NAICS 111199

Overview

The North American Industry Classification System (NAICS) is the federal standard for categorizing business establishments so statistical agencies can compile, analyze, and publish data about the U.S. economy. Developed under OMB with Canada and Mexico, NAICS replaced SIC in 1997 and is updated on a five-year cycle; the current vintage is 2022.¹
NAICS 111199 covers establishments primarily engaged in growing grains and/or producing grain seeds other than wheat, corn, and rice. It clarifies boundaries with adjacent industries, such as wheat, corn, rice, and oilseed–grain combination farming, via formal cross-references used for statistical classification and data reporting.²

Classification boundaries and cross-references

• Wheat is classified under NAICS 111140; wheat–oilseed combos without a predominant crop fall under NAICS 111191, not NAICS 111199.²
• Corn (except sweet corn) is classified under NAICS 111150; sweet corn is classified under NAICS 111219, not NAICS 111199.²
• Rice (except wild rice) is classified under NAICS 111160; wild rice is explicitly included in NAICS 111199.²
• Establishments growing a combination of grains and oilseeds with no single crop family accounting for at least half of output are classified in NAICS 111191, not NAICS 111199.²

Frequently asked questions

• What activities fall under NAICS 111199?
  Establishments that grow grains other than wheat, corn, and rice, and those producing seeds for such grains. Illustrative examples include barley, oats, rye, sorghum (milo), and wild rice.²

• How does NAICS 111199 differ from wheat, corn, and rice farming codes?
  Wheat, corn (except sweet corn), and rice (except wild rice) are classified in NAICS 111140, 111150, and 111160, respectively. NAICS 111199 covers other grains and their seeds.²

• Are wild rice farms included in NAICS 111199?
  Yes. Wild rice is specifically listed under NAICS 111199, while cultivated rice is classified under NAICS 111160.²

• What if a farm grows both grains and oilseeds without a dominant crop?
  Those operations are classified under NAICS 111191 (Oilseed and Grain Combination Farming), not NAICS 111199.²

• When was the 2022 NAICS implemented and how often is NAICS updated?
  NAICS is revised every five years; agencies are transitioning programs to the 2022 vintage, with most Census programs adopting by the end of 2027.¹
