I think Switzerland and germany are the only ones to require RFID taggants in each batch.
Switzerland requires taggants in some explosives (not all) but doens't require them to be uniqe by batch. Their law requires that the taggants be changed every 6 months of production or every 150 tons produced, which ever comes first.
But even the National Acad. of Science, who conducted an assesment of taggants post OKC and 9/11, says that the technology isn't there for their use to be feasible to this point in time. (See their report: "Containing the Threat from Illegal Bombings: An Integrated National Strategy for Marking, Tagging, Rendering Inert, and Licensing Explosives and Their Precursors")
