NAICS 334419

Overview

The North American Industry Classification System (NAICS) is the U.S. government’s standard for classifying business establishments so agencies can collect, analyze, and publish statistics about the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS was jointly created by the U.S. Economic Classification Policy Committee, Statistics Canada, and Mexico’s Instituto Nacional de Estadística y Geografía to ensure comparability across North America. The current vintage is 2022. ¹

NAICS 334419 covers establishments primarily engaged in manufacturing electronic components not elsewhere classified—specifically excluding electron tubes; bare printed circuit boards; semiconductors and related devices; electronic capacitors; electronic resistors; coils, transformers and other inductors; connectors; and loaded printed circuit boards. Census lists “crystals and crystal assemblies” as an illustrative example and provides cross‑references that define boundaries with nearby industries. ²

What this NAICS covers

• Electronic crystals and crystal assemblies (e.g., quartz crystal components and oscillators). ²
• Printed circuit laminates (laminated substrates for printed circuits). ²
• Electronic rheostats and similar variable resistive components classified as “electronic” (distinct from resistor manufacturing). ²
• Electronic component‑type sockets and switches for electronic applications (not wiring‑device switches). ²
• Cable sets consisting of insulated wire with connectors for electronic applications. ²
• Specialized component items such as phonograph and styli needles classified to electronic component manufacturing. ²

SBA small business size standard (summary)

SBA assigns a small business size standard to each NAICS code; for manufacturing industries such as NAICS 334419, the standard is employee‑based. Refer to SBA’s Table of Size Standards (effective March 17, 2023) for the current threshold. ³

Frequently asked questions

• What kinds of products fall under NAICS 334419? Electronic crystals and crystal assemblies; printed circuit laminates; electronic rheostats; component‑type sockets and switches for electronic applications; cable sets with connectors for electronic uses; and certain specialized items like phonograph/styli needles. Census cross‑references define detailed boundaries with adjacent industries. ²

• What is explicitly excluded from NAICS 334419? Electron tubes, semiconductors and related devices, capacitors, resistors, inductors/transformers, connectors, and both bare and loaded printed circuit boards fall under adjacent NAICS codes such as 334411, 334413, 334414, 334415, 334416, 334417, 334412, and 334418. ²

• What SBA size standard applies to NAICS 334419? SBA uses an employee‑based size standard for this manufacturing NAICS. The threshold is published in the SBA Table of Size Standards and is subject to periodic updates; consult the table effective March 17, 2023, or subsequent revisions. ³

• Which PSCs commonly align with components made under NAICS 334419? Common PSCs in solicitations for electronic components include 5961 (Semiconductor Devices and Associated Hardware) and 5962 (Electronic Microcircuits). Always verify definitions and scope in the current Product and Service Code Manual. ⁴
