Hi,
Yes the Registration threshold is currently £90K for companies established in the UK and making taxable supplies in tthe UK.
If your business belongs outside the UK then there is no threshold and so it would mean registering for VAT when your first sale is made.
Please see the guidance below:
9. Non-established taxable persons — basic information
If you belong overseas and you are importing goods over a value of £135 and you are the importer of the goods in to the UK then you will be making taxable supplies here and so would need to register for VAT straight away.
If you are importing goods above a value of £135 and you are not the importer of the goods then there is no requirememnt to register for VAT.
If you are sending goods to the UK below a value of £135 to consumers in the UK then there will be a requirement to register for VAT immediately unless a marketplace is facilitating the sale of the goods.
Please see the guidance below:

Thank you.
