Pls find below feedback fm DG expert team in Hamburg :
##quoted##
This material, like most materials in powder form, may capable of creating dual explosion
Further seems that this is a pure substance of Dinitrosopentamethylenetetramine which is not allowed as per 2.4.2.3.2.3 IMDG (82%).
I recommend decline this shipment.

Hence, we cannot accept said DG shpt.
Pls be informed as well.
