Hi,
If you are located in the UK then you will only need to register for VAT if your turnover os over £85K.
Who should register for VAT (VAT Notice 700/1)
If you are exporting goods to the EU or beyond, then these will be zero rated exports and even if you breach the threshold you can apply for exemption from VAT registration.
Who should register for VAT (VAT Notice 700/1)
If you sell goods to both the UK and overseas, then you would need to calculate the combined turnover of these supplies and you could look at applying for exemption from registration if the majority of your sales are zero rated exports.
However if you are exporting goods of a value below £135 to consumers in the EU then there is an IOSS system in the EU which allows you to pay the import VAT of any EU member state you are exporting to on one IOSS return.
