When sending parcels outside the European Union (EU), make sure they are presented with the right forms. This makes it easier for the destination country’s customs service to process and far less likely they will be returned to you. Add your name and address to the top left hand corner of your package. This will enable your package should overseas customs authorities refuse it entry into their country. All items with contents up to the value of £270 must have a signed and dated customs declaration form CN22 attached to the front.
