NAICS 339114

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying business establishments to produce consistent statistics about the U.S. economy. Developed under the Office of Management and Budget with Canada and Mexico, NAICS replaced SIC in 1997 and is maintained in five-year revisions; the current vintage is 2022. ¹

NAICS 339114 covers establishments primarily engaged in manufacturing dental equipment and supplies for laboratories and dentists’ offices, such as dental chairs, instrument delivery systems, hand instruments, impression materials, and cements. Agencies and data users rely on this code to classify production activity and publish industry statistics, and the 2022 NAICS Manual provides the official scope, inclusions, and exclusions. ²

What this NAICS covers

• Manufacture of dental operatory furniture and chairs used in clinical settings. ²
• Production of dental instrument delivery systems and integrated units. ²
• Manufacture of dental hand instruments (e.g., scalers, excavators, pluggers). ²
• Formulation of dental impression materials and related consumables. ²
• Production of dental cements, liners, and similar restorative materials. ²
• Specialized dental laboratory apparatus and furniture. ²

Frequently asked questions

• What products fall under NAICS 339114?

  • Covered products include dental operatories and chairs, instrument delivery systems, hand instruments, impression materials, cements, and specialized dental laboratory apparatus and furniture. The focus is manufacturing of equipment and standardized consumables for dental practices and labs, not custom patient-specific prosthetics. ²

• How does NAICS 339114 differ from NAICS 339116?

  • NAICS 339114 covers manufactured dental equipment and standardized supplies. NAICS 339116 covers patient-specific dental laboratories producing dentures, crowns, bridges, and orthodontic appliances. The distinction hinges on standardized manufacturing versus custom fabrication for individual patients. ²

• Which PSC codes commonly align to dental equipment and supplies in federal awards?

  • PSC 6520 (dental instruments, equipment, and supplies) and PSC 6525 (medical, dental, and veterinary imaging equipment and supplies) are frequently applied when specifying dental operatories, hand instruments, and imaging devices in solicitations and awards. ⁴

• Are dental X-ray manufacturing activities included in NAICS 339114?

  • No. Manufacturing irradiation apparatus, including many X-ray devices and associated equipment, is classified in NAICS 334517, not NAICS 339114. Dental imaging supplies and equipment may align to PSC 6525 for procurement purposes. ²

• When was NAICS adopted and what is the current version?

  • NAICS was adopted in 1997 to replace SIC and is jointly maintained by the U.S., Canada, and Mexico. The current version is 2022, which agencies and statistical programs implement on their own schedules following Census guidance. ¹
