NAICS 335929

Overview

The North American Industry Classification System is the framework federal statistical agencies use to categorize establishments for producing, analyzing, and publishing data on the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS is jointly maintained by the U.S., Canada, and Mexico and is currently published in the 2022 vintage. ¹

NAICS 335929 — Other Communication and Energy Wire Manufacturing — covers establishments primarily engaged in manufacturing insulated wire and cable of nonferrous metals from purchased wire. Cross-references direct cable set manufacturing to NAICS 334419, cord sets from purchased insulated wire to NAICS 335999, and integrated wire drawing plus insulating to NAICS 331422, 331319, or 331491, as applicable. Fiber-optic cable manufacturing is classified in NAICS 335921. ²

Key cross-references and exclusions

• Cable sets with connectors for electronic applications are classified in NAICS 334419. ²
• Extension/appliance cord sets made from purchased insulated wire are classified in NAICS 335999. ²
• Drawing and insulating copper wire in one establishment falls under NAICS 331422; aluminum under NAICS 331319; other nonferrous metals under NAICS 331491. ²
• Fiber-optic cable (insulated optical fiber) belongs in NAICS 335921, not in NAICS 335929. ²

Frequently asked questions

• What activities define NAICS 335929?

  • It comprises establishments primarily engaged in manufacturing insulated wire and cable of nonferrous metals from purchased wire. Activities that combine drawing and insulating in one site, or that make connectorized cable sets, are classified elsewhere. ²

• How is NAICS 335929 different from NAICS 335921?

  • NAICS 335929 covers insulated nonferrous metal conductor wire and cable. NAICS 335921 covers insulated fiber-optic cable from purchased optical strand. They are mutually exclusive by conductor type. ²

• Does NAICS 335929 include wire drawing?

  • No. If the establishment draws and insulates wire in the same facility, classification shifts to NAICS 331422 for copper, NAICS 331319 for aluminum, or NAICS 331491 for other nonferrous metals. ²

• Which PSCs commonly align to products under NAICS 335929?

  • Common product service codes include PSC 6145 (Wire and Cable, Electrical) and PSC 5995 (Cable, Cord, and Wire Assemblies; Communication Equipment), per the PSC Manual. ³

• What small business size standard applies to NAICS 335929?

  • SBA assigns employee-based size standards for manufacturing industries by NAICS code. See SBA’s Table of Small Business Size Standards for the current threshold applicable to NAICS 335929. ⁵
