Which data does your Dutch customs agent require from you?
In order to quickly and correctly submit subsequent declarations, your Dutch customs agent will require the following data from you as the shipper, or the forwarder or carrier acting on your behalf, in a timely manner:
The shipment number as issued to you (as the shipper), your forwarder or your carrier by the shipping line, cargo handling agent or ferry operator upon booking
The gross weight of the load and the number of packaging units
Without this information, the Dutch customs agent will not be able to make a correct subsequent declaration and the cargo will definitely come to a standstill at the terminal!
