NAICS 112210

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments so agencies can collect, analyze, and publish statistics about the U.S. economy. Developed under the Office of Management and Budget (OMB) and adopted in 1997 to replace SIC, it is maintained jointly with Statistics Canada and Mexico’s INEGI to keep data comparable across North America. ¹

The current classification vintage is 2022; Census programs are transitioning to publish on the 2022 NAICS basis following the agency’s implementation timeline. ³

NAICS 112210 (Hog and Pig Farming) covers establishments primarily engaged in raising hogs and pigs. Activities may include breeding and farrowing, and the raising of weanling pigs, feeder pigs, or market-size hogs. This code defines primary production only; downstream slaughtering or processing are classified outside this industry. ²

What this NAICS covers

• Swine breeding operations and farrowing units. ²
• Raising weanling pigs for subsequent grow-out. ²
• Production of feeder pigs sold to finishing operations. ²
• Finishing/grow-out of hogs to market weight. ²
• Integrated farrow‑to‑finish hog production. ²
• Contract or company-owned farms whose primary activity is raising hogs/pigs. ²

Scope notes and exclusions

• Stockyard operations for transportation (not buying/selling) are excluded; classify under NAICS 488999. ²
• Slaughtering and meat processing are excluded; classify under NAICS 311611 or related manufacturing industries. ⁶
• Breeding, boarding, and other support services to livestock producers (when not primarily raising animals) fall under NAICS 115210. ²

Data coverage and reporting

• The 2022 Economic Census does not cover NAICS 112 industries (Animal Production and Aquaculture); it publishes detailed industry statistics using the 2022 NAICS vintage for in-scope sectors, with exceptions noted by program. ³
• “Codes Not Covered” for the 2022 Economic Census indicates 111 and 112 are excluded; support activities NAICS 1151 and NAICS 1152 are the exceptions within Sector 11. Not specified by official sources. ⁴

Frequently asked questions

• What activities are included in NAICS 112210?
  Establishments primarily raise hogs and pigs, including breeding and farrowing, as well as the production of weanling pigs, feeder pigs, and market hogs. The scope is limited to live-animal production; buying, selling, slaughtering, or processing activities are outside this industry’s boundaries. ²

• Are slaughtering or pork processing covered by NAICS 112210?
  No. Slaughtering and processing are in Manufacturing under NAICS 311611 and related NAICS 3116 industries. NAICS 112210 covers the production of live hogs and pigs only, not downstream processing. ⁶

• Is NAICS 112210 included in the 2022 Economic Census tabulations?
  No. Sector 11’s agricultural production industries (including 111 and 112) are not covered by the 2022 Economic Census; certain support activities are included instead. Agencies are moving to 2022 NAICS for reporting according to the Census implementation schedule. ⁴

• Which PSC codes most often align with buys related to this activity?
  Purchases of live swine typically use PSC 8810 (Live Animals, Raised for Food). For meat and related food products, agencies generally use PSC 8905 (Meat, Poultry, and Fish). Selection depends on whether the requirement is for live animals versus processed products. ⁵

• Are stockyards part of NAICS 112210?
  No. Operating stockyards strictly for transportation (without buying, selling, or auctioning) is classified under NAICS 488999. NAICS 112210 applies when the primary activity is raising hogs and pigs. ²
