Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing industrial and commercial electric apparatus and other equipment (except lighting equipment, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, and carbon and graphite products). Examples of products made by these establishments are power converters (i.e., AC to DC and DC to AC), power supplies, surge suppressors, and similar equipment for industrial-type and consumer-type equipment.

FY2025 federal contract obligations, USAspending.gov
NAICS 335999 obligated $628 million in FY2025 across 13,151 contract awards, an average near $48,000. DoD is $570 million, or 91 percent, with DOT at $20 million, Interior at $11 million, DOJ at $9 million, and VA at $5 million. The transaction profile is sustainment: many small orders against equipment already in the field.
What belongs here
Industrial and commercial electric apparatus and equipment that is not lighting, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, or carbon and graphite products. What remains includes power supplies, converters, surge protection assemblies, and specialized electrical apparatus.
- Power, distribution, and specialty transformers are 335311.
- Electronic components below the equipment level are 334419.
- Fabricated metal enclosures and assemblies are 332999.
Competing in this code
The code had 627 IDVs alongside 13,151 awards in FY2025. The 600-employee size standard is one of the tightest employee-based standards in manufacturing, so set-asides here reach genuinely small shops. The practical caution is the same as every residual code: buyers search the specific electrical equipment code first. If you make power supplies, say so in your capability statement in the buyer's language, because the code itself communicates nothing except that eleven other categories did not fit.
NAICS 335999 FAQ
What is the SBA size standard for NAICS 335999?
SBA sets it at 600 employees, counted as a 24-month average headcount across your company and every affiliate, not revenue. At or under that number you are small on NAICS 335999 solicitations and eligible for the set-asides in this code.
Which agencies buy under NAICS 335999?
FY2025 obligations: DoD ($570 million), DOT ($20 million), Interior ($11 million), DOJ ($9 million), VA ($5 million). DoD at 91 percent across 13,151 small awards describes sustainment demand behind fielded electrical equipment, not new program buys.
What does NAICS 335999 actually cover?
Electrical apparatus left over after eleven named categories are excluded, including lighting, appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, wire and cable, and wiring devices. In federal practice it captures power supplies, converters, surge protection assemblies, and specialized apparatus that no named code describes.
Does the 600-employee size standard help here?
Yes. It is among the tightest employee-based standards in the manufacturing sector, so set-asides in this code reach genuinely small shops; mid-cap manufacturers do not qualify. That is a real advantage in a code where 13,151 FY2025 awards averaged around $48,000 and large firms have little reason to chase individual awards.
