Incorrect customs clearance costs
If the customs clearance costs are calculated based on the wrong value and you can prove it, you are allowed to file an objection. This can be done within 6 weeks of receiving your package. If you are claiming back customs clearance costs for a return shipment, you have up to 6 weeks after sending it to file an objection.
Gift with a value less than € 45,-
For gifts with a value up to € 45,- no VAT is applicable. This applies only if the package is from a private sender. In this context, 'gift' refers to items received as a gift from someone abroad. If you purchase something from abroad to give as a gift to someone else, it is not considered a gift.
Package returned
If you have returned the package, you can request a refund of the customs clearance costs, but only if the package has been returned to the country of origin (outside the EU).
