NAICS 311511
Overview
The North American Industry Classification System (NAICS) is the common framework U.S. federal statistical programs use to classify business establishments for collecting, analyzing, and publishing data on the economy. Developed under the Office of Management and Budget and adopted in 1997 to replace the Standard Industrial Classification, NAICS is jointly maintained with Canada and Mexico; the current vintage is 2022. 1
NAICS 311511 (Fluid Milk Manufacturing) covers establishments primarily engaged in manufacturing processed milk products such as pasteurized milk or cream and sour cream, and in producing fluid milk dairy substitutes from soybeans and other nondairy substances. Cross-references delineate boundaries with other dairy product industries, ensuring activities like UHT/canned milk and frozen desserts are classified elsewhere. 2
