MMDG form trigger for Regulated material ..

Hi,

We got a query from our client,They are going ship same material in different type of carriage (1. In containers,2. In Ro-Ro shipping),in this one will comes under regulatory which are going through containers because we don't know what will happen inside the container while transporting, MMDG form will trigger for this kind of transport. Ro Ro shipping will not comes under regulatory as per the client.

After the out bound delivery we got to know either material will be shipped through container or Ro Ro, So i want to differentiate these after the outbound delivery for triggering the MMDG form. Where can i differentiate ?? Please give some ideas on this.....

Thanks
