Yes. For any orders dispatched from the UK into EU countries since 1st January 2021, we are required by customs to declare the following information on each exported package: customer contact email & phone number, plus the order selling price (i.e. your charge to the customer excluding shipping costs).
If this information is not supplied with your orders, we will use a default option which will show your company contact details and the price you were charged for the goods, marked-up by 50% to obscure your true costs and profits. This default option would result, however, in a small risk of your customer being charged extra duty, a situation we would clearly like to avoid. It might also lead to deliverability issues with your orders - and an associated increase in customer service support costs - as couriers will be using this data to contact customers if any delivery issues arise.
