Industry Definition & Overview
Conveyor and Conveying Equipment Manufacturing (NAICS 333922) encompasses establishments primarily engaged in producing conveyors and conveying equipment for material handling applications across industrial, commercial, and agricultural settings. This classification covers belt conveyors, gravity conveyors, trolley conveyors, tow conveyors, pneumatic tube conveyors, carousel conveyors, farm conveyors, and related material transport systems used in manufacturing plants, distribution centers, airports, and mining operations.
The U.S. Census Bureau[5] identifies approximately 351 active establishments in this sector. Most firms operate as specialized fabricators producing custom conveyor systems tailored to specific facility layouts and throughput requirements. Production involves steel fabrication, welding, machining of rollers and drive components, electrical integration, and controls programming. Regional concentration follows broader manufacturing corridors, with clusters in the Midwest and Southeast where warehouse and distribution infrastructure has expanded.
According to the Bureau of Labor Statistics[6], workers in this sector include mechanical engineers, welders, industrial machinery mechanics, and electrical assemblers. Average establishment size varies widely, from small shops building specialized agricultural conveyors to large operations producing modular systems for e-commerce fulfillment centers. Raw material costs for steel, rubber belting, and electric motors represent a major share of total production expenses.

Key Insight: The SBA[7] classifies NAICS 333922 with a size standard of 500 employees, meaning firms with fewer than 500 workers qualify as small businesses for federal contracting and loan programs. Most conveyor manufacturers fall well under this threshold, as the industry consists largely of mid-size fabrication shops. Small conveyor equipment firms can access SBA 7(a) loans[8] for equipment purchases, facility expansion, and working capital needs. Additionally, 504/CDC loans[9] provide long-term, fixed-rate financing for major fixed assets such as real estate and equipment.

Frequently Asked Questions
Common questions about this industry.
What types of businesses operate in conveyor and conveying equipment manufacturing?
Conveyor manufacturers range from small custom fabrication shops building specialized systems for local clients to large operations producing standardized modular conveyor lines for national distribution. Some firms focus on specific sectors such as mining belt conveyors or food-grade sanitary systems. Others specialize in sortation and automated guided vehicle integration for e-commerce fulfillment centers. Contract engineering firms that design and build complete material handling systems also fall within this classification.
How is the conveyor equipment manufacturing industry structured?
The U.S. Census Bureau[5] reports approximately 351 active establishments in NAICS 333922. Industry structure splits between large integrated manufacturers producing standard product lines and smaller regional fabricators building custom solutions. Steel fabrication, welding, machining, electrical assembly, and controls programming represent core production capabilities. Most manufacturers maintain engineering departments for application-specific conveyor design work.
What is the SBA size standard for conveyor equipment manufacturers?
The SBA[7] sets the size standard at 500 employees for NAICS 333922. Businesses with fewer than 500 full-time equivalent workers qualify as small for federal procurement set-asides and SBA lending programs. Most conveyor manufacturers operate well below this threshold, running facilities with 20 to 150 employees depending on product complexity and production volume.
What NAICS codes are related to conveyor equipment manufacturing?
Several codes share boundaries with NAICS 333922. Elevator and moving stairway manufacturing falls under 333921, covering vertical transport rather than horizontal conveying. Overhead crane and hoist manufacturing (333923) addresses lifting-based material movement. Industrial truck manufacturing (333924) covers forklift and pallet handling vehicles. According to the Census Bureau[10], each code reflects a distinct material handling method and production technology base.
What industries are closely related to conveyor equipment manufacturing?
Warehousing and storage (493110) drives demand for sortation and package handling conveyor systems. Mining operations under 212320 purchase heavy-duty belt conveyors for ore and aggregate transport. Food processing facilities across multiple NAICS codes require sanitary stainless steel conveyor equipment. Automobile manufacturing plants (336111) install extensive conveyor networks for assembly line production. Per the BLS[11], manufacturing sector employment patterns directly influence conveyor equipment demand cycles.
What specific activities fall under NAICS 333922?
NAICS 333922 covers manufacturing of belt conveyors, gravity roller conveyors, trolley conveyors, tow conveyors, pneumatic tube conveyors, carousel conveyors, vibrating conveyors, screw conveyors, and farm conveyors. Production activities include steel frame fabrication, roller and idler machining, belt splicing and vulcanizing, drive unit assembly, electrical controls integration, and system testing. Custom engineering design for specific facility layouts represents a major activity for most manufacturers in this sector.
Can conveyor equipment manufacturers qualify for SBA loans?
Conveyor manufacturers meeting the 500-employee size standard can access multiple SBA loan programs[12]. The 7(a) program provides up to $5 million for equipment purchases, facility improvements, and working capital. Industry 504 program finances real estate and heavy machinery acquisitions through fixed-rate term loans. Manufacturers expanding production capacity or investing in CNC machining centers and robotic welding cells commonly use these programs to finance capital upgrades.
Where are conveyor equipment manufacturers concentrated in the United States?
Conveyor manufacturers cluster in Midwest industrial states including Ohio, Michigan, Illinois, Wisconsin, and Indiana where proximity to steel suppliers and major manufacturing customers reduces logistics costs. The Southeast hosts growing concentrations near automotive plants and distribution hubs in Kentucky, Tennessee, and Georgia. Per the Census Bureau[10], geographic distribution follows broader durable goods manufacturing patterns, with additional clusters near mining operations in western states.
