Firm formerly called Blackwater to pay $7.5m fine over arms sales violations
The agreement means the company will not face prosecution for the 17 alleged counts as long as it meets auditing requirements and complies with export restrictions.
Two years ago Blackwater, which also used the name Xe Services LLC, reached a $42m settlement with the state department for similar allegations.
As a military contractor for the US government in Iraq, Blackwater was a target of intense international scrutiny. In March 2004, four of its security guards were ambushed and killed, and two of their bodies were hung from a bridge in Fallujah.
"This company clearly violated US laws by exporting sensitive technical data and unauthorised defence services to a host of countries around the world," Brock Nicholson, special agent in charge of US immigration and customs enforcement investigations in North Carolina and two other states, said in a written statement.
