Hi Joanne Baker,
You are not able to reclaim the import VAT as input tax without a C79.
We would recommend emailing the C79 Team for a copy but make sure that you give them the correct date as to when the import was made so that they send you the correct C79.
If the entry is not on the C79 then quite possibly the courier has made a mistake on the import entry and would need to correct it
Please email the team on
cbc-c79requests@hmrc.gov.uk
Thank you.
