NAICS 336213

Overview

The North American Industry Classification System (NAICS) is the federal standard for classifying U.S. business establishments to support the collection, analysis, and publication of economic statistics. Developed under the Office of Management and Budget in 1997 to replace SIC and jointly maintained with Canada and Mexico, federal statistical programs are transitioning to the 2022 NAICS vintage as implementation proceeds across datasets and tools. ²

NAICS 336213 — Motor Home Manufacturing — covers establishments primarily engaged in manufacturing motor homes on purchased chassis and/or producing conversion vans on an assembly‑line basis. Motor homes are defined as integrated units that combine the motor and living quarters. Census cross‑references clarify boundaries with light‑duty vehicle, heavy‑duty truck, repair/customization services, and manufactured homes industries. ¹

What this NAICS covers

• Assembly of self‑contained motor homes on purchased motor‑vehicle chassis. ¹
• Assembly‑line production of conversion vans as complete vehicles. ¹
• Manufacturing where the motor and living quarters form a single integrated unit. ¹
• Producing complete motor homes for highway use, using chassis obtained from other manufacturers. ¹
• Selling completed motor homes assembled on purchased chassis (as opposed to chassis manufacturing). ¹
• Manufacturing motor homes distinct from towable travel trailers and campers. ¹

Frequently asked questions

• What activities define NAICS 336213?

  Establishments primarily manufacture motor homes on purchased chassis and/or produce conversion vans on an assembly‑line basis. The defining feature is a self‑propelled, single unit that integrates the motor and living quarters; towable units and stand‑alone interior customizations are excluded. ¹

• How is 336213 different from 336214?

  336213 covers self‑propelled motor homes, while 336214 covers towable travel trailers and campers that lack their own motor. The products, production processes, and regulatory contexts differ accordingly, reflecting self‑propulsion versus towable configuration. ¹

• Are conversion vans included in 336213?

  Yes. Conversion vans are included when produced as complete vehicles on an assembly‑line basis. However, individual or one‑off interior customization work is not included and is classified under 811121 (automotive body, paint, and interior repair and customization). ¹

• Does 336213 include manufactured (mobile) homes?

  No. Manufactured housing is classified under 321991. NAICS 336213 is limited to self‑propelled motor homes (and assembly‑line conversion vans) and excludes factory‑built dwellings designed for transport to a site as a residence. ¹

• Were there code‑specific changes to 336213 in NAICS 2022?

  Not specified by official sources. The Census Bureau’s 2022 NAICS implementation overview addresses transition timing and adoption across programs but does not provide a code‑level change note for 336213. ³
