NAICS 326220

Overview

The North American Industry Classification System (NAICS) is the federal standard for organizing business establishments to enable consistent collection, analysis, and publication of statistics on the U.S. economy. Developed under the Office of Management and Budget, NAICS replaced the SIC in 1997 and is maintained jointly with Statistics Canada and Mexico’s INEGI; the current U.S. vintage is 2022. ²

NAICS 326220 covers establishments primarily engaged in manufacturing rubber hose and/or reinforced plastics hose and belting from natural or synthetic rubber and/or plastics resins; manufacturers that make garden hoses from purchased hose are included. Census cross‑references place rubber tubing in 326299, plastics tubing in 326121, and fluid power hose assemblies in 332912. ¹

Frequently asked questions

• What products fall under NAICS 326220?

  • Establishments make rubber hose, reinforced plastics hose, and rubber/plastics belting. Making garden hoses from purchased hose is included. The code covers hose and belting produced without fittings. ¹

• How is NAICS 326220 different from 326121?

  • Plastics tubing and other unsupported plastics profile shapes (rod, tube, casings) fall under 326121, while reinforced plastics hose is in 326220. The distinction hinges on product type and production process. ¹

• Are hose assemblies with fittings counted in 326220?

  • Fluid power hose assemblies are classified in 332912, not 326220. NAICS 326220 covers hose and belting manufactured without fittings. ¹

• Is 326220 defined consistently across the U.S., Canada, and Mexico?

  • Yes. The 2022 NAICS manual indicates NAICS 326220 is comparable across the three countries (marked “T”). ¹

• Which PSCs commonly align to purchases in this space?

  • PSC 4720 covers hose and flexible tubing, while PSC 3030 covers belting and drive belts. Fittings often fall under PSC 4730. ³
