NAICS 337127

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to facilitate the collection, analysis, and publication of statistics on the U.S. economy. Developed under the Office of Management and Budget (OMB) and adopted in 1997 to replace SIC, NAICS was created jointly with Statistics Canada and Mexico’s INEGI to support cross‑country comparability. NAICS is revised every 5 years; the current classification vintage used for most economic statistics is 2022 ¹.

NAICS 337127 covers establishments primarily engaged in manufacturing institutional‑type furniture—such as library, school, theater, and church furniture—produced on a stock or custom basis, and sold assembled or as knockdown units. Federal statistical programs use this code to classify and tabulate activity for institutional furniture manufacturing within the Manufacturing sector (31‑33) ².
