilseed and grain crops and/or producing oilseed and grain seeds on the farm. ²
• Annual‑cycle, open‑field crop operations characteristic of oilseeds and grains. ²
• Operations classified by the value of crops for market, not acreage or volume. ²
• Production activities completed at the “farm gate” (point of first sale or price determination). ²
• Reclassification to a single‑crop industry group when one crop family reaches at least one‑half of production value. ²

Frequently asked questions

• What distinguishes 111191 from single‑crop NAICS like 111110 or 111140?
  Classification hinges on the 50 percent rule. When one grain or oilseed family reaches at least half of the operation’s production value, the establishment is assigned to that specific single‑crop industry; otherwise, it is classified in 111191. ²

• Are seed‑production activities included in 111191?
  Yes. Census specifies establishments may produce oilseed(s) and grain(s) seeds and/or grow oilseed(s) and grain(s); both seed and crop production are in scope when the combination rule applies. ²

• Are postharvest cleaning or packing services part of 111191?
  No. When performed as services for others, these activities are classified under 115114 (Postharvest Crop Activities), while farm‑gate production remains in Subsector 111. ⁵

• Is 111191 eligible for the Women‑Owned Small Business (WOSB) Program?
  SBA’s eligible‑NAICS list includes 111191 as WOSB‑eligible. Program eligibility is governed by SBA; firms should confirm against the current SBA list before pursuing set‑asides. ⁶
