After the shipment arrives, customs impose duties and taxes on it and inform the carriers, and then the carrier conveys this to the recipient to collect payment and finds him unreachable. This makes for a perfect delays scenario. So the receiver should be aware about the delivery and contact the carrier to avoid delays. There is always a chance that customs can raise a query on the shipment’s customs invoice. Then they require an explanation on the form. The time taken to resolve the query can cause delays. Inspection by customs leads to the discovery of items undervalued or undeclared will hinder the clearance process significantly. The customs officer could ask to provide a proof of value, and may even ask for more clarification on the items. So always declare information accurately. Customs hold shipments containing restricted or prohibited. In most cases, the customs will give options to destroy or remove the prohibited items. For some destination, there are chances that the shipment can return to origin at shippers cost.
