Isle of Man Post Office (IOMPO) is advising customers about upcoming changes that may affect parcels and packets containing goods sent to European Union countries from Wednesday 1st July 2026.
The changes are being introduced by EU customs authorities and may mean that goods sent to EU destinations are subject to customs duties, taxes or handling fees. These charges are set by the destination country and are not charges made by IOMPO.
At first, any charges that apply will be collected from the recipient when the item is delivered. IOMPO is updating its systems so that, once the work is complete, senders will pay any applicable charges when they buy postage. This will help customers understand the full cost before sending their item and reduce the risk of unexpected charges for recipients.
To support the new requirements, IOMPO will move to using the CN23 customs declaration as the standard form for international items containing goods, replacing the CN22. The CN23 helps customers provide the information customs authorities need, such as what is in the parcel, where it is going, and the value of the contents.
Customers do not need to complete a CN23 for letters, paperwork or documents only. For parcels and packets containing goods, providing clear and accurate customs information will help destination customs authorities process items as smoothly as possible and reduce the chance of delays or returns.
IOMPO expects to complete its system changes by the end of August 2026. Until then, customers sending goods to the EU should make sure recipients are aware that charges may be payable on delivery.
Work is also continuing on a solution to reinstate parcel services to the United States. This remains dependent on there being no further changes announced by US authorities in the meantime.
These updates are part of IOMPO’s work to keep international postal services compliant and sustainable.
Customers sending goods overseas are encouraged to check the customs requirements for the destination country before posting. Further guidance is available from Post Office counters or at www.iompost.com/customs.
