NAICS 332323

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to enable consistent collection, analysis, and publication of U.S. economic statistics. Developed under the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS is jointly maintained with Canada and Mexico and is currently in its 2022 vintage. ¹

NAICS 332323 covers establishments primarily engaged in manufacturing ornamental and architectural metal work, including staircases, metal open steel flooring, fire escapes, railings, and scaffolding; prefabricated metal buildings are classified elsewhere (see related codes below). Agencies use this code to categorize metal architectural product manufacturers in economic statistics and as a reference point in acquisition planning and market research. ²

How agencies use this code

NAICS is designed for statistical purposes, but it is frequently used across government for administrative, regulatory, and contracting activities (e.g., market research, set-aside eligibility checks, and reporting). As such, NAICS 332323 can appear in solicitations or past performance queries even though award reporting ultimately relies on PSC for “what was bought.” ³

Frequently asked questions

• What products are included in NAICS 332323?

  It includes ornamental and architectural metal work such as metal staircases, open steel flooring, fire escapes, railings, and scaffolding. Prefabricated metal buildings are excluded and classified in a different NAICS industry. ²

• How is NAICS 332323 different from 332321 or 332322?

  NAICS 332323 focuses on ornamental/architectural metal work (e.g., stairs, railings). NAICS 332321 covers metal windows and doors, while NAICS 332322 covers sheet metal work; each has distinct manufacturing scopes per Census cross-references. ²

• Which PSCs are commonly associated with items from NAICS 332323?

  PSC selection depends on the specific end item (e.g., scaffolding vs. fencing). Use the current Product and Service Code Manual to identify the correct PSC that matches the product described in the requirement. ⁴

• What is the small business size standard for NAICS 332323?

  SBA sets size standards by NAICS. Contracting personnel and offerors should consult SBA’s Table of Small Business Size Standards or the Size Standards Tool to determine the current threshold for this code. ⁵
