Dear Balajee
I am not sure I catch your question. Therefore the othr way around:
a.) you define a material; by doing so you need to define "mass" etc. (1000 kg); now the DG people need to understand if this material with this mass etc. is allowed to be transported by rail etc. If so they simply release the DG master per regulation
b.) or do we talk about the topic "Reportable Quantity and to a certain extent "Limited Quantity"?
