NAICS 334418

Overview

The North American Industry Classification System (NAICS) is the federal standard for organizing establishments to produce comparable statistics on the U.S. economy. Developed by the U.S. Economic Classification Policy Committee with Statistics Canada and Mexico’s INEGI, NAICS was adopted by OMB in 1997 to replace the SIC system; the current vintage is 2022. ¹
U.S. industry 334418 covers establishments that load components onto printed circuit boards and manufacture/ship “loaded” printed circuit boards (printed circuit assemblies, electronics assemblies, or modules) used as inputs to many electronic systems and devices; finished end products that incorporate loaded boards are classified by the final product’s production process. ²

What this NAICS covers

• Loading electronic components onto printed circuit boards and producing “loaded” boards (printed circuit assemblies/modules). ²
• Manufacturing and shipping printed circuit assemblies that serve as inputs to a wide variety of electronic systems and devices. ²
• Internal, loaded PCB devices used as computer peripherals (e.g., sound, video, controller, and network interface cards) and internal/external computer modems. ⁴
• Drive controller cards used with storage devices (internal or external to the device). ³
• Electronic subassemblies (assemblies/modules) rather than finished consumer or industrial equipment. ²
• Terminology recognized by Census for this activity includes “printed circuit assemblies,” “electronics assemblies,” and “modules.” ²

Scope notes and exclusions (official cross‑references)

• Manufacturing printed circuit laminates is excluded; see 334419. ²
• Manufacturing bare boards (without mounted components) is excluded; see 334412. ²
• Components or modules for telephone systems are classified in 334210, not 334418. ²
• Finished products that incorporate loaded PCBs are classified by the final product’s manufacturing industry, not in 334418. ²

Illustrative products cited in NAICS cross‑references

• Internal, loaded printed circuit board devices such as sound, video, controller, and network interface cards; and internal or external computer modems (when manufactured as peripherals). ⁴
• Drive controller cards associated with computer storage devices (controller boards). ³

2022 NAICS implementation context

• Census programs began disseminating estimates on a 2022 NAICS basis starting with 2022 Economic Census releases; adoption across all programs continues on the published timeline. ⁵

Frequently asked questions

• What does NAICS 334418 include?
  Establishments that load components onto printed circuit boards and manufacture/ship loaded printed circuit boards (printed circuit assemblies/modules) used as inputs to other electronic equipment. ²

• How is 334418 different from 334412 and 334419?
  334418 covers loaded PCBs; 334412 covers bare boards; 334419 covers other electronic components (e.g., laminates, crystals), not loaded boards. ²

• Are final devices that contain loaded PCBs classified in 334418?
  No. Finished products that incorporate loaded PCBs are classified in the industry for the final product’s manufacturing process (e.g., communications equipment), not in 334418. ²

• Do internal NICs or modems fall under 334418?
  Yes. Cross‑references specify internal, loaded PCB devices (e.g., NICs, sound/video/controller cards) and internal/external computer modems as falling under 334418. ⁴

• Does Census specify assembly methods (SMT, through‑hole) for 334418?
  Census defines the industry by the function of loading components onto PCBs and shipping loaded boards; specific assembly methods are not detailed. Not specified by official sources ².
