111940

Analysis

NAICS 111940 is the 2022 national industry for hay farming, part of 11194 (Hay Farming). Census lists 5 example activities under it in the official index.

Its index entries, the activities Census uses to assign businesses to this code, include alfalfa hay farming, clover hay farming, grass hay farming and hay farming (e.g., alfalfa hay, clover hay, grass hay), among 5 in all.

Its goods appear in 4 statistical lines of the US tariff schedule, mostly under headings 1214 (rutabagas (swedes), mangolds, fodder roots, hay, alfalfa…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.

For example, growing grain hay are classified in 1111 (Oilseed and Grain Farming) instead.

Census lists 2 related activities that belong elsewhere, most often in 1111 and 111998. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.

County Business Patterns does not cover crop and animal production, so there is no establishment count for it; farms are counted by the Census of Agriculture instead.
