Even with the trade agreement, there will be some changes in parcel shipping to and from the UK, as the UK became a non-EU country on 1 January 2021. For goods with EU origin, there are basically zero customs duties and zero quotas. However, import VAT will still have to be paid. The same will apply to goods originating in the UK and imported into the EU. Please note that the exemption limit of 22 euros for goods from non-EU countries will cease to apply on 1 July 2021. This means that you will generally have to pay import duties on all goods you order from a third country such as the UK, in the country where the consumption takes place.
