NAICS 334413

Overview

The North American Industry Classification System (NAICS) is the framework federal statistical agencies use to categorize business establishments for collecting, analyzing, and publishing data on the U.S. economy. Developed under the Office of Management and Budget with Canada and Mexico, NAICS replaced SIC in 1997 and is revised every five years; current statistical publications use the 2022 vintage. ¹

NAICS 334413 covers establishments primarily engaged in manufacturing semiconductors and related solid-state devices. Official examples include integrated circuits, memory chips, microprocessors, diodes, transistors, solar cells, light‑emitting diodes (LEDs), and other optoelectronic devices. Agencies use this code to classify manufacturing activity and publish industry statistics within Sector 31‑33, Manufacturing. ³

What this NAICS covers

• Fabrication of integrated circuits and microprocessors on semiconductor wafers. ³
• Manufacturing of semiconductor memory devices (“memory chips”). ³
• Production of discrete semiconductors, such as diodes and transistors. ³
• Manufacturing of optoelectronic devices, including solar cells and LEDs. ³
• Other related solid‑state device manufacturing (e.g., certain sensors/optoelectronics). ³
• Establishments whose primary output is semiconductor/solid‑state devices rather than printed circuit boards or finished end‑products. ³

Frequently asked questions

• What products are in scope for NAICS 334413?

  Integrated circuits, memory chips, microprocessors, discrete semiconductors (diodes, transistors), solar cells, LEDs, and other optoelectronic devices are explicitly included. The industry scope focuses on wafer‑level device fabrication and related solid‑state devices, not printed circuit boards or end products. See also on G2X: NAICS 334413. ³

• How is this industry distinguished from printed circuit work or electronics assembly?

  NAICS 334413 covers manufacturing of semiconductor/solid‑state devices. Bare printed circuit boards are classified under 334412, and loaded/assembled boards under 334418. These activities are separate from device fabrication and are not part of semiconductor device manufacturing. ³

• Are LEDs and solar cells covered?

  Yes. Light‑emitting diodes (LEDs) and solar cells are named examples of optoelectronic devices within this industry. Establishments primarily engaged in fabricating these devices on wafers or substrates are included in NAICS 334413, regardless of the end use (e.g., illumination, indicators, or photovoltaic power). ³

• Has the 2022 NAICS revision changed how 334413 is reported, and when will programs adopt 2022 NAICS?

  The Census Bureau began disseminating statistics on a 2022 NAICS basis in 2024. Adoption across all economic programs is scheduled to complete by the end of 2027, with a few survey exceptions. Users should check individual program documentation during the transition. ²

• Which PSC codes often align to semiconductor hardware buys in this space?

  PSC 5961 (Semiconductor Devices and Associated Hardware) and PSC 5962 (Microelectronic Circuit Devices) are the primary product families used for federal procurement reporting of semiconductor devices and microelectronics. Agencies frequently apply these PSCs when buys correspond to device‑level components. ⁴
