Unexpected extra fees are something no one ever looks forward to!
Customs duty fees are tariffs or taxes imposed on goods when they cross international borders.
There is always a chance that your country will charge customs/duties fees for goods over a certain value that are entering the country. Unfortunately this is out of our control because these fees are not collected by Inkbox.
We don't currently have the ability to include these fees at our checkout because every country has different policies that change frequently. Inkbox cannot cover any customs fees or duties, as stated on our shipping page.
