(IB) In bond simply means no VAT or DUTY is applicable, the wine however will need to be stored in a bonded warehouse such as Cellarers. The wine can be moved to different bonded warehouse if you so choose, fees and costs may apply.
DP) Duty Paid is where the VAT and duty is applied to the wine and generally means it’s going to be delivered to a non-bonded warehouse such as a private UK residential address. All taxes must be paid for us to be authorised to ship or deliver wine (unless the wine is bonded and being moved to another bonded warehouse or being shipped directly outside of the EU.)
The prevailing rate of UK Duty is added to the value of the goods, before the current rate of VAT is applied to the cost of goods plus Duty.
If export is to a non-EU country and the wine's status is currently In Bond, you will not need to pay Duty and VAT. All EU exports and domestic deliveries require Duty and VAT to be paid in advance.
