NAICS 333924

Overview

The North American Industry Classification System (NAICS) is the government-wide standard for organizing U.S. business establishments so agencies can collect, analyze, and publish economic statistics. Developed under the Office of Management and Budget and adopted in 1997, NAICS is jointly maintained by the U.S., Canada, and Mexico and is currently published on the 2022 vintage. ¹

NAICS 333924 covers establishments primarily engaged in manufacturing industrial trucks, tractors, trailers, and truck‑type stacker machinery, including forklifts, pallet loaders/unloaders, and portable loading docks. Census cross‑references place motor‑vehicle type trailers in NAICS 336212, farm tractors in NAICS 333111, and construction‑type tractors in NAICS 333120. ²

Frequently asked questions

• What products fall under NAICS 333924?
  Census defines this industry as manufacturers of industrial trucks, industrial tractors (non‑farm/non‑construction), in‑plant industrial trailers, and truck‑type stackers such as forklifts, pallet loaders/unloaders, portable loading docks, and aircraft loading hoists. This is a production‑oriented classification. ² See also on G2X: NAICS 333924

• How does NAICS 333924 differ from NAICS 336212 and 333120?
  On‑road motor vehicle‑type trailers belong to NAICS 336212. Construction‑type tractors go to NAICS 333120. NAICS 333924 focuses on industrial, truck‑type material handling equipment made for plant or warehouse use. ²

• Are aircraft loading hoists included in NAICS 333924?
  Yes. Aircraft loading hoists are explicitly cross‑referenced to NAICS 333924 within the Material Handling Equipment Manufacturing industry definition. ²

• What is the current NAICS vintage for economic statistics?
  The 2022 Economic Census and related guidance use the 2022 NAICS vintage. NAICS was adopted in 1997 under OMB and is maintained jointly by the U.S., Canada, and Mexico to support consistent industry statistics across North America. ¹

• Does NAICS 333924 distinguish by power source (e.g., electric vs. internal combustion) or autonomy?
  Not specified by official sources. In general, NAICS groups establishments by production processes rather than product technology variants unless a distinction is explicitly defined in the industry description. ¹
