In the event of a no-deal Brexit then there will be changes to the treatment of import VAT.
If your business is registered for VAT in the UK you will be able to account for import VAT on your VAT return. This means you will pay import VAT on your VAT return instead of when the goods arrive at the UK border.
You will need an Economic Operator Registration and Identification (EORI) number when the goods are imported to the UK
