When you will get EP copy after export?

If dealing directly with airlines, you can get the ep copy at the same time with shipping bill / exchange control copy..

When the shipment is through an iata agent, the ep copy is retained with the cha , as they give it to the airlines for updating the records in their edi system.

Some agents, keeps the ep copy with them in order to get their outstanding cleared....

An organised cha or forwarder could give you the ep copy within a week after the shipment is made.
