FY2025 federal contract obligations, USAspending.gov
NAICS 333310 obligated $1.1 billion in FY2025 across 5,113 contract actions, 98 percent of it DoD. State and Treasury follow at about $7 million each, VA at $5 million. But the headline number understates the market, because federal systems are still writing awards against 333318, the 2017 code that NAICS 2022 folded into this one, and that legacy code carried another $605 million in FY2025.
What belongs here
Commercial and service industry machinery: optical instruments and lenses other than ophthalmic, photographic and photocopying equipment, automatic vending machinery, commercial laundry and drycleaning machinery, office machinery, automotive maintenance equipment other than mechanics hand tools, and commercial cooking equipment.
- General purpose machinery outside these categories is 333998.
- Construction, mining, and logging machinery is 333120.
- Office furniture belongs under 337214.
Competing in this code
258 IDVs against 5,113 actions leaves substantial open competition. The practical instruction is to search both codes. If your SAM registration carries only 333310, you are invisible to any buying office still using 333318, and roughly a third of the combined market sits there. Register the current code as primary, keep the legacy code active where your registration allows it, and set opportunity alerts on both. The DoD concentration means the recurring buys are optics, field laundry, and commercial cooking equipment for deployed and installation use.
Frequently Asked
NAICS 333310 questions, answered.
What is the SBA size standard for NAICS 333310?
SBA sets it at 1,000 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 333310 solicitations and eligible for the set-asides in this code.
Which agencies buy commercial and service industry machinery under NAICS 333310?
FY2025 obligations: DoD ($1.1 billion), State ($7 million), Treasury ($7 million), VA ($5 million), DOJ ($2 million). DoD at 98 percent drives recurring optics, field laundry, and commercial cooking equipment demand for installation and deployed use.
Why does spending still appear under NAICS 333318?
Because NAICS 2022 merged the 2017 codes 333314, 333316, and 333318 into 333310, and federal contract writing systems carry legacy codes on existing vehicles and options. FY2025 shows $1.1 billion under 333310 and another $605 million under 333318. Any market sizing that ignores the legacy code understates the total by about a third.
Should I register under both 333310 and 333318?
Register 333310 as your current code, and keep 333318 active wherever your SAM registration and vehicle listings still permit it. Buying offices working from older vehicle documents search the legacy code, and a registration that carries only the 2022 code will not surface in those searches.
