NAICS 334412

Overview

The North American Industry Classification System (NAICS) is the federal statistical standard for grouping business establishments by production process to enable consistent collection and publication of U.S. economic data. Developed under the Office of Management and Budget in coordination with Canada and Mexico, NAICS replaced SIC in 1997 and is updated every five years, with the current vintage being 2022. ¹
U.S. industry NAICS 334412 covers manufacturing of bare, rigid or flexible printed circuit boards without mounted electronic components. Establishments in this industry print, perforate, plate, screen, etch, or photoprint conductive pathways on laminates. Assembling electronic components onto printed circuit boards is classified elsewhere. ²

Frequently asked questions

• What activities are in-scope for NAICS 334412?
  Manufacturing bare printed circuit boards—rigid or flexible—by printing, perforating, plating, screening, etching, or photoprinting conductive pathways on laminates. It excludes any mounting of electronic components or shipment of loaded boards. ²

• Does loading components onto a PCB fall under NAICS 334412?
  No. Loading components onto printed circuit boards (i.e., printed circuit assemblies) is classified in NAICS 334418. See also on G2X: NAICS 334418. ²

• Are printed circuit laminates part of NAICS 334412?
  No. Manufacturing printed circuit laminates falls under NAICS 334419, not NAICS 334412. See also on G2X: NAICS 334419. ²

• How is NAICS used in federal procurement contexts?
  While NAICS is designed for statistical classification, agencies often adopt it for administrative, regulatory, and contracting purposes such as setting size standards, organizing market research, and classifying solicitations and awards. ⁵

• What does “2022 NAICS vintage” mean for programs and data?
  The Census Bureau began publishing data on the 2022 NAICS basis with Economic Census releases in 2024, and most statistical programs are expected to adopt 2022 NAICS by the end of calendar year 2027. ³
