If you're based in Europe and Canada, there will be additional VAT to pay on your order in most instances. The good news is that parcels are sent DDP (Delivered Duty Paid). This means that any VAT charged to import books, is paid at the point of purchase and no extra import fees are due after this. For the current rates charged, see here for Europe and here for Canada.
Outside of Europe and Canada, the majority of countries do not charge additional import duties and VAT for books. With each parcel, we will attach the necessary paperwork and declarations. If you are charged additional fees, and believe this is an error, please contact Bitmap Books before paying, so we can investigate. Bitmap Books is not responsible for any additional VAT/duties on our books, unless the charges are due to our administrative error in the shipping documentation.
