NAICS 333991

Overview

The North American Industry Classification System (NAICS) is the federal statistical standard for classifying business establishments to collect, analyze, and publish data on the U.S. economy. Developed under the Office of Management and Budget and adopted in 1997 to replace SIC, NAICS was created jointly with Statistics Canada and Mexico’s INEGI and is currently implemented in the 2022 vintage. ¹

NAICS 333991 covers establishments primarily engaged in manufacturing power-driven handtools—battery-powered, corded electric, or pneumatic—including drills, screwguns, circular saws, chain saws, staplers, and nailers. Federal statisticians and procurement analysts use this code to delineate production of handheld powered tools from adjacent machinery and nonpowered hand tools. ²

2022 NAICS adoption timeline (context)

• The Census Bureau began publishing data using 2022 NAICS with the 2022 Economic Census First Look in January 2024; broader 2022 Economic Census releases and other series followed in late 2024. ³
• Most Census economic programs transition to 2022 NAICS by end of calendar year 2027 (with VIUS moving in 2028 and the Commodity Flow Survey in 2030). ³

Frequently asked questions

• What does NAICS 333991 include?

  • It includes manufacturing of power-driven handheld tools, such as drills, screwguns, circular saws, chain saws, staplers, and nailers. Coverage spans battery-powered, corded electric, and pneumatic types used in commercial, industrial, and consumer applications, distinguishing them from nonpowered hand tools and larger stationary machinery. ²

• Are cordless and pneumatic tools both in 333991?

  • Yes. Establishments making battery-powered (cordless), corded electric, and pneumatic handheld power tools are all classified here. The category is defined by the tool being handheld and power-driven, regardless of power source, including air-driven nailers, staplers, and spray devices designed for handheld use. ²

• Are handheld pneumatic spray guns classified here?

  • Generally, yes. When a spray gun is designed and marketed as a handheld power-driven tool, it falls within this industry. Larger non-handheld spray systems or pumping equipment would be classified elsewhere under machinery subsectors rather than in handheld power-driven handtools. ²

• Which NAICS covers nonpowered hand tools?

  • Nonpowered hand and edge tools are classified under 332212 (Hand and Edge Tool Manufacturing), while blades and handsaws are covered under 332213. This separation keeps manual tools distinct from power-driven handheld tools in 333991. ²

• Which PSCs often tag buys for power-driven hand tools?

  • PSC 5130 (“Hand Tools, Power Driven”) is most common. Related PSCs include 5110 (Edged, Nonpowered), 5120 (Nonedged, Nonpowered), and mixed kits under 5180. Use PSCs with NAICS to refine market research and categorize procurements. ⁵
