NAICS 334510

Overview

The North American Industry Classification System (NAICS) is the federal standard for grouping business establishments so statistical agencies can collect, analyze, and publish data about the U.S. economy. Created by the Economic Classification Policy Committee and adopted by OMB in 1997 to replace SIC, NAICS also supports comparability with Canada and Mexico. ¹

NAICS 334510 covers establishments primarily engaged in manufacturing electromedical and electrotherapeutic apparatus, including MRI and ultrasound equipment, pacemakers, hearing aids, electrocardiographs, and electromedical endoscopic equipment. Federal statistical releases for the 2022 Economic Census use the 2022 NAICS vintage. ²

Scope notes and cross‑references

• Medical irradiation apparatus (e.g., X‑ray therapy units) are classified in NAICS 334517, not in NAICS 334510. ³
• Nonelectrical medical and therapeutic apparatus (e.g., surgical instruments without electronic components) fall under NAICS industry group 3391, not NAICS 334510. ³
• Laboratory analytical instruments are NAICS 334516, except instruments for monitoring and analyzing continuous medical patient samples, which are NAICS 334510. ³
• The parent hierarchy places NAICS 334510 under 31–33 Manufacturing → 334 Computer and Electronic Product Manufacturing → 3345 Navigational, Measuring, Electromedical, and Control Instruments → 33451. ³

Frequently asked questions

• What products are included in NAICS 334510?
  Establishments classified in NAICS 334510 manufacture electromedical and electrotherapeutic apparatus such as MRI and ultrasound equipment, pacemakers, hearing aids, electrocardiographs, and electromedical endoscopes. These are production activities, not service delivery. ³

• How does NAICS 334510 differ from NAICS 334517?
  NAICS 334510 covers non‑ionizing electromedical/electrotherapeutic devices (e.g., MRI, ultrasound, pacemakers). NAICS 334517 covers irradiation apparatus and tubes for medical diagnostic/therapeutic and other ionizing‑radiation uses (e.g., X‑ray, gamma). ³

• Are software‑only medical imaging products classified under NAICS 334510?
  Not specified by official sources ³

• Which PSCs commonly align to purchases of 334510‑type products?
  PSC 6515 (Medical and Surgical Instruments, Equipment, and Supplies) and PSC 6525 (Imaging Equipment and Supplies: Medical, Dental, Veterinary) cover many relevant medical devices and imaging systems used in federal procurement. ⁴

• Where does NAICS 334510 sit in the NAICS hierarchy?
  It is a U.S. national industry under NAICS 33451 within industry group 3345, subsector 334 of sector 31–33 Manufacturing. ³
