Amazon is part of VOEC and allows you to check an estimate for the customs fee, but I haven’t checked if there’s been any change. USA has a 15% tariff on Norway, but I don’t know if that is added to that existing Amazon estimate.
By the way, the Norwegian prime minister and finance minister (the latter being Jens Stoltenberg, previous NATO boss) met with Trump yesterday, and when the tariffs came up, he said “we could afford it” or something like that, because of our oil fund. I want to punch that red-haired cretin in the face every day.
