NAICS 334111

Overview

The North American Industry Classification System (NAICS) is the framework federal statistical programs use to categorize business establishments for consistent collection, analysis, and publication of data on the U.S. economy. Developed by the Office of Management and Budget’s Economic Classification Policy Committee with Statistics Canada and Mexico’s INEGI, NAICS replaced the SIC system in 1997 and is revised every five years; the current vintage is 2022. ²

NAICS 334111 — Electronic Computer Manufacturing — covers establishments primarily engaged in manufacturing and/or assembling electronic computers, including mainframes, personal computers, workstations, laptops, and computer servers. Computers may be analog, digital, or hybrid; assembly/integration of processors, memory, storage, and I/O into a user-programmable end product is in-scope. ¹

What this NAICS covers

• Manufacturing of personal computers and laptops intended as user-programmable electronic computers. ¹
• Production of enterprise computer servers and mainframes. ¹
• Manufacturing of workstations and similar user-programmable computer systems. ¹
• Assembly/integration of processors, coprocessors, memory, storage, and I/O devices into finished computers. ¹
• Manufacturing of electronic computers that are analog, digital, or hybrid. ¹
• In-scope computer manufacturing regardless of operating system (e.g., Windows, Linux, UNIX). ¹

Key inclusions and exclusions (per NAICS manual)

• Includes manufacturing/assembly of electronic computers (e.g., mainframes, PCs, laptops, servers) as the finished, user-programmable product. ¹
• Excludes telecom switches and network equipment; those are classified in 334210. ¹
• Excludes blank magnetic/optical media, which fall under 334613. ¹
• Excludes internal loaded PCB devices (e.g., sound/video/controller/network cards), modems, and semiconductor storage devices; these are under 33441. ¹
• Excludes casings, stampings, cable sets, and switches manufactured as parts; these are classified by the associated production process outside 334111. ¹

Where it appears in federal data

• The 2022 Economic Census publishes detailed manufacturing statistics for NAICS Sector 31–33, including industries within 334111 scope. ⁵
• The Census Bureau’s BDS High Tech experimental series designates the broader 3341 industry group as “High Tech,” reflecting high STEM occupation intensity; 334111 is part of this group. ⁶

Frequently asked questions

• What products fall under NAICS 334111?

  • Electronic computers such as mainframes, servers, workstations, desktops, and laptops. Coverage includes analog, digital, and hybrid computers, and extends to assembly/integration of components into user-programmable systems. ¹

• How is 334111 different from 334112 or 334119?

  • 334111 covers finished electronic computers. 334112 covers storage devices (e.g., HDD, tape), while 334119 covers other peripherals (e.g., monitors, input/output devices) — not the computers themselves. ¹

• Does assembly/integration without fabricating components qualify under 334111?

  • Yes. The industry explicitly includes assembly/integration of processors, memory, storage, and I/O devices into a user-programmable final product classified as an electronic computer. ¹

• Which PSC codes commonly align to federal buys of computers under 334111?

  • Hardware purchases often map to PSC 7B22 (Compute: Servers) and 7E20 (End User hardware/software), with 7B20 used for high-performance computing. Refer to the current PSC Manual for definitions. ⁴

• Did the 2022 NAICS update change the definition of 334111?

  • Not specified by official sources. The Census implementation notes 2022 revisions across sectors but does not detail a change specific to 334111 in its summary resources. ³
