Hi Pankaj,

You can go with the agent event "SHIPMENT TENDER - SENT"..Functionally,this event is triggered after the tender is initiated..
If the problem is with triggering the agent,the logs can help you check whether the agent is getting triggered..it is also a possibility that the Saved condition you are using on Item is stopping the process,based on whether the Item you are using in your shipment is hazardous or not..

You can use a sql update to set the "IS_HAZARDOUS" flag in the Shipment table.Sequentially,you can also notify the servprov by ensuring that the contact details are perfect...

Please post again should you require more info ...
