The global threats facing the United States have never been greater than they are today. Foreign adversaries are attempting to acquire U.S. technology by various means, both legal and illegal.


Illicit transactions involving our strategic technology not only jeopardize our economic and national security but also endanger the safety of our citizens and soldiers. In today's globalized society, enhanced communications technology and transportation means that rogue states, criminal organizations and terrorist groups have greater potential to acquire and trade nuclear, chemical and biological weapons than ever before. One of Immigration and Customs Enforcement's (ICE) highest priorities is to prevent illicit procurement networks, terrorist groups and hostile nations from illegally obtaining U.S. military products, sensitive dual-use technology, weapons of mass destruction (WMD), or chemical, biological, radiological and nuclear materials. ICE Homeland Security Investigation's (HSI) Counter-Proliferation Investigations (CPI) Program oversees a broad range of investigative activities related to such violations. The CPI Program enforces U.S. laws involving the export of military items, controlled dual-use goods, firearms and ammunition as well as exports to sanctioned or embargoed countries.


The CPI Program prevents sensitive U.S. technologies and weapons from reaching the hands of adversaries. The unit combats the trafficking and illegal export of the following commodities and services:

  • Weapons of mass destruction and associated delivery systems;
  • Military weaponry, equipment and technology;
  • Controlled dual-use commodities and technology;
  • Firearms and ammunition; and
  • Financial and business transactions with sanctioned and embargoed countries and terrorist organizations.

If you have information regarding international terrorism, violations of U.S. export laws, or economic sanctions and embargoes, please call 1-866-DHS-2-ICE (1-866-347-2423; TTY for hearing impaired: 802-872-6196).
