Parcels are rejected at the mandate of the government of the destination country. This happens for a few reasons. One common reason is that the item is prohibited/restricted. Another common reason is that the sender or recipient did not pay the taxes or duties within the stipulated deadline given by customs.
At this point, there are two options. The first is to return the shipment to you, this may cost you approximately 150% of your original shipping cost. The second option is to have it disposed at the destination country’s customs. Unfortunately, the second option is subject to the approval of the destination country’s customs, and often they do not approve for disposal.
At JustShip, we try to help our customers prevent this from happening by giving guidance where possible regarding customs requirements. However, we do not offer a brokerage service, and our pricing model does not allow us the resources to give definitive advice, but only anecdotal advice. As a data point, only 1% of our shipments get returned.
