NAICS 333318: Other Commercial and Service Industry Machinery Manufacturing — Federal Contracts

What NAICS 333318 covers

The North American Industry Classification System (NAICS) is the standard the federal government uses to classify the industry of every contractor and every procurement. NAICS 333318 identifies businesses primarily engaged in other commercial and service industry machinery manufacturing. When a contracting officer publishes a solicitation on SAM.gov, they tag it with the NAICS code that best matches the work — which is why getting your NAICS portfolio right inside SAM is the single most important step for showing up in agency searches.
