The size standard associated with NAICS 541990 is $6.5 Million (effective July 31, 2006), which means that a company, including its affiliates, would be considered a "small business" if their average annual gross revenue does not exceed $6.5 Million for the past three years.

Total reported spending under NAICS 541990 in FY03 was over $3.7 Billion. FY04 saw a slight increase, to over $3.9 Billion. Spending for FY05 and FY06 are not as widely reported as the previous fiscal years, so those values are lower ($3.1 Billion for FY05 and $2.6 Billion for FY06). This does not necessarily mean those years saw decreased spending, rather, it indicates that many agencies have not reported all of their contract data to the FPDS yet. These numbers may increase as more departments and agencies report their contract spending.


The Department of Defense (DoD) was the largest buyer for these services for the last four fiscal years (FY03 through FY06), with almost $8.0 Billion in contract spending, comprising almost 60% of the market share for NAICS 541990. This value may include all components of the Defense Department (Army, Navy, Air Force, DLA, etc.), however, FY05 and FY06 contract dollars have not been as widely reported yet (at least as far as FPDS data).

The Department of Homeland Security (DHS) was a distant second, with just under $1.4 Billion over the same period. NASA followed closely behind in third place, with over $1.2 Billion and just over 9% of the market share. The United States Agency for International Development (AID aka USAID) and the Department of Health and Human Services (HHS aka DHHS) rounded out the top five.
