By law, Federal Prison Industries (FPI) is not permitted to sell its goods on the open market, it can only sell to other agencies within the federal government. Still, the growing capabilities of prison-based manufacturing make their products increasingly attractive to government contract buyers. FPI's biggest buyer is the Defense Department -- The DOD gives FPI close to 60 percent of its sales annually. Other regular buyers are the Department of Justice, Department of Homeland Security, Social Security Administration, Postal Service and the General Services Administration. Agencies have all been strongly urged to support FPI as evidenced in a memo on UNICOR's website from Attorney General Eric Holder himself. FPI also sells manufactured goods right back to its sister entity, the Bureau of Prisons. --- 1.
