The main change to BFPO customers sending items to EU locations is the introduction of Harmonised System Codes which need to be included as part of the business to customer/e-commerce item customs declarations. As a basic rule, businesses who send international mail should already be including Harmonised System Codes as part of their item data declarations and from the 01 July 2023 any items addressed to EU locations that do not have mandatory data fields completed will be at risk of being delayed or even returned.
For Service Families:
The inclusion of Harmonised System Codes as part of the customs declaration requirement for Private BFPO Customers, posting items over a Post Office Counter remains undecided and BFPO will provide updates once these are confirmed by Royal Mail.
At this stage private customers are encouraged to read guidance on how to identify Harmonised System Codes which they may need before visiting their local Post Office to add to customs declarations.
Information regarding Harmonised System Codes and how to look them up can be found here and BFPO customers can also view Royal Mail guidance on international mail customs declarations here, which also includes a video guide on how to complete customs declaration forms.
