Hi Customs,
The guidance of OPR states below:
Authorisation by declaration
This is where we authorise you when we accept your export declaration at the border.
You can only use this type of authorisation when you’re sending goods outside the UK for repair.
You can only use this type of authorisation up to 3 times in a rolling year.
You cannot use this type of authorisation if:
• you’re using simplified declarations for export
• you want to use the equivalence or standard exchange system
• you’re applying for a retrospective or backdated authorisation
• your goods are subject to anti-dumping duty
• goods are valued at more than £500,000
If you a’re a private individual sending your own goods for repair overseas you can follow this process.
It might cost more than the tax owed, so you should check with your carrier before sending your goods.

Thank you.
