Indonesian Tutorial for Producing Urea Dinitro Perchlorate HME

May 28, 2016

In August 2015, Indonesian IS-member Bahrun Naim uploaded an Indonesian-language tutorial for the production of an HME he identified as Urea Dinitro Perchlorate (UDP) to his website. The tutorial describes, in brief, the composition of the substance, method of preparation, and two possible mixtures, stating that the so-called UDP HME was successfully tested. However, despite claims of a successful test detonation, we assess the tutorial to be highly problematic as there is no known explosive called UDP, and the molecular formula, recipe and procedure articulated by Naim for producing the so-called UDP HME is unlikely to even result in its creation.
