NAICS 423430

Overview

The North American Industry Classification System (NAICS) is the federal standard for categorizing business establishments to support the collection, analysis, and publication of U.S. economic statistics. Developed by the U.S. Office of Management and Budget in collaboration with Canada and Mexico, NAICS replaced the SIC system in 1997 and has been updated on a five-year cycle through the 2022 revision to maintain cross-national comparability in business statistics. ¹
U.S. Industry 423430 is titled “Computer and Computer Peripheral Equipment and Software Merchant Wholesalers.” Official materials place this industry in Sector 42 (Wholesale Trade) and describe it as covering the wholesaling of computers, computer peripheral equipment, loaded computer boards, and/or computer software. Federal statistical programs and cross-references use this code to distinguish wholesale distributors of IT hardware and packaged software from retail outlets and IT services firms. ²

What this NAICS covers

• Merchant wholesale distribution of computers (e.g., desktops, laptops, servers). ²
• Merchant wholesale distribution of computer peripheral equipment such as monitors, printers, storage devices, and input/output hardware. ²
• Wholesaling of loaded computer boards and similar assembled PC boards. ²
• Wholesaling of packaged/commercial computer software (licenses) as a product. ²
• Wholesale channels serving resellers and institutional end users within the same industry classification. ⁴
• Incidental supporting services provided with wholesaling, such as customized assembly of personal computers. ³

Frequently asked questions

• What kinds of products are included under NAICS 423430?
  Computers, computer peripheral equipment (e.g., monitors, printers, storage), loaded computer boards, and packaged computer software distributed through wholesale channels are included. The emphasis is wholesaling rather than retailing or services. ²

• Does custom PC assembly move an establishment out of NAICS 423430?
  No. Official cross-references indicate that wholesaling computer hardware or software with supporting services like customized assembly remains in NAICS 423430, whereas systems design/consulting falls under NAICS 541512. ³

• How is NAICS 423430 different from NAICS 423690?
  NAICS 423430 covers computers, peripherals, and packaged software. NAICS 423690 covers other electronic parts and equipment. Historical cross-references explicitly separate computer/peripheral wholesaling from other electronic components. ⁴
