InPost from ShipStation (FKA Yodel) is included with UK-based ShipStation accounts and provides domestic delivery services throughout the UK. InPost from ShipStation offers an option to print labels directly or print labels at an InPost Shop.
Updated Customs Description Requirements for Shipments to the EU
Beginning February 2nd, 2026 the European Union will have enhanced customs descriptions requirements. The new requirements will include a list of Stop words, which are generic descriptions that do not allow customs authorities to clearly identify the nature of the goods being imported.
Please see Country-Specific Cross-Border Shipping Requirements for more information on the updated description requirements.
