NAICS 334112

Overview

The North American Industry Classification System (NAICS) is the governmentwide standard for organizing establishments by production process so agencies can collect, analyze, and publish economic statistics. Developed under the Office of Management and Budget with counterparts in Canada and Mexico, NAICS replaced the SIC in 1997 and is updated on a five-year cycle; the current vintage is 2022. ¹
U.S. industry code 334112 covers firms primarily engaged in manufacturing computer storage devices that record and retrieve data on phase-change, magnetic, optical, or magneto-optical media. Illustrative products include CD-ROM drives, floppy disk drives, hard disk drives, and tape storage/backup units. Federal datasets, procurement market research, and size standards often reference this code to delineate hardware producers distinct from semiconductor memory, blank media, or printed circuit assembly manufacturing. ²

• Excluded: drive controller cards (internal or external to the storage device), classified under 334418. ²
• Excluded: blank magnetic and optical recording media, classified under 334613. ²
• Excluded: other parts such as casings, stampings, cable sets, and switches—classified elsewhere based on production process. ²

Frequently asked questions

• What products fall under 334112?
  Establishments manufacture computer storage devices that read/write to physical media, including hard disk drives, optical drives (e.g., CD-ROM), tape backup units, and floppy drives. The scope covers complete storage devices, not component chips, blank media, or controller cards. ²

• Are solid-state memory devices (e.g., memory chips) included in 334112?
  No. Semiconductor storage devices such as memory chips are classified in 334413. NAICS 334112 covers storage devices that operate on magnetic, optical, magneto-optical, or phase-change media. ²

• How does 334112 differ from 334119?
  334119 covers other computer peripheral equipment (except storage devices and terminals). Storage device manufacturing is specifically assigned to 334112. ²

• Which PSCs are commonly used for storage hardware buys aligned to 334112?
  The PSC Manual includes category 7K20 “IT and Telecom – Storage Products (Hardware and Perpetual License Software),” and storage-related service PSCs such as DK01 Storage Support Services. These PSCs describe what is being purchased and can accompany a NAICS like 334112. ³
