About Transportation and Warehousing Federal Contracting

The Transportation and Warehousing sector (NAICS Sector 48) encompasses 57 individual NAICS codes covering a wide range of business activities. Federal agencies contract extensively within this sector, creating opportunities for small businesses that hold the correct NAICS codes and meet the associated SBA small business size standards.

When registering in SAM.gov, selecting the appropriate NAICS codes from the Transportation and Warehousing sector is essential for appearing in contracting officer searches and qualifying for set-aside programs. Each code within this sector has its own SBA size standard — either revenue-based or employee-based — that determines whether your business qualifies as "small" for contracts solicited under that specific code.
