NAICS 335314 – Relay and Industrial Control Manufacturing covers the design, production, and assembly of electromechanical relays, programmable logic controllers (PLCs), industrial switches, timing devices, and other control systems used to automate and regulate machinery, power distribution, and process operations. These components are critical for mission-critical infrastructure, including defense systems, energy grid management, transportation control, and environmental monitoring applications. In government contracting, this NAICS supports the integration of ruggedized, high-reliability control hardware into military platforms, federal facility automation, and remote operational environments where precision and durability are non-negotiable. Products in this category often require compliance with MIL-STD specifications and must function reliably under extreme conditions, making them essential to national security and infrastructure resilience. Top contractors in this sector include POWER WEST ENGINEERING LLC and EVERSTONE INDUSTRIES LLC, both of which are small businesses specializing in custom industrial control assemblies and ruggedized relay systems tailored for federal applications. These firms compete in a niche but high-barrier market where engineering expertise, certification compliance, and supply chain traceability are decisive advantages over larger manufacturers. The Department of the Interior and the Department of Defense are the primary federal buyers, procuring these components for automated environmental sensing systems, remote facility power controls, and embedded control units in defense platforms. Demand is driven by modernization initiatives for aging infrastructure, battlefield automation, and energy resilience programs in remote installations. The competitive landscape is concentrated among specialized small businesses with deep domain knowledge in industrial automation and government-grade ruggedization. Opportunities exist for firms capable of delivering certified, low-volume, high-reliability control systems with rapid prototyping and qualification capabilities, particularly those aligned with DoD’s modernization priorities and Interior’s infrastructure resilience goals.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 335314 work as a small business.

750 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.
