i'm not going to answer your question.
Cared to use the forum SEARCH feature?
seems like you registered to only inquire about your customs issue.

no iwill use in future first i have to understand what is my issue..please help me

Sure. We are here to help only. But unfortunately the customs have confiscated your drone. If it's that pricey you can contact any private customs agent they will bring it out hopefully legally. Drones are illegal to import. But it's ok we all make mistakes. Please search this forum for more info on customs issue. I am sure you will naturally find more info. Welcome to this grand hobby. Looking forward to get more posts from you. 

As @ modeler321 said,
The customs have confiscated your quadcopter.
In my opinion, you should ask them to send it back.
Not worth investing an agent for a mini drone.
Regards

That's better.

then what is that word- "FOR FINAL DELIVERY"

it means that the mail carrier has "washed their hands off your consignment - and turned it over to the
customs - to decide whether it has to be delivered "

basically another way of saying that the customs has seized your parcel.
