NAICS 333310: Commercial and Service Industry Machinery Manufacturing — Federal Contracts

What NAICS 333310 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 333310 identifies businesses primarily engaged in 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.
