NAICS 333922 – Conveyor and Conveying Equipment Manufacturing encompasses the design, fabrication, and assembly of industrial conveying systems used to transport materials, components, and finished goods in automated production and logistics environments. This includes belt conveyors, roller conveyors, chain drives, pneumatic conveyors, and specialized material handling systems integrated into manufacturing plants, warehouses, and distribution centers. In government contracting, these systems support mission-critical operations in defense logistics, veterans’ medical facility operations, and military supply chain infrastructure, where reliability, durability, and compliance with federal specifications are paramount. The sector bridges heavy industrial manufacturing with federal operational needs, requiring precision engineering, corrosion-resistant materials, and often custom integration to meet stringent military or healthcare facility standards. Top contractors in this space include LINDE GAS & EQUIPMENT INC., a leading provider of engineered material handling solutions with deep experience in federal procurement. These contractors are typically large primes with in-house engineering capabilities and certified manufacturing facilities, often partnering with small businesses for specialized components or installation services. The competitive landscape is dominated by firms with ISO-certified production processes and experience navigating federal acquisition regulations for custom equipment. The Department of Veterans Affairs and the Department of Defense are the primary federal buyers, procuring conveying systems for automated pharmaceutical distribution in VA medical centers, munitions handling in defense depots, and logistics automation in military supply chains. Demand is driven by modernization initiatives to improve efficiency, reduce manual labor, and enhance safety in high-volume operational environments. The market offers steady opportunity density for contractors with proven expertise in ruggedized material handling systems and federal compliance. Growing emphasis on automation in federal facilities and the need for modular, scalable conveyance solutions present clear pathways for innovation-driven suppliers with validated technical capabilities and experience in defense and healthcare infrastructure projects.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 333922 work as a small business.

500 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
