ISN/MBC leads the USG effort to identify and stop specific shipments of missile- and CBW-related items of concern worldwide, including by chairing the relevant interdiction working groups.


ISN/MBC implements U.S. missile and CBW sanctions laws, missile and CBW-related Executive Order (E.O.) 12938 penalties, and the Iran, North Korea, and Syria Nonproliferation Act. Much of this work is facilitated by and coordinated through the interdiction working groups. More»

ISN/MBC regularly provides the following reports to Congress: “Proliferation of Missiles and Essential Components of Nuclear, Chemical and Biological Weapons”; the national emergency with respect to the proliferation of weapons of mass destruction; INKSNA; countries’ adherence to the MTCR; and the “Annual Certification to Congress on the Effectiveness of the Australia Group.”

Hague Code of Conduct Against Ballistic Missile Proliferation

The Hague Code of Conduct Against Ballistic Missile Proliferation (HCOC) was formally brought into effect on November 25, 2002, at a launching conference hosted by the Netherlands in The Hague. The HCOC is aimed at bolstering efforts to curb ballistic missile proliferation worldwide and to further delegitimize such proliferation. The HCOC consists of a set of general principles, modest commitments, and limited confidence-building measures. It is intended to supplement, not supplant, the Missile Technology Control Regime, and is administered collectively by all of the subscribing states. For more information about the HCOC, visit More»
