VAT
All wine is subject to Import Duty and VAT, however this is not charged whilst the wine is held under bond in a HMRC regulated warehouse.
Only if you choose to remove your wine from bond, will the Duty and VAT become payable at the current HMRC rate at that time. This is charged directly to the owner by the bonded warehouse on behalf of HMRC before the wine can be released.
So in summary, wine sold in bond is not subject to Duty or VAT unless it is removed from the warehouse
