NAICS 334417

Overview

The North American Industry Classification System (NAICS) is the federal standard for organizing business establishments to support the collection, analysis, and publication of U.S. economic statistics. Created under the Office of Management and Budget (OMB) and adopted in 1997 to replace SIC, NAICS was developed jointly by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s INEGI to enable comparability across North America; the current vintage is 2022. ²

NAICS 334417 covers establishments primarily engaged in manufacturing electronic connectors, including coaxial, cylindrical, rack-and-panel, pin-and-sleeve, printed circuit, and fiber-optic types. Electrical connectors such as plugs, bus bars, twist-on wire connectors, and terminals are excluded and classified in NAICS 335931; other electronic components (except connectors) fall under NAICS 334419. ¹

Federal data availability and vintage

• Census Bureau economic programs are migrating from 2017 to 2022 NAICS; the 2022 Economic Census began publishing on the 2022 basis in 2024, with full adoption across most programs expected by the end of calendar year 2027. ²
• Manufacturing statistics for 2022 by NAICS sector (including NAICS 334417) are accessible via the Economic Census Manufacturing tables. ³

Frequently asked questions

• What products fall under NAICS 334417?

  • Electronic connectors manufactured for electronic applications, including coaxial, cylindrical, rack-and-panel, pin-and-sleeve, printed circuit, and fiber-optic connectors. These are distinct from electrical wiring devices such as plugs and terminals. ¹
    See also on G2X: NAICS 334417.

• How does NAICS 334417 differ from NAICS 335931?

  • NAICS 334417 covers electronic component-type connectors. NAICS 335931 covers current-carrying wiring devices (e.g., plugs, bus bars, twist-on connectors, terminals) used in electrical wiring circuits. ¹

• Are printed circuit assemblies part of NAICS 334417?

  • No. Loading components onto printed circuit boards and producing loaded boards are classified in NAICS 334418 (Printed Circuit Assembly/Electronic Assembly), not in NAICS 334417. ¹

• Does NAICS 334417 include fiber-optic connectors?

  • Yes. Fiber-optic connectors are explicitly listed among the examples included in NAICS 334417. ¹

• Did the 2022 NAICS revision change the definition of NAICS 334417?

  • Not specified by official sources ². The Census Bureau describes the 2022 transition and provides a changes file, but per-industry change details for NAICS 334417 are not specified on the public overview pages.
