NAICS 336999: All Other Transportation Equipment Manufacturing — Federal Contracts

What NAICS 336999 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 336999 identifies businesses primarily engaged in all other transportation equipment 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.
